I know there are a lot threads about bricking your phone if you flash from recovery while on an ICS build. I know that you can odin back to a GB build and then flash the ICS rom as safe way to flash. My question is this. If I am running on an ICS rom and there is an update and I don't want to wipe the data, can I use mobile odin to flash a GB kernel and boot straight into recovery and then flash the ICS rom? Or will this cause issues having an ICS rom that has been flashed with a GB kernel?

The accepted method is to use the Stock EL26 CWM kernel to flash anything ICS. You can get it from here:
http://chris41g.devphone.org/index.php?dir=EpicTouch/Stock+Repack/EL26/
The reasoning is that the stock CWM recovery is deemed safer than the repacked kernels with CWM (like Rogue).
Even if you find it necessary to go back to Gingerbread, once again odin the stock EL26 CWM kernel (or the full one-click odin back to stock). Then use the EL26 recovery to wipe and flash the Gingerbread rom.
You can flash the GB kernel in mobile Odin and then boot into recovery. Just remember it will only boot into recovery and download modes. Since it still has the ICS ROM the phone won't go past the boot stage and turn all the way on. But ya you are still able to access recovery and everything so you can still flash. I actually did this the other day.

Im trying to flash calks e4gt 2 v1.1 but every zip i open gives me a signature verifcation error. I am currently on stock rooted fc05.
The re-enabled signature verification in FC05 so you can no longer use stock recovery to install ROMs.
People have been advising to flash back to a GB ROM, install GB-based CWM, then install the ROM from there. There is a big note at the top of steady's CWM thread to not use ICS-based Rogue CWM to flash ROMs, which explains why people are suggesting going back to GB-based CWM to flash ROMs. I believe technically it is only important you install GB-based CWM - ie the GB kernel, not the ROM, but folks probably suggest the ROM also because they don't like it when the GB kernel won't boot an ICS ROM.
Not saying you will definitely have issues with an ICS-based CWM flashing ROMs, but this is the method folks are suggesting to flash ROMs.
So what is the best way to go back to gb can i use stock recovery or do i need to do it on a pc. Thank you for the help btw.
The quickest way is to use Mobile ODIN or Auto Root to install a GB-based kernel+CWM like EL29+CWM-Rogue. This will put you in a situation where you phone won't boot into ICS, but you can boot into recovery.
If you are not comfortable with the not-booting situation, flash the pre-rooted EL29 ODIN OneClick, either from a PC or through Mobile ODIN:

Then use Auto Root (or Mobile ODIN) to install EL29+CWM-Rogue:

Thanks for the suggestions, everything worked.

When I install a rom with stock recovery (CM9 alpha 2 for instance), how do I get back the custom recovery in order to update the rom to the next version without having to use Odin to get back to an older rom with a custom recovery and wipe my data, then install the new version of the rom I want. Is there a better way to do this?
Use Auto Root, Mobile Odin, or Odin to install GB-based CWM.

Don't use any of the ics kernels repacked with rogue or cwm unless you hate your phone and need some bricks around the house

Go into download mode and use Odin into EL29 or EL26 you can do it for any ROMs that don't come with cwm recovery
Epic touch phone of xXHELLBoy91Xx
I keep an MD5 of a stock rooted EL29 and gunslinger kernel on my SD card and just use Odin Pro to flash it all at once from my phone. When thats done, just CWM back into recovery and flash whatever new rom you want.
Okay I found this from the blog post:
Stock android recovery is still being used in the ROM. This is for your protection, so you don't brick your phone due to all the people whom have flashed an ICS kernel, bricking when flashing a rom, wiping, etc. If you would like to backup or restore, or do any flashing, please go back to an ELXX gingerbread kernel, and do it from there.

Does this mean I can just flash future upgrades through the stock recovery if I already have alpha 2 installed?
Sorry bit isn't there a video and full write up on the first page on what to do. Just follow OP directions all will be well.

