I was presented with a VCS exhibiting the same error code LED flash sequence. Re formatted the card as suggested on the forum, no improvement.
On board is a small lithium button cell reading a terminal voltage of 0.45V instead of 3-3.3V.
Had a new 2032 lithium cell on hand as well as a holder to suit, grafted the holder onto the PCB, added the cell and cured the problem. A word of caution here, the overlay on the board looks like the image of the cell holder, however the orientation is incorrect, beware of the cell polarity and ensure it matched the original with positive terminal toward the outside of the PCB, use original holes if possible to mount your new cell. No error codes anymore, just a fast LED flash indicating a ready state.
