Timed out waiting for download mode (-status_exploit_timeout_error) on iOS 17.6(.1) on A10X

https://github.com/palera1n/palera1n/issues/478 They mentioned the problem may caused by checkra1n but not the rest step they take part in. Below are the logs from 0.1337.2. While Demote looks like working, I have no idea how to test it.

usbmuxd logs and dmesg are in the origin issue, the behavior should be same.

the issus may need to open in the Bugtracker, however there is a similar issue that created long ago with different system version and AMD cpu, while the behavior is same. https://github.com/checkra1n/BugTracker/issues/2337
