you don't need ANY IOS200+
no need of 236, 249, 250, 251, or any base56/57/58
Im getting the same screen as before saying HW_AHBPROT is disabled.
this is a
GOOD THING !
This is NOT AN ERROR!
it means you disabled the AHB
PROTection normally preventing you to install WADs.
You need to answer "NO" when it asks you if you want to reload to another IOS "anyway" (meaning: why would you want to do that? you already unlocked your console), because NO you don't need to reload to 236 anymore (don't follow old guides telling you that you need to), you already unlocked the protection
At this step: press A !
and then, proceed to install your wads.
be sure you are using Fix94 version !

About IOS80:
you'll need to patch IOS80 if you plan to move channels onto the official SD Menu. if they are on SDMenu, you can't launch/move back to internal memory if you didn't patch IOS80).
if you install the game on internal memory, then you don't need to patch IOS80.
