[WARNING] OOS11 MESSES WITH WIDEVINE (HD QUALITY VIDEO)

[trueToastedCode]

If you install OOS11 11.0.1.1 and want to go back to OOS10, then your L1 level is gone for Android 10. It comes back when upgrading

Wow, even on locked bootloaders? That definitely sucks.

My bootload was unlocked when i downgraded to locked OOS10 with MSM. But that was no issue before 11.0.1.1. I've done that and still had L1 on 10. In combination with what is in the official OP forum i dont think the bootlaoder is the problem ;(

This is not a general issue. I myself had 11.0.1.1 installed with unlocked bootlaoder and was able to revert to OOS 10 without any issues. Bootloader locked and Widevine L1.

Maybe it is related to the MSMDownload Tool variant you used. Which one was it?

I used the one for 10.3.8 Global (on EU device).

I used the one for 10.3.8 Global (on EU device).

I did that several times also having an EU device and never ran into this issue. Pretty weird and worrisome...

So weird... i mean how can L1 be on 11 but not 10 ;((( I'll try now to unlock and lock on 11 and then downgrade to EU 10 and wait more then 24h with biometric auth activated.... Probably its also they way i am installing the driver for MSM ... (i leave the driver uninstalled until the disconnect sound appears, then without the driver installed the device does still not reboot... then i installed the msm driver - device does not auto reboot like that with driver installed) Lets see... i now installed the driver before it was connected and pressed start directly


Update: Not working.
