Several people have mentioned issues using WinDisk32 to write an image. If after following my suggestions, you still have issues, I would suggest either the USB Duplicator Image Writer or balenaEtcher. Do not delete the contents of the .kobo folder. There is no need to do this.

I copy all of these into the empty .kobo folder.
Again, don't delete the contents of the .kobo folder, it is unnecessary. What I would do is to write the image to the µSD card and then insert it in your Touch. Power your Touch on using ONLY the power button since we do not want to do another factory restore. Once it boots up, connect it to your computer. Do not run the Kobo Desktop app. Now I would copy the contents of the upgrade file into the .kobo directory on your Touch and safely eject it. If you see issues with the 4.38.23429, I would also suggest installing an earlier version first. Perhaps 3.19.5761 and then 4.38.23171.

Do not start the device using Home + Power On. That will start the factory restore which is not what you want. Among other things, the update files will not be installed as the .kobo partition will be wiped back to factory.

I log in.
Kobo Desktop says I don’t have Internet, even though I do.

I don’t know what I’m doing wrong, but the result is always the same.
Please help.
Basically, using Home + Power is triggering a factory restore which will remove the update and revert to the factory image. This is not what you want to do. Just use the power button.
