Root backup factory image/settings?

[pauly814]

Is there a way for me to create a backup of the factory image of this phone so that if I mess anything up during rooting, etc. I could go back to factory settings? Is there info on how to do this?

Thanks

There is not a way to make a backup, but there is a file that will put youre firmware and bootloader back to an unrooted, out of the box state.

Rest assured, there is a way back if you screw it up.
