KOReader running on BQ/Fnac devices
BQ no longer exists. Instructions here no longer work. If you're running stock you're out of luck.
People running Developers FW are ok as long as don't flash back stock. Feel free to ask for help if you manage to brick your device (
but, how?). There're ways to fix it without reverting to stock.
Also if somebody wants to send me an old device (from the list below, in original instructions) send me a PM. I can't promise a workaround but I promise I will take a look
