Hi Guys,

Sorry for the stupid question... What does this do?

 

[mumbozver]

Thank for great work.

I have request, can You add LZMA compressed zImage support?
Lastest fugumod has LZMA compression, I tried Lestatious 1.8 - Fugumod 2.2 ALPHA 14 from here

If you need something, I could give it to you ... just ask me

Should be doable, at least for the unpacking direction. I'll have a look at it.

I already can extract init files from running kernel, however if they not deleted by later init scripts.
For me more interesting to change init scripts, and put it back to kernel image without compiling kernel myself or ask You to put something in initramfs. Repacking kernel images just more faster.

Done (for unpacking and packing). See post #1. Note that LZMA is slower and thus the script takes longer to complete on lzma kernels.

mizch: I'm getting an error related to the variable at_min

Trying size: 7793816  3896908./repack-zImage.sh: line 284: [: : integer expression expected

At some points it seems to have integers assigned to it, while at other points it seems to have the string "yes" assigned to it.

 

[mizch]

To reproduce the error, can you tell me what kernel you are using it on (download location)?

 

[vishwanathptl]

mizch great work.

but it wont work on my zImage. its froyo kernel (GALAXY FIT s5670).

my zImage is abt 2.0 MB if pulled from mobile and its abt 3.0 MB if extracted from boot.img.

i am confused. i am not getting the rite zImage. plz help me. if u say i wil post both the zimages here. trying from 2 months but not getting anything.

 

[mizch]

I need to be able to reproduce the error here. So please provide a download link to the zImage in question (it's not a problem if it is buried in some .tar for flashing) and I'll look how I can help you.

 

[vishwanathptl]

I am uploading boot.img. I am not able to get zImage.
Plz help me to extract zImage and ramdisk.

Here is my mediafire link to boot.img

[mizch]

Sorry, I cannot extract the zImage for you. This is out of scope for this program and for me. Please ask in a forum which handles your brand of phone how to get at the zImage. When you've extracted it and if the script here doesn't handle it, I'll gladly try to help.

I simply cannot be expected to know where each of those many hardwares around bury their zImage, nor do a Google research on this for any number of them. So I hope you can understand that you're on your own with that.

 

[vishwanathptl]

its k i can understand but wen i tried with HTC Android Kitchen 0.161 - by dsixda, it extracted zImage and ramdisk. but wen i compared my ramdisk with the initramfs of I5700, there wer some files missing in mine. i dont kmow if kitchen extracted the ramdisk completely. Can u help me with this? can u tell me that kitchen extracted the ramdisk completely? Plz..... here is my boot img extracted from my device.The previous one was from firmware files downloaded from samfirmware.com.

Hmm, not working for me:

I always got this error:

./repack-zImage.sh -uv
Warning: there is aready an unpacking directory. If you have files added on
your own there, the repacking result may not reflect the result of the
current unpacking process.
mkdir -p /work/arm/1/zImage_unpacked
cd /work/arm/1/zImage_unpacked

repack-zImage.sh: Can't find a gzip header in file 'zImage'
Terminated


I am using openSUSE 11.2 "Emerald" - Kernel \r (\l).

I tried 2 zImages, one is from

http://derek.theblog.ca/galaxys-i9000m-gingerbread-upgrade
(file: http://www.multiupload.com/N8D9XZ1PIF)

and the speedmod kernel speedmod-kernel-k13e-500hz.tar

Both result the same error.

I tried both V6 and V4 of the script, same thing

Anyone can help?

Hi mizch,
I am getting this error when i am trying to unpack any zImage

repack-zImage.sh: Can't find a gzip header in file 'zImage'
Terminated
(Ubuntu 11.04 x32)

But same kernel i tried to unpack on Ubuntu 10.04/10.10 x64 works perfectly.

So this can't be scripts fault . OS fault possible ?

well, that can be the reason...I got it working on 10.10, and cdesai couldnt get it worked for 11.04...
