Flash the latest TWRP 3.3.1-42 Unofficial by mauronofrio. You will not lose your data. It can be downloaded from here: https://xdaforums.com/Mi-9/development/recovery-unofficial-twrp-xiaomi-mi-9-t3905825.

I experienced the same problem after upgrading to Android 10 (TWRP did not ask me to enter my decryption key). I then flashed the latest TWRP 3.3.1-42 Unofficial by mauronofrio and the problem is now fixed. Give it a try.

Hey there, just flashed this but after bootign I got this issue. As far as I know it means my device is locked? What do I have to do here? I've tried to unlock it with my number but it was not working.

Some of my apps no longer work on Android 10. The GLTools app which made it possible for me to permanently display the frame rate of a game in the top right corner of my phone's screen and also allowed me to increase the screen resolution of my games does not work in Android 10. I use to be able to overclock my phone's GPU to 810 MHz using an app called 3C CPU Manager. With Android 10 I can no longer overclock the GPU using the 3C CPU Manager app. Also, some of my games will not work on Android 10, etc.

Flashed the recently released 9.10.31 and was surprised with Widevine L1.

Can someone confirm that this is no coincidence? Didn't checked my Widevine level directly before flashing but last I checked it was L3.

[Xiaomi Mi 9 Guides, News, & Discussion] hnz101:
Unfortunately I can't really remember. Some (EU-ROM) Pie release, I flashed as soon I could unlock. :)

But I don't think that this should make any difference except perhaps it's an China device.

[Xiaomi Mi 9 Guides, News, & Discussion] ToneLa:
It is not pre rooted.

I dirty flashed the newest version (to take it up to Android 10) and lost TWRP and root!

No big deal, was able to put it back with Fastboot, and Magisk

But now I'm experiencing little bugs... one crazy one, I connect to my work wifi and it crashes at the "enter password" page you get to log into the wifi! It reboots to recovery! If I don't see my work wifi login page (and it is fine with my home wifi), it will stay on all night... crazy

So I think I will do it again, non dirty!

Some notes:

- Swift Installer is not working on Android 10, on this ROM.

- However I used Substratum with the Swift Black theme perfectly. Substratum is a bit different now, you need to build each app first, then you MUST reboot, and can only enable when you come back in.

new November build is up! I've dirty flashed and everything's running great so far. After some time on aosp roms I came back on revolution os because It's the most stable and debloated rom I've found. Sadly few people seems to try it. Even if I would prefer Aosp roms, I they ain't stable enough so far for me, all of them have some bugs or drawbacks compared to miui.
[Xiaomi Mi 9 Guides, News, & Discussion] rudge79:
I've also tried AOSP ROM and experienced the same thing. Normally I would use AOSP extended. This time it was too buggy.

This ROS rom is the most stable and good battery life. For this year there the last update for ROS OS will be between 24e and 27e of December.

It takes forever to back up all the data on my phone and restore it since I'm not rooted.
[Xiaomi Mi 9 Guides, News, & Discussion] rudge79:
I tried the first time installing ROS. It can be done but it's not great. You do not exactly know if everything works and can't verify if all bloatware is out.

Android 10
[Xiaomi Mi 9 Guides, News, & Discussion] ToneLa:
I have no such issue, at a guess did you dirty flash? You get no end of strange little quirks sometimes when dirty flashing.

It seems to differ by country but basically you can unlock the bootloader without voiding it. It is the custom ROM flashing that voids it... but such software changes, you can roll back (IE, back to stock).

I think the official software for unlocking the bootloader will tell you anyway. It'll try to scare you :)

It's Android 10! :)

So how can I get the Always On Display to show notifications? I like the clock and it shows battery % but never notifications even though I have Notifications set to On in the theme I choose there, and individual apps are configured right

No, i deleated all data, format data and i do a factory reset. Any Idea?
[Xiaomi Mi 9 Guides, News, & Discussion] rudge79:
Have you checked if the accelometer works correctly? Maybe it's broken. Else try to install a different firmware that is compatible with ROS. Maybe that might work.
[Xiaomi Mi 9 Guides, News, & Discussion] Herbie17:
in ROS 11/10/31 everything is fine, in newer Roms, ROS, Xiaomi.eu, Global Rom or Mi roomRom the auto Rotation didn't work
[Xiaomi Mi 9 Guides, News, & Discussion] ToneLa:
Hmm, seems to be a permissions issue. Every time I reboot, one of the apps I have tried, Always On Edge, has its permission reset!

I've tried to exclude it from the power management but no joy.

But it's weird how the built in screen-off with the clock is SUPPOSED to show notifications yet does not.

A Google suggest it's a common issue with MIUI / Xiaomi
[Xiaomi Mi 9 Guides, News, & Discussion] rudge79:
It's all about permissions indeed. MIUI is very very strict in showing alerts en popups on the startscreen. It's a kind of MIUI layer of strict permissions where few is allowed.
[Xiaomi Mi 9 Guides, News, & Discussion] krusir:
If you still have rotation issue. Flash persist.img from the same base of fastboot rom. This should get it working.

The new ROS is out 19.12.24!!!
[Xiaomi Mi 9 Guides, News, & Discussion] krusir:
Tried 19.12.24, upgrade from running 9.11.23. Loop back to twrp. I tried uninstall Magisk and redo it again. Still the same.

