To downgrade firmware:
  1. Get anything off the device that you don't have elsewhere.
  2. Do a factory reset. You can do it from the settings or using the buttons.
  3. Wait a bit.
  4. When prompted to setup, connect to the PC and use the Kobo desktop application to setup the device. This will download the latest firmware and put it on the device.
  5. When the application has finished and asks if you want to eject, choose the option to continue without ejecting.
  6. Open the drive for the device and go to the ".kobo" directory.
  7. Delete the files "KoboRoot.tgz" and "manifest.md5sum" and the directory "upgrade". Depending on the firmware version and the device, these might not all be there.
  8. Unpack the firmware file you want to use into the ".kobo" directory. You should end up with the same files and directories you delete above. Make sure you have the correct version for your device.
  9. Eject the device.
  10. Wait for the firmware to install.

That is what I do. There are ways to skip using the desktop application if you don't want to login to a Kobo account. A search here should find them.
