Which country are you from?

No need to do any of that if your boot loader is unlocked. Just flash a custom kernel.

For downgrading firmware version? That's not really a good choice, flashing with a tft file is clearly better, flashing a custom kernel can hard brick your phone, avoid your warranty and can't be restored with SUS and PCC...

No, he asked how to root. If he has already unlocked the bootloader then the simplest way to root is flash a custom kernel. Warranty is already broken and what is the point in unlocking the bootloader unless you are going to flash a custom kernel anyway

Yeah but flashing a custom kernel is not necessary for having root on the latest firmware.

No its not, but its the easiest way to get root if you have already unlocked.
And please tell me the point of unlocking if you are not going to flash a custom kernel.
Its harmless as long as you flash the correct kernel. It carries the same risk as flashing anything.

You have downgraded in order to root then to do an OTA upgrade back to .257 if I am right.
In which case, do not worry that the camera does not work in .534, just root it, and upgrade OTA.
Then try the camera.
EDIT
Also you need to clear the data in all camera related apps

This was the first ROM I flashed on my T and as far as I can remember it ran perfectly. Which ROM were you coming from? Unless you're flashing a nightly then you should do a full wipe, especially if you're going from ROMs where there will be major changes.

Well you should have man, it is recommended to avoid most issues

Are you sure you unlocked the bootloader? The symptoms you describe are similar to a bootloop with the wrong kernel

Look at the root. 266 thread for unlocked bootloader..
It's exactly the same, the only difference is u have to flash the. 201 kernel again after finish rooting to experience improvements in the update..

Just a few questions please help. To keep our phone's warranty, we need to back up first the TA partition before unlocking right? I read and watched tutorials on how to back up but it needs a rooted phone so i search again on how to root, but unfortunately it requires unlock bootloader. Am i right guys? I'm using .201 all are stock and locked bl. Help guyrg.

"C6903_14.1.G.1.534_NUT.ftf" I hope? You can't downgrade using a flashable zip, you have to do it using an .ftf file.

Now you have to backup your TA partition, after that you can safely unlock your bootloader.

Then its gone forever.
There is no need to unlock anyway if all you want is recovery.
But now you have unlocked you may as well just flash XZDR kernel and then flash SuperSU then the rom of your choice.

Relocking Bootloader Xperia V

Hi all, sorry if this has been posted somewhere else on XDA. I used Fastboot with the code that sony sent me a while back to unlock my Bootloader. What I want to do now is to lock my Bootloader again to update to the new official rom. I would however love to flash a custom rom, but can't find a detailed enough step by step guide as to how. Also flashing custom kernals sounds risky, not sure if it is though, being the reason why I have not flashed anything beyond the Botloader. Help would be greatly appreciated.

You can use official 4.3 without relocking your bootloader.
