EH?

MMM 13.4?

Do you mean the start up IOS? It should be IOS 58 v 6175, if it isn't then download it from Modmii and go from there.

If your asking about installing wads, press left to switch ios, choose (250 if your 250 is like mine: D2X v9 base 57) and you can instal wads from usb no problem, any other non 57 based IOS gives issues.

Hope this helps?

EDIT:

Sound like you did something you shouldn't have, simply download that ios 58 I mentioned, use an exploit to boot to a wad manager of your choice, and reinstall clean 58, then exit, use exploit again to load HBC, then try MMM again,.

Also in the root of your USB/SD card there should be a mmmconfig.txt, try change the AutoLoadIOS=249 to 250 or something other than 52??
