DO A NAND BACKUP NOW !!! LOL.
Are you sure you want to install Cioscorp, remember it REPLACES EVERY IOS ON YOUR Wii WITH Cios's.
i use it and have never had a problem, but there are people who are very against it. mostly them who only have Bootmii as IOS and are just scared LOL
So what to do now
1. DO A NAND BACKUP.
2. INSTALL Cios38 REV14 ( IOS249 ) IF YOU DO NOT ALREADY HAVE IT, LINK TO IT IN MY SIG ;-)
3. INSTALL CIOSCORP V3.4(Link in my sig)
Once again, if you are certain you want Cioscorp, Just let the installer do it's thing it's all automated, but do NOT switch off your Wii, power it down in any way during the installer running, this will brick your wii.However the good news is you have Bootmii as boot2( are you deffo sure YOU HAVE IT AS BOOT2?? LOL)
Oh and did i say do a NAND backup NOW LOL.
To double check you have BOOTMII as boot2, because it's important, when you turn on your wii do you see the blue LED light flicker twice very fast, in the space of a second?
Also you can check by putting the Hackmii folder back on to your Sd card, put SD card in Wii, Turning on your system and it should boot direct to this screen.
If you are certain you have Bootmii as BOOT2 and you have your NAND backup saves somewhere you can now proceed to install Cioscorp.:-)
I really need to go to bed now, so ill check back in the morning to see how you got on. you will be fine though.
Good luck and Good Night.
p.s you can navigate the Bootmii options using a GC controller or the Power button and reset button on your Wii.
If you are now certain and have a NAND backup then you can proceed :-)
