Clean flashed (see previous message). Works perfectly. Haven't encountered the previous issue where the phone would just hang after a while / heavy usage. So far it's ' bug free ' .

And how does one do this when nandroid backups aren't possible with Android 12? Flashing ROMs suddenly becomes like Russian Roulette.

You can still do a "data" partition backup.
If you want to replay it, then first install the ROM (zip-file) via TWRP and then reestablish the data partition from your backup.
For me this worked fine.
Therefore I have no problem in testing other ROMs and getting back to the former state.

I tried to do it, through the built in updaterr. couldn't decrypt data (password incorrect) (TWRP 3.6.0_10 surya).
I tried too.

So I had 0502 19.1 along with the 0502 Leneage Recovery. I updated through the OTA feature. It rebooted to the Lineage recovery and flashed the update.

After that it rebooted and I got boot loop back and forth to the Loneage recovery asking me to format my data.

Oh well, I've read here that versions after 0502 will have to be flashed clean because there was an issue with the updater.

Now I'm on 0516 I hope I won't have to clean install the next one.

But thanks to OP. Really appreciate your work here.

Xiaomi Poco X3 NFC
Something is messed up with telephone service, keep spaming green location dot every couple minutes
It's not messed up, that's a feature. Telephone service is using location constantly probably because of Nearby feature or something similar + other factors.
The issue is that it prevents showing the location indicator for other apps as it's constantly occupied by location access of Telephone services.

It's blacklisted aka fixed on ArrowOS. It's just the matter of time & will if LineageOS will fix it too.

So what's the consensus on the new LOS ? Upgrade or too new so better stay with 18.1 ?

I hear the new Arrow also its share of issues and the changelog says it's still using blobs so it's not a firmware thing I guess

After dirty flashing the 2nd 19.1 update through lineageOS recovery (ADB sideload) and sideloading Magisk afterwards, I can say after 2 days of usage, I haven't had the freezes that I've encountered before with the 1st build.

It's too early to say. I'm on the latest version for two days now and had them once since.

    @v44r I asked Alessandro (MindTheGapps' author) and he released a new build, in case you want to try it
    Thanks. I tried that version (because the addon.d script in NikGApps failed when I tried to update to latest LOS) and now my app works without problems. Calls to GoogleApiAvailability.isGooglePlayServicesAvailable() now return 0 and subsequent calls to Wearable.* work as expected.
    Is it possible to pass safetynet with ih8sn? (without Magisk)
    I was following this manual for OP8:
    But I need the ih8sn.conf file for our Poco X3 NFC (surya).
    Has someone passed safetynet with this method?
    It seems a new unofficial/test build has been released yesterday "to fix freezes" (from Telegram), download is at https://www.gardiol.org/surya/test/

    LineageOS 19.1 Official (18.1 discontinued as of 2nd May 2022)

    We are official!

    17.1 will never be official (and it's upstream dead)
    18.1 is official, discontinued builds.
    19.1 is official and built weekly.

    * Your warranty is now void.
    * I am not responsible for bricked devices, dead SD cards,
    * thermonuclear war, or you getting fired because the alarm app failed. Please
    * do some research if you have any concerns about features included in this ROM
    * before flashing it! YOU are choosing to make these modifications, and if
    * you point the finger at me for messing up your device, I will laugh at you.

    What's working:
    • WiFi
    • VoLTE
    • VoWIFI
    • FM Radio
    • RIL (telephone, SIM, 2G/3G/4G/LTE/+/blah...)
    • Tethering
    • Bluetooth + AAC
    • Tethering + bluetooth working
    • Safety net passed
    • SELinux Enforcing in Trust
    • DT2W
    • WiFi Display fully working
    • Infrared (IR)
    • NFC (Surya only)

    Known issues:
    • Honestly at this time, nothing?

    Camera Notes
    ANX camera is not recomended and will most probably NOT work.
    To get a fully working camera try one of the gcams here.
    Do not forget to copy&load the associated xml file!

    Official LOS uses oss camera service, so xml written for other custom roms might not work.
    The gcams at the above link have modified xmls for LOS.


    There is also a MIcroG build if you don't like Google Apps!
    If you care for official microg builds, check here they will be ready when they will be ready, those builds are not done by me nor supported by me, do not ask me about it.

