| Issue | Solution |
|--------------------------------|--------------------------------------------------------------------------|
| Unknown magic bytes | Use binwalk -e first to detect format. May need manual offset. |
| Checksum still fails after fix | Vendor uses non-standard CRC. Try --crc-algo vendor1 (if supported). |
| Repacked image won't boot | Ensure kernel and rootfs offsets match original. Use --pad-to 0x20000. |
| Missing mk-firmware-pack | Build from source or use firmware-utils package. | | Tool | Purpose | |------|---------| | fwunpack
