I would like to test out the MESA kernel, but before I do that I want to backup my stock kernel so that I have something to go back to. How can I back up my stock kernel?
Is there a way to extract the kernel (as a .img file that I could flash if I ever want to go back to my stock kernel) from the FTF that I have already flashed?
Thanks,
Tim
Idk about backing up kernel, but what you can do if you want to return to stock kernel, in flashtool when you select what you wanna flash, just exclude everything but kernel, that should do it

When I have had trouble with a custom ROM, or changing file format, I usually odined back to 2.1 JDF with JAC's odin file and start again with a clean stock base. Doing this is kind of a PITA, having to root again and flash CWR before I could flash a custom rom.
Is there any benefit of using odin to revert to JDF anymore or can I get the same results if I use CWR to flash a rooted, de-odexed, stock 2.2 rom IE re-setting the phone and getting a clean "stock" base from which to flash a custom rom?

Not sure if you've done this, but when you've first flashed CWR did you do a back up? From what I understand, with that back up you can just flash back to how your phone was prior to flashing the custom rom. I've never tried it though, I've always odin back to stock just in case.
Yea I normally make a nadroid backup via CWR and Ti backup of apps, then copy the SD card to my desktop. A nadroid backup will not re-flash the modem or kernel. The only way to do this was odin but now CWR can. This is part of my reason for asking the question in the OP. If CWR can flash rom, kernel and modem, is there any benefit to using ODIN to get back to a clean stock rom?
Flashing back to stock is always the cleanest way to go. You do not risk
"ghost" remnants from old flashings. Nice clean slate... is always the best way to go. Reverting back to stock from CWR backup I have not do that it would defeat the purpose of wiping old data from the firmware. So, I always do a reflash back to stock when putting Real new software. I do not if I am just upgrading from older version of custom rom xx to a newer version.
Oka1,
thanks. Do you use JAC's JFD, link, or is there a mildly tweaked Odin file that will give a rooted stock?

If you go to the vibrant directory bible there are stock rims that have been rooted.

Thanks. Although the bible has CWR rooted roms, I do not see any that are ODIN. Which was sort of the reason for this thread, CWR vs ODIN to get a clean, ghost free, platform to flash a custom rom.
Hi. I'm on FXP30b, and I need to go back to stock ROM for some test with headset, what's the easiest way to do it? I have backup of stock but from xrecovery(I guess I can't restore it using CWM Recovery). I think the fastest way is to flash Baseband .71 with stock kernel and stock ROM? What about going back to FXP30b from stock, can I just flash FXP kernel and with CWM recovery restore my current backup? Will that work?

the easiest way would be to do a factory reset using your SEUS or PC companion, just click on repair then you can always root it again so you could get back to your current version, just make a back up of what you have now
Use flashtool

So let me see if i understand this correctly. From what i have read, it looks like i cant install CWM recovery without installing a custom Kernel? So me backing up my stock set up is pretty much out of the question? So everytime i wish to install a different custom rom i am essentailly reinstalling CWM recovery as well?
How can i backup my stock set up and restore it if i screw something up, or install a rom that i am not happy with? I am coming rom an epic 4g on sprint and it was different with that galaxy phone.
Flash a CF Root kernel that matches your firmware, create your near stock b/u. This will be your point to fall back on. 99.99% of ROMs you flash will include a kernel, that also has CWM, it may be a different version but they all work the same, for the most part. The majority of kernels include CWMr 5 or higher.
You'll always have the option of restoring your "stock" b/u so long as you don't delete it. Titanium b/u is the ticket to back up all your apps and their data rather than having to extract those apps/data from a CWM b/u.
You only have to root once. The easiest way to unroot is to flash a stock firmware. Flashing a stock kernel back on after you've rooted will replace CWM recovery with stock recovery, but you'll remain rooted. Probably doesn't address all your questions, but you've got a start.

forgot to mention that i am rooted now. using oneclickroot.
Just flash a custom kernel with CWM recovery installed inside.
Such as:
- Siyah
- Phoenix
- Ninphetamine
etc...
DO NOT FLASH STOCK KERNEL AS IT WILL DELETE CWM RECOVERY. ROM MANAGER DOES NOT INSTALL RECOVERY ON YOUR PHONE.

is it as simple as using Odin, clicking PDA and flashing the downloaded kernel? and there should be no side effects from using a custom kernel such as Siyah?
Getting back to 100% stock is easy, odin flash a rom.
CF root *is* the stock kernel, just with some bits added (CWM recovery and root).
CF root with your stock rom is defo the safest bet.

Yes if you get the kernel in odin tar file, otherwise flash CF root and use CWM recovery to flash the zips.
Hey, guys, how can i get back to LWW stock kernel?
Does anyone has a link of LWW stock kernel?
Flash the ftf file of your phone with flashtool.
It will automaticly flash back to stock kernel
Make a backup of your stuffs before flashing
Sent from my WT19i
You can just flash the stock kernel without wiping out any data from your phone .
select the ftf in flashtool and select the option to just flash the kernel.
The option to flash the kernel will be provided to you prior flashing the ftf in the right side of the flashtool window while selecting the ftf file.
Make sure you just flash the kernel if that's what you want .
HIT THANKS IF I HAVE HELPED YOU !

odin to the stock and rooted, wheres the best kernel so i can flash a rom? and im on rooted stock do i flash the rom first or kernel first or does it matter?
btw i tried triangle away but it does not work something about magic header should i flash the rom and kernel then try it or is there another way?
and can i flash twrp on this for my recovery?
Use mobile odin lite or mobile odin pro to flash the AJK v4.9 No Swap kernel to get CWM recovery. Open the zip archive and extract the boot.img, and flash that in mobile odin. Do not need to boot into system, and if you do, the buttons will not work correctly. Boot into recovery and flash the firmware of choice.
If you want something touchwiz based, then the best choices are either SHOstock3 v4.0 or Cooked. If you want something AOSP based, then there are a few choices which you will need to research yourself. You can probably have TWRP recovery by flashing a custom kernel containing TWRP, but this will depend on which firmware you choose.
