[Q] XZ does not boot anymore after CM 10.1

Hi!
I just got a Xperia Z from a friend who try to install CM 10.1.
Apparently the bootloader is unlocked, CWM installed. And after the installation of CM, the device does not boot. Sony logo appears after a press on the start button and it turns down instantly.
What did I already try:
- Flash of two official roms with flashtool. The process stops after the progression bar is one fourth filled but nothing tells that the processus failed. But same issue always here, does not boot.
- Re-locked the bootloader with BLU (flashtool) to restore the phone with using Sony updater service : I have an error : "No loader found on this device".
Need your help please

Have you made a factory reset and cache delete before flashing CM? I make this mistake often but with flashtool I can always install back the stock rom.

I'm pretty sure he did a wipe data and wipe cache before the installation.
Flashtool does not repair my phone after a flash of the stock rom, do not know why..
What can I do ?

Do some research about how fastboot works to flash the official XZ kernel through fastboot

Maybe try to flash the CM kernel and go into recovery and flash a other Rom.. I'm not sure if it works but haven't better idea.

This is called a bootloop. All you need to do is press VOL UP + POWER, then connect your phone to your computer in flashmode (connect USB while holding VOL DOWN button) and flash .534 using Flashtool

Yep, just Hold Volume Down, connect to PC and flash a Stock FTF.

No just go into recovery, flash the monxdified rom zip and then clear cache and dalvik. I have done the same thing and it works perfectly fine. You can flash any 4.3 rom in this way, as you are on the same firmware.

Monxdified, iHackers and all stock based roms don't need a custom kernel (that's why you don't need to be bootloader unlocked to use them)
Just go into your recovery flash the zip. After the zip is flashed you will get an option to clear dalvik and cache.
It is always recommended to do a factory reset before flashing a custom rom, as it might misbehave. You can however try it without factory reset and then if you see that it doesn't work properly just do a factory reset and flash the rom zip again.

I can go into the cwm recovery with the "UP" volume key.

I guess that you have flashed a custom kernel and tried to make a normal boot ...Xperia ZR won't boot normaly when you flash a custom kernel!!Just enter to recovery mode,flash root files,and then flash the stock kernel and the device will boot normaly

use flashtool and flash a fresh .tft

Before doing anything ... Remove your device's back cover and push the small button for 5 seconds...
Your device will vibrate 3 times.. After that wait 10 seconds and switch on your device...
Try installing a new recovery... Try the doomlord's advanced system recivery or doomkernel..
After installing the recovery try to flash the zip again..
If nothing happens ... Try a stock rom...
All the best !!! Hit thanks if it helped ...

Follow these steps... firstly copy the superuser zip file into your external SD card.. Be sure that your device is atleast 60-70% charged..
1. Flash a stock ROM via flashtool in flash mode.
2. when flashing is done... flash the recovery u want from flashtool in fastboot mode.
3. switch ON the device and enter into the recovery ... (CWM recovery)
4. install the zip ... wipe cache and dalvik cache.. and reboot..
try this recovery..

Hello,
Welcome to XDA.
To better assist you, your thread will be moved to your device Q&A forum. The experts there may be able to help you. Good luck.

You must flash full stock ftf file.
Flashtool says you must be rooted because you dont have your bootloader unlocked!
