does anyone know a way to get my FP1U working again? It does not start at all (no LED, screen is & remains black), even though I have not dropped or otherwise mistreated it, Battery was not empty before the phone stopped working.
When I attach a charging cable (with or without battery), there’s no LED or screen reaction.
Here’s what I already tried without success:
used another FP1U battery (which works fine with other FP1U)
attached charger & cable with & without battery in FP (both work fine with other FP1U)
