This is the kernel module for smb/cifs mount.(windows shares)
You need it for example for this: hxxp://forum.xda-developers.com/showthread.php?t=756158
I didn't found a compatible cifs.ko for samsung s anywhere so I had to compile it.
[recommended] cifs.zip - Eclair(2.1)
[recommended] froyo.zip - Froyo(2.2) - cifs.ko & slow-work.ko (insmod slow-work.ko first)
cifs_froyo_slow_work.zip - Froyo(2.2) - cifs & slow_work in one .ko Do NOT use this because its buggy (slow, reboots when rmmod)
could you pls explain what is this for? Experts needn't, but there're lots of newbies hangin aroud here, like me . Thanks
It's a kind of file system like ext2/3/4, for example.

You have my gratitude
Very usefull! thank you!
i'm back, when i'm trying an insmod i have cifs.ko : invalid module format
i use a jm5 samset 1.9f roms.
I use jm5 (mimocam's fix + root) and I've compiled the module from source-code provided by samsung (opensource.samsung.com) using arm-none-eabi-(Sourcery G++ from codesourcery.com). Maybe samset used something else which is incompatible.

Setenza said he'll add Cifs in the next SamSet release.
can you make one that is compatible with the Vibrant version? Either stock Vibrant kernel or any working kernel compatible.
Greatly appreciated
I've tried the module, but also get the "invalid module format" message.
However, I'm using JM5 + root using kernel 2.6.29 built on Fri Jul 30 15:12:44 KST 2010 armv71 GNU/Linux
Can you tell us for which kernel you've build this module?

I've compiled for kernel 2.6.29.2 using samsung's sources
my phone says he has kernel 2.6.29 [email protected] #1
I'm attaching the module compiled with latest toolchain I could find(binutils-2.20.1, gcc-4.5.1,newlib-1.18.0)

No idea if will work bc I don't have a Vibrant.
In the mean time I've also compiled my own version of the cifs.ko module.
I've used the Samsung sources and used the Sourcery G++ Lite 2010q1-188 for ARM EABI toolchain.
I've only enabled cifs in the kernel config and compiled the module.
I've attached the compiled result.
Thanks for your effort. I'm using JM5 +samset1.9f and couldn't get the cifsmanager to work with all 3 of your cif.ko . I've just dont know why the size the last 2 versions are huge compare to the first one? Thanks anyway. Hope you can come up with something.

thank you very much. It's working on my stock vibrant kernel! YOU ROCK SIR! (using attached vibrant.zip)
Now I can stream all my media files!
(I'm vary curious how you did this, if you can point me to some guides that would be awesome, (I can write some C/C++ code))
Works great for me - had been looking around to see if anybody had compiled the CIFS module for the Galaxy S. I started reading up on how to cross compile kernel modules myself but didn't get very far.
Anyway; I have a slight problem. while mounting and browsing from the terminal as root and through adb as non-root work, I can't seem to browse in any mounted folders actually on the device using either the stock 'My Files' or Astro which was what I was aiming to do.
What I do to mount said:
\\\\192.168.0.0\\Directory /sdcard/smbshare -o user=Username,pass=password,uid=1000,gid=1015
Click to expand...
Click to collapse
Without setting the user and group settings I can't browse unprivileged as everything in the share is 'owned' by root.
I also tried using mount -t smbfs //192.168.0.0/Directory /sdcard/smbshare with the same result.
Anybody else having a similar problem? Maybe it's just something obscure about my setup.

