Also not working on Xperia X Dual F5122
it will show that it restored your DRM Keys successfully, but it will brick your device.
had to use flashtool to flash firmware again to unbrick it.
EDIT:
Okay so this did restored my DRM Keys, I am seeing that my bootloader is locked again and I have my keys restored again, so I guess to restore on F5122 you have to brick your device once to get your keys restored. strange!

Thanks DevShaft for a great tool to backup the TA.
Sent from my Sony Xperia M2 using XDA Labs

I had to re-do the restore after TWRP update (where I have un-locked/re-locked BL) and it did not work initially as was also reported below.
Solution:
Check if your internal sdcard path matches the script content and change if needed in backup.bat and restore.bat. I think I had to adapt for LP backup (sdcard1) but original is ok for mm (sdcard).
Please make sure that you have no other adb process started on your PC trying to access the device (flashtool, TotalCommander ADB Plugin and others). Terminate all of them (use windows process manager to make sure) and only then start the backup-Tool. Any weird problems (TA partition not found, image got corrupt while pushing to sdcard) may appear if you have no clean single access of the backup tool to your device.

You could restore your TA partition's backup, in img format (upacked from the zip file generated by this tool when you backed it up) by a dd command, like this:
dd if=[path_to_TA.img]/TA.img of=/dev/block/platform/msm_sdcc.1/by-name/TA
Where the path to your TA.img file has no square brackets.
Make sure the TA.img is from the very same phone you made the backup. Otherwise you'd turn it into a permanent paperweight.

hI GOOD DAY can i get some assistance please...my ta backup is in .img format also right but question how do i flash it with your instructions..
1. Do i have to be rooted ?
2. Does my device bootloader have to be unlocked or can it be locked?

As I root all devices I get, I don't have problems. This restore operation by a dd command to the TA partition actually relocks the bootloader, if it happens to be unlocked, but why would anyone wish to restore his/her TA backup it his/her bootloader had never been unlocked? Anyway, I guess that root access would be a must!
ok i just rooted and unlocked my bootloader and installed twrp..
i dont know the dd command u speak of can u walk me through how to do it plz..i have the ta.img saved on my destop

It's a Linux command. You could launch either on your phone, through any Terminal emulator you could download from the Play Store, or from a terminal command window on your PC. You could download this amazing Minimal adb and fastboot tool https://forum.xda-developers.com/showthread.php?t=2317790, unpack it anywhere in your PC, go to that directory and enter:
adb shell (skip this command if you are typing it on your phone)
su
Now, supposing your TA img is on the root of your internal storage, the dd command would be (it's case sensitive):
dd if=/storage/emulated/0/TA.img of=/dev/block/platform/msm_sdcc.1/ by-name/TA
Good luck!

Enter command su, prior to entering the dd one, and remove the space before by-name.

No, su is to acquire superuser privileges, and dd is the actual copy command.

Backup TA for Sony Xperia
Backup TA can backup and restore the TA partition of the device. When you create a backup before unlocking for the first time, then you will be able to restore to full factory state (including a locked bootloader). This means all DRM keys intact, Bravia Engine working in Album and last but not least your warranty when needed :highfive:.
NOTE: When you did create a backup of your device's TA with another tool or Backup TA v4 or earlier, you are able to convert it to a valid Backup TA package by choosing 'Convert TA.img' from the menu. When you've done this you are able to restore it safely.
READ FIRST: At the bottom of this post is the FAQ. Here you will find answers on the most asked questions. Read them before posting any question in this thread. When you want my support, tell me which device and version of Backup TA you're using and attach the complete output. I can not help you without this and besides it's really not so much to ask in return, now is it? No effort without effort.
This tool currently only works under Windows. Mac, Linux, and native Android will be supported in the future. Using this tool is at your own risk.

Backup Video Tutorial. Kindly provided by @shem2409:
FAQ
Q: Is my device supported?
A: Look at the supported devices list above this FAQ. When it is not listed, try to make a backup it will tell you if your device is supported.
Q: Do I need root for this?
A: Yes, you do need root for both backup and restore to work. I would advice to use @DooMLoRD's excellent Easy Rooting Toolkit for this, when not already rooted.
Q: Can I use someone else's backup?
A: No, this will hard-brick your device.
Q: Can I restore my TA.img file from Backup TA v4 and earlier or another tool?
A: Yes, choose "Convert TA.img" in the menu.
Q: Does it bring back my DRM keys when I already unlocked my device before making a backup?
A: Not without a backup of the TA before it was ever unlocked.
Q: Can I restore my TA while running a ROM with a non-stock kernel?
A: Yes, but it will soft-brick your device and you need Sony PC Companion or Flashtool to fix it by flashing stock firmware. Best is to first return to a complete stock ROM or at least flash a stock kernel (do not confuse with stock based kernel!) before restoring the TA, this prevents the soft-brick.
Q: Will a restore relock the bootloader?
A: Yes, it will relock the bootloader like it was never unlocked.
Q: What is 'restore dry-run'?
A: When you do a dry-run restore it will perform a regular restore with the exception that it will not write anything to your device. This is helpful to test a backup without actually restoring it.
Q: What is the correct file size for a backup?
A: The TA partition size can differ per model, so there is no one answer to this question. You can rest assured that your backup is fine, also in file size, when the tool says the backup was successful.
Q: Why do multiple backups often differ in size?
A: The TA partition also contains a logging area which changes every time the device boots, which then leads to different compression size per backup file. Nothing to worry about.59I write this post to inform you that I will not maintain this tool anymore. There are a couple of reasons for this.
Nexus owner
Since I bought myself the Nexus 5 I have vowed to never buy a non-nexus device (when Nexus is available that is) anymore. Reason for this is the latest updates of Android, the bootloader which can be unlocked and relocked without having to find locked root first and then make a backup of keys or certificates to still have warranty without questions asked. So another Sony device (or any HTC, Samsung, LG, Motorola, etc for that matter) will be highly unlikely for me.
Window 8+
I got this beautiful Apple Macbook Pro from my work and I almost never touch my Windows machine anymore. On this machine (old one) I can not install Windows 8 or later since it is not compatible. Therefor I am unable to give support to the latest Windows versions.
No time
I have found some other interesting hobbies I would like to spent my time on. One of them is AI and the other is sports. With that, and my personal life in general, there is no time left to work on projects as these.
Since this project is licensed under MIT, anyone can pick up the maintenance or start their own tool. This thread and their downloads will not be removed, so you can always download the tool for a restore or backup.29ok another update....somehow i managed to go past usb debugging screen. removed the sony pc companion....installed sony z ultra ADB drivers, reconnected the device and started backup TA. it took a successful backup. then I tried to test the back using the option restore -dry run. but after running that function i came up with this error. now what is this? should i ignore this error?
I have tried this on windows 10 64bit, I am pretty sure it'll work on 32 bit too.
Download the zipped find.exe in the attachment.
Replace it with "find.exe" in the following directory
Code:Backup-TA-9.11\tools16Backup-TA for Sony Xperia Z / ZL
Great that you made a new one, may keep others from uneccesary bricking their devices :thumbup:
A thing for the FAQ would be the softbrick when restoring on other than stock and and that it only works on totally stock, not bringing DRM keys to other ROMs when unlocked.
