I'm trying to help a friend who bricked his iPhone 3GS. No clue what he really did but here's the symptom:
- phone seems locked in DFU mode
- iTunes brings an error 21 while trying to restore
- iRecovery can connect, 'bgcolor' command works
- iRecovery 'setenv' brings the error 'nvram_save: no oldest bank previously saved, cannot continue'
Now I'm kind of stuck, like the phone
What could be tried to bring this phone back to life?
