[Q] Xperia Z wont boot past "sony" - Xperia Z Q&A, Help & Troubleshooting

hello all, i have a sony xperia z (rooted) but now it wont boot up!
first of all it had been rooted for a while now and everything was fine, however i tried to unroot following a tutorial on youtube using sony's update service, it got to the installation then an error came up saying it had failed and to retry when fully charged (phone was over 50% charge) since that the phone wont boot up, it will get to the sony screen then just power off again, sometimes the led will flash very quickly in green, flash mode? not too sure..
i have no idea how to fix it so any suggestions would be awsome!, thanks, Jordan

Cheers bro! after waiting for the downloads it literally took me a matter of minutes to flash the stock .ftf

Easiest way to uproot is to use pc companion, glad it's sorted

Think you will find Seus / PC Companion wipes data where flashtool doesn't

Yesterday,I rooted my Z with b4nary's method with locked bootloader.I flashed cwm recovery for locked bootloader.All OK.
When i tried to flash krappabel's mod for black statusbar and buttons I screwed it.They dissaperead.
I didn't make a backup.Nothing. Installed the iphone touch buttons somehow(because no back button)
Then I tried to manually change the SystemUI.apk.Succes.
When i tried to change the permissions my phone reboots and doesn't let me.
Any solution?please please please! :crying:

dude i had the same problem, download this
http://www.sonymobile.com/gb/tools/update-service/
turn off your phone and put the micro usb in your phone ( dont connect to pc yet ). start the update service and choose your phone ( normal xz , not japanese version!! ). it will say u need to press volume down while phone is off and after u keep pressing down put the usb in your PC. IT will detect and wipe and install stock rom.. ).. tell me if it works
Do you have unlocked bootloader??
If yes use this http://developer.sonymobile.com/201...ocked-xperia-smartphones-video-beta-download/

What's the error cause the image is unreadable.
When you connected the phone in flash mode(vol Down+usb) did you installed the drivers?
Usually when you click on flash with flashtool and you select the firmware,you have to wait till the pop up tells you to connect the phone.

I bricked my XZ :(

Please help guys. I tried flashing ROM using the instructions on the front page for locked bootloader and my phone froze on formatting /system, I restarted phone and it is just stuck on Sony. I have tried holding power and volume up it does nothing except restart the device. My PC won't recognise it to do any repairs. Any ideas?
Keep pressing vol up + power for 15 sec till the phone shutdown.
Use flashtool to flash a stock ftf firmware.

It just ends up vibrating for three times and restarting back to Sony screen?
Weird this should turn off the phone.
Is the phone plugged to a usb?
Sent from my C6602 using xda premium
Ok thanks I have it turned off now. How do I flash with it off with flashtools?
Download flashtool from development section,and an ftf stock firmware.
Put the ftf file in flashtool/firmware folder.
Install xperia z drivers,you find it in flashtool/drivers
Click on flash,choose the ftf and wait the the pop up telling you to connect your phone by holding volume down and connecting the usb.

I don't know if there is an easier way cause i didn't tried the recovery available.
All you can do is doing all steps again and install the recovery than restore your backup.

ok so i was stupidly messing around with my fastboot cwm interface menu`s
and i decided ,somehow that it was a good idea to try and install the jellybean 4.2.2
firmware on my device so i entered the install from sdcard menu without even thinking much about it i located the .zip file and installed it and clicked reboot and then absolutley nothing but the boot vibration went off and the screen stays black and it is stuck here . so i used to old powr+ vol up for 3-15 secs and waited for the double vibration and still nothing happens .so im stuck.
sorry for the long post but i`m in a panic as this phone is fairly new about 1 month old and i had already rooted and unlocked boot loader on it so .i hope the info helps you to help me
please respond asap :fingers-crossed:

Sounds to me like you haven't flashed the kernel required for 4.2.2 (I am presuming you were on a stock/custom Sony ROM before)
If you flash 4.2.2 you also need to flash the kernel specific to the ROM you've tried to flash using fastboot commands.
To do that you need to have the correct XZ drivers installed, and have adb/fastboot working

The phone working normally like before.
Then I charged the phine whole night.

I am 99% sure it has water damage and is broken.
However, if you have not unlocked the bootloader do a software repair using PCComapnion.
If you have unlocked the bootloader or that does not work, flash a stock FTF using flashtool. Make sure you wipe everything.
Hve tried flash using flashtool and wipe anything but nit work. Still bootloop.
But I can enter recovery mode and no restart almost 30 minutes.
Will try using PC kompanion. Will rrport again later..
Eh but my device is unlocked :banghead:

But doesnt problem if enter recovery mode.
My phone has anomally :
- If I inserted the battery the phone just turn on but in bootloop condition
- If I take out the battery and plug in the charger, the phone also turn on but only sony logo after that restar again and again and again
I think have problem in electricity circuit in my phone

Try flashing a stock FTF using flashtool.
Get the FTF from the all in one thread in the Q&A section and download flashtool from the first thread in the dev section
EDIT
Are you sure PCCompanion flashed your phone? If it did you should no longer have recovery.
Nah.. I mean that recmod no problem no restart. Before I flashed stock FW and relock bootloader.
I just confuse why my phone can boot to recmod and no problem but cannot load the OS

I know what you mean, but if you did repair your phone and follow the advice I gave then you should not have recovery.
Did you follow my advice? Did you follow my further advice and flash a FTF in flashtool?
