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.
You will see that whatever you do the USB will be launched. Ideal for amending RCO, exchange modules, as you imagine.
Do not update while in Live Firmware Mode. It will reboot, setting the original dev_flash back, and then it will update! Do not update from USB FIRMWARE LOADER!"

What we need is someone to get the METLDR stuff working, "From metldr you can load up every other "ldr"'s (take a look at Hypervisor RE!) Using those loaders you can decrypt EVERYTHING from self's to pkg's".
I put a copy of 3.42 and when I loaded this it asked me to press select and start to look for new firmware. It couldn't find anything but this never went back to XMP I had to Force Shutdown. I don't understand how it works or what it loads?
Well luckluca said that he was able to access the psn store with this fw loader. Does anybody know how he is pulling this off?
Luckyluka if you need my dev_flash then let me know please and i'll send it to you or if you would just let us know exactly what you did then i would really appreciate. I would really just like to access the store to get a few things on my jailbroken ps3. It would really be nice just to have all my stuff on one console you know. Thanks.
Someone with XML coding experiens should realy look into the xmb xml files. I made a copy of the category_game.xml, and renamed it to category_photo.xml, and replaced the original. So now the games and the other stuff show up under "Music". The "Memory Card Utility (PS/PS2) folder did also appear! I can't see it under "Game" when i am using the JB....
In the category_sysconf.xml there are two hidden options that is not shown in the XMB. "edy" (edyviewer) and "console_qa" (tool_debug_settings)
Is it possible to add a code thats starts "console_qa", insted of "update", when the you start "System Update"?
