I have just return to see what is new on the psp and I can see that my 3.52 M33 CFW is out of date. I am trying to upgrade it to 3.71 M33 but I first need the files of m33-4 (correct me if im wrong). But I dont know where to find the files. I have followed the guide, but it doesn't give the link for it. I went to the main site where the CFW can only be downloaded but I do not understand the font. Please help. Thank you in advance.
