BMP – Rearrange Colormap

Posted on February 16, 2026March 1, 2026 by admin

In my limited experience working with BMP, GIMP UI is more intuitive and easy to use in comparison to Photoshop in this particular task, especially when it comes to rearranging colors in the color palette. Also, the image quality after color reduction and shrinking is better effortlessly in my opinion.

Using GIMP

  1. Open Image: Open your image in GIMP.
  2. Indexed Mode: Go to Image > Mode > Indexed.
  3. Set Colors: Choose “Generate optimum palette” and set the Maximum number of colors to 4.
  4. Reorder Palette: Go to Colors > Map > Rearrange Colormap. Drag and drop the colors into your desired order (Index 0-3).
  5. Force 8-bit Colormap: Open the Colormap dialog (Windows > Dockable Dialogs > Colormap) and click the ‘+’ button to add colors, ensuring the total is greater than 16, which forces an 8-bit (256 color) palette.
    ※This is because the index image is reduced to 4 colors, GIMP automatically create a 4-bit (16 colors) map to save space. This will mess up how BMP is displayed in yyCHR.
  6. Export: Go to File > Export As, select BMP. 
Add 13 more colors in the colormap to force the 8-bit Colormap.
You can see the difference in Bit Depth in Properties/Details. On the left is the correct one with 8 bit depth (>16 colors).

Reset Allow USB Debugging? Notification

  1. Go to C:\Users\<YourProfile>\.android and delete both adbkey files, if there are none, skip this step.
  2. Download adb here and extract it somewhere.
  3. Open command prompt and navigate to the folder you’ve just extracted, for example 
    cd C:\path\to\platform-tools
    ※right click on the unzipped folder and select Open in Terminal also work.
  4. With the headset connected and logged in an administrator account, run .\adb kill-server and then .\adb devices.
  5. The notification should appear.

The “Toggle” Fix (Most Common Solution)

The Developer Mode status can sometimes desync between the headset and the mobile app.

  1. Open the Meta Horizon (Quest) App on your phone.
  2. Navigate to Menu > Devices > Headset Settings > Developer Mode.
  3. Toggle the switch OFF, wait about 10 seconds, and then toggle it back ON.
  4. Restart your headset (hold the power button and select Restart).
  5. Plug it back into your PC; the prompt should now appear.
