Use flashtool and any stock ftf. If flashtool fails flash some partitions- flash system only, then data partition.

Hi there!
Do you have flashed GB Kernel fitting your GB Rom of the Backup you have restored?? You need the fitting kernel.
Download Fastboot oder Flashtool, get the kernel img an flash it to your phone.
Bye an good luck!
What ROM do you have installed then currently?
Install the proper kernel also according to this.
Full stock .ftf firmware files should also include kernel.
yea the firmware's iv been flashing have the kernel in them. I think i damaged the bootloader coz al the flashing was succesfull but the ray just wunt boot into android so damaged bootloader. Anyway i gave up and its in for repair lol.

need help with this situation

ok so when i was trying out a custom GB Rom which requires flashing of stock GB,i forgot to flash the stock and flashed the custom GB straight from my ICS 4.0.4. it got bricked and i used the sony update service[not pc companion,in case you don't know] to fix the brick and it returned to stock ICS 4.0.4 . After that,i have forgotten that stock ICS does not have root access. so i went to flash other custom ICS ROM straight away cause i'm used to flashing different custom ROM and now it stuck at CWM. Now it has been officially bricked,the only thing i can access is CWM. what can i do now?? i've tried sony update service and it says i have the latest stuff and i also can't flash any rom since i have no root access and i also can't flash stock ftf file since usb debugging and stuffs are required to flash stock. so what can i do now??
thanks in advance
PS: I've tried using the file called Unbricking xperia 2011 as well,doesn't work
Edit: got it back,i flashed 2.3.4 ftf. i guess the previous ftf i flashed was corrupted
flash a 4.0.4 FTF file using flashtool

Stock kernel for MM 575?

Hi,
I flashed a rom and several other files to update my xperia Z2 to the latest stock version (575). However, I didn't realize that my phone had the bootloader locked and I mistakenly flashed a custom kernel (abricot kernel). Now, my phone won't boot. When I press the switch it vibrates and does nothing. I am guessing it's because of the kernel.
Now, the "hopeful" news is that I can access fastboot mode, therefore I was considering two options:
1) flash the stock kernel image (however, I don't know where to get it from)
2) unlock the bootloader (I need to find out how to do it).
Do any of you know where to get the stock kernel from?
I'm open to any other third option you may think could help me unbrick my phone.
Thanks in advance
What about flash again stock firmware with Flashtool, but mark options Wipe data and cache?
>>Flash the same .575 stock ftf without wiping the data through flashtool.
>>Everything will be okay.

Trying to Downgrade Firmware

Hi,
I have been trying to downgrade my Xperia Z2 (D6503) from android 6.0.1 to 5.0.2 and even 4.4.4 in order to root it, however everytime I flash the previous firmwares, the device gets stuck in a bootloop.
Does anybody know how to avoid this problem?
You need to wipe data after downgrade. Otherwise device will bootloop.
So first backup the data and then you can flash 4.4.2 Kitkat firmware using flashtool with wipe.
use Flashtool
