I so detest the changes in 2.6.1 that I've stopped using the Glo and am considering buying a Kindle. All I want is to go back to the firmware the device originally came with - which is either 2.5.1 or 2.5.2 (I don't know how to find out which version it came with, but I think it's 2.5.2) and then make sure it never upgrades the firmware again - I have no idea how to keep it from automatically upgrading.

I'm not great with computers and technical stuff - to be honest I'm finding using this E-reader somewhat overwhelming/frustrating and I could really use some help in plain English. I just want to relax and read my books!

I've read a couple of threads on this site about how to downgrade the firmware, but the instructions might as well be Greek to me. I'm not a dummy (far from it), but I would really appreciate it if someone would please be kind enough to provide me with the equivalent of "Downgrading Kobo Glo Firmware For Dummies".

Thanks in advance for your help!
To revert to the older version, you will first need to do a factory reset.

Since your Glo is working, the easiest way to do this is to use the factory reset from the Settings menu.

Check the Direct Links to Kobo Firmware link in the Kobo Developer's Corner or download the 2.5.1 firmware from this link: http://download.kobobooks.com/firmwa...date-2.5.1.zip.

After the factory reset, connect your Glo to your computer and let the Kobo Desktop application do it's thing. After that has finished and the eject your ereader pops up, do not eject your Glo. Instead close the Kobo desktop application. You will now need to locate the .kobo directory in the root of your Glo's internal storage (under Windows, you can find it through (my) computer. If you have a Mac, you will need to play some games to see the .kobo directory since *nix style operating systems hide directory names starting with a ".".

In that directory, delete the upgrades directory, the KoboRoot.tgz and the manifest.md5sum files. Open the 2.5.1 firmware zip file and copy it's contents to the .kobo directory (same directory and filenames as you just deleted). Now you can eject your Glo and then allow the firmware update to run.

You will not be able to sync over WiFi after this. When you sync via the Kobo Desktop application, it will attempt to "upgrade" your firmware so you will need to delete the upgrade folder and the two upgrade files before ejecting your Glo.

Good luck!
