I tried to unlock my 3GS yesterday and failed. As I was installing baseband 06.15.00 my power shut off and sent my phone into the Recovery Loop. At the time of power outage my iPhone was running FW 4.2.1 and again the baseband was being flashed. Since then i have been trying to restore my phone to a useable state but to no avail. I need help all the programs I have used (RecBoot, EasyRecovery, iRecovery, TinyUmbrella) don't do anything to bring my iPhone back to life. I need expert help, can some one provide that help please? If any further information that might be needed to resolve my problem can be given I just wanted to send out an SOS.
