Hi, my Glo froze on the recharge screen recently, so after all else failed, I had to do a factory reset. Then I installed the latest update via wifi from the kobo server. This lasted 2 days, before freezing while reading an epub, and strangely, the back light stayed on too. It's still frozen. The usual reviving methods - recharging, factory reset, using the paperclip button, using all buttons etc. haven't worked. My computer, a mac, does not see the device. When you move the power switch, you get a blue light on the led, rather than the previous green one, which lasts for about 8 seconds. Nothing else happens. I think I read somewhere that kobo have disabled the factory reset in recent firmware updates? Anyhow, is there anything i can try before sending it back?
Thanks
