[Help] How to install LineageOS for microG? - Google Pixel 3a Questions & Answers

Dear community,
since last week, I'm trying to install LineageOS for microG on my Pixel 3a. At first, I tried to follow the official LineageOS instructions, which didn't succeed. LineageOS recovery always failed with
Code:
Error applying update: 26 (ErrorCode: :kDownloadMetadataSignatureMismatch)
E:Error in /sideload/package.zip (status 1)
My most recent attempt was to downgrade to an official Android 9 factory release and from there follow the official TWRP guide found on this forum. While flashing the TWRP zip didn't result in any errors, I could boot into TWRP only via fastboot.
From there, I wiped Dalvik/ART Cache, System and data. I then proceeded to Flash the LineageOS for microG zip, which resulted in
Code:
Updater process ended with ERROR: 1
Switching to Slot B before flashing results in
Code:
Error applying update: 7 (ErrorCode: : kInstallDeviceOpenError)
It's the same with TWRP 3.4.0-0 and 3.3.1-1. Vanilla LineageOS runs just fine.
I'm not using nanoxl or Magisk because this installation is meant for my sister and I want it to be simple to use.
Do you guys have any ideas for another method?

mi5 bootloop

Hi, today I installed TWRP recovery and flashed SuperSu in order to flash lineageOS 14.1 on my Mi5 32GB but i got an error.
At the moment of flashing lineageOS, on TWRP's log appeared an error in RED:
"Zip signature verification failed!
Error installing zip file name_folder/.../lineage 14.1-20170228-nightly-gemini-signed.zip". (yes, first of that i did Wipe>>Advanced Wipe>>Dalvik & cache & system & Data and all went fine)
After that i rebooted system and the phone was stuck in MI's boot animation.
Can you help to flash lineage or just recover the phone?
I have access to TWRP recovery and fastboot
Thank you.

Honor View 10 EU Bootloop after Flashing TWRP and [ROM][berkeley][9.0] AOSP Pie

Hello Guys,
today I tried to flash the custom Rom mentioned above because I am tired of that Current Stock Firmware.
The thing is now I managed to end up in a bootloop with nothing working anymore
What I did:
1) I Installed TWRP according to the following guide https://www.the***********.com/install-twrp-recovery-honor-view-10/
2) Because everything was encrypted in TWRP I followed this steps: https://forum.xda-developers.com/doogee-mix/how-to/fixed-how-to-remove-data-encryption-twrp-t3757595
3) The data was encrypted, but every time I tried to flash Magisk it says "Zip file is corrupt" I tried different versions but 15.4 Emui 8.0 should be the correct one but gives me that error.
4) I tried to flash the Rom with TWRP - same error.
5) I tried to flash the Rom using Minimal ADB And Fastboot (ADB SIDELOAD) according to the following guide https://www.youtube.com/watch?v=Oo2cErfUSSE and now I ended up with a bootloop.
What did I miss or where is the glitch in the Matrix here, I dont get the problem
Thanks in advance!
either the Magisk.zip is corrupt or Twrp is not compicatible
after flash Twrp make sure clean the entire system, then flash rom/root by msgisk and do decryption
the proper decryption .zip can flash by twrp is here: https://androidfilehost.com/?fid=5862345805528043263
just clarify your device is BKL-L04 or L09
that is very important!

Invalid partition name :Recovery

Hey guys, just got a NOS One Vision to install LineageOS but when I try to fastboot flash recovery "LineageOS zip"
I always get an error because the recovery partition does not seem to exist.
Then I tried TWRP on external storage. TWRP can boot then install itself: boot recovery from volume down boot up,
but then TWRP always gives an error 255 on flashing lineageOS that way.
Please help!
Just so you know, the phone came with android 9. After my tries, I factory recovered it and it is now at 11
but I did nothing since.
Any ideas?
Update: After letting the Motorola recovery tool upgrade the phone to 11, installing LineageOS went as per instructions

Flashing LineageOS 18.1 after using LOS 19.1 results in fastboot loop

Hello there,
I have some sort of a problem (although my phone is still working.. yet)
I recently flashed my OnePlus 6 with LineageOS 19.1 (coming from OxygenOS 11.1.2.2).
I flashed "copy_partitions.zip" first and then the official LineageOS 19.1 ROM without GApps,
but because I wanted to use some features, which needed at least the presence of Google Services, I flashed the "LineageOS for microG" (19.1) ROM.
Which worked like a charm.. besides I was very unhappy because of the lack of customization regarding color-theming and the changes made to the QuickSettings of Android 12 in general..
So I thought I could clean flash LineageOS 18.1 / ("Lineage for microG") to get the old theming back..
So what I did was installing the official custom LineageOS recovery from 18.1 (because microG had none for 18.1),
hit "Factory Reset" and afterwards applied the Lineage 18.1 zip over adb.
A message "Update package is older than the current build, expected a build newer than timestamp [...] but package has timestamp [...] and downgrade not allowed" along with the Question to install anyway appeared right after sideloading it to the phone.
I decided to hit "Yes" because I don't needed to backup any data from the phone and wanted to wipe clean anyways... (which I thought I did with "Factory Reset)
So I installed and afterwards rebooted to recovery to flash Magisk aswell..
After rebooting to system then, the phone entered the fastboot loop.
No matter what I do, it still doesn't boot to system after installing 18.1 from LineageOS recovery (also tried with the newest microG recovery from 19.1).
I also known you would wipe system, cache and data (and maybe vendor aswell) prior to a clean custom ROM flash (via TWRP)..
So flashed TWRP 3.6.2 (latest) for enchilada and tried to wipe my system, vendor and cache, but didn't manage to find "system" or "cache" on the advanced wipe menu, so I formatted and wiped data and wiped vendor.
Then installed LOS 18.1 via TWRP also..
But same problem - fastboot only.
also after my TWRP journey, sometimes when flashing the LOS recovery and booting it, a message appears on screen:
Failed to bind mount /mnt/staging/emulated/media/0 [...]
The thing is, I can install LOS 19.1 (microG) without any problems and it would boot,
but I just want to downgrade and I found no guide for my device (or any with ramdisk and A/B slots)..
And there is also no link to MSMDownloadTools for Android 10 (because onepluscommunityserver.com is offline)..
The links from this post and some other posts I found aren't working anymore..
- Is there a way to go back to LineageOS 18.1? What would be the intended way (not doing a downgrade but flashing clean)?
- Is my phone softbricked somehow? (partitions broken or corrupt?)
- Is it a firmware problem?
(I am on security patch from November 2021)
But I don't know what exactly happened to my firmware when flashing Lineage 19.1 over OOS 11.1.2.2
This is my first post as it is my first Android phone/flashing experience in general.. so I hope I got everything right from all I found out until now..
I really appreciate any help / even if it is just saying I messed up and need to go EDL mode... (if it truly is the case)
Thanks in advance.
You people are great!
