So the same as without holding the power
If you have a jig you might still be able to get into Factory Service Mode. It does still give the same error beeps even when using a jig.
I had this issue and was able to use FSM to go back to Rogero 3.4 then back to 3.55 Kmeaw.
Look up and follow one of the downgrading guides for detailed instructions.
