I have an Xperia Z C6603 with unknown baseband but with correct IMEI code. I read the guide but I cannot understand how to resolve this problem. I would appreciate if someone could help out.
P.S. I successfully restored the DRM Key with backup TA. The phone works perfectly with the exception of signal reception. I tried to upload some firmware by selecting only baseband but I still have the problem.
Thank you for your help.

hi hope someone can help me..
i tried to restore my backupTA in my z3c but i get:
failed to copy 'tmpbak\TA.img' to 'sdcard/restoreTA.img': Permission denied
...i see now a 2mb file in my sdcard called revertTA.img
also tried after relocking bootloader, same error. do you know why?
EDIT: it seems I fixed the problem reflashing a stock kk fw with flashtool (.93, the same I used to backup TA), that probably fixed something in the sdcard, and then re-trying the restoring! :good:

You can use the serial to determine the device.
When you run "adb devices" it shows the serial number of any connected device. It also shows in the Settings → About Phone → Status screen.

I backed up my TA Partition of my ZR running Kitkat, then I unlocked the bootloader, flashed stock lollipop firmware. I want to know if it's okay to restore TA with Lollipop installed?
I have a backup of drm keys but when I want to restore them,ta backup can not find backups.How can I solve that ? I am on 4.4.4 .93 kitkat stock sony kernel bootloader also unlocked and rooted
Edit:System detected keys so no problem.When I made backup,I was in Lolipop but now I am in Kitkat so must I return to Lolipop for restoring ?

Yes you must be on the android version which you performed the TA backup. So in your case revert to Lollipop and then restore.
You will have to test and see. It worked for me; I saved TA partition on kitkat last year, and unlocked. Flashed a bunch of roms over the months while unlocked, and just restored my TA while on a lollipop stock rom today.
My bootloader reflects that it is locked, and the graininess is gone when taking lowlight photos. Because of this I am convinced that the relock went fine.
I'm on Z1C, and like I said you'll have to try for yourself ; it might now work for everyone.

Just be rooted (any firmware) , with usb debugging enabled, run the tool, and select your original backup to restore TA and get your DRM keys back. Make sure you are on a stock Sony kernel before rebooting though, or else you will be soft bricked.

Querry about Unlocking bootloader
I have taken TA Backup before unlocking the Bootloader and tried restoring it after unlocking it many times. It works perfectly everytime. My doubt is - Every time we unlock the bootloader, the phone gets factory reset. To avoid this, can I take a TA backup of unlocked bootloader? By this, I will have 2 copies of TA. one with locked Bootloader and other with Unlocked Bootloader. So, i can restore the TA backup (of unlocked bootloader) to unlock the bootloader without factory reseting it?

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.
