[DEV][TOOL] kernel.sin unpacker {UPDATED for Z1 and above!}

DooMLoRD · Sep 15, 2011

THIS IS FOR ADVANCED/EXPERIENCED USERS ONLY

[ info ]

hello devs/users this should be a useful tool (its just a small perl script) for u guys... i have modified the popular unpack-bootimg.pl script to support the (new) kernel.sin files... so it will basically unpack kernel.sin to zImage and ramdisk, ramdisk will also be extracted...

[ requirements ]

linux machine
perl

[ supported devices ]

Xperia X10 (GB update, custom kernels for unlocked bootloaders)
Xperia 2011, 2012, 2013 H1 devices
Xperia 2013 H2 devices onwards with dt.img extraction support

[ download link ]

unpack-kernelsin.pl

[ usage ]

Code:

./unpack-kernelsin.pl kernel.sin

Enjoy!

Use Ubuntu or back|track 5 r1 which is what I am using right now also it has flash player plugin pre installed unlike ubuntu 11.04. Also as lons as you know a bit about security penetration then bt5r1 is the best linux distro

aZuZu u are the expert at porting linux stuff to windows

Wouldn't perl work on Windows too? split_bootimg.pl works fine on both Windows and Linux...

Also, are you sure 1F 8B is enough? Because I see a lot of 1F 8B in kernel.sin, while 1F 8B 08 is the kernel magic for SE devices.

well it should as long as u have the required binaries in place

1F 8B has been enough for Xperia X10, Arc, Neo, Play, Mini, Mini Pro, Ray (as i have made insecure kernels for all those devices using this same file)

I remember seeing a lot of 1F 8B strings through X8 images, so you maybe want to add support for them by adding 08 and you won't break support for already supported ones.

Little correction here ;-)
1F8B08 is the tar.gz magic number and has nothing to do with SE

But you are right its safer to search for the whole magic.

safer and proper way - parse SIN header, extract payload, parse ELF header in payload, extract program tables.

everything other, like signature search and heuristic analyze, can work, but can fail

can u kindly post the hex delimiters for those parts/sections?

may be u can provide us with the tool to unpack kernel.sin, since u posted the tool to make a custom one
