Hi,
Yesterday I tried to install a ROM (Romaur) on my Xperia Z and i don't know how i came to thit situation:
The led is blinking in red when charging.
I cannot enter the flashmode (green led doesn't appear)
I can enter the fastboot mode (but my bootloader is locked so I can't do anything)
If I try to turn on the phone it vibrates but nothing else happens.
At first i thought it was a battery problem, but i've been charging the phone all night and still the same.
Thank you for your help.
EDIT: Solved using Sony Update Service. While flashtool didn't recognise the flashmode (I don't know why, it has always been working) this software did.
My Xperia T (Sony Stock 4.3 with locked bootloader)died the other day - think it may have been battery related as my son was playing some games on it . Since it shut down it will not boot properly . When I tried to charge it - I get a red LED in top left hand corner , the SONY logo , then after a minute or two I get the phone symbol with a yellow exclamation mark . I have left phone on the mains overnight - no difference - it just loops as mentioned. If I try a repair thru PC Companion or Sony Update Services it fails to update although it does detect phone and start when I press power + volume down , I get the green LED as well . I have tried FLASHTOOL , this appears to work as I can put the phone into Flashmode , and flash the ftf file . I have tried different ftfs (4.0.4, 4.1.2,4.3)The logs says flash has completed and that the device should be disconnected and unplugged . Once I switch on , it just loops as mentioned - SONY - Yellow Exclamation . If I run SONY Update service it detects that I have latest OS - Android 4.3 installed so something is accessible . Just wondering if anyone knows how to recover to factory defaults or any other tools to recover the phone . I cannot access fastboot (power + volume up ) does not work . I also had a CWM recovery partition installed(previous ROM Miui JB for locked bootloader ) but this is no longer accessible . I have also disconnected the battery and left overnight .
Any help much appreciated

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:

The phone rebooted and Sony logo came on but restarted twice and not it can turn on again. Just red light turn on and off when charger is connected and when I try to turn it on too, the green light blinks and phone vibrate but won't turn on. Fastboot mode too won't stay on because green light turns of after few seconds. PC can't recognize the phone. Please help me. I have tried using all keys to try to turn it back on but no luck. Help guys
