All,
I have a question regarding what kernels are 'compatible' with various versions of CWM. The reason I ask is because the CWM threads I see are usually bundled with a specific kernel, and without finding specific info about that, I'm led to assume that there's a dependency there.
Until yesterday I was running Bubby's stock rooted kernel. FWIW this is my 'upgrade' path:
Zedo V3(Bad LOS) -> Bubby's stock pulled EB30 with root retained - Great performance, maybe 3 instances of LOS in the 2 months that I've been running it.
Perusing the dev section I saw that NoCIQ was available but required CWM to flash. A search for CWM yielded a few threads. Wanting to have a rooted, and not stock kernel, I settled on the LostKernel/CWM5 package. After a few hiccups getting back to no yellow triangle, etc. Things seemed to be running fine. And they still are...mostly.
The one difference is that on my way in to work this morning - I ride train that passes through several 3g/4g coverage areas so it will switch back and forth between them periodically, including a tunnel where ALL service is temporarily lost.
I noticed that when going through a small area where there is no data coverage at all(this is typical), that when I got back into a coverage area that I had complete LOS! Toggling airplane mode brought data back but to regain cell service I had to reboot my phone.
This is, again, after 2 months with virtually no LOS, travelling the same route every day. One instance is not a reason to panic but having it the first day of using a kernel that's supposed to reduce LOS has me a little concerned.
Now to the point of my babbling. What I want to know is if I would be able to put Bubby's kernel back onto my phone and still have it be compatible with the CWM5 that was installed via chris's lostkernel package?
Thanks in advance for any help.
The kernel consists of a linux kernel + an initramfs (which is basically an initial filesystem but mapped to cache memory, so technically part of the kernel)
On Samsung, the same kernel+initramfs is used for both Android and Recovery.
kernal+initramfs is what people around here call a zImage. When you flash a kernel/zImage, you get whatever recovery came in the initramfs of that kernel/zImage.
So CWM is not necessarily tied to a particular version of the kernel, you can match different versions of CWM with different kernels. However kernels (as the term is used for Samsung phones) do come bundled with a particular recovery, so you flash the kernel you get that recovery, whether that be stock or some version of CWM.
CWM/kernel
Heya.
Lostkernel is from source. Thus it will reduce your LOS but notget rid of it. Sofar for me the only kernel with CWM that is from a stock pulled kernel that has no LOS so far for me is chris41g pulled/CWM. Sorry for not adding link but just look in development and you should see it.
Also this is the Dev.section,you should post your questions in Q&A.
Hope this helps ya.

Apologies for wrong section, I guess since I thought it was dev related it was appropriate, duly noted for future reference and mods feel free to move if necessary.

yes that's it. Are u on ek02 or eg30? U could still use ek02 so yes that is the stock kernel with cwm. U can also over clock the stock kernel with an app called tegrak. It is a paid app in the market. I highly recommend it for overclocking stock kernels.

maybe i missed it but why do kernels have to overwrite recovery?
just seems like recovery should be untouched by anything except flashing a stock kernel or another recovery.
Yes thats the link.
He also has the same kernel with ACS recovery, I highly recomend the ACS recovery, there are a couple extra goodies in it such as pre ROM flash wipe and pre theme flash wipe,but has the same functions as CWM recovery.
Hey but as you can see I still have no thanks yet, even though every post I have done has been ta answer questions that I have had myself and read many posts to find a answer or solution.
So If I did help ya plz hit the thanks button. Sorry tasound soo desperate for a thanks but just one would make my year.LOL.

you got a thanks from me for being the first to recommend ACS5 recovery..
Hey thanks Chris I luv ACS stuff. The best on XDA for the et4g.
Thanks for the responses all, certainly clears things up and gives me solace that I can swap kernels if needed.
To clarify, do I need to install the EK02 update before I flash the EK02 kernel?
Also, the EK02 update is not released yet, correct?

It's a Samsung architecture thing - kernels don't overwrite recovery, they INCLUDE recovery within the initramfs. Change the initramfs, you change the included recovery.
On other devices (including Snapdragon-based Samsungs and Tegra-based Samsungs), there is a separate recovery partition/image that has its own kernel, but not Exynos/Hummingbird based devices.

Nobody is 'ok', if you read the first few posts, you'll see that I get 'reprimanded' point made, and taken. Now besides that does that mean that the thread can't be responded to and the help given? Does that make the thread non worthy of a response? I'd move it if I could. Should I go create the same thread in Q&A and start over?

I can't believe more people aren't recommending it. Anyhow, got a thanks from me for the same reason. Chris, I am wondering if people are hesitating because they think they wont get the same performance as they do on your stock repacked with CWM5. The performance is as good with the great recovery

EK02 modem/kernel
No youdo not have to flash the EK02 update to flash the kernel. You can flash the kernel first. Actually you can flash in any order. Kernel/modem/update. I sofar have EK02 kernel and modem installed but have not flashed the ROM update yet.
Also this is not a official release from sammy yet. But have it from good sources that this will be the final build they will release soon.

I would go to the dev section and read ALL the Sticky threads thoroughly, then use sfhub's auto root in case you're not rooted to gain ROOT. Then I would go with a tw rom like calkulin's Fe22, or if its themes you like you could go with wicked sensations from dazed and confused (team venum) or any of the team rejects roms. Just please read the stickies like 5 times.

