I own Kobo Aura One (not limited edition) and currently have KSM with Koreader installed. However device is really overcrowded and for a long time the battery only held for few days. I'd like to clean it up completely and install Nickelmenu, Koreader and preferably a friendly program for reading manga. What steps should I take? Do I have to remove KSM manually, using these instructions
