Innovations :
- Emulation of firmware 3.90
- Bug fixed of the NO UMD function which occurred at the time of game interruption via the HOME key.
- Added code to download the 3.90 eboot from net via WIFI connection.
- Method to bypass battery charge check has been restored by pressing at the same time L + Triangle buttons. If you already have 390.PBP keep those buttons pressed until you see "Veryfing 390.PBP".
- If the 390.PBP is being downloaded via wifi, press those buttons at the end of download until you see the previous sentence.
PS: The main installer will not install 1.50 kernel anymore. A 1.50 kernel addon for 3.90 M33 is available (for PSP™ Fat only).
Note: Due to some changes in kernel nids by Sony, you can expect a lot of kernel plugins not working anymore.
NB: To install this update you must be at least in custom firmware 3.52 M33-4 on PSP™ or custom firmware 3.71 M33 on PSP™ Slim.
The battery must be charged at least to 78% and the power supply must be connected.
Place the files at the root of your Memory Stick™ then go in Game --> Memory Stick™ and launch the update while pressing on "Cross".
CAUTION: Once finished, the installer will ask you to start again, to make this action press on "X" or "O" buttons... Do not escape this stage by switching off your PSP/PSP™ or your console will be bricked.
