I need to confirm before submitting to Sony Service center.
Day before yesterday, I check my phone in morning, It was powered off. I connected the charger & My Phone is not powering on. Not even the LED is lighting up. I let the phone over the charger throughout the night but still no response. Unable to connect the PC in Flashmode / Fastboot mode.
Just noticed that, if I connect the phone to the charger without battery the LED is lighting up. If I connect the battery to the phone the LED powers off. Is it normal in our Xperia ZR, that the LED will light up if connected to charger without battery. Or My Battery / Phone is dead ?
I am in Locked Bootloader
Any suggestion would be helpful. I am asking It because I have rooted my mobile. I am trying to flash clean stock firmware before submitting to Service center.
Did you recently flash a custom ROM? If so, did it boot before this issue? When you press and hold the power button, does the phone vibrate? How did you try to booting into flashmode and fastboot? As a reminder, for flashmode, press and hold the down volume key and plug in the cable, for fastboot press and hold up volume key. Try both of these while connected to your computer with Flashtool open, and check if you've succeeded. If yes, go ahead and flash your stock ROM, problem solved.
If you didn't recently flash a ROM, or none of the steps detailed above are working, it is probably a battery issue, or a kernel issue (some custom kernels have a bug which allows the battery to completely drain, making it unable to charge again). Try buying another battery and check if it works.
After all this, if you still cannot flash the stock, your only option is Sony Service, and even they may not be able to do anything. Plus, if they get it working again, you may not be able to claim warranty if you're on a custom ROM, though you might get lucky, since your bootloader is still locked.
Hope this helps.

I just rooted & on full stock rom. It was working fine all day. Nothing major is done on my phone. No vibrate while pressing power button.
I tried connecting flashmode & fastboot mode by pressing up arrow(and down arrow) while connecting to PC. Device is not detected in Device manager as well as in flashtools.
Just now only I returned home after submitting mobile to service center.

Then it was probably a battery defect. If all you did is root, then you have a reasonable chance of getting it replaced under warranty, mainly depending on the mood of the service inspector.
i was installing eXistence rom v3.5.0 and while installation was about to finish as my battery was low the phone went off and since then wont turn on.
when i charge it the red LED turns on and when i remove from charging the led stays on for a bit and then goes off ..
and phone wont go into flash mode .
please help urgent :crying:
are you able to get into fastboot/bootloader mode (+ Volume key and connect usb), if so try this http://www.blinkenlights.ch/ccms/android/yuga-l.html do not install gapps yet, make sure you can charge your battery first.
Do a fresh installation with flash tool using ftf file. u have soft bricked the phone. but you are able to enter into flashmode.
hope this works!!
Edit: if you see a led light on the phone then i think you can enter into flash mode. if you are on windows 8 there may be driver issues of flashmode. what happens when you try to connect in flashmode??

Hello,
I want to know how i can charge my battery in fastboot mode , my battery is below 15 % and my phone and i have to do a factory reset with the 3 button method.
Thx
You can't charge battery in fastboot mode.
Turn on device by pressing and holding power + vol+ and charge it in recovery mode.
Thx, but i cannot stay in recovery mode , phone shows recovery mode for 1 sec than it go's to fastboot
It's a bad sign. Seems like kernel panic. Anyway, even if you will charge battery, you won't be able to flash firmware.

Hi
my phone wont boot at all. Connecting to charger gives continuous red flashing LED. Tried different key combos to reset/reboot. Nothing helped.
When i connect my phone to PC, Flashtool show phone in flash mode. Have also tried flashing different kernel and recovery from fastboot mode, but that is also not working.
Any help is appreciated.
Thanks
I Just flashed .253 firmware and it works now. maybe OTA messed up? Can someone confirm this?
Hi guys and girls from xa.
I have phone which powerbutton is not working, so I ask how do I boot my phone?
I think it's not in USB debugging mode coz I can't find it whit adb, how about fastboot?
I just need it to boot that's all thanks if u have time to tell me.
Yours. Jani
I don't think you can. To enter recovery (adb) or fastboot you need to use the power button too. Maybe you can try to hold one of the volume buttons while plugging the charging cable. It might get in download mode or safe mode or something
EDIT: I just tried it myself and it doesn't work. It seems you need to find a service center or repair station to get the button fixed
