Updating psp m33 firmware
Every time you turn off your console (by holding the switch like 10 seconds) you will have to run the Fast Recovery utility to activate the CFW again.
But If you have a PSP 1000/2000 it’s possible to make the CFW permanent using CIPL_Flasher, if your model is not supported it will tell you so.
In addition to minor bug fixes, this edition of the M33 firmware series of course brings 4.01 kernel support, complete with multi-language support for Recovery Mode.Never put ISO files inside the PSP\GAME folder they will show as corrupted data.If you have OE/M33 firmware lower than 3.52 M33 please start from Section A.
