After you modify system.img (e.g., rooting with Magisk or replacing launcher), you need to repack everything back into a flashable MstarUpgrade.bin.
The repacker recalculates the CRC checksum and rebuilds the proprietary header. Without this step, the TV will reject the firmware.
| Error | Likely Cause | Solution |
| :--- | :--- | :--- |
| Signature mismatch | The repacker didn’t calculate the correct MStar header. | Use a different repacker version (try v2.5.1). Or flash using ISP mode (bypasses signature check). |
| USB device not recognized (ISP Tool) | Incorrect drivers or wrong UART connection. | Install PL2303 or CP210x drivers. Swap TX/RX pins. |
| TV boots but shows “System service not responding” | The modified system.img is corrupted or permissions are wrong. | Re-extract, fix SELinux contexts using chcon, or restore original firmware. |
| Checksum error during USB flash | The .bin file is renamed incorrectly or corrupted during download. | Re-download firmware. Ensure the filename is EXACT (case-sensitive) as required by your TV. |
