I went through all sorts of trouble following suggestions on this forum and nothing worked for me.
Here is what did work!
I was searching how to do factory resets for POD HD PRO and a different forum had instructions for how to boot up into Flash mode.
I held down the down arrow on the ENTER/MOVE control arrows to the right of the LED while powering up.
It put the unit in Flash mode. Then I went into Line 6 Monkey and it properly displayed my firmware and allowed me to update my firmware.
Hope this works for others!
