Apple phone is not functioning properly
I used an application on my Apple phone to remove all limitations using a free iOS jailbreaking tool. After I while I set-up another customizing application where I had to update the phone; this was a normal process for me because I have already done this process smoothly many times in the past, suddenly my phone will not log in- it will just show the phone logo and not push to the main screen.
I even tried putting the device on device firmware upgrade mode but it did not work. I cannot even restore the phone because my pc cannot establish connection between my pc and phone. I have attempted to fix this by using so many programs already but nothing worked. This has become a really big problem for me. Can you please help me by giving me advice on what to do to solve this issue? Thank you.
