This is the mode that can be forced on start or the only one available if the boot loader is damaged.
It is supposed to give some diagnostic about what is wrong with the phone and let you flash the boot loader etc.
Does anybody know how it works and what tools to use? Has anybody reverse engineered the protocol?
