Hi im new to this site. but i recently installed rockbox on my 30 gig 5.5gen ipod. after trying it i wanted to go to back to the factory setting. But like a dumbass thinking if i only delete the rockbox folder that it will set it back to the normal setting. Now my ipod just stays on the Apple screen. And im not able to set in disk mode. only able to restart it. i wondering is there anyway to fix this?

Or do i have to just try and send it back to apple to fix it?? Thanks for your Help
