Widevine L1 on stock - Redmi K20 / Xiaomi Mi 9T Questions & Answers

I was playing with Mi 9T custom ROMs (LineageOS, Xiaomi.eu; Russian TWRP) and kept getting a notification saying my persist parition is corrupted.
I flashed persist.img from the official EEA 10.3.12 fastboot ROM And everything seemed to be OK. But even after flashing to stock and relocking the bootloader, the Widevine certification is only at L3.
As I understand it, the persist partition included some keys used to decrypt L1 DRM content. Is there really no way to get L1 back? Even with Magisk?

You can install this Magisk package => https://forum.xda-developers.com/mi-9t/themes/magisk-widevine-l1-fix-xiaomi-eu-roms-t3962506

did you find any fix.?

No I didn't. I even contacted Xiaomi support team for help and was told that MI 9T is not L1 certified anyway so they cannot do anything.

[Firmware] 4.0.2 Firmware flashable update zip

Just grabbed the firmware files from the latest 4.0.2 release (same pack as someone else uploaded for 4.0.1, I just replaced the files with the newer versions.
Here is the 4.0.2 :
https://www.androidfilehost.com/?fid=673368273298924614
Here is the 4.0.1 if you decide to go back:
https://www.androidfilehost.com/?fid=529152257862696316
So far I've noticed a marked improvement in GPS satellite detection, it's almost instant (I'm on official RR and it had been mentioned so folks on RR might want to try it for that reason).
Wow this is great. Cause gps is kinda bad....

If you're already on OOS, why not just update the ROM to OOS 4.0.2 instead of only updating the firmware?

That's a common issue and not related to the firmware, try installing the latest version of TWRP from their website, it was just updated yesterday, there's plenty of posts about dm-verity.

You must have made a mistake while unlocking your bootloader then, I'm not getting any issue and I'm on the same platform as you (3.0.3-1 and RR), no one else has made any similar comment either (It's been downloaded and presumably installed 72 times). Did you follow the guide in the TWRP thread? (Wipe data partition, etc)
Does this latest firmware still trip the DM-Verity error on boot?

What mistake? Fastboot OEM unlock that's all. After Than fastboot flash recovery twrp.img. Previously i was do adb sideload Because dm-verity Was show on Oxygen 4.0 when I rooted Rom. When dm-verity gone i flashed RR remix on twrp 3.0.3-0. Everything Was ok. Yesterday a flashed twrp 3.0.3-1 and newest RR remix. Today i flashed 4.0.2 firmware and wrrr dm-verity error showed up. . I will backup this Rom Than i will try flash Oxygen 4.0.2 full an twrp 3.0.3-1 or adb sideload.

It should be 4.0.2 cos it's the files from that release, did you get any errors when flashing? Remember, it's not the full 4.0.2 rom so if you're running the OOS 4.0.1 you should really just run the official update, to be honest these files were just for when it first came out, any more recent custom roms should now include this new firmware in them, if you're running a custom rom.

What is the problem you have?
I just go to official Magisk topic and download Latest Magisk (version 12.0), flash it through TWRP (i'm using 3.1.0-0) and when the phone is on go too Magisk Manager at Play Store and install it.
After going through that, it just works... :silly:
Ok, I am going to try it. Thanks

I have read recently that CTC verification now fails due to unlocked bootloader, as well as it's other detections like root.
I read on the Netflix/root thread on XDA (sorry don't have link. It was on main page this past weekend) where several people mentioned that.
I'm trying to find out if relocking bootloader , can I keep twrp and root (magiask) ?

On stock rom root cannot be hide.
I tried magisk and supersu+suhide.
You can flash the newest Resurrection Remix.
Su hide and cts are OK.

widevine l1 with unlocked bootloader??

As the question implies, what happens with widevine l1 if you unlock your bootloader?? My new redmi note 7 is global and has widevine l1 want to know to see if I unlock or not
it becomes L3 for sure
It becomes L3. I reflashed the official miui rom without relocking and it's L1 again.

I think I'm just going to flash the official updated miui rom, my redmi comes with carrier software and it's lagging behind in updates.
I have the global variant (the PFGMIXM one) with unlocked bootloader and I still have L1 certification. Rooted with Magisk too.

How to get back to stock and locked BL?

Hi!
I'm currently on Xiaomi EU beta, MIUI 11, android 10. I'm going to sell this phone and want to go back to stock global and then locked bootloader. I need some help. Tried downloading xiaomi flash tool, but I get an error message when trying to install drivers. Can I just flash the fastboot image of MIUI 10 global stable? Or will there be any rollback problems? Can I flash the .zip in the chinese TWRP?
Hoping for some answers. thanks

I can't tell you if it will work without issue... I think the best solution is using "Fastboot" method.
Be careful not to trigger Anti RollBack protection (ARB) when downgrading, this could brick your smartphone.

Ah yes it seems that if you flash through xiaomi tool or fastboot there is a check before flashing the ROM that can be rejected if the RollBack index is incompatible. Just avoid flashing an older miui version from TWRP, or check the RollBack index before. https://www.xda-developers.com/xiaomi-anti-rollback-protection-brick-phone/

I didn't know they had the same ARB version, but I just wanted to warn, you have to be very careful when performing a downgrade. If I had to downgrade, I would check the ARB index just to be safe. There have been devices bricked before because of ARB on Xiaomi devices according to this article https://www.xda-developers.com/xiaomi-anti-rollback-protection-brick-phone/ and others. Better safe than sorry.
