Development [RECOVERY][UNOFFICIAL] TWRP for Galaxy S21 Ultra (Exynos)

[afaneh92]

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.

 * 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.

Any custom rims for this device yet? Maybe a Pixel Experience ROM?

 

[FreeRunner2017]

Any news on rom development by chance?, Just curious thanks.

 

[xAD3r1ty]

It will take a big while before custom ROMs, don't expect them too soon

Hello everyone, I only have one question, besides the Twrp and the vbmeta_disabled_R.tar do you also need to flash a Multidisabler via Odin? Thank you.

You just need to go to advanced then open terminal in TWRP, and type multidisabler, then wait, then type it again.

I wish there was a very easy way to patch AP to keep TWRP after a dirty flash manual upgrade.

1.Easiest option - Go with custom ROM (If available)
2.Second easy, modify AP and patch it.
Extract all the contents of AP file - delete recoevry and vbmeta images - Repack as tar (You can use 7zip or similar) - Patch it with magisk
After flashing, straightway go to TWRP - and apply multidisabler before booting device.

This would clear the User data / Accounts also, yeah ?


@afaneh92 _ Bro, I think the existing TWRP doesnt mount Data on the Newest March Security Patch.
I had no issues with the February Firmware.
Could you have a look ?

You asked for dirty flash trick right? If erasing data and acc then it's not dirty flash.
I don't have any issue on March secure patch

What could be causing this issue?
Did a full stock flash as well, and repeated the TWRP process.

Run multidisabler script in twrp terminal
