Reflashing stock firmware?

[maxvini16]

So I have a Sprint Galaxy s6 that was rooted. I need to remove root and bring back stock firmware. Removed root with SU unroot. Im curious as to what stock firmware do i go back to. I THINK I was rooted in 6.0, so do i flash 7.0 as its the latest or 5.0 since that was the native firmware? Will flashing any version get me bricked?

Also is SamMobile still the most reliable source for stock?

As long as it's compatible firmware to your model number it should be good regardless of version.

To my knowledge the S6 stopped at 7.0, so no point even going lower?

7.0 should be good but if you want peace of mind I'd go for what was on there in the first place and then let it update ota. Just make sure you remove your Google account before flashing with Odin as I've heard stories of the reset protection messing with flashes.

So anybody have suggestions as to why odin keeps failing? Ive tried 5.0 6.0 and 7.0. All fail to flash stock. My phone is in download mode. Using odin 3.12.7. Odin does add the device correctly and i add the AP it checks it, when i click start it runs and then my phone has a weird message.

Well i fixed it. If anybody else is having this problem, try getting the download links from this YouTube video.

I tried multiple versions, different sources... Nothing. Flashed this and it worked flawlessly. Got me back to 6.1.
I take no responsibility if this doesn't work for you.
Hope it helps!
