I just tried the instructions and they worked perfectly for me.i finally have root again.THANK YOU!!!!!!
adb kill-server > nul
adb start-server > nul
ping 22.214.171.124 -n 1 -w 500 > nul
adb wait-for-device devices > nul
adb shell "/system/su-backup -c 'mount -o rw,remount -t ext4 /dev/block/system /system'"
adb shell "/system/su-backup -c 'cp /system/su-backup /system/bin/su'"
adb shell "/system/su-backup -c 'chmod 6755 /system/bin/su'"
I then tested to see if I have su rights by going into adb shell and running "su":
If you do not get any errors and just the shell prompt then that should mean that you have su rights. Then I did the following:
su -c 'cp /sdcard/su /system/xbin/su'
su -c 'cp /sdcard/Superuser.apk /system/app/Superuser.apk'
su -c 'chmod 6755 /system/xbin/su'
su -c 'chmod 644 /system/app/Superuser.apk' <----- I didn't do this but probably should
su -c 'rm /system/bin/su' <----- I didn't do this but probably should - some with more knowledge please let me know why this should be done - thx!
Or you can do it in the Windows Command line (dos prompt):
adb shell "su -c 'cp /sdcard/su /system/xbin/su'"
adb shell "su -c 'cp /sdcard/Superuser.apk /system/app/Superuser.apk'"
adb shell "su -c 'chmod 6755 /system/xbin/su'"
adb shell "su -c 'chmod 644 /system/app/Superuser.apk'"
adb shell "su -c 'rm /system/bin/su'"
After rebooting I ran my voodoo OTA and it asked for superuser rights and in voodoo it says that I have root and root privileges.
Hope this helps!!!
EDIT: Forgot to add that I copied the files su and Superuser.apk using ES Explorer to the root of my internal sdcard. Oh, and "Thanks" Matt!!!

If you guys are having issue restoring root, you should use this tool made by Mattlgroff:
su if you don't get the # sign here it will not work.
adb push su /sdcard/
adb push superuser.apk /sdcard/
cp /sdcard/su /system/bin/
cp /sdcard/superuser.apk /system/app/
then rebooted, ran voodoo and it asked for su permissions.then ran root check to make sure and all was good.
I'm not sure if this will work for anyone else.That's just what I did,but all apps that need root permissions are working and android tether is working.
