So there has been a lack of relevant threads that explain my topic issue for me so I have decided to make one for myself and for others in the event that this happens. So right now I am using RemICS-UX 4.0.4 but I wanted to use Eng-matts ergybit 2.3 rom, because I am traveling and I need video calling from skype, but when I tried to flash this rom with odin, instal via cwm it goes into a bootloop. I also tried to flash Ruebens Lewa os since it uses gingerbread as a base, then I tried to acquire the ROM again but I git a bootloop. Sadly I didnt back up my stock rom, so I'm trying to find away to get back to the stock rom so I can fladh eng matts rom again.
So if anyone has anyway for me to get to my stock rom please help

You need to install rj kernel if you have an intl device and entropy kernel for usa device . After you install the kernel you can flash erygit rom. Just replace the kernel

maybe you should flash the rom again with cwm and if you get a bootloop just reset factory/cache works for me : )
Go into CWM Recovery (if possible) and flash rumirand r14 kernel and flash a new ROM.
Suggestion: Next time flash a ROM via CWM Recovery, ODIN flashing is easier to brick than CWM, CWM is very safe and you can always reset the bootmode if you're stuck somewhere!
Thanks guys

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.
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 .

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

I'll just point out this thread was dead since Sept 30 before you posted...
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......

Cheers to both of you, i think i will give checkrom ago as theres that many to choose from and im new to the rooted SGS2.
Hey everyone
A little while ago I jumped on the ICS bandwagon and flashed my villainrom 2.5-toting Optus i9100 to WanamLite 8.9, via CWM Recovery.
its been buggy as hell and the phone has turned to garbage ever since, with random freezing, touch input not responding, et cetera.
my question is - should i have flashed to one of the leaked samsung ICS ROMs via ODIN before updating to wanamlite via CWM Recovery?
i remember back in the SGS days, when moving from 2.1/2.2 to 2.3, you had to flash a generic 2.3 ROM via ODIN before you could flash a custom one. flashing a gingerbread darky's ROM over a froyo custom ROM directly using CWM caused all kinds of problems.
now that the official Samsung XXLPQ ICS is out, i want to flash to a pre-rooted version of it with CF-Root kernel (the ones that wanam himself has uploaded). but should i flash via ODIN to an official ICS first, and then root + flash the wanam custom version, just like i had to do when going from 2.2 to 2.3 on my original SGS?

Sorry for the previous post i clicked it while it ways empty by wrong
Just get ur phone into download mode and flash the stock jpq
After that do wipe cache and factory and ull be good to go
isn't the problem with doing that the fact that the bootloader will be upgraded as well, meaning i can't reset the flash counter with my USB jig anymore?

Not really needed .
But this is what i always do with any major upgrade or new custom rom .
titanium backup and nandroid backup
Wipe.format system data cache .
Install stock rom of same version
Root with CWM and Root kernel.
Flash new rom .
result no problems .

Restore backed up apps .
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.

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

yep this part i know from my Xperia S
Apologies for the desperate newbie question, but here goes--
I have followed the instructions in the stickied tutorials or tried to follow them so far. I rooted my SGH-i777 using framaroot. No problem there.
I got Mobile ODIN and the latest siyah CWM. I flashed the kernel.
When I try to power on I get stuck at "SAMSUNG" and then phone appears to power off.
I can get into recovery mode using vol up, vol down and power. I see the Siyah screen, etc. But that's as far as I can go.
HELP!
It seems to be that you flashed the wrong kernel what kind of ROM are you running touchwiz or aosp

Thanks for your response. I flashed the latest Siyah kernel after reading the "How to Flash Custom Binaries Without Ever Incrementing the Flash Counter!!" thread. FWIW in recovery mode it says "CWM-based Recovery v6.0.1.2-Siyah"
I had actually factory reset my SGH-i777 before rooting and flashing so I was running the Touchwiz that comes stock with the SGH-i777.
Any steps I can take to get out from under this rock? :crying:

Yes. Not to worry.
It sounds like the system is incompatible with the kernel. You didn't say which version of the OS you were running before you installed the kernel. Do you remember what it was? Which stock comes with the phone would depend on how old the phone is.
How to proceed depends on what you want to do. If you want to install custom firmware, then I would suggest that you flash one of the stock plus root packages with Odin, and then use Mobile Odin lite or Mobile Odin pro to install the correct custom kernel, meaning one that is compatible with the system that you chose.

It was 4.1.2. The phone was from near launch but I've upgraded the OS as Samsung has released them.
Ultimately I'd like to end up with CM10.1, but obviously that's a secondary concern at this point to a working phone

Here it is (the stock + root rom): http://forum.xda-developers.com/showthread.php?t=2322046
It doesn't hurt to do some looking.
Use Odin v1.85 for the flashing (google it).
Then find a kernel for your phone (don't try Siyah again :b), like for example, Entrophy's kernel, and flash the zimage file using mobile odin.

OK. The AJK v3.0 NoSwap kernel is the only kernel compatible with stock AT&T JB 4.1.2. However, unless you can get it onto your sd card, it won't do you any good at this point.
So I would suggest you flash UCLL6 stock plus root which is 4.0.4 from here. The OP has the complete guide, and links to working custom kernels. Once you get it up and going with a custom kernel, you can then flash CM 10.1, or anything else you want.
Edit: Cooked v1.6 as suggested by azeem40 is not Odin flashable. It is a CWM flashable zip, so you would have the same issue getting it onto your sd card. The above is your quickest route.
