I was having trouble connecting my Kobo to my computer (and fortunately found the solution in one of the other posts here - connect it to a different USB socket) but before that from googling had tried updating the firmware, which I hadn't updated for 5 years. Seemed like a sensible thing to do, although it didn't enable my device to connect anyway plus it changed the whole display making my Kobo difficult to use. Okay so I'll just try to get used to it, I thought. But when I next went to connect with Calibre I got the error message below!! So now I can't use Calibre with the updated Kobo firmware. I searched this forum and couldn't find out how to restore the old version of Kobo firmware so I can use Calibre again?

Many thanks in advance for any help



calibre, version 5.34.0
WARNING: Failed: Kobo database version unsupported - See details

Your Kobo is running an updated firmware/database version. As calibre does not know about this updated firmware, database editing is disabled, to prevent corruption. You can still send books to your Kobo with calibre, but deleting books and managing collections is disabled. If you are willing to experiment and know how to reset your Kobo to Factory defaults, you can override this check by right clicking the device icon in calibre and selecting "Configure this device" and then the "Attempt to support newer firmware" option. Doing so may require you to perform a factory reset of your Kobo.

Discussion of any new Kobo firmware can be found in the Kobo forum at MobileRead. This is at www.mobileread.com/forums/forumdisplay.php?f=223.

Device database version: 166.
Device firmware version: (4, 31, 19086)
This firmware version is buggy. Get 4.30 something instead. Just unpack the zip file to the .kobo folder. Safe eject, wait for your kobo to update and keep the wifi turned off or it will sync back to 4.31.something, which is da pest and the horror!
