We can duplicate our real Firmware (Flash 1/2/3) to the Usb-Stick and restart the console loading it from Usb. We can test altering the Firmware on Usb and check it out. Firmware Update will update the real Firmware. We need Peek+Poke to get it working.
If anything is wrong, please say so to make it clear.
This program let you emulate the dev_flash from a USB. Allowing a Custom Firmware to be loaded.
We can modify the files on our new dev_flash (USB) as we want, without the risk of bricking our PS3. This is a BETA version, it will have some bugs.
I will keep working on this on my free time. Remember that there is no risk to the console. Everything you change on the new dev_flash will really just be on the USB.
1.- Syscall Peek and POKE.
1.- Copy all the content of the /dev_flash to the USB stick root folder via "FTP Server"
2.- Also copy the file JaiC_USB_FIRM_LOADER.pkg to the root of the USB Stick.
3.- Install the package
1.- Insert the USB into the PS3.
2.- Execute the USB FIRM LOADER. After a few seconds you will be back to the XMB. The new Firmware is loaded.
You will see that whatever you modify on the USB will be launched. Ideal for modifying RCO, exchange modules, whatever you imagine.
Do not update using the Live Firmware mode. Is will restart the system, back to the original dev_flash and update it.
No UPDATE FROM USB FIRMWARE LOADER!"
