Question Recover Widevine L1 is possible ? - Samsung Galaxy S21 Ultra

Hello
My phone is rooted and with the bootloader unlocked. So isn't possible to watch any streaming app in HD.
If I relock the bootloader and flash a standart ROM without root. Can the Widevine L1 be recovered ? Or once the "e-fuse" is set to 0x1 cannot longer be recovered.
Thank you in advance

You dont need to relock your bootloader just flash a stock rom without root. On my galaxy 20+ Netflix runs on L1. On my Galaxy 21U with root just L3

unlock bl but keep full resolution Netflix?

I recently learned that an unlocked bootloader will trigger the Netflix app to only play in standard definition but not HD anymore because of Google Widevine DRM going from L1 to L3 even with Magiskhide. Is there any way around this on the Mi 9?
From my experience the only way is to relock your bootloader! :/

Thanks, for confirming that. I wanted to help my son unlock and root to install the Viper audio mod. But losing resolution on Netflix because of it is a deal breaker for him. Pity!
How do you even get a proper Netflix app, I got Mi9 Transparent edition with unlock BL, but the app says my device is not supported by the app

Have you tried installing the Netflix app from a another source than Google play?
The mi 9 I was asking about has a locked bootloader and Netflix installed from Play store. Given the consequence for the resolution of Netflix playback I won't unlock :-/
Perhaps a silly comment, but has anyone tried rooting and using magisk hide to perhaps allow regular playback? I can't cos 1. The phone hasn't arrived yet and 2. I don't use Netflix! Just came across this thread and wondered if it would make a difference...
I unlocked my Chinese MI 9 and flashed the official Global ROM. Now Netflix doesn't show up in the app store anymore, nor does it run when I install it manually.
As a temporary work around I installed a modified Netflix app that was made to enable HD playback. This works now, but I don't know how long this will last - so I'd be interested in a permanent solution.
Since I went from Chinese to Global I cannot lock the bootloader again or it will brick my phone.
How would Magisk help with solving this problem?
Also, can I install Magisk without TRWP or wiping the device?

If you can provide us the link to your Netflix MOD app it would be great, anyway i think you can go back to chinese to relock your BL, Magisk does nothing, i'm on global rom with magisk no Netflix available

Unlocking the BL without root won't change L1 to L3....! If the device is the Global one...

Yes, it is the global one. I thought the security downgrade was linked to the bootloader. Any way to root without detection??? My objective is to install the audio tuning app viper4android which needs root access.
Hi,
I have find a solution to get widevine l1 working with unlocked bootloader. With Beta 9.6.27 the drm Info App Shows widevine l3, Then i have flashed the latest xiaomi.eu Rom 10.2.16.0 root it with magisk and now the drm Info App Shows widevine l1 so now you have Netflix and Others Apps with hd Resolution. Bootloader is unlocked

Wide one is for TV streaming, not for the actual HD playback on the phone I think

Netflix Widevine L1 Lost After Downgrade Android 10 to 9 and Flash persist.img

I tried Android 10 and I decide to downgrade my Mi 9T Pro to Android 9. After downgrade, so many things broken because of persist.img
So, I reflash the persist.img (from V10.3.17.0.PFKCNXM) file and problems solved. I am using xiaomi.eu_multi_HMK20ProMI9TPro_V10.3.17.0.PFKCNXM_v10-9 now.
Netflix Widevine is turned from L1 to L3, so I cant play HD or HDR contents. How can I fix that?
once you have modified the vendor/persist partition (flashing the vendor/persist.img through twrp) there is no way to recover widevine L1 except for having to change the equipment for a new one or with a change of pcba
And if you try to flash using EDL? and then tell us if it is possible to recover the widevine L1

EDL doesn't help. What is pcba?
you could try format data with twrp, then you install xiaomi.eu

You should backup your stock persist. L1 is gone forever now so far I know.

I have a Global device. Unlocked BL and flashed the Indian version using fastboot. Haven't rooted but I have formatted all the partitions from twrp before fastbooting the indian rom.
Problem is now I cannot download Netflix app from the Playstore and figured also the playstore "Device is not certified" there in settings.
I want to know this is common and there's no way to get Widewine L1 when BL is unlocked? Or is there a possibility if I go back to the official Global rom and lock it?

Just flash magisk and safetynet patch module, then delete play store data. You can install Netflix now.
Just wondering, what are other disadvantages aside from loosing L1 ? I also flashed my persist image on A3 due to downgrade and sensor problems. Will service center be able to flash to restore it? Cause the phone is running fine on anything else
Same Issue with me. Any progress on your situation OP?
Maybe you should have done some research before doing something that stupid. Flashing persist.img is guaranteed to make you lose l1 permanently.

Tencent edition problems

Hi I have Tencent edition and I received it with WW rom with WW fingerprint with 1908.12 version. Safety nets passes but few things is not ok. In DRM info I have Widevine L3. I've tried to flash rom with unlock and lock bootloader but still have L3. Unlock app dont work , i unlock bootloader via ed.

If the bootloader is unlocked widevine will be L3. Only relocking, which will remove root and wipe data will give you L1.
Asphalt is just a preinstalled system app, part of the ROM, you can remove.
I have done relocking and dont have prompt on booting.

What do I lose when I open the bootloader Redmi K20 Pro

Hi everyone
Question for professionals and experienced people I hope to get a reliable answer on this matter
1- What do I lose when opening a bootloader other than air update and payment and warranty service?
2- Is it possible to return to the official status and receive air updates?
Thanks everyone in advance
Can't say for sure but you should still get OTA; if not you'll get full ROM zips delivered via OTA instead of the smaller chunk/patch updates.
The main thing is banking apps and Google Pay. Widevine should be OK. On mine it's L1 so still A-OK for Netflix/etc.
OTA updates work also if bootloader is unlocked. Idem for payement and warranty service...
If you root the phone it isn"t the same story.
Mine is rooted and OTA updates work. I download the update BUT I unroot the phone before installing it.
It"s possible to relock the bootloader but no need to do that...
PS: Unlocking bootloader resets the phone (Back up what you need before).
Unlock bootloader means no more hd on netflix n stuff.
Widevine stay L1 but netflix will failed to load unless you delete smthing n widevine drop to l3

Read carefully the forum! It seems people had problems by flashing a wrong global rom. I can't help you more because I've got MI9T Pro and didn't read a lot about that.

[REQUEST] DRM info after relocking bootloader

From the title: I'm kindly requesting to check DRM status (DRM Info app here) after unlocking bootloader and after relocking the bootloader.
If possible with a screenshot otherwise I'm interested in knowing if Widevide DRM Level goes back to L1 after relocking and how System ID changes with L3 and L1.
Furthermore t's useful knowing if you also flashed a custom rom and/or blew Knox Fuse in some other way.
Disclaimer: do not unlock your bootloader just to do this check. This request is meant for people who already have bootloader unlocked by their own means.
There is a screenshot example attached to this thread, stock locked A71 never before unlocked.
You keep your DRM keys when unlocking bootloader on A71, so Widevine stays at L1.
No TWRP installed, only magisk.
oh, that's actually really good news.
My previews experience with Widevide DRM was a permanent keys loss.
Thank Samsung for this approach.
Should I be warry of some particular step into installing magisk on A71 ?

Not really. I rooted by mixing magisk into android and then flashing it with odin. There are some tutorials on youtube, showing how it's done.
