The touchscreen on my FP2 started to become more and more insensitive during the past two months or so (letters along the left side of the keyboard not appearing when typing but appearing when phone turned 90°, then space bar not responding, then the comma producing a v, then etc.), so I bought a replacement module (yes, I know: support first…, but I’m not a patient person with certain things). Replacing following the ifixit how-to was a breeze, but now my phone won’t boot any more! I depress the power button once – nothing. I depress it twice – nothing. I keep it depressed for long, long, long… nothing but a short growl (actually a burring and vibrating) and then silence again.
Any suggestions what I might or should try? Thanks already.
