Hey thanks for the guide!
Like others I had trouble with the power switch. Well I completely destroyed it lol.
I should have known better and started away from the switch.
Maybe its more an issue of kobo don't want you to easily open it rather than cost? The unit is super nice inside it even has steel inserts into the plastic case for the internal screws. Very impressed!
Anyways I've got some reed switches coming that I'm going to wire to the power switch then I should be able to power it on and off by swiping it over the magnet on my sleep cover
