102w ago - This holiday weekend Spanish PlayStation 3 developer JaicraB has released PS3 Preloader Advance, a rewritten LV2Diag.self that allows restoring the Dev_Flash.bin file (to fix semi-bricked PS3 consoles) and has been tested on JFW DH CFW although it should work on all Custom Firmware he states.
To quote, roughly translated: Already available the tool to reset any "/ dev_flash". It is but a program that runs without external modules.
Why we find it being unable to load basic libraries housed in the "/ dev_flash" we must use direct syscalls to the kernel. The compilation is clean STUB external modules, hence it only takes a few KB ...
The function is to load the file "/ dev_usb000/flash1.bin" and write in RAW mode to the "/ dev_flash". But not before mounting the "/ dev_flash" Write mode.
It's simple but effective. There are dangers of bricks, but backup mistake or left unfinished for various reasons.
In principle works in all FIRMS, but mainly is designed to JFW-DH356MA by semibricks problems and instead of HDD when the system stored inside the "/ dev_flash".
