Figured. I am using Julian's too...I think.Yes, there are different variants of sysupdater like plaisysupdater or safesysupdater, but they are more or less, inestables too.
I used the sysupdater that was in the same thread that the 9.2 pack I used in "that iso site" (I thin it was julian20's version).
I would recommend plaisysupdater or that julian20's sysupdater but either way you'll probably need to try more than once to get it run
Is the a9lh the way to go instead of the carts? I almost bought another Gateway 3ds cart for my new 3ds. I haven't looked through the guide yet.
