[TOOLS][HOW-TO] One Click Scripts to Pack/Unpack boot.img

This is for all ROM cooks, Kernel devs or anyone who wants to make quick changes to the Kernel or ramdisk without wasting much time!
I made or rather put together some scripts for-
All this happens in just one click
Unpack boot.img
Repack boot.img
Make CWM flashable signed zip
Its very easy to use. Download the tools (At the end of the post)
Extract them..
In the root of the extracted files place the boot.img you wanna mod.
Then,
To unpack the Kernel-
Code:
./extract.sh
Your zImage will be in kernel/zImage
Your ramdisk will be in ramdisk folder (unpacked)
Make the necessary changes.. whatever you wish.
Then to pack up everything and get output as boot.img , run.
Code:
./pack_boot.sh
Your repacked boot.img will be in out/boot.img
OR.
If you want a CWM Flashable zip,
Code:
./pack_cwm.sh
The flashable zip will be out/GT-I9103_KERNEL.zip
Easy eh? :laugh:
DOWNLOAD
On a side note,
What in contains:
My scripts
mkbootimg, unpackbootimg and mkbootfs binaries (Compiled from latest CM Source)
signapk.jar and necessary files (To Sign Zip file)

Thanx a bunch for this. I have boot image of a stock gb kernel and want to just add voodoo sound and increase the max brightness level a bit. Is that possible using this tool?
Thanx!!

Then make changes in Kernel source,
Compile , simply replace the compiled zImage with the one in kernel/zImage .. and run ./pack_cwm.sh

You can use it for your fit too. Simply change base address. Or may even work as it is. Password for zip is galaxyrrocks

Would this work on galaxy note n7000 stock kernels if zImage were renamed to boot.img?

For N7000 you can use these tools since its a zImage Kernel and not kernel+ramdisk like GalaxyR.

NO buddy it wont.

It works if it uses the same boot.img format (I mean there are e.g. Sony devices that has some different kernel image structure.).

My friend has it buddy bt its like samsung grand splash in water. Also about the kernel, if u said then i will test it in my friend's mobile. Will it brick it if wont load that kernel??

Buddy, just check if you can unpack and repack. No need to load it on to the device. Faulty kernel can really brick the device.

[Q] Linking sd-ext/dalvik-cache to /data/dalvik-cache error in m2sd

Hi, can someone help me please. M2SD cannot link sd-ext/dalvik cache to data/dalvik-cache. What seems to be the problem?
Specs:
HTC Explorer
JaggyRom4.1

Probably no space in /data
Use diskusage app to determine whether you have enough space.
There should be log in /data /m2sd...
Post it here.
If you're using mount2SD app, enable debug in app and post log screenshots Good bye :thumbup:
Sent from my HTC Explorer A310e using xda app-developers app

Mention what ROM are you using? And check if its supports memory script.. i.e. busybox & init.d??
And in case, it doesn't support then you cannot use any mem script...
So, tell what ROM it is. Then we may find the actual reason... and then the solution..
Press THANKS if it helped!!:good:

Sorry for the late reply.. but I think jaggy Rom already has a mount2SD script.. so you may not be able to use mount2SD again
After fresh install, delete all file's in /etc /init.d.. and then install mount2SD. May help
Also simple wiping cache and dalvik cache from recovery will help

I think just flashing the m2sd(no config needed ) solve the problem because it clears all other scripts before it setting the memory script

Init.d are scripts that can run on boot. You can create your own Init.d script also. There are several tutorials on xda for that search it. And to use it first you muse check whether Init.d is enabled in your rom
To check that use universal Init.d enabler app from playstore and check it if it is not enabled enable it using the same app

The last time i used a supercharger script it used init.d for some functions. So probably you want to have init.d enabled. If i'm right some functions were also wrapped in a service so if you don't have init.d you could install the service to gain some functionality.

here is the boot extracted folder
which is having the ramdisk folder in sbin
you have to covert that folder into ramdisk.cpio
and if you have any other xperia L kk kernel compare the permissions of that cpio file with them.i guess the permissions also effect the booting
also i can provide you the files i edited if you can somewhat replace them directly inside the cpio without extracting it? :\
becuase the permissions are the main issue i am getting :\
EDIT:
Here are the files i have edited basically
init.rc and init.environ.rc
if you find it easier you can also replace both the files in any kk kernel
http://d-h.st/m6ix
http://d-h.st/Tb0j
see whatever suits you better or is easier for you
thankyou

inside the ramdisk folder most probably
though i have very less knowledge about source building
but it should be present in the ramdisk/sbin/ramdisk.cpio
here will be the 2 files
edit them then build the .cpio and then build the kernel

well you din't pack it correctly
firstly ramdisk.cpio need not contain sbin and other folders
it should only have ramdisk folder contents
and the ramdisk folder directory should also not be present
see the image attached
ramdisk.cpio should just have the contents of ramdisk folder only
not even the directory
so that as soon we open the cpio file
we get all that is shown in image
the link i gave you move inside sbin/ramdisk/
now pack all the content present here in ramdisk.cpio not the rest
just use that ramdisk folder
here use this link
extract it and it will contain just the ramdisk folder
now put the files in the ramdisk folder in cpio file
