Thanks! I will try it when I finish downloading the File from SamMobile.
Just to Clarify:
I need to remove the .md5 from the name? So just .tar? and then extract and put the boot.img on my sd and install flashify and flash from there? And my kernel will be back to stock?
If I wanted to unroot, would i just flash the .tar file through Odin? That would remove TWRP, root and custom kernel, am i correct?
