Question Unlock bootloader Oneplus 9 Global/NA

[velocitysages]

Has anyone unlocked the bootloader on oneplus 9 global? how to not lose Widevine L1, because I have tried many times but every time I unlock the bootloader my Oneplus 9 always loses L1 and it changes to L3

AFAIK there's no way to keep L1 while the bootloader is unlocked.

Yes. I'm unlocked and L1. You have to use magisk and zygisk to hide . Then l1 occurs.

Yeah I have Widevine L1. I rooted C.48 global with Magisk 24.3, hid Magisk, installed Shamiko (because it's better than denylist), and installed Universal SafetyNet Fix.

This is for the 9 Pro but it's the same process (you will want to check both the 9 and 9 Pro forums because the 9 Pro is more active and devs will often just drop their thread there for both devices).

I have keep L1 by unlocking bootloader from latest Oxygen OS 12, without flash magisk, only unlocked bootloader. L1 will change to L3 if you unlock bootloader from Oxygen os 11
