Is there any way to get CWM on this phone without compiling a custom kernel based on the source? At this point it seems obvious that the LOS issues are caused/increased when replacing the stock kernel.
I am coming from an EVO and I don't believe CWM needed to be included in a kernel to be installed. Is it different with this phone?

have you looked into this?

From my understanding....and I'm not a developer I don't think so. The Kernel has to be recompiled to add CWM and you need thave access to source code to be able to do it. I don't think you can just pull the stock kernel from the phone and add CWM it...don't think it's that simple.
The Captivate has a solution where they can go into regular recovery and run an update.zip to get into CWM recovery. The CWM recovery isnt permanent in this case, it is loaded into RAM each time. I wonder if something like this could work for us?
Sent from my SPH-D710 using Tapatalk
what i do each time is flash the kernal that has CWM.. make my backup of the rom or flash whatever zip i need to flash.. then i flash back to the stock kernal.
Yeah I never understood that, coming from the Evo, Evo 3D, and Nexus S 4G. On those phones, or at least the Evo and 3D, recovery has its own kernel (usually built of the AOSP kernel), and has nothing to do with the kernel on the phone. So why does it work differently on Samsung phones?

Original epic was the same way. We could flash recovery to the stock kernel. This phone is different supposidly.

Hello
I have a Samsung Tablet 10.1 and I remember using Odin and pushing a file to the Tablet, the files were SU binary and maybe the SU app, that's it
I liked what I did because I have pretty much the original tablet with original Kernel, I only "pushed" the SU files
However, with the Samsung Galaxy S II (Sprint Epic 4G Touch), the only root that I found involves changing the kernel
Any way to do it WITHOUT changing the stock kernel?

You can always flash the stock kernel pulled from a nonrooted device and have complete stock but root.
I did this with the tar file from acs pulled from a nonrooted phone....

These are root with no kernel. The former is deodexed if you want to install any mods, the later is stock.

curious why you'd like to have the stock kernel intact after root. is there a benefit to this? i'm coming from an EVO 4G where it seems where the modded kernels were almost always better than the stock kernel.

There's a vocal group of people that seem to insist that the loss of service (LOS) bug is not affected by the kernel. Most of their evidence seems to be that people get hit by the LOS bug even on full stock.
However, the LOS bug seems to hit people on stock once a week, if that. I've never seen it and I've had the phone since launch day, which is about a month now.
The LOS bug seems to hit people on custom kernels as much as multiple times a day.

AFAIK, the kernel and recovery on the E4GT are flashed to the same partition so if you can't flash one without the other.
Damn this must be the first phone I have ownd with that

Odin is a program used to flash recoveries/kernels, roms (usually just stock roms), and modems. There's an open source alternative called Heimdall that works well too. you can purchase Mobile Odin from the Play Store if you want to flash kernels directly from your phone. This makes it convenient when you cant or dont feel like using Odin on your computer to flash a new recovery onto your phone. ALWAYS USE **PDA** SLOT FOR RECOVERIES/KERNELS/ROMS. ALWAYS USE **PHONE** SLOT FOR MODEMS. Odin/Heimdall DO NOT flash .zip files. They only flash .tar files (kernels/roms) and .bin files (modems). Again, ALWAYS USE **PDA** SLOT FOR RECOVERIES/KERNELS/ROMS. ALWAYS USE **PHONE** SLOT FOR MODEMS.
Modem is the radio. Kernel versions dont have to match the modem version. You can be on kernel EL29 but still have a modem of FD16, and vise versa. Some people have better luck with the latest modems, some people have better luck with older modems. Your mileage may vary.
As for recoveries, they are always (always) packaged and flashed with a kernel. This is how Samsung does business (at least on most of their phones). Some kernels include a custom recovery, others dont. As of now, no ICS kernel comes with a custom recovery (actually this statement might not be accurate now that i think about it). Whenever you flash an ICS rom (which comes prepackaged with a kernel), you will always lose your recovery. No bigs, just Odin a kernel (ALWAYS USE **PDA** SLOT FOR KERNELS/ROMS. ALWAYS USE **PHONE** SLOT FOR MODEMS.) that includes a custom recovery (the most popular one is EL26 with CMW [search for it]). Most roms you encounter will be flashed through Recovery. If it's a .zip file, it's flashed in Recovery.
"Currently stock rooted" means you're on a stock rom that's rooted.
"EL29" most likely refers to the kernel that is packaged in the rom, but it can refer to your modem version too. The first letter represents the year; the second letter represents the month; the number represents the date of the month the kernel/modem was built.
E = year (2011)
L = month (December)
29 = date (29th, hurrrrrr)
So if someone's modem is FD19, that means:
F = 2012
D = April
19 = 19th
All ICS kernels begin with F because all ICS kernels were leaked/released in 2012. All GB kernels begin with E because they were all released in 2011.
The last stock rom/OTA released by Samsung was EL29. There have been some Samsung ICS leaks however; they range from FB## - FD##.

