My iphone 3G 4.1 firmware, crashes after 5 seconds of booting and then starts booting again and crashes again and on and on, when I connect it to the pc it boots correctly but when I disconnect it it's matter of time to crash again, the "slide to power off" option appears without me pressing anything. Please help me i'm very frustrated and I need help

need info
Jailbroken? If yes then which one?

Probably the best is to restore to factory and then Jailbreak again will be the answer in any case.

may be a battery issue, i would look at getting a new battery.

Thank you, I'm jailbroken with limera1n and already restored once. Is it easy to change the battery, do you recommend getting a new housing and battery? Because the lock button only works sometimes