I tried flash boot.img extract from 19.12.24, still loop back to twrp. Flash again 19.12.24, still loop back to twrp.

I then flash 9.11.23, it boots up fine. I am planning to try upgrade again.

I notice that state in ChangeLog, we are move base to "Stable MIUI" since 12.24 build. Will this make to start from fresh as requirement.
[Xiaomi Mi 9 Guides, News, & Discussion] rudge79:
I had the same problem. Solution for me: format Data partition.

Since 9.12.24 cannot write to /Data for some reason.

If you do not format /Data you will get stuck in bootloop.
[Xiaomi Mi 9 Guides, News, & Discussion] rudge79:
See this statement of BadWolf
[Xiaomi Mi 9 Guides, News, & Discussion] krusir:
rudge. Thanks for the confirmation. I don't like to format data unless I have to.

I notice that it boots fine after flash MIUI 11 Stable xiaomi.eu_multi_MI9_V11.0.5.0.QFACNXM_v11-10.zip. I did re-flash 9.12.24, again won't boot. I am going to flash again of latest MIUI 11 Stable and keep it for the timebing.
[Xiaomi Mi 9 Guides, News, & Discussion] krusir:
I am wondering, if it is the "change base to stable" which require "format Data", why it boots fine with the latest stable which is xiaomi.eu_multi_MI9_V11.0.5.0.QFACNXM_v11-10.zip.

I was hopping that if this stable boots up fine, I can then refresh the ROS 12.24 build. Not in the case.
[Xiaomi Mi 9 Guides, News, & Discussion] 1Ton1886:
I won't be upgrading to the latest version of Revolution ROM (9.12.24). Formatting my phone's data just to upgrade to version 9.12.24 is a ridiculous requirement.
[Xiaomi Mi 9 Guides, News, & Discussion] tosonny:
However you like it. But otherwise I think it would be your latest ROS version....no updates for you then.
[Xiaomi Mi 9 Guides, News, & Discussion] rudge79:
I would recommend titanium backup. The directory of the backup is best kept on your pc/laptop and you are ready to go! Root is needed (magisk canary).

The ROS version 19.12.24 is stable and smooth. I find it worth the effort.

Edit: also as far as I can understand from now on OTA updates should be working for new ROS roms to come. So that means quick and easy updating from now on.

Which Gapps version did you install? You got to take aroma I guess. Maybe you can also check if all needed permissions are granted. Settings-->apps

Didn't install any gapps, never done with revos. I just thought it wasn't needed because everything works. Should i install any specific version?

Btw, if i delete cache for Google app and then i record enroll "ok google" again, it works for a little time only. Strange issue, I'm not able to solve.

Also, all permissions given.

[Xiaomi Mi 9 Guides, News, & Discussion] rudge79:
I'm sorry, you are right. No need to install Gapps it's already in this ROM. It should work out of the box. You only need to activate Google Assistant I think. I must say I never use ok Google.

[Xiaomi Mi 9 Guides, News, & Discussion] tosonny:
How can you say such stupid things. Think a bit...if this would be a rom issue there would be tons of complaints. It works very well. That's an issue of your installation / flash procedure...that's it.
[Xiaomi Mi 9 Guides, News, & Discussion] Jppv:
I have had older version of this rom for 6 months on my Mi9 and it is one of the best roms I ever had. Everything works well, batteru lasts, etc. Dont know what is wrong with your setup/installation, but ROS is solid.

If the rom would be bad/broken, there would be lots of complains about it...
[Xiaomi Mi 9 Guides, News, & Discussion] hfaz63:
I spent the whole day trying and talked to them on their English Telegram group but ultimately it was futile as the ROM would not work as expected for me :(:(
[Xiaomi Mi 9 Guides, News, & Discussion] tosonny:
Maybe you think a little bit about what your posting up means for many others who are only in this thread? A misinformation, because the rom works perfectly. If you have troubles, announce the circumstances, that, if I remember correctly, you didn't format your phone the first time, maybe it was because of the Chinese version of the hardware, that it is a specific problem of YOUR phone is and not a general rom problem. It is no wonder that those in the Telegram Chat are not very happy with users who do not read / follow the clear instructions first and then express themselves in this way. They would rather "go to another rom" than bite into it and help for hours. They are very restrictive.

I did with (TWRP 3.3.1-52 Unofficial by mauronofrio):

1) format the phone

2) flashed the rom

3) rebooted once and did some minimal setup

4) rebooted in recovery and flashed magisk

...I have never ever flashed this DFE-stuff (don´t know why it is not needed ...because it is recommended). And all works.
[Xiaomi Mi 9 Guides, News, & Discussion] rudge79:
Give me one hour with your phone and it is fixed if it ain't hardware related.

I would format each /data /system partition. I start with formatting it again with ext4 fs. Flash TWRP from Maurino version 52 and start all over again with the correct procedure.

Many errors are caused by conflicts in vendor or firmware from previous Miui roms. Rebooting several times is also recommended. And do not flash everything at once.

Also some people still believe that 'wipe' is the same thing as 'format'. Well it ain't.

This rom is close to perfect. Believe me I have flashed a lot of other roms around.
