I think I just bricked my first Wii I had a friends Wii (4.3U) that had almost no free memory (84 blocks) so before I modded it I tried to delete some of the bigger junk channels that he had sucking up memory. I tried killing the Internet channel but after waiting 10 minutes I restarted the Wii. Tried to go back into data mgmt/channels but nothing showed up and it hung. I figured what the heck and tried a Format memory but it hung after about 15 min I rebooted. I then used LetterBomb to install HBC and installed Priiloader and Bootmii (as boot2). I didn't take a NAND backup at this point So I tried a title deleter and was able to delete some stuff but when I tried deleting the Internet Channel it kept hanging. So I then tried to install 4.3(U) but didn't have the files on my SD and forgot to connect it to my Wifi. I believe at this point my Priiloader was removed. So I tried to install the Internet Channel over the existing one thinking once I install it, it may fix whatever corruption and then let me delete it. But it hung during the install. After 15 min I pulled the plug. Now I get a black screen. With the SD card in I can get to the BootMii menu but it blackscreens trying to load HBC or the System Menu. I took a backup of the NAND but don't know what good it is going to do now unless there is a way to fix whatever corruption is in the NAND and restore it. Any suggestions would be greatly appreciated. Thanks!
