I didn't expect that to work - those .DOL->ELF generally are for older GC stuff.
2011 is a signature check failure (non-exploitable or usable IOS)
The hanging most likely is due to the fact that 249 is using a base for a Wii and not vWii therefore any calls to it go to the wrong places in memory.
You could try 36 - but doubt it would work.
One other thought - go back to HackMii installer, and let it hang on the scam screen. On the SD should be a file that has a dump of the HackMii log. Perhaps post that here to see what is actually installed on the system.
Without a vulnerable IOS or CIOS you won't be able to install anything. Hopefully you can get it fixed or you may be sitting with a brick
