today i tried charging my phone using a 5 V 2Amp rail on a pcb from a monitor!.
I connected the usb and shorted the ground and Data + pins on the usb connector to start the charging.The phone was charging but the battery dropped form 70 to 69 % after this i disconected the phone and rebooted it the battery was 93%.
Then i pluged the phone to a 1.2 A charger that i was originally using (Not the charger that came with it! this was a Nokia charger) and the phone would not charge.
After a reboot i saw a meesage that one app got uninstalled.
I downloaded and flashed Carbon Rom 4.4 the one i use for about 2 months now.And tried again (i thought that would replace the uninstalled app the probably messed up the charging.).
Then i hooked it up on the pc and it will not recognize the phone normally in fastboot or flashmode.
The plus is the phone works fine and when plug in the charger when its powered down it boots.
Thus i dont think i blew the charge controller on the device.
But it wont go into recovery after the flashing of the rom
I run Carbon Rom KK (4.4.2) Nyan kernel UBL And i haveo nly about 60% of battery left to save it.
