Recalibration, band conversion and bug #1024 rework

2018-02-14 Thread Mychaela Falconia
Hello OM community,

I am pleased to announce that my company Falconia Partners LLC is now
offering GSM RF tract recalibration services for Openmoko's Neo 1973
and Neo FreeRunner devices.  Like all other commercial GSM phones and
modems, these smartphones had their GSM RF parameters individually
calibrated on the factory production line.  This factory calibration
normally persists for the lifetime of the device, but because the
calibration values are stored in the Calypso modem's flash file
system, it is possible that some Neo owners may have lost theirs as a
result of careless playing with modem flashing tools.  The latter
scenario is quite likely to have happened in the bad old days before
FreeCalypso when the modem was treated as some kind of "thou shalt not
enter" forbidden zone, and the modem flashing tools and documentation
were available only in a hush-hush, whisper-whisper manner.  GSM RF
calibration also needs to be redone if the RF hardware has been
physically modified in any way, e.g., to convert a 900 MHz device to
850 MHz or vice-versa.

Because my company produces new Calypso GSM modems that are very
similar to Openmoko's, we have the necessary facilities to perform our
own RF calibration that is no worse than what OM's factory did.  The
RF test instrument that is used to perform the calibration is a
Rohde&Schwarz CMU200, and this instrument itself needs to be kept in
good calibration standing - the chain of traceability goes back to
national standards labs like NIST.  Our CMU200 instrument has just
been calibrated by Rohde&Schwarz in Maryland; here is the official
calibration certificate:

https://www.freecalypso.org/members/falcon/calibration/CD_5000-309076293.pdf

In addition to the measuring instrument, the process of calibrating
the RF tract on a Calypso GSM device involves special software that
talks both to the firmware running on the Calypso (which naturally
needs to be TI-based) and to the CMU200 or other external RF test
equipment.  The original software that was used by OM's factory
appears to have been lost, hence an entirely new replacement had to be
developed from scratch here at Falconia Partners LLC, based on the
available bits of documentation from TI and meticulous reverse
engineering.  Our new calibration software is freely published, so you
can see exactly what we do when we calibrate a Calypso GSM device:

https://bitbucket.org/falconian/fc-rfcal-tools

If anyone has a GTA02 or GTA01 device that needs to be recalibrated or
could benefit from such, you can send it to Falconia Partners LLC to
be serviced.  As long as the demand is low, there will be no charge
for the recalibration service other than return shipping.  If you are
going to sending your device in for service, please take the battery
out, i.e., send the device WITHOUT the battery.  Postal services have
become very uptight about lithium batteries recently, hence the return
shipping will cost a lot more if I have to deal with the extra
bureaucratic hurdles of shipping the device back to you with that
Li-ion battery in it.

The calibration service is completely non-invasive, i.e., your device
won't need to be disassembled beyond taking the back cover off.  Your
Neo will have 3 cables plugged into it (USB for talking to U-Boot,
another USB-serial cable in the headset jack for talking to the
Calypso, and an RF test cable going to the CMU200 inserted into the RF
test port under the back cover), the application processor will be
booted into NOR U-Boot, the latter will be used to execute neo gsm on
and neo gsm off commands via USB, and the headset jack serial port
will be used to operate on the Calypso modem.  Whatever software you
are running on the phone's application processor will be left
completely untouched.

If there is interest, my company may also be able to offer a band
conversion service, i.e., converting a 900 MHz FreeRunner to 850 MHz
or vice-versa.  To make such conversion, one SAW filter part in the
GSM section of the motherboard needs to be changed (populate Epcos
B7820 for 900 MHz or B7845 for 850 MHz), followed by recalibration.
However, unlike pure recalibration, band conversion would require a
bit of invasive surgery on the hardware, and this hw surgery would
need to be performed at a professional board assembly and rework shop.
If there is any serious interest, I can have a discussion with
Technotronix (the shop where our new FreeCalypso modem boards are
assembled) and see if they would be able to perform rework on Openmoko
devices, and how much they would charge for the service.  I won't be
adding any margin of my own on top of whatever Technotronix folks will
charge, but I would need to act as a middlewoman for logistics because
devices would need to be recalibrated after the SAW filter change, and
the calibration station with the CMU200 (a big, heavy and expensive
instrument) resides in my own lab, not at Technotronix.

Finally, if anyone

Neo FR disassembly for bug #1024 rework

2018-01-05 Thread Mychaela Falconia
Hello OM community,

I know that a good number of Neo FreeRunner units have been subjected
to the hardware rework to fix the infamous bug #1024, and it is my
understanding that one or more shops used to perform this rework
service professionally once upon a time.  I am now looking into the
possibility of having my company Falconia Partners LLC offer this hw
rework service, as I have heard reports from FreeRunner owners who say
that their units never got the rework and do suffer from the bug, and
I would also like to be able to offer a band conversion service, i.e.,
converting any given FreeRunner between 850 MHz and 900 MHz bands in
either direction.  The band conversion would involve changing one SAW
filter component at reference designator U402 (populate Epcos B7820
for 900 MHz or B7845 for 850 MHz, I have the parts readily available)
followed by recalibration - and my little company has just the right
RF test equipment setup (and newly developed calibration software that
fully replicates the functionality of the apparently-lost Windows
version used by OM/FIC) to do the latter.

The extent of required disassembly is exactly the same for bug #1024
rework and for the SAW filter change - in both cases the metal
shieldcan cover over the GSM section of the motherboard needs to be
removed, and both reworks can be done in the same surgery.

I do wonder, however, if any of the people who used to perform bug
#1024 rework in the past on a professional basis (i.e., on customer
devices, not their own personal ones) might be willing to share some
tips as to what would be the absolutely least invasive way to open
that shieldcan and then put it all back together after the surgery.

One complication that exists on GTA02 devices but not on GTA01 (nor on
my newly made FCDEV3B modems) is that the WLAN daughterboard sits
directly on top of the shieldcan cover over the GSM section, and the
two are bonded together with some material that seems to be some form
of conductive glue.  It is not a strong glue, i.e., the WLAN module
can be easily pulled off by hand, but pulling it off like this leaves
a mess underneath, and thus I assume that my naive way of doing it is
probably not the right way.

Hence I wonder if any of the people who used to do the rework for bug
#1024 professionally might be willing to share the secret of how to
do it right:

1) Did you remove the WLAN daughterboard first and then lift the
shieldcan cover, or did you somehow remove these two pieces together
so they remain attached to each other with that bonding material?

2) If you removed the two pieces separately, how did you restore the
bonding between them upon reassembly?

3) If it is possible to remove the shieldcan cover along with the WLAN
module on top of it as a single piece, how does one do it?

TIA for any tips,
Mychaela

Hi Nikolaus,

unfortunately, we don't have yet enough experiences, people and
resources for organizing international english-spoken event. Although,
I like to see this happening in the future, when more people gets
involved in organisation. Next year, we would like to invite some

yes, no problem.

All three reworks are done in very different areas of the device (Buzz  
is done at the Microphone; #1024 within the tin-can under the WLAN  
module and the Bass-Rework under the tin-can under the Bluetooth  
module). And therefore they can be done independently - or all

And, they use professional equipment that does the least harm to the

Dear Freerunner owners in the EU harmonized market,

a known problem of the Neo Freerunner design is that the headset  
output lacks some low frequency signals (bass). Thererfore music  
played through the headsets does not sound as expected and compared to  
other digital music players.
There is an improvement rework by adding larger coupling capacitors to  
the output amplifier. This became known as the Bass Rework 
(http://wiki.openmoko.org/wiki/GTA02_bass_fix 
). Although there is a description of a rework solution 
(http://people.openmoko.org/andy/additional-headset-audio-caps.pdf 
) we do not expect that you can do it yourself and not in the required  
quality. Just a note what the problem is: we need 47 uF in 0805  
dimensions and they are a little expensive and difficult to get and  
space is very close. Therefore, we have worked on a professional  
approach.

With the help of a local SMD specialist company in Munich, we can now  
offer a rework service to those who want to improve audio quality. The  
price is 49 EUR (incl. German VAT) plus shipment.

