Nokia N9/950 Compressed Sparse Image (LZO) Writer

sparsify accepts a loopback filesystem image and builds a "sparse image" in the format used by Harmattan rootfs.jffs2 files. The output file can be used as input to fiasco-gen to build flashable FIASCO images. This utility is the exact opposite of ali1234's unlzo.py, and requires the same Python-LZO library in order to run (see link for more info).

Be advised that any attempt to flash images produced using this tool is entirely at your own risk.

Note that the base filename of the input file is written into the output image, so make sure to rename it to the desired value before sparsifying.

Round-tripping an original partition image using unlzo.py and sparsify will produce a different, sometimes larger, output file, as sparsify's zero-region removal logic is different from Nokia's. However, the two files will be semantically equivalent.

Usage: sparsify.py input output
 Example: sparsify.py rootfs rootfs.jffs2

"This utility is the exact opposite of ali1234's unlzo.py" and i am lazy to rewrite :D

Common wook ;) its a small script you can surely do it for everyone :D

Re: [Announce] sparsify - N9/950 Compressed Sparse Image (LZO) Writer
 

lazy
it would require to edit unlzo.py, read it and understand it...and then to write it, that's pretty borring procedure because outcome is not something too special, so...huh :D i am lazy
but, if no one reupload...i will have to...;) :D
so...let's wait little bit longer :D
