My Wii was at 3.4U with HBC, Softchip, Gamma loader, etc by installing IOS16-64-v257-prod.wad. using wad manger 1.1. Then using wad manager 1.3 installed cIOS247-v5fix-ppc_gba.wad, DVDc_247-nw7.wad, BackupLauncher0.3g+249+NeoRame.wad, Softchip v76, Discdumper, cIOS249-v7 & cIOS248-V7. I then did a normal system update to 4.0U through the system. Then ran a patched ios60 wad to get the SD working. All backups/Wiiware, SD moving works fine. I don't know much about IOS's so please forgive if these are noob questions... 1. Did 4.0 update rewrite my cIOS249?-V7 or any other cIOS's? 2. What would happen if I reinstalled cIOS249-V7 or updated to rev8? 3. Since I did the "system" update (not Wanin's pre-installer), do I need to patch IOS61? I already patched IOS60. Thanks!!
