The firmware flash was successful, but the LVDS data mapping configuration does not align with your screen. You must change the LVDS map. Press Menu + 1147 on your remote control to enter the Factory Service Menu . Navigate to Panel Settings and toggle the TI Mode / LVDS Map settings until the display colors correct themselves.

The firmware is the low-level software embedded in the chip. It controls USB negotiation, audio synchronization, EDID handshaking, color space conversion, and thermal management.
Following these steps precisely is crucial to avoid "bricking" your board, which means it becomes completely unusable. 1. Identify Your Panel Details (Crucial Step)
: Firmware packages are often delivered as .zip or .rar files. Extract them locally on your computer to find the .bin or .img flash image.
If you encounter any issues during the firmware upgrade process, here are some troubleshooting tips:
The process usually takes 3–5 minutes. The board will enter standby mode or restart automatically when finished.
The display shows a "No Support" warning, distorted solarized imagery, or split-screen artifacts because the panel's resolution does not match the board configuration.
Stock firmware often uses 4:2:0 subsampling. Modified firmware can force 4:4:4 at lower resolutions (e.g., 720p@60fps) for lossless screen capture.
If the screen is upside down or colors are distorted after the upgrade, you may need to access the Service Menu to adjust the "Mirror" or "LVDS Map" settings: Service Menu Code: on your remote.
For boards that cannot boot, you can use a dedicated programmer like the RT809F. This tool connects via the VGA ISP interface to write the firmware directly to the board's memory chip. This is a more technical approach but is highly reliable when the standard USB upgrade fails.
Save changes and exit to commit the new variables to the system memory.