Sorry for the noob questions:
- Can you please give more details on how to enable cifs in the kernel config?
- Is there a specific plate to copy the cifs.ko module?
- Is there a simple (one-click) way to install this?
- is the module dependent on the kernel version? has to be exactly the same?
- is there a easy way to check if it's working (I'm using cifsmanager and get some error saying cannot access device / folder not found -not sure about the exact message text)
Thanks in advance
NOTE: there is no guarantee this will work, because without access to the corresponding kernel source I can't be sure. It may wipe out your device if there's memory corruption! You're warned, use it only at your risk!!
Over the last weekend I wanted to familiarize with the arm assembly, buildsystem, SDK so I created a tun.ko module for kernel running in the JPK ROM. But lots of the time was also wasted trying to guess their config (things like disabled DMABOUNCE and removal of the dummy they added in 2.6.29 from struct net_device, I hope I got it all right).
I encourage to release the kernel source along with the ROM images in the future (it'd be much simpler if there was a git tree that they can just tag with the name of the ROM), and to include the tun device into the modules/tun/tun.c (as in the tarball) so that it is included by default in the future. I won't be doing this process again.
I had to install openvpn with the openvpn installer a second time with openvpn in xbin, busybox in xbin/bb and I created the bb directory and two symlinks from xbin/bb/{ifconfig,route} to xbin/busybox (after mounting /system rw). The DNS to change during VPN must be set by long pressing on the left of the openvpn config slot in the OpenVPN settings GUI.
The tun.ko I keep it in /sdcard/openvpn/tun.ko and the path has to be configured in the openvpn settings advanced settings menu and I choose to load it with insmod.
This JPK rom works great for me, so I'll likely keep using it for a long while now that I've got openvpn running fine.
252ae6e655fa08774f32f67dd76dad3a tun.ko
EDIT: the same tun.ko module works for JPM too
Great job!!!
I use vpnc daily, so I couldn't even think to upgrade to JPK without an available tun module.. now I can!
Would you share your .config, so other devs can use it? Maybe we can hope in a Froyo-voodoo in a short time..
I'm confirming that it works.
Here is how I did it (I garantee that THIS IS NOT THE MOST ELEGANT WAY to make it work)
Install Openvpn from Openvpn Installer
openvpn in /system/xbin
route and ifconfig in /system/bin
At this point, Openvpn could connect and create a tun device, but route are not pushed so it's not very usefull
So, I downloaded this version of Openvpn
http://github.com/downloads/fries/android-external-openvpn/openvpn-static-2.1.1.bz2
As superuser
Code:
su
I remounted in rw /system
Code:
mount -o remount,rw /system
I renamed /system/xbin/openvpn into openvpn_old
Code:
mv /system/xbin/openvpn /system/xbin/openvpn_old
I put that new openvpn binary in /system/xbin
I created symlinks from /system/bin/route and ifconfig to /system/xbin
Code:
ln -s /system/bin/route /system/xbin/route
ln -s /system/bin/ifconfig /system/xbin/ifconfig
I also created a symlink os /system/xbin to /system/xbin/bb, just in case
Code:
ln -s /system/xbin /system/xbin/bb
Here we go

i tried to complie cifs.ko and tun.ko for the JPC kernel and couldnt get it to work. i ultimately went back to eclair because of this so would like to be able to compile modules and other filesystem support.
thanks.

config attached, but the config is not enough and it may not be fully correct (it is enough as far as the data structures used by tun.ko are concerned, I checked them all against the zImage assembly). The diff of the v2.1 image, has to be applied too but with DMABOUNCE removed from Kconfig of the subarch of the galaxy as far as I can tell and the placeholder added to struct net_device in their v2.1 diff, has to be removed too. cifs.ko may be more complicated than tun, good luck. Unless you've personal interest to familiarize with the enviroment and the arm assmbly like I had, I would wait the source to released, it has to be released eventually to comply with the GPLv2.
Thankyou Newmail!!
I've tryed VPNC 0.99 and works great!!
You have only to type from terminal: insmod /system/folder/tun.ko
After that you can use VPNC...
I've found an issue with the FQDN of the VPN gateway... solved setting the IP address
Just a question:
when I'll update my JPK.. what I have to do to recompile the tun.ko?
Can you write here the procedure?
Cheers
Paolo

OK, but is the placeholder field at the end of the net_device struct?
If so it shouldn't matter and a module cross compiled from the 2.6.29 source should be OK. The absence of DMABOUNCE shouldn't matter for tun.ko either.
In theory you should be able to clone the AOSP git kernel repo and use that kernel for building a module, as long as the module itself doesn't actually use changes that have been made by Samsung (unlikely).
The .config used probably does deserve some attention though, as you have done.

Glad it works great for you too. So the tun.ko has to be recompiled if they alter .config. It may work but it's not guaranteed. The procedure is nasty and hard to document and I don't have enough time for that sorry. But I'm sure we'll get the source when there will be an official Froyo release that is shipped to all phones so I wouldn't worry.

