Is it possible to restore DRM keys after unlocking BL? I have taken the backup of TA partition. Now after unlocking the BL can I restore the partition? Or it will brick the phone if BL is in unlocked state?
I did it this way first i flashed the stock firmware with flashtool in my case Xperia_SP_C5303_12.0.A.1.257_CE.ftf.
Than i rooted the phone with Doomlords Easy Rooing Kit v16.
I got no soft brick after i restored the TA, done before unlocking with BackupTA 9.0b5 and sure i did a dry run before i performed it.

No, no, mate, you missed the point. I want to know if restoring TA is safe with an unlocked BL.
EDIT: sadly, I know now that restoring the TA would actually relock the BL as well, and if there's a custom kernel installed it might result in soft brick. so I conclude there's no way to have DRM keys with unlocked BL. :crying:

Oh sorry, yes i also think this is not possible at the moment.
So you have to decide DRM or unlocked (custom Kernels).

I have .290 on unlocked bootloader with stock kernel and root. Since relocking is only a step away should i do it or will i brick my device or will i have locked bootloader without root.

I tried to restore TA partition (which locks bootloader) and this soft-bricked my device. I solved it flashing stock ftf with flashtool. I have the same question, I want to have root in locked bootloader, in order to have drm, keys and dont loose x-reality, and most important bionz processor.

I backed up TA in 534 and restored in 290, I didn't know it could make problems. Anyway, how could I backup TA in 290? There is no real root for this firmware.

Hi everyone!
After searching for rooting newest firmware of 12.1.A.0.266 with LB, I found that it may be impossible without unlocking my BL. So I decided to unlock BL & root it via DooMLord's method and relock again. But I have a few questions.
I heard it's important to backup my TA partition before unlocking so I do a search for it. So I found that root permission is needed for backup TA. Since firmware 12.1.A.0.266 cannot be rooted, I have to downgrade to Android 4.1 and root it by DooMLord's method. It's all OK for me.
But I need to know, if I do restore my TA backup that taken while running Android 4.1, on my newest firmware 12.1.A.0.266, can it be conflicted that lasting bootloop or bricking my device? And relocking my device will it definitely lock my BL to factory status? Please be kind to help me with these questions. :good:
Thank you all :laugh:

No restoring TA wont cause bootloop but to be extra sure you can first flash 4.1.2 restore TA and flash 4.3..

My friend,
Thanks for helping me! :good:
If I restore TA mean I'm relocking my BL. So if I flashed 4.3 again I cannot gain root access coz it cannot root without unlocked BL. Am I correct?
So how can I root 4.3, if I flash 4.3 over 4.1.2 as root is lost after flashing a new firmware.
Thank & Regards! :good:
You need to root on 4.1.2, install CWM. Download and flash a 4.3 ROM and last flash 2.266 kernel
But there are proper threads for this xD

Yes brother..... I see several threads that explaining how to do that. But I wanted to root official firmware by unlocking BL.
If I restore TA, should I relock BL after that or, first relock BL then restore TA?
Thanks!

To make it easy, unlock using flashtool. It'll automatically make a TA backup. Later when you're done flashing stock kernel you can easily click relock and it'll restore TA and relock it for you as easy as 123.

Bro,
Is that unlocking BL via Flashtool exactly same as unlocking via official Sony method? If I unlocked BL besides official method, can I relock it again successfully? And so, since official method needs to device connected with Fastboot mode, but Flachtool needs device connected via Flashmode to Unlock/Relock BL. Why is the different with this methods? Pls kindly explain this......
Thanks! :good:

Yess absolutely the same. I'm not sure about relocking it after using the official method but I think restoring the TA key actually means relocking it. Well actually you will need to fastboot on flashtool right after the flashmode. There is no difference in result. It's just an alternative way to unlock and relock. Unlocking using official Sony method is the old way of unlocking. Flashtool is just to make it easier and simpler. The result will be the same. But be sure that you make the TA backup before unlocking it for the worst case scenario not to be able to relock it

Android 4.3 Stock .266
ROOTED Locked bootloader
Hi guys,
I'm kinda desperate right now. I am using 4.3 with 12.1.A.0.266 firmware.
My aim is to install CWM. For this I need an unlocked Bootloader and Root.
But all tutorials I could find are kinda contradicting themselves.
To root I need UB.
To unlock Bootloader in need to Backup TA partition.
And to backup TA partition I need root.
The tools from doomlord all require the old firmware, but silly me has already updated.
Is there any way to unlock Bootloader without root for backuping TA partition OR root with locked bootloader?
Any help is appreciated
Im afraid there isnt any root method for locked bootloader, so You must flash 4.1 using flashtool, root 4.1, backup TA, flash 4.3, unlock BL, root 4.3 and relock BL by restoring TA. The whole process just sounds hard and its complicated but follow those steps and itll be fine
Cheers

When updating to 4.3 I lose root, dont I? So there must be a way to unlock BL with no root? I think then i would lose my Drm keys, thats why i backuped them on 4.1, didn't I? And i surely can use the backup of TA i made in 4.1 for version 4.3?
Thank you for your help already!
Same, Bro

i am afraid you cant get ur DRM keys back as you didn't took a TA backup before unlocking bootloader.. :
If i make a TA Backup, will i be good to go with rooting and all that stuff without having to worry about anything?
With a backup, will i always be able to downgrade/upgrade to any custom firmware/original firmware, and or use kernels and stuff.
Unlock/Lock Bootloader.
Can i always go back to stock phone with drm keys and lock bootloader making it 100% factory stock?
And can i have a rooted device with unlocked bootloader + the drm functions working?

The answer of all of your concerns is yes and yes you can always go to 100% factory state with your ta backed up ......
Assuming you will not mess up in flashing roms............
Are you sure? Cause what ive heard is, that you may backup your TA, but the DRM-Keys will remain forever lost.
For further information, this Thread questions the consequences of loosing DRM-Keys

Does not making a backup of TA = Backup DRM Keys.
And how can you screw up flashing roms?
Yes.
"And can i have a rooted device with unlocked bootloader + the drm functions working?"
Not sure about that, what I know if you Unlock Bootlader the DRM Keys are lost and they do not working. Anyway if you have Backup TA you can go back to Stock with functionally DRM Keys.
Downgrade to 4.2.2, root via vroot and use ta backup and you good to go. Did the same.

So I got something confused there. Good to know that I can always revert to pure stock.

Wrong. If you backed up your TA partition before you FIRST unlocked your bootloader, then your DRM keys are fine within the TA backup.
Test this if you like by downgrading to 4.2.2 WITHOUT restoring TA. Your camera will not focus etc etc
Now restore TA and as if by magic, everything is fine again (though your bootloader will be relocked)
Hi there everyone, i would like to get my phone to the brand new state. Currently it has unlocked bootloader, latest stock firmware and it is rooted. I also have a backup image of TA partition(BL Locked). Do i need to do anything else than flashing stock firmware and TA partition to preseve all the fuctionality (especially fully working camera)? Will it be possible to unlock the bootloader once again in the future after performing this?

Restoring the TA restores DRM functions, it doesn't relock the BL, which you can't, hence why there are no threads relating to locking the BL of the XZ1 Compact.
