Best way to get ROOT and keep stock kernel? - Samsung Epic 4G Touch

Hey guys. I actually don't even have this phone yet but will be getting it shortly. I definitely want to root it (I have a rooted EVO 4G and Xoom tablet) I'm a little confused though about the different methods I'm seeing.
My goal is to obtain a fully rooted phone w/ stock everything. What is the best method to do this?

ODIN this and you will get CWM, root, Ive found the LOStkernel to be a lot better than stock.

Sorry for the noob question but when I watch Qbking's video on this kernel he says you need to be rooted and have CWM installed to flash the kernel. But what you're saying is this kernel can provide root, add CWM and flash the kernel if you use Odin to do it? If so, I'm right in saying I'd want to download the TAR file rather than the ZIP? For root, would I need to flash SuperUser via CWM or is it built into the kernel?
I've been thinking about jumping into root soon to try out the Starburst ROM and I've evaluating the cleanest way to gain Root + CWM. I was thinking about using Bubby's method, but this seems solid too if my assumptions above are correct. This would be my first Android root by the way so I'm being patient and extra careful.

I just got this phone recently and rooted it.

thats a really good place to start. but to be honest every time you use odin and you flash a kernal in odin you'll get an annoying Yellow triangle that pops up in the beggining. So Your best bet is to flash to a kernal to gain root then flash the kernal from the unroot tutorial as if your unrooting the phone it wont remove superuser.apk automatically, and it will remove the yellow triangle, then from that point just use either cwm or the zimage flasher from adb to do it.
My recommended steps are
this one first for gaining root

then this one
http://www.youtube.com/watch?v=ySskTt-S-cM
Follow links in youtube description.
after you do that, don't use odin anymore just use cwm and that adb script for changing kernals and you'll never get that annoying triangle again.
Also be aware that everytime you flash with odin the phones bootloader records that you flashed it, meaning even if you take it back to stock if sprint wants to look at it for warranty purposes they can still see that you did something to it. which means that youll need a $2 jig to wipe that count which I don't even know where that is.
If you can use a temp root thats used for 2.3 gingerbread on other devices then use second link in youtube to avoid using odin, I kinda wished I knew before because then I would have done some more experimenting with the phone. so annoying, I have control of this device and at the same time not which really sucks!
Edit BTW: Why use the starburst rom it doesnt really look that snazy to me for me to consider jumping to it the stock one works great why not just flash a deodex stock one and flash a theme to it, theres some really sick themes in the theme section of xda check it out! XD

I had some wake lag (about 2 second delay between pressing the power button and screen turning on) with the LoStKernel, so I've been running this:
http://forum.xda-developers.com/showthread.php?t=1284511
It's been working well for me so far. You'll have to get root access first, so try out the LoStKernel to gain root access and if you don't like it switch to this.

[Q] Few questions about root and cwm3

I have read through this forum and I am still unclear about a few things. First off I have a vibrant and have been flashing roms/themes, ect. I just got a epic 4g and get things straight before flashing.
1. The epic is completely stock, can i just use z4 root then flash cwm from rom manager on market? Or do I need a different kernel first? If I do need a new kernel, could I just use one of the kernel flashers on the market like SGS Flasher so I do not need to use odin?
Every thread I have seen has been mentioning using odin for the root/cwm 3 process. I have a macbook pro and my desktop pc is ancient so I try to avoid using odin whenever possible.
2. Just to confirm, is it really hard to actually brick this phone? I have messed around with my Vibrant, soft bricking it a few times but never had a problem restoring a stock rom.
3. Once rooted and cwm mod flashed I can go to any rom right?
Thanks and I know there are very similar questions already posted, I just wanted to be 100% clear because some answers were really vague.
You can use z4root but you can't install cwm with rom manager on stock kernel. It is really hard to brick the epic and yes once rooted with cwm you can get to flashing. Odin is used just to flash stock roms. I used it to flash the dk28 froyo rom and I only use it if I have to. Try to get your hands on a windows computer to root it with cwm. You can run the root plus cwm that is stickied in the development section. Once that is done you are ready to go. Good luck
Im in the exact same boat dude. I've had mine for about 4 days and still haven't done anything else but update to DK28. I did the z4root first, then thee next day I did the update. Now my SU doesn't work and I can't unroot using z4root. Phone just starts to vibrate and then I get a FC. I dunno, going to have to odin once I get some time. Really diggin my epic, but the vibrant was so simple and fun.

While you may be able to use z4root to to root your phone, like musclehead84, I am under the impression that you can't install CWM through Rom Manager on the stock kernel (LINK supporting this, I may be wrong though). It may work with other kernels, but to flash those kernels, you need CWM... kind of a Catch 22. Not sure if SGS Flasher will work for flashing a new kernel, but if I recall correctly, I remember reading atleast one thread resulting the need for a restore after using SGS Flasher (Odin or Nandroid, can't remember which).
And your not using Odin for root/CWM, your using adb (included with the one click root and CWM download), which I believe can be run from the terminal on a Mac with the right adb version ('one click' OSX LINK using older joey-krim root method, but if your flashing a new pre-rooted rom anyway, will work fine).
2. Just to confirm, is it really hard to actually brick this phone? I have messed around with my Vibrant, soft bricking it a few times but never had a problem restoring a stock rom.

Yes, it is fairly hard to actually brick the Epic. If you have issues flashing your phone with Odin, the most likely culprit will be the usb cable. I have also read others having luck with removing the micro sd card before flashing, or even booting into download mode (which is done by holding '1' on the keyboard while pressing the power button) while leaving the battery removed.
3. Once rooted and cwm mod flashed I can go to any rom right?

Yes, with a couple caveat's... If your flashing a froyo rom, you will need to make sure you also atleast update the modem to the proper one (i.e. DK28) using Odin, or flash the leaked 'official' beta update.zip while on a stock DI18 to take you to DK28 with modem, (LINK with instructions, would do this before bothering to root or anything though). And if you decide to convert to EXT4 (DK28 only), that's a whole other story.

trouble less root

i'm trying to install some apps that require root. im looking fotr the least intrusive way of doing so, with zero side effects. tried reading thru the forum, but got confused. can anyone please point me in the right direction. thanks
If your looking for just root on stock kernel I would wait. It will come really soon. If u want it now then u need to flash zedos v3 kernel and then flash the stock kernel back. Then u will have root on stock kernel. There should be a root + cwm stock kernel be coming out soon though thats why I said to wait.

1) Flash ACS CWM recovery in odin. http://forum.xda-developers.com/showthread.php?t=1268037
2) Flash su zip from the same post in the recovery.
3) Flash ACS stock kernel/recovery in odin. http://forum.xda-developers.com/showthread.php?t=1273647
This method only adds root binary/app while leaving everything else stock.

[Q] Best suggested method for root and recover?

I haven't updated my phone yet it is still running EG30 so that might be useful. I'm wanted to root and install a recovery but I'm kinda worried about these modems and kernels not being compatible with each other and all the people bricking their phones. So my question is how should I go about rooting this and getting a custom recovery so I can flash Caulks or CM7 on this?
I've never used ODIN I don't really like the idea of having to plug my phone into a computer everytime I want to flash something but if it's the best way to root then so be it.
If you search the threads or go to youtube there is a guy by the name of qbking77 who would give you step by step guides on rooting device ave guides for flashing different things for your device
I've been watching his video's. I was thinking about doing the auto root but I don't know which kernel/cwm to flash I think is my problem. Do we have a way to root the newest update? Should I just update and root from there and then apply the newest kernel and cwm?
I'm coming from a EVO 4G so this isn't what I'm used to exactly.
If I flash a new el26(?) kernel and still have the old modem won't I run into problems? I'm a bit confused about this whole set up and how it relates to the roms instead. I know on the evo the Radio and Kernel sometimes ran into conflicts but it was simple to flash a new Kernel or Radio then re-flash a rom to fix it.
Well to be honest im not to sure im just stock rooted when u update you still can root the phone, all I did was just update my modem to ek02 to match the update, that's what the update put you on is ek02, im not really into flashing roms and things like that
I rooted my phone through Odin with El13. I like the Odin method and you only have to do it once to gain root access. Since then I flashed a different kernal and changed to SL26 through CWM. What I would recommend is finding a QBking77 rooting method on YouTube and its that easy. Once its rooted you can flash different kernals, modems, and roms through CWM that work best for your phone. QBking77 videos make it really easy to understand.

