Hi,
After swiping the screen, be sure to dial out the SD card. Otherwise, it will automatically refresh the screen upon power on.

Hi, you can download this UI file and update it.
and you need to remove the SD card after the update is complete.

Hi,This firmware is incorrect.The following are the correct firmware and Ui files:
Motherboard firmware: A30_M07_V0_01.bin (CRC32: 4E6ED0BA)
LCD screen firmware: A30_S02_V0_01.bin (CRC32: D65698E0)
1. First burn the motherboard firmware: use the "firmware_tool_V2.0" burning tool for burning, and it must be the firmware_tool tool of version V2.0 or later.
2. If the screen is still black, burn the screen firmware: use the "firmware_tool_V2.0" burning tool to burn.
3. If the screen is still black, refresh the UI: save the system in the UI file to the SD card, insert the Sd card into the card slot, the screen starts to refresh, the refresh is completed, and the Sd card is pulled out.
