[Q] Flashing new ICS modem?

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.

Quick Question

So if i want to try an ICS rom. I just wipe a whole bunch of times then flash?
And if I want to go back I just Odin EL29 again? And wipe a bunch and then flash GB?

It really depends on the ROM you are flashing but in essence, yes that should cover you in most cases.
Once you've selected a specific ROM I'd recommend looking at the detailed instructions that are almost always in the OP.
To get back to GB I'd just use one of sfhub's one-click options.
If you have additional questions let me know, I've flashed just about every ICS ROM out there now.
Personal recommendation? Any of Team Nocturnal's ROMs kick butt!

Personally I only use el26 with official cwm to go back to gb. I just mobile odin the kernel and wipe data/factory reset, wipe cache/dalvick and flash rom. It is the safest recovery to use. El29 has rogue repack which can brick your phone when coming from ics. Ne safe and only use el26 with cwm.

OK sweet. Thanks guys. Just don't want to brick. I've already flashed a bunch of gb roms, I wanna try ics now.

Also, all ICS kernels with cwm are rogue repacks. They can flash roms,but are not recommended. Just mobile odin ro he el26 I posted above to switch between roms to be safe.
Edit: when you mobile odin el26 on an ics recovery as soon as screen goes off hold power+volume up to go to recovery as ics roms won't boot up with gb kernels.

Odin Questions

Hi all, I'm new here (well, not to XDA) as I just purchased this phone 2 days ago. I love it so far. It's such and upgrade from my LG Optimus that I almost considered not rooting or flashing ROM's. Of course, I caved in last night.
Anyway, I have a couple questions regarding Odin and the process around flashing different kernels/modems, etc. Any help would be great. I successfully flashed Blue Kuban without issues as I'm familiar with CWM and all that great stuff.
1. Is there a good tutorial that I can use to do more research on Odin? I see there's a mobile version and a PC version, so I'm not sure which to use.
2. I see in some ROM's, the install instructions state to first flash a specific kernel with Odin. Is this to prevent bricks from flashing from ICS to ICS ROM's?
3. Hypothetically, if I wanted to switch from Blue Kuban to CM9 (or any other ICS ROM), couldn't I just restore my stock GB back up and then flash CM9 (or any other ICS ROM)? If not, what is the most user friendly method you use?
Thanks all, really glad I chose this phone, it looks like there's awesome development for it! Any help is greatly appreciated!

1. OK for Odin, you can try searching for a tutorial on qbkings YouTube channel. Basically all you need to know is that the PDA slot is for kernels and such where as phone slot is for modems. Only have auto reboot checked in top right settings. Mobile Odin works the same way. You can flash kernels from there and can save you time and when you're away from a computer. It currently has problems flashing modems however. There is a paid and lite version which you can find here in xda if you search a bit.
2. Yes this is to prevent bricking which has been happening when wiping data/factory rest in custom recoveries repackaged in ICS kernels. This is why its recommended to go back to el26 because this is the last true source (we don't have ICS source yet) we had.
Whenever changing roms, you must Odin/mobile Odin the el26 cwm kernel and do any rom flashing, restoring, backing up from there. So if you want to switch to CM9 from the ICS version of Blue Kuban I'm assuming, Odin el26 cwm kernel and flash cm9+gapps there.
Anymore questions let me know

Awesome, great info and I'll definitely pick up the mobile version. So it looks like I only need to flash the kernel, not actually flast a GB Rom?
The only other thing I'm wondering is if you recommend using the Rogue CWM Recovery. I have it installed right now. Are all ROMS compatible with this recovery?
Thanks again for your quick and helpful answer!

I personally use the rouge 1.4.1 kernel to do all my flashing. Rouge recovery is built from tweaking the cwm recovery. In essence, they are the same thing. Rouge has less "no's" and the menus are better organized, so I use it.

Yea all you need is the kernel. If you're on an ICS rom when you flash the el26 cwm kernel, it won't boot your phone but you can go into recovery still.
I really wouldn't recommend any custom recovery at this time for ICS. I mean it takes maybe an extra minute odining the el26 cwm kernel or so instead of directly booting into rogue recovery. From there you can flash mods, tweaks, etc and then just reflash a compatible ICS kernel. What do you really need rogue for? Not worth the risk IMO.

