1. The compressed file in the link contains the Word tutorial and important precautions - please read them carefully. There are two IMG files in the folder. Please upgrade the RK firmware after exiting the Ulanzi Studio App.
2. The forceps used for short-circuiting must be conductive. First, touch the two contacts with the forceps, then insert the USB cable. Please follow this sequence strictly and check if the RK App detects the new device before proceeding to the next step.
3. If the screen displays a blank screen after flashing the 2.0.3 version IMG file, please replace it with the 1.7.4 version IMG file. Then install the 2.0.19 application version to push the update to 2.0.3. [The download link for 2.0.19 is provided in the Word document later.]
4. After upgrading the firmware application version to 2.0.3, you can update the Ulanzi Studio app to the latest version.
