Upgrade 3.30 OE-A to 3.52 M33-4

**SyrianPacsis** · October 3rd, 2007, 16:44

I need step-by-step instructions on how to upgrade my PSP from 3.30 OE-A to 3.52 M33-4. I have never hacked my PSP before, my brother did the 3.30 OE-A thing and didn't tell me how he did it. So, I need noob-friendly instructions on how to do this, please.

1st, you will need the official 1.50 and 3.52 sony eboots. get them here;
3.52

1.50
http://www.psp-hacks.com/category/43

okay, now that you have both of em, put them in one folder on your desktop and rename the 1.52 eboot to 150.pbp and the 3.52 eboot to 352.pbp

okay, now get the 3.52M33 installer and put it in your "Game150" folder found in your psp
here;

run it in your psp and follow the instructions.
oh! and put the eboots you downloaded in the same folder where the updater is found.

after it dumps the files, go back to your xmb and back to the game section of the menu and go to memstick, there will be a new icon, "3.52M33 update" run it and wait for your psp to finish installing it. when it is done, youll hafta manually reboot your psp.

now that you have 3.52M33, update it to the latest patch of 3.52M33, which is 3.52M33-4(the most stable one)
here it is;

put it in your game150 folder in your psp and run it.

you should now have 3.52M33-4

feel free to ask me questions, if anything wasn't clear enough for ya.
