i just received an ipad 1 that won't turn on. it was jailbroken, and tethered i believe. i don't have any background information on the ipad at all, other than it shows a potleaf during bootup. i'm not sure if that's indicative of a tethered jb solution, or just a custom boot logo that was added by the owner. when powered on, it shows the apple logo for a bit, then does the pot leaf animation, then the little spinny circle appears, spins about once or twice, then it freezes. the ipad won't charge; as soon as it collects it's minimal charge, it attempts to turn on, crashes out, and repeats until complete exhaustion of the battery. it begins charging, and the process repeats indefinitely. i can enter recovery mode sometimes, but the device isn't recognized via usb on anything. i've tried three cables, three win7 pcs, and a macbook. i've extensively (in the last 24hrs since receiving the ipad) researched the matter on google and this forum alike, but can't seem to make sense of it. many folks suggest using this tool, or that tool. but i can't, because no pc will recognize the device to allow any tool to operate on it. i'm not entirely sure if i'm entering DFU mode properly or just regular recovery mode, because i cannot get the device to power off in order to commence the DFU sequence. i've had every iphone, and jailbroken all of them, but i've never done a tethered jb, so my expertise in this exact context is seemingly lacking. do i sound correct in assuming that this ipad IS in fact on a tethered jailbreak? if that's the case, how can i get out of this cycle? i'm unable to get any information from the ipad such as os version, etc. any help is greatly appreciated, but please note the following: i've tried resetting the ipad, the pc, and reinstalling itunes. i've tried a multitude of cables (all original apple, as several iOS devices exist in my home). i've tried iReb, fixrecovery-win, and a handful of other tools (all cannot connect to device). i've inspected the dock plug with a magnifying glass, and all looks as it should. thanks! EDIT: i'm trying to get this ipad serviceable for my wife, so it needn't be jailbroken, but it's ok if it is. as long as it turns on and does facebook lol.