The .config is the fundamental part, and it may be enough I'm not sure. There was a placeholder was a samsung customization done in the middle of net_device and that was removed in the Froyo ROM (initially I applied it). the DMABOUNCE removal affects the struct device that is part of net_device so a lot of stuff goes off by 4 bytes by tweaking that arch config option. That gets set in some Kconfig patched in by samsung. You're right that probably tun isn't affected by the DMABOUNCE but I tried to get the net_device size right (just in case) and it may affect other net modules.
Hi newmail, thanks so much for the tun.ko file, this is the first time I've managed to get VPNC working on my SGS!! One question though, I find I'm having to run insmod everytime I reboot the phone to make tun.ko available again, does anyone know if there's a way around this please so it stays permanently available? Many thanks!!
@bdl1969
I made a subdir in /system/lib called "modules" and placed my tun.ko there.
Now it's insmodded automagically..

Oh crap, that is bad news.
Then both the DMABOUNCE and the net_device are likely a problem.
That's a stupid way of doing things.

hmm I tried and it didn't work for me... are you sure? openvpn GUI runs insmod for me so it's no big deal.
That worked great for me, thanks for the suggestion! The only problem I found was that it caused my Good for Enterprise app to crash so I uninstalled and reinstalled it and then it was all fine. Only problem I'm left with now is when using VPNC, I make the VPN connection fine but I can't disconnect via the app, I have to bounce the network connection (eg. toggle WiFi) to drop the tunnel!
I compiled tun.ko using the 2.6.32 kernel from android git and your .config, but it won't load with dmesg saying "Unknown symbol mem_map". May I ask which kernel version did you use, and what arm toolchain are you using?

Probably you have discontigmem off in the .config. The platform of the galaxy isn't in the android kernel, it's in arch/arm/plat-s5pc11x (it's the thing that sets DMABOUNCE in v2.1 roms and I guess it doesn't on the JPK kernel).
You need to make a diff between android 2.6.29 and their tree, and apply it to the 2.6.32 kernel, then you need to solve enough rejects so that it can build external module. I didn't port the whole diff of course, just enough so make can start with the headers and .config all right. Then I built the module externally (adding the tun/ directory to their modules/ directory) but it should also work with just make modules setting CONFIG_TUN=m if you want to build it in-tree.
It's a bit tricky.. If you really need I can give you the broken diff to apply to the 2.6.32.9 android kernel. That is enough to build some module including tun.ko

It'd be great. I've already tried to do the patching. It compiles, but crashes the phone when loaded. Maybe your version is a bit better.

Did you find the source now that JPM has been released officially with Kies? I upgraded to JPM now, in the hope we get the source....
BTW, my tun.ko and my rfs_async.ko also works fine on JPM. I don't know about my ext4 build but I assume that will work too.
I used one CSC of this thread http://forum.xda-developers.com/showthread.php?t=802909 and I deleted the KOR /efs/nv_data* created by the JPK ROM (leaving the .nv_data.bak*). So with this combination of CSC from that thread, and MODEM and PDA from the JPM rar, I apparently restored the original product_id (SGSToolbox also says I'm back to the original product_id). Not that product_id matters but I thought I'd try that next time I flashed and apparently it worked fine...

