This firmware update broke my glo

The touchscreen becomes nonresponsive.
After fresh boot the system recognize my touch only once, but then the screen freeze.
Mine is from Rakuten, I changed the affiliate from RakutenIchiba to KoboIndigo.
Haven't had issue any issue updating until firmware 3.1.1.
No Idea why this happened.
Factory reset seems to fix the issue, although it still sucks to lose my reading stats.
