Then I'm out, sorry.It does support php, and i do think the exploit uses php, because there are .php files withing the file.
Only thing people told me when I had nothing but freezes after I bought my Wii U is "keep running the exploit even if it freezes, once it doesn't freeze it won't freeze any time again".
To be honest I wasn't patient enough for this "solution" and used a different kernel exploit then.
