It’s unusual that the middle side button (the Wi-Fi change button) does not cause the blue LED or the Green LED to flash. This could be a hardware problem, possibly with the button itself. Can you contact the seller and ask them if there were any known problems with the Wi-Fi?
If you sign up for the partner program (free to join), you can put the camera into developer mode, then use Vysor and a USB cable to apply a factory reset.
Depending on your technical knowledge and motivation, it may be too much of a hassle. However, it may be a path forward. backup all your images to your computer before you apply a factory reset.
I have some understanding of android and linux! we’ll see
I got it from cex here in the uk - but they only have another 1 and its miles away!
I have registered for the developer partner program so i can adb into it and see whats going on…
I have looked at a tear down video of a unit that got waterdamaged and can see they are connected via a ribbon cable that could have failed or the button itself - but dont want to strip it down to find its really had it, then i can’t return it!
Is there a way to test the buttons with adb once I have it unlocked?
it really does just seem like the button is not working
This is a bit old, but basically the side buttons are mapped to keycodes. You can detect KEYCODE_WLAN_ON_OFF and send a debug message to logcat. The tutorial also shows how to remap the shutter button to the Wi-Fi button (the one that you may be having a problem with).
