Hi everybody,
I would like to know if anyone has a direct dump file from a TOSHIBA Satellite of series C8XX/L8XX to put directly in my notebook ?
Here's the story :
Some bad guys from work put a Bios master password in my Toshiba satellite L870 notebook.
I have all the invoices that can prove it's mine, and already asked on another community forum (less specialized, no answer, though )
Since I like to test things, I bought a bus pirate and a pomona SOIC Clip to dump the actual file of the chip.
The chip is a W25Q16BVSIG and the Dump is posted here its weight is around 2 MB (200000 offset in hex)
I downloaded from Toshiba the original Flash update that weights around 4MB
When comparing the two files, the near 75% is of the same composition, then I think that the Toshiba original file contains instructions for the controller to update the Bios.
The problem is that I'm not an expert at this, and even if I tried some modifications onto my dumped file, it only bricks the notebook. (Recoverable to original state, thanks to my bus pirate)
I have checked some of the Flash unlocked bios here on the forum that shares a lot of similarity with mine (so C850 and alike can work)
I have also a W25Q32 chip on the motherboard that has some strange instructions in it, but I do not think it has to do with my bios directly, see dump here
Any help would be greatly appreciated.
Best regards,
Chakiral
