How To: Extract a Kernel From a ROM

There's a kernel you like, but it is only available packaged with the developer's ROM. You like the features of a different ROM, but want to use the kernel of the first ROM. Or maybe you want to keep your stock ROM, but use a kernel packaged in a custom ROM. What do you do? You extract the kernel (this sounds a lot cooler than it actually is).

Standard disclaimer: this procedure should not be done by anyone ever. But if you do do it and blow your phone up into tiny little pieces, I am not responsible.

You might have noticed that all ROMs and kernels come in zip files, which you install in ClockworkMod Recovery or Team Win Recovery Project. Ever tried looking in one of those zip files? You'll find a bunch of files and folders. One of these files, called "zImage", is the kernel. Here is how to take a kernel out of a ROM to use in another ROM or by itself, in 3 (you should already have done step 0 but I put it there just in case) easy steps:

0) Make a backup of your phone using Recovery. This is extremely important - if you mess anything up, you'll have a system backup as a restore point. If you don't know how to do this or what I'm talking about, your not screwed.

1) If you don't already have it, download Root Explorer or ES file manager - this will let you view and modify the internals of zip files without extracting them. This is important because other users have reported problems with the unzip ROM>modify ROM>re-zip ROM method.

2) On your computer, unzip the ROM you want to extract the kernel from (it's ok to unzip this ROM since you won't be flashing it) and find the "zImage" file. It will be in a folder called "kernel_update". Set this file aside.

Now, if you are putting the extracted kernel into a ROM that comes with its own kernel, go to step 3a. If the ROM does not come with its own kernel or you want to install the extracted kernel without a ROM, go to step 3b.

3a) Place the ROM you plan on flashing as well as the extracted "zImage" file onto the root of your phone's SD card. Using file manager, look inside the ROM and find the "kernel_update" folder and delete the "zImage" file there, then replace it with the "zImage" from step 2. That's it, you're done! Now just boot into Recovery and flash.

3b) This step is for installing the extracted kernel by itself, and for users who want to use the extracted kernel with a ROM that does not come with its own kernel. To insert a kernel into a ROM that does not come with its own kernel is beyond the scope of this guide (it's a bit messier). So for those users it is easiest to first flash your ROM, then flash the kernel as a separate zip. To do this, first download any stand-alone kernel. Then place both the stand-alone kernel as well as the "zImage" from step 2 onto the root of your SD card. Using file manager, Find the "kernel_update" folder in the stand-alone kernel zip, delete "zImage" and replace it with the "zImage" from step 2. That's it, you're done! Now just boot into Recovery and flash.

Hello

I've searched the internet up and down.

Does Samsung give us an oppertunity, to download org. ROM?

I need for several devices, both for development and updating my phones.

Samsung KIES software is so crappy, that i rather do it myself.

I hope the answer isn't here, so it isn't me :)

Hope you guys understand, english isn't my first language
[General Questions and Answers] kenbonilla:
I'm not sure what you are asking for. Are you looking for the original ROM that came with the phone? Google should be able to point you in the right direction. And there is no need to ever use kies, you can back up everything easier with third party apps like clockwork mod or titanium backup. For me kies is just bloatware that never works right
[General Questions and Answers] paintball23456:

Very thorough description phositadc, thanks!
[Droid RAZR M General] jmctitan:
"Second, I don't like the fact that the dock icons have labels beneath them."

Just a note that you can remove the labels in the dock.

Thanks for the review.
[Droid RAZR M General] Not_A_Dev:
Pretty much mirrors my experience with this device. Except, I use Apex launcher rather than Nova. Also, coming from a Droid X2, this phone has a tendency to slip out of my hand sometimes (gives me a heart attack).
[Droid RAZR M General] phositadc:
Yeah none of the reviews mention it but I agree it's worth noting that the phone is pretty slippery (due to its size, materials, or both). I was planning to go without a case but if cruzerlite or diztronic makes one I'll probably get one.

I'd have to agree with your mini-review phositadc. I just popped the sim in and started setting this phone up. I have a rooted VZW GS3 and this DE razr is much more suited to me. The samsung is going up on craigs!
[Droid RAZR M General] lsxmma:
You can also use custom icons with the stock launcher.
[Droid RAZR M General] jmctitan:
Ugh, sorry. I was mistaken. My apologies for getting your hopes up.
[Droid RAZR M General] lsxmma:
Just replace the stock UI icons with custom icons and it solves your issue.
[Droid RAZR M General] jmctitan:
How do you replace the stock icons? Thanks in advance.
[Droid RAZR M General] lsxmma:
I downloaded desktop vizualizer to make an icon. Than removed the stock icon I wanted to replace it with. Then you just drag the new icon in its place.

