When I make the modification in the kobopatch.yaml I do not have any koboroot file in the out folder

and when I make the modification in the nickel.yaml folder I don't have a koboroot file either but I have a log.txt file with this written in it:

KoboPatch::OutputInit


KoboPatch::ApplyPatches
    KoboPatch::openIn
        Opening firmware zip 'src/kobo-update-4.38.21908.zip'
        --> zip: not a valid zip file

It means that your Kobo firmware file in the SRC folder is not a valid zip file.
Try to download it again and put it in the SRC folder as Instruction No.1 and No.3 on the first page of this thread.
Make sure that you download the Kobo firmware file according to your Kobo Model.

Attached is the image of the SRC folder with Kobo firmware.

Hope it works...
