Replaced housing. Now all that comes up is the apple logo
Hi. I replaced the back housing of an iphone 3g with one i bought on Ebay. Now when I put the logic board in, it just boots up to the apple logo for thirty seconds and shuts off. I replaced the dock connector, the battery and the audio flex assembly to try and isolate the problem but nothing helps. Also, I've verified that the logic board works in another phone. Any suggestions?