Hope this helps.
[Droid RAZR M General] jmctitan:
Thanks.

muffled audio.

I got a Razor M for my wife & she's been complaining about voice quality, says it sounds very muffled. So it's going back to Amazon for replacement, we'll see if the 2nd one will be any better.
[Droid RAZR M General] phositadc:
Update

I'll post this at the end of my OP, but just to add a little more:

Call quality is fine. Honestly, I'm not a call quality audiophile. Everything is loud and clear, just like it has been on pretty much every cell phone I've owned in the past few years. Nothing unusual to report.

GPS is really solid. It locks MUCH more quickly than either the Galaxy Nexus or the HTC One S. GPS Status also shows that it both sees and uses a few more satellites than the One S does. For instance, I was sitting near a window in my living room, and the M was using 10/19 satellites, while the One S was using 7/17. GPS gets a thumbs up.

And this is probably something I'll create a separate thread on, but I'm getting some wakelocks on the M that I do not get on the One S. I have the M and the One S setup identically. When the One S's screen is off, the phone is in deep sleep. The battery settings show that the phone is almost never awake unless the screen is on. The M, by contrast, is frequently awake for very short periods of time even when the screen is off. It does not seem to be causing much battery drain, as I'm still losing well less than 1% per hour on wifi (when the screen is off), but it is nevertheless worth noting because presumably it should not be happening. I'm in the process of trying to figure out what is causing the wakelocks, but haven't figured it out yet. I somehow suspect it has something to do with "phone idle" taking up a much higher percentage of battery consumption than I've seen on other phones. In any event, I'll start a separate thread on this when I gather a bit more info, but just something to be aware of.
[Droid RAZR M General] huatz84:
Nice review!!! Love the edge to edge display. It doesn't hit the shelves in my country yet. Hope we got it with intel Atom cpu coz I heard Razr M with Atom cpu in UK.
[Droid RAZR M General] mgerbasio:
I use the phone a lot, about 3000 peak minutes a month. I find the phone sounds better than just about any cell phone I've used. The best part is the phone is nice and loud. My use is in NYC where the streets are noisy, and, I work on construction sites. This phone is far better with notifications, earpiece and rear speaker than any other phone I've used.

Battery life for me is a mixed bag. I can get down to 1.5%/hour so sitting on my desk I easily get a day, probably two in standby. So far, in use, it hasn't been that good. After about eight hours, the battery is down to 15%. The battery charges pretty fast though so it takes the sting out of being off charger with heavy use during the day.

Screen for me is as good as anything else I've used. I rather have the D3 screen which could be better viewed in daylight. I don't use my phone for movies, games or serious photos so the screen doesn't need to be retina.
[Droid RAZR M General] joe_sun:
Thanks for the info guys. The wife is CRAZY about the circle widgets and for that reason alone she's probably going get this phone but the mediocre camera could be the reason she goes with an S3. You never know what she's going to like or why. Example, her favorite rifle of mine is my FAL. Why? Because it has a carrying handle and "it's just handy." She bought her Toyota Matrix because it had a wiper on the back window and really liked that feature. lol
[Droid RAZR M General] cowisland:
Thanks for a great review. I played with the phone at a Verizon store and it did not strike me as particularly snappy. However, that was probably due to the blur launcher and an abused display specimen.
[Droid RAZR M General] phositadc:
Yeah I think that is true... the one I used at the store was mediocre as are many store devices... but the one I bought is as fast and smooth as any android device I've used.
[Galaxy S III General] mrjoy:
Hello guys... I'm galaxy S3 user. I just want to know that Galaxy s3 & htc one x has same 1 GB ram but for galaxy s3 its showing 778 mb ram in hardware information but htc showing proper 1 gb ram. why this is? Infact, i noticed all htc have same ram as in hardware information bar. Mean s3 have less ram acording to htc one x?
[Galaxy S III General] GuestK00280:
Some RAM is reserved for camera, hardware decoder, etc. I doubt HTC used separate memory chip for each of these, so ONE X software must be reporting false values.

BTW, there are 833 mbytes of RAM available on latest JB leaks, and enthusiasts are looking for a way to increase this number further.

