The above machine is rooted. I have been trying to make a nandroid back up. When I try to get into recovery, using vol up, home and power, machine stalls on the first screen. I have quick reboot installed and when I try to go into recovery from there I get the same result. I am unable to use the power button at this stage. To get the machine running again I have to use the download mode, home,vol down and power, then choose vol down to restart. At times this is not enough and I have to use Odin and a cf_autoroot tar to get back to a working machine. I would say that my difficulty is a result of something I have done, the machine works well other than this issue. What I eventually want to do is flash some roms and I don't want to go forward till I have the nandroid back up. Any help resolving this issue most appreciated.
