@siriusverre @mriesp You can enable sideload mode by: connect the Kobo to a PC, edit your KOBOeReader/.kobo/Kobo/Kobo eReader.conf file (just browse to it like a normal usb stick). in the [ApplicationPreferences] section, add a line that says "SideloadedMode=true" (without quotes.) If the PC is Windows, you need to use a text editor that will respect and keep the Unix New Line convention. (Notepad++ is usually the suggested go to for people to install on a Windows PC.)

However! That turns off all the online functions I think. So you can't use the library service. I think you can just keep using it normally. Kobo is pretty nice on the software side and there are no dozen trackers keeping your wifi active like in Amazon devices.
