What u need
windows or linux
ROM (that u wanna port to ace )
Dev Tools (like pack/unpack boot.img) Like this for windows and or linux
What u need to do??
unpack your boot.img
Change file on ramdisk
init.rc need to change >> (unpack the boot img from rom u wanna port
open init.rc and copy the stuff after BOOTPATH
change ramdisk/lib/modules >>> your modules ( not really importatnt )
repack ramdisk boot.img

have you tried to port a kernel before? this guide doesn't mention about some spesific important stuff. it will definetely brick our device.
cool
a cool guide. find as pdf attached
this is only an example. our kernel partition is only 5mb. any size bigger wont work. then how about initbcrm2153 file?the zImage file? i've made two kernel. its difficult. port a kernel is more difficult and definetely not as easy as described in this post.

porting is too easy
if you have any doubts just check the attached file ! !
he also provided with SS ........
we can easily port it into our deveice
then...prove it. try to port a kernel from mini.
you also forgot this part. whithout this part our device won't work
===============================
then add/replace these in the rom it self ( copy from stock or cm7 )
These are Always needed !!
/lib/libril.so
/lib/libsecril-client.so
/lib/libsec-ril.so
/lib/libdiag.so
/system/hw
/system/modules
/system/etc/firmware , ppp, security, wifi, permission vold.stab
/system/user/keychars, keylayout
========================
one problem also comes from our recovery mode. unfortunately in our device it was stored inside kernel while in other device it was stored in different place.
It can Brick our Device
First Check it is Working and Then Post
thx for it i will try it
i dont think its that easy.. if it would hav been then we would hav had a kernel long back!!

if porting means use kernel binary from one device to other device, not only not easy, but near to impossible. unlike pc which architecture is standardized, every cellphone have their own architecture make it impossible create generic kernel like you find in linux distro. you change hardware, it does't work. you mix with module from different version, it does't work. you mix with module from different compiler version, it does't work.
if porting means source code modification, that could be work, but need a lot of work. if someone ask how hard, last time i write my patch, i need about 6 hour just to add 2 lines modification in kernel source. i use linux in last 9 years and in real life i am a programmer, so reading c source code is something that i do almost everyday. still, i need that 6 hour because linux kernel source code is very complex.
and why op give this thread's title kernel. the tutorial is about using rom from other device using your original kernel.

thank you. i just wanna post the same thing before saw your post, and you're right indeed. theres no such thing as "porting kernel". binary kernel is specific, it'll only work with the device it were originally compiled for.
ROFL.....
BTW dont post tutorials , ports, etc that are somewhat copy paste and not tested it yourself..
Hey what about drivers... I wanted to get usb otg drivers on galaxy ace plus... Some dev ported it from galaxy s2 to galaxy s... But i dont have much knoladge of kernel development as i have windows... And i also found few lines about otg in my volt.fstab
# otg sdcard
{
ums_path = /dev/zero
asec = disable
}
usb_mount sdcard2 /mnt/sdcard/usbStorage auto /devices/platform/msm_hsusb_host.0
#end line ## keep this line
So i think it can support usb otg but doesnot have drivers...
Can any one help....or suggest something...

Hey
Is Flashing from update.zip the new trend ?
'Don't know but here is how you can do it quite easily using this template.
If you target a GT-I9000 on Eclair, you'll need to customize one thing :
In build-update-zip.sh, set DROID_HOME to the source code path for your local Android repository.
If you target another Galaxy S phone or another version of Android, you'll need to adjust ro.hardware and ro.build.id properties accordingly.
This template is done for Linux/Unixes/OSX.
If Linux cost too much for you or your employer, please contribute by sending a .bat equivalent to the .sh
Of course, you also need to put a valid zImage to replace the template's empty zImage
Feel free to adjust to your needs. License is WTFPL
Note : requirement are Java and Android source repo, already build.
Looks awesome!
I have a question though... why do you need to flash the kernel in an update.zip at boot?
As far as I know, the system will read the kernel at boot up time and load it into ram. It won't access the on-disk file again until the next boot. If that is true, then flashing while running should be 100% safe, right?
RyanZA it's an update.zip, not a ramdisk.
The point is getting an easy flashing method, requiring no computer.
And you don't even need to root your phone !
curio, as i see this script is quite simple, so dont u think this all could actually be done on the phone directly? i mean if people cant afford a linux machine...
edit:
sorry for major dumbness, but do you think this could also somehow be used to reflash a nandroid backup?

