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

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.

ye but the problem cf-root only for ICS and im on JB so if i flash it and then flash JB kernel will do the job or i will stuck !?
sorry if i sound noob but frist time im dealing with Samsung its completly diffrent from Sony
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.
Rooted phone + CWM.
dude sorry but i'v found this
flashing this Siyah-s2-v6.0b4
and now i have cwm and flashed thunder rom
thanks for help and sorry for beeing noob here

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?
Sent from my GT-I9100 using xda premium
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.
Sent from my GT-I9100 using Tapatalk
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 .
jje
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

Im new to the whole SGS2 so needed a little help ive rooted my Galaxy and its on UK 2.3.5 stock rom my question is can i flash any rom i choose or is it like when rooting it when i had to get a kernel that matched.
The other thing is, is it worth buying Odin Mobile.
Cheers
Once you root your phone and have CWM recovery and not the stock one you can flash any ROM you choose.It has nothing to do with kernels but each ROM is based on a firmware so you should match your firmware to a ROM based on the same to start with and if you choose to stay with the same ROM then there are non-wipe ROMs that can be flashed over top without worries.Just be sure you read properly the install/flash instructions.Some ROMs need Odin to be flashed but most just need to be pasted to your internal-SD and then flashed in recovery mode.Ill leave a link below to my ROM where there is an instruction guide so you can read it to see what I mean.

It depends on how you have rooted ...... if as mentioned above you have CWM (means you have flashed a custom/insecure stock kernel) just flash a ROM with CWM Recovery like any ZIP but i'd advise you to reset the phone before that .... since you are on Stock ROM which is Odexed and all custom ROMs are deodexed you might end up in a bootloop also may i suggest CheckROM as it is simple to install and highly customizable thus i recommend this as your first flash......

else i use this site it's pretty awesome to keep track of things

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
I hope you guys can help me. Thanks

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.

The brick Bug problem by 4.0.4 only with Stock Kernel ! when you have 4.0.4 on your phone you flash a save Kernel (Siyah, Dorimanax .....) with Odin (only Odin not Cwm )
and it was save .After you can flash wath you want

I see. So the brick bug actually come from the kernel inside firmware 4.0.4. Not the entire 4.0.4 firmware. Is other custom kernel likes you mention (Siyah, ..) is 100% safe?

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.
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 .

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.

For kernels that support both go here or here. At the moment Siyah or Goggy Max are the people's choices I assume.

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.

Hi everyone!
Let me start off by saying that I am not one of those who directly ask questions before reading. Honestly, I have been reading from guide to guide and it is because of the many guides on the forum and Google that I have become confused on where to start.
I have rooted and flashed ROMs + kernels on my old phone, so I know most of how it works, but its the first time I use a Samsung phone, so I would really love some help to get started.
All in all, I have only few questions, but important ones I would love to be covered. Better safe than sorry, right?
Let's get started:
I am currently running stock JB - to get root I shall just flash CF-Root, or is anything else recommended?
Once rooted, is there any recovery I shall use that is more "stable" than any other? CWM, CWM Touch, TWRP etc.? Lets say I want to try NeatROM + Apolo kernel, will that require any specific recovery?
If I want to try different ROMs out, like to go from NeatROM to SlimBean to CM11, can I do all that by using the same recovery? I know about the full wipes, I just want to make sure I can flash other ROMs straight away or if I need to change things before?
That is all for now. Once this is covered up, I highly believe I can take care of myself in this huge community and to help others too once I get a little experienced
I say thanks in advance! Absolutely loving the forum here
Hmm,as all your questions are somehow recovery/kernel related,you may try flashing Philz kernel.It's basically a stock kernel+advanced cwm recovery.You'll get root too.Its cwm can flash all roms up to android 4.3.1.I would call this option a safe and easy bet.
Also,if you want to try kitkat roms,like cm11,you'll have to update to kitkat compatible recovery,like cwm 6.0.4.7 etc,first.

Thanks for the reply! Appreciate the help! From what I can see, that also roots the phone, so this could be the easiest way to go :good:
I assume you refer to this thread? http://forum.xda-developers.com/gal...lz-cwm6-stock-kernel-cwm6-root-exfat-t1877270
The latest build alone has all these builds lol:
PhilZ-cwm6-XWMS2-MOT-5.15.9.tar.md5
PhilZ-cwm6-XWMS2-MOT-5.15.9-signed.zip
PhilZ-cwm6-XWMS1-NEE-5.15.9-signed.zip
PhilZ-cwm6-XWMS1-NEE-5.15.9.tar.md5
PhilZ-cwm6-XWLSZ-OJC-5.15.9.tar.md5
PhilZ-cwm6-XWLSZ-OJC-5.15.9-signed.zip
Honestly, in the thread OP says this but I really need help to understand this further:

What kernel to choose:
The important part is the Kernel code:
XWLPX-NEE
Kernel code is in red (LPX), for this example, you need an LPX ROM. However, often, you can mix kernels when they are close: LPF kernel with LPG ROM...
NEE code doesn't matter at all, I add it for reference. It is the CSC
XW: mixed, often doesn't matter for close regions. For example, XW and XX are often interchangeable. However, mixing a BU with an XW ROM or inversly, sometimes works, but often ends in a bootloop. In that case, either boot into recovery or download mode to reflash

And one more question: It says cwm6, does this mean I shall use this recovery for JB or KK ROMs?
I am getting close to flashing, just need this final step
Look at your rom's build number and choose accordingly.To check,go to settings/about device.
Use this kernel only for stock/stock based JB or ICS,as it has older,kitkat incompatible, CWM.
To flash 4.4.x roms,you can do it by following these simple steps:
1.Download a 6.0.4.x or newer CWM for i9100.
2.Boot to Philz recovery.Do a nandroid backup.
3.Flash new CWM.
4.Reboot recovery.
5.Full wipe,then flash chosed kitkat rom+gapps.
6.Reboot and enjoy!!
Ok that is great help mate. Youre great person!
I just didnt quiet get the custom JB part then, to flash a custom JB such as the one on your signature, SlimSaber 4.3, I shall use...?
I promise this is the last question then I am good to go all thanks to you
With the CWM 6.0.3.2,which is latest in Philz kernel,you can flash all Jelly Bean roms(4.1.x to 4.3.1).This includes both stock samsung 4.1.2 Jelly Bean and custom JB roms,like AOSP(that SlimSaber 4.3.1 is),CM,AOKP and so on...Just no KitKat love.
Don't forget to do a nandroid backup and EFS(this is vital) backup in recovery before you start. Just in case you know.
Good luck!
