Is it ok to flash a custom kernel on top of another custom kernel?
Sent from my GT-I9100 using xda premium
You dont need to revert on the original one before flash another custom. But you need to format dalvik cache and cache in recovery before flashing or you probably have a bootloop.
I suggest to make a backup of the rom in recovery, so If something goes wrong you can enter recovery and have the latest known working rom back in 2 minutes.
Please note flashing kernels always have a very small chance to corrupt your efs partition, its suggested to backup your efs folder before start play with roms and kernels. How to backup the efs, use the search tool of the forum

Thanks for that. I know how to backup efs. Can i just use nitrality instead of ADB? To flash ROMs does it need to be in a specific firmware like sgsl or is it ok to have different firmware from the base of a custom rom?

I know my english sux sry:
Depends on the kernel but usually it is listed in the kernel thread the how to (odin or clockworkmod), clockworkmode is already on your phone if you rooted it with cf-root.
Now, to enter clockworkmod recovery, just push volume up + home + power button until the S2 bootlogo appears, then wait few seconds.
About the kernel type, i always flashed any kernel despite of my baseband, the difference is not so big.
if something is not working, you can always youse the nandroid backup (the backup done with the recovery cwm (up+home+power) and get back to the previous rom with previous kernel.
Im not really in the kernel "how to" someone else can prolly give you more detailed info, but as for me, i flashed ninphetamine 2.05 and 2.1.3 in cwm and it worked.
But.. as always, the kernel developers got a how to install in their kernel thread, so just read those and be sure about if you need odin or clockworkmod, if you are not sure, DONT flash anything until you are sure on how to proceed or wich system to use for flashing, better keep an old kernel with a working phone than have a brick to hold the papers
PS: also almost all the roms on the S2 forum are flashable with the clockworkmod, only few (like the lite'ning) are flashable with odin.
Again, i know im boring, dont proceed if you are not sure, better ask 10 times instead brick your phone

Yes not a problem flash as per the custom kernel instructions .
Kernel can be changed within an individual firmware or custom rom .

Thanks for the reply guys. Coming back to my second question. What if i have KF1 and the rom i want to flash has a base of KI3, should i flash to stock KI3 first before flashing the custom rom or is it ok to flash a KI3 custom rom without flashing first to stock KI3?
Sent from my GT-I9100 using xda premium
The custom rom first, the kernel after.
I got the habbit to boot succesfully at least once the custom rom. If everything is ok i then flash the kernel. Better do 1 task at time.
You can decide to try the rom without change the kernel..and try a different one if you experience battery drain or other problems.

If i am on KH3 and want to flash a custom rom based on KI4 then i would flash stock KI4 and KI4 root first .
Custom rom flashed i will often try a different kernel later .

from my experience
I have found that when i upgraded rom from gingerbread to ics that most custom kernals work with these roms ie now running with xxlpw ics (from gingerbread) with xwlp7 kernal. from what i have read on other posts and threads i could swap kernal to siya or any other as the mega good developers have made them (hotswappable) interchangeable as previous reply said swapping kernal might give you better battery or solve overheat probs.
Eg iwas running darkys rom with siya kernal v?something my phone rocketed temp in short time so i swapped kernal for an up to date one (could have used older one) it solved problem.
Anyone feel free to correct explination im still learning too lol

Hi!
I'm a total noob. This is my first android phone. I've read everything about rooting, and I'd like to install a custom rom, but I'd like to save the stock rom/kernel first. I've found this topic: http://forum.xda-developers.com/showthread.php?t=1075278
I don't really know if these are what I need. Also, I have an xwkf3 device, but it's slightly branded for hungarian T-mobile (the browser has a different name and icon, and it also had every network setting by default).
So, basically I either need someone to tell me which one to download, or better yet, how to create a backup of the whole thing.
Yet again, I'm sorry for asking something probably really stupid. I've tried to google it many times, but I failed to find an answer. Thanks for everyone in advance.
Are you rooted already? If so just boot into ClockworkMod recovery (cwm) and then navigate to backup. (navigate using volume buttons and use home to select)

Here is the kernel rooting thread.
http://forum.xda-developers.com/showthread.php?t=1103399
Dial *#1234# into the phone dialer to find out what firmware you have installed.
Root using chainfires method and make a full backup via CWM.
Flash away. But make sure the Rom/firmware is for your device. Eg i9100 international.
Good luck.

