Ok, so If I go through the motions like the old ways with added things, will it work?
1. Put update on external SD card.
2. Create Voodoo / SU root file
3. Temp unroot
4. Install update from SD card.
5. crank up SU and Voodoo and restore back up.
Sound right?
So long as you go into your superuser app and check for updated su binary first, yes.
