    820-02100 SSD REPLACEMENT

    Yes, I tried a USB C cable, but it still 5V, with the same behavior, also when I compared diode mode measurements on the SSD rail with a known working board, it checks out.

    Boots directly into DFU MODE /STUCK IN DFU

    On a side note : Does the machine booting into DFU signifies that all CD3217 are in working conditions? In other words, if I have 5V across but am able to boot the machine into DFU , does this means , my issue isn’t at the CD3217 level ?
