[Q] Help...Xperia ZR not powering on.

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.

Help flashing

Hi, i flashed the CM12 rom, but it was very buggy so i decided to go back to pac-rom. But the cm12 rom switched to a cm bootloader, which sucks since i cannot flash rom from there.. But phone is working and im trying to flash with flashtool. Its waiting for flashmode, phone is off, i press the volume down and insert the cable, but nothing happens, i have installed drivers successfully. What happens on the phone side is that i see the sony logo, then the battery/charging. Help?

If the battery charging comes up, looks like the volume down button is not being recognized, check if you are able to get the fastboot/bootloader mode. press and hold Volume Up and connect usb should see a blue led, if so try flashing boot.img from any other rom, if possialbe system and userdata. you could try this ASOP ROM to start http://www.blinkenlights.ch/ccms/android/yuga-l.html

Anyone else? i get into cm bootloader, but there is no option to flash new rom..

[Q] Flashing issues

Hi, i have CM12 rom, but it was very buggy so i want to change back to pac-rom, thats not so easy turns out. twrp recovery was removed with rom and im left with cm recovery which has no option to flash rom. So im trying with Flashtool, i choose stock firmware, flashmode, its waiting for flashmode, i press vol down and plug in cable, i see sony logo and then battery icon but it doesnt enter flashmode. So how can i fix this? I Just want back to pac-rom, where people can call me without my phone rebooting etc.. Maybe i can try installing dualrecovery and flashing pac-rom via that? Pls help

[Solved]Bootloop

Hello my name is Bob and this is my first thread, unfortunately its me asking for help so not really a great start.
Getting to the point however, i installed a 3rd party app which allowed me to change the font of my Sony Xperia Z1 after i did this and it reboot my phone it got stuck in a bootloop.
When i power up my phone i get the following occurences Sony Xperia start screen followed by POWERD BY android and it reboots the phone repeating the process.
My phone is ROOTED, my bootloader is LOCKED, i do not have RECOVERY.
C6903, stock rom
Things i can do with the phone;
Plug it in my laptop and have it show %charged
Plug it in my charger and have it show %charged
Go into fastboot*bluelight* by pressing the volume up button and plugging it into my laptop
Shut it down by pressing the power button + volume up
Go into bootloop by pressing the power button
Edit1: I do not care about wiping all date if necessary or possible!
Edit2: Flashtool, usb debugging off
Edit3: Currently using Sony PC Companion to force re-flash stock
Edit4: Finishing using Sony PC Companion software update, updated to version; 14.6.A.1.236-R2D, currently booting up phone*purple start screen*
Edit5: Phone is working, lost root
Any help would be much appreciated!

Well my opinion always when you root your phone install Recovery
Very important for something like this
*.Font Changer app don't work on Xperia Device (maybe because of Sony company)
If you wanna still want to change fonts there is thread about zip fonts to flash it on your device (it's working great)
And if you got bootloop again just flash rom Through flashtool no need to be USB Debugging on ( just enter flashMod and flash Rom)
And it's good to hear you solved the problem

Hard bricked xperia z1 - please help

Hi Guys,
I really need your help unbrick my Xperia Z1 C902.
Here's what happened:
I tried to flash a custom rom that wasn't compatible VIA AROMA ( I had MiUi 7 custom rom ) and it is now dead. It won't boot. No sign of life. No Vibration when pressed vol up+Power . Hard reset ( via sim slot ) has no affect on the Phone. No recogniztion to USB on laptop ( tried other USB cables as well ).
I have left the phone be charged overnight assuming the flash took a toll on the battery ( it was about 30% when I flashed the phone )and in the morning there was a red LED. Assuming the battery had enougfh power I tried to turn it on, connect to Laptop, Fast boot mode, flash mode but with no luck.
Day2:
Left the phone connected to the stock charger for about 20 hours or so.
No LED lights. No vibrations. No sign of detection on the laptop.
Sony Companion will not detect my phone via fastmode as well.
This phone is out of warranty so I was hoping you can help save some bucks before I take it to the Sony centre.
I looked through XDA all day but nothing has helped me bring my phone back to life.
EDIT:
I have downloaded India Stcok ROM via Xperifirm and tried to flash it but the flashtool does not detect the phone. Fastboot and Flashmode both does not detect the phone. Strange thing is, when I plug the phone to laptop holding the Vol down button, a red LED blinks for few seconds but the fastboot does not work ( as my phone has bootloader unlocked )
ADB does not work - No devices connected.
If there is anyway I can flash or install TWRP recovery ( or any for that matter ), I have the old working MiUI rom in the external SD card.
I will owe you a beer or two and a dinner if you 're able to bring my phone back to life. Please I am desperate.

Hi.
You have flashing led that means there is some hope first press and hold hard reset button for 15-20 seconds under sim cover then realizes it. Now plug in charger and dont touch the phone before 4-5 hours. Let it charge even though red led comes on.
After that disconnect your phone and don't turn it on wait for 5 minutes.
Also do check if the flash tool drivers are properly installed (window 8 and newer needs you to disable driver signature enforcement) use flashtool version 0.9.19.0, dont know why but this version works best for me.
Flash *.108 firmware (available in xda) also do always check hash after downloading.
Now try to flash the firmware as normally we do and hope for the best. This method worked fine for me many times.
Good luck..! [emoji111]

The flashing Red LED is bringing back some really bad memories of my own Hard brick. Try what kathanpatel suggests first - holding the reset button down.
Are your symptoms identical to this?:

There is a link to a post with instructions on recovering from the hard brick. Good luck.

The red button in a sim slot won't have any effect unless your phone is connected to the charger (not computer). Connect the charger, press and hold the red button for about 10 seconds until there is vibration. Then immediately push and hold the power button for a few seconds.
