Hello, I follow Koureio guide. I run TBR 1.11 and install IOS 36 patched version on slot 36. (http://forum.koureio.net/viewtopic.php?f=28&t=217) Following this guide, I also installed BootMii and cIOS hermes v5 (instead of v4) and cIOSx rev17. Then I try to run usbloader_gx, i can see games but when I launch the game it doesn't work. Then I read that using TBR 1.11, I should have installed IOS 36 patched version on slot 249. (http://gwht.wikidot.com/ios249) I follow this new guide. I successfully downgrade IOS15. Then I try to install on slot 249. But I have an error at the end : return error -10xx. With error message : your IOS 36 is rev 3351 (if I remember well) or above : installation failed. The wii boot without any problem, I can access to HBC. But now I can't run TBR 1.11. Thanks for your help.
