Hi welcome to AC!
Did you get from sammobile the firmware ?
And what region is the device orginaly from BTU?

yep from sammobile, Indonesian, but the latest default edition firmware yet not available in sammobile so i search the other and were downloading now, so i need the answer about "can i flash it again with the same version but different edition i mean the default edition?", cause why should i waste downloading things
You can , Odin will say pass it fail if compatible or not so that's pretty straightforward with Odin and stock firmware, but you might have region compatibility issue not getting signal

Hey, i found out that my phone accelerometer is not working, actually my phone is BTS Version but now it is installed on newest default S20+ version of android.
I want to try it out to turn it back to BTS version firmware again, so i will know that my accelerometer caused by the firmware or not.
But the latest BTS version firmware is one step lower than the Default one, how can i Downgrade my phone to install the BTS Firmware?
Mostly what i know they said "You Can't" But am hoping the opposite.
Btw my Phone build is SM-G985F, Running XID(Indonesian) CSC! Maybe you know there is BTS Version in other country CSC that get updated already?
If it not possible than will there a new update i can wait for BTS Version? Cause samsung been 2 months not updating the BTS Version!
You would have to search around xda or sammobile website for build number lower and see if it will flash

Give me an example of build number, cause there is only PDA, CSC.
Hmm btw is the BTS Machine and Default different? Why am facing this issue.
For information, my original machine is damaged by water, and i bought a machine unofficially and **** it is BTS Version.
Go to settings>about phone>software info and see what your current build number is more importantly the last 4 and u can try a firmware one below it , ill provide screen example of mine Screenshot_20210722-104955_Settings.jpg

Mine is Due4 and willing to flash it to due1, but it said sw rev. check (Bootloader).
It means the bootloader preventing to downgrada a firmware!
Is there a way i can bypass it?
Then it wont allow you to downgrade , can try prince comsey odin , if doesn't work then im not aware of a way to do so and most likely not .
