Reprogram reset button

Hi forum folk,

I have seen some old posts about people customising the reset buttons on their devices for alternative functions.

I also note the toggle button (present on some models) can now be bound to different functions.

I have a Spitz Plus and want to reprogram the reset button to toggle the active SIM between slot A and slot B.

Is there a best practice for doing this? Things to consider?

Thanks all.

What to do if you need the reset button?

This operation will not support, please do not that.

When you really need to rescue the router, how do you reset or unbrick it?