No it means cwm is bricking phones on ics kernels so it will not be included in the ROM until it's fixed ....if you want to do anything flash a GB kernel with cwm el26 ...it won't boot ics so go right into recovery

Been running Blend from Team Noc for a bit and having a lot of core crashes, as well as some issues with notifications, etc. So I installed Blend 6.0 this morning and still had problems so wanted to try something else while those issues get fixed.
I went into recovery and this is a new recov I have never seen. It simply shows the android, then the following;
Android System Recovery <3e>
I was going to wipe using Caulk's and install another ICS ROM, so went to apply update from external storage (since that was the only option that made sense). Went to the folder they were, selected the format all and it took me back to the android guy on his back with a triangle!
So I am kinda stuck with this ROM unless I can get cqm back on (I guess). There are just so many threads that are out there, some old, some new, the sg2 has 5 flavors it seems based on the carrier (I am on sprint) so from what I can tell, it's the 4G touch.
Thanks to all read/replies.
use odin, instructions here
http://forum.xda-developers.com/showthread.php?t=1609255
Just use mobile odin and select the tar file w/recovery. You tried to boot into recovery without a recovery installed which is why it looked funny.
Thanks guys. I followed the 1st post (as I didn't see the 2nd) and ran the step's using a windows machine. Odin saw the device, flashed it, all green, success, and restarted.
Followed up with the quick root/CWM app and worked like a charm. I am back to square one now, did install Venum Ice RC3.1.1 which looked pretty clean, but 1st thing I noticed was anything that uses the media card doesn't work (camera for example). You hit it, returns you to the app drawer.
So, with what's out there right now, what seems to be the most stable with the basic's, (phone, data, camera, etc.)
Thanks again, was well worth the wait to do it correctly!
I've been using CM9A3 as my everyday from. Solid as a rock. I have 0 issue.

I am also on Team Noc's The Goodness Version 6 without a custom recovery, and have a similar question. In that thread they were discussing using Odin to flash a kernel with CM, and they posted two kernals one that is the FD02 (ICS) and the other is EL29 (GB). I am currently on an ICS rom that works with the newly flashed FD02 kernal. However, my question is while on ICS can I odin to the GB recovery kernal so that I can flash a different GB rom? I am nervous to try because I have heard of people bricking going from ICS to GB, but if this works it would make my life easier as a flashaholic

Use Mobile Odin to flash EL26+cwm kernel( http://db.tt/0QJkleJR ), hold volume^+power to boot into cwm wipe data/factory reset, wipe cache, wipe dalvick, flash rom, flash gapps, and reboot. People brick from using a ICS recovery to go back from certain ROMs. EL26+cwm is always the safest choice to flash with.

Yes you can mobile odin the el26 repack with cwm (not the rogue one) I believe its still at the top of the Nocturnal Venum rom thread. Flash in cwm and as it boots hold down the volume and power buttons. It should boot into the blue cwm. Flash whatever you want. Or mobile odin the el26 repack cwm and as it reboots hold the same buttons down to boot into recovery and flash away. El29 doesnt have a cwm repack (its rogue and not what you need). Keep in mind that mobile odin WILL NOT flash modem so dont try it.
Edit: The post above says basically the same thing. DO NOT use el29 kernel. Just reminding you...

Thanks for the quick response! Just a clarification, I do have the el26+CWM (el29 was a typo). Lets say I want to leave ICS for another rom, and a use mobile odin to go back to el26 and accidentally boot into my ICS sandwich rom. Is there any potential risk of bricking there? Also, what is the significance of flashing a modem? I already have an EL29 modem and I am happy with the current setup, do most roms/kernals have baked in modems? And if so should I avoid them when using odin?

You can't boot into a ICS ROM on el26 it is a GB kernel. Every ROM I have used has baked in kernel but no modem. Any modem for e4gt will work with any ROM. Kernels are GB and ICS specific.
Edit:el26+cwm is juts safer to flash ICS ROMs/kernels. When you flash a ROM it will replace the kernel. Just use mobile odin to flash back to el26+cwm to flash new ROMs/modems(wiping like usuall). If changing modem just flash el26+cwm, wipe cache/dalvik, flash modem of choice, and flash ICS kernel of choice. Reboot.

Thanks for the tips that makes a lot of sense! I am gaining confidence of going between ICS & GB. Now is it the same process for roms like AOKP, MIUI, and CM7/9? I have heard they also need specific recoveries to operate correctly.
Yes, el26cwm only and they only use aosp kernels. I believe T.C.P. has them on one of his threads.