Ok. So if I want to flash Calkulin's rom. Download the rom and radio. Use odin (mobile odin) to flash them.
What about recovery? I didnt see it mentioned.
EDIT: I see it says I need custom recovery to flash. So would I just odin a kernel that has recovery already?

Both roms tell you what recovery they come with, and tells you that you need to flash them through recovery.
Edit: Yep, just Odin a kernel that has a custom recovery.
So rogue kernel. Would that be the rogue recovery?
So which kernel should I use to odin on just stock EL29 that has recovery?
EDIT: Or....the kernel (with recovery) and rom pack into the zip?

Yep, they come with Rogue Recovery. You can Odin EL26 with CWM and that will give you CWM so that you can flash those ROMs.

No prob. Also, a HUGE thing to remember...
Just stick with EL26 or EL29 (GB) recovery. Using an ICS recovery (anything beginning with "F") can lead to you permanently bricking your phone. People have been successful using ICS recoveries, but lots of people have also hard bricked their phones using them (me included). Very very very very few people (if any, I cant recall any) have bricked their phones using GB Recoveries.

I do realize we can switch between radios and they don't necessarily have to match the rom. I think iylt just goes against how I thought it went together. I have ane evo 3d as well as this phone and that is not the case with that phone. In fact when I am on a later radio with an earlier build rom everything messes up and force closes are everywhere. Just wondering why we are able to upgrade the radio with "no" problems when that modem was built to use a different build. Not to mention its not even the same version ie gb rom and ice cream modem. Any thoughts on this subject?

modem's should have zero interactions with apps in a way that can cause them to force close. are you sure you're not confusing modems with kernels?
I've read through most of these threads an I'm pretty sure there is no CWM for ICS for the Epic 4G Touch. Is this correct?
I have the s2 for tmobile and it is practically unbrickable compared to this phone. My friend has the Epic and I installed ICS AOKP. It is way more difficult on his phone. I don't understand why it is so different. Given, we have different hardware, but neither one of us have the source for ICS or kernel. But I do have the same CWM no matter what rom I'm on.
1. Is it possible to have CWM on the Epic 4G Touch?
2. His ext_sdcard is not showing up. How to I make it work? I tried DirectoryBind to no avail. Maybe I'm doing something wrong.
3. Can i flash zips in ICS recovery? Ive never seen the recovery it put me in before.
4. Am I missing something?
I was under time costraints when helping him out and honestly I'm just happy i got AOKP running on his phone without any issues.
I appreciate all the work everyone has done so please don't take anything I said the wrong way.
Thanks in advance an i look firward to hearing from anyone...

We need ICS kernel source before we can have a proper CWM kernel for ICS.
Sent from my SPH-D710 using XDA
We had CWM on ICS for a little bit, but it was causinga ton of bricks because the partitions are handled differently in ICS. I wouldn't attempt to flash anything in ICS recovery because you risk bricking the device. We likely won't have CWM for it until kernel source drops.
If you need to flash something, the best way to do it is to Odin back to EL26, install CWM, and flash everything (ROM, kernel, modem etc.) in one recovery session. Most of the threads for AOSP ICS roms have specific flashing instructions in the first post.

Well recovery is packed into the kernel, you can not use the same kernel for both operating systems lol. The phone simply will not boot a GB kernel (linux kernel 2.6.x) with an ICS Kernel (linux kernel3.0.x).
For flashing from ICS i am on CM9 so i just use the safe recovery thats been in the nightlies for awhile, alpha6 as well. TWRP is available for both TW and AOSP i believe. Agat's recovery is available for TW etc.
I think the question you should have asked is which ICS recoveries are safe? Keep in mind a zip with an unsafe updater binary is not safe on a safe recovery except those like TWRP that replace the updater binary when flashing.
Thanks, I'm learning a lot the last week this is def cool learning all of this. Thanks. I didn't realize the kernel was part of the recovery. I come from the Evo 4G and things were really much simpler.
Sent from my SPH-D710 using Tapatalk 2
Yeah the recovery is packed in the initramfs of the kernel on our phone.
I won't say yes but, Agat recovery had allowed me to backup, restore, flash ICS to ICS and even wipe. i am not going to mislead you but it had worked for me everytime. I hard bricked using other recoveries in ICS. Agat is my recovery of choice. I would wait if not confident... Word on the street is that source code is out.

Not to nitpick but I think you meant you can't boot a GB ROM(not kernel) with a ICS kernel or a ICS ROM with a GB kernel. And also you can, I've seen 2.6.x kernels booting ICS frameworks, it just requires some mods.

The CM9 ROM has all EMMC erases disabled so it is technically "safe". And I believe that there are a few instances where TWRP doesn't manage to replace the update-binary.
