Hello
I installed successfully Lineage OS with the google apps add-on. I have been able to install all google apps I need except one : maree.info.
I asked the dev who said I might miss a package like Google Services or Google Licence, etc.
Anyone can confirm if he can install that application or if he also get the problem (google say not available for that device)?
how can I track what is missing and solve the problem?
Thanks for your help

LOS 20 has been released thanks to @ceracz for his hard work maintaining our phone!

Is it possible to dirty flash LOS19.1 (unofficial) over LOS18.1 (unofficial)?
What would be the steps to do so?

Official LineageOS needs to be installed cleanly... There is no easy way to upgrade Los 18.1 to 19.1 or 20...due to different signing keys.

 

[psychofaktory]

So could there be a "not so easy" way here?

I have found posts on other requests of this type on the Internet that a migration script was used that was then flashed together with the new ROM with the new signature keys.
I just don't know how to create such a script.

I would like to change from LOS18.1 (unofficial) to LOS20 (official).

Are there any additional steps to install LOS 20, comparing to LOS 18?

Read precisely official install guide... There is a switch to dynamic partitions.

Hi, It's been some time since I have participated in XDA.

I'd like to submit bug reports for LOS20, but I'm not sure where I should do so.

I have noticed that connecting to some bluetooth speakers is troublesome. Phone doesnt connect to bluetooth devices unless the wifi is turned off and on again.

Also the High Quality Codec switch seems to have problems especially for LDAC. When turned on for LDAC the sound comes from the phones speakers loudly, not from the bluetooth speaker. To play from the bluetooth speaker, I turn off ldac, turn off wifi and Bluetooth, restart the speaker, qnd then connect through SBC.

Additionally auto brightness seems to fluctuate a lot, especially indoors. I can describe details and attach logs if a quality of life fix is possible.

@ceracz The official installation guide says

> Before following these instructions please ensure that the device is currently using Android 11 firmware.

What exactly does that mean? My MI 9 Lite only gets MIUI Global 12.0.10.0 (QFCEUXM) which is based on Android 10 (QKQ1.190828.002). I could not figure out any way to get Android 11 via official ways.

What do I need to use to get to that FW version? There are ROM files available to download...most of them I cannot install when using the official updater (via selecting 'Choose update package') as it fails to "verify the package" denying the installation. How can I get the Android 11 firmware, is it really necessary before installing LOS 20?

Thanks for helping!!

Thanks @ceracz ! Are there any known issues about the ROM on pyxis? I am going to flash it soon, but I wanted to check first whether there is anything known that does not work with the OS?

Nope, Lineage-20 has the same feature set like the Los-18.1. The difference is only that 20 is Android 13 and is official.

If you want to use MIUI camera that is integrated in Los 18.1 there is a flashable module that can be flashed after installation of the ROM.

You can find it here:

since i could not find that info:
Can you go back to stock after installing Lineage 20? Not sure if something changed from Android 11 to 13.
DDG tells me me that on other devices a downgrade seems possible tho.

Thanks! I'd like to suggest to add this info or a link to this post to the guide at https://wiki.lineageos.org/devices/pyxis/install, that would've saved me some time searching

***Update
I was able to install Lineage 20 after flashing the recovery image that was provided with it.

I have TWRP version 3.5-1.A9-19-03-2021 by geoanto555 and I used it to install Lineage OS 18.1 on my Mi 9 lite half a year ago following the instructions of the fist page.

Now I'm trying to install Lineage 20 using the same method and I'm getting the following error:

Target: Xiaomi/pyxis_eea/pyxis:11/RKQ1.200826.002/V12.5.3.0.
RFCEUXM:user/release-keys
.assert failed: update_dynamic_partitions(package_extract_file("dynamic_partitions_op_list"))
Update process ended with ERROR: 1
Error installing zip file 'external_sd/lineage-20.0-20230513-nightly-pyxis-signed.zip'

Hey, I'm having in the exact same situation as you were. Could you tell me the steps you followed to complete the installation? Because the original guide from LOS didn't work for me...
