I have reinstalled stock rom, re-rooted my phone using SuperSU. TWRP is now installed and working.

Update: I have flashed the v11 kernel on my phone (6.0.1 MM) using TWRP install. Did not wipe any data. Rebooted the system. Seems like nothing has changed. The PWM flicker is still there.

Update 2: I flashed the kernel again, this time i wiped the cache and dalvik cache before and after the installation of kernel zip file. Still no change. The screen still flickers even though system shows kernel already installed (see screenshot on the left - flicker bands visible). I think the combination of MM stock rom version and kernel version doesn't go together.

Update 3: Finally got it to work. I installed Nougat stock rom from sam mobile. I chose the stock rom with the exact software build that the PWM-free kernel is based on, which is Nougat 7.0 (G935FXXU1DQB7). Flashed the stock Nougat 7.0 via Odin. This combination works - Flashed TWRP 3.0.2-4, then installed no verity v5.1, then installed Updated-SuperSU 2.82 (stable), then installed v14 of the flicker free kernel, - no more PWM screen flickering (see screenshot - no more flicker bands). But somehow the phone becomes unrooted. Installed latest Magisk v13.1, the phone is now rooted, and safetynet passed. Keep getting error from Samsung's security app "unauthorised action has been detected. Restart your phone to undo any unauthorise changes". I downloaded App Disabler from Play store and disabled the SecurityAgent. No more nagging error message.

I'm thinking of going back to MM. I tried the v11 that was posted earlier but cant get it to work on MM (G935FXXS1BPLO). Does anyone have the marshmallow version of the kernel in .tar format? Or even the zip version (any MM version) is fine too.

I have been experiencing alot of headache while using my OnePlus 3T and I think it is because of the PWM flicker. I don't have much knowledge about this stuff so can someone explain to me what is a kernel ? And will this PWM flicker free kernel work on my Oneplus 3T? Because I need it badly! I'm experiencing too many headaches!
Any help will be greatly appreciated.
Thanks

A kernel is the thing that controls your device.... And no this kernel only works with the S7 Edge.
