nokia firmware hacking

[||Joe]

i think the cpu and other parts of the phone should be programmed so that it would not be checking all the MSID and other bullshits. instead of studying the algorithm of the phone, of how it is checking the imei and other stuff for it to work. the main program or operating system of the phone should be hacked. does anyone here know how?

All security check routines are executed by MAD2 DSP, not by firmware in flash.
As far as I know, full ROM of MAD2 cannot be read, not to mention reprogramming it.
We can read COBBA-ID but writing new ID on COBBA-chip is impossible I belive.
