my motorola droid is rooted and i'm using the sapphire rom. i want to do a nandroid backup but it won't let me boot to recovery. i'm holding down the x button while powering up and it just shows the M icon. after awhile when i'm sure its not going to do anything else, i give up and let go of x and my phone boots up back to normal. is there something wrong? how can i fix this?
