FP2 won't turn on since latest software update! :(

Has anybody else’s phone completely died since the latest update? My phone battery was close to running out and it restarted, and was installing the update (which it’s done before no problems). I plugged it in and left it to finish downloading, but when I came back it wouldn’t turn on. It’s now been charging for around 4 hours and still will not turn on (whilst charging or when I disconnect it). I’ve tried removing the battery and putting it back in, but it still doesn’t work. The red indicator light flashes or stays lit when it’s charging.

I answerd you in this other topic:
