I have a huge problem. For an exhibition of international impact I have to mirror an Ipad 3rd generation to a 24" screen (16:10). The only possible way seems to be a jailbreak and DisplayOut. The problem is the Ipad is running 6.1.3 and I can not up-or downgrade the Ios version since it seems Apple is ONLY signing 7.1. Has anyone got suggestions to get around this? I have tried the manual restore with the according ispw file without success. I really need to get this to work within a week - else having to use a Nexus 10 tablet or similar.
