Phone won't charge turn on . No recovery No splash No download
So my phone is flashed with cool rom running NXT kernel , it had been running fine for the last few weeks. Yesterday the battery ran out so I put it on charge for a bit and rebooted it hanged at the boot animation. Left it to charge some more but it only displays the grey empty battery. I know it's detecting the charger because when I unplug it stops cycling the battery graphic. I can't get into recovery and if I try getting into download whilst plugged in it says battery too low.
I figure the charge board is dead? I have ordered a desktop charger and another battery to charge externally with the hope of returning to stock and sending back to Samsung . I have 10 days before its a year old so a bit of a race against time. The phone had been fine til the last OTA update in the uk which made it really sluggish this is the only reason I had changed the rom. Any help over advice will be gratefully taken on board.
