THANKS ALL FOR YOUR CONTRIBUTION, I SUCCESSFULLY REVIVED THE WII USING @person66 METHOD, THANK YOU !!! (also thanks to WiiGator for the cBoot2 Files)
It didn't work because I used a hack to block future updates from Nintendo so I won't lose Homebrew, thank you for your contributionTry getting the entire system update for the console's region using NUSDownloader and install it.
You can use ModMii to recreate the bootmii folder required for using it. Just use "C - Build config files for BootMii..." and copy those to an SD card.
If you have bootmii as boot2 I think you should be able to use WiiGator's cBoot2 to install WADs. Download this: http://www.mediafire.com/download/3hzcoqiec7o0gww/cBoot2+++Wad+Manager.zip and extract it to the root of your sd card. Note that that archive has WAD Manager 1.5 as the boot.dol file, but you should be able to replace this with any other boot.dol (such as Multi-Mod Manager).
Next use something like ModMii to download all your IOSs. In modmii, this can be done by launching it (the CLI version, NOT ModMiiSkin), going to Download Page 1, and typing I, then hitting enter (it should put stars beside most of the IOSs) and then typing D, hitting enter, and downloading everything. Then copy the WAD folder it makes over to your sd card as well.
Next just put the sd card in the wii and turn it on. If you do have bootmii as boot2 (and the sd card is supported, most are, just make sure its 2GB or less) then cBoot2 should start and load whatever you poot as the boot.dol file. From there, just install all the WADs. Hopefully it will work.
You are a legend! I revived it! but first I freaked out cause the Wii didn't launch the boot2 using the microSD SD Card Adapter, later I tried a real SD Card and voila it WORKED! I got into the WAD Manager menu and I installed all my missing IOSes! again Thanks a lot!
Important note to all BootMii users: You cannot enter BootMii in Boot2 using microSD Adapter, you need a real SD Card (I used a SanDisk 4GB SDHC Card)
