Config file recovery

Hello. Maybe somebody here would be able to help me.
My PC i my shop died, with backup of my config files for my custom delta build.
I wanted to make a backup again on the new PC, so I turned my printer, which have been laying and waiting for me a half year, and what a surprise, brand new samsung SD card died, just by sitting in my mainboard. I managed to recover those data from boot partition, and I was wondering, If it is possible somehow to extract my config files from those? Or is it lost forever? Any help appreciate.

No, your printer config file won’t be in the boot partition. I’m not sure what “died” means to you in this context, but there are many things you can do to try to recover data from the main partition.
