[Q] Stock kernel (FC14) / Rogue kernel (FC07) for ICS - Samsung Epic 4G Touch

First of based off my post count you can tell that I am new to this so please be kind.
On the Blend ICS thread I have seen (can't post there yet, that's why I am posting here) several people state that it is best to run FC14 on the stock FC14 kernel, but that kernel does not include CWM so in order for me to update to a new ROM I would need to flash back (Odin) to a kernel that does include CWM. Please correct me if I'm wrong...
So, to get off of the stock kernel (no CWM) should I use the [KERNEL/RECOVERY][ICS] Rogue *Stock FC07* (New 3/10/12) kernel for this? Sorry if this is noobish, I only ask because in that thread it states:
Warning-
***DO NOT USE THIS RECOVERY TO FLASH ANY ROM***

so, I don't want to brick my phone and thought that I should ask before I use it.

Welcome!
You'll probably want to read over this thread as it should answer your questions about the brick concerns:
How Not To Brick Your E4GT

Thanks for the welcome, and also thanks for the response.
I guess my specific question is what are they (e.g. bigtoysrock) using as the kernel with CWM support when flashing using Odin so that they can flash a new ROM?

Got your PM. I use This FB21 tar to get recovery back. Personally I dont use the FC07 one, just cause I have the FB21 already.

Thanks so much for your response!

[Q] Are kernels bound to specific versions of CWM?

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.

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.

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?

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

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.

Flashing to ICS from rooted EL29

Hello all:
I'm a noob here so forgive me if I've missed something somewhere else.
I am on a stock EL29 rom and I'm rooted. I haven't done the ICS OTA update, but I would like to try ICS. The OTA notification keeps bugging the **** out of me. So, Here are my questions:
1) How do I flash ICS on a rooted GB EL29? Do I have to unroot first and then do the OTA update? If not, what and where are the correct procedures?
2) When I boot to CWM, it shows a Team Rouge logo and the menus aren't exactly the same as the menus I see in various demo videos. How can I get a "stock" CWM and flash it over the Team Rouge CWM? I downloaded ROM Manager and tried that, but the phone still boots to the Team rouge CWM.
3) Should I just forget flashing ICS altogether and just flash a new ROM/Theme on EL29 instead? If so...what's a great ROM to flash?
4) Any other suggestions y'all might have
I have Android version 2.3.6
Baseband version S.D710.10.S.EL29
Kernel Version: 2.6.35.7-SPH-D710.EL29-CL852097
Build Number: GINGERBREAD.EL29
Hardware Version: D710.010
Thanks in advance....

Ok so do you want ics rooted? If so you can find a one click in the stickies and if not and you just want the ota you will have to unroot because you can not have a custom recovery and update ota

Yes, I want ICS rooted. But if I do the one click, can I do it over top of a rooted EL29? I've also heard that I have to have a certain CWM to do the flash to ICS. Is that true?
I also want the ability to back the other way.
I'm just really worried about bricking the phone....I've read enough on here to be abundantly cautious....
Just do the one click and then flash agats kernal via computer after(QBking77 has a video on YouTube showing how to do it).

You can flash a direct boot cwm from mobile odin that is safe. Then from there flash whatever ics rom you want. No emmc brick risk.... also that will keep the yellow triangle off if its not there already

If u wanted to go back you could do the mobile odin flash then restore the nandroid.

I would even say give the JB AOSP a run. Battery life is great, has a couple cyamogenmod components, and is really really smooth. Last build today really made this phone a daily driver for me. Flash the same as ICS cyanogemod but make sure to flash jellybean gapps right after the ROM.

Thanks Dante...I was reading about that Rom earlier. From what I've heard, the battery life sucks on the stock ICS, so if this one has great battery life, that definitely would go a long way to recommend this rom.
Thanks again!
CM9 battery life is great. I havnt tried that AOSP JB but I haven't found one that was stable enough for a daily driver... I'll wait a month or two before JB on the e4gt.

Best AOSP Rom?

Hi, I am not new to rooting and custom ROMs but it has been a while and the forum has so many roms that it is hard to decide which is the most stable.
Would you guys please recommend to me the best/most stable/most customizable(cyanogen) AOSP rom for this phone? Basically I'd want the best CM9 rom and hopefully CM10 once its stable.

