Purchase iOS System Recovery, thinking it could help me, as I could not get recover from iTunes. Tuneskit behaved same way. I wasted my money. It says can repair up to 50 kinds of iOS system issues on iPhone/iPad/iPod touch. But in fact, any problem you mark result the same process, reinstalling the firmware. And it can't install unsigned ones. Purchased the 1-Month License, with auto renewal. I want to cancel, but cannot find where... If you do not want to lose money and time, do not buy it.
