Your guide was clear and concise. For someone new to psp moding, I found it so easy to follow anybody should be able to follow this. You make everything super easy to understand. Thank you very much.

can anyone help me I have a bunch of iso files that I have used winrar on how do I get them to work on my psp please help

[RivaOni]

Got 3.52 M33 to install succesfully, however I don't think I got 3.53M33-4 to install, always goes back to the menu and says "Could Not Get Game To Run (80020148)"

I've put it into the PSP/GAME folder with all the other files (didn't have a GAME150 if that makes any difference...)

i Have 3.40 OE-A Can someone please help and show me how to upgrade to the newest Firmware i am a noob when it comes to this. Thank You

Hey i am on 3.71 M33-4 and everytime i try to update to 3.90 M33 i always get and error with a screen that doesnt let me do anything so i have to shut my psp off then it bricks ¬_¬ did the pandora shit all over again and tried again same thing. Anyone know how to fix this? i wanna update to 3.90 M33

thanks for the guide drew. you help a old veteran like me get to m33 without problems.

one thing id add to the guide is that if youre in OE custom firmware, that u need to substitute the 1.50 folders in the tutorial for the GAME150 folder on a custom firmware equipped psp. i was thinking that i had to downgrade to 1.50 to install m33, but it turns out u can do it from the CFW just be using the GAME150 folder.

Guys,

I have downloaded and read all the NOOBz guides but my PSP gives me an error saying game can not be started when I try to run the kxploitpatcher. Maybe I am doing something wrong? I am running 3.52 on a fat PSP. Any help would be greatly appreciated.

yes, update to at least 3.71m33-2

Hi, just making sure but I am currently running on 3.52m33-4 and I was wondering if I could update straight to 3.71m33-4 or will I have to update to 3.71m33-1 first.

Thanks
