SP360 4K Need updating help PIXPRO AZ421

[teamzr1]

Hi, sorry, I cannot find on this forum a section for my PIXPRO AZ421
But maybe you can help
My PIXPRO AZ421 firmware is V2. I downloaded a new V4 firmware bin file and coped it to the SD card plugged into the camera
In setup, I select firmware, and it shows V2 but has nothing there to start the process of updating to V4

What is the problem ?
Where else could I have put the V4 bin file, does the SD card need a different subdirectory made, and bin file put there ?
What am I missing when in setup, firmware, to see a function for update process ?

Thanks for any help . . . JR
