Hacking back and restore nand question

[blady83]

Greetings. I would like to present a hypothetical nintendo switch bricking scenario in order to clear a doubt i have.

If i make a proper NAND v.5.1.0 backup of a nintendo switch, and in the near future something fails a the NS is bricked, would it be posible to revive the switch by restoring the NAND, or would the efuses prevent any posibility of restoration? This is not a downgrade scenario. The case is trying to restore the same firmware version.

The purpose of the efuse is to prevent downgrading so the nand backup need to be from the same OS version as the console's most recent installed update.

Sure you can restore firmware and some of the nand the none key related areas with a nand dump from a clean nand and see if it works .

And maybe use this to rule out firmware issues .
