How to Fix Xhorse Dolphin XP005 Error 56 57?

Question:

Error 56 57 popped up on Dolphin XP005‘s screen once I got it. I don’t even use it and the bracket is there, then the error just showed up. How to fix this?

Answer:

XP005 Machine will conduct self-test when you turn it on for the first time.

The axis inside won’t move due to the bracket that has not been removed.

The errors will display if self-test fails.