I don't think the signing tool works on android -- maybe it does? Anyway editing scripts on a phone seems a bit silly!

Nope actually this is not dumb at all
Yes the flashing part run in updater-script can be started manually.
In the script :
Code:
"redbend_ua", "restore", "zImage", "/dev/block/bml7"
The update.zip presented here mainly targets custom kernel creators in order to give them another way to distribute their work.
This is a working example of how to use redbend_ua programmatically, hopefully it may help new ideas coming. redbend_ua usage is not limited at all to kernel flashing.
PS : you can use this template with windows as well, you'll just need to translate the ulta-basic .sh to a .bat script, or do the signing part manually.

quick question, the build-update-zip.sh is not a must if i only want to flash zImage, rite?
looks like that, I need to modify updater-script (if needed), as well as putting a zImage into ur zip file, and finally remove the build-update-zip.sh from ur zip attached
then, ur zip file can be used for flashing
is it correct?
thx
So this will let people flash any rom from an update.zip (once the ROM makers take this into account) via RomManager without ever having to use Odin to get off stock?
Awesome!
Thanks for the update script curio! this looks great.
One quick question - ive noticed several update.zip scripts for the galaxy S
have update-binary included.
Does anyone know what that does?? where did you get yours?
ive had success in using update.zips without that file at all.
Could anyone post information on what that binary is/does?

Thats for the updater-script i believe. In most cases, theres a update-script in the zip's as well and the recovery picks that up in which case it doesn't need the binary and hence works.
Okay !

When you run ./build-update-zip.sh,
- it produce a temp zip file containing appropriate files in it.
- then there'is the signature part, building another .zip, ready to be used.
- this "final" update.zip is put in the same current directory and you can use it as it is.
No further complication

Yes, to flash a complete ROM (several partitions) one more thing is needed.
On command line, redbend_ua accept only one command.
In order to run several commands successively (ie flash multiple partition like Odin does), you'll need to write them in a file.
The file /cache/ota/command should do the trick, but it's untested right now.
There may be other method to prevent rebooting after flashing (hacking the redbend_ua binary, finding the appropriate command line option or removing the reboot command temporary)

Right, many update.zip done today are made without knowing anything about how it really works
I studied a bit before creating mine, here is a walk-through this fairly undocumented process :
- recovery mounts /sdcard/
- recovery search for a default file named : META-INF/com/google/android/update-binary in the zip and runs it : see the source in bootable/recovery/install.c
- update-binary is actually updater in sources
- updater looks into the zip file to the script file named updater-script, update-script is obsolete
- updater then runs the commands listed in updater-script : here is the list of commands.
- then reboot
The only documentation I know for this command is the recovery/updater/install.c file itself

many thx for ur detailed explanation, supercurio!
Thanks curio,
very helpful explanation!
Thanks supercurio for the template!
However, there is no need to spend many hours (depending on hardware and bandwidth) pulling down 100s of megabytes of source and compiling it all if all you want is to sign an update.zip with test keys (if you already have the zImage)!
Just google around for "signapk.jar test keys" and you will get there.
BTW: I know that koush, leshak and wesgamer have Samsung Galaxy S trees up at Github but are they fully merged with AOSP yet?
I'm planning to go build my own kernel for this beast to try to solve the mono FM radio mystery, but last time I checked around it was said that the SGS tree required the use of a custom toolchain to get it to work at all.
Any comments on this?
Hey miki4242 !
Good to know that signapk.jar doesn't require hundred of megs of dependencies
About toolchain, you can use the one indicated by Samsung (CodeSourcery) but you'll face the big and ugly WakeLag.
I recommend you crosstool-ng or buildroot to build toolchains, with gcc 4.3.x march=arm mcpu=cortex-a8 mtune=cortex-a8 (no 4.4.x with march=armv7-v)
The building tutorial will be a part of the documentation I'll publish with my lagfix opensource release
Right now these info are too hard to find.
PS : I send you a mail with attached .config for ct-ng !

