I want to make a small contribution to the thread in question, I have a gw4 ldu which did not allow any device configuration. I downloaded the SM-R890 EVA8 file and unzipped it with 7zip and then retransformed in tar format again with 7zip. I then connected the gw4 with netodin and uploaded the file to the device. Finished the job everything works wonders, it also received the latest update released by samsung. Tanks to Adfree for his hard job

The bootloader revision is the 5th character from the right - 1FVC8

The 4th character from the right indicates roughly "UI version" - it updates every time that Android and/or One UI updates.

So as long as bootloader revision remains 1, it should be possible to downgrade to any previous firmware. Once that 1 changes to a 2, that's when downgrading will no longer be possible
