Comment (by johnv):
More info I received from Matt, who wrote the above patches:
"I've gotten similar reports about the PicoStation. It seems that UBNT has
switched to a different flash chip vendor some time ago, so depending on
the time and place you obtained your device, it may or may not work...
The kernel log will show which flash chip is used. One patch I backported
to CC fixes the locked flash issue with Macronix flash chip (model name
starts with "mx"), but we've found out that UBNT also uses Winbond flash
chips (which are detected as "s25fl064k" in the kernel log, which is
actually the name of a Spansion chip, but Winbond and Spansion share the
JEDEC identifier). I've tried to fix this up in the same way as the
Macronix flash was fixed (see [1]), but this fix was not effective."
All the BulletM2's we checked contain this s25fl064k chip, and in turn,
these patches do not solve the issue for now, for us. Perhaps some
BulletM2's use the chip that works with the above patch.
So the patches may work from some UBNT devices, but not all.