Sorry for my ignorance, but does this mean someone can package Froyo in an update.zip and we could update it directly on our phone without needing Samsung Kies or Odin?
@supercurio:
Thanks for this well working template.
In updater-script:
Code:
line 17: package_extract_dir("zImage", "zImage");
should be
Code:
package_extract_file("zImage", "zImage");
But it did work with package_extract_dir, for some reason, too.
Btw, could you send me the config for ct-ng ?
I'm also struggling with this wakelag.
1. Usage
./editor.sh [place where the kernel is] [ place where your ramdisk is]
### you must let editor.sh know where your cross compiler is.
open "editor.sh" and edit COMPILER
2. Example
./editor.sh /home/zero/Desktop/test/zImage /home/zero/Desktop/test/my_initramfs.cpio
3. Info
- can not use an initramfs which is bigger than the stock initramfs.cpio's size
>> for instance, stock JM8's got an "initramfs.cpio" which is 3.4MB.
you can use reasonably bigger initramfs by gzipping the initramfs.cpio ->> initramfs.cpio.gz
this process reduces the initramfs.cpio's size but still can't use if initramfs.cpio.gz is bigger than 3.4MB
(this means that if a kernel already has gzipped initramfs, it is difficult to make it. you may want to remove something in order to have more room.)
- you can choose either your_initramfs.cpio or your_initramfs.cpio.gz
(this script compresses the ***.cpio if this is bigger than the stock.)

Sweet! Awesome work.
Any reason you now have TWO threads about this subject ? (Or: why not edit / add to your other thread about this ?)
Also, I have a toolset to do all this on Windoze without Linux and compilers... I used it to build the JPH root, but haven't tested it on enough kernels yet to consider it stable and publicly release it.
Hi,
I have tried these scripts on i9000WXJPA and '070701' is found 60 times and 'TRAILER!!!' is found 2 times! I find it a bit risky to assume that the first match is the right one!! z4ziggy's script doesn't even contain the -m 1 so I guess he believes there will always just be one entry!! There must be a safer way to extract initramfs from a zImage. Doesn't the header contain the exact entries where to find the partitions?
Thanks
JKay
Great script, thanks.
I'm trying to port this for use with the Galaxy 3.. uses s5p6442 processor.
Any idea what the mcpu and other flags/values would be when it's rebuilding the image?
Thanks
The eclair kernel compilation comes up with
-D__LINUX_ARM_ARCH__=6 -march=armv6k -mtune=arm1136j-s

apparently s5p6442 is s5p6440's poorer cousin (the latter has at least a better CPU, arm1176jzf-s), but there's no information to be found on Samsung's website about it
good luck in making it boot and please share if you make it work, I didn't manage to get it working yet (I'm using z4mod and so far it's generating an invalid zImage)

Anyone mind to explain what the "compiling" is doing in a few words? It seems start and end are not changeable anyway.. checksums maybe? wild guess. Just curious. It works fine anyway.
Hi there.
First: Im a noob, so unless i have fewer than 10 posts i can only post in general forum - otherwise i would post on an existing thread (i will mention later).
Last week i got a new phone: Samsung Galaxy Y Pro (GT-B5510).
Its a nice phone, but im missing a thing: a firewall.
I tried droidwall and other, but they arnt working. So there is something wrong with the netfilter/iptables modul and ive to rebuild the kernel.
After a quick search i found this thread and this post.
I already set up a Ubuntu (10.04.4), downloaded the source from samsung and the toolchain from Sourcery (like they mention inthe infofile from samsung).
I build the kernel, like irfanbagus in his post, but for my device.
I got lots of compilerwarnings, but in the end i have had my zImage without errors.
I split my boot.img, which i got from my device with Terminal Emulator, with split_bootimg.pl.
Now ive got a kernelimage and a initrd and ive to put them together.
Presumably with mkbootimg, but ive to know the baseadress.
I tried the offset from the thread mentiond above.
I made a tar and flashed it with Odin1.85 and half bricked it.
[I only can see a grey battery on the diplay and if i reboot it it stuck on bott/splashscreen]
Maybe somebody can help. (please)
Is the problem the compiled kernel, due to the warnings?
Or is it the wrong baseaddress? Well i could not find the address inside the sourcecode (like kconfig), like i read somewhere, thats why i tried the one from s5360.
There is no problem with odin or the cable, cause i can flash my backup with it to 'unbrick' it.
And why is the bootimg around 700kb smaller than the original?
Thanks a lot in advance.

