------------------------------------------- LGE KDZ Utilities originally Copyright 2013 "IOMonster" (thecubed on XDA and GitHub) Copyright 2016 Elliott Mitchell ------------------------------------------- These two scripts will allow you to extract both KDZ files and DZ files Run unkdz.py or undz.py with the -h option to get more options. -l or --list Lists all files contained in the archive -x or --extract Extract all portions or as chunk-files. See -h or below for more detail. -c or --chunks (undz-only) Extract archive as chunks, unless a specific chunk number is give, all chunks will be extracted. -s ID or --single ID Extract a single slice/partition by ID (can be found with --list). With undz multiple IDs can be given and the whole slice/partition will be extracted -i or --image (undz-only) Extract who archive as a disk image -d DIR or --dir DIR Set directory instead of the default "[kdz|dz]extracted" directory in the current path -f FILE or --file FILE File to operate on A sample workflow can look like: $ unkdz -f H90120j_00_0712.kdz -l [+] KDZ Partition List (format v2) ========================================= 0 : H90120j_00.dz (1***8019978 bytes) 1 : LGUP_c.dll (2875560 bytes) 2 : LGUP_c.dylib (1170000 bytes) $ unkdz -f H90120j_00_0712.kdz -x [+] Extracting all partitions from v2 file!

For this particular device (LG H901), system.image is an EXT4 filesystem. Many tools exist for modifying EXT4 filesystems and these should work fine. The next step would be reconstructing the file. There are three steps, turning the files into chunks, merging them together into a DZ file, and then merging everything back into a KDZ file. The first step has some quirks. "image2chunks.py" currently has 3 strategies for breaking image files into chunks. At of this writing the prefered strategy is to make use of ext2simg from the Android image utilities. This produces results that differ somewhat from LG's images, but is believed to produce sane results. The differences have me wondering whether LG's images are either unsafe, or else relying on special knowledge of the hardware (is the eMMC certain to give back zero blocks for TRIMmed areas?). The next two strategies are utilizing support for SEEK_DATA and SEEK_HOLE, or probing for the presence of holes. Operating System support for SEEK_DATA/SEEK_HOLE is decent, though to my knowledge no versions of Windows include this. This seems a bit of a cheat since it is relying on knowledge of which areas of the image haven't been written to. Probing marks an awful lot of areas as holes, which leaves me uncomfortable believing the results to be sane. As such I reccommend the first if available (ext2simg is known to work for Linux, but I'm unsure Windows binaries are available). WARNING: It has been found there is some additional unknown verification mechanism in LGE's tools. Due to this mechanism currently the generated KDZ files haven't been shown to work. There are some guesses as to where the mechanism is, but as of now not enough is known to work around it. $ image2chunks --ext4 dzextracted/system.image [+] Compressing system.image to
