Follow the instructions below. It doesn't matter what your running if you flash the version listed, it moves you to Andriod 10 and you can then flash the Offical Pixel Experience ROM. I started with a Global ROM that was Andriod 9 and followed the directions and things are running pretty smoothly for me.

Anyone experience problemms with the proximity sensor? While having a call the screen remain black even after i move it from the ear and dont wake up even i press the power button.

PS. And from time to time the double tap to wake doesnt work

How can i go back to miui and lock bootloader without risk of brick?
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] electronique13:
I also have this problem but the flickering was somethings different, it was a huge problem. Appart from that, did you notice sometimes different when flashing from V11 instead of V9.9.25 ? I hesitate to flash again from V11, don't really know if it's going to change something.
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] cywhiz:
At the end, I have to do a clean install to restore my data back. However, I tried a newer build and still the problem persists. After a week, the phone started to act up again randomly. The phone boots up to main screen, however, I can't unlock. The screen just comes on for a second and then it goes black. I used pattern unlock instead of fingerprint this time.

Just wondering if anyone else is having this issue or maybe it is my phone? I don't want to restore data everytime this happens.

Thanks!

Ray could in the next build please change the bluetooth device name string from Redmi K20 to Xiaomi Mi 9t? in the system settings the device name is correct, but in bluetooth it shows k20.

#edit

I just found out the speaker volume is atrocious, on full volume it is about what 40% would be normally, and at half it is basically mute. Tested in spotify, youtube, vlc. Anyone else have the same problem?

Yes but only with always on display

Call recorder.

Hı ı just one ask pixel experience rom have call recorder like miu call recorder ? Thanks.
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] londonhilton:
scratch that audio remark I made earlier, the volume frackass was caused by the Mi enhancer that was on (by default? don't remember turning it on), I only noticed it once I paired phone in my car, and the sound was horrible, turned off the Mi enhancer and everything is fine with both sound quality and volume.
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] _Frostplexx_:
The rom is running great and battery life is amazing, but I experience a strange bug, where when there are no headphones plugged in all videos lag and no sound is playing (increasing the volume doesn't help). This problem goes away immediately when I plug in headphones.

Hi, the fingerprint scanner is too slow !!
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] Octavian87:
Nobody have this problemms? Another Bug is If i call from another phone the call is incoming late after is ringing 2 times on the other phone. I really like this rom And dont want to go back to stock.
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] epraes:
I don't get why people are having so many problems with fingerprints, slowdowns, proximity sensors and other stuff. I haven't faced any of those issues and the ROM is almost perfect.

A bit lacking in terms of features as I'm used to Havoc OS which includes a myriad of options, but apart from that this is a wonderful ROM.

By the way, I followed the instructions the maintainer wrote to a T. I flashed MIUI China 11 (Android 9) through MiFlash and let it update to MIUI 11 Android 10. Then I flashed the latest official TWRP, flashed the ROM, etc.
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] Octavian87:
Come back after a day of usage and you will see
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] epraes:

[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] Octavian87:
Ok then Tell me If You call from another phone to this phone after how many rings You receive the call?
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] timbook2:
So far so good only things I don't like are the AOD it's too bright and don't fade like on other phones and the fingerprint is a little slow. I do like the ROM more than MIUI 11.
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] MalinaBL:

You are using any force doze app like naptime
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] Octavian87:
No not using any app like that. The same its in the evolution x rom. I try it now. I think i am stuck with Xiaomi eu beta for now, even i want pixel expierence rom, i cant stay with this bugs
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] electronique13:
Could you tell me where you found these precise instructions ? The only instructions I find are the one from the first page of the thread

Do you mind sharing them in more details ? Like giving the exact file you used and every step so that we can check if everything works as good as you :) that would be great !

And do you really have 0 performances issues ? Like everything is 100% smooth all the time ? That's amazing
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] londonhilton:
of course he has performance issues, this ROM is working 10fps most of the time, even in slow scrolling text, no images or gifs it is jittery as hell, anybody who says otherwise either has a magical new kernel or is straight up liar.

[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] Octavian87:
You have made any calls? How is the proximity sensors?

I have the impression that everyone who says everything goes perfectly does not use the phone as a primary phone. Over the problem with the screen that remains closed after closing the call can not pass and I did a test with the call from another phone and after ringing 2 times on this then the call appears on xiaomi mi 9t

This two bugs are very important to me
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] luisgerardo01:
I use it as my principal phone: personal and work. Call ringing perfectly. No problems with sensores, no lag, no FP slow. I receive all day calls from providers and nobody has tell me problems with audio.

Coming from Xiaomi.eu, had to wipe everything (except vendor and internal storage) and format data then. Installed latest China MIUI ROM, finalized the setup assistant, reboot and then installed newest firmware, PE ROM and Magisk. That's all! Regards!
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] electronique13:

MIUI 11 Features in Pixel Experience

Good evening. I have a doubt. I use MIUI 11's print screem a lot on android 9 by swiping my 3 fingers on the screen and sending. I also use call recording and notes during a call. Will it be possible to have these functions in Pixel Experience?
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] chikiro:

Hi, I was wondering if someone can help me getting VoLTE and VoWifi working on this rom please? My understanding is that both are supported ok.