upload your boot.img
boot.img
Here it is.
boot.tar = compiled
boot-stock.tar = original from my device
Size is not problem as long running well.
In my sgy always fail when size >
5.5mb
For boot-stock.tar u get from dd or pda stock-rom ??
Mmm i thing irfan has answer so ur save dude.
its dd.
i don't find any problem with boot.img. offset is equal (0x81600000). the problem maybe in your zImage. make sure you build with correct defconfig. mine is bcm21553_totoro_05_defconfig, i don't know yours, see in text info inside zip file from samsung. and make sure using the same compiler version with text info said. using different version make prebuild kernel module inside initramfs not working. start with default config from xxx_defconfig just to make sure your step is correct. and if still not working your best hope is build your module as loadable module (.ko), add init.d support in init.rc (inside initramfs), and load your module using init.d script.
about the size, it's nomal boot.img from dd command bigger than normal boot.img because it's copy whole partition and include unused bytes behind the original boot.img.
hm, ok.
thank you irfan.
i followed the instructions from the txt inside the archive:
"bcm21553_luisa_03_defconfig" with "g++ 2009q3-68 arm eabi"
ill try again.
my bad. i download wrong files, and end up with comparing the same original boot.img
your compiled boot.img don't have md5 checksum. i am not sure it have effect, i make that tutorial based post from harish2704 here. mkbootimg from harish2704 have --kernelMD5 param. try use that one.

our kernel partition only 5 mb my friend...
Boot.img from dd not work with me so i pick from pda stock-rom
(i use from doky thread).
Mmm that why i fail when boot.img more than 5mb.
Trying other method to compile, irfan say merruk use lzma or someting like that.
I can only suggest the method irfanbagus described (loadable kernel modules) because the source code Samsung released probably isn't up to date. The benefits of compiling the needed modules into the kernel are too little compared with possible bugs which are in the released code but not in the stock kernel.

After a weekend full of trouble, today i found time to continue the bootimg-thing.
I now compiled only the modules and load them now with initd, because i was unable to build a runnable kernel from source.

This is my first time working with Android kernels, but I compiled the 2.12.40 kernel source adding in support for KVM ( Kernel supported Virtual Machines, ie running Windows almost full speed ) and Bridge ( to allow qemu-kvm to set up network adapters bridged with the current wifi adapter ).
I tar'd the bzImage & modules, but don't know what to do to make something installable/flashable so will need help on that end of things.
Edit:
I uploaded a new flashable kernel img based off 2.19. This one should support: kvm, bridge and NTFS read/ *LIMITED* write, swap and ignore kernel module signatures. XDA only allows 8mb for .img files, so I tar'd it.
Edit2:
I compiled a ZE550 kernel ( called hd ) and if some brave souls want to try it, I also put together a boot.img.
Edit3:
New fhd kernel has been compiled with additional usb modules. Kernel should now load kvm related modules automatically, so you shouldn't need to use the script anymore.
Anyone brave/crazy enough to try it out? I'm guessing you need an unlocked bootloader & root.
Edit 4:
New fhd & hd kernels for 2.20
Edit 5:
New exfat.ko module

This is my first time working with Android kernels, but I compiled the 2.12.40 kernel source adding in support for KVM ( Kernel supported Virtual Machines, ie running Windows almost full speed ) and Bridge ( to allow qemu-kvm to set up network adapters bridged with the current wifi adapter ).

