hi, my 3rd generation iPod that i jailbroken a few hours ago with blackRa1n shut down unexpectedly & now it doesnt turn on, it just gives me a black screen with iTunes icon & an usb cable, when i connect it to the pc it says is on recovery mode, i unplug it & the same screen stays. i've tried to restore it but somehow it gives me an error when it finally downloads. the last app i used was Cydia installin backgrounder(the one you can put apps running on the background). It has the 3.1.2 firmware, i bought it for christmas so i have a month with it, its the latest version on store. It has 8GB on storage. what can i do? please help me!!!!
