Thanks, I'll search for it!

Well I am fairly sure that @geek1011's page is wrong. I know that the Glo will factory rest to 2.1.something. As it became available in early October 2012, the firmware released at that time should be the first firmware for the Glo. But, there is no easy way to prove it at this point.

Hi Everyone,

So it's not looking good right now. I first successfully downgraded to version 2.10.0 (I registered using a random e-mail, it updated to the latest version, then I was able to downgrade to 2.10.0 by putting the files in the .kobo folder and ejecting. After that it remembered my registered e-mail address, so no more need to register).

2.10.0 worked. I wanted to try 2.5.0 for comparison, and downloaded the firmware and once again put the files into the .kobo folder. I ejected, and the update (downgrade) started... but it is going on and on... indefinitely... the five squares in the center of the screen are filling up successively, to indicate that a process is happening... but it has been going on for upwards of 20 minutes now I think. And If I connect via USB to my computer again, the Kobo doesn't show up this time. Nor can I turn it off. As it is in the middle of updating.

I believe this is what is known in the lingo as "bricked." Can I do a hard reset, I suppose, by inserting a sharp object into the little hole at the bottom of the device? Or by some other means?

UPDATE: Whew! I followed the manual reset instructions on the Kobo help website and it is now "restoring," so I seem to have avoided the dreaded bricking. I'll try with another firmware...

Have you actually tried using the current firmware on the Glo? I know you said you tried other devices but none of the current Kobos use the screen the Glo used. You might be doing a lot of unneeded work.

Just because Kindles firmware gave you issues doesn’t mean you’d get them with Kobo.

I've had a Kobo Aura H20 for just over six years. I've done numerous firmware updates. Not once did I see the firmware causing any issue with the screen.
