"nokia lumia 900 wont turn on" için yanıtI did, but only because I wiped the phone to try and recover it.
"nokia lumia 900 wont turn on" için yanıtI had the same problem myself. The fix was to replace the battery in the phone. I ordered a replacement from Amazon.com. As I also had had to replace the screen just before that (my wife face planted the phone on a rock), I already possessed the required tools to take it apart - they came with the replacement screen. It needs a very small hex driver, a very small philips driver, a spudger and the SIM pin (or something similarly pointy, such as a needle, to remove the really long locking ping that runs the length of one side of the phone)
