I have a xperia z1 (C6903) and i would like to flash the stock kitkat firmware from Sony into my device since there are a few bugs when i installed xposed framework. And i haven't unlocked my bootloader. So will there be any problem if i flash the stock firmware? Will my TA keys be affected by this?

it's always a good idea to keep a backup of the ta partition table...
there should not be a problem. you will lose your data when you use the flashtool to do that...

That is incorrect
You will not lose TA partition by flashing a stock FTF. You can keep all your data if you tick to exclude data on flashtool.
However, if your problems are stemming from using Xposed the best bet is to just uninstall it. There is no need to reflash a rom.

So I installed CM10.2 on my phone. For that I had to root and unlock my bootloader. I didn't really like it to be honest so I decided that I wanted to go back to stock rom, the problem however, is that i'm not sure how I should do this. I made a backup of my TA Partition so I also could get my DRM keys (Bravia Engine, etc) back. I don't know what I should do first and I was wondering if there is someone who could help me through this process. Do I first need to flash stock kernel, then flash stock ftf, and then install that TA backup in order to relock my bootloader? But I thought I needed root for this, if I flash a stock ftf then root will be gone right? So many questions
Thank you in advance

Thank you for your response but this is only relocking etc. My problem is that I don't know in what order I should do things. So far I think I should do it like this (but i'm not sure, so i'm asking for someone to tell me if it's wrong) : 1. Simply flash a stock ftf (with the ftf the stock kernel will be installed too, right?) 2. Relock bootloader 3. Then apply the TA Backup to get the DRM Keys back.
Is this the right order to do things? Will I make an expensive brick out of it if I do it like that?
Flash a stock FTF and root it (or flash a pre-rooted stock based ROM through recovery ). Then restore TA, which will automatcally lock bootloader and restore DRM keys

Thank you very much, I tried this and it worked.
Hi, i recently down grade my C6903 to 534 and successfully root (thx to XDA), when i try to update the 257 and it's gone. they change to 290 now and i dont want it since it will lose the right of root. Is there any method update to 257 beside flashtool?
if i use flashtool update to 257, will i still have my apps and personal stuff after update? because when i down grade to 534, flashtool wipe out everything in my phone even i make sure i didnt mark wipe out my stuff (and i didnt update at that moment):crying:. so i dont want to re-install my stuff again.
if i use flashtool update to 257, will the right of root still exist?
Please advice me how to get 257 update with most less effort (as long as i can keep my apps and personal stuff).
Anyone can help?

Flashing won't delete your data. Make sure you've unticked data and app wipe in Flashtool before flashing. Always make a backup in case though!!

That won't work in his case, he already flashed and rooted 534 but he is getting OTA to 290 and not 257.
Only thing you can try is to flash 290 through OTA.
If you flash 257 without wiping data via Flashtool you'll preserve your data but lose root.
290 OTA probably won't keep your root but that's the only thing you can try...or to flash ROM from XDA

If your phone's bootloader is unlock-able, then you can back TA partition, unlock bootloader, install recovery, flash Supersu.zip, flash kernel from FTF (Don't wipe anything, exclude everything but kernel), then restore TA partition from your backup.
This way you will have a fully rooted Xperia Z1 Android 4.2 14.1.G.2.257

Hi I want to totally reinstall all the software and take the custom rom of my xperia z1. It has an unlocked boot loader.
Can I do this through PC companion?
If not, how would I do it? thanks

The easiest way is to use Flashtool. Just download an FTF of newest firmware and flash it using the software:
Once you are on a stock rom with stock kernel you can restore TA backup (if you have one), this will also relock your bootloader. It is best to restore TA on the same firmware that you did the backup.
Hello
I have Indian SP C5302. I want to install install the Australian generic 4.3 stock FTF (.266). I just read somewhere that one have to exclude TA partition while flashing it with flashtool whereas I have previously installed 4.1.2 stock FTF available here without excluding TA.
Can anyone please clarify under what circumstances one has to exclude TA or does not have to exclude TA during flashing stock FW.
Thanks in advance.

Just use search option. This question was in many threads after releasing 4.3 Or just read what exactly TA Partition is!!

Even if you select it on flashtool nothing will happen, it wouldn't get flashed, so choose either of them it wont harm your device.

Ok Got it!! :good:
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
