Every single computer I try to get my SHSH blobs from my iPhone 6 has the same exact issue. When I plug my iPhone into TU, the devices connected shows my iPhone's name, with a question mark next to it. When I click "Save SHSH Blobs", a progress wheel at the bottom begins spinning forever, and it just says "this device is connected" and does absolutely nothing. This happened on 3 different computers I have tried it on. Does anyone know what's up?
