My iPhone 4 has stopped turning on. I am trying to diagnose the cause of the problem. Holding home+power appears to do little, even after charging. I have taken the battery out (just in case this was an issue with the software being stuck in a bad state, although the screen looks visibly off).
I am wondering if it is possible to run the iPhone 4 without the battery through the cable only? (this has not worked for me but I am trying to narrow down the problem and this would eliminate the battery from the suspect list and leave the logic board). Does anyone have any experience troubleshooting these beyond swapping the charger, trying DFU mode and holding home/power?
Thanks,
M
