are you talking about the su file? if so once it is flashed you can delete it. and the guide has a switching recoveries section that will guide you through the process, but yes you have to rename the file and put it on the sd card.
I have both the su file and the revolutionary file on the SD card, so I will delete both, thanks.
In the instructions is says to always have a nandroid backup on my computer. Question: when I make a backup (which it's doing right now) does it save it onto the SD card automatically and then I can just copy it over to my pc?
Thanks for walking me through all this! You're very kind.
