temp root for drm keys backup - anybody still interested?
- Thread starter j4nn
- Start date
That is incorrect information (or typing error).
No chance for XZ2 any model in my opinion. Checked XZ2 Compact - not possible.
And btw, it is mentioned in the exploit's first post.
@SilverGamer_YT, if you backup TA before unlock and restore it after, you can have nearly everything working as stock with unlocked bootloader (i.e. rootable).
No way to restore drm if not backed up for your phone if you are asking about that.

Something is still not sitting right in my head...
If we can not relock bootloader, then the warranty is still voided, so whats the point of going through all this process if we can simply install a fix patch?
by the way I gotta say and admit that you did a hella good job on this! all XZP owners applaud you for this genius work, we really appreciate the time and effort put into this, much love

If the tool works properly, when you restore your ta.img your bootloader will be locked and everything will be stock.
well as stated in previous posts, the restoration of the TA.img file wont relock the bootloader and some even stated that relocking the bootloader of XZP is not an option...
AFAIK none of the DRM fixes currently restore L1 Widevine.
Unfortunately, I long ago unlocked my bootloader and used the first DRM fix, will there be any way to get "true" drm keys back through this method or am I screwed?
As I have just tasted on my phone by restoring unlocked TA partition I found out that unlocking bootloader doesn't remove any DRM information. Your L1 is still there. Please check with DRM info app and post screenshot for confirmation.
Unlocking bootloader will only disable the sony proprietary things like camera, x-reality and x loud etc stuff.
@greatpatel007, in my opinion, you are getting false hopes.
When you unlock bootloader, device master key is erased from TA. And full factory reset is done.
This factory reset removes in my opinion also the access to WIDEVINE key.
What you have found/tested is interesting actually. But to simulate an unlock, you would need to do a factory reset too. Just try that and see if you still have access to WIDEVINE required media.
I believe it works like that when there is a proper device master key in TA, the phone is able to re-create the keys specific to each phone by use of the device master key to access all the other stuff in trust zone.
Your removal of dev master key removed camera functionality but for widevine it is probably needed only when the derived keys need to be created.
But this is only my opinion, I do not know the internals.
Just test the factory reset and let us know please.
TA backup before unlock and restore after allows to keep the device master key and therefore enables access also to WIDEVINE.
That is a major difference to any drm fix - those cannot provide WIDEVINE access.
Another major difference is that camera and widevine works on current stock firmware without any patching.
With those drm-fixes you may need always a new version which needs to be compatible with new firmwares.
First of all thanks for your hard work and time.
Today I'll received a XZP (8141), which is still around 9month in use.
I must read a little bit more to go sure, that all things are going well, before unlook the BL... There is only one chance, that I've recognize in this thread

Okay so it's just to clarify,
Right now I have gone through your temp root exploit process and backed up TA-locked.img but before I unlock bootloader I wanna know if I restore TA-locked will it change to stock like the good old days. Like how I received it.
Just wanna clarify before I unlock.

currently, as i understand, your phone gets the functions back from sony (such as camera, drm for pages/apps etc..) but your BL would be still unlocked as current it cannot be relocked. but since 9.0 the camera is working again, you should get the drm features back. but no video enhancement.
Ahaa thanks for the clarification, I think that's what I understood as well. I wonder if there is a way to restore the TA we back up as well. Anyways I did the backing up but didn't unlock the phone. Hope there will be a way to restore the TA.
Thanks bro
you can restore the TA partition but you cant relock your bootloader.
Can someone tell me where i can find service mode menu? new to sony and qcom.
EDIT: nvm, found it myself, i'm too lazy sometimes to use google.

Could I backup TAs on the new 47.2.A.2.33 Android 9 update before I unlock the bootloader instead of on oreo?
kountry83, if you like to use renoroot to backup TA, you need to run one of the listed FWs (and phones).
If I backed up my drm on 47.1.A.3.254_RU can I restore the TA image on M-ROM Pie v1. 1?
