Full dump CB2_V8 H3 for WhatsMiner control board - for programming the soldered flash memory chip via a programmer (such as ChipProg48 and similar).
In the archive, dumps were read from working microcircuits TC58BVG1S3HTA00.

If you do not have a programmer and an adapter plate for such a flash memory, then do not buy this dump. This is not a firmware!
In case of failure, no claims will be accepted, go for it at your own peril and risk