The JPM source was avialable for a few hours on the samsung's site, did grap it. You can find it on megaupload somewhere. I couldn't manage to compile a working module from that source either (it now loads fine, but does a kernel panic when I try to mount a loop device formatted with ext4), but I'm sure that's my fault.
Hi guys.
I'm a newbie about compiling kernel,and this is my personal compiled kernel based on Hashcode's git source( stock branch),also with some tweaks which I think can improve the responsiveness without bringing extra power consumption( or as little as possible).
This kernel will also be my testing platform to do some MOD porting from Ezekeel's GLaDOS kernel.
Thanks to all great developers in XDA , especially:
-Hashcode & intersectRaven : for their git repo alone with a working .config. alone
-Ezekeel : for his so many great MODs on Nexus S(my phone) and Galaxy Nexus(will be my next phone)
-whistlestop : For his improvement on CM7 (I'm completely unfamiliar with the user land things about android, without him I'll be still using the stock ROM)
Features:
-LAZY cpufreq governor ported from GLaDOS(http://forum.xda-developers.com/showthread.php?t=1276092) with some tweaks.
-TUN compiled into kernel (especially important for people living in regions with strict network censorship like CHINA! F*ck the GreatFireWall)
-CIFS compiled into kernel along with NLS-utf8 for non-ASCII characters.( Now who cares the size of the internal flash?)
-Minor tweaks on ondemand governor to improve responsiveness.
ToDo:
-BLX porting from GLaDOS(http://forum.xda-developers.com/showthread.php?t=1257497)
-TouchWake porting from GLaDOS(http://forum.xda-developers.com/showthread.php?t=1239240)
Because I'm a newbie on kernel development and the MODs above both have some code in hardware drivers, so it will be a long time before accomplish.
The kernel source code seems to work on both CM9 and stock ROM.
So later I'll upload the flashable kernel zip for CM9 and stock ROM after some test.
Download:
CM7:http://www.mediafire.com/?2nsm9lb7ylm3gnl
In next post,I'll post the procedure for compiling the kernel and the wifi driver.
In this post I'll post the detailed procedure of compile the kernel.
1.Get the kernel source and wifi driver:
If you want to compile the kernel based on my tweak,
you can use my repo (fork from hashcode's source):https://github.com/adam900710/kernel_omap(branch stock)
Or you can just start from scratch without my tweak:https://github.com/KFire-Android/kernel_omap(only branch stock is tested)
If you are unfamiliar with git,you can learn it on the GitHub's help page:
http://help.github.com/
Tiwlan drivers from neither omapzoom nor CM7 works due the lack of given functions.
ONLY the wifi driver from Amazon seems work. So you need to download the whole zip from Amazon:
http://www.amazon.com/gp/help/customer/display.html?nodeId=200203720
The wifi driver locates in mydroid/hardware/ti/wlan/wl1283
2.Get the cross compile toolchain:
Yes,you can build from scratch according to CLFS(http://trac.cross-lfs.org/),but a newbie like me is glad to use the pre-compiled toolchain like sourcery G++. Omappedia recommanded 2010q1-202(https://sourcery.mentor.com/sgpp/lite/arm/portal/release1293), so I use it as the toolchain and it works well.
The self-extrated installation program will install the toolchian without any problem.
Also other toolchain is available like linaro , but according to the post by Ezekeel (http://rootzwiki.com/topic/10855-researchmythbuster-optimized-compiler-toolchains/) , there seems no obvious difference. So the out-of-box sourcery G++ is a good choice.
3.Compile the kernel.
Code:
cd kernel_omap #cd into your kernel
make mrproper #clean the source tree( normally you can skip)
make otter_android_defconfig #get the default .config (also you can copy it manually)
make ARCH=arm menuconfig #if you want,you can tweak the config of the kernel.This needs headers of ncurse
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi -j4 #you should make sure that the toolchain is in you PATH
After some CPU time, the kernel is built, in arch/arm/boot/zImage. Also the modules is built in other places.
Since I built all TUN/CIFS and so on into kernel,so there is no need to install the modules.
4.Compile the wifi driver:
Code:
cd mydroid/hardware/ti/wlan/wl1283/platforms/os/linux/ #cd into the building folder
make ARCH=arm KERNEL_DIR=/home/adam/kernel_omap CROSS_COMPILE=arm-none-linux-gnueabi- TNETW=1273 -j4 #you need to change the path of KERNEL_DIR
CAUTION: DO NOT add DEBUG=n OR DELETE TNETW=1273....
I don't know why,but if you do so,the wifi driver won't work properly.
5. Package the kernel into boot.img with ramdisk.
Thanks to DooMLord , in his git repo , you can download the tools needed.
https://github.com/DooMLoRD/Kindle-Fire-Kernel/tree/master/final_files
Only minor changes are needed for the path ,every thing elso works fine.
You can use the ramdisk extracted from any CM7 boot.img using the perl script.
Then just ./make_bootimg will do everythin for you.
Great i will test it

