download all recommended cIOSs
start MMM
*go to the very last option in the list and reload to 236
back at the MMM menu, start the WAD manager and install the recommended cIOSs
if it fails go back to the *previous step and choose 249 or 250.
if they fail too, report back
edit: just realized I got your case mixed up with someone else who couldn't use their wiimotes. If you can't follow the above instructions either use ModMii's syscheck updater or ModMii Wizard to update your softmods
open the folder where ModMii.exe is saved, right click and make a new text document, rename it from "New Text Document.txt" to "whatever.bat". Then open it using notepad and copy\paste the following text into it, save it, close it, then double click whatever.bat. It will download everything to update your HBC, install IOS236, and install the recommended cIOSs as well as generate a custom guide for you to follow
Code:
ModMii.exe W 4.1 E Min HBC REC 236 CMIOS:D UIOS:D FWD:D
Note,
in this case it doesn't matter that the guide was generated for 4.1E, the steps will be the same for all system menus (except for the exploit, but you can just skip the exploit and load the hackmii installer directly from your existing homebrew channel, which is indicated in the guide anyways)
Also, note that there is more you can do to update your softmod, for example if u don't have priiloader installed, you should just run the ModMii Wizard and tell it your Wii has never been modified before and follow that guide instead.
