You need to extract the kernel and ramdisk from the raw dump and repack it. This requires unpackbootimg (part of android-tools or mkbootimg package).
On Debian/Ubuntu:
sudo apt install android-sdk-libsparse-utils android-sdk-ext4-utils mkbootimg
Conversion steps:
# 1. Create a working directory
mkdir boot_conversion && cd boot_conversion
Before diving into conversion, it is critical to understand what these file types actually represent.
Cause: Corruption in the original .emmc.win or insufficient permissions.
Solution: Verify the .md5 checksum using TWRP or md5sum command. Re-copy the file from the original backup location.
If boot.emmc.win is uncompressed, you can often just rename it to boot.img. TWRP backups of emmc partitions are usually raw block images. However, TWRP may compress the backup (using gzip). So the first step is to check if it’s gzipped.
