Thanks surquizu for this great little hack! It works great on the latest FW of my Kobo Glo HD.
Just one problem:
Whenever I use this feature, the Kobo device locks up when connected to my PC and is never shown in Windows Explorer. I have to hard reset with a single click in the pin hole, and then it works normally with the PC as long as I don't activate the nightmode. If I activate the nightmode, even if I deactivate it first, I have to hard reset the Kobo before the PC will see it again!
Any idea if you can fix this??? Thanks!!
Also, how can I uninstall? I want to check if the other hack for nightmode does not suffer from the problem above.
