| Nothing worked. I tried restoring, installing sbingner tool and activate using itunes, but the battery still drained. I tried over and over until the iphone got stuck that no restore was possible ( I got error 21 or 1600 whenever I tried to restore )
THE ONLY SOLUTION THAT WORKED EVENTUALLY was the following one:
1. I used redsn0w to get the iphone into DFU mode - that solved the restoring problem
2. right after restoration using custom firmware of 4.2.1 I used an original AT&T sim to activate the phone using itunes.
3. I then installed a push using application like facebook and signed in.
4. only then I used the redsn0w tool to install cydia.
5. I installed ultrasn0w and replaced the sim
NO MORE BATTERY DRAINING.
Cheers and good luck |
