18AUG25: This samsung 840 ssd does not detect. It stays busy. Controller: S4LN021X01-8030. Using the safe mode shorting points we had a lot of trouble getting it into ROM MODE, Firmware DXM00R25, 0 MB (). When it did detect in rom mode we had trouble uploading the loader. Usually all the status registers would xmas light up. Sometimes it would come ready but show garbage in the id display.
