How to restore player rigs to the original factory settings

I have somehow caused two different rigs to sound the same and I know they were not that similar. Since all Ive done with it is change the order of a few of them I happy to just wipe the player and install the factory 50 that came with it.

I don't recall the Stage or Heads ever being so weird but perhaps my
Player is haunted!

Is there some button press combo to do it or do I need to reinstall firmware?

 Factory reset
This will overwrite all user data and settings and recover the as-delivered-state: Please hold the four buttons BANK,
TAP, Bluetooth®/Wi-Fi, plus KONE while powering on.

I’ve tried this twice with no luck.

There are 4 small leds to the left of that row of leds that light up blinking red and the far right round button is lit in white. It stays that way indefinitely as I gave up waiting each time. How long should the process take?

Edit to add: I got it to work, I think I was pressing one of the wrong buttons the first few times I tried it. When in doubt use more coffee...
