If you are looking for a way to easily unpack / repack boot.img, recovery.img or logo.bin from your MediaTek device, don't look any further. Here you can find my own Perl scripts.
Scripts were first based on the ones available on Android-DLS WiKi, but are now highly modified in order to work with specific MTK boot and recovery images. The scripts fully work with every image from all known MediaTek SoC:
- MT6516
- MT65x3 (MT6513 and MT6573)
- MT65x5 (MT6515 and MT6575)
- MT6577
- MT65x2 (MT6572, MT6582 and MT6592)
- MT6589
- MT83xx (MT8377 and MT8389)
- MT6595
Usage: unpack-MTK.pl <infile> [COMMAND ...]
Unpacks MediaTek boot, recovery or logo images
Optional COMMANDs for boot or recovery images are:
-info_only
Display file information only
(useful to check image information without unpacking)
-kernel_only [--debug]
Extract kernel only
-ramdisk_only [--debug]
Extract ramdisk only
(optional argument '--debug' can additionally be used to provide useful
information for debugging purposes, even while unpacking both kernel
and ramdisk)
Optional COMMANDs for logo images are:
-force_logo_res <width> <height>
Forces file to be unpacked by specifying image resolution (in pixels)
(only useful when no zlib compressed images are found)
-invert_logo_res
Invert image resolution (width <-> height)
(may be useful when extracted images appear to be broken)
- Note: for the new platforms requirements, the unpack script will now display the complete information about input image (example shown bellow) and also create an extra file with arguments needed for further repacking.
Input file information (example):

Second stage offset: 0x00f00000
Tags offset: 0x00000100
Usage: repack-MTK.pl <COMMAND ...> <outfile>
Repacks MediaTek boot, recovery or logo images
COMMANDs for boot or recovery images are:
-boot [--debug] <kernel> <ramdisk-directory>
Repacks boot image
-recovery [--debug] <kernel> <ramdisk-directory>
Repacks recovery image
(optional argument '--debug' can additionally be used to provide useful
information for debugging purposes, while repacking)
COMMANDs for logo images are:
-logo [--no_compression] <logo-directory>
Repacks logo image
(optional argument '--no_compression' can be used to repack logo images
without compression)
- Note: for the new platforms requirements, repack script now takes into account the file (created when unpacking) containing extra arguments. More information about the built image is now also displayed (example shown bellow).
Build information (example):
