[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] AzureusPT:
I've just flashed LOS 19 on my phone and it works really well, but I'm unable to install Magisk successfully.

I've tried patching the boot images either directly (getting the image from the device via dd) or using the one inside the lineage-*.zip payload file. The patch appears to complete successfully as well as the flash of the boot image, but upon restart Magisk will display Zygisk as No and some entries in the settings are grayed out (I suppose for the absence of Zygisk).

I've also tried renaming the .apk to .zip and flasing it via sideload. The only error I got was the one regarding its signature, but upon restart its the same, Zygisk appears as No.

Also I flashed vbmeta with the flags requested by the installation process.

Is this the actual behavior over LOS 19.1 or do I need to perform any other step in order to be able to have Magisk working?
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] R!ffRaff:
no problem here with magisk, but i use lygisk for ota update
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] KardingVerdugo:
Can anyone share the battery experience with LOS 19
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Emeraldawn:
Developer options, status bar location indicator.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] AzureusPT:
I can confirm this on a fresh LOS 19.1 install. Once Android Auto is setup in both car and device, the next time you plug the phone in it works depending on the following:

If the phone screen is locked, the screen turns on, you can see a notification for Android Auto trying to start, but it ends in an error. In my case the phone displays a notification from Android Auto telling that it wasn't possible to start AA and to check the cable.

If the phone screen is unlocked and you plug in, AA starts normally.

In my test the cable was obviously the same, so there might be some glitch or issue there.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] CHGICEMAN:
@AzureusPT

This is exactly the same message as mine.

Maybe you can confirm that here too?

I noticed that under settings>display>colors there are only 3 options instead of the 4 of 19.1. Not sure if this is the intended behavior.

Is AudioFX working on LineageOS 20?

It isn't on 19.1 and hasn't for a while (19 and below)

Last 20.0 build is pulled due to issue with proximity sensor. Will be fixed from next build.

For existing users, you can flash attatched boot.img, extract from the zip file.

[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] CHGICEMAN:
@althafvly

I'm not very proficient in flashing *img files. Which adb command do I have to take? Can this also be done via sideload?

For example: "adb Sideload boot.img"
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] sharkfins0up:
Yes. My bad. The setting is there. just in a different spot
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] sharkfins0up:
Thanks. I found it. It was in a different spot
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Barracuda77777:
on linux from boot loader:

fastboot flash boot_ab boot.img
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] CHGICEMAN:
Sorry for the stupid question. I need to reboot into fastboot and then type the command "fastboot flash boot_ab boot.img"?
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Barracuda77777:
providing that you have linux and you have installed fastboot, yes you will need to reboot into bootloader to flash, then once flashed type "fastboot reboot" to restart your phone. ,make sure you are in the same folder where you saved the boot image, or else you need to point to the location of the file..

there are many how to flash boot image just use the search function.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] CHGICEMAN:
For all those who want/have to flash the Boot.img from Windows ;-) here are a few instructions.

Boot into fastboot mode.

Open cmd as admin.

Go to the folder in which adb is located and where the boot.img file is best located.

Enter the following command:

"fastboot flash boot boot.img"

When it's done copying and writing, type: "fastboot reboot"

After that, your proximity sensor will work again. thanks to althafvly

[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Smultie:
Yeah, I know.

But the 19.1 roms took about 2.5-3 hours.

Just curious what's causing the difference, is all

I am downloading or installing it. So now it's official again.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Smultie:
With the previous release (which was later pulled back), the thread was just renamed. So no new thread expected.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] pajicadvance:
Update is out, downloading right now. In the first LineageOS 20 release that was pulled, I had the following issues:

Proximity sensor not working properly (said to be fixed in the new update)

Fast charging not working

Camera taking low quality photos in 4:3 aspect ratio regardless of the used camera app

Will report back on what got fixed and what didn't.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Smultie:
Currently installing too.... is it me or does the "Finalizing package installation" take even longer than usual?
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] pajicadvance:
You're right, it is taking forever. Weird.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] CHGICEMAN:
1) Proximity sensor works!

2) Fast charging works

3) Unfortunately, photos in 4:3 are not taken with full resolution. In 16:9 already.

