After repair, dies if back cover installed (works with cover removed)
Following your repair guide, I successfully replaced my iPhone 4S power flex cable, returning the power button to working order - great!
However, it seems I've done something wrong putting it back together, and can't for the life of me figure out what. Basically, the phone works fine as long as I keep the back cover off. When I replace the cover, the screen goes black (but remains dimly lit); if I press & hold power+home the screen will go off, but it won't come back on even if I remove the back panel and remove/replace the battery - until several hours later, seemingly once the battery has drained completely (the next time I get it back on, I get the 'battery empty' indicator). In other words, after it 'crashes,' if I leave the back panel off for i.e. a day then try it again, I can get the "dead battery screen" back - then I can charge it up and use it. But the moment the back cover is installed, it dies again.
Any idea of what might be messed up?
Thanks very much in advance...!
Is this a good question?
