I got the dreaded GSM bug on my E (running CM10). The battery was down to 7%, and I was being told to sleep. I did the foolish thing and turned it off, hoping I'd turn it on tomorrow and flash stock. Next morning, the phone didn't turn on; the red light issue. I managed to turn it on, but soon as it turned on, it complained about lack of battery and turned off - the battery symbol didn't say that it was charging, it just showed an exclamation mark. When the phone turned off, it didn't turn on; I never even got the red light back.
It's charging right now (or so I hope) with a 2A Nexus 7 charger and Sony's stock USB cable. Even after charging for about two hours, it still doesn't get a red light. I can't take it to Sony cause it has CM10 and I can't flash stock as I can't get it into Flashmode.
Help me? Please?
