Just bought a new Xiaomi mi 6T device. My previous phone was a Sony Xperia m6. To unlock the bootloader and get root access was a bit of a pain on the latter. I remember having to backup a ta-partition to secure my DRM-keys.
Wanting to unlock the bootloader on this device I couldn't find any information about backing up and restoring a certain partition to secure the DRM-keys. What I did find was this post on the mi community forum about how unlocking the bootloader results in the widevine beïng downgraded from L1 to L3 (read the post for further details. The only way to reverse that process is to relock the bootloader again according to the the information I found.
So this is my question: Is there a way to keep the widevine L1 version, with better HDR performances, with an unlocked bootloader by backing up and restoring any data or partition on the phone that is responsible for widevine or other DRM content?

No, you don't loose L1. You don't need to backup anything. You will allways have L1 with the official roms (global/eea) and L3 with all other at the moment including china official, xiaomi.eu and all forks.
e.g:
I have L1 with global rom, unlocked BL and magisk.

I'm unlock and rooted, on L1, but u can't install Netflix from play store, so no full HD
I kinda anticipated that, since when you root your device with magisk, Android prevents you from installing Netflix. Which is no problem in my case, since I only watch Netflix on my television or Pc. You can watch Netflix though on an unlocked device if don't root your devices, isn't it?
I just installed magisk and remains L1. Just that the app doesn't appear on play store. Sideloeaded and got hdr working just fine.
i think only SONY has this problem with drm keys and widevine l1..if you unlock the bootloader of any SONY mobile said goodbye to this keys.And the hdr of the camera i think..
I only recommend that you back up the persist partition with TWRP if you are going to change the ROM on the Mi 9T. Some ROMs try to damage this partition and if it does you will Widevine L1 forever as I lost it

Using OrangeFox and there is no checkmark to include Persist to Backup - screenshot attached.
I think it was the same with the official TWRP.
Which TWRP offers to backup Persist?
Btw, I was able to disk-dump Persist:

But read somewhere (cannot find now and didn't try) that Persist.img cannot be flashed through Fastboot (?)

No, but you will lose the safeties that could lead in to a persist partition corrupted.
Backup your persist partition and store this backup OUT of the phone, on a cloud or a PC.

If you will flash ANY different ROM, you NEED to format. since the ROM wont be able to access a encrypted data partition from another ROM/Encryption key.
Also, you can do a forum search for the chinese TWRP, i don't have the link
Good luck.

to backup and
Code:

That's how I did it with my Moto G5+. Later the official TWRP recovery for that device had checkmarks for persist and efs too.

Hi guys,
I have a problem with my device. I recently had a problem with the sensors and I flash the persist.img of fastboot rom with twrp.
I lost WIDEVINE L1 and safetynet checks (only with ROM customs and without ROOT). I would like to know if there is a way to go back and "uncorrupt" the internal storage?

It will flash back to factory settings and reset everything, I would backup and restore after doing so, with widevine though that will stay at level 3 and no chance of getting L1 back ever.

Don't flash persist.img unless it's from your phone, backup with twrp, you could even connect the phone to your PC and copy the persist.img file to your PC and use that if anything happened, the problem is people are extracting the persist.img file from the ROM and it's not the original file for the phone and flashing to correct faulty sensors, this breaks widevine and doesn't restore regardless if a ROM supports it, the phone doesn't anymore because it's now basically corrupt and can't be restored unless using the original persist.img.
I'm not sure I fully understand.
So I've unlocked my bootloader, I'm about to flash Twrp and a custom rom such as Pixel Experience or Havoc.
Am I right in saying this will have broken it already?
Before flashing I should backup everything in Twrp, I can then reviver only the persist part after flashing a room and things will be as normal but with a different rom?
I made a backup of ALL partitions (including the partition persist) 3 months ago that I transferred to my PC and that I later deleted, if I manage to find it with software like Recuva and restoring with TWRP, would it work?

I would say yes if you have the original files, you can try with those, if flashing from stock ROM that didn't belong to your phone then it won't work.

