Preloader .29 fixed the issue where the system menu could not be booted after formatting, so that isn't the problem if the wii has Priiloader. Make sure that Priiloader is set to use the system menu IOS. Even selection IOS 70 won't work because it will reload the IOS. ES_Identify is required in an IOS for the system menu to work, unless the IOS is not reloaded. Also, I doubt that NANDClean could help; instead, it may make things worse.
You may be able to find a program that will take you to the system settings or even data management, if they are intact. If you can just get to the settings, you may be able to access data management. This may provide useful information. PM me if you are not familiar with a program that is capable of this, as the only one I know of is unsupported here.
Try installing Bootmii (as boot2 if possible, otherwise as IOS). If it fails, please post the Hackmii Installer log. If it works, you can use Comex's NAND Formatter to install WADs. If I'm not mistaken, the version of the NAND formatter that I linked to only installs WADs, but does not format the NAND. Therefore, it should install anything in the WAD folder on the SD card. You may have to install one WAD at a time, as some people have reported that it only installs the first WAD.
Try installing IOS 70 and system menu 4.2. Of course, if you try to install a lower version, be sure not to downgrade an "LU64+" below 3.4 or install any per October 23 2008 IOSes on it. Make sure that no other WADs, except possibly the EULA and region select, are in the WAD folder.
If you are only able to install Bootmii as IOS, using Comex's NAND Formatter could fully brick the wii. It is a last resort, and you should only try it if nothing else works.
