Hi
Yesterday, I did the update of the new iOS 11 for the my iPhone 7 Plus, everything was going well, until the update did not come to an end, I was doing via OTA.
It appeared on the iPhone screen the message to connect the device to iTunes via the USB cable. So I did, in iTunes appeared the message, UPDATE OR RESTORE, I loaded update and ready, since then I have the iPhone lifeless. The error that appeared was ERROR 56. I did everything I was told, I changed the USB cable, computer (two iMac I have in the house) and now I'm trying on a Windows PC.
I need your help. I can not even downgrade.
I look forward to your help.
I was using the od iOS 10.3.3 Beta 4 version and I was going to install the iOS 11 BETA Public version
thank you so much
