I'm having trouble downgrading my six + from 8.1.3 to 8.1.2 so I can jailbreak it. I have the correct ipsw file downloaded onto my Macbook but I keep getting the error prompt that the firmware isn't compatible with my device. I'm just looking for some help before apple stops signing 8.1.2. I appreciate the help
