I use an iPhone 7, and whenever I try to jailbreak, the progress bar starts alternating between “checking if device is ready” and “right before trigger”, and then after a few minutes, the screen prompts, “Exploit Failed (Error code: -21)”. I have switched the USB ports on both the USB flash drive and the iPhone, and I have tried using USB safe mode, Graphics Safe mode, and RAM mode. I even tried the same thing logging on as both anon and root. There is nothing else I can think of, since a day ago, the jailbreak worked just fine.