4) The CPU is now running at full power again.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] damonke:
same in gcam? might just be the new camera app in 20
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] pajicadvance:
Fast charging is still broken for me. It says that it's charging rapidly on the lock screen but AccuBattery still reports sub 10W charging speed.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] pajicadvance:
Yes, the same problem exists with GCam.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] CHGICEMAN:
I only use the gcam. But the problem still persists with another one.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] CHGICEMAN:
For me it's just 13W but my battery is full right away.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Smultie:
Hm, I just noticed my CPU was running full speed already before installing today's update. Could it have been fixed in the boot.img posted last week?
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] pajicadvance:
So, the previous build was pulled due to having issues with the proximity sensor, but distributing a build that has broken fast charging is acceptable? What's the thought process here? When is the Bugs section in the original post going to get updated to reflect this?
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Smultie:
Lol, one reboot later I don't see 3.2 GHz anymore. This thing is a bit of a mystery..
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] CHGICEMAN:
Go to the display, then lock screen, and there you will find the item, "Wake the display on pick up".
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Smultie:
Can't confirm what?

Just did another reboot. Right after the reboot it shows 3.2.

Not much later it won't run @ 3.2 any more. It's like its throttling and doesn't ramp back up to 3.2 after having been throttled.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] CHGICEMAN:
It makes a difference whether a basic function, such as making a call, no longer works due to the proximity sensor, or whether you have to wait a bit longer and the battery is better protected.

How full was your battery? I think it needs to be pretty empty to charge at full power.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] pajicadvance:
It is stuck at 9W no matter how full the battery is. It has been like this since the first LineageOS 20 build. On LineageOS 19.1 it was always above 20W no matter what.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] CHGICEMAN:
Funny that doesn't happen to me.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Smultie:
What program do you use to see the current cpu speed and what do you do to get the CPU to ramp up fully?
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] CHGICEMAN:
CPU-Z app. I don't do anything to make it work.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Smultie:
Haha, just tried to replicate while filming.... thing keeps ramping up to 3.2

Like I said: bit of a mystery!

What I wonder about this upgrade instruction:

Is there really no need to flash a new vendor_boot.img first for the new LOS-Recovery since the ROM is based on Android 13 or is there no recovery change necessary?

Edit:

Btw. I did not stick exactly to the official upgrade recommendations. I did the vendor_boot flash & sideloaded the new FW-package as ZIP from yshalsager's Xiaomifirmwareupdater via ADB. Way easier and faster than extracting out the stuff from the whole Package an install the images one by one. Don't know why that's not recommended. The pacakges from yshalsager are well established since years and work flawlessly.

But just to make sure everything worked - could anybody tell me please the baseband Version of Poco F3 after the Update to LOS 20?

[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Smultie:
Yup. Had one too. Was road cycling with my phone in my backpocket. Was surprised my Bluetooth (podcast) stopped all of a sudden. Turned out to be a random reboot.

[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] m-snel:
I have the same problem with the fingerprintscanner.

Installed completely new: boot, vendor boot, LOS20 for Poco F3 global, Mind the GAPPS for android 13 (and just to be sure also copy partitions). Everything works and a fingertprint scan is made (and stored) only to be empty (erased) after a reboot. Reinstalled several times but every time the same problem.

It seems the Trusted Execution Environment is reset after a reboot or something.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] CHGICEMAN:
I don't understand why everyone installs the individual files separately. Take the "LineageOS install package" as written in the instructions and install it. Then the firmware beforehand. Gapps and done. That's how I did it without deleting anything beforehand and it also works with the fingerprint.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] m-snel:
As test now installed boot 19.1, vendor boot 19.1, LOS19.1 for Poco F3 global, Mind the GAPPS for android 12 and now the fingerprint gets stored and remains after reboot.

Wil do that now and report my findings.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] CHGICEMAN:
Why so complicated? Everything is included in the package.;)
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] m-snel:
Don't know. Always starting clean (with placing back the backup from Google drive once a year with a new version and then do all these steps https://wiki.lineageos.org/devices/alioth/install/variant1 including factory reset). I have 2 Poco F3's available (always good to have a backup if one gets stolen, or I dive into the water with it or something) and switch them every year (that's why I can now test without any problems because my other phone still on 19.1 is still my main).

But just had 19.1 on the device everything worked great fingerprint wise. Now did only adb sideload LOS20.zip and Gapps13.zip, factory reset and setup fingerprint which will work untill reboot then no fingerprints are stored anymore.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] G A S T:
Thank you for your confirmation. That looks good. I have TKHEUXM and my baseband is now

2.5.c1-gl-21664.2-0301_1352_eeada84be8.

So everything should have worked fine for both of us.

@CHGICEMAN:

You're right. Therefore I recommend:

0. flash latest vendor_boot.img as very first (only optionally)

1. adb sideload FW.zip

2. adb sideload LOS.zip

3. adb sideload MTG.zip

Have fun with the upgraded LOS 20-Device.
