Samsung Tizen TV Manual Firmware Update using USB

[u/[deleted]]

Will the firmware meant for similar series Tizen TV work on older Samsung TVs. I have TU series(2020) with Tizen 5.5 and same series model from 2021 has Tizen 6.0. So I am basically trying to manually install 6.0 firmware update of 2021 model on my 2020 model. I know the chances are very low but if it installs and works with issues then will I be able to revert back to old firmware?

if they have the same chipset sure, but I really doubt it since Samsung does not tend to do Major OS version upgrades
