i succeded flashing gsi rom, it's working great.
don't flash magisk in twrp or patch boot.img with magisk because booting gsi rom failed, only with the stock boot.img that's working.

edit: i can use supersuser PHH but is there a way to make magisk working on gsi ? i wish to pass safetynet attestation

Hi! First of all, great work!
I want to confirm that what happened to Jnewell05 happened to #metoo :ROFLMAO: . I have a Samsung S21 5G Snapdragon - SM-G9910 running latest OTA update from March - G9910ZHU1AUB7- and BRI - CSC (if that counts). Like in our coleague case, flashing stock rom, reboots just fine.

LE: for a verry brief moment, just before the moment that recovery should "kick in", a yellow message appears in a flash and is says something about "Security BIT" - couldn`t read entirely because it appears and dissapears, as I sayd: in a flash. I hope this helps the cause.

LE2: The message about I was talking is: Set Warranty Bit : Vmeta. After that, just the red message and yellow exclamation mark and bootloop

Can you or anyone confirm this works on already magisk rooted G9910?

I just finished setting up the phone and temporarily lost root when i renamed the Magisk app, had to reflash the patched IMG with HOME_CSC and thank god i didnt lose settings

My whole reason for TWRP is the backup/restore functions, so i never have to suffer this kind of heart attack again

I'm on OneUI 4.1, May release. Anyone?

    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 S21 G9910, G991U, G991U1 and G991W.
