My lil bro has an iPod Touch 2G (old school now) with iOS4.x.x JailBroken with Multitasking/Wallpaper Mods. The battery died. I plug it in to charge it and it goes from the boot screen to the battery/charging screen (NOT THE LOCK SCREEN) and then back to the boot screen. Then sometimes it goes to the Rotary Apple Screen and then it starts ALLLL over again. Any help?
