[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.

[Q] Flashing custom rom from stock questions

Hi Guys,
I got the ET4G a few months ago now and I've read a lot of posts on xda about custom roms and looked on the wiki, but I'm still learning and would like to clarify some things:
1) Can I flash a EL13 rom and kernel (I'm interested in calkulin's) without changing modem? (I'm happy with EG30 so far)
2) Does the kernel version needs to be the same as the modem version (EG30, EL13...)?
3) I'm on rooted EG30 stock (auto-root), and it seems like if I want to flash rom's I would need CWM. How can I install it? Does calkulin's rom comes with CWM?
4) I'm using linux on my pc's, so odin wouldn't work, but I found heimdall, can I just flash calkulin's rom with it?

Updating to ICS roms

Hey everyone,
About 4 months ago when I got my new Epic 4g touch I rooted the phone with autoroot and installed calkulins rom which I now have at version 2.6. I am also using an ICS theme. What do I now have to do in order to get the newest modem and custom ICS roms installed on my phone? Since autoroot is no longer functional I have heard that I will have to install the stock rom and modem on my phone and then use odin to install new modems.... Is this the case? Does anyone have links to stock roms and modems I should use before I proceed into using Odin?
Thanks!

You have few options:
1. If you want latest stock rooted rom just flash sfhubs one click FF18 rooted rom from this thread:
http://forum.xda-developers.com/showthread.php?t=1721229
2. If you want any of the custom TW (stock based) roms read thru threads, see which one you like most download the rom and copy to your sd card.
Boot to recovery. Wipe/factory reset (you're on GB rom and you're not risking to brick your phone) and apply zip in recovery.
Rom will flash kernel as well and you will have rooted ICS rom on your phone.
Download CWM modem zip file from sfhub's thread and flash it in recovery as well.
3. If you want AOSP/AOKP/CM rom just read the installation instructions in OP and follow them.
If you have more questions, ask....

Thanks!!
So sprint plugged the autoroot feature but I am still able to download any ICS rom on my current setup (after full wipe) and install through my CWM and it will work? I am on the EK02 modem, I am able to upgrade to ICS modems without using Odin?

if you have custom recovery you can flash CWM modem zip from sfhubs tread in recovery.
If you don't have custom recovery use sfhubs autoroot package to flash EK02 kernel with CWM recovery and than flash rom and modem in recovery.
Sprint din't include anything for us. It's all done by a great developer sfhub.

With Sasmung devices and their ODIN support, you aren't really required to have root to flash anything. In other devices(HTC), you need to have a exploit to root them so that you have Read/write access to certain partitions that you wouldn't normally, thus allowing you to flash.

Kernels

I have a T-Mobile Galaxy S2. Rooted it withe hercules tar kernel on Android 2.3. When I upgraded to JB the kernel no longer worked (couldn't root). I tried flashing Cyangoen 10.0 and 9.0 but neither wokred (Waited 20 minutes and nothing). Is there a kernel I need to flash with ODIN?
Also, looking for a good place to learn abot kernels in genral.
Many thanks.

Kernel is causing the problem. Flash only kernel which is made for specific rom/android version. follow this if you want to flash via Odin. I recommend you to install CWM because its easy,safe and time saving.

Installed CWM Recovery, tried to flash Cyanogen 9...now it keeps rebooting back into CWM...can't access the Recovery menu. I downloaded the updated kernel. How do I get it flashed?

I was able to connect via ODIN. Can't get recovery-clockwork-touch-6.0.3.1-hercules.tar to flash.

restart your computer log back in and use a different USB port and make sure you have all the DRIVERS for the phone plug it in flash the ODIN CWM file then you should flash an ICS ROM then flash JB to avoid any hiccups 2.3.4 is a big jump to JB might be giving you errors and you are rooted correct ?

Thank you. Yes I'm rooted an runnning smoothly with Juggernaut ROM for now. Want to change to Cyanogen 9.0. I'll flash the ODIN CWM file as you recommend. Where can I find a good ICS ROM and JB? Didn't know the jump from 2.3.4 to JB would be so big.
Many thanks.

what do you prefer the more stocky looking approach or you into AOKP/CM if you like stock then anything from PTMR and JAMISON904 are on point and very stable if you want some options and custom stuff look into the CM/AOKP around here in the development forums since you are rooted i would download a nice ICS you wont be on it long so doesnt matter lol and then finally jump ship to JB give it time for the battery to settle in becuase there was nothin like GB as far as the battery life goes this one guy who has amazing work and dedication http://goo.im/devs/Cl3Kener anything on there will do you justice when you get to the JB stage good luck and happy flashing!!

C13Kener DOES have some amazing stuff. Thanks. I see that he has a nice ICS stock ROM (Samsung-Stock-4.1.2-Tiberius-Kernel-1.1.zip). Can I just flash that from recovery or do I need to flash a new kernel via ODIN beforehand? Apprecaite your patience and help.

I think there is some confusion here. A ROM is not the same thing as a kernel.

I think thats where I'm having trouble. I have an older kernel (recovery-cwm-hercules.tar) and need to upgrade it before I can flash an ICS ROM. Don't know where to find kernels for the ROMS I want to flash. I thought some ROMs came with the kernel embedded in their zipfile, but finding thats not the case. ODIN is fairly easy to use, but I don't know where to find the right kernels for ROMs like Cyanogen.

Recovery is a tool used to flash ROMs and do backups.
TWRP and CWM are recoveries.
ROMs are the operating system of the phone. They come with a kernel. The kernel is what boots the phone into the OS. You can flash a different kernel if it matches the type of ROM you are on. I hope that clears up some of the confusion.

[Q] Newb question

I keep reading and I keep getting confused. I have a Virgin Mobile S2, 4.1.2 GB28. I'm going to root using framaroot. I know that I won't be able to use stock recovery. I like the stock rom. I'm under the impression that the recovery kernels are rom specific. Do I need to flash a new rom with custom recovery or can I just flash a custom recovery kernel? I'll be using Mobile Odin.

As far as I know, none of what you are going to do needs a CWM Recovery... I could be mistaken, but I am pretty sure I am not. ROMs are recovery specific and kernel specific if it says so in the OP of whatever ROM you are looking to get. Stock ROMs are not recovery or kernel specific. You will just need to have a JB kernel/recovery be it stock or CWM. But I do not believe you will be needing a CWM Recovery unless you plan on changing ROMs or flashing mods.
