Hi
sorry for my bad english.
about a years ago I change my bootloader unlock allowed status with plasmatool.exe by using what mentioned in the link below:
http://forum.xda-developers.com/showthread.php?t=2151778
and when I unlocked my bootloader I saved a backup of simlock.ta file by using plasmatool.
now my bootloader is locked again and plamatool doesn't work but backup files still exist. is there any way to restore these files ?

Hi guys,
I am seeking help. I had an unlocked bootloader for a while and then relocked it via flashtool. Now I would like to unlock it again, but flashtool throws errors on me:
- Command not succeeded or Failed: Device is rooted already
I do not have root (checked with root checker), and the .ftf firmware I have flashed was .108 Generic Europe.
Any ideas what's going on?

How did you backup your TA Partition?
A few months ago, I had the very same issue. However I never used flashtool to relock my bootloader.
For me, I am in the belief that I had an issue with TA Backup 9.10, as after I restored my TA Partition via TA Backup 9.10 from a backup made from the same version I would be faced with the same error. As I had previous used TA Backup 9.9 to backup my TA Partition, I tried that version with the backup it had made, and I was able to unlock my bootloader again.
Summary
Using TA Backup version 9.10 to backup my TA Partition and then restore it to relock the bootloader resulted in Command not succeeded or Failed: Device is rooted already. When trying to re-unlock my bootloader.
Using TA Backup version 9.9 to backup my TA Partition and then restore it to relock the bootloader, Fastboot was able to unlock my bootloader again.
Thanks for a suggestion. However I managed to unlock it with a different method.
In the flashtool folder, check if
[FLASHTOOL FOLDER]/custom/mydevices/[DEVICE SERIAL]/ulcode.txt
exists.
If not, create the folders along the way there and then use notepad or something very lightweight to create the ulcode.txt. Put in the code, be sure to enter the code without the 0x, so just the code as it came from Sony. Save the file and start FlashTool.
Cheers.

Hi,
I had the S3 and switched to the Z2 last month. So I am new to the bootloader thing.
Is it right that I can relock the BL by restoring the TA partition for warranty for example?
Or can Sony see that I've unlocked it?
just be sure to backup your TA, and you can go back to your original undetectable state
.....
Hi thx for your reply
So when I restore the TA the BL becomes locked again? Or is it possible without locking it?
And do I need a new backup when I update from .402 to .314 ?

Why do you need unlock at all? Exist root methods without unlocking...
When I want to install a custom kernel for example.
Restoring the Trim Area locks the bootloader.

Does locking the BL wipes data the same as unlocking it?
Yeah m8, re-locking your bootloader will wipe your phone so, as always do a backup first:good:

I have test voodo unlock galaxy sim unlock and others solutions and i have too downgrade to 4.3 Help me please @Blekota @JustArchi
If it was unlocked previously then it doesn't relock, unless a file corrupted and it restored a .bak from before you unlocked.
There is no way to unlock for free anymore.
Help

I don't understand , please make a full tutorial how to restore .bak and i have an nandroid backup of my rom just after the unlock
E2303, 8GB. Phone image was downgraded temporarily to root with xperiarootkit & backup TA. Latest stock image (with carrier branding due to connectivity issues without it) was (re-)installed afterwards, bootloader unlocked, TWRP installed & phone re-rooted. TA was then restored. SIM card is perma-locked to carrier. ( )
Phone is rooted, TWRP works, bootloader status is still unlocked (???), TA partition exists, but DRM features like ClearAudio+ etc. are missing from the settings. Anyone have any idea what's going/how this can be fixed? Does Backup TA not restore correctly (or worse, backup incorrectly!!! This would be VERY bad!) on the M4 Aqua?
I unlocked without backing up drm Keys and i have normally working phone with Clear Audio+...
What next features dont working u?
Normally you have to re-lock your bootloader for those DRM-related features to work again. At least that's how it was on my Xperia SP.
Can anyone tell me all DRM features on this device please?

That's the thing tho: TA Backup didn't relock the bootloader.

if you did a TA backup when the Bootloader was locked and if you use the TA Backup tool to restore it, it will lock the bootloader again.
thats how it worked for me on my Xperia z and now Xperia M4 (E2363)
How did you backup and how did you restore? The restore perhaps didn't work because the TA partition has to be set to writable (via blockdev command).
This is just a guess. I didn't unlock yet but did a backup of TA (manually, not using some batch files because I don't trust them and I run Linux and Win batch files won't work).

My apologies for being a month late with this.
Flashtool provided the option to re-lock your bootloader. So, once you've restored your TA backup you can then use flashtool to re-lock.
Hope this was useful. :fingers-crossed:
Cheers,
Re-locking using flash tool only locks the bootloader but does not restore the DRM certificates.
after re-locking with flashtool you can use PCC to repair the phone and get OTA updates, but the DRM certificates are not restored, they are lost for good.
unless you have used TA Backup (http://forum.xda-developers.com/showthread.php?t=2292598) to backup the TA partition when the bootloader was locked and the certificates were all ok and valid, you need root with locked BL for this to work.
Restoring the TA partition with TA Backup tool, locks and restores the drm certs again root is required for TA restore.
i know because mine worked.