I'm not rooted yet. If I understood everything correctly, the safe kernel is the same for branded/unbranded devices, and only the rom is different?
I'm currently downloading both secure and insecure kernels. After rooting, can I revert back to the secure one to install custom roms?
BTW, thank you for your quick answer

I'm not positive but I think if you are rooted and install a stock kernel (without root) you will lose root and won't be able to flash custom roms or make Backups. Its really easy to root, just find the appropriate insecure kernel, flash it with Odin, make backup, and then try new roms!

Don't flash back to stock kernel.
Use a jig if you want to get rid of the yellow triangle.
Edit: after flashing one of the cfroot kernels make sure you can get into CWM recovery mode. Vol up+power+home
If you can then you're ok to follow the instructions of the Rom you want to flash.

Thank you. One last question, if I may. Some of the roms I'd try use different kernels, then mine. If I install one of those, and want to revert the phone to factory rom, and kernel, should I root it again with an insecure kernel according to the rom, or one according to my device's current, factory rom?
You will probably find that the Rom kernel will be rooted and have CWM. Just check in the 1st post or 2 of the roms thread.
If you use CWM and make a backup of your stock Rom, after you root now but before you flash any other Rom, you can restore with CWM to get back to stock firmware.

To fully return to stock you have to flash a stock rom and stock kernel from Odin. The rom that you want to back up will be a stock rom but it will be rooted because of the rooted kernel. So yea, flashing stock firmware and kernel is the only way to get back to fully stock.

But if I restore my backup rom, and flash it with an original kernel, it would be unrooted, and basically the phoen would be just as it is right now. Is that right?

hi i have the same problem i want to root my gt 2 p5110 but i have to come back at the original values before june and can't loos the warranty....can you help me?
Hi,
I really want to get pure ics on my galaxy s II. Currently i'm on 2.3.4 gingerbread, unrooted.
I have asked a few questions about how to root my phone, and found a pretty straight forward tutorial, that users on xda have said is great to follow:
jayceooi.com/2011/08/04/how-to-root-samsung-galaxy-s2-with-cf-root-video
Rooting the phone appears to be pretty straight forward using the above tutorial, but finding the correct rom is what im not so sure about.
Users on xda have told me to use:
forum.xda developers.com/show....php?t=1075278 , to find a rom, specifically the ones just above ++++++ [Frankenstein Firmwares] +++++++
The only problem is, how do i know which one to use, i gather its going to be the 4.0.3 roms, but there are so many varients for different countries, which one is for me?
Does it matter which one i choose? Is there differences between them?
Thanks,
correct country
Hi, I'm not sure what other differences there are, but I know if you use the wrong countries Rom, the keyboard layout will be different to the one you are expecting, and as far as I know, there is no way of correcting this.
If you are going to use English as your main language then you can update to any rom as all the rooms support English primarily .
You can upgrade to the latest ics rom which is xwlp4, you can also find the matching cf root for the rom if you need root
#*posted on the move *#
Does that mean I would have to use another rooting method in order to use the new ics rom, or can I use the tutorial I posted previously?
Currently my kernel is XWKI4, and according to that tutorial I must find the insecure kernel that is closest to mine, what must be done differently?
Just flash any root kernel and your done. This will give root, su, super user, busy box and custom CWM Recovery for flashing, wiping, restore & backup etc.
Siyahkernel for example, can flash via Odin .tar or CWM recovery .zip
http://www.gokhanmoral.com/gm/2012/04/06/siyahkernel-v3-0-2/
Use could also use Chainfire CF-root kernel also found in XDA.
Sent from my GT-I9100 using xda premium
I'm sorry I don't understand what your trying to say.
Are you saying I need to use another kernel for cfroot, which will be capable of booting the new ics rom
Kernels are specific to GB or ICS. Not interchangeable.
Sorry, gave you the wrong link for siyahkernel GB.
http://www.gokhanmoral.com/gm/2012/03/19/siyahkernel-v2-6-14/
From there you can nandroid backup in cwm recovery and also backup and user apps and data with bavkup root apps such as; my backup root or titanium backup.
Then you can flash any custom ICS ROM of your choosing. Listening ROM is excellent with few bugs. It will come with a earlier version of siyahkernel, which has a few issues with wifi toggle, so suggest to flash the latest ICS kernel from the link I previously posted or from his thread here in XDA.
http://forum.xda-developers.com/showthread.php?t=1095274
Edit; important to do a full system wipe when changing rom from a different Android base. Wipe system,data, cache,dalvik in cwm recovery.
Another method would be to factory reset, wipe cache in recovery and power off. Enter download mode (volume up+power) release only when on dl mode. Have lies drivers on PC,but shut down lies and use Odin to flash the .tar litening rom. Done
Many methods and choices

