Why is phone overheating and won't start after changing battery?
I replaced the battery on my phone with what looks like OEM spec battery 616-0435. This is jailbroken with Greenpois0n at OS 4.2.1.
All went well except that the instructions that came with it didn't mention pull the screw and clip for the camera, so reinstalling the motherboard and getting the camera re-connected was difficult and the first time (before I learned to remove the camera with the motherboard, the connector probably wasn't fully or properly seated. Initially the phone wouldn't power on, so I connected to wall charger. At the point the Apple / then Greenpois0n icons came on and then eventually it went into emergency mode with the graphic on the screen showing me to link to iTunes.
I tried this, but iTunes never found the phone. After disassembling and rechecking all connections a couple of time, I hooked it back up to power, but nothing happened, then I noticed that the phone started getting hot as it charged. I switched back to the old battery (which was functional, but losing it's steam). Same result (no power-on and overheating). Any ideas?
Is this a good question?
