I bought an atrix 4g mb860 with the lapdock locked to at&t.. latest android version 2.3.6..
I live in egypt..
first I called at&t asked for the unlock code, they gave it to me.
didnt work the unsuccessful
then i called again to make sure of the code but unfortunately they gave me the same code. they suggested i would call motorola
i called motorola they guided me to make a factory reset but did not solve the problem.
i unlocked the phone root
instal cwm
flashed diff radios
didnt help
flashed back 2.3.4
nothing yet
tried diff radios again
tried CM7.2
nothing worked
finaly i sent it to a repair shop
they said they were unable to unlock it.
now i do not know what to do????
i was thinking maybe doing advanced hacking to the software may help.
or eveeen changing the motherboard.. i thought of going to motorola asking them to replace the motherboard for me...
i want to know where does this ****en lock code is.. it is like a ghost i replaces software and boot loader where is that memory that hold the lock code and make it functionable on every software...

You're trying to sim unlock your phone, right? It's not a bootloader unlocking, i guess...

yes

Yeah, I'm not sure where the SIM lock code is either, but it is definitely not within the bootloader or boot or the ROM area. I think it might not be user-accessible at all. It's not like on Samsungs where you modify a file and that makes it unlocked.

I believe this is correct, I doubt it's in user accessible files. I'm no expert but if I had to guess it would be built into the firmware or a separate; small chip for storage that is inaccessible. It is only accessible via kernel probably, so it's very low level. Just a guess.
