I dont know what I did wrong but, here is the situation;
1. When I downgrade the firmware to 1.1.1, I can successfully jailbreak. But when I try to unlock with anysim 1.2.1u, the phone gives me an error when flashing the baseband. " anysim can not unlock this phone, please restart your phone etc."
2. When I try to virginze the phone (in case of anysim did something), the virginizer gives me "main script execution failed" error.
3. When I try to downgrade the firmware with bbdowngrader, again the phone gives me the same error "main script execution failed"
I can still see the IMEI and it is correct. But I'm suspicios that the baseband is corrupt. Is it?
