What commands are you using
The following command will do it for you
Code:
find .|cpio --quiet -H newc -o|gzip -9 -c - > ../initrd.gz
here is original initrd.gz from ROM and image that i want to put inside:
black.volyn.net/or.zip
here is the file i'm getting after command:
black.volyn.net/initrd.gz
(add http to links, i can't post links yet)
Image is changed, but the phone reboots when bootanimation must to start.
Can someone to pack me initrd.gz with image from archieve?
Try the link below
http://dl.dropbox.com/u/26430630/initrd.gz
Hopefully that will work for you
Thanks, works fine!
Which version of Linux did you use to make inird.gz?

ketut.kumajaya, is it possible to resize Data,System and Cache on Ace? Maybe something like this...?
For example, the size of the partition of Indian (S5830DDKQ5) firmware are different (+1Mb to system and cache) from those that have been in all previous firmwares (KPN, KPH...).

Under Windows you can use JDK + Cygwin Custom Package + dsixda kitchen. Head to dsixda kitchen thread for more info. It's built for HTC but usable for Galaxy Ace / Mini (unpack / repack boot.img)
iv tried to us JDK + Cygwin but once I build the boot.img and flash it my boot animations stop working dose anyone no why ?

Good point to ask, can I do this with normal boot.img or I really need boot.img from nandroid backup??
I've put together a tool undoing what mkbootimg does. There are other tools splitting a boot image into the
kernel and root file system, but I didn't find any extracting the command line and base addresses, so I wrote this one.
It handles plain boot images as well as boot images embedded in larger filer, e.g. update-images.
Code:
$ unmkbootimg boot.img

When I attempt to compile kernel from source, Sony said in the read me file that memory layout and other stuff are passed to kernel via cmdline. I do that just like it's written in the cmdline I quoted?! because I want to use the latest kernel source with an existing zRam but i'm unable to make the newly compiled kernel to boot because I am unable to pass arguments via cmdline on boot :crying:

It's because it's not an Android boot image, but a Rockchip specific kernel image file.

Why? It's a trivial hack, and if you're a programmer, you'll put one together in minutes anyway.
So, no.
That is very bad and unethical. It is not a question of I or somebody can do it. Even it violates many things by saying no. What a pathetic situation.

I'm saying that you are using Foss as you like and hesitating to publish even a trivial change that you made. How can the community trust your binaries unless they don't have the source. What kind of mindset is that? Have you ever read GPL?

You, my friend, are making a fool of your self. Please, don't let me hinder you.
I am trying to spread the awareness against the closed source behaviour and I hope I achieved that in whatever miniscule way.
I don't care about your binary or code but thought of asking you to know if you are intentionally not giving the source by giving just the 32bit binaries. Anyway so now everyone knows...

I can provide the steps to do this in Linux as that is what I'm familiar with.
The system.img file is a sparse ext4 image that needs to be unpacked before it can be mounted. This is done with a binary compiled from AOSP source. Here are the steps for that:
Code:
git clone https://android.googlesource.com/platform/system/core
cd core
git checkout android-4.2.1_r1
cd libsparse
gcc -o simg2img -Iinclude -lz simg2img.c sparse_crc32.c backed_block.c output_file.c sparse.c sparse_err.c sparse_read.c
Once the simg2img binary is compiled you can make use of it on a sparse image:
Code:
simg2img system.img system.unpacked.img
The resulting unpacked.img will be much larger than the sparse image but can now be mounted and it's contents traversed.
Code:
mount -t ext4 -o loop system.unpacked.img /mnt/unpacked_system

