Xiaomi/Redmi Qualcomm bootlogo unpack repack tool

Compatibility

This tool is only compatible with Qualcomm devices. Since MIUI 13, bootlogo has been moved to imagefv partition, so this tool is not compatible with MIUI 13 and higher versions.

Before starting, you need to be sure that your device is supported

To do these tasks, extract logo partition, and try to unpack it. If it unpacked successfully, your device is supported.

Note: If logo partition failed to unpack, you can also try splash partition.

Known supported devices:

• Xiaomi Mi 6 (sagit)
• Xiaomi Mi 8 (dipper)
• Xiaomi Mi 9 (cepheus)
• Redmi K20 Pro (raphael)

Important

This tool adds BMP extension to every unpacked file, but this is not always right. For example, dipper has a PNG format (third one) file inside, you need to ignore the BMP file extensions. After changing these different format logos, make sure it is still logoX.bmp

Figure out the real file format with something like winhex or online tool. If you have no idea, check file size. Under same resolution, other format are significantly smaller.

You need to replace the unpacked file with the file in the same format, but you can try different resolution if you have wierd size images unpacked. But, don't exceed your display resolution, and don't exceed your logo partition size.
