Prepare 1 to 4 M.2 NVMe SSDs for upgrade/installation.
Install the M.2 NVMe SSDs into the device’s M.2 slots.
Connect the device to the PC via USB cable, power it on.
Upgrade Notes:
1.This upgrade will not cause data loss or damage to the M.2 NVMe SSDs, but we still recommend backing up your data as a precaution.
2.During the firmware upgrade, close any Windows applications that may be accessing the M.2 NVMe SSDs to prevent update failures.
3.Do not modify any parameters in the UTHSB_MPtool_Lite tool to avoid upgrade failures.
4.Disconnect other USB devices to prevent accidental operations.

2.Save the file to your Windows desktop and extract it to the current folder.
3.Open the UTHSB_FW folder and run the UTHSB_MPtool_Lite application.
4.In the upgrade tool interface, check whether the device is successfully connected. If the Port1, Port2, Port3, and Port4 interfaces in the list can display the M.2 NVMe SSDs normally, it indicates successful recognition by the computer.
If you only have one M.2 NVMe SSD but need to upgrade other M.2 slots of the device, after completing the upgrade, install other M.2 SSDs and click upgrade again.
5.Confirm that the device is recognized normally, then click [Update Device] to upgrade.
