Force Flashing

⚠ Warning

Only perform force flashing when flashing fails and the port is not recognized.

If flashing fails and the port is not recognized, you need to use the "2nd Generation Qualcomm Engineering Cable V2.0" to assist in forcing the device into flashing mode. This cable can be purchased by searching "二代高通工程线V2.0" on Taobao.

Follow these steps to enter force flashing mode:

1. Disconnect power from the 2nd Generation Smart Camera.
2. Connect the Type-A end of the Qualcomm engineering cable to the PC.
3. Press and hold the round button on the Type-C end, then insert it into the 2nd Generation Smart Camera's Type-C port.
4. Open the QFIL flashing tool on the PC and check if the 9008 port is recognized. If not, repeat the operation.
5. Once recognized, release the round button, then power on the 2nd Generation Smart Camera and proceed with flashing.
