[RECOVERY][UNOFFICIAL] TWRP for Galaxy S10 (Snapdragon)

Search This thread
Hello! I noticed that the Snapdragon variant of the Samsung Galaxy S10 (SM-G973U) has an officially supported TWRP page on twrp.me. They note that this device uses DM-Verity. They say that one should flash a customized kernel that has dm-verity disabled in the fstab. My question is this: if I download the vbmeta_disabled.tar file available on this thread, will flashing it to my device disable dm-verity on Android 12? I ask this because the customized kernel that I could find for this device (Cruel Kernel) was only available for the Exynos variant, while I have the Snapdragon variant. Thus, I am not able to flash a customized kernel as twrp.me suggests.

You dont need custom kernel and official twrp was for android 9
And if your bootloader not unlocked you cant use both.

    Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

    Code:
     * Your warranty is now void.
    * I am not responsible for bricked devices, dead SD cards,
    * thermonuclear war, or your 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.

    Supported Models:
    Galaxy S10 G9730, G973U, G973U1 and G973W.

    US/Canada bootloader unlock thread:
    here

    Download & Guide:
    1. Unlock your bootloader.
    2. Download S10: beyond1qlte.
    3. Reboot to download mode and flash vbmeta_disabled.tar in AP slot and reboot. Device will reboot to stock recovery mode prompting you to wipe data so wipe data and reboot to download mode again.
    4. Put the TWRP tar for your device with Odin in the AP slot and click start.
    5. Reboot to recovery via recovery key combo.
    6. Disable encryption:
    Or:
    - Go to Advanced > Terminal, type: multidisabler.​
    If vendor complain about free space left on device, will attempt to resize vendor. and it ask to - Run multidisabler again!.​
    - Type: multidisabler again. will see - Finished. when done.​
    7. Go back to Wipe > Format Data > type yes.
    8. Reboot to recovery.
    9. Flash magisk apk in twrp.
    10. Reboot to system, Enjoy.

    Note:
    To disable encryption manually:
    You need to replace fileencryption=ice with encryptable=ice only in userdata line (maybe rest lines) in vendor/etc/fstab.qcom
    To avoid stock recovery restoration manually:
    Rename system/recovery-from-boot.p to recovery-from-boot.p.bak

    Support:
    Live support is available via #twrp on Freenode with your IRC client or just click this link.

    Thank you very much @afaneh92, I followed the procedure and was able to install TWRP and magisk, and everything is working fine.
    The only thing that I'm not able to do is to re-encrypt the phone at the end. The encription procedure starts, but then it is stuck for hours on the "encrypting..." screen and nothing happens. I tried to temporarily remove magisk and also to restore the recovery partition, but nothing seems to work. Do you know if there is any workaround?
    To encrypted the the data partition again need to do factory reset from stock recovery.