I have a question:
I'm presently runningthe Nocturnal Venum AOKP rom (which is awesome
I might add) but this question actually has impications on all the
ICS 4.03 & 4.04 roms. After Flashing the rom and whatever else you
flash through the EL26 CWM(5.027) based kernel and rebooting you
loose that CWM and must get CWM from the Play Store.
My question is this; Say I want to flash a new modem must I Odin
the EL26 kernel http://forum.xda-developers.com/showthread.php?t=1514665
using the method per kbizzle and then flash new modem and reflash
ICS kernel? This is important to know as the only unrecoverable brick I
have manufactured is with the flashing that goes between gingerbread
based recovery to ICS rom and attenpting to go back. I admit I'm a 50
something year old noob with building pc's as my experience before
getting into the android game so I wont pretend I'm something I'm
not! I have flased better than 100 roms and am learning more with
each possible bricking roll of the dice flashing I do and I have
bricked my share. Is their a CWM in the works for flashing modems
and so on in the works? Any help will be greatly appreciated!
to flash a modem, simply flash the .bin file in Odin. no need to use recovery and it doesn't add to the Odin count.
DO NOT USE CWM FROM THE PLAY STORE!!!!
Odin el26 cwm, clear dalvik cache, flash whatever mod you're wanting to flash, flash AOSP ICS kernel, reboot.
worked like a charm
I was having the same problem flashing modems on Nocturnal Venum. Didnt know we had to flash the kernel along with it. Needless to say working great now
It would be in your best interest to flash using ODIN. You won't have to go back to a GB kernel to flash a modem with ODIN.
You can flash with CWM, but I wouldn't in the AOKP/AOSP situation you're in.
Flashing new ICS modem
OK cnstarz,
That's what I needed to know and appreciate your prompt response! You raise another question which is was using or wanting to use CWM for nandroid backup but as it wouldn't flash modem, the nandroid backup is also out of the question. I plan on using the rom I'm on now as a daily driver but like to try others out and know that I have to basically Odin back to gingerbread to either try another gingerbread rom or to do another ICS rom. So, my guess is I have no nandroid option or is there?
Again thanks for your help.
I have some questions and need help fast if possible. I'm currently on CM10 beta 2 and only have a nandroid backup from being stock rooted. I know you can't simply restore a backup from jelly bean to ICS. I was playing with ROM Toolbox, and was installing some custom transitions. I did a backup of the stock transitions, but the zip backup file won't flash in recovery. Anyway I can't boot up and only get the Galaxy S II boot screen. I can however get into download and CM CWM based recovery. I've done quite a few searches, with no real answers for this issue. Any help will be greatly apreciated because I don't have my phone until I figure out exactly what to do. Do I have to download a stock ROM with cusom kernel to computer then transfer over file via usb using Odin and then use CWM to flash the stock ROM? I know not to do a factory wipe unless I'm on el26 or 29. I also know you can odin to them then flash, but all the odin kernels with CWM are from ICS and I can't find a solid method for my specific situation.

Thanks Blues. But I need to flash el29 or six before flashing right? So I'm guessing I need to Odin to one? And I can do that from any ICS or JB right? So I just need the one click for PC Odin, then flash with Odin? Sorry, I just want to be 100% here.

Use the one click.exe full rom file that will flash the full el29 gb rom. Then from there you can flash cwm to flash cm10 or whatever rom you want.
But do I have to go el29 or 26? How do I get there from where I'm at now? Thanks again, and sorry I just want to be 100% here.
Edit: Okay, great. After flashing that I obviously could do my nandroid restore? Just because I lost some pictures or something happened when I flashed to JB because I only had a few pics and none of my SMS or call logs or anything came through.
Ok, just so the thread is not a complete waste, I did flash the stock ROM via PC ODIN. Went back to stock, was able to do a nandroid restore, and went ahead and flashed CWM recovery via Mobile ODIN. Went ahead and wiped factory in CWM recovery and flashed CM10. Thanks again Blues, next time I'll just post in your noob thread. . I'm not a noob but I just never had to PC ODIN when not being able to boot and wasn't sure how safe it was in my specific state.
P.S. Any other users are more than welcome to P.M. me if you have any questions. I probably won't visit here again
