Custom Firmware P.O.C.
Version: ---
Category: NON-VIP-PSP EXPLOITS & LOADERS
Description:
Dark_Alex has released a custom firmware proof of concept!
What is custom firmware you ask? It’s the ability to heavily modify and/or replace the PSP firmware to better work for us homebrew users. This is a big step in the homebrew scene; it was speculated if this was even possible! Well here you go doing it again Dark_Alex, the impossible! For more information on what this actually does, read below:
From Dark_Alex’s website:
Instructions:
(Note: this thing only works for 1.50)
- Copy the PSP folder to the root of your memstick.
- Execute the program “Custom Firmware - The proof of concept”
It will write to the flash some executable files.
Now you are done.
This program has ben tested on my psp. However, as all programs that write to the flash, there is always some risk of bricking the psp. Use it at your own risk.
IMPORTANT (to avoid confussion): the program includes a file called vshmain.prx. This file is NOT of Sony, it comes from me, the source of everything is released.
The features of this custom firmware - proof of concept are:
- Execution of normal pbp’s (1.00 ones, no-kxploited)
- Posibility of hiding corrupt icons. (note: by default it’s not enabled, look at the file /PSP/SYSTEM/config.txt to see how to enable it)
- Posibility of skipping the SCE logo at the startup. (and in this way avoid the annoying auto-execution of the UMD). Like the previous one, this is not enabled by default.
- “Recovery mode:”. If you keep R pressed while starting the psp, it will enter in “Recovery mode”. Recovery mode is not more than a simple application that will let you to use the usb, and execute a program under ms0:/PSP/GAME/UPDATE/EBOOT.PBP, that could be, for example, a sony updater or the 1.50 -> 1.00 downdater.
This would allow to recover potential bricks caused by the writing of bad fonts/videos/sounds… to the flash. (Note that this wouldn’t allow to recover critical things like the overwriting of critical prx’s)
- Autoexecution of a program at the startup. See the configuration file at /PSP/SYSTEM/config.txt to see how to use it.
Warning: Like anything that tinkers with the firmware, there is a chance of bricking your PSP. This is only for firmware version 1.5
