So much fail.
Do not use vroot, it sends your imei number to an ip address in China.
Also, unlocking your bootloader on 4.2 will break your camera, it clearly says so on the Sony official site about unlocking your bootloader.

Now, the solution.
Restore your ta partition.
Use pccompanion to update to the latest firmware
Unlock your bootloader again
Flash a custom kernel of your choice
Install super user app of your choice

.534 is 4.2 FW. the camera will not work with an unlocked boot.

Follow the advice I gave above

yeah..!! i have done it.. thanks :)
but i have unlocked it in 4.3 does it make any sence by unlocking the bootloader in 4.3 and i didn't get any recovery mode... so.. i downgrader to 4.2 and installed the dual recovery as the thread says it needs .534 firmware to root properly...

I have to ask

Why are you unlocking your bootloader? What have you done it for? You do not get a recovery mode just by unlocking the boot, you have to flash a custom kernel with recovery in it

You either do all the downgrading and install dual recovery if you have a locked bootloader


OR


You unlock your bootloader, flash a custom kernel with recovery and install super user app

there is no need for both approaches and that's why you are getting problems

i unlocked the bootloader... i didn't find any recovery after unlocking so i followed the xzdual recovery process... but is it safe to flash a custom kernel.. :confused: and by installing only recovery without kernel does this doesn't help..

Why did you unlock the bootloader? What did you want to do with it?

You can not install a recovery without a custom kernel, xperia devices have no recovery partition, it can only be installed by pushing the ramdisks to the system partition or by flashing a custom kernel.

Please follow the advice I gave several posts ago.... that is your solution.

Then spend some time reading up on xperia device flashing.

1) Xperia devices have no factory recovery or recovery partition
2) Unlocking the bootloader is the fastest and easiest method to root and get recovery (If you are allowed to do it)
3) If you cannot or do not want to unlock the bootloader, then go through the downgrade, root, dual recovery process...

ok... can we get the recovery by unlocking the bootloader by official way??
and i saw a doomkernel... by installing it in fastboot can i get the recovery mode with locked bootloader or i should seperately install the recovery..?? :rolleyes:

When china takes your imei, don't they use that and put it on their "clones" so the phone they make work with calling?

Greg said fifteen times - follow his guide for here.

Yoy can't flash custom kernel especially not fastboot custom kernel on locked bootloader.

Whole purpose of unlocking bootloader is to flash custom kernel.

You are confused with all this informations, I would recommend that you read few things here on XDA to understand terms and other things.

You could seriously damage your device with just one wrong step.
