I am pretty new to the android OS. But i love it, the downfall is how long it is taking for 2.1 to be released. So I decided to root and everything was going well until I tried to make a nandroid backup. I followed a step-by-step guide, but instead of my phone booting into the screen with the android logo it goes to the /!\ screen. That is really the best way I could describe it. Sorry and thanks in advance.
