BLUETOOTH · DESKTOP CHROME OR EDGE · EXPERIMENTAL

Boot logo

Replace the TD-H9 startup image with any PNG or JPG. The radio needs H9 Toolbox Firmware, installed from the Firmware update page. The image is converted in your browser and never uploaded.

Before you begin

The logo is stored on the radio's separate resource flash, so firmware updates (including a return to stock) keep it. Writing erases and rewrites only the logo's own sectors, each after checking it still holds what was just read, and reads the whole logo back at the end. Save the current logo first: choosing that .bin later puts it back.
