Booting issue - Dead Battery?
Alright, so. My iPhone 3G (8GB Black) turned off randomly one day and I plugged it into power. The apple logo showed up as per normal during boot, but after 40 seconds the screen dimmed and the device freezes. The same happens with the USB lead too. If it hasnt gotten to the frozen mark and I unplug it, it will then freeze.
The dimmed apple logo remains on the screen, even when I disconnect the LCD screen.
I was able to enter DFU mode, but upon restoring, iTunes would spit out an error 23 and the device would freeze.
Ive tried taking out the battery and booting it via AC power, but again it will freeze after the 40 seconds. Ive also bought a new OEM battery for it, but still receiving the same problems..
Ive checked all terminals to make sure theyre clean. Was a little bit of sand and dirt, but its all clean now.
The phone has had previous temperature warnings (about 1 month prior to the issue)
EDIT: USB wont trigger a boot either after battery replace. Only on AC power
Is this a good question?