1. I believe the difference between the to sections is that Original development is for AOSP based roms while android development is for roms based of stock or leaked firmware. That being said i dont think that many people understand that when they post and it has been kind of a Cluster f.
2. Are you currently on the OTA? you will need to odin a kernel that has a working recovery with it. If youre going to another rom right away it may be easiest to odin EL26 cwm, then load into recovery and flash because this will install the kernel/recovery packaged in the rom.
3. Ive used AOKP some and its pretty nice but i am one that likes to stay with a rom that still has activity. That way if i have problem there may be a chance that it is going to get fixed. But if you are ok with a few problems here and there go ahead and test out CM10 or sbrissens AOSP.

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.

What TW ROM should I install and NOT mess up the EFS?

Hi guys.
The title pretty much says it all.
I currently have the XXDME4 modem installed (went to this from XXDLJ2 and... I have no idea what modem I was using prior to that) and am using Slim Bean ROM. But, I want to give a TouchWiz ROM a try, to test something sound related (5 minutes), then be done with it and return to AOSP based ROMs and such. With all this modem/EFS talk... I am very confused. Don't know what modem/ROM base I am safe to go to now...
So. What TouchWiz ROM should I install and be free of any EFS ****ed up things?
Thanks in advance!
If u r happy with this modem, install a rom like assasin which gives you option whether to keep the old modem and kernal or to change it. If you dont change the modem, efs wont be messed up I fee

Ya. If you lose your EFS anytime at all, Revert back to XXDME4 and restore this image.
There is no other easy ways than this. This would just take seconds and you're already rooted.
As mentioned by people before, you're fine as long as the ROMs you're flashing doesn't mess up with modem.

That's what I initially wanted to find out : what ROMs out there don't do that... :laugh:

That's easy, download any rom, enter the archive with some Zip tool and replace the modem part with your current one. Or if you feel up to it, edit installation script to not flash modem. You can do the same with kernel so it is not flashed at all. That way you can use any rom without fear
Most roms are in fact compatible with wide variety of kernels / modems (even if some are included in installation - they are tested by developer to be fully compatible) so you should have no problems. For your information you can currently use all roms that are from ME6, MF2 and MG1 family - as Adam's kernel author mentioned, the compatibility problem lies in changed kernel ramdisk and he uses old one so you can flash his kernel over any TW rom without fear of breaking EFS.

Yeah...
Ok. So, as I now am on XXDME4, what other modems am I safe to go to? DME1, DMF2, DMG1...? Anything, EXCEPT for DME6?!

Anything before dme6. Dmf2 and dmg1 are after so not safe if you don't want the efs headaches.

F***. Now I don't know what's after and what's before. Can you please tell me what's before...?
It's hard because even in the modem thread, there is not a list with all modems in chronological order...

Samsung version naming is alphabetical followed by a hexadecimal suffix. Bmf1 is older than dmb2 which is older than dmb5 which is older than dmc3.

I... I'm not good with hexa stuff... At all...
Can you please list me the modems/bases older than DME4 that are safe?

It's easy: rom names are created from years and months and inmonth revisions
so LL7 is revision 7 of December 2012 rom
A-January
B-February
C-March
D-April
E-May
F-June
G-July
and so on...
also
A-2001
B-2002

So anything before ME1 is really safe. Best would be to flash stock for example XXDMC2 and on that flash any new custom rom with modem and kernel flashing disabled.
Oh... I think I understand...

I'll try finding a custom ROM DMC.

But hang on a second. What if I flash a new modem? I do not intend to stick to TW - I just wanna test something sound related cause NO ONE ELSE WOULD then go back to Slim/CM etc.
If I use the very latest modem (whichever that may be) and use them on CM... Would there be a problem?

Not from CM side CM mostly does not care what version of modem you have, and it's not the modem that is creating all those problems, but newer kernels (ME6 and newer). So don't touch the modem at all or flash it if you want. But don't flash newer kernel ME6, MF1 or MG1. Flash Perseus 36.3 kernel, do it immediately after flashing rom, without restarting recovery, because once you run new kernel even one time you have a problem.

So... I can flash a ME6 ROM but not boot it, and flash this older modem again + Perseus THEN reboot and I'll be safe?
