    Need a workaround to downgrade back to Android 9 of lower bootloader Ver.

    Hello,
    I desperately want to downgrade my M30s (SM-M307FN) back to android 9.
    It seems that i have no chances with the official firmware because my current bootloader is now ver 3 and there is no ver 3 android 9 firmware.
    My current Software is :
    PDA = M307FNXXU2BTD1
    CSC = M307FNOJM2BTG1

    What are my available options?
    If I unlocked my bootloader and installed TWRP, would that allow me to use the official android 9 firmware and downgrade?
    IF not?
    Is there Any know stable Custom Roms that would bring me Android 9 and known to work smoothly on M30s?

    I have no experience with custom ROMs, so I need directed ROMs recommendations if possible.
    Please

    Hi there

    It's not possible to downgrade your device to Android 9 due to security...

    Maybe a Samsung Service Point can help you.

    We don't support TWRP & Custom ROM's; when using those, you'll lose the secure functions of your phone...

    Thank you for your reply,
    I don't think that a service point will do such a request.
    But thank you again for you advice
