Source a different "hot" version. | | “Upgrade Failed” message | Wrong architecture (e.g., MStar vs Ali chip) | Confirm your board’s main chip. Open the case and read the markings (e.g., M3501, AVL6862). Find firmware specifically for that chip. | | Remote control doesn’t work after update | Remote codes changed | Try reprogramming the remote (if universal) or flash a different firmware variant. Some users fix this by pressing VOL+ and VOL- simultaneously for 10 seconds. | | No signal after update | Tuner driver mismatch | Go to Installation > Manual Scan. Try changing the Bandwidth to 7MHz or 6MHz. Or revert to the previous firmware. | 1509 dvbt2 512m firmware update hot
