Xperia Z Dead , After Flasing TFT

[Cuculuz]

Hi xda people .

I need some help with my Xperia Z , yesterday i flashed a Rom 5.1.1 slim official and gapps .
after the flasing was finished via phils recovery and gapps zip flashed , the phone rebooted like normal .

it was loading the apps and stuff to be ready after the first install , then the phone went burning hot and restarted ( just to be clear the phone was not connected to a usb and it was not charging ) , and after that i have no success in flasing a stock FTF with flashtool or repair with SUS.

the phone Fasboot still works / Flash Mode works / but when i flash a stock system the phone dont boot past the sony Logo , it switches on and straight after the logo i can see the screen flash 2 times and it switches off again and restarts
pressing the Vol UP and holding the power button down 20 sec have not helped also .

can some one please help me :crying:

Firstly, make sure you cool down completely your device, after that give a try to fastboot flash any rom you desired. Maybe your phone is too hot and it doesn't boot-up/work?

I got the tft flashed , pure v 3.1 lollipop 5.0 2 . But the phone works only on a charger , if i dont the phone starts boot looping , battery shows 89% , if i open camera or any other power demanding app the phone dies again , cant do a battery test phone restarts .

small update

Battery level is at 100 % ( Green Light was light in the morning ) Phone turns off after removing main charger from wall / / phone dont turn on when using regular usb2.0 cable and connected to computer , ( using usb 3.0socket with extra power ) phone turns on then .
When Phone Charge level is at 80 % phone turns off again , then i went to recovery ,battery level is shown 100 %, restart system again need to connect to wall charger again and switch on phone, after boot when when system is loaded to desktop phone show charge level 80 % and switch off again soon after that.

battery is calibrated using a app from play store ( now the phone holds the charge but still reboots when the charger is not connected ( Need to plug in the charger again to boot the phone back up to desktop.
remove cable again , after about between 3-10 mins phone is off again , try to turn it back on cant wont go past sony logo starts boot looping , connect charger again all seems good until removed again .

Battery health status is shown (good)

Flashing any other ROM or original TFT for android wont help
the issue is still there the phone dont boot to desktop unless a power cable is connected

now switched on the phone again with 100 % in the battery , wifi and other stuff switched off
made a test phone call to a friend all working fine no reboots , but why on earth the phone switches off again when it reaches below 80 %. or when i connect to a wifi or mobile network try to make a picture instant reboot if no charger is connected.




im out of ideas :silly:
