Dear friends. I am looking for some help here. I had iPad 2 wifi which was disabled and flashed with signed firmware and it was on hello screen after restoring. When I tried to activate, I always got an error message giving me an option of taking back for apple service center for replacement. It was not asking for any apple id. So, I opened it and Removed resistors r1204 and r1205 to be able to flash again and activate successfully. But after that when I connect the phone to pc to flash with itunes or 3u tools it can not, device does not show serial number, only ecid, only dfu mode.
here is log from flashing with 3u tools
