I installed KSM on my Glo HD and experienced the same problems as flip1314. When applying the updates the screen rotates 90 ° and the close option shows no effect when I tap it.
A pinhole reset did the trick for me. The KSM menu appeared and I was able to start nickel from the menu. Then I installed Koreader and Coolreader as recommended for KSM. For CoolReader I applied tshering's workaround for the latest version 2015.05.
After a reboot KSM regognized both readers.
A few times when I looked something up in the KSM menu, the device startet nickel spontanouesly. I also am not able to change the font size in the KSM menu via usersettings. And yes, I have uncommented the lines (#).
Apart from that everything works fine. I'm a happy reader.
