I tried to understand his problem yesterday, but it was very late at night (now I'm very sleepy at work).
Here what I understood:
- He had HBC (I don't know which version)
- He deleted it (I don't know why)
- He want it reinstalled
- He is on 4.3
- He has a code dump when accepting the Installation of HBC (so, inside hackmii installer)
- He tried 5 different SD cards (I don't know which format or size)
- He said other homebrew also give a code dump when using them, like USBloaders/Wii64. (he said he launched them using MMM. It can launch homebrew? I never used MMM, I assume it can.)
- He used modmii to get MMM launch with letterbomb instead of Hackmii installer (I didn't know modmii guides allowed that)
- He used MMM to install some Wads (I guess they are official unpatched wads, right? Modmii has a guide to install some wads before launching hackmii installer?)
- He tried to launch cIOS d2x installer from MMM (using IOS249 as base, or trying to install IOS249, I didn't understood). Then it code dump too, on "3rd tab".
- when he select 249 he has "error mounting SD card" message.
Maybe he just has his SD card in Write protected mode.
But he said he could install bootmii (so I guess he also could write the bootmii files on SD, along with the install log), and I don't think HBC installation require any SD card writing except the logs.
I tried a write protected SD card with a USBloader and I didn't get any code dump, it just act as if the SD card was unmounted.
But anyway, check your "Lock" switch on your SD CARD!
