2/23/2024 0 Comments Toshiba challenge code![]() All the information indicates that the password is stored in the Flash chip (00000-FFFFF), to be more precise in Sector with address D0000-DFFFF. I was able to take a reading of the Flash chip, a ST M50FW080 8Mbit before I paid for a service to remove the password. Posted: Fri 9:23 am Post subject: Update. Can someone confirm this, where's the password stored? and if anyone has an image file of the flash chip or a way of how to extract it from the Toshiba firmware update executable so I can remove the firmware chip and overwrite it?

Doing some research about this particular model, found a site that has some information as to which locations of the EEPROM memory to modify in order to bypass the User and Supervisor password.
