Yay I finally fixed everything! This ROM is so snappy and amazing. I used termux to get 1080p for better battery life I get about the same battery I get with NobleROM 1.5 maybe a bit less. But i like it more since it's stock and no Samsung bloat.
can you please guide me to change the resolution using termux?

    @garett_09 for the new build

    Cheers mate. Running WhiteWolf now and it's immediately more responsive. Very noticeable difference. Hopefully it doesn't impact battery life too much. Noticed the different scheduler (schedutilX).
    well I can confirm flashing WW kernel does make the rom more responsive despite in my usage with the compromise of battery life
    By "Stock Vendor" do you mean stock rom?
    So do I have to go back to stock rom first and then flash your rom?

    simple question is yes, the easy way is you could download any custom rom like DevBase or Alexis ROM and take the vendor image from there and flash it on TWRP before flashing this ROM
    with stock rom you mean for example devbase from alexndr (android 10?)
    and is a specific version of twrp recommended?
    You can try, the flash requires Stock Samsung Oneui 2 - 2.5 (Android 10) Firmware in this case. (Bootloader + Vendor).
    Rom like the one from Alex flashes our system / vendor partitions.

    Anyway i think, if someone suggests Vendor Stock Rom it means you need restore the original software from your local mobile network.

    Today I was installing dotOS on my S9 UK variant, and what i noticed a very nice stable system.

    SamFirm_Reborn to download Original Rom
    Twrp 3.3.1-1 S9 starlte

    Quickly and easily flashed stock rom, then TWRP and dotOS v5.x.
    I personally suggest these types of options.
    It's safe and good to renew the original software on your phone from time to time, a kind of refreshment :)
    Good luck buddy!

    Repare o link de download : D

    Já usei isso antes, é incrível ...

    Mas agora eu perdi o .zip e não posso baixá-lo novamente :(

    wow this ROM is sleek smooth, the UI is different than any other AOSP based ROM, and it brings some Android 12 touch too. Overall working good without any issue on my S9+. I hope this ROM have a long life for this device. Thanks Dev
