Thanks for the feedback shaorinor, iv'e followed the guide from step 1.
Except that i cannot run Wadbatchinstaller.dol anymore.
After i choose WADbatchinstaller in loadMii, it loads and checks 2 files and stops at "clearing dss" every time - it doesn't even show the Wadbatch banner.
I think because WADbatchinstaller already installed IOS16 and cIOS249 the last time, and hang.
So is there a way to delete IOS16 and cIOS249 manually?
To make it more clear where Wad batch hang - If you look at the first screen shot at 8 in the guide, it stopped right after:
[+] installing CIOS249, please wait...
>>> Finishing title installation ... OK!
Then nothing....
i'm such a noob
Thanks, R
