Rooted & flashed I997UCKI4_UC_ATT. Now not rooted.

[Mr.Gadget]

I used SuperOneClick 2.1 to root and then flashed I997UCKI4_UC_ATT using Odin-1.7
Phone works OK. It has a weird multicolor screen on initial boot and every two boots it will start without an Internet connection.
I am swapping this phone for an SG2 next week so I'd like to get back to stock. Probably no big if I can't but I don't like the multicolored screen on boot.
Thanks!

Those are all known issues with that build.

You can always flash back to stock using Odin.

I tried that but it fails. Maybe I am doing something wrong, but, if my device is not rooted can I use Odin to flash back to stock? If I can, then that means I am doing something wrong and I'll just retrace my steps.
