Hardware Is it possible to replace eMMC without backups?

[OhItsSlick]

Hey there, so I bought a broken switch off of eBay with the intention of fixing it. As it turns out it was missing the eMMC module so I was wondering if it’d be possible to just insert an eMMC module I’ve got from a donor board are somehow flash it (if that’s the correct term) so that the eMMC can effectively work with the switch? I’ve got no backups for this switch and from what I’ve seen online is that it’s possible but nand backups are required.

I believe it is possible.

You can but only if you can dump the BIS keys. You also won't be able to use it online since it won't have the original prodinfo.
MMC Rebuild from here should work. https://suchmememanyskill.github.io/guides/unbrick/
