How to get back to stock and locked BL? - Redmi K20 / Xiaomi Mi 9T Questions & Answers

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

You can try to flash "Recovery" ROM image and flash it via TWRP yes.

I tried to run it as administrator. Still the same error. It wouldn't be a problem downgrading from miui 11 to miui 10 just by flashing zip?

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.

Ye, that's what I'm afraid of.. But what if I use the xiaomi tool and flash the fastboot image?

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/

Wtf? MIUI 10 and 11 have the same ARB version. What "brick" are you writing about?

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.

I never pretended to know whether the ARB index was different or not, I just said it would be a good idea to check. Thanks for bringing your huge knowledge in and giving us more information!

SM-G9280 lost imei and baseband

Dear all,
My phone can boot on but reboot after 1 or 2 mins due to lost imei and baseband. It had worked till I updated to 6.0.1 (with firmware download from Sammobile) and run CF autoroot and many things more, sorry I cant remember whole process. My fault is not make EFS backup before doing anything.
It can boot into recovery (TWRP3.0.2) and download mode also. I know my imei, any chance for me to recover it back and make the phone work?
At least, any advice how to prevent it to reboot?
Many thanks,
Anyone using a g9280 phone could give me a working efs backup?? Thought it can help.

[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.

You can do nothing. You need to get on Marshmallow because you installed a wrong version.

hi guys. I updated my p9 lite the same way (proxy finder) but after the update I made a full data wipe and now I have no keyboard and I can't bypass the google account. And because of the full wipe i don't have the recovery to flash the 2nd .zip file to enable the other apps, so im stuck :-s. I´ve tried to flash the .zip file via dload method but with no results. Can you help me?? thanks in advance

First of all I know my English is really bad but anyway..Is your bootloader unlocked? If so you can just install twrp and flash the zip file. And if it's not.. You need to get into fastboot mode in order to unlock it and install twrp.. And to do that you need to first turn your phone off then plug in your charger and quickly press and hold the power and volume down buttons before the screen turns on.. Now you're in Fastboot mode..Now search on Google or xda how to unlock and get the bootloader unlock code..and install twrp for nougat..you know.. I don't know if you can find the nougat twrp here on xda but I think you can get it​ from htcmania.com :victory: I hope that helps

Widevine L1 on stock

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
