I had an iPod shuffle that was like that, no computer would ever list it in the iTunes window. Turns out, it somehow reverted to "Mac based" software(it was old) during a reset/restore and only a Mac would recognize it. Do you have anybody with a Mac around? Once we got it recognized, we could upgrade it's software and then my computer could see it again.
It was weird, but it fixed it. I wasn't/am not aware that they do PC/Mac specific stuff anymore.
was this problem solved? I have exactly the same problem with my ipad1.
I was not able to solve the problem. I ended up taking the iPad down to the Apple Store and they looked it over and said it was not fixable and offered a refurbished iPad for $299. I did not take them up on the offer.
I had the same problem with my Ipad. Plug it in to itunes and it wouldnt see it. Just see the ipad. Then it would make a noise and disconnect. As far as everything else it would be listed as N/A (In itunes) Tried everything. Changing cords, Computers, Updating, another cord, even told my ipad I would take it out for ice cream. Anyways, The charging port was bad. (Daughter Board) Replaced myself at $49.99 at badda bing. Back in action.
I even tried to restore it to factory. It would take 45 minuntes then throw the 1602 error. The new port did the trick. No error either.
My question now is, is it worth spending the money to replace that port on a 1st generation iPad? Can that iPad take the newer iOS 6 or is that iPad too obsolete? Any thoughts?
