Thank you for your reply. I am aware that updating sysNAND on a9lh is considered safe, but I plan to leave it at 9.2 because it has alternate entry points on the off chance that I somehow lose a9lh. I know it's quite unlikely to happen by accident but a lot of kids mess with my consoles and in general I'm a very unlucky fellow. Also, I'm migrating from menuhax after almost a year, so I'm a bit paranoid about doing anything on sysNAND. emuNAND seems cleaner, and space/speed is not an issue (64gb class 10). I plan on updating emuNAND to latest firmware.
So, I would not have to do anything different in the steps latter to the update skip? I will use hourglass to create emuNAND, unlink, and set luma config to autoboot emuNAND.
