In this way I will not Flash kernel use custom ROM...
summary I want unlock bootloder use AOKP or CM ,and restore TA le't me use Z camera in custom rom
You can relock without restoring TA, but not vice versa.
If you restore TA backup, you always relock your bootloader. There's no other way unfortunately.
Bootloader locked = only stock kernel (or you will get soft-brick) = only stock firmware (or roms based on stock)
This is how it works.
About z1 camera I can't help you, but remember that if you want to run AOKP you have to be unlocked ALWAYS.

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.

Hi All
I Was about To root my ZR But I saw TA Backup and i was wondering what is it ?
What Is It For ?
what can i do with it ?
and is there is any other things should i back up or do before root and play with my ZR phone
I Know TA backup need root .
but will root unlock bootloader and is yes does all methods unlock it
and what is bootloader and what means by unlock it ?
sorry for all these Q But I'm New To Sony
Some linux basics (android is linux based)
What is a kernel:
http://en.wikipedia.org/wiki/Kernel_(operating_system)
In short: a kernel is the link between hardware (CPU, RAM, sensors,...) and software (ROMS)
A kernel and a rom must be compatible. A Sony rom won't work with a cyanogenmod kernel.
To answer your questions.
Unlocking bootloader is requiered when you want to use a custom ROM, because that ROM uses another kernel than the ones from Sony.
So it is kernel related
Rooting means to have superuser access to system files of the ROM. It is software related
When you will root your phone, your bootloader will still be locked.
It is reversible: you can also unroot a ROM.
The TA backup is a tool that make a backup of your TA partition. This contains your DRM keys.
When you unlock your bootloader, you will lose your DRM keys. Protected library's from Sony( like Bravia engine,...) will not work any more.
You can restore your DRM keys on a sony stock ROM with the TA Backup if you don't want to use a custom rom anymore (sell phone, warranty issues,...)
Thanks alot
And another Q
If i'v problems with imei and baseband (like null)
Will TA backup solve it or what?
Hello!
I currently backed up my TA Partition and DRM Keys using Backup_TA.bat, I now have an Unlocked Bootloader and also am running on a custom kernel ( FW .232 Lollipop ), my question is if I use the restore function on the Backup_TA.bat will that re-lock my bootloader?
Thanks alot!

Yes it will relock BUT
You need to be on an official firmware and rooted. And you must have the stock kernel. Then only you can restore. If your restore TA, it relocks bootloader. And custom kernels don't work on locked bootloader so you will end up in a bootloop if you are not using the stock kernel

Btw, do you another way of relocking the bootloader besides using Flashtool?
i try using restore in backup_TA but my bootloader its still unlocked
im on stock rom and kernel + root, in flashtool i dont have option to relock :/
Restoring TA is supposed to relock bootloader automatically aa far as I know :/
I was trying flash rom 4.2.2 and i checked "simlock.ta" option then my phone note sim card not valid and lose some funtion like camera but i can fix by install restore drm key funtion in here:
http://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672

Is your bootloader unlocked? Is your phone C6902? Why in the world would you want to flash antiquated 4.2.2, especially if your bootloader is unlocked. The unlocking guide specifically states you have to be at least on 4.3 in order not to lose camera. If your phone is C6902 and you flashed C6903, you have a wrong baseband.
No. You can't use another phone's TA backup, unless you want to brick your phone.

I am not familiar with SOL23, but if your bootloader is locked, there is no permanent damage. You just need to re-flash the original firmware for SOL23. Try to repair it with Sony flashtool...
You have to restore your phone to original, then, if you want to unlock bootloader, do a TA backup, so that you can restore DRM function in case you would want to relock. If you unlock without backing up, you will lose your DRM key forever...
Hello, after my patience ran out with google play services batter drain issues i have decided to try out moding and i think i messed up DRM recovery part.
I used https://forum.xda-developers.com/z3-compact/general/how-to-root-backup-drm-keys-t3013343 this as a guide.
Things i have done so far in order:
1. flashed 4.4
2. rooted
3. made DRM keys backup
4. unlocked bootloader
5. installed twrp recovery
6. installed this https://forum.xda-developers.com/z3-compact/development/rom-aoxp-rom-v1-t3478863 rom
7. recovered DRM TA zip thing.
Now my problem is, my bootloader is locked, so i guess recovery procedure went ok, but camera perfomance is as awful as without drm keys. Where did i go wrong? What can i do to fix my camera perfomance?
p.s. i am really sorry for my english as it is not my native langue thanks in advice for help.
You don't lock the bootloader when you restore the TA backup it actually locks the bootloader,so try unlocking it again and then restoring the TA backup

Sorry.
What I meant to say is,when you restore a TA backup from an unlocked bootloader state,it locks the bootloader when you restore it.
So what I am saying is you should unlock the bootloader again,and restore the TA backup as it will lock the bootloader again and should restore camera quality.
Clear now?

yes, but one thing. Why do i need to restore twice to get back camera quality?
Thank you a lot!

I dunno tbh I never restored a TA backup since I was an idiot and forgot to back up TA when I was going to unlock my bootloader.
Try it and tell me how it went! Good luck!
No need to restore it twice! Just be sure that you are on stock kernel before you restrore TA.img
Savest way is to flash Kernel+Bootdelivery out of normal FW tft using flashmode (not fastboot !)
Then restore TA.img with Backup tool.
Reboot and done... And Camera is back....
As an alternativre you can flash DRM fix as well... There is also an other projekt running to mount your TA.img from another location.
But this is not yet tested that much... Stay with locked BL and TA - Or with UB and DRM fix.
DRM fix
https://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672
Sometimes its needed to delete following folders (with all including files) to reset DRM stuff (root needed)
/data/credmgr
/data/drm
/data/mediadrm
Don't be afraid of loosing something - Those folders and files will be created automaticly new on boot....
btw: Why you unlocked your bootloader? For Root we have 2 ways to do it without Unlocking bootloader...
Anyway -if you have an TA backup you are save actually...

There are also two ways of using TWRP:
One is to flash twrp.img onto former FOTA partition. For this you would need UB... This works only with new bootloaders (LA3.0_M_3 from FW .291 is prefered - This bootloader will be installed if you flash full FW 291 or only bootdelivery and kernel in flashtool)
https://forum.xda-developers.com/z3-compact/general/d5803-z3c-aries-twrp3-0-t3543113
But the other method is putting TWRP files to /system/etc/mm_twrp_recovery on SYSTEM partition...
This works also with LB!

EDIT
Third one is to have recovery build into kernel...
Just to be complete.. ?
