Problem:
When upgrading Xhorse Multi-Prog firmware from v1.36 to v1.45, the update may fail with the error:
“Jump Recovery error: 41330004 – fails to communicate with the SC chip.”


Solution: Forced Upgrade
- Power off the device.
- Press and hold the Reset button.
- While holding Reset, power on the device.
- Keep holding for about 5 seconds, then release.
- Retry the firmware update.



This method usually restores communication and completes the upgrade successfully.
