When Brian was at my house a few weeks ago, he used the maemo ‘flasher’ to enable the R&D mode on my nokia 770. Basically, it allows you to do extra functions that you wouldn’t normally do; such as gaining root.
I noticed that the maemo website had a newer firmware ROM image than what was currently installed on my 770.
Because I noticed some problems with the current ROM image, I decided to update the firmware.
My concern was that if I updated the firmware, I would loose the R&D mode. As it turns out, the R&D mode flag is completely indepentent of the firmware update.
Now my 770 is on the 3.2005.51-13 firmware stack.
