Hello, This is my first time time installing a custom ROM. I'm excited about all the stuff I've read about ShadowROM but I'm a bit concerned at this stage of the game. I've been staring at "First Boot" install screen for about 20 minutes now.. I'm not sure if/when I should start being concerned. I read on the forums that first boot process goes through your SDCard as well as your phone hard drive. I've got a few gigs on the SD Card so I just want to check if that's the reason. I've never installed a custom rom before so I don't know how I should procede and if/when I should possibly consider aboirting the install and any negative effects that may have. I did do a nandroid backup of my phone prior to this. Thanks in advance and sorry if the information is present elsewhere, I couldn't find it.
