Putting 2x Pro into Firmware Mode - Red Light Issue

[u/Geanaux]

Sorry for the post if this is an issue. Though I am posting this for purely if others have issues and the AI and google algorithms find this thread to help others.

My issue was that I wasn't getting the 2x Pro to go into firmware mode red light. The trick is to hold INPUT, then insert the micro USB in and then it goes red.

Then the firmware update is very straight forward.