Hi S2 user, :angel:
I will buy a new S2 phone soon. I need a little help from you guys. I need to know something about S2 :laugh:
My old phone is Xperia Arc S. This phone need following step to flash kernel and rom.
Kernel:
For flash a new kernel, I need to unlocked the bootloader first. Then this phone can flash any kernel anytime. But unlocking the bootloader will void the warranty.
Rom:
For flash a new rom, as long as the rom does not need to have specific kernel, in other word, stock based rom, no unlocked bootloader required. Just install the CWM and flash the rom.
How about S2 guys? Do I need to unlock something before flash kernel and rom? Can someone explain clearly or likes how I explain my old phone.
p/s- i read in some thread, doing a factory reset in cwm will make S2 brick? hard brick? can't even power on the phone. OMG is it true?
its very scary because in Xperia Arc S, i always flash a new rom. flasholic
I don't want my new S2 brick

You don't have to unlock. Just download Odin and flash all the ROMs/kernels you want. As for the cwm brick bug, your phone will only brick if you factory reset through CWM in 4.0.4. In other versions you should be fine.

You factory reset when installing ROMs to make sure there are no errors. Plus with siyah kernels, you can't be 100% sure your phone won't brick when factory reset in CWM. Best is to flash 4.0.3 before doing anything else.

Guys.. 1 more question.
When I get my S2, I plan to flash custom rom like aosp or aokp but not stock rom.
Do I need to root my S2 first before flash any rom? Because my Xperia Arc S, I do not need to root because root come inside with the custom rom zip. So when I flash a new rom, my Xperia automatically root. No need to do other step.
I'm curious about this because I see in some thread, talking about cf root or something like that. The thread is very updated. Looks like it very necessary to do it at least once to have root before flash any custom rom.
Please explain for me about this root. Thanks guys.

I'm not sure about CF root though. Although the ROM I am in now has built in kernels, I still think its best to root first as some ROMs may not have the built in kernel (never searched other ROMs not entirely sure). I might recomment siyah kernel though

Some people want to simple root their phone and don't care too much for custom roms and stuff. So for such people, they can simply root their phone using one of the many rooting methods mentioned.
However, if your primary aim is to install a custom rom/ kernel, you can use Odin to flash a custom kernel on your phone. (like siyah, dorimanx, Philz, the list goes on..) and you'll have root. Thereafter you can install a custom rom compatible with the kernel. Earlier on it was simple. Flash siyah or dorimanx and any custom rom will work on it. Kinda like a 'one size fits all' deal. However, right now with new mali drivers etc, some versions of a kernel are reqd based on which rom you plan to install. (JB with new mali drivers or JB without those new mali drivers/ICS)
CF-Root is the method I'd used..but right now it's not recommended, since if you're on certain 4.0.4 firmware, that is susceptible to the emmc brickbug I'm sure you've read about. Siyah, dori, etc kernels are safe.

