First of all, as already mentioned, the mod itself it’s no hard to do it or the main cause of a “death system”, second, no one’s here to assure success of anything by files or instructions provide in the forum and done by users or you. It’s or own risk and your asset, you’re the judge of it.
The above “dump/flash” method provided, is based on Intel FPT tool and checking the FD for restrictions or NOT, for sicessful opertaions of read/write.
The used of a common CLIP attached ti the SPI(s) IC (UC2 UC3(vPRO)) is not an easy task and requires acquired experience in dealing with the correct/grip contact with the legs/pins of the IC, most users lack the experience and report as failed, which is common and actable.
Some systems circuit design spi/pch may prevent a correct use of a SPI program, then the desoldering method and outside program is the alternative option to program base/mod files.
Your call sir, good luck.