I am not a dev at all just a flash junkie. I would read up on "FULL RESTORE ROOTED EL29" you can search the for the forum in the development section. Check out all of the roms and just ask questions. One you are rooted its pretty simple if you follow directions well. I'm running Dazed and Confused romantic now but I switched between him and Mijjz roms like his Goodness rom, he has a ton of roms and all of these are themed already.

I mean Dazed and Confused rom not romantic. If you have any more questions just ask man. Good luck and have fun. Just remember to read and follow directions
Just a tip
I would also recommend watching some of QBKing77's youtube videos as well if you have never flashed a Rom before. He pretty much goes step by step through the entire process. He has videos that show you how to root, how to install clockwork mod and then videos on how to install many of the Roms that you will find in the development section as well as reviews for each. QBKing77 was pretty much invaluable to me when I was getting started myself. Thanks to him and following the advice to read through the development section over and over before I started I've stayed brick free and flashed most of the ICS Roms safely.
Hi all, I just came over from Motorola and must say this is a sweet phone. This phone came with 4.0.4 on it which seems nice. Anyway with my Motorola I had to unlock my bootloader, any need for that here? Any info on root and installing roms would deffinently be appreciated.

There is a lot to be found if you look through the threads.
I found this WIKI to be of great help.
http://forum.xda-developers.com/wiki/Samsung_Epic_4G_Touch
You can find a list of ROM's available for the phone included with a link to the thread on them where even more information can be found such as battery life, specs, kernels, and modems that are compatible with the ROM.
Also look at:

Personally I went back to Stock Rooted EL29 and am running Calkulins E4GT ROM which is fantastic in both liability and battery life. That can be found here:

If you decide to go back. Just my opinion. If you want to stay on ICS then here is a ROM that a lot of people have had success with it looks like.
http://forum.xda-developers.com/showthread.php?t=1363071
That is for rooted 4.0.4
Here is another great article to read.

Hi guys, I'm new to the android world here, and so far I'm loving every minute of it...so far I have learned how to root my s3 (yay me!!) and also installed a few ROM's here and there. I came across this Team-Venum Wicked Sensations v1.0 SGH-i747 which I really wanna check out but, I have a quick question. Do I have to install the "Kuban updater fix", and if yes, do I have to reboot when thats done or can I go ahead and install the ROM then reboot?

Hi. i have been watching that thread also to try it out. Looks like there are a few little issues they may have worked out so Im just waiting to see. The updater I believe is how you can update the ROM and customize it. I dont think its "needed" but looks like it would be a great benefit. Again I did not flash this ROM yet but what I would do is first just flash the ROM and then reboot. Make sure it boots and everything works. If that's all good then I would flash the updater.
Ok thanks man

Hi guys. I know this is probably a stupid question, but I would love to get a recovery on my phone. I'm coming from the evo3d which as super easy to work with. Right more I'm on fk23 I believe it's called through Odin. Really want to try cm10
Sent from my SPH-D710 using xda app-developers app
Get mobile odin and flash the el 26 kernel. Really simple
Before you boot cm 10 don't forget to flash an ics or gb modem first in the same time of flashing the Rom
Sent from my SPH-D710 using xda app-developers app
Best thing to to would be to read the stickies and how tos. And then read them again. Improperly rooting and addding a custom kernel (Recovery is part of the kernel on this phone!) can brick your device!
Not saying this to be a smart ass. Really it's that important; read the stickies, wikis and how tos. And once you've done that you will surely enjoy this phone.
Then read through the ROM OP you wish to put on your phone and read the the following posts - all of them.
You will save a whole lot of frustration and get 99% of your questions answered before you go and ask.
You don't quite say how you got to FK23 and what version - I assume you used PC Odin and via the One-Click Stock Rooted method. If that's the case you can, as the previous poster suggested get Mobile Odin (via playstore - my recommendation to support the dev, or go to the devs post and download the xda only app and kernel part there) and flash the EL26 CWM kernel that way. Or you could even use the One-Click Kernel method rwilco12 has them all here http://forum.xda-developers.com/showthread.php?t=1662295 or the 'Direct boot to safe recovery - CM team has info here http://e4gtcm.blogspot.com/p/cm9-install-guide.html
Either way, and espeically with Cyanogen builds follow the install directions - EXACTLY or you'll be making an expensive paperweight.
Good luck have fun.

Cool, thanks for the quick replies guys! I saw a FK23 packed with AGAT recovery floating somewhere, my question was, if I flash that with Odin, is that firmware compatible with cm10? Or Miuiv4.1? Or any rom for that matter if it doesn't specifically say built on fk23?
And so only the ICS kernel will work on those roms, eventhough they are JB? I thought I read somewhere that modems and kernels werent backwards compatible. Appreciate the quick responses, I'm not a total noob I've flashed and rooted lot of other phones, just got these phones in the mail wednesday though.
DO NOT use the TW kernel repacks on CM builds. That is a brick waiting to happen.
Modems that is another story. JB modems are needed for JB TW builds but some have been able to use older ones, most notebly on the AOSP ROMs.
My best advice stands read through the OP of the ROM you are wishing to use then read through the entire followup posts. The CM team golks suggests EL29 direct boot or EL26 'safe recovery' and then using the kernel supplied by the ROM - CM10 kernel. The Miui also has the same explicit instructions. I'd heed them. But the choice is yours
search is your friend.
Thank you leaderbuilder, I almost bricked my wife's phone twice. I got it fixed, but I just asked in another thread on some advice on what to study up on & I click here & read your post. Heading off to the stickies am I. Thanks again.
