Hi everyone! First at all: sorry for my bad english. I have an iPhone 5, and I decided to update it to iOS 7 BETA 3. Everything was going fine, when i plug it the lightning cable, an error shows every time, saying that was a 3rd party cable etc etc. I souposse all you know this error. But suddenly, it stopped charging. When I plug it in my computer, doesnt recognize my iPhone (not iTunes, Windows!). I cant even downgrade to iOS 6.1.4... I tried DFU mode and nothing happens when I plug it in. Only an error shows up: "Windows cant recognize this USB device", or something like that. The only way i have to charge it is shutting down the iphone plugged in. While it is shutted down is charging... I dont wanna buy an official cable, but i guess i'll have to. Anyone has a solution? Thanks for your attention.
