Hello, I have an iPhone 5 which was on iOS 10.0.3 yesterday. It was reset and everything worked as it should. Today I took it to myself and connected it under iTunes to install iOS 10.3.3. Unfortunately, a mistake appeared several times. This iPhone can not be restored. Error (-1). After several installations, one time I managed to install iOS 10.3.4 (I clicked to download and install myself, .ipa-file 10.3.3 I had with ipsw.me) but the phone did not detect the sim card (all the time the message Search was displayed ). Additionally, after connecting to the WiFi, he did not want to activate (dialog window with the fact that the iPhone activates for 5-10 minutes, it disappeared with the message that servers are unavailable and can not be activated. I thought that since iOS installed, it is 10.3. 3 will also be installed, however I was wrong and returned to the starting point.
This is not a software issue It is a hardware problem baseband CPU