[Galaxy S III General] IamIrene:

[Galaxy S III General] mrjoy:
Thanx all for giving information. But some says that ram reserved for system & some says reserved for camera & hardware.. hhhmmm then what about htc ram? Is it shows proper 1GB ram included reserved system ram or excluded system ram as sgs3 has.??? By mean as shows 778 mb out of 1GB then where is 222 mb ram which is left. Is 222 mb ram reserved for system use?
[Galaxy S III General] Geordie Lad:
One X has more free Ram but everyone who tried both says S3 uses it's Ram better, and the US proves bigger isn't always better.
[Galaxy S III General] SlimJ87D:
You are wrong. This has nothing to do with the phones themselves but chip manufacturers. Look at the HTC One X LTE versions, they only have 600mb of RAM.

Yes the International version has close to 1GB of RAM free. This is mostly due to Tegra 3 having dedicated video ram to their GPU where the Exynos and S4 do not.
[Galaxy S III General] mrjoy:
aahh.. means s3 does not have video ram???
[Galaxy S III General] SlimJ87D:
Yes, we can squeeze out as much ram as possible but I believe a good portion of it will always be reserved for hardware.

I did a lot of studies with my US One X and the International One X.

Anyways, to answer your question it is the Tegra 3 chip set that has 1GB of RAM, it's like that on the Asus transformer also.

Compare the US One S and One X, you see the same Ram usage pretty much and same SoC. But the international with Tegra 3 and everything else that uses a Tegra 3 from what I have seen (there might be some with 4glte radios that require ram also) has 1GB of RAM.
[Galaxy S III General] mrjoy:
it mean tegra 3 chip is more faster phone than galaxy s3.??? bcoz tegra 3 chip has 1 GB of RAM.
[Galaxy S III General] nodstuff:
No.

The S3 has 1gb of ram too.
[Galaxy S III General] SlimJ87D:
No, not at all. RAM, CPU and (if the gui is properly programmed) GPU can all affect how your phone functions and feels. The S3 uses a more better engineered chip set than the Tegra in the CPU and GPU department.

Most importantly is software though. As the way things are, if Android doesn't figure out a way to optimize their OS to universally work for any kind of hardware it might lose out to WP8.

Not in the hacking department though since WP8 will be closed source.
[Galaxy S III General] mrjoy:
@SlimJ87D

thnx for giving kind information.... I respect your answere.. :)
[Galaxy S III General] AndreiLux:
Tegras don't have dedicated GPU RAM, they don't differ to the Exynos in the way they handle that. The reason is purely software based, and some SoCs having reserved memory spaces for internal functions. I have now 856mB useable on my kernel for example.
[Galaxy S III General] sree_rag:
The leaked jb firmwares gives you 833mb ram.
[Galaxy S III General] SlimJ87D:
See that would make sense if every Tegra device from different companies like Asus, htc and Motorola, etc would have different ram uses since they all build their roms with custom ui, etc. Every company has their own custom kernels as well. But that is not the case, or is it a giant coincidence most if not all the Tegra devices show .950 gb free of memory? Including the Nexus 7.

xdaforums.com/showthread.php?t=1798299
[Galaxy S III General] AndreiLux:
Sorry but no you don't know what you are talking about, Nvidia does the basic platform kernel for their SoC, the manufacturers don't do anything more than adapt it. ROM also doesn't have anything to do with it
[Galaxy S III General] SlimJ87D:
I'm willing to believe that. Can you point to me some sources for my own benefit and education? Because around the boards everyone is saying the Tegra 3s have dedicated video ram. It would be an eye opener if you could prove otherwise.
[Galaxy S III General] AndreiLux:
I'm on my phone now so I won't be playing detective for you, just Google it. SoCs have a single memory chip embedded onto their packaging and nothing else. This supposed magic dedicated memory doesn't exist. Just like people were saying that all the memory on our devices goes to video/Mali but in reality we only have a 8mB framebuffer. We have actually 1GB virtual memory given to Mali, but it didn't mean anything since its shared memory.

Tegra had more memory free because it dynamically allocates these memory blocks as supposed of having them statically allocated like on Exynos and others. The disadvantage from this is that performance can suffer, as you can see in HOX HD video recording and it lagging sometime and not having a consistent framerate. On Exynos these things are DMA accessed, meaning any operation didn't go through the CPU but the function blocks like the hardware encoder/decoder gave direct memory access (DMA).
[Galaxy S III General] SlimJ87D:
Thanks, I'll research it further when I get the chance. So does the HOX have more problems when a program requests memory? That's what I got from your post. Have you studied the S4? Why is 400 mb of RAM nearly reserved?

