iPhone 3GS stuck at logo after battery replacement
I replaced my iphone`s baterry with a new one and now it is stuck at logo.
The phone starts only when I connect it to the power cord (PC or wall adapter) and it is unrecognized by Itunes (itunes detects nothing actually)
I replaced the battery because it had almost 600 cycles and I supposed that was the problem. Before replacing the battery iphone could stay on only with a power cord.
Do I have to reset it or I fried the logic board and now it s useless?
