<SOLVED>[Q] TA backup with firmware 14.3.A.0.683 (Sony Xperia Z1 C6903)

Hi,
I'm trying to backup the TA on my Xperia Z1 (C6903) running the stock KitKat firmware (14.3.A.0.681). From what I understand though, you need root to backup the partition, but to get root, you need an unlocked boot loader. I've seen a few tools that roots without unlocking the boot loader, but I need to downgrade the firmware to at least Android 4.2.2. Downgrading requires an unlocked boot loader.
Are developers working on a root-and-unlock tool for 14.3.A.0.681? Is there already a tool out there?
Thanks in advanced. Sorry for my arrogance.

You do not need an unlocked bootloader to get root and or to downgrade. Although yes, you would have to downgrade to 4.2 to get root. Just use flashtool to downgrade and pick a software to root

Cool
Just a couple more questions. Any suggested 4.2.2 and 4.4.2 firmwares to flash (if you can, link them here)? To root 4.2.2, do I simply click on the unlock icon shown in link?

I've used vroot 1.7.3 english and everything installed fine. However, when I installed the Root Checker app from Google play it reads "Sorry, this device isn't properly rooted."
Here's what I did / planning, in order:
1) Downloaded C6903 14.3.A.0.681 Global 1277-2880_R5C
2) Downloaded 14.1.G.1.534 downgrade FTF [NUT]
3)Pasted the 2 FTFs in the Firmware Folder under Flashtool
4)Flashed 14.1.G.1.534 downgrade FTF [NUT] using Flashtool from Androxyde (latest version)
5)Installed vroot English (1.7.3)
6)Clicked on the Root button. Phones reboots twice
7)After phone first start I was greeted with an error message from "Kingsapp".
8)Installed Root Checker from Google Play
9a)"Not properly rooted" <-- I'm right here
9b)If "root successful", proceed to flash C6903 14.3.A.0.681 Global 1277-2880_R5C
I did some research and people are pointing everywhere, vroot, bin4ry's rooting method, 360 (can't install).
Did I lose my TA partition? My X-Reality goodies?
What am I doing wrong?

Okay so now you are still on .534 firmware right? Do you have usb debugging on?
And also try rooting with bin4ry if vroot doesn't work for you.
Don't worry, you won't lose x-reality unless you've unlocked your bootloader

"Su upgrade failed. Missing root permission"
Yes, I'm on the .534 firmware. USB Debug turned on.
I'll try bin4ry's root now.
Once I'm through TA backup, I just need to flash 14.3.A.0.681 Global 1277-2880_R5C?

If you still can't get root, try using nuts z1-lockdualrecovery installer and after flash nuts .681

Thank you very much for fast response.
But, a method like "kingroot" on marshmallow don't work? I mean, a root method that don't cause lost of DRM, functionality and so on?

It is not possible to root your device without unlocking bootloader for now.. Afaik you have to backup your TA by downgrading FW to LP, Then update to MM, Unlock bootloader, Flash Rootable Kernel, Flash Super SU, Flash DRMrestore..

Do I need to unlock bootloader first? I have stock firmware 32.2.A.0.305. I don't want to back up my DRM, just want to have root access.

Well, I think it is not possible to root without unlocking the bootloader. It is recommended to backup ta partition. Unless you backup the ta partition you will not be able to use x reality engine,software updates etc..
I don't know whether a prerooted firmware can be used to root without unlocking the bootloader.

can i install TWRP with this kernel??

1. No exploit has been found, you indeed need to unlock BL to gain root access. You will lose usage of x reality engine etc once unlocked.
2. But, you are able to use x reality engine etc. as long as the DRM fix is in place in new kernel.
3. You cannot use anything else than official firmware as long as the bootloader is locked.

Now you don't have to install twrp manually. I have merged recovery with the kernel.
Download the same from attachements.

Not sure the backup TA tool works or not in MM, if not working you'll need down to LP first.
Okay, if you can backup your TA in 305, then yes, lock bl via Sony offical unlock site and flash the elf kernel in this thread with flashtool. Remember to flash the supersu in twrp too.

I think it is not possible to backup TA on 305 because the ta backup tool only supports LP kernel.
You don't have to flash supersu because the kernel contains the latest supersu build.

If you don't care void warranty or come with no warranty, you can just unlock the BL now.
http://www.xperiablog.net/2015/03/17/guide-to-installing-xperia-lollipop-using-xperifirm-and-flashtool/
If you need to keep the warranty, you'll need to run XperiFirm to download any 152/200 firmware and follow this guide to create the image to flash.

Did anyone experience any bug in the kernel?

installing your kernel now probably need a day or two to tell any problem from your kernel or 305

Early testing showed no problem. DRM patched and twrp working fine but default set at enforcing mode, can you set the kernel to permissive mode?
OMG, opencamera can't recording 4K video(actually FHD seems not work too) on 305 while no problem on 224/253. I've to roll back and stick with XPower V3 now.

It would be so nice if you could give us the complete rom to be flashed via twrp I don't have a pc

You can just flash the SuperSU+Aroma+2.78-SR1+v3.zip in twrp, it got options to pick system mode or system-less mode.

I ain't that good at this stuff, but I was brave enough to flash a DRM-fix for Z5. It actually booted and made me able to root it, so I'm happy! It ain't my work, but I couldn't find the original post, so I hope it's okay to upload the .zip I downloaded!
Edit: Phone reacted pretty slow and camera didn't work, so trying some other things!

Downloaded the firmware and tried fix the kernel. Rootkernel v5.0 stuck at drm fix.

I have seen that you are one of the first Rooter of this phone and followed your posts.:good:
I'm Rooted running Stock firmware with custom recovery. Can I follow this guide for re-locking bootloader?
So theoritically,
1. flash a lollipop ROM using Flashtool
2. Restore TA Partition (this will relock the bootloader?)
3. Flash Marshmallow ROM and then wait for Android N update?
Do you suggest to wait for DRM fix and use Rooted Nougat?
Thanks.

Newbie question on Rooting X Performance

My X performance is now running Nougat. I am going to downgrade it back to 6.0.1. And therefore I downloaded the FlashTool. I can install the Flashmode Drivers and Fastboot Drivers. But I can't find the Xperia X Performance drivers in flashtool-0.9.23.1-windows. Do I need to manually download the drivers from https://developer.sonymobile.com/downloads/drivers/xperia-x-performance-driver/ and right click on .inf to install the drivers in Windows?
Secondly, since I never unlock my bootloader, I am going to backup using the backupTA_v2 via the Dirtycow. However, I wonder if I restore the TA partition after I root my phone, would the root also go away? Basically, I want to have my Xperia X performance in root state while having the original TA partition in place so that I can run the PS4 remote play app. As far as I understand, all the DRM recovery patch out there don't fix the PS4 remote play app.
Thanks.

So for backing up the ta does it matter that I will flash UK variant marshmallow on my Australian firmware phone? Sorry I know it sounds like a noob question.

We backup TA partition because we want to keep SONY's special functions AFTER unlocking bootloader.
If you just want to flash different variant firmware, you don't need to unlock the bootloader, just find the FTF file and flash it into your phone.

Ah but I'd like to downgrade to marshmallow(of available UK variant) and then unlock bootloader, root and then XPosed. So is TA even relevant for me?

Yes. Since you want to unlock bootloader, backing up TA partition is relevant to you. But you can only backup TA partition on Marshmallow (because SONY fix the dirtycow on Nougat). So you should downgrade first, then backup TA partition, then unlock bootloader.
