iPhone 3G not powering up after housing change, why?
Hi! Changed the housing on an iPhone 3G, now it just won't power up. The power button/flex is not the culprit here, because if it's on the charger I can get the Apple logo for about 5 seconds; then the screen goes blank like an old Game Boy (fades out as if power abruptly cut)
It will not enter recovery or DFU mode because I can see the screen flashing black every 1-2 seconds when plugged into a computer.
Tried replacing the battery, no go. Reseated the board, no go. Cleaned it with 99% IPA, let it dry, gave it a go with the heat gun, no go. I put another logic board in there to test fitment, grounding, etc. it works!
Ordered a dock flex assembly, going to see if it helps. Anyone have any ideas? It's running 3.1.3 (Sn0wbreeze pwned) if that helps.
Is this a good question?
