Can someone help me get my device to re-activate? I have an iPhone 6s jailbroken on 9.3.3 and after a reboot on Friday the 13th it suddenly prompted me to activate the device again. It already had the language and region settings and my WiFi info. All my settings and info are still there, it just won't let me past the iPhone setup. When attempting to activate via phone or iTunes I get an error that the OS needs to be updated in order to activate. please help me get back into my phone. Updating this device isn't an option. I went out and spent the $1100 on a new phone so that I could keep this one where it was.
