Verification error during NAND-Flash update
When starting-up the machine or re-stating it from the energy

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.