Has anyone tried restoring a twrp backup from a working L1 device?
Can someone with untouched persist that still has L1 upload a twrp backup of their persist partition, please?
It probably won't work as the l1 keys are linked to each device individually but we lose nothing for trying.

Hello,
In your opinion does the xiaomi warranty take care of this problem?
I loos my imei. How i can restore? I have unlocked bootloader..
Efs backup, which you probably don't have. If so try to flash stock ROM with Xiaomi flash
AFAIK flashing the stock ROM won't restore your efs/IMEI...
You have to restore it using QPST and the QCN file (or backup) for the phone model :
https://www.getdroidtips.com/how-to-repair-and-fix-imei-number-on-xiaomi-mi-9t-pro/
However if you don't have a backup then you need to find a QCN file for the 9T/K20 (the one in the tutorial is for 9T Pro), so either have someone with the same phone give it to you or Google it.
I can't find the QCN file for mi 9t only for mi 9t pro...

You could try that but I am not sure if that would restore the wiped DRM keys. In some phones (Moto G5 Plus?), backup of persist from other phones would do no good.
Also you can try flashing stock ROM through AFT and see if it helps you.
An please REMEMBER TO TAKE BACKUP before attempting any of the above methods.

Already tried flashing stock rom via AFT, but Widevine stays at L3. I am not risking to flash persist of other device as it may lead to further issues. Please let me know if there is some more efficient way out of this issue. Thanks.
I heard flashing q firmware permanently causes issues with widevine l1. The only way to bring it back is to restore a previous persist backup or flash a qfil rom (not sure about the latter). If you don't have a backup, too bad chief.

Partially correct. QB1 update caused widevine downgrade to L3 but QB2 restored it to L1. Of course, you have to be bootloader locked all the time. Too many theories going around to restore L1 on UBL but none proven, even persist backup method isn't 100%

Summary of the thread:ANDROID 11 XIAOMI.EU ROMS AS OF CURRENT CORRUPT PERSIST PARTITION.
IF YOU HAVE LOST YOUR PERSIST BACKUP - COPYING PERSISTBAK TO PERSIST IS THE WAY, BUT REQUIRES CALIBRATION AFTERWARDS.
Original post:After spending some time with latest xiaomi.eu weekly I have finally decided to downgrade my phone back to Android 10.
First I've tried fastboot flashing CN 12.0.8.0 with subsequent recovery flash of xiaomi.eu stable 12.0.8.0 which is the latest stable Android 10 firmware.
However, to my surprise DRM Info showed Widevine L3.
Passwords & security -> Fingerprint unlock -> Fignerprint payments -> Widevine (L1) had:
Payment status - Not available
Certificate number - 0
Certificate update -
Pressing Download certificate resulted in Couldn't download certificate. Error code: 1.
Netflix also reported Widevine L3.
At this point I thought that maybe xiaomi.eu didn't have Widevine L1 support for my device back then, so I've tried latest xiaomi.eu weekly which still had Android 10 - 20.7.9.
Unfortunately, same story with that one.
Reading changelogs made me think that maybe support for Widevine L1 appeared only on Android 11 xiaomi.eu lmi releases, so I went for stock firmwares.
I've tried EEA 11.0.6.0 (I think this is the one I've had out of the box), EEA 12.0.3.0 and Global 12.0.4.0 all of which had Widevine L3. The earliest one didn't even have option for downloading Widevine certificate.
As soon as I've updated back to Android 11, I had my Widevine L1 restored, which makes me think that it is impossible to rollback Android version on Poco F2 Pro without loosing Widevine L1.
I've never tampered with persist or persistbak partitions. Maybe flashing persist with persistbak would solve my issues on lower firmwares?
Would be great if someone could confirm that.
So think twice before upgrading to Android 11. Mostly it's about improving DRM (hardware SafetyNet attestation, /data/ encryption, system components wrapped in .apex format files) with lots of features broken on MIUI (3rd party launchers are still kinda broken, though working, they have no support for custom recents menu and default one lags when used with non-default launcher).
It doesn't even have a proper documentation of changes that are required for old applications to work on it (most of them regarding permissions).
Originally my phone was in android 10 with Widevine L1.( V12.0.1.0.QJKMIXM )
I installed EU,Aosp,stock(android 10/11) roms and I always kept Widevine L1.
You may have gone a little too far in downgrade.
Regarding the stock roms, I always used Miflash.(because zip firmware,sometimes doesn't work with twrp).

