triangle warning and no starts
I sometimes failed the connection to the SIM, and decided to restore, now I see a warning triangle next to no service, and if I put the sim, it is as if I did nothing, I checked the connections of the motherboard to the connector sim and they are fine. When I try to activate the phone, after putting the wifi, it appears "could not activate." To activate iphone it is necessary to install an update, more information on support.apple.com, turn off "I installed the latest version and nothing
Is dit een goede vraag?
