PS: I no longer use the phone due to its many problems.

Anyways, I managed to install TWRP on the stock system image. I did this by flashing the TWRP image with the pre-rooted GSI and rebooting into bootloader mode (download). After that, I flashed the stock system image by extracting the AP file and then compressing it to .tar via 7z. After flashing, I booted into recovery and flashed the multidisabler.zip and then wiped Cache, Data, and Dalvik. I rebooted my phone after that. No security check errors, All okay. I tried to reboot into recovery the 2nd time and Twrp is still there. Also, flashing Magisk won't root the device, you will still end up in the same security check fail screen, even if you reflash the stock boot image, It won't go away (prob bcs of twrp). You will need to reflash the stock ROM for it to go disappear.

There's another bug on my phone that I haven't found any solutions yet, on phone calls the phone doesn't have any audio input or output (microphone & handset/speakerphone). But WhatsApp calls work just fine. Does this also happen to your device?
I've tried fixing contents through TWRP but it didn't fix the problem

I have this issue too, I tried everything of my knowledge but didn't work, seems like a Treble issue with Qualcomm sdm439/sdm450, except this, everything seems normal to me.

    Okay this version works, but I seem to encounter a problem. Everytime I try to open Storage in Settings, the Settings App crashed, and whenever I try to install an App from Play Store, it says that I don't have enough storage. Does it have something to do with this on the original thread?

    It's a common issue. Try following these steps:
    1. Boot into TWRP
    2. Go to Advanced
    3. Click on Fix Contents and confirm
    4. Reboot

    I thought I made mistakes throughout the process so I tried re-doing everything from the beginning and it finally works without storage issues. Thank you so much for your help, especially pointing out the correct OS image, such a lifesaver

    Hi, may I know which version of LineageOS did you install?
    I've managed to successfully flashed LineageOS ( lineage-19.1-20221122-UNOFFICIAL-arm64_bgN-secure.img.xz ) but my phone keeps rebooting while setting up.

    you downloaded the wrong version. you can find it at https://sourceforge.net/projects/andyyan-gsi/files/lineage-19.x/History/ and make sure to download lineage-19.0-20220211-UNOFFICIAL-treble_arm64_bgS-vndklite.img.xz use ctrl + f to find it faster. and then flash it again, and it should work perfectly fine.

    also if you want root permissions make sure to install phh superuser, flashing Magisk will brick your device.

    Hello, I've been trying to install LineageOS on my device (SM-A207F), and I've followed every instruction so far, but I'm stuck while trying to flash heimdall sysnull.img

    After I typed in heimdall flash --SYSTEM sysnull.img in the terminal, I've persistently got this error:

    Session begun.

    Downloading device's PIT file...
    ERROR: Failed to receive end PIT file transfer verification!
    ERROR: Failed to download PIT file!
    Ending session...
    ERROR: Failed to send end session packet!
    Releasing device interface...

    I've unlocked the bootloader and enabled USB debugging.
    I'm using Ubuntu 22.04 LTS (on VirtualBox, Windows 11), also very new to custom ROM, I've only successfully installed LineageOS on an S5 (SM-G900H).

    Use Dualboot instead of VirtualBox, you can find tutorials on youtube but you'll need a spare USB drive
