Unable to extract component: iBSS

[mec1]

I'm new to this and don't know if I didn't set something up right or what I'm trying to do is just not possible. I"m trying to go from 9.0.2 (13A452) to 8.4.1 (12H321). After I attempt this, it errors out at extracting iBBS and locks the phone in recovery mode. The only way out of recovery mode is by using FonePaw to get out. I need some advice. --Thanks to anyone who can help me out--

Your libzip is probably too old (not compatible with files >= 2GB) or improperly built on windows. Apart from that please be aware that you can't downgrade the firmware anyway (unless it's one of the old devices like iPhone 4 that have a bootrom exploit).

Hey bro. Do you use the OS X EI Capitan to do this? I faced this problem and switch to a Yoesmite machine and make it.