Hello everyone.
This guide will help you in building a kernel from source for your Nexus 10
Later, when 4.2 hits AOSP, i'll add a guide for building that too
You will need a computer running Linux / OSX to build the kernel, natively, or via a VM.
This guide assumes you’re running any Linux distro.
Getting a toolchain:
You need a toolchain to build the kernel.
The preferred one is Google’s toolchain, the same they use to build AOSP.
In a terminal, type:
Code:
git clone [url]https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.6/[/url]
export PATH=$PATH:$(pwd)/arm-linux-androideabi-4.6/bin
export CROSS_COMPILE=arm-linux-androideabi-
TIp: paste the export statements in your ~/.bashrc to have them exported each login.
Getting the kernel source:
The kernel source for Nexus devices is available from Google’s servers.
Source : https://android.googlesource.com/kernel/exynos
Github Mirror: https://github.com/chirayudesai/android_kernel_exynos
Open the terminal, and type the below commands to get the kernel source on your computer.
Code:
mkdir -p android/kernel
cd android/kernel
For Nexus 10, we get the exynos kernel sources.
Code:
git clone [url]https://android.googlesource.com/kernel/exynos[/url]
Next, we change our directory to the newly fetched source.
Type
Code:
cd exynos
Figuring out what to build:
Now, we need to figure out which revision to build.
You need to be exactly sure about this, otherwise there are chances that the compiled kernel won’t work.
The commit to build upon can be found by a few ways.
To get the kernel sources matching the device tree, type the below in the device tree.
Code:
git log kernel
Then type the below in the kernel tree
Code:
git checkout <commit>
The commit of the version running on the current review units is 52f6ab1 (probably), which is same as branch android-exynos-manta-3.4-jb-mr1-fr .
Compiling:
Name of defconfig: manta_defconfig
cd to the directory of the kernel source, then type the below in a terminal.
Code:
export ARCH=arm
export SUBARCH=arm
Code:
make <name_of_defconfig>
make
The kernel image will be ready at arch/arm/boot/zImage
To flash it, you need to make it into a boot.img, more on that later. when we have more sources.
Nice work, it's been nice to see some instructions on building additional kernel modules too.

Super awesome! I'm currently thoroughly:good: learning the rom building process with my nexus... ill get to this!
looking forward towards the development
Great! This is very helpful and useful
hey man, i got stuck at this point
Code:
git log kernel
it gives me this error
Code:
fatal: ambiguous argument 'kernel': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions
didn't really get that point... thanks :good:

It has to be typed in the device tree, which hasn't hit AOSP yet, but should soon.

oh, now i get this :good:
i was able to make a build tonight from aosp, waiting for my device to arrive & then ill be able to test. but as far as i could tell the output sizes were pretty on compared to the factory image files i extracted http://renzy.me/aoi
...just realized i didnt extract proprietary binaries.
Hello, Cdesai.
Thanks for your guide!
I will do my best to learn it.
so you say that you need to make the zImage into a boot.img (being a noob about this...) on my SGSII, I can flash zImages and boot.img, so I'm confused, lol

i think it depends on how youre flashing. with the sgsii youre prob using odin/heimdall & it might just overwrite the kernel. flashing with fastboot might require the boot.img cause it contains a ramdisk image after the kernel & is writing a partition. thats just my guess at least, someone else might have a better/more accurate answer for ya

yeah that's true, but for instance with HTC S-OFFed devices you don't even need to flash the boot.img....

you can extract the contents from the factory image & use getramdisk.py to get the ramdisk.img out of the current boot.img (or use this ramdisk.img)
then once youve compiled the kernel successfully, use mkbootimg from android_bootimg_tools.tar.gz to repack your boot.img.
if you want to just test...
fastboot boot [new-boot.img]
and flash if satisfied...
fastboot flash boot [new-boot.img]
just tested out if anyone wants some verification... screenshot
@cdesai, shouldn't we be using arm-eabi- instead of arm-linux-androideabi- as CROSS_COMPILE
Code:
git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/
export PATH=$PATH:$(pwd)/arm-eabi-4.6/bin
export CROSS_COMPILE=arm-eabi-
Building with arm-linux-androideabi- causes issues with kernel modules... here's an example of such an issue https://groups.google.com/forum/?fromgroups=#!topic/android-kernel/dzEIOVuxtEo
And the most updated kernel branch is android-exynos-manta-3.4-jb-mr1 not android-exynos-manta-3.4-jb-mr1-fr
Is there any chance of this becoming an OC kernel in the future?

Yes, I couldn't get md4 and cifs modules to load with arm-linux-androideabi-4.6:
<3>[ 1250.492203] md4: unknown relocation: 27
<4>[ 1260.230901] cifs: Unknown symbol _GLOBAL_OFFSET_TABLE_ (err 0)
However, with this:
git clone https://android.googlesource.com/platform/prebuilt
export PATH=$PATH:$PWD/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin
export CROSS_COMPILE=arm-eabi-
The modules load okay:
[email protected]:/mnt/shell/emulated/0 # lsmod
cifs 269223 0 - Live 0x00000000
md4 3442 0 - Live 0x00000000
(Now I have to work out why neither mount nor cifsmanager are working as expected...)

