Verification error during NAND-Flash update
When starting-up the machine or re-stating it from the energy saving, the machine reads the state
of the NAND-Flash and detects that there are defective blocks whose amount exceeds the
threshold. This means that the life of the NAND-Flash is near-end.
Near-end Life of NAND-Flash
Replace the controller board as soon as possible.