Why 2.12? 2.18 kernel source is available...
That just happened to be the kernel source linked in Android development. If this test works out, I can probably do the same thing with whichever kernel source is available.
Our phones are pretty amazing to be able to compile their own kernels natively on the device.
Sent from my ASUS_Z00AD using XDA Free mobile app
Finally able to compile the 2.18 kernel.. it's a bit weird since it acted like it was missing some files. Untar'd the 2.18 kernel source over 2.12's kernel source and that allowed it compile.
Anyway, it's in the OP called fhd_kernel_20150629.tar and should have KVM ( kernel supported virtualization ), Bridge ( for Qemu-KVM to create bridging ethernet adapters ) & NTFS Read/ *LIMITED* Write.
Once again, it's in the form of bzImage and the modules since I don't know how to replace the kernel on Android devices. ( normally, I'd just make a test linux line in the boot menu for Linux )
One suggestion would be to flash the zImage using
Code:
fastboot flash zImage nameofzImage
or test it using
Code:
fastboot boot nameofzImage
but I dont know if the phone supports the "boot" command.
I´m not sure about the modules either and I can´t test it, as my phone didn´t arrive yet.
Other solution, try this:

Can I ask how you included NTFS r/w support into your kernel? Did you just set the CONFIG_NTFS_FS flag?

I added CONFIG_NTFS_FS=m ( you could set to that y ) and CONFIG_NTFS_RW=y in /{working directory}/device/asus/moorefield/fhd/mofd_fhd_diffconfig
when you make the kernel, it's going to ***** about the config files not matching; follow the directions and manually update all of the other config files and it will finally compile.
Building for Android is a pita. )
Well, then here come the disappointing news (I discovered that when I wanted to include NTFS USB-OTG support directly by the kernel for my TWRP and it didn't mount it as R/W):
CONFIG_NTFS_RW is just a partial write support. It won't create files or folders, it can only overwrite existing files and only by the size they currently have
config NTFS_RW
bool "NTFS write support"
This enables the partial, but safe, write support in the NTFS driver. The only supported operation is overwriting existing files, without changing the file length. No file or directory creation, deletion or renaming is possible. Note only non-resident files can be written to so you may find that some very small files (<500 bytes or so) cannot be written to.

Only possibility available is to include ntfs-3g driver using fuse
Yeah, that is a bit of a downer. Now to figure out why nobody finished the NTFS kernel module.

Please keep me posted, I'd like to remove the dependency of ntfs-3g in recovery. I fear there actually is no native support of NTFS (googling was not helpful unfortunately)
1) modify module loading function to ignore module version/magic strings.
2) compile the kernel with toolchain used by ASUS (or close to it)
3) use pre-compiled tntfs.ko from original boot.img
I don't have right now the patch for module loading procedure. Need to check old Galaxy S3/S4 custom kernels source (but it's should be easy to patch by finding error string). In time when exFat module source wasn't available, this trick was very common in samsung custom kernels for exFat support.
Thanks
Wait wait wait. Did I read that correctly? Full speed windows? On the zenfone? I think I just died. Does this mean windows 8/10 or windows xp and below?
I know a bit about android kernel, and i'm thinking about buying this device. Well, i'm going to try to build a kernel for this device as soon as i got this device. One thing you should know is, android is an open-source, so before you uploading your compiled kernel, make sure you have already uploaded the sources

It's only in theory.
In reality, there is no Z35xx support in windows, and i doubt anyone will write drivers by himself (windows isn't opensource). Officially Z35xx is Android-only SoC.

The source is already available, so no worries there, since this is source that Asus released.
For all of the brave folks out there, I was finally able to create a bootable image of the latest 2.19.20 kernel. Anyone brave enough can find it in the OP.
I flashed it and my phone booted up, so that's a bonus.

is there extra features such as other governor or i/o scheduler?