For the life of me I can not get them working.

I have confirmed that my sim can access both features as I put my sim in my wife's Nokia 6.2, the VoLTE logo came up ok and I could make a call over both VoLTE and VoWifi.

I have attached a screenshot showing the mobile data settings.

Any help would be appreciated.

Settings keep forceclosing on me even after today's update and cache wipe, what the hell is going on, anyone else having the same issue?
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] lvtz:
That's because you did something wrong in the installation process. Probably you skiped to format data. We can see this every day with people who don't want to loose their data. But you have to. And if you don't, you will facing issues.

So again, find below the whole process step by step.

1. Boot to TWRP (official one)

2.

WIPE

all except Usb Otg

3. Install Miui 11 Android 10 (V11.0.2.0.QFJCNXM)

3.

FORMAT

data, and then reboot to TWRP again

4. Copy PE zip into /sdcard

5.

WIPE

Cache and System

6. Flash the PE zip

7. Wipe Dalvik/Cache

8. Reboot system

That's all. All working good after that.
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] londonhilton:
dagnabbit, I did not did anything wrong, I did format data and flashed everything as it ought to be on 24th or when was the xmas release, everything worked fine, settings worked fine, then there were one or two ota updates, settings worked after that as well, last time I tried was maybe 3 days agot o check if there aren't updates via ota. for the last 2 days settings keep crashing, after today's update as well.

Experiences with PE (20200101)

I flashed the ROM which was updated to 20200101 since then (the installation process and the OTA update done without any problem).

The software seems OK, I have only two issue:

1. The fingerprint reader: it does not recognize my samples many times (I have added one fingerprint multiple times, but it did not helped). With the original ROM it was problematic too, but works better.

2. The double tap: wake up the screen with double tap sometimes not working, and when it is, it's very slow (with the original software it was fast and accurate).

AOD

Some experiences and suggestions about AOD:

I use the AOD always turned on mode. When I put the phone in my pocket (or cover the proximity sensor) the AOD turns off (which is OK). But when I take out it from my pocket (not covered sensor) the AOD does not turn on again (which is NOK, I think; I need to turn on/off the screen to switch it back).

It has one benefit, I can easily turn off the AOD for night. :)

It would be useful if the AOD could be scheduled (turns on only from 6AM to 10PM for example).
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] Amsterdamvrn:
Auto brightness

Auto brightness works very poorly. Sometimes after unlocking the screen it is 100% and is not adjusted until the screen is re-locked. In low light, the brightness level periodically increases and decreases. At the same time, the actual level of illumination does not change. Firmware from 01/01/20. Short video with auto brightness bug

True. It worked better a few days ago.
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] lvtz:
Sure! Find steps below:

1. Boot to TWRP (official one)

2. WIPE all except Usb Otg

3. Install Miui 11 Android 10 Stable (I have European version, so i installed this one : V11.0.1.0.QFJEUXM But for global outside EU you can use this one : V11.0.1.0.QFJMIXM)

3. FORMAT data, and then reboot to TWRP again

4. Copy last PE zip into /sdcard

5. WIPE Cache and System

6. Flash PE zip.

7. Wipe Dalvik/Cache

8. Reboot system

And yes data are lost. You can save them before flashing your phone.

[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] luisgerardo01:
How did you enter into TWRP? Through "fastboot boot recovery" command or it's already installed in the device? Because whenever I loose my TWRP installation I need to flash TWRP before flashing any ROM because of encryption. Maybe you didn't format data before too.

---------- Post added at 04:06 PM ---------- Previous post was at 04:04 PM ----------

Hope you didn't wipe "internal storage" if so, you'll need to use MiFlash utility before. Happened to me in a Mi A2 device.

---------- Post added at 04:10 PM ---------- Previous post was at 04:06 PM ----------

I use Gravity Screen to workaround sensors sometimes working and sometimes not. At night I just cover the sensor and the AOD turns off. By now, I'm fine with this until sensors work.

No matter what I do, I end up in a bootloop after flashing PE. It has been over a day now and it is getting extremely frustrating, what am I doing wrong?
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] tegazinho:
That's probably caused by your twrp, I had the same problem, apparently formatting data with other twrp's that are not the chinese one, sometimes makes your phone in bootloop. You will probably need to flash the latest miui again using the mi flash tool, and then restart the process of installing the twrp and flash the rom you want.

Follow this simple recommendation, my FOD works great on the latest build. I used vendor from latest stable EU 11.0.1.0

DELETE ALL FP AND REGISTER AS FOLLOWS:

Register 2 times each fp in a way such that you press your finger `gently` and mostly the tip portion of your thumb [do not press the whole thumb flat place it at an angle such that your tip of thumb covers most area]

After this your fp should perform much better and do note that while unlocking the phone too press gently and don't press thumb flat instead use it's tip mostly
[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] spitzmk1:
Hey there, thank you for this ROM.

I have 3 questions:

The fingerprint unlock is a bit slow for me and does not always recognize my fingerprints, it's far from the efficiency in miui 11. Will it be improved?

The sound it makes when front camera is selected, will it have an option to disable it? It's kind of annoying.

Is the "Now Playing" feature gone from Pixel Experience ROM?

Thank you
