Widevine L1 after bootloader unlock + root with Arter Kernel? - Razer Phone 2 Questions & Answers

I was curious if anyone has Widevine L1 after doing a bootloader unlock because I do use Netflix quite often. I'd personally would like to keep Arter's Kernel and Magisk for ARCore support plus other fixes that require root. There wasn't too much information in terms for the Razer Phone 2 specifically, not even sure if flashing back to stock and relocking would 100% restore Widevine L1.

How to get Widevine L1

Hello,
i'm still on Nougat. To get DEX working i flash notorious kernel but i noticed that my N950F have now only Widevine L3
Before i try that kernel i had Widevine L1
What can i do to get both?

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

Xiaomi.eu without Root but Magisk, still Widevine L1?

If i unlock my bootloader, install the Xiaomi.eu Rom and Magisk but DON'T root, will i still have Widevine L1?
Unlock= L3
Is there a Magisk module to fool it?
More discussion here: https://xiaomi.eu/community/threads/widevine-l1-netflix-15001-error.49716
Seems like L1 status has been working at some points and some people have been able to resolve issues
Your best bet is probably using the patched Netflix linked on that thread

[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.

You should never had to flash Persist.
AFAIK (google around), by flashing Persist (even your own), you irreversibly lost L1 and forever
Is there any way I can revert it back?

You had to flash the stock firmware as tgz/fastbook (not just as zip/recovery).
And tried: Settings, Passwords and Security, Fingerprint unlock, Fingerprint payments, Widevine L1, Certificate update
But I doubt you could do it now after playing with your Persist
I already tried that, nothing seems to work, can service center restore L1 manually like oneplus 5t required Manual loading of widewine L1 from service centre

[INFO] Widevine L1 Support
This thread should answer most of your questions regarding Widevine L1 support on your device(s). I will try to keep it maintained and up-to-date. Notes: * This list includes only supported Android 10+ devices that either support Widevine L1 officially, or support it unofficially by Xiaomi.eu...
xiaomi.eu
You can try service center if your bootloader is locked and is still under warranty coverage.
