UNMAINTAINED! See this post

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 .

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.

FAQ
Q: Do I need root for this?
A: Yes, you do need root for this to work.

Q: Does it really work?
A: Really?

Q: Can I use someone else's backup?
A: No, this will hard-brick your device.

Q: Does it bring back my DRM keys etc. when I already unlocked my device?
A: Not without a backup of the TA before the initial unlock.

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.

So, can we finally speak about that at this stage we all can unlock the bootloader, mess with the phone, install any room, do whatever, and in a couple of months, flash a stock rom, root, and then restore the TA backup having the phone intact, as if I never unlocked my bootloader. RIGHT?

==============================
Fixed Bugs
----------
- Fixed bug in IMEI input.
- Added choice.com as part of the tool instead of relying on Windows.

This means that I have to do a new backup?
.

No IMEI input is only for restoring. The bug was when you provided your IMEI before in the same session, you could just leave the input blank the next time you restore and the tool would just continue. It would use the previous input for check, which in most cases would be the same anyway, but is not how it should be.

if i had made backup of my TA for 3 times before i unlock my BL (just to make sure i got plenty of backups) and they all have the same md5 sum, can i be sure that they're not corrupt copies?

They surpassed the integrity check, didn't they?
You can perform a restore dry-run to see if it also passes there. When it does you can be pretty confident all is fine.

i made the backup using ur earlier v6 tool, not sure if they passed integrity check but the backup process was "successful" according to the tool so i guess it's safe to restore?

will try to restore on next full charge=] Thx for the great tool!!

Since you made the backups with v6 its better to first try "Restore dry-run" before the actual restore, just to test and see if all goes fine. The integrity checks in the older versions were not as good as they are now.
