Im on 3.40 OE-A and i want to go to 3.71 M33, can someone tell me how to do it. THNX
Here you can find the 3.52 M33 update files.
You will also need the 1.50 EBOOT and 3.52 EBOOT files. You can get these here and here:
Ignore the instructions on the Sony website, just get the file from "Download procedure" step 3.
You will have to extract the 1.50 EBOOT file, but the 3.52 file is already extracted. Name the 1.50 EBOOT to 150.PBP and the 3.52 EBOOT to 352.PBP.
Now take the M33CREATOR folder and place it on your PSP at this location: ms0:/PSP/GAME150/
Now place both the 150.PBP and 352.PBP files into the M33CREATOR folder on your PSP.
You can now disconnect your PSP from your computer and run the update. After it has finished it will have created another icon on your PSP, run this, after that has finished you will have firmware 3.52 M33.
Make sure your battery charge is above 75% and/or has a charger plugged in before you do the update.
You need to stop linking to the PSP page for the 3.52 EBOOT because it is 3.71 not 3.52.
You can get the 3.52 firmware HERE
Also after you update to 3.52 M33 you should add the #4 update patch which you can get below...
3.52 M33-4 HERE
Now extract the 3.52 M33-4 update.
Drag the PSP folder that is in the update M33-4 into the root of the MS overwriting the files when it asks you to. Now go to Game Menu Memory Stick and run the m33-4 update. This will only take a few seconds.
After the update is finished check and make sure it says 3.52 M33-4 for firmware. If it does say 3.52 m33-4 then format the MS 1 more time.
You are now updated to 3.52 M33-4.
not 3.52 i need 3.71 m33....sorrry
You need to go to 3.52 M33-4 before updating to 371 M33.
Here is the 3.71 M33 CFW (Make sure you update to 3.52 M33-4 first)...
read the read me file to get directions on installing.
