Hello, I have the same problem with an Ipad Mini 2 with iOS 12.5.5 (checkra1n 0.12.4 beta). I get the error message "Exploit Failed (Error Code: -31). I changed my USB key, USB port, PC. Nothing helps. No" Safe mode "pop-up that appears and even the same error message if I check "Safe mode" in options. Anyone have any idea? Thanks in advance

I had the same issue with the iPad Air A1474 (A7) with iOS 12.5.5 and found the solution here. Try Ra1nUSB_HT to boot in to a macOS environment. I used balenaEtcher to install the dmg file in a 16GB USB drive. checkra1n 0.12.4 beta (enter 124 in Terminal) worked on the first try. I used the Intel version, there is an AMD version too.

Had this issue today on ipad mini 2. A1489. Exploit failed (Error code -31). I tried enabling the experimental / untested versions with and without, same error.

When it says Right before trigger (this is the real bug setup) wait 2-5 seconds and then unplug and replug, said DFUSyncUpload FAILED: -1 then finished and the checkra1n showed up on my home screen a couple of minutes after power on!

Same here on v0.12.4-beta (running on a Mac) for the iPad Air 1

EDIT

This is apparantly an UI bug. Works fine in the terminal!
