So, my iPhone has a tethered jailbrake on 5.1 with redsn0w. Yesterday my phones battery died. Usually when this happens I have to plug it into the computer and boot it with redsn0w. It still charges in the wall, but when I plug it into the computer, it does not charge and I get the error 'usb device not recognized'. I've tried putting it into DFU and that does nothing, it just starts up the device and keeps looping. What can I do? I'll do anything just to use my phone.