Details can be found at:

http://www.handheld-linux.com/wiki.php?page=Bass-Rework

Finally a note of caution: acoustic quality is very subjective so that  
we can't guarantee that the result is good enough for your  
expectations. We can only guarantee that there is a technical  
improvement.

Can you give me an estimate of how much and how long it would take to send
a fixed freerunner from your place to Portugal?

I want to know the total cost before deciding wether to order it from you...

Have any effords been done to prepare a bass-fix?
Can you guess a date where and if you will offer it?
When it will be offered I would prefer to let both be fixed.

I did a few tests with #1024-fixed A6 (bouncing before) with 2 batteries
(one-year-old-one, new-one) and in both cases I was able to get about 100hours
of standby (just waking it up from time to time, GSM on, everything else
hopefully off; shr-u).

What I have to mention though is that sometimes my fr wakes up autonomously
(and goes to suspend after a while of inactivity) (I suppose this can be due
to some GSM events - but not on a 'normal' cell roam).. so while I didn't see
the phone to wake up during tests it might have happened.

Still, 4 days is a very good improvement :)

No. You have to open a different tin can. You have to cut and solder  
different cables. The test procedure is different.

We want to make sure that every fix we offer really works, is  
reproducible and has high quality. Therfore, it is not "just" doing  
the same thing again.

The common work is of course the logistics which is done only once.

But having bass rework the same time as the 1024 fix, its a huge
benefit and also
more attractive service.

I for example will never send my phone for just to the #1024 fix,
because I plan
to in a way or another apply the bass fix.
So no point to sending you to do the half of the job. (the easier half actually)

Frankly, when you dismounted the phone, and you have the necessary

During first live tests this week, qtmoko managed to last two full days
(plus nights) of quite a bit of calls and messaging with occasional
checking of status, gprs connection andgps. Previously, one day of use
would drain the battery so this is an improvement. As the testing is
subjective to usage, we will see in the near future what the real stand
by time might be.

Re: #1024-rework service available

2009-10-23 Thread Dr. H. Nikolaus Schaller
Hi all,
here some answers to recent questions:

Q: Rework service for USA, Canada, Australia?
A: unfortunately handling import/re-export is too much paperwork and  
if anything goes wrong, someone might have to pay taxes again. And,  
shipment is either very slow or much more expensive than within EU.  
This would make it cheaper to buy a new one...
You could ask SDG Systems since they also had organized the Buzz- 
Rework in Canada, i.e. they have a company capable of doing it.

Q: Bass-Rework?
A: we currently have no plans because it is again a different work  
which has to be evaluated, tested, prepared for the public. And demand  
appears to be lower.

Q: how much does it improve?
A: here is a report of 143 hours standby time:
http://totalueberwachung.de/blog/2009/06/03/freerunner-deep-sleep-standby-time

Q: when does GTA02-core or GTA03 come fixing all these issues?
A: we don't know either

In optimal conditions, it's going to double your standby time from ~70h
to ~140h.

Hi,

thanks for offering this service! (although too bad I already sent my
device once to Germany)
can you give us an indication on how much this would improve batterylife?

I'm assuming it only extends standby-time.

I once saw a graph that indicated that it was a huge boost, but can't
find it anymore

Hi. I'm in Melbourne too.

Needing to buzz fix an A6 I asked a few electronics engineers. I was looking 
for somebody who would do delicate soldering work for an hourly rate. The 
consensus from people I spoke to was that while there are a few small 
businesses who do electronic work, few would be interested in small jobs.

A co-worker of mine offered to do the buzz fix for me. This person tends to 
over rate his ability. I should have remembered this when I agreed for him to 
do the work. I plan to tool up and redo the soldering on that phone in the next 
couple of weeks.

The problem with little jobs like this is liability. If he stuffs up, who takes 
responsibility? On small jobs it is impossible to get insurance.

So I am going to do a buzz fix soon. The #1024 fix seems more complicated 
because you have to disassemble parts of the phone which may be hard to put 
back together. I might try this procedure on the phone which I am going to do 
the buzz fix on. I can more afford to stuff that one up.

I will post the results here:

I think the command AT%SLEEP=4 enables the deep sleep of the modem.

