So I installed bootmii ( boot2) a few months back, 4.0 firmware. Back then I did a back up of my NAND. When FW 4.2 was released BootMii was also updated. I updated BootMii,HBC and DVDX. Question is, do I need to make a new back up of my NAND? Real Question: If for some reason my wii bricks will the old backup I made work without problems? Thx for your time!
