Hacking How to handle A9LH TWL_FIRM?

[Maximilious]

I'm working through installing A9LH on my O3DS and I know I've installed an older TWL_FIRM on it for GBA games at one point. It mentions removing TWL_FIRM, but I'm wondering if it needs replaced with it's previous version before the downgrade, or if deleting through FBI is enough without replacing it.

I'm at the downgrade step in the guide, but probably won't get to that until tomorrow or the day after. I want to make sure of this since I've read having the old one in place has caused some bricks for some users here.

You mean AGB_FIRM?

AGB and TWL firms. Download them with 3DNUS, install with FBI.

OK, so the guide is wrong as it should say "replace" not just remove. And yes I was referring to AGB and TWL. Thanks!
