I already take part in Apple beta software program on ios 9, so my ipad mini 3 upgrade to 9.3.3 beta 1. Then I eraser profile of ios 9 and install profile of ios 10 but I cannot install, it put me into recovery mode. So I go to ios 9.3.2 final and try again but it still not work. I try to put my device to DFU mode and install firmware from ipsw file, my itunes has error code 14. Now my ipad must go to 9.3.2 to use. So confusing with my ipad. Someone can help me.
