[Q] Few questions about root and cwm3 - Epic 4G Q&A, Help & Troubleshooting

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.

How to flash modem, pit and or stock rom without using odin or a pc period.

I'm looking for a way to go from stock rom to a custom rom and back to stock without having to use a pc.
It would be cool if all of this could be done through clockworkmod or a version of odin that would run similar to clockworkmod on the phone itself.
Does anyone know a way to do this?
Has anyone heard about a person or an organization that is working on this sort of thing?

Well, i've downloaded ROMs to the Epic while on the go, rooted with z4root, done a CWM backup (before i ever flash a new ROM), booted into recovery, and flashed ROM of choice all without using a computer. I'm not as smart as any of the devs but it seems fairly easy for me this way.
Right now on my microSD card, i have several zipped ROMs on there (stock DI18, DK28, some custom ROMS as well) . I'll bet a lot of folks do the same as well.
There are some things you just can't do without odin.
If you read through the one-click root and recovery .bat file, you should be able to figure out how to root yout phone and install cwm without a computer. Remember to back up the original recovery if you plan on putting it back later without odin. You can then flash around to DI18 roms and get a stock di18 image to go back to.
If you want to mess with froyo, learn to odin.

I'm not sure about that. I ALWAYS keep a stock di18.zip on my sdcard, as a just-in-case. And I also know that noobnls post where I got it from also has a di18 modem in case your coming from a different firmware version...so there should be a dk28.zip and modem.zip right? If so why not?

Also do not post in the thread itself telling the user that he made a mistake or broke a rule as it doesn't contribute to the thread and is unnecessary.
Trying to flash an entire tar without odin or heimdall is dangerous... it is the boot.bin and sbl.bin that are most dangerous to work with... a wrong flash with sbl CAN brick the phone... as in, you can't even get to download mode. The sbl I know is different with Froyo. The other issue is with the modem, but modem flashes have been made that'll work in some cases.

[Q] Help. I accidentally upgraded to CWM3

I have the DRockstar one-click root and I use a Mac. I want to flash the Midnight V5 ROM, and when looking at what version of CWM I was running, I inadvertently updated it to 3.0.1.4. I tried unrooting and rerooting, but I cannot get it to revert back. The Midnight V5 ROM says to use 3.0.0.5/6. The other major problem that I have is that I am running stock DI18 with noobnl Andromeda Galaxy Kernel version 1.4.1 and I can't 3-button boot to CWM now, so I'm scared to flash any ROMs at the present time. I also can't do the new CWM3 root, because I'm not running Froyo. I think I've gotten myself into a pickle. Will Midnight V5 run on the newer version of CWM that I now have? If so, how can I safely flash the ROM, as I can't hard boot to CWM? Another option I considered is doing the Daemon deodexed EB13 flash, then doing the proper CWM3 root, then flashing Midnight V5, but I still come back to the fact I can't boot to CWM unless I use ROM Manager. I basically have a mess, in my mind, and I don't have a deep enough understanding of any of this to know what to do now. Yes, I am a n00b that really could use some good advice/help now. Thanks.

Don't Mac users use Heimdall like we use Odin? And just install the EB13 tar?
Here is a thread to it:

Thanks, but it looks like I would still need a windows machine to fix the bootloader.

Ok, I dusted off the wife's old XP laptop that barely works and had the balls to trust it to not brick my phone. I used ODIN and got the stock EB13 tar loaded and everything is working. Now, I want to do the CWM3 root, but the ghetto computer is so corrupted, it won't run the batch file. Is there a way I can execute this root on my Mac? I tried using the Linux run command from Terminal, but it starts to run and tells me my phone is not connected. This also happened when I tried to run the Noobl 2.5.5 oneclick root. The only root I can get to run on my Mac is the DRockstar oneclick.

Best way to get ROOT and keep stock kernel?

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
http://www.youtube.com/watch?v=kExN-Y2pfxA
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] need some help..

I feel helpless now, sorry ahead of time if someone instantly redirects me to a section of the website. I've been searching forums for almost 5 hours now and have gotten nowhere. I sent my phone in to get the brick fixed and had him root it at the same time... I'm running 2.3.4 kernel version 2.6.35.7 gb.eh17? So i'm assuming this is a stock rom? I have no cwm for my phone, i haven't been able to flash it or install it whatsoever, I get failed signature everytime. Now I understand that 2e as opposed to 3e (which I have) allows unsigned files to be installed, but I haven't been able to find a way to revert back to that.. There's kernels that I can download that come with cwm but those have root files in them too.. will this mess anything up? could I flash a kernel to my phone with the root files and in turn have cwm working? how do I know what kernels will work for my phone and firmware version specifically? I just want to do cool things to my phone now! I'm feeling i've wasted money to have it rooted since I can't do a damn thing with it right now.. SORRY for the long post, it's been 5 hours of running in circles and i'm quite frustrated. Any help at all is very much appreciated!!!
Lots of questions. First of all you can't flash anything in stock recovery not put out by Sprint or Samsung. Next you will need to use Odin to install CWM since no one click version works with GB. EH17 is a leaked ROM not official. Official version of GB is EI22. You can Odin in an EC05 ROM prerooted and then flash a EI22 prerooted ROM then if you want to change the modem flash the EC05toEI22 modem file. Here are some threads to help you:

This method you will lose all data so make sure your contacts are on Google and not the phone. Or export your contacts to the sd card.
thanks!! the links are broken but I believe I know where to go with this now, all I have to do is install a new rom/cwm via odin? which will just replace my stock "rom" I guess. I've been scared to even think about that considering that's how I bricked it the first time. Thanks for your time!
Which links are broken? If you are able to get into download mode it is never bricked.

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.
