| Update stuck at 50% | Network interruption or browser timeout. | Do not turn off power. Wait 10 minutes. If still stuck, you need recovery mode (see below). |
| Router won't turn on after update (Power light blinking slowly) | Corrupted firmware (bricked). | This is recoverable. Set your PC’s IP to 192.168.1.10. Open a TFTP client and re-flash the original firmware. |
| Can't log in after update (password not working) | Firmware reset to factory defaults. | Use default credentials (admin / admin). Check sticker on router for unique default passwords. |
