Can you redownload the IPSW from ipsw.me and try again? The IPSW you have now might have got corrupted at some point

Just keep rebooting into DFU mode and run it again. This just means the exploit failed.

MatthewPierson commented 4 years ago

Thats the same error, just keep trying. Nothing I can do about the low success rate sorry

pongsupavit commented 4 years ago

Normally, how many times should I try, or Is there any other solution to make higher success rate?

MatthewPierson commented 4 years ago

I will be closing this issue in 24 hours if you no longer need help/the issue has been resolved. If you still need help then comment with what you need and I will not close it.