There are two ways of flashing a kernel.
1. Use the .tar version of the kernel and flash via Odin
(the same way you'd flash the cf-root kernel you'd mentioned in a post above. I'll assume you know the steps as they're mentioned in chainfire's post. Or there are many posts on that topic)
Advantages: tried and tested route, simple one step method. You're rooted and have a custom kernel in about 30 secs.
Disadvantage: You rely on Odin and the connection to your computer which some don't trust. Increases flash counter.
2. Use the .zip version of the kernel and flash via CWM.
Since in this case you need CWM to start off with, you can use Rachmat3's method described HERE to get temporary CWM first.
Advantages: No computer needed. Everything happens through your phone. Flash counter isnt increased.
Disadvantages: Can be a little finicky at times..but you'll get there eventually. Involves 2 steps. First get temporary CWM, then install custom kernel via cwm.
You can start off with a very popular kernel. Gokhanmoral's siyah kernel.Both the zip and tar versions are available downloadable from HERE

Another disadvantage of "not using" odin is when you cant enter cwm.
I use cwm and mobile odin.I flashed a kernel and couldnt access cwm nor phone would boot.
So I had to fix it using my pc via odin.
guys im new here on galaxy s2 thread so kindly do not judge me if i ask noob things
i want to flash AOKP for galaxy s2 and i found 2 of them Revolt and thunder roms
download both + dorimanx kernel placed on SD going into CWM trying to flash kernel and rom but im getting this message :
E:signature verification failed !!
Like just about everything else on here, 'E:signature verification failed !!' has been covered many many times on here (Including a couple of times over the past few weeks). Search for those threads, your answer will be in one of them.
i think i have the stock recovery !!
flashing this Cf-root throw odin will give me the CWM ??
Having stock recovery would explain your problem. If you flash the correct CFRoot kernel via Odin, yes, you will have a rooted phone + CWM. However, many people prefer to simply flash the Odin version of a custom kernel (like Siyah) to achieve this aim these days (Given the issues with 4.0.4 stock kernels, which CFRoot is, and the brickbug). Find the relevant Odin flashable version of Siyah for the Android version you're running; check the Siyah threads for which build is compatible with which version of Android (should be on the first page).
all the Cf-root is ICS and im running JB what i can do in that case ??
all i want to access cwm to flash rom and kernel
This recovery I have
Sent from my LT26i using Tapatalk 2
Which as you said is stock recovery. You can flash temporary versions of CWM from stock recovery, but these only persists until the next reboot/aren't permanent. Make life easy for yourself & flash the Odin version of a rooted kernel as advised in my PP (Use CFRoot if you really want to, just don't do a wipe from CWM while you're running it, wait till you're running a custom kernel before doing any wipes).
Edit - You're welcome, BTW.

thanks for your help
OK. This is my final post to this thread. I tire very quickly of having to repeat myself.
For the last time...Go to the Siyah threads. Work out which Siyah build you need for the Android version you're running. Get the Odin flashable version of that kernel. Reboot into download mode & flash it with Odin.
Done.

yep this part i know from my Xperia S
Wish i posted the thread in the right place.
I have gt-i9300 and want to root it.
Here are some questions=
Q1. In which process of flashing i am modifying my bootloader? (while flashing cwm, kernal etc..)
Q2. When i flash stock ROM through Odin, do i restore the kernal, recovery and the flash counter?
Q.3 Is flashing a ROM after root is a risky thing?
Q.4 Can I flash a rom directly after rooting and flashing CWM? (without changing kernal?)
Q5. What is kernal compatibility? like some kernals are JB only. And does every ROM contains it's own kernal?
Q6. Is there a way to root and get cwm without getting the stupid yellow triangle?

