I loaded up one of my old 10g nandroid backups and fully unrooted.Kuma beat me to it ^^^^ This does not work on ICS roms for L9. It goes thru the motions but the su app is not found afterward. I have uploaded a copy of the ICS P769 spritebud. https://www.dropbox.com/s/zhnkrlpu4u6k744/spritebudICSp769.zip
Thanks
No su app is installed during use, just the supersu binary
