| Pre-requisites & Preparation Firmware Preparation: Use an external card reader to copy the system flashing binary file EBOOTSD.nb0 into the root directory of an SD card. |
| Step 1: Remove the Securing Bracket Carefully detach and remove the securing clamps/brackets along with their associated hardware accessories.   |
| Step 2: Remove the Battery Compartment Unscrew the battery compartment cover, remove the protective plate, and safely extract the battery pack.   |
| Step 3: Detach the Rear Housing Locate and remove the six screws indicated by the arrows on the back cover. Gently separate and lift off the rear casing/housing of the device.   |
| Step 4: Insert the Flashing SD Card Insert the prepared SD card loaded with the EBOOTSD.nb0 system flashing file into the device's SD card slot.   |
| Step 5: Expose the Programming Port Unscrew and remove the two securing screws indicated by the arrows to expose the internal system flashing/programming port interface on the circuit board.   |
| Step 6: Short-Circuit the Programming Pins Use an appropriate conductive tool (such as precision tweezers) to short-circuit the designated programming pinholes indicated by the arrow, then temporarily re-insert the battery pack to supply power.  |
| Step 7: Initiate the Flashing Process Press and hold the Power button. The moment you hear the device emit its startup beep sound, immediately remove the short-circuit tool. The screen will display the system initialization prompt: "System upgrade, please wait...".   |
| Step 8: Data Transmission Progress After a few seconds, a progress loading bar will appear on the screen, showing that the system firmware data is successfully being read from the SD card.  |
| Step 9: Flashing Completion Status Once the progress bar reaches 100%, the device will automatically boot into the Windows Embedded CE 6.0 desktop layout, confirming a successful flashing operation.  |
