| Service code expired or invalid | You entered a code meant for v4.1 or earlier. | Regenerate a v4.2-specific code. |
| Service mode locked – too many attempts | 5 failed attempts in 10 minutes. | Wait 24 hours or power cycle with dip switch 3 ON. |
| Service code required for downgrade | Trying to roll back to v3.x. | Not recommended; v4.2 changes the NAND flash layout. Use code only from support. |
