upgrade your 3.40OE to 3.52m33 by following this thread:
http://forums.exophase.com/showthread.php?t=2732

Next update it to 3.52m33-4 by downloading from here:
http://exophase.com/files/psp/M33-1234.zip
Place the "UPDATE" under ms:/PSP/GAME/
Run the update and you will have 3.52m33-4

Then, follow this guide to update your PSP to 4.01m33:

1.50 kernel for Add-on seems useless for now so i would recommend not to install it XD
Hope this helps you :smile:
