The only logical way I can think of fixing this problem would be manually editing futurerestore in Xcode, editing TSSR's command set manually, recompiling it, and running it with a custom option for my device, being N71AP. I had no luck navigating Xcode and have no idea how you got libraries like libzip for dependencies in macOS.

I am running macOS High Sierra with the 2009 27" iMac and a 32GB iOS 11.3 beta 6 with set nonce-generator using noncereboot's empty_list.

I am currently trying to get an Ubuntu installation running on my iMac to run futurerestore in linux, as the Windows fork cannot detect my iPhone 6S in recovery mode, yet does just fine and gets past the above point in Normal mode.

I ran the tool in while my iPhone was in DFU and in Normal mode, first with 10.3.3 installed then 11.3 beta 6 installed. Neither worked.

did you ever succeed? This problem still comes up when using "--latest-" for me.
