Hacking Its possible to update wrongly a A9LH sysnand?

[yacepi15]

Its possible to update a A9LH sysnand wrongly with Luma3DS? For example, if SAFE_MODE its booted pressing the update button in the eshop and we update. We will uninstall A9?
Thanks.

luma should normally support safemode and prevent FIRM partition writes still.

Well, technically, it is possible to uninstall A9LH with a sysNAND update.
If you use a crappy CFW like Gateway, it won't have FIRM protection. What this means is that FIRM0 and FIRM1, which are where A9LH resides, won't be protected from updates, and the update will overwrite it. Due to the way A9LH works, it'd be a miracle not to brick from this.
But if you stick to Luma, you won't have a problem Luma has the necessary patches to make sure this doesn't happen.

you should be generally safe to update but i would always check on the forums when a new FW comes out.