Interesting. I'll have to read up more regarding Odin. So I could literally open Odin and plug my phone in and then flash the el26 kernel and flash whatever ROM I want from Odin as well? Sorry, a little confused there. Just not sure how I'd flash a ROM without a custom recovery.
Thanks again, I'll also check out some tutorials. I'm guessing it will feel like 2nd nature in a week, just learning the new process.

The recovery is built into the kernel for this device. I use odin, flash the el29 rouge kernel v1.4.1, when the phone resets after the flash, boot into recover using volume up and power, wipe, flash, whatever you want, make sure you reinstall ics rom or kernel if you are on ics and reboot.

Ah, so if I flash the EL26 Kernel, will that overwrite my Rogue Recovery?

Well download whatever rom+mods/etc and put the files on your phone. Then just odin/mobile Odin the el26 cwm kernel and flash whatever you want from there, ICS or GB without no chance of a brick.
On our phone and I think most Samsung's for that matter, the recovery isnt separate from any other partition like with HTC. It must be packed into the kernel. So whenever you flash a rom, whatever recovery is packed in with that kernel included with the rom is what you're getting. Most devs are packing in stock Android recovery to cut down on bricks and instead recommend always flashing from el26 cwm kernel.
So yea that's what makes mobile Odin so great. Have el26 on your storage and you can switch roms very fast, easy, and safe.
Anymore questions just ask.
Edit: are you on GB or ICS Blue Kuban and what rogue also?

Thanks, really good info. I'm on Blue Kuban ICS right now with Rogue CWM 5.0.2.7. Looks like Odin will be a very easy way once I get comfortable with it.
So basically, I'll put the kernel zip in the PDA slot in Odin and let it do its thing, then my phone will auto reboot into the kernel's recovery where I can flash the ROM? Or do I flash the kernel in Odin, and also flash the ROM in Odin as well?

Odin is just used to flash the safe el26 cwm kernel onto your phone. It will auto reboot and just hang at the Galaxy S II screen since the GB kernel can't boot an ICS rom so just power+volume up into it. Hold it for maybe up to 15 seconds but it'll come around. You then flash the rom in recovery from there. So put you rom files, etc on your phone before you Odin the kernel.

oh ok sweet. That sounds pretty easy, actually! LOL! One last question hopefully, do I need to extract the kernel zip or do I just place the zip in the PDA slot?
Thanks again for your help today. It really cleared a bunch of questions I had.

Kernels flashed through PDA slot in Odin will be in either .tar or tar.md5 format, .zips are for cwm recovery only. You can find the el26 cwm kernel in the kernel repository sticky in dev section, its the first kernel listed. No problem, glad to help.

[Q] Moving from Calkulin GB to Blazer ICS

I'm currently on Calkulin's GB ROM and am ready to finally make the jump to ICS, likely the Blazer ROM. That ROM hasn't been updated for a few weeks, which has obviously been a pretty eventful period of time. So I'm assuming, after I flash this from my existing CWM custom recovery, and because this ROM includes the stock kernel, that I'll need to additionally flash something like agat63's kernel and recovery to be considered "safe"? And because I'll be initially using the stock recovery with the ROM, that means I'll need to do it through ODIN or Mobile ODIN? Trying to make sure I've got all of my ducks in a row before I attempt the upgrade.
And I suppose I should ask this too, even though I know it will be speculation... I'm not in a huge hurry to make the jump to ICS, so would you guess that the Blazer ROM will eventually be upgraded to include an updated/safe kernel and recovery, thereby saving myself this small effort (which in my amateur hands still has the chance to go wrong)?
Thanks for the feedback.

Yes using the stock kernel can cause bricks. You can use mobile Odin to flash agat kernel with recovery. I did. Then from there you should be safe.
So wipe, flash ICS rom you want, then flash the agat kernel (this way you don't have to do it in mobile Odin or Odin) then from there you should be good to go

1. Odin the touchwiz kernel by chris41g which has a safe CWM recovery
2. Boot into said recovery and wipe data
3. Flash Blazer ICS
4. Enjoy

So perhaps this speaks to some basic misunderstanding of how this works, but since I'm on an EL29 GB ROM and kernel/recovery (Rogue kernel & recovery), can I not flash to Blazer ICS directly? And if I flash that new ROM, won't I end up with the stock kernel/recovery included in that ROM? And therefore still be "unsafe" at the end?
I hope that if I'm dead wrong that at least the question makes sense.
Thanks.

