COMO ACTUALIZAR o CAMBIAR EL FIRMWARE:
Flashing with the official software http://en.qsfj.com/products/3002

If you use Windows, you can use the official updater tool. You can download it directly from http://en.qsfj.com/products/3002

Connect the programming cable to your computer and ensure the proper drivers are installed. In the device manager, it should show up as a com port.

Start the updater tool, select the com port, and click connect.

Load the customized firmware as the program file.

On your radio (still disconnected and turned off), hold down PTT (large button on the side) and turn on the radio while still holding PTT. Now the flashlight should turn on while the rest of the radio stays dark. Your radio is now in bootloader mode.

Connect the programming cable to the radio. The "Update" button in the updater tool should now become available.

Click update and wait for the tool to finish.

All done, all your settings should still all be intact.
