Hacking corrupted health safety thing

[kumikochan]

So when i was trying to install FBI over the health safety thing it got corrupted. I didn't make a NAND backup wich was stupid to restore everything but i still got a old working 9.2 emunand from the same 3DS and i was wondering if i could use that as a NAND backup to restore the health safety thing ?

If it's a 9.2 emunand created from a 9.0-9.2 sysnand then yes, but if it's an emunand updated from a lower firmware no, you'll brick your console.

Nevermind, got it fixed using a different method off installing FBI and emunand is now updated without showing black screen when starting. EDIT : Using rxtools and pasta it was showing a black screen again but it works using reinand but whenever trying to install a cia in reinand it keeps saying database invalid hash ....
