Maybe this question has been asked before but I didn't find it and I'm stumped on this. I finally got this v3.51 psp and I'm trying to upgrade it to 3.52 firmware so I can finally run CWcheat. Now I followed the instructions on this site (
Universal PSP M33 Installation - Sony PSP Mod & PSP Hacks Forums), Got the eboots for both 1.50 and 3.52, loaded them in the 3.52M33 creator, and I still get the error code 80020148. So what am I doing wrong? Is it just impossible to upgrade from this level or what? Can someone please just give me an idiot's guide for how to do this?
