"SSS" stands for Solid State System, a major manufacturer of flash controller chips. The is the specific controller model name utilized by the developer. In many cases, Toshiba licenses or rebrands these SSS controllers under their own part numbers, such as TC58NC6623. For all practical repair purposes, these two names refer to the exact same hardware architecture. What is an MPTool?
Open the main MPTool.exe or ISP.exe application. tc58nc6623 sss6698-ba mptool
