hi guys, yesterday i did some flashing of roms just like i do almost every day or so, and i didnt like the rom(flyme rom) i flashed so i just tried to restore the previous rom which was the existenz rom .... so using TWRP, i put that to restore and i went to eat something but after a couple of minutes, i went to my phone to see if it was completed and it was powered off by itself... ( the phone was not completely charged but it had at least 50% of battery so i dont think battery is the issue here).....so after that,i powered it on and it stuck in a bootloop so i realized that the restore wasnt successful.... so i went into the recovery and i did a factory reset and i tried to flash another rom cm11 based (that i had been using some days ago) and the flashing was successful ( with gapps and ssu...) so i rebooted but nothing.... my phone powered off as it should but when it powered on, sony logo appeared (as it should) and then it suddenly powered off again..... i couldnt even enter the recovery cause it immidiately turned off 2 seconds after sony logo appears.....so i went into fastboot mode and i flashed a kernel of cm11 just to be able to enter at least the recovery .... successfully flashed boot.img but again couldnt enter the recovery...the same as before.....then i realized that if i tried to power on my phone while it was charging ( wall charger) it could boot and even enter the rom but still after some seconds it immidiatly powered off by itself for no reason...then i didnt know what else to do so i had a last chance.to flash an ftf....so i flashed one successfully using flashtool and the same problem again..... then i flashed another one ( older ftf ) but nothing..... then i tried to charge my phone until full ( i could see in TWRP the percentage) and then i powered on but the same..... however it did open whithout charging ....but again after some seconds it powered off again.... so i went in TWRP and i left it there open all night to drain all the battery ...and i noticed that it drained until 1% and then it took it about 1 hour to power off ....i mean it was on 1% with screen on for more than an hour.... so i think that the battery has to be reseted or something..... i dont know what to do.... i have unlocked bootloader, i have no warranty , and i dont even know what is causing that so please if somebody knows something about that tell me....:(:(:(:(:(:(:(:(
(btw before all that happened, my battery was fine...i could spend many hours with screen on.... i had not noticed any damage to the battery or something)

Somewhere in Oz...
A partition or partitions could be corrupted, and formatting is the only way to fix that. Not sure if flashtool formats before writing images - so..
1. Fastboot a kernel (boot.img) .
2. Boot into recovery and format EVERYTHING, including /data/media.
3. Power off phone.
4. Flash an ftf.

Good luck:thumbup:
