54w ago - Following up on the MA BD Tool v0.8 for PS3 JFW DH 3.56 MA CFW, today JaicraB has updated the previous PS3 Preloader Advance 2 to version 3 followed by bugfix 3.1 alongside a guide by Chekco via DemonHades below.
To quote, roughly translated: Hi all, as many know, when it published the JFW 3.56 MA-DH commented on the possibility of creating a virtual flasher to downgrade to 3.55 or less, well today is a fact that possibility so from now no one is "prisoner of MA", however it is a dangerous process, it is recommended to keep things clear and know what we are doing responsible are misuse said this.

74w 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".
