Help please. I have to take my phone in for a warranty issue and I need to re install my original backup off my SD card. When I use Flash CWM recovery I get a message saying error superuser denied. If I try to do it with Reboot into Recovery I get the same. I have done a restart on my phone to see if it would help and I get the same. I have flashed recovery several times before with no issue, so I know it has worked well before. Any ideas.
