[Q] Will installing custom ROM allow keeping L1 Widevine? - OnePlus 6 Questions & Answers

First moment I got the phone, I unlocked bootloader and root the phone. I notice that my video looks crappy and I can't pick higher resolution. Does installing custom ROM allow L1 Widevine or is that tied into the bootloader unlock?

Soon as you unlock, you drop to L3. No way around it for now.

Widevine DRM, Level 1, and Root

As the title states, is there a way to get this going?
I picked up a OnePlus 6 which supports L1. Once I rooted the device it appears to have dropped to L3. Is there a way to keep root and have L3? The only instance I care about this for is YouTube TV. It's not so much the resolution but the frame rate. 60 FPS content isn't available unless you're at 720p minimum and L3 only gives you a maximum of 480p which is at 30 FPS. I tried searching couldn't find any topic of discussion.
Is my only way to get back to L1 to unroot and relock the bootloader?

Unfortunately yes. It has nothing to do with root, but Widevine L1 requires a locked bootloader on all android devices. More detailed information is available here. Seems like it would make more people more likely to pirate the content since they can't use the services they actually pay for like Netflix, Amazon, Google, etc; but I that's DRM for ya.
Yes and no. I've got a device which have L1 and unlocked bootloader to gain root. All fine.

Device motorola Z3 China version. Flashed to Verizon ROM. Then simply unlock and flash magisk-ed boot.img. Interesting that unlocking bootloader does not break Widevine L1.
I've lost my widevine L1 certification after Oneplus 7 Pro 11.0.1.1 update. PLEASE HELPPP

L1 DRM with unlocked bootloader

Currently I am on stock OOS with a locked bootloader and I heard that when you unlock the bootloader the DRM gets downgraded to L3.
Is this correct and does it go back to L1 if you relock the bootloader?
Also, is there a hack of some sort that allows the device to continue using L1 DRM with an unlocked bootloader?
L1 not working
I unlocked bootloader and then relocked it again but it is still showing L3 what should i do

You can try to flash magisk to pass the saftynet and hide netflix/amazon prime video to try HD content

Ok so it is reversible
But there is no way to get L1 with an unlocked bootloader?

What I've seen by now, no it's not possible.

Ah ok that's unfortunate
I'll probably stay with official OOS for the moment anyway, but thanks for the info
So, has anyone tried OOS 5.1.6 and the fastboot locked bootloader bug to backup and restore the DRM keys while locked or to use Magisk root while on 5.1.6 locked bootloader and see if L1 keys are retained?

There's another thread in this forum that poses that exact question. No one to date has succeeded and I'm not sure it's even possible using the 5.6 boot exploit because Widevine calls home every time it proxies protected content.
I suggested chipping in on a bounty that would go to whomever can find a way to get L1 on a OP6 with its' bootloader unlocked using a method that would be successful with ROMs based on OOS, LOS and AOSP. I figured a little financial incentive could provide some motivation, but nobody else seemed willing to contribute. ?

Since I need L1 on an unlocked bootloader, I ended up getting a Moto Z3 Play despite it being slower since Widevine L1 stays regardless of bootloader state or Magisk being installed.

Unlock vs Root & Widevine

So i know rooting the device will result in losing Widevine DRM L1 certification, but does unlocking the bootloader do the same? If it doesn't, (dumb question incoming) are there any mods you can do to the device without root?
unlocking the bootloader will result losing widevine not the root.

Keeping both

So i can't keep both root and streaming Netflix in FHD?
Cuz i have unlocked the bootloader and just like that it triggered the security patch.
So I'm here seeking ways to keep both.
no way to have both (root and hd) If you unlock your bootloader for root you lost Widevine L1 for hd capability. You have to make a choise lol

Question Is it possible to reach widevine 1?

Hello,
I received a P11 Pro 2021 with global rom and open boot loader, I was able to change to CN rom, update and close bootloader but I am not able to reach L1 in widevine.
Now I am in last rom with android 12, with bootloader locked and still widevine L3, is there any method to download or flash again the keys to reach L1?
It is a pity to have this hardware and have to watch streaming platforms in SD.
Is it posible to contact Xiaoxin to receive widevine keys again? some brands like Xiaomi have this option in the system.
Thanks for your support,
Mee too facing same problem. Mine used to have L1 but after an update downgraded to L3
As I can see, nobody has been able to upgrade from L3 to L1. I had hope on last update but with no luck.

I read somewhere, that if you relock bootloader with anything else flashed on your device other than original manufacturer FW, you are pretty much risking hard brick ... so consider yourself lucky, that the only consequence of relocking bootloader is degraded Widevine security level...
If you feel that you must have L1 on your device, you can try to flash your device back to original manufacturer FW and then relock your bootloader again, theoretically you should have L1 security level back (I may be wrong, because I have not tested this personally)...
I have tried to lock and unlock in almost every possibility and I have almost bricked several times.
But, isn't suppossed to work out of the box with widevine L1 and stream in HD?
Not sure if you did factory reset after either reflash, but if you didn't, it's worth the try, of course at your own risk ...
And if you didn't already - read this thread, may be an inspiration for something untested on your side...
If you received original tablet (not secondhand, or tampered by the seller), I'm 99% sure that if you flash FW, which put manufacturer on it when it was produced, you will get L1 security level back.
If you have secondhand device or from AliExpress, or from China and seller flashed Google Play Store for you, etc., AFAIK then unless you'll find out what FW exactly was flashed on your tablet in the factory, you may not get L1 back...
But, I'm not expert at all, and I do hope somebody else will provide better solution for you...

If you have root and magisk, you can try to install safetynet pass, shamiko and then try to spoof your device with some module from cyberelon on GitHub. I didn't try it yet on P11 Plus, but I am using instantnoodle module on my M10 FHD Plus and Netflix is running with L1.
