PS : Who can handle consequences of dirty flashing, they never need to ask this question in forum. If you dirty install then handle it yourself .

Can this be flashed in twrp? Does it have any performance enhancements over stock? These two things are what will make me flash this in a heartbeat.

If it had a kernel that was built with Clang 12, or Proton Clang 12, my goodness - that would be the icing on the cake. in my opinion, the stock kernel is just not that good.

Wow, that was fast! Currently running a OnePlus 8 Pro and this is why I'm switching back to Samsung. The OP devs haven't dropped anything new in several months. Awaiting my AT&T S21 Ultra 512. Fingers crossed on a root method for the Snapdragon! Cheers

Have you seen the Galaxy s20 or note 20 forums? It's like Dr Keton ROM and nothing else. If development's the reason you came to Galaxy S21 you're going to be very disappointed.

8 Pro development is/will going to blow this out of water. Just saying..

Doctor, I've missed yah. I'm so glad you planned on making ROMs for S21. I thought your work is exclusive only for the Note series.

Yes, this is exceptional. I do make rom for N20 series only. But some friends and loyal users insisted and couldn't resist.

Thank you doc, I will love my G998B more. I loved your ROM on my Note10+. I planned on buying the N20U but ended up getting S21, I regret a little because there were no Dr.Ketan ROM. But not any more. Thanks so much.

Bro there are so many users who bought note series(exynos) only because of you. Because your custom roms are awesome with zero bug. Now, you started making rom for S21 series, many people will head over to newer s series including me. Thank you so much for awesome work.

@dr.ketan , I noticed an annoying bug with the rom. Viper for Android simply will not install/process. It installs fine on stock one UI 3.1. Could you kindly take a look at this. Viper is hands down the best sound mod for Android that exists.

Can you tell me the exact steps you did to get this to work? What exact versions of viper?

Also I already followed your instructions on 'step two' for tweaks pro. I followed the instructions exactly and did not receive the Tweaks pro app that I paid for. Please send me the APK that I paid $25 for.

EDIT: Dr Keton came through and sent me the tweaks pro app. Very happy now.

Hello Doc, I'm about to install TWRP. I just have a few questions.
-Secure Folder is still a thing like on N10+, no?
-And the dual messenger is still bugged like the previous?
-Combo key required or no? Thank you.

    If no major bug found then it will be public tomorrow.

    It's 5 min job to create twrp flashable zip for bootloader and modem, but it always carry high risk of bricking device. If bootloader file is corrupted, and suppose you flash using twrp, your device will hard brick and only way is to replace mobo
    That's the reason, I never provide twrp flashable bootloader. My bootloader files always comes in md5, so in case you have corrupt Download, odin will failed to flash to protect your device.
    So, in sort never expect twrp flashable bootloader by me.

    How?
    Doesn't work for me. I'm on latest R07, using LSposed Magisk module and that seems to have broken the SafetyNet.
    I have tested LSposed yday for other purpose and safetynet passing with it too. Also GooglePay working fine here too.
    Regarding your old query about, dual message screen bootloop is newly implemented security since A11. As of now only Pro version have experimental fix.
