What to do when stuck at bootloop? - Xperia Z Q&A, Help & Troubleshooting

Hello,
I am waiting for my handset replacement and meanwhile collecting all the required Rom/addons for the same. I have decided to flash DoomKernel after I'll get my handset and flash KA03 rom. I have a doubt, if I flash the rom and end up in a boot loop after that how would I go back to stock. I know I need to flash .ftf using flashtool but how would I go into flashmode when phone is in a bootloop? and we cannot remove the batter as well...

You have to press vol up +power for 15 seconds,you will feel 3 vibrations,this will shutdown the phone like removing the battery.

You f***ked up your phone so no more recovery.
You have 2 choices:
1-do as i say before.
2-wait 10 years maybe the recovery will show up somehow

Press the power button for about 10 seconds first, when you see the screen turn off, that's when you press volume + power button

Please try fastboot-mode. Can you enter it? (press vol+ and plug in usb cable while pressing)
If so just use fastboot (tutorial: forum search) and flash a stock rom...
I think it's only a "softbrick" - no big deal to solve.
Good luck!

Here you'll find a lot of information to help you out with your xperia z, too.
Use fastboot mode, flashtool and a sony stock rom to solve the problem. You won't need a working recovery.

You have to flashtool back to stock... Here is the tool.
Download stock ftf and flash it.
Edit: Here is the tutorial you need.
Shut it down by holding volume up+ power for 15 sec before the battery finish.

When using SUS, it will tell you you already have the latest software, but you can continue the process anyway and reflash the device.

Hold down both volume buttons and the power button for 20 seconds, then it should boot!
try recharging the battery as it might be a wrong battery reading the 80%

Hi Zohaib,
nice to see you here. Hope you will come up with some good roms.
good luck with your bricked device
Did you play with TA partition?
Did you unlocked the bootloader?
Ps:emma is only for unlocked bootloader so it wont work in locked bootloader.

If bootloader is unlocked it should be easy to fix, if it's locked it also should be able to be fixed if it's a soft brick is it locked or unlocked?

[sos] xperia z not booting

Hey guys! My Z has been awesome these past few months and w the recent 4.2.2 update, its been PERFECT. I finally rooted it last week and installed CWM for locked BLs. However I haven't been able to boot to recovery so I downloaded an app called Quick Boot (Reboot ). The thing is, when I selected "boot to recovery", my screen went black and now I can't start my phone!
The LED also does not light when plugged in, and I've tried every possible button combination with no results.
Please help! Thanks!
Try holding power and volume up. You should feel a vibration and the phone should restart.

You could try flashing a stock rom with no wipe with flashtool.

Just grab one of the generic 423 ftf available in the general section. Make sure you follow part 6 of the tutorial regarding keeping your data.

Your phone doesn't need to be booted to use flashtool. Just give it a try. If it doesn't work, you could try doing a repair with SUS - http://www.sonymobile.com/in/tools/update-service/
As for that app, I doubt it has bricked your phone. Any app that has a 'reboot to recovery' option will not work on our device as we do not have a recovery partition. There is a fix for this in the original development section that allows 'reboot to recovery' to function properly.

This is very strange. When you held power and volume up, how long did you wait? You have to hold them for around 15 seconds IIRC.

What the hell, I'll try help. If you're in windows 8 you need to install the fastboot drivers booting without driver signing, what os are you on? if you need more help reply or check my profile for my skype user.
Try to push pwr + vol down to enter into flasboot.
You should also try pwr + vol up until the phone vibrates 3 times. That's a hard reboot.

fastboot is vol up + usb while device powered off. FLASH mode is vol down. What exactly do you get from the device? Any feedback at all? Backlight? Vibration?

I have come across same problem a month before. Now just relax, it is easy procedure.
If your phone is struct in the loops, then you have to wait until battery gets completely discharged, (because you cannot remove the battery to stop the loop) . Then put your phone to charge for about 1 hour. NOW DO NOT TRY TO POWER UP YOUR DEVICE OTHERWISE YOU WILL HAVE TO AGAIN WAIT TILL COMPLETE DISCHARGE. Now repair using SUS OR PC COMPANION, OR YOU CAN TRY FLASHTOOL IF YOU HAVE FTF FILE.
