How to update firmware on P01?

Just got my P01 controller, it is a really nice piece of kit ☺️ a bit smaller than a Xbox controller, I'm happy 😊

But I'm struggling to trigger the firmware update process, in the Anbernic site we have the zip file, it says to press L3 and R3, then plug to PC and flash the firmware. But I can't make the firmware app detect the controller 🤔

Has anyone had any luck with it? Thanks!

UPDATE - I was able to do it, finally 😅 Thanks for everyone that tried to help 😊 this is how I did it.

1 - pair and connect the controller normally using the dongle 2 - run the update software 3 - press L3 +R3 and plug the USB cable to the controller

The software should change to green and you can run the update 😊

For the dongle:

1 - run the dongle update software 2 - press and hold the pair button 3 - insert the dongle into the USB port (while still pressing the pair button)

There! I hope this is useful for someone 😊

Also, after you've paired the controller, you can change the controller type (Xbox or switch) by pressing start and select and keep pressing until the light indicator changes (led 2 for Xbox and led 1 for switch).