kernel sources for Xperia SP (C5302, C5303, C5306, M35h) {FW: 12.0.A.1.257} are available...
link to download sources:
http://dl-developer.sonymobile.com/code/copylefts/12.0.A.1.257.tar.bz2
i will keep pushing stock kernel sources to my git tree at the following branch:
https://github.com/DooMLoRD/android_kernel_sony_msm8960t/tree/sony_sources
following are the build instructions for developers who plan to work on this device....
toolchain recommended: Google GCC 4.7
Building kernel (zImage):
for Xperia SP:
import defconfig
Code:
ARCH=arm CROSS_COMPILE=~/arm-linux-androideabi-4.7/bin/arm-linux-androideabi- make viskan_huashan_defconfig
build zImage
Code:
ARCH=arm CROSS_COMPILE=~/arm-linux-androideabi-4.7/bin/arm-linux-androideabi- make -j8
incase u get errors like:
Code:
error : /scripts/gcc-wrapper.py
just correct the permissions of that file
Code:
chmod 755 ./scripts/gcc-wrapper.py
here is patch for compatibility with GCC 4.7 compilation

DooMLoRD
Instructions for building kernel.elf
first get the kernel built... once kernel is built u will get zImage and copy that zImage to the folder containing the build tools...
i have posted the build tools i use here:
https://github.com/DooMLoRD/build_tools/tree/master/msm8960t_viskan
Sony using the ELF format (similar to the 2012 devices)...
build kernel.elf
u can directly use the files posted at my git repo for build tools
or
use the following command:
Code:
python mkelf.py -o kernel.elf [email protected] [email protected],ramdisk [email protected],rpm [email protected],cmdline
the correct RPM.bin & bootcmd are posted at my git tree for build tools...

Hi Doomlord.
Being a fresh Xperia User, never heard about u on HTC forums. But glad to know you are helping a lot of people around here. I was wondering whether you could help me in understanding a bit about xperia phones before i dive into kernel kanging n stuff.
What i know from HTC devices
Partitions are like this:
Boot (separate partition on NAND)
Recovery (separate partition on NAND)
System like above
Data, same
Cache, same
etc
There, we used to flash boot.img to boot. boot.img contained kernel zImage+ramdisk
For recovery, we have recovery.img which contained zImage+recoveryramdisk
Then system and data etc as every other phone.
Here in Xperia, i cant understand where the recovery is. Is it inside kernel.elf?
Is it placed on a dedicated partition?
I want to know what i am messing with, before continuing.
What i plan to do is.
Build a clean TWRP from source (for myself, usage and learning.)
Build a stock based kernel from source. Add few govs/scheds and maybe Doubletap2wake etc. (but thats a little way ahead.)
Can you help me with this?

one more thing, if i build a custom kernel (lets say, stock-based), without any major changes..... can i flash that kernel file without unlocking bootloader???
as i understand, only kernel ftf files can be flashed via flashtool in locked bootlaoder.... correct me if im wrong.

About Xperia SP(m35t)
Hello DooMLoRD
I want to ask you about how to build a kernel of m35t. I had tried to use the build_tools-master to unzip the kernel of m35t, and then repacked it without any modification. I flash the new kernel.elf but the phone doesn't work, how should I do ?
I want let the m35t run on Android 4.3 cause Sony hasn't update it, hope you can help me. Thanks a lot!

Thanks, Pec0ra.
Yes, I know the command is changed, I repacked original kernel with build_it_JB-4.1.sh, the system is 12.0.C.2.58, everything is original, but the phone doesn't work.
I guess there is a little difference between c5303 and m35t, that I need to make a little modification to this tool.
I found the difference between m35t and other SPs
Finally, I found a difference between m35t and other SPs. The build_tools-master shouldn't be wrong, there is only one explanation is the RPM.bin not working for m35t. So,the rebuilt kernel can't boot up the m35t. @DooMLoRD, could you give me the right RPM.bin for m35t? Thanks a lot!

I think you can simply unpack it from stock kernel with the build tools. You will just have to find out which one of the extracted file it is since it might have another name.
Good news!
Good news! I found the way to extract rpm.bin witch use the flashtool. I use the version 207 C5303's zimage and ramdisk.cpio.gz and m35t's rpm.bin to repack the kernel. When I flash the kernel and version 207's rom in my m35t, it works! But only press the power button can let the back light gets on and off, the screen still can't display anything, and it can't play any sound, but it still take a big step!
