I have a 3.2u wii with the Twilight Hack that I finally decided to upgrade to 4.x. Been working fine with Oggzee CFG USB Loader with no problems. So I followed the http://www.completesoftmodguide.tk/hacking-guide. I first used HackMii to and re-installed HBC to the latest version and BootMii on boot2. I then made a NAND backup to SD card. Then used the IOS236 installer. So far no problems, no errors. Everything working great. I then used ModMii to update the System. I selected the Wizard, told it my Wii was modded. Selected update from 3.x to 4.1 (recommended). Selected all the channels except Wii Speak. Copied the "COPY_TO_SD" contents to a 2GB SD card with reformatted as fat. Booted in HBC, ran YAWMM using IOS36. Selected all the WADs via the + for 2 seconds. All wads installed fine except I got the following error: Opening "IOS60v16174(IOS60v6174[FS-ES-NP]).wad", please wait... OK! Installing WAD, please wait... >> Installing ticket ... ERROR! (ret = -2011) All other wads installed fine. I tried to re-install this wad again with YAWMM and also tried Wad Manager 1.7 with the same results. I rebooted the Wii to the System Menu. Got the error that the system memory was full. So I deleted the few channels I had installed (like 4 mario games). This fixed this problem but I checked and the system still says it is 3.2u. I tried to re-install IOS60v after deleting the channels from above and still fails. I have now removed all the extra channels like weather, internet, etc using YAWMM but I cannot get IOS60 to install and the system still says it is 3.2u. CFG USB loader still works fine. I even tried re-downloading all of the files with ModMii with the same results. Any thoughts on what went wrong or why I am still on 3.2u or how can I get the Wii to upgrade to 4.1 now would be greatly appreciated?
