128w ago - Here's a small app called n4ru Flash Loader, a successor to JaicraB's Loader, I made in a few minutes. It's completely untested as I have no access to a PS3 until Monday and thus may not work at all, so feedback would be appreciated.
It uses the SynaPS3 library, even though it only uses 1 function from the library. No harm in self-advertisement for my (baby-stage) library?
Jaicrab's Loader was made when we still had to use peek/poke to remount directories. We now have syscall8 (hermes) and syscall35 (PL3) for remounting directories. This makes things much easier.
This loader is universal and works with both Hermes and PL3. Create a folder called "cfw" on the root of your device and place the "dev_flash" folder inside it. Then create another folder called "cfw" INSIDE your "dev_flash" folder.
To quote from his site (linked above), roughly translated:
"This program allows to simulate the dev_flash from USB. Allowing a Custom Firmware. We may modify the files of our new dev_flash (USB) as we please, without running the risk of throwing away the PS3.
It is a beta version, probably find bugs. I will continue working on it when time permits me. Remember that suffers no risk to the console. All that is changed the new dev_flash'll be doing really USB.
• Syscall PEEK and POKE.
1. Copy the "FTP server" the entire contents of the / dev_flash the USB (the root).
2. Copy the JaiC_USB_FIRM_LOADER.pkg also the root of the USB.
3. Install the package.
1. Insert the USB into the PS3.
2. Run USB LOADER FIRM. After a few seconds will return to the XMB. The new firmare is loaded.
