Hi Nicolas,
I've also tried to hack a little with the fwtftpd today to serve the cfg.txt
to the phones (and also updates to software). I cannot get it to accept the
cfg.txt i give it though - have anyone successfully served that file to
their GS phone? or made it update the firmware with fwtftpd?
I made a updated fwftpd.java file - anyone is welcome to test it here:
http://musimi.dk/fwtftpd.java
it uses the mac address of the GS phone and then sends the /cfg/{MAC}.txt
file when the phone requests the cfg.txt
Please help with getting the phone to accept the config file? - should i
send something back as OptionsACK to show the GS phone that it is ok to
update?
Cheers,
Jens Davidsen

[Asterisk-Users] Grandstream cfg.txt hacking?
Hi list, I'm trying to figure out the format of the binary data in cfg.txt - so i'm looking for someone with a GS phone/adapter from sipphone.com (bought there so it downloads the config there also). I suppose they use GAPS there and also download the cfg.txt configuration there? Please send tcpdump data of the tftp session - or other udp dump data. I have a tftpd server hacked and ready to serve the configs if we can just get the format of the file.

Re: [Asterisk-Users] New Firmware for Grandstream Phones - Supports CFG by MAC address
Hi list, I have worked a little on debugging the Grandstream cfg.txt file and here is what i found out so far: The binary header is like this: 00 00 01 00 (always the same start) 52 d2 (checksum of 2 bytes) 00 0b 82 00 XX XX (phones mac address in hex) 0d 0a 0d 0a (two carriage return and new lines) after this header the config follows in clear text - looks url encoded like : P2=admin&P8=0... etc. (find the variables in the webconfig of the phone) the clear text is terminated with a 00 byte If anyone figures out how to calculate the 2 byte checksum then please tell me ;-) (this information is from older firmwares - didnt check if they changed binary header in the newer versions...)