The International HOX was capable of opening up nearly double the amount of programs than the 4G lte one before the memory manager started to dump the programs.

Thanks in advance.
[Galaxy S III General] btemtd:
From now on I think we should start refering the 1GB ram to the -=I9300=- GS3

You now cannot say the GS3 has only 1GB ram

Just to complicate matters, 1GB is not 1000mb.

The 1GB quoted by a manufacturer is 1000x1000x1000 bytes, but to a computer (ie your phone), 1GB is 1024x1024x1024 bytes.

In other words, if Sammy say your phone has 1GB, and all of it is free, your phone will say it has 931mb.

So in your example, it's not 778 + 222, it's 778 + 153.

Exactly.

[Galaxy S III General] LeoViotti:
That's usually correct for storage, not common in RAM. Unless things are totally different between computers and smartphones.
[Galaxy S III General] MinaseTaki:
this rule is for storage capacity only,memory (RAM) is 1GB = 1024 MB.

So yeah if sammy say we should have 1 GB free ,then our phone should show 1GB free (1024MB).
[Galaxy S III General] AndreiLux:
The only thing that gets measured in 1000's is platter hard-disks. Everything else build with transistor based memory cells is measured in powers of 2, including our own storage space, if it is solid state.

READ FIRST TWO POSTS TO GET IT RIGHT!!!!

Hey there,i am posting this for the ones that have problem with their ROM.(Doesn't matter whichever).Ok so this tutorial will explain what to do when your ROM doesn't work properly.If you have errors like "system.process.media has crashed" or "Unfortunately Google Play Store service has stop" or "Xperia Home has crashed" than this is tutorial for you step by step.This happened to me so i will explain what i've had to do to make my SXS work again.

WARNING!!!!

I am NOT responsible for any broken phone or damages or apocalypse or whatever kind of destruction!!!This process worked for me 100% but i also 100% not sure if this work on yours!!!

So this is third time it happens to me "half bricking" or not proper work of my system.And i only tried this on SXS i haven't tested it on any other Xperia line.
[Sony Xperia P, U, Sola, Go] DekinGBar:
So first thing first if you have a problem from the first post,than you can proceed further,this is not for totall bricked phones!You can try but I promise no success!

First step is installing flashtool on your windows/linux if you don't have. [I will put the download links in the third post]

Second step is downloading STOCK ROM

After you downloaded the ROM than extract it.

Third step: Open Flashtool folder on your PC and look for the folder "firmware"

Fourth step: Put the FTF file qhich you previously extracted from the ROM You downloaded into Flashtool>Firmware

Fifth step:eek:pen Flashtool and click the "thunder" icon

Sixth step:You will get 2 options Fastboot mode or Fladhboot mode.Select Flashboot and click OK
[Sony Xperia P, U, Sola, Go] DekinGBar:
Seventh step: Select the firmware.Yours will be the LT26i 6.1A.2.45 Generic.

Eighth step:leave everything as it is do not change anything else.In the upper right corner it should be ticked Wipe Data,Wipe Cach and Wipe Storage.If it is not ticked than tick it!!!!This step is the Most Important!!!!

9th step:Now do what your flashtool says.Just power off the phone and disconnect it from the usb.Than after the phone is switched off hold volume button down and plug in USB cable at the same time.Than if your LED light turns green it means you can sit back and get ready for the smooth phone without an errors :)

THIS WILL WHIPE YOUR ENTIRE STORAGE AND AS FAR AS I KNOW THERE IS NO WAY THAT CAN BE BACKED UP SINCE THE SONY PC COMPANION DOES NOT RECOGNIZE THE PHONE!!!!!!

Links in the forth post!!!

http://www.xdafileserver.nl/index.php?dir=Sony+(Ericsson)/SE+Xperia+S+(LT26i)/STOCK+ROMS. - The ROM And Flashtool!!!!For the ROM Choose ICS folder,than the LT26i_6.1.A.2.45_SG_Generic_(1257-6921).ftf.7z

If you have anymore questions feel free to ask this is a NOOB tutorial so if you are beginner dont be afraid...we were all beginners before this ;)))