No, we offer it as long as there is demand. Well, nobody knows what we  
can provide in 10 or 20 years :) And if we extrapolate technology  
innovation you probably won't be interested then...

Do you need to enable deep sleep mode before doing the test? Also is this a

#1024-rework service available

2009-10-21 Thread Dr . H . Nikolaus Schaller
Hi all,

some users of Neo Freerunner devices have experienced a limited  
standby time if the GSM modem goes to the deepest sleep mode. This  
became known as the #1024 bug, because that was the number it got in  
the bug tracker (https://docs.openmoko.org/trac/ticket/1024). The  
software workaround was to disable sleep mode 4 as the default.  
Although there is a description of a hardware rework solution 
(http://lists.openmoko.org/pipermail/hardware/2009-May/001192.html 
) we do not expect that you can do it yourself. Therefore, we have  
worked on a professional approach.

With the help of a local SMD specialist company in Munich, Golden  
Delicious Computers can now offer a rework service to those who really  
suffer from this problem. Price is 45 EUR (incl. German VAT of 19%).  
If you combine with the Buzz-Rework (for A5 and A6 versions only) it  
is 75 EUR. And there is a rebate for groups of 5 or 10 units.

rework

2009-03-10 Thread Petr Vanek
hi,

i was lucky enough to get someone to perform the gsm buzz rework.

i find the images used in the
http://people.openmoko.org/joerg/GSM_EMI_noise/big-C_rework_SOP_rc2.pdf
quite rather _small_ therefore please find some of my pictures done via
microscope here: http://vanous.penguin.cz/files/om/SOP/

Please feel free to use them to improve your manual.

Also, we found that placing the 100uF cap according to the manual is
rather strange and could cause problems in future - so we placed the
cap in a way that is will be soldered to the PCB on both ends, making
it hold really tight (that particular picture is somewhat blurry)

We didn't have 2k2 in 0402 size so we used 2x 80Ohm in series (we just
built a A shape with them).

The fix works - done on two units, one showed gsm buzz before and now
it's gone.

Some of the other pictures show D4301, D4302, as under the microscope we
found one of them damaged from manufacturing - placing the cover -
something om might watch for.

cheers
petr

We don't supply a USB device breakout cable at all, but we can specify how 
they should be made to do detection. Is there a standard set of ID levels for 
OTG that we could follow?

   I think it won't solve the problem of DC through the speakers. Think of
the case where the left output is at 0 V and the right output is at 3 V.

Yes it's a different way to come at it.

By putting the caps in that case void 100uF will fit easily, but it
needs long leads, the leads violate the can frame / can clearance, you
have to cut the can and make some kind of grommet for the leads to pass
through.  I dunno what happens to BT antenna effectiveness either.

The way I documented you keep the leads short, the components are all in

I'm not an electrical engineer, but won't this increase the bleed between
left and right channels? Because, for instance, while the left is at 0V and
the right is higher, the "ground" side of the right speaker will be
connected, effectively, to two grounds, one via an inductive load and one
via a capacitative load. I'd guess some current will flow through each, and
the less transient the voltage on the right output, the greater the
proportion that will flow through both speakers. I guess this could possibly
lead to speaker burnout if the headphones had low power ratings...

This is all based on my vague understanding that one of the primary purposes
of inline capacitors on audio outputs is to prevent DC current through the
load.

Sorry if I've got this hopelessly wrong.

The headphone action is overloaded with a digital connection to the GSM

as some protection against large voltages developing on what would be
floating nets on headset insertion, etc.

Yes I didn't get your point.  But I don't think it's the same action as
one cap before each transducer and a direct common low-impedence ground
reference.  The two signals will mix where they join at the single
capacitor and the impedence depends on the frequency.

Anyway, some setup will be necessary, right? A usb headset headset will

You misunderstand. I did not propose to do only one channel.
I planned on shorting both the small caps. Then, instead of one big cap 
on each of the stereo lines: LEave the stereo lines connected as-is. 
Break the ground line (which is common to both channels) and insert a 
single big cap there instead. Slightly less work, and perhaps a bigger 
capacitor will fit. (It'd probably have to be bigger too, as the two 
channels often enough have the same signal.)

I understand that it won't be trivial. Maybe not for me. But if openmoko 
creates a standard procedure for this improvement too, then I can have 
an electronic repair shop do everything in one go - both buzz and bass 
fixes. That will cost me less than having the fixes done separately, 
even if both fixes together may cost a bit more than buzz only. I hope 
to ship the phone only once, the repair guy will need to open it only 
once...

A mass fix will be especially cheap - a good technician doing identical 
fixes on a big stack of phones won't need much time on each. It seems 
like pulster might set up something like that - but they surely need a 
procedure, before they can train someone for the job!

Have you tried tweaking the alsa profiles and set Bass Filter to
either 100Hz @ 8kHz (== 600Hz @ 48kHz) or 200Hz @ 8kHz (== 1200Hz @
48kHz) and Bass Boost to 15? I find the quality just fine for eg.
in-car music playing. Even when using headphones (Koss KSC-35) I find
the quality acceptable, even though the color of the sound is not
completely neutral.

I tend to prefer 200Hz @ 8kHz, and probably the high-pass filter
effect of the output on Neo is indeed quite high, though sometimes I
wonder if the midrange is overemphasized with that setting still.

I was planning to see about playing back a frequency sweep on Neo, but
seemingly forgot about it. Anyway, I now put one 20Hz-2Hz sweep
file at http://users.tkk.fi/~tajyrink/moko/20-20k_60s.ogg (vorbis
quality 8, should be good enough), if someone with proper(ish)
recording equipment can record with eg. 100Hz @ 8kHz and 200Hz @ 8kHz
settings with Bass Boost at some level like 15. I don't know what
quality an average motherboard "HD" Audio recording is, but will try
it anyway myself at some point with various settings to see what kind
of slopes one gets.

There are a couple of 1K resistors to 0V that will then connect directly
~ to the amp outputs all the time before the new DC blocking caps you
will add back in.  But thanks to some recent patches by Mark Brown on
andy-tracking, we should  keep the amp turned off more often.

Lifting the can and meddling with the caps is nontrivial.  Somebody did

an experimental frame of mind and can deal with the fiddling and risk
involved.

Not yet, jsut descriptions of workarounds.

Two small capacitors needs to be replaced with much bigger ones.
Unfortunately, they are in a shielded enclosure where there apparently 
isn't room for sufficiently big capacitors.

One aproach then, is to put the big caps outside the shield, and use 
wires to connect them inside. But that might lead buzz into the shielded 
unit - not recommended.

Another approach is to short-circuit those small capacitors, and put big 
capacitors on the headset wire instead. But that means only that one 
headset fits your freerunner.

I have suggested a refinement on the second approach: short the small 
capacitors. Add big caps outside the shielded unit - there are places 
with room. But don't put wires from the caps into the shielded
unit. Connect them to the headset plug instead, and break the plug's 
normal connection to the circuit board. This approach won't pick up any 
more buzz than the headset based solution, or the current bassless 
setup. And you can use any headset you want.

The big question is - is it safe to short those small capacitors? Or 
will that have other side effects, such as draining the battery or 
disturbing sound on the built-in speaker?

Another question - is a single big capacitor enough, if it is put into 
the ground line  instead of having one cap for each of the stereo

I don't have any influence over that assignment in any rootfs.

But there's a lot of flexibility about how to tell which LED what you
want it to show.  The existing charging LED stuff is done with LED Triggers

http://git.openmoko.org/?p=kernel.git;a=blob;f=Documentation/leds-class.txt;h=6399557cdab3d6542a0feea0c0cd2c6b2af5ffad;hb=68f30b2e0d0f04093b491052690db3fee382090a

But actually there are a lot of triggers including one for SD card
access.  You can use /sys to assign a particular LED to be under the
control of a particular trigger.  So you can assign the AUX LED to be
controlled by the charging trigger just with an echo.

I did not find a way myself to list the triggers available in the kernel
otherwise I would mention it; if someone found one I'm also interested
to know.

Thats how it is used currently in Om2008.x. Now that I know of the issue I 
think it would make sense to change the framework to also use this LED as the 
battery indicator

I also like to use the Orange/Blue LEDs to indicate the current USB mode 
state:
Off -> Device Mode + Networking
Orange -> Device Mode + Storage
Blue -> Host Mode
Blue+Orange -> Powered Host mode

Using Orange/Blue as a charging indicator wastes all 4 LEDs to just indicate 
charging/not charging...
The red one is useless due to this bug. The orange and blue are busy because 
of the charging indication and you can't use the violet mode because you can't 
reuse the orange and blue ones...

So, please consider changing the framework to use the red LED to indicate the 
battery charge state. 

Michael

No there's no real hardware fix that's practical.

We could have done something extreme like PWM the enable by software in
FIQ ISR, but it would result in dim AUX LED even so, since the LED is
not seeing the excess current but just normally lit.

It was fixed on A6, I'm afraid we just have to let it lie and not use
the AUX LED much as pointed out unless we're on external power.

Overall, it's a small issue about small excess current on one GPIO that
spends 99.9% of its life off anyway, as a customer this would bother me
so much less than the buzz or bass issues it wouldn't really bother me
at all.

The power is consumed by driving a common-emitter transistor driver for LED 
without base resistor. Current flows from GPIO via base to emitter, and it 
for sure had been wiser to drive LED directly from GPIO ;-), instead of 
burning 40mA base current for 10mA collector current. (ballpark numbers)


For the non-fixed AUX LED: I wasn't aware these versions have been sold :-/

Ouch. I just tested mine, and the AUX LED really uses that much (about

Johnny Tenfinger is right despite it sounds strange.  On some or all A5s
there is no base current limit resistor on the bipolar transistor used
to light the AUX LED.

This "50mA" fault current then flows not through the LED (which has a
reasonable series current limit resistor), but through the GPIO IO cell
and the driver transistor base.

Your mentioned 50mA for the AUX LED is ridiculous. It would burn out
with this high current. Normal LEDs only use ~20mA and low current LEDs
~2mA. 50mA would be for a higher power led which isn't build into the

If I ship the phone somewhere to have a technician fix the buzz, I 
definitely want the "small capacitors on headset output" issue fixed too.

The capacitor, combined with the resistance of earphones, form a 
high-pass filter.

The cutoff frequency is 1/(2*pi*R*C), where R is headphone resistance 
and C is the size of the capacitor. The capacitor in the FR has been 
reported as 1 microfarad. My headset is about 40 ohm, which gives a 
cutoff frequency of about 4kHz.

At 4kHz the sound is halved, and drops by 6db per octave below that. 
Above, the sound is almost normal. Unfortunately, most of the sound we 
hear is below 4kHz.

A headset usually works down to about 20HZ. If I want the cutoff 
frequency there, a 200 microfarad capacitor is needed.

Is there a plan for such a fix as well?

I heartily concur. In fact, one of the things that's made me hold off
buying a FR is that there isn't an easy way to get this stuff done. If
the reseller could make the fixes for me for a reasonable charge, and
under warranty, the FR would suddenly become a much more attractive

Re: Crackly Calls and Battery Tips! A5/A6 rework. Corrected URL

2008-12-25 Thread Steve Mosher
The A5 to A6 rework was handled at the factory for the most part.
see http://wiki.openmoko.org/wiki/GTA02_revisions

for details.

WRT the a5/a6 rework, I've got to get back with Joerg and Tony Tu
to finalize the SOP and then put in place a testing method. One problem
is that the Buzz can be location specific. For example, when the Buzz 
first became apparently Sean flew out to me in SF with a sample of
phone that buzzed. Mine didnt. ( he was on other travel ) Anyways,
we turned on his phone--no buzz. Now imagine if you have a buzz and
send it to person X to fix it. As part of the testing person X would
operate the phone and verify that it buzzed. Well, what if it doesnt?
does he apply the fix? If it does buzz applying the fix is a 
straightforward decision. On completion of the fix the phone is tested 
again and then returned. Does it still buzz after it's returned?

So, here is where I stand. my todo list.