I know the reason... busybox needs to be patched... i guess it's something new in 3.4.5 kernel... I haven't done the patch yet

I had actually just got to the point of realising I could make it work by explicitly setting the unc path in mount command options. The missing patch would explain it.
Hello,
In order to debug the bluetooth problem, I'm trying to compile a kernel for the Captivate Glide. I can't get it to boot properly.
@steadfasterX 's SediROM is the highest-version ROM I know of on which bluetooth works so I've got it installed (version 2.1.2) on the phone.
The steps I've taken so far:
1. I have sedikernel from https://github.com/steadfasterX/kernel_samsung_i927 at commit 088aa4109ad144c583f32da5ffba7bac200f0575
2. I copied /proc/config.gz from a running phone, which contains CONFIG_LOCALVERSION="-sediKERNEL-v1.0", ungzipped it and saved it as .config . Haven't changed anything in it yet.
3. I ran `make CROSS_COMPILE=arm-linux-gnueabihf- zImage` (also tried arm-none-eabi- (both from Debian Jessie) as well as ~/Android/Sdk/ndk-bundle/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi- from the NDK)
4. I also made a TWRP backup of the boot partition, and used split_bootimg.pl from William Enck to split it into a kernel and initrd
5. I then ran mkbootimg with the initrd extracted in step 4 and the kernel obtained in step 3 in arch/arm/boot/zImage
6. Finally I flashed this new boot.img onto the phone with odin (Heimdall, specifically)
I see the white "SAMSUNG" logo (which is normal when booting) with a yellow-triangle with an exclamation mark in it. No further boot stage happens (no bootanim from sediROM). If I re-pack the original kernel with bootimg and flash that via odin, then after the next boot the yellow triangle changes into a blue one and sediROM boots correctly.
I'm a bit stuck at the moment, not sure what's going wrong there. Probably the kernel panics for some reason. Is there a way to read the kernel boot messages before android starts? Any help would be greatly appreciated.
Thanks!
Successful!
Thanks to a lot of help from @steadfasterX on IRC I finally managed to compile a working kernel
Here's a list of steps I had to follow in addition to https://github.com/steadfasterX/android_device_samsung_i927/blob/sediROM_CM-ICS/README.md :
1. as discussed on IRC, `repo sync` was not finding a branch. Needed to add
Code:
revision="refs/heads/ics-release"
in .repo/manifests/default.xml in the line with
Code:
CyanogenMod/android_vendor_qcom_opensource_v8
2. I removed the spurious comma in device/samsung/i927/cm.dependencies
3. In device/samsung/i927/, I changed vendorsetup.sh to point to vendorsetup.sh.nopatching rather than .patching (none of the patches could be applied)
4. lunch target was therefore the one with -eng, not -userdebug
5. I installed java 6 manually (didn't have sudo)
6. I installed schedtool
7. I adjusted the path to Java and my toolchain in build_sediROM.sh (taken from https://github.com/steadfasterX/android_buildtools )
8. I downgraded GNU make from 4.0 to 3.81
9. I installed linux-headers and created a symlink from /usr/include/asm-generic to /usr/include/asm
10. I changed the toolchain prefixes in device/samsung/i927/BoardConfig.mk to have 4.4.3 rather than 4.7
11. I built with
Code:
BUILDID=samsung/i927 LOKIFY=0 ../android_buildtools/build_sediROM.sh bootimage
12. I used the original ramdisk I had extracted from sediROM's boot image, rather than the one that was built (we discussed this on IRC too)
This got me a working kernel, yay

its really long guide. You have to replace kernel modules, wifi wouldnt work without modules.
Imho best is compile kernel, modules, replace zImage + modules in this
file and flash from recovery. You dont need to compile whole android just the kernel, you dont need java and other special things, this method is much more faster.

You are right for the kernel but we discussed on IRC to build ram disk too then you need all that stuff but most important he wants to build CM too.
However I'm always a fan of making it right so building a ram disk is the correct way of creating a bootimage. But to start its ok replacing kernel and modules first.

correct way is rebuild whole android, and reflash everything, wipe data/cache
You dont want to make new ramdisk without replace system. System and ramdisk bound together.
I hope you find something, and fix bluetooth or voip audio.
good luck

Well no and yes. I build kernels including ram disk without building system. This is not necessary as long both are compatible.
But you are right that booting fails when system and ram disk are not compatible so the correct way depends
However @uukgoblin I hope you get the fix you want :fingers-crossed:

would you tell me an example when kernel doesnt compatible with ramdisk but kernel does compatible with system?

No no my friend that's not what I said. :cyclops:
I meant if you have CM 9 as system you can build a boot image which includes kernel and a CM9 based ram disk without building cm9 system again. :laugh:
