Ok so I have an iPhone 4with 5.1 installed and tethered jailbroken. Its doing the stuck in boot which should be an easy fix but it wont go into dfu mode... well i believe it is going into dfu its just not being detected by the computer. Ive had it in recovery mode and dfu and still not detected by computer I used both mac and windows and multiple usb drives and ive tried my other phone and it is detected. It doesnt matter if it needs restored or not i just want it to be detected. and yes itunes is the latest version and ive tried restin the computers and everything like that. please help and thank you.