hallo im also new to rooting but flashed cm10.1 yesterday with root and can share what i did.
i also got i9300 nordic version of the s3. and downloaded some files
odin 3.07
cfroot 3.64
cm10.1
gapps from 03-2013
i resettet my phone and enabled USB debugging and put the phone in download mode and startet up odin and made sure its connected and loaded cfroot.tar and flashed and the phone rebootet itself and installed the ness. apps for rooting. then i bootet up in recovery manager and went to install from sdcard and installed cm10.1 and then gapps and then did factory reset and dalvik wipe and rebootet and it bootet up CM10.1 and deleted /0 folder on the phone which was empty folder from previous touchwiz samsung rom
and yes there are risks but i did this 2 times. tw to cm10 and then back again but everything went problem free. so the risk ppl are talking about is mostly likely cuz some broke and if u mess up it breaks. so it can happen.
q1; when u flash cfroot the bootloader changed and it changes counter from 0 to 1.
q2: when u flash stock back with odin it flashes rom and bootloader/recovery but counter is the same but can be fixed easily. ( did it myself between my 2 flashes so when i flashed back to CM10 it still was on 1
q3: i think its everything thats risky. dont think root and rom flashing are more risky than others
q4: dont know what u mean exactly. i didnt mess with kernals. CM10.1 has a good one i think.
q5: dont either
q6: i dont have any yelly triagle on my cfroot+cm10.1. theres a lille read thing in the left corner like 2mm long that shows u got flashed.
hope it helps.

For kernels that support both go here or here. At the moment Siyah or Goggy Max are the people's choices I assume.
Q.3 Is flashing a ROM after root is a risky thing?
Any flashing involves risk from almost no risk to a much bigger risk for those that dont read the basics and follow instructions .
Root voids warranty .
Q5. What is kernal compatibility? like some kernals are JB only. And does every ROM contains it's own kernal?
yes and yes .
Q2. When i flash stock ROM through Odin, do i restore the kernal, recovery and the flash counter?
NO read the basic faqs and guides all stickied .
Q.4 Can I flash a rom directly after rooting and flashing CWM? (without changing kernal?)
YES
and also i need a kernal for both AOSP and Samsung roms which i can't find
IT is inside the rom .
I suggest you bother to read the faqs and guides or join the help i bricked my phone club .

1. You can flash boooader separately or when you flash stock roms. (I can be wrong but this is what I know)
2. I never done that but yes for first two, not sure about flash counter, you may still have to clear them with TA first.
3. As above answer, it's always risky to do stuff without proper knowledge and no guarantees even after proper knowledge but mostly no.
4. Yes.
5. Kernels are essential part of your phone and they are compatible with your os version only and also ur phone model. So if a kernel is for s3 4.2.2, you can't flash it over to amy other model or os version. Yes for second part.
6. No. Triangle away may remove your flashing counter but as long as you have custom anything and your rom status is modified that triangle will be there.

Siyah supports both cm and stock. Yes, you cam flash cm over stock or siyah kernel.
You have to flash your kernel again after every rom flash.

As long as the rom comes with a kernel, which is the normal base, you have to flash the kernel again. Usually you can do this direct from recovery before the full reboot.
As long as the kernel supports your rom type (see each kernel's thread for it), you should be fine as long as you follow the instructions.

bootloader no clue, I never touched it, too dangerous to mess up stuff.
for flashing googy, usually you do it in CWM or via Odin. Check out the thread and read the instructions. Syiah's thread also got a huge amount of guides in the first couple of posts and they should be valid somehow for Googy as well as it is based on Siyah.

Please do not start messing with bootloaders .
Logic says read the instructions for the kernel you want to flash .
Its a CWM file and flashed via recovery .
You really should bother yourself to read the basic faqs and guide .

The bootloader isn't modified. The bootloader *shows* modified by reading other data.