1. finalize the SOP and testing protocal.
2. recruit individuals and organizations to do the field rework.
3. Procure parts required for the fix. These parts will be given away
either through distys or direct to people willing to do fixes.
4. Finalize rewards program.

I'm not likely to get to any of this done before CES which is jan 8-11.
It's not a matter of me taking time off for Xmas, but rather the Everest 
of other tasks and priorities. Experienced sherpas apply within.

You can find out the version you have via software query.
otherwise take the front faceplate off and see the PCB rev
printed there.

There are roughly 3K V5 in the feild all built early on.. in june/july
I believe, so the datecode can also give you a clue.

There is no rework for a5-a6. the differences are listed in the
wiki and I'm fairly confident that a large portion of the a5 were
reworked, covered this a long time ago.. anyways, both a5/a6 can be 
reworked to improve the buzz issue some people have.

Hello list,
I wonder if anyone in Chile with a freerunner is interested in doing the

making a big discount if they repair 10 or more units.
If anyone is interested just email me.

2008-12-18 Thread Vasco Névoa
I did the big-c buzzing rework myself, with the precious help of a  
much more smd-experienced colleague.
It was very difficult to replace the resistor because of the proximity  
of the components around the mic. A very sharp soldering iron is  
critical.
I used a 1k resistor (didn't have a 2k2 of the same size at hand), and  
a 100uF/10V tantalum capacitor.
So far, so good! The buzz seems to be gone for good. :)
One caller has reported that I sounded like "at the bottom of a pit",  
but this can be the other older issue...

Joel, Joerg overlooked your question on the community mailing list,
you should have asked at hardware list instead. I asked him on IRC:
here's the answer:

12:57 < PaulFertser> DocScrutinizer: could you please answer a
question wrt capacitor type for the gsm buzz fix? Joel Newkirk asks
whether he can use tantalum instead of ceramic ones as tantalum are

13:00 < DocScrutinizer> PaulFertser: we don't have any tantalum caps
here, and I would guess they are just too big. I was about to suggest
a free caeramic cap for everyone asking for it. actually I'll bring a
handfull of those to Germany on Sunday
13:00 < DocScrutinizer> PaulFertser: technically there is nothing
wrong with tantalum
13:01 < DocScrutinizer> though I'd guess they are somewhat harder to
solder, as they're basically electrolytic caps and so won't stand much
heat
13:01 < PaulFertser> DocScrutinizer: if you don't mind, i'm going to
post your answer on the community mailing list in the corresponding
thread.
13:02 < DocScrutinizer> go ahead, you're welcome
13:02 < DocScrutinizer> just quote this dialog is fine
13:04 < DocScrutinizer> also, to whom it may concern, I plan to join
25C3 congress in Berlin, and maybe rework a couple of devices there
for free, or at very least give away caps

Thanks - that was most of what I was needing.  Unfortunately it doesn't
identify the real estate occupied by C1767 there, nor in the component
placement diagrams.

Can someone point me at the right spot on the board?  If it's got enough
room for the same 3528 cap we're looking at for the big-C rework (which I
doubt, though it looks like it will fit for the big-C position) that would
be great.

Thanks, there's something of that size there.  Also the date is
20080717, and /proc/cpuinfo's Revision is 0360.  So mine is a v6.

It's a bigger C1767 - according to the schematics it's 4.7uF on A5, 47uF on A6 
and 100uF on A7. Werner's writeup of the investigations is here:

Take out the battery, SIM and uSD.  Where the contacts for the uSD meet the
PC board there will be a SMD capacitor (about .5x1mm) between two of the
contacts, _IF_ it's newer than V5.  I don't know what the physical
difference is for the power tweak. (V6 can power up from wall power without
battery) 

You can also look at the datecode on the serial/imei sticker under the
battery, but I don't know the exact cutoff date.  I know that datecodes
from June are V5 and from August are V6.

a cap on the two pins of the uSD socket is pretty trivial if you're already

I've talked to a local electronics repair shop here in Bergen, Norway
and they said they will do this operation. There, however, should be a
package which contain all relevant documentation and complete
circuitry and dismantling the freerunner to help a technician easily
and quickly do this operation and not waste time finding the
documents.
