Even with careful steps, a ZXDZ 01 firmware update can fail. Here are the most frequent issues:
| Error | Likely Cause | Solution |
|-------|--------------|----------|
| Camera doesn’t turn on after update | Wrong firmware file (for a different camera model) | You must recover via serial TTL (advanced). Contact support. |
| Update starts but freezes at 50% | Corrupted file or bad SD card | Re-download the file. Format the SD card again. Use a different card (Sandisk Ultra recommended). |
| “No update file found” message | Incorrect filename or file in wrong folder | Ensure the file is exactly FW9656C.bin (case-sensitive) and on the root. |
| Camera boots normally but no change | You didn’t delete the old firmware from the card | Re-do the process, but after step 5, manually delete the file. |
| Battery drains faster after update | New firmware may reset power profiles | Perform a factory reset (Settings > Reset). Then calibrate battery: drain to 0%, charge to 100% uninterrupted. |
