Please provide some details about the situation you are having. Did you unlock the boot-loader before flashing the kernel?

I flashed it through CWM

When facing with this problems, it is recommenddd to immediately flash stock firmware upon shutdown of device. Use flashtool and flash ur device's stock firmware to your device quickly

Which Williams kernel? Cm ones cannot be used on existenz
Sent with the XDA Premium Application for the XPERIA SP running CM11s

I 100% guarantee it was the stock based kernel. Anyways, as it is still early in the morning here, I am just gonna write down some steps here. 1. Flash CWM for locked bootloader
2. Restore previous backup
3.See if it works?
4. Factory reset if it works
5. See if bootloader unlock allowed changed from yes to no and if yes unlock bootloader
6. Flash existenzultra

Just cannot update :/

I bought a xperia Z. its shows an update on the phone but i just cant install it...it fails everytime. and even if i try to do it via pc companion. it says that the phone is running a modified firmware that cannot be updated.. So please if anyone can guide me on this..i just want pure stock from where i can install ota whenever it shows up. thanks.
Hi there Sir, try downloading the ftf of the firmware you want and then flash it through the use of a flashtool Sir
Yea, use flashtool to flash to any stock rom ftf, rmb to change the country in sony companion to your country so that you get the correct updates off your countries' telco
Thanks a lot guys.

I think that app should be patched directly on device you want to install it. Or maybe you had installed "normal application" on xsp first, didn't work, patched and tried to update? I had a problem with gta:sa where obb files blocked me from installing patched app. Deleted it and it worked just fine.

There are threads in dev section. I think custom fw is worth trying as well. Even better than stock. I didn't want to dabrand my phone when i got it and later go away from stock rom, but now i'm sure cfw are being done to be greater than stock. There you can find detailed instructions