I just did what your asking. Make a back up. Flash the calks wipe all and then flash the rom. Read the blazer OP before you doing anything. I had no issues running like a champ
Sent from my SPH-D710 using xda app-developers app

And what was the resulting kernel/recovery *after* the flash? That seems to be the trick in my mind. Want to make sure I end up with a safe kernel/recovery after flashing the ROM.

I just went back to calks. im not sure on the kernel but the recovery was Agats tREC v0.2.0 sorry for the late response and lack of info.

Can't install ICS from Rogue EL29?

Hi all,
I just got a replacement E4GT from Sprint, I had planned on staying stock but after the hardware issues of my first iteration of this device and the somewhat lackluster update, I decided to take control and root/flash.
I used to do this on the EVO but it's been a while.
so I followed QBKing77's videos to the best of my ability. I have Rogue Recovery installed (pretty sure it's the latest, I downloaded from the official thread and ran the exe to install less than an hour ago). It's doing NAND backup and recovery just fine, so I assume Rogue is working but I can't install AOKP or MIUI.
From the video, it seems like I use the zipped file on the phone's memory, do I need to unzip first?
Can I flash directly from a EL29 Rogue to an AOSP ICS ROM?

Use Chris 41g's EL26 CWM kernel for initial AOSP flashes. Though if your stock now are you not on FF18 ICS yet?

No, No rogue for AOSP. Custom CWM bricks. Rogue was the popular one at the time, pretty sure there was another one that was not working as well.
EL26 with bone stock CWM.

RainMotorsports: I am on EL29, I've had the replacement for 3 days and it has not updated. I could follow the manual update but I hear most people like to flash from GB ROMs because they're stable?
also, I'm sorry, I don't understand flashing kernels. Don't we have to flash an ICS rom before we flash a kernel? And I thought the AOSP kernel was stock with Milestone 6?
rovar: So should I Odin back to EL26, re-root and install a recovery? Does that have a better recovery?
I'm wondering if I should just unzip the files and try again...

You can flash the EL26 cwm kernel on to the phone as is. If its rooted sfhubs auto root tool can do it for you http://forum.xda-developers.com/showthread.php?t=1342728. If its not rooted you can flash the tar for it in odin. http://chris41g.devphone.org/index.php?dir=EpicTouch/Stock+Repack/EL26/
As far as FF18 goes the leak was the OTA you can NoData one click for an OTA like experience where things are not perfect or wipe the phone with full data. http://forum.xda-developers.com/showthread.php?t=1721229
I can approach the rom/kernel question from 100 angles. But you need a kernel with the proper recovery to flash the rom, when you flash the rom the kernel is overwritten with the kernel in that rom. To get another kernel you once again have to flash a kernel. I do not keep up with AOKP. CM9 since alpha 6 has a safe cwm5 based recovery and it + the nightlies use a repacked stock kernel. Chris 41g is testing some from source kernels for both, the AOKP one requires his version of milestone 6 and thats my extent of knowledge on the state of AOKP kernels.
AOSP roms flashed with EK02 through EL29 rogue brick. Chris41gs EL26 CWM has been the tried and true kernel. You could flash the kernel of a TW or AOSP rom, the phone will not boot until a matching rom is installed but we did the reverse (EL26 kernel while the rom was still ICS) all the time.

Thank you. I found a video that showed how to get stock EL26 CWM Kernel installed via Mobile Odin. I am trying to make a second backup because I'm not sure the Rogue Nandroid is compatible but it's having trouble making a backup from here. It seems that it's only recognizing 200mb of free space and I know there's a lot more.
It seems that the EL29 Rogue backup I made won't restore to the EL26 kernel/EL29Rom I'm now running. I'm going to delete the old backup and try to make a new one.
Anyway, sounds like I'm pretty close!

And I'm now running AOKP. Thanks so much! You guys were fast and helped a ton!

Nice. I bet the addiction is already setting in. I just went from CM9 Nightly 7-22 to an early 4.1.1 AOSP build back to TCP's 7-28 CM9 which i had no clue what to expect from but I am on it now. Must must must flash them all!
Edit - I just flashed FF18 forgot I wanted to PRL update and fix my boot image while I was at it.
