if u want root, just do the steps 1 and 2, and then redo the steps again without the nand erase the 2nd time on part 1, also on the step 2 the 2nd time use the csc from ur firmware... make sure u r on the correct version for root of ur Bootloader files.. v1 or v2 and now v3..

if u don't want root anymore... follow this I just did for someone... https://forum.xda-developers.com/showpost.php?p=75628989&postcount=4143 in the root thread...

most important is to use usb2 controller not the usb 3 or 3.1.. that is where I always had issues.

if at any time it stops with an error.. restart ur phone and go back into download mode again, and I restart odin...

Regular Odin for returning to stock, prince comey odin for rooting..

Also having problems returning to stock

I need serious help.

This is not my first root on a Samsung phone. I've been rooting & custom O.S.-ing since my Galaxy SIII. Up until recently, I've been very happy with my rooted/custom Note 4, but it's

This Note 8 (Unlocked~SM-N950U) is the worst phone I've had in years. I achieved root with the SamFail method (W00T!), but I've discovered that I absolutely LOATHE the Newer Samsung U/I (or "Samsung Experience", as they've labeled it) and I've bought an unlocked Google Pixel 2 XL, for the more stock-ish/AOSP feel of the OS.

My 75 year old Father, who's still using my VERY old Note 3 needs a new phone, and I want to return the Note 8 to Stock to give to him.

I've followed every guide that I can find on returning to stock, even downloaded the original firmware. Every time I try flashing the original firmware in ODIN, it fails.

Can anyone help my walk through this?

Here's a photo of the splash screen, in case it helps anyone figure out what's going on.
