Seeing skriejantis.dari's post about imaging their original SD card and copying it to a new one, I did the same and was able to recover my Kobo Libra 2.
I used the "Flash Drive Image Creator" and "Flash Drive Image Writer" software linked in the Memory Upgrade Mod Guide (With Pictures) post:

I made a full SD card image and wrote it to a new card of equivalent size, and it booted up without issue.
DNSB - let me know if you want me to create an image for you as you requested of skriejantis.dari. If you want one, give me direction on what exactly you are after. I assume it is not the full image that I did to recover my kobo SD card.