To be honest? I can't remember since my main focus was getting kvm compiled in.
I've attached my .config for the 20150707 build ( in the boot image ).
I've also attached a screenshot of Windoze 7 being installed.
Commandline for Arch Linux x86_64 to start qemu-kvm to install windoze:
qemu-system-x86_64 -display none -vnc :1,password -monitor stdio -m 1G -smp 4 -enable-kvm -drive file=/mnt/0/machine1.img,format=raw -cpu host -cdrom /mnt/MicroSD/Vcd/en_windows_7.iso -boot menu=on --usbdevice tablet
breakdown of the command line:
-display none = no display, I did this to test the virtual machine. normally, you would probably use -display sdl w/ XServer-XSDL running
-vnc :1,password, This says to set up a vnc server with normal port + 1 ( 5901 ) and you expect a password to be set later
-m 1G, 1 gig of ram
-smp 4, our VM will use 4 cores
-enable-kvm, enable Kernel support Virtual Machines
-drive file=/mnt/0/machine1.img,format=raw, my "disk" file
-cpu host, use the same cpu information
-cdrom /mnt/MicroSD/Vcd/en_windows_7.iso, my Windows 7 install cd turned into an iso
-boot menu=on, enable the boot menu ( hit F12, etc.. )
--usbdevice tablet, Qemu's Vnc server sucks at tracking mouse positions so using tablet mode keeps the mouse pointer .. well on-point
Tks for share
Kernel great work
But how to install window 7 ? ?

Hey xdas,
i just received my new Samsung Galaxy z Fold 4
SAOMC_SM-F936B_OXM_EUX_12_0045 EUX /-/EUX/EUX
Kernel : 5.10.81-afaneh92-gd8d6af751972 (flashed for twrp)
I would like to install nethunter on the device with a working kernel
I tired my best to understand the docu on kali but its not the best
i am also new to compiling kernels at that level so maybe someone can help here
I attached as much as i could
So the steps i took so far is
Unlocked Bootloader
installed the twrp ( like descriped here : https://forum.xda-developers.com/t/recovery-unofficial-twrp-for-galaxy-z-fold4-snapdragon.4498743/ )
installed magisk
Then for nethunter
(https://www.kali.org/docs/nethunter/)
i downloaded the kernel source :
https://opensource.samsung.com/uploadSearch?searchValue=SM-F936 (my device is EUX see infos for device above)
downloaded the proper=? toolchain , there is an readme_kernel inside the kernel_source with a link to the toolchain , i am unsure about this
https://opensource.samsung.com/uploadSearch?searchValue=toolchain
there are two options i took the S22(Exynos) file ( hope thats right ?)
now we come to the difficult part :-(
first i tried to compile via the instructions on kali docs
unpack the kernel file i did and there a subfolders so i decided to use the subfolder common as the root mentioned in the docs:
you can begin by cloning our kernel builder to the root of your kernel’s folder, and prepare the environment:
from common folder i did git clone https://gitlab.com/kalilinux/nethunter/build-scripts/kali-nethunter-kernel
cd kali-nethunter-kernel
I did not change the configs as i am new to that so i know there are some exports inside the build config inside the kernel file but i dont know how get them together
./build.sh
S. Setup Environment and download toolchains.
2. Configure & compile kernel from scratch
It found the devconfig so i took it as mentioned in the docs (Select your device’s defconfig, then save and exit to start the building process.)
did not edit the kernel config till jet
and ran into the error attached in the error txt
I would like to understand how i can build the kernel the normal way , without the nethunter tool
and maybe someone could help to make this working with nethunter that would be great !
i want to understand the process and i am willing to help , so i am not asking for a final kernel , more for the way to go in general to also give the community a benefit for the next new kernel we want to port
as mentioned the docs are not the best !
thanks for your time
@yesimxev / @V3rB0se / @afaneh92 need some help here
Which toolchain to you use in nethunter kernel builder? I'd recommend clang-12.
https://android.googlesource.com/platform/prebuilts/clang/host/linux-x86/+archive/refs/tags/android-12.0.0_r12/clang-r416183b1.tar.gz
Download, extract somewhere and add it's path to kali-nethunter-kernel/config (clang-10 is the default). no need for setup environment again.
Any luck with this? i am in the same situation trying to build a nethunter kernel for my zfold4

Great research bro , same as here.
Difference is I am doing it for M21 .
And to flash the kernel I need to do port twrp for vA12 M21 too.
Great respect bro.
Anyone can help with kernel? u need AR9271 and rtl8188EUS drivers on ysl Android 9

Great, I'll add to the setup env script so it won't be missed. It shouldn't happen in the first place though
