That looks like it should work. It is basically what is being done with the images.
The things I would try are:
- A new card. I don't know why you are doing this, but, if there were problems before, it could be a failing card.
- Use the image without changing the serial number. It will be safe to reuse at least while you prove the process.
- Charge the device. Don't assume the charge level is what it was when you last used it.
- Do a manual factory reset according to the instructions on https://help.kobo.com/hc/en-us/artic...or-Kobo-Elipsa.
Other than that, what actually happens when you use the image? Does the power light come on? The screen change? The front-light do anything? The last suggestion above won't do anything if the device does not start at all, but, it can solve problems after an image is used.