Follow this video to obtain root: http://www.youtube.com/watch?v=Be2evusAwOM
Then...
Follow this video to install cwm recovery: http://www.youtube.com/watch?v=jZRnH-_XZmM
That is what I did and its a good way to gain root and cwm. Don't forget to click thanks for sfhub for his auto root script.

Maybe a dumb question....

Ok, so I have rooted my Epic Touch strictly using odin. I downloaded the stock ics tar that was already rooted. It did not however, include CWM for adding custom ROMs. I would I would like to know if i can put the CWM in and not mess up root or should I unroot and do the root a different way so CWM is included? I just dont want to brick my phone. I would like to play with different ROMs but not brick my phone.
Thanks in advance. Hope I stated what I am trying to do correctly.

Easiest way to add a kernel with CWM would be just using the old auto rooter. Option C and pick whatever firmware you have. So EL29 + CWM is L - http://forum.xda-developers.com/showthread.php?t=1342728
Just read the instructions. Goto settings > applications > developer options and tick the usb debugging and then connect the usb cable.
To help you understand odin and how you rooted your phone I will say this. When you used ODIN as the method to root your phone, and if you were on EL29 it was the only way to. What happened is you actually reflashed the firmware with a copy that was rooted. As long as you dont install a rom that for some reason doesn't have root which would be sorta odd or ODIN a tar over thats not rooted (or use a non rooted one click) you likely won't lose root. Unless you really wanted to
ODIN can also be used to flash parts of firmware such as the modem or a kernel etc. But as for your root someone rooted a rom repackaged it for flashing with ODIN.
Thank you!! Worked like a charm... Now to remember how to launch into CWM again lol....
Power the phone down, then hold volume up and power button together until CWM pops up.

I hate to be a killjoy but I'm pretty sure you stated that you're using ICS?
I wouldn't recommend using CWM in ICS. Even seasoned developers have turned their phones into paperweights because of issues with ICS and recovery.
If you want to see what ICS is like that's fine. However, if you're new and want to play around with ROMS that support recovery, you should ODIN back to Gingerbread.
There are a TON of threads here concerning issues with ICS and recovery that have had fatal consequences to the owners' phone.

Root Problems FF18 ICS

I need a little help here.
I rooted my phone when I was in EL29. Everything worked nice and was fine, but then I ran the official update to ICS FF18. I didn't even realize there was a problem until I tried to under clock to save battery. It said root access was not granted, I downloaded root checker and it confirmed that I don't have root.
Super User is still installed but has no real function. I would like to know how to reroot without harming my phone.
I was also wondering about Clockwork recovery and installing different roms, my Android OS uses 60% of my battery and I'd like to have something a little more light weight. I tried flashing my recovery with Rom Manager but it does not have my model under devices.
Any help would be appreciated.
Dude, sounds like you just gotta read a little more(annoying answer I know).
If you ran the official update that's not rooted, you'd have to do either sfhubs one click official rooted's, or flash a custom rom through recovery. And also, Never use rom manager for anything, its not set up for our phones, so you don't want to use it to get temp recovery. You can use Odin to flash a kernel with recovery onto a stock setup to get you started, then flash either a custom rom, or one of the many stock rooted options in the dev section.

Ok, that makes sense. I was just worried that if I tried to root it and it was already rooted that I would brick or something. I'm pretty sure I can handle it now knowing that I just have to root and flash like usual.
Is there a "best" rom for the E4GT or is it just based on preference?
Root here:

Then go here, use option D for cwm.

As sleshepic states, stay away from Rom Manager (for E4GT, anyway...). If you're having battery issues, you can use a battery conservation app. You can also underclock (or auto-underclock when phone usage is low) with Set CPU.