    There is also, for help and support, the:
    • Make sure to flash at the very minimum firmware (anything newer will work) from XiaomiFirmwareUpdater firmware page
    • (For 17.1 <<only>> : flash VENDOR + FIRMWARE from Android 10, do not use Android 11)
    • Download this build and Magisk (optionally) and gapps (optionally).
    • Put the zip on your MicroSD (suggested) or connect via USB to PC.
    • Boot to recovery (latest TWRP only is suggested! OrangeFox has issues).
    • Wipe Dalvik, Cache and format data. This IS NOT OPTIONAL!
    • Reboot recovery after wipe and format.
    • Flash this ROM zip...
    • ... flash gapps zip ...
    • ... If you want Magisk, flash zip ...
    • Reboot and enjoy!
    If you have any issues flashing, like persistent GApps or booting issues, try to cleanup the phone with the following procedure:
    • Download a full MIUI rom recovery package from XiaomiFirmwareUpdater MIUI page
    • ... (make sure you download the full rom package for RECOVERY, it is about 2.4Gb!) ...
    • From recovery, flash the zip file. This will cleanup all the partitions.
    • Now flash again this ROM.
    This problem is related to the fact that TWRP and OrangeFox both don't support dynamic partitions properly yet.

    Tested with Magisk 24.1, newer version should work, but you MUST follow the SafetyNet fix guide in the next post if you want Play Store certification.

    Suggested GAPPS for LineageOS: Mind The Gaps (here, make sure to download the ones for your android version 10, 11 or 12).

    Additional notes

    SafetyNet does not pass by default, you need to follow the steps on post n.3 below. This is due to Google issues and LOS rules.

    Passing SafetyNet and Google Play Certification

    SafetyNet and Play Store certification

    (guide updated 01 feb 2022, for Magisk 24.1 and Zygisk)

    LineageOS, by charter, does not alter any safety ptotection set by Google. In our case, having an unlocked bootloader, safetynet will always fail by Google decision. Now, passing safety net is required for banking apps and even some games. Also, it is required for "play store certification", which will prevent you from even searching for some apps (like Netflix).
    Blame Google for all this.


    Install Magisk

    Download latest stable magisk apk from Magisk website (https://github.com/topjohnwu/Magisk). Rename it as .zip and flash it from recovery. Some recoveries, like TWRP, will flash the apk directly, others will require the rename.
    Boot LOS and install the apk file.

    Hide Magisk apps and Enable Zygisk & blocklist

    Open Magisk App, go to settings and hide the magisk app. Give it a name you will remember.
    After magisk app has been hidden, go back to settings and enable Zygisk (beta).
    Now apply the blocklist and select all the apps you like NOT to detect Magisk. This must include Google Play Services and Google Play Store.

    Install SafetyNet fix module

    kDrag0n developed a fix that can be flashed via Magisk. You must download the module (https://github.com/kdrag0n/safetynet-fix/releases), select at least version 2.2.1, and install it from inside Magisk app.

    Setup Fingerprint

    Download latest Props module for Magisk (https://forum.xda-developers.com/t/...t-prop-edits-and-more-v6-1-2.3789228/page-274) and install it within Magisk. Reboot your phone.
    Now, after reboot, open a terminal (use "adb shell" from pc, or install termux from play store) and type:
    su (grant root access!)
    props (a text based menu will popup)
    Now select "1" (edit fingerprint), type "f" (pick fingerprint) select "22" (poco) then select any one poco x3 model. Which one really doesn't matter, but make sure to choose the right Android version.
    Confirm and reboot phone.

    Clear caches for Google stuff

    Now, open settings - apps and clear data&cache for Google Play Store and Google Play Services.
    One last reboot!

    Don't want root?

    If you dont want root... Just disable it from within Magisk!

    OPTIONAL Additional stuff

    Magisk from 24.1 removed the built-in modules repository. If you like it back, you can install Fox's Magisk Module Manager app (https://github.com/Fox2Code/FoxMagiskModuleManager).

    I have some news. I am working on Lineage-18.1 and so far i am having some good progress.
    I managed to boot it, it's still unstable and a lot work is required, but it's steady.

    It is OSS based, so this will be official no doubt this time.
    Official build is again underway and will be ready in a few days.
    Everything has been approved this time we are just waiting for hudson & wiki merge to be approved.

    I think there is good hope that the first official build will be next week.
