How to upgrade jailbroken iphone 6+ to 8.1.1
You will lose your jailbreak, but just go through iTunes.
Last time I upgraded a jailbroken iPhone, I had to force it into DFU mode because regular iTunes restores kept failing.
I'd also avoid restoring any backup data created while you were jailbroken.
DFU restore to 8.1.1 and then re jailbreak
