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

Do you have locked bootloader? If so, then you can't install recovery as you have partial root due to Sony's RIC in the kernel.

You can't "Fix" X-reality, but you can backup TA partition before unlocking the bootloader and whenever you want X-reality you can restore TA partition and get your bootloader locked again.

Because you should flash stock kernel before restoring ftf.
Try to flash stock kernel now, if it didnt work then flash whole ftf without excluding anything.
That happened to me, and that solved it.

[Q] How to go back to Stock official ROM sony xperia z1

I'm on ihackers 2.1 ROM android 4.3
rooted
unlocked bootloader
I wanted to go back to stock to C6902_14.2.A.0.290
I found the method but I'm not sure if this is the right way http://lionking853.blogspot.co.uk/2013/11/how-to-go-back-to-stock-firmware-on.html
and if it is the right way, after going back to stock ROM, will my phone unroot and relock again?
Can I just go ahead and do this or must I relock bootloader first?
please help me since I never done this before, only rooted and unlock that I did.
Thank you so much folks

I'm no longer rooted anymore but bootloader is still unlocked.

If you have an unlocked bootloader, you will not be able to update using PC Companion. I didnt know all this **** were involved in Sony phones.
I had unlocked my bootloader a couple of days back, didnt know I had to backup my DRM keys and ended up losing my warranty. Now I cant even update my phone using the official updating method.
BTW... the recovery is bundled with the kernel, thats why people refer to it as flashing a kernel instead of recovery. I didnt know this until 2 days back.

Thanks

If you do have a TA backup then you don't have to do anything else then restoring it on a stock rooted firmware..If you don't then use flashtool to relock it..
Revert back for more help..

If I am on a Locked Bootloader and on a rooted custom ROM, will Sony PC Companion detect my phone when the next update comes??

This is stupid. If you are in 4.3 (.290) with un-locked boot loader you cant update via PC companion or SUS.
I ended up going to 534 (4.2) via flashtool. Root it, restore TA backup and then use SUS to update. And flashing the latest 4.3 via Flashtool din work.

No PC Companion or SUS won't detect your phone.. You've to manually flash a valid ftf from Flashtool.. Then you can connect & update your phone through PC Companion or SUS..

[Q] Relocking Bootloader, kernel, updating and more!

So, I'm on Central Europe 1 4.4.2, with doomlord kernel and root. I have a backup of my TA partition before unlocking bootloader.
I want to update to Central Europe 1 4.4.4, using the flashable zip that was posted and the stripped ftf.
Should I flash the stock kernel from FTF 4.4.2, restore my TA partition backup and update? Or update to 4.4.4, and after that restore my TA?
What are the bricking risks? Should I wipe everything? :crying: SO MANY DOUBTS

Why relock?
Just update by flashing the file

If you want to go to totally "out of the box" device and have OTA update info and few other things you just said then yeah...
First flash ftf and stick kernel and then relock bootloader...
If you restore TA and leave custom kernel you could have serious problems...

No, there is no serious problem at all, you just need to flash a stock kernel via flashtool (In a stripped FTF or a full FTF) or via fastboot if you have the kernel.elf

So everything went smooth! Now i'm on 4.4.4 with root and locked bootloader BUT x-reality is not working LMAO. I'll try to install it now.
Edit: yep, it's definitely not working. I relocked bootloader for nothing! haha

Exactly what I said..
You have to flash stock kernel - there are many guys who relock bootloader on custom kernel - xda us full of stories like that..
They have toy now instead of expensive device..
Sent from my D6503 using Tapatalk

No, it's very easy to fix, just flash a stock kernel after relocking the bootloader, it does not brick the phone relocking in a custom kernel, it just gives you a boot loop which is easily fixable