I've mentioned that, but let me reiterate, I've tried both the earliest (11.0.6.0.QJKEUXM) and latest (V12.0.3.0.QJKEUXM) available EEA official ROM that is still Android 10. Also I've tried latest available Android 10 Global ROM (12.0.4.0.QJKMIXM). No avail.

Not an issue in my case, since as I said, I've been flashing using fastboot, which mitigates recovery altogether.
Edit:
It appears I am not the only one, but it doesn't look like there is a solution unfortunately.

Yeah, I did notice that, but as far as I am concerned, it is not used in the flashing process. Upon inspecting flash_all.bat script I didn't find it mentioned at all!
P.S. Ignore red error message, I didn't want to lock the bootloader, so it didn't get to the checkpoint in the .bat file where it actually does that.

That's true, but it doesn't solve my issue, since I have absolutely the same experience with eu stable and weeklies that are Android 10.

Some people had lost the FOD due to bad handling, only miflash was able to get it back.
Tgz files are much bigger than zips and this is not a coincidence.

After spending some time with latest xiaomi.eu weekly I have finally decided to downgrade my phone back to Android 10.
First I've tried fastboot flashing CN 12.0.8.0 with subsequent recovery flash of xiaomi.eu stable 12.0.8.0 which is the latest stable Android 10 firmware.
However, to my surprise DRM Info showed Widevine L3.
Passwords & security -> Fingerprint unlock -> Fignerprint payments -> Widevine (L1) had:
Payment status - Not available
Certificate number - 0
Certificate update -
Pressing Download certificate resulted in Couldn't download certificate. Error code: 1.
Netflix also reported Widevine L3.
At this point I thought that maybe xiaomi.eu didn't have Widevine L1 support for my device back then, so I've tried latest xiaomi.eu weekly which still had Android 10 - 20.7.9.
Unfortunately, same story with that one.
Reading changelogs made me think that maybe support for Widevine L1 appeared only on Android 11 xiaomi.eu lmi releases, so I went for stock firmwares.
I've tried EEA 11.0.6.0 (I think this is the one I've had out of the box), EEA 12.0.3.0 and Global 12.0.4.0 all of which had Widevine L3. The earliest one didn't even have option for downloading Widevine certificate.
As soon as I've updated back to Android 11, I had my Widevine L1 restored, which makes me think that it is impossible to rollback Android version on Poco F2 Pro without loosing Widevine L1.
I've never tampered with persist or persistbak partitions. Maybe flashing persist with persistbak would solve my issues on lower firmwares?
Would be great if someone could confirm that.
So think twice before upgrading to Android 11. Mostly it's about improving DRM (hardware SafetyNet attestation, /data/ encryption, system components wrapped in .apex format files) with lots of features broken on MIUI (3rd party launchers are still kinda broken, though working, they have no support for custom recents menu and default one lags when used with non-default launcher).
It doesn't even have a proper documentation of changes that are required for old applications to work on it (most of them regarding permissions).

Oho, so what actually happens is that xiaomi.eu roms corrupt persist partition despite that they are flashed using recovery?
And if I don't have persist.img backup, I am basically screwed in terms of returning to Android 10 with Widevine L1 certification? Or is flashing persistbak.img to persist partition would be sufficient to revert the damage? I've noticed that persistbak has much less files than persist.

Not in my case. My persistbak seems to hold its original files, while persist clearly was modified.
Can you confirm how your original persist partition (the one you've backed up) looks like?
Here is a screenshot of my persist and persistbak contents.
