Widevine certificate and ROM switch.

Hi,
After unlocking my boot loader SafetyNet pass failed, and some application like Netflix disappeared from the play Store, Fine. My widevine L1 certificate was still valid. and I had been able to install netflix using an APK.
So first question, Is my netflix APK setup allow me to watch FullHD steam ?
Currently My ROM is MIUI Global 12.0.3 Stable, If I switch to any other ROM, I will loose my L1 certificate, correct ?
A MIUI Europe ROM may keep may L1 ?
If I switch back to MIUI Global 12.0.3 Stable I will get my L1 certificate back ?
For now SafetyNet Failed ctsProfile, and evalType is locked to HARDWARE.
I also have a redme Note 9S on which I install pixel experience, an SafetyNet Pass, but my widevine is an L3.
Uriel,

Thx, I find this post yesterday in the morning, but I was not able to find it back in the afternoon.
A read it again, and after applying the hardwareoff_1.1 script my SafetyNet switch to basic, and is now passing.
I'm still concern about is Xiaomi.eu will loose my L1 certificate.

Make a backup from thr "Persist"-partition and save this on your pc. If you lost your widevine L1 you can flash the persist backup, and L1 will be back.
NEVER flash a persist img from an other user or phone!
You can pull easy the persist.img through terminal emulator or in ofox with the inbuild emulator.
Command is: dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist.img

Hi,
I'm currently using Pixel experience on my Poco X3 NFC, my L1 certificate is still valid, and SafetyNet pass in BASIC.
Nice.

Widevine L3 to L1

I just downgraded my NFC global from A11 12.5.1 to A10 12.0.9 due to the fact that A11 is buggy and I can't even play with my phone anymore, after successfully downgrading the phone to A10 with the update and rename method I noticed that the widevine certificate is L3 rather than L1 and I can't even watch Netflix because of sd crap. Is there a way to restore the widevine L1 while staying on A10?

Question Lenovo TB-J716F: Keeping Widevine L1 when rooting

Hello everyone,
it seems that it's currently not possible to root the Lenovo XiaoXin Pad Pro 2021 (TB-J716F) and keep Widevine L1 at the same time. Once the bootloader is unlocked, the tablet seems to lose Widevine L1 and falls to L3.
As soon as someone finds a way to root the device and not lose L1, please post it in this thread.
Thanks a lot! Have a nice day

I have had some luck with some Magisk modules on my Xiaomi Mi 9T pro which is unlocked, rooted and still has L1. I will post the modules I installed when I get home so you can try it.
EDIT:
Universal safetynet fix by kdrag0n
MagiskHide Props Config by Didgeridoohan
Not sure if it supports this tablet yet but I think there's a way to copy your L1 devices fingerprint and then put it on the rooted/unlocked one.

Thank you, I will check this modules for compatibility. It is hard to get the official ROMs currently, so I'm not going to "try & error" at the moment.

Is it possible to restore L1 on a locked/unrooted device when one doesn't have the original QCN file anymore?
(I did "reset all before download" in QFIL configuration)

Sorry, I didn't try to root so far.

Question Restore stock fw + widevine

Hi guys
I just bought my P11 pro from AliExpress with the not so good global ROM and unlocked bootloader. Also, L3 widevine.
Is there a way to put the stock fw back and restore the widevine L1?
Is the stock fw better than the global fw?
Thanks in advance

Install Stock ROM - Xiaoxin Pad Pro 2021 [TB-J716F]
How to install Stock ROM - Xiaoxin Pad Pro 2021 [TB-J716F] I tried installing a GSI-ROM on this tablet, which basically worked except for three/four bugs I coulnd't solve. So I tried to restore the Stock ROM in the meantime and will share my...

Thanks! I read it but still got questions.
Is the stock fw fully translated to English?
Re-installing the stock fw will allow for OTA updates?
Is there a downside to the stock fw?
Also, as I can understand, there is no way to restore widevine L1 once the bootloader has been unlocked. Does anyone know anything about that?

English is my native language and the Chinese ROM on this 2021 Pad Pro 11" is actually pretty decent. I have no translation issues. There are a few apps you will want to disable and you will have to manually install the play store but once you’ve done that it works fine. Its fully google certified and Netflix etc shows up in a search. I use Nova Launcher rather than the Lenovo launcher which I would also recommend.
Mine came with the Chinese firmware so I didn’t have to do any messing about and my widevine L1 is intact, I have received x2 OTA’s an I manually flashed to update to ZUI13. I believe other people eventually received those updates via OTA as well.
I’m sure I’ve seen people on the thread who have successfully flashed back to the Chinese ROM, locked bootloader and regained Widevine L1.

I can confirm this.
I recently ordered the P11 Pro from bangood.
This also came with a outdated global ROM and Widevine L3.
After Installing the Chinese ROM with above guide and locking the bootloader I got Widevine L1.
I hope this helps.

That's great! How did you relock the bootloader?
I was able to reinstall the stock fw witch already received OTA update to ZUI 13 (yay!)

I used the script shared by Tropaion in his post on how to unlock/lock the boot loader:
https://forum.xda-developers.com/t/lock-unlock-bootloader-xiaoxin-pad-pro-2021-tb-j716f.4347321/
What is important is that you have to install ADB fast boot and for me I also had to install the lenovo driver shared by zeroflame15 in his reply to the post:
https://forum.xda-developers.com/t/...n-pad-pro-2021-tb-j716f.4347321/post-85850437
When you have all drivers installed all you have to do is run the script and follow the steps.
I hope this helps!

Thank you guys!
I was able to re-lock the bootloader and restore widevine L1
Turns out that even though I have the L1 certification, Netflix , Amazon and Disney will limit the quality of the streaming because it is a portable device. No HDR on Netflix too... Bummer. Still, I managed to install stremio and get the quality I pay for.

That's odd. As you can see in the screenshot attached I do have the option to stream in full HD via Netflix now. You might want to try reinstalling Netflix via the Google play store as this should now also be certified. (At least it is for me) HDR capabilities I am still missing however.

You can get Dolby Vision on the P12 but as you say HD only. Stremio is the way forward. I have kept my subs live for use on the TV but at least we can watch in full quality in bed.

Widevine L3

After new year or 11.0.5.1 update, widevine certificate went from L1 to L3. I never unlocked, rooted or modded my phone. Model is Oneplus 7 Pro GM1910 256gb. What is your widevine level?

Same for me, although I am not sure of the timing. Ever find a fix?

Try flashing latest OOS 11 image from MSM tool. Internet says it fixes the L3 issue.
Note:
1) Flashing ROM from MSM tool will wipe data so backup first.
2) The image necessarily needs to be Oxygen OS 11. Version 10 won't fix anything.
I have this issue as well. But I am living with it as I don't use Netflix stuffs. Let the community know if it fixes
