I have a JB iPhone 6 running iOS 8.1.1. I cracked the screen and want to get it replaced at apple using my applecare + before it runs out next month but the genius told me to unjailbreak it first bc the calibration system would cause it to brick. I downloaded Cydia eraser and this is what I get: Is it not possible to unjailbreak my device? Should I just go to a 3rd party place and suck it up and spend $120? --- Post Merged, Oct 23, 2016 --- Update: I found this on redit, saurik said a year ago in response to this error: "The iPhone 6 and 6+ did not ship full OTA updates for iOS 8.1.2 for some reason. I am sorry, but at this time, Impactor will not function on these devices for this version of iOS . (I might be able to support it at some point by doing on-the-fly reconstruction from the OTA from 8.1.1 via the patches to 8.1.2.)" Does anyone know if he has fixed this issue?
