You flahed the stock ROM & bootloader along with it
Or just flahsed boot loader and modem ?
& are there any problems on this bootloader due to which you want to return back to kk?
Is it as simple as grabbing that latest firmware on Sammobile and flashing it through odin? Because i want to be running everything up to date.!

why is urgent ? I do not understand?
Every time I try to flash the combination file for 950U, it fails immediately and throws the "SW REV CHECK FAIL" error.
I'm on latest BQL1 and trying to swap CSC using the method posted here before.
Any suggestions?

I've used comsy and it still fails..
When you mention u1 are you referring to the unlocked firm or the baseband.
Edit: U1 is the only combo I can find for 950U.
I'm trying to change VZW to TMB.

Hi, I want to downgrade back to Android 6.0.1 Marshmallow by flashing it through Odin. But when it starts flashing, the box says FAIL. Any solution to fix this? Thank you in advance.

Before flashing the firmware you need to flash the marshmallow bootloader and modem for your device then you can successfully flash firmware.

AP I mean sorry. Look at all the boxes you ticked to flash on the right hand side. Only AP should be selected

I tried, and it downgraded to Marshmallow. But it doesn't downgrade the bootloader.
I have an Sprint Samsung S8. I want to update to Android Pie 9. Its currently on Android 8.0.0 - R16NW.G950USQU5CSA4. And I want to flash with Odin to any compatible Android Pie FW. I am personally not looking to unlock or anything. The confusing part is that when I research the FW version (G950USQU5CSA4) it comes as a Verizon FW. So I am not sure if is safe to flash any of the Pie FW available on sammobile for Sprint.
It is safe to flash for example to one like G950USQU5DSD3 that appears in Sammobile and is for Sprint?

For any newbie like me who ever had a look at this thread. This definitely work as said by @kpwnApps, I downloaded SM-G950U, build G950USQU5DSD3 (3.92GB) from Sammobile and flashed with Odin. Flashed AP, BL, CP, CSC (not CSC_HOME) on its respective place on Odin. 5m 32s later it was updated with no trouble.

Last question, I am personally not interested. Just curious. As long as is the same android version, would it be possible to downgrade too by flashing with Odin and earlier version? or would something like that cause a brick?
