Just flashed Calkulins and a couple questions

So i am new to Samsung (coming from a launch evo) and watched the QBKING77 videos and rooted and flashed Calkulins rom pretty easily. So far pretty simple but I have a question.
I am on stock EL29, What confuses me is the list of all the different modem .zip/.tar that are listed in the Caulkins thread. I couldn't really find a thread or video explaining what the difference is between the many different modems, or what the heck a modem is even. or if i should even worry about those at all. Should i just stick to the stock kernel that came with the rom? If i do decide to change the modem do i just flash/odin and im all set? or do i have to re flash the rom?
From what i learned so far, the kernel and phone radios are one in the same right?

Modem = radio. Also known as baseband under your settings - about phone. Modems are flashed independent of a ROM or kernel.
You can mix and match anytime you'd like. If you have solid service on EL29, no need to switch.
You can use any modem on any gingerbread or ics rom. If using a GB rom, you can't use an ics kernel and vice versa.
Hope that helps

.zip is for flashing via Clockwork Recovery. .tar/.bin is for flashing via ODIN. Most importantly it's vital to read and reread everything and also ask any questions before flashing, like you're doing now. I make Nandroid backups anytime I'm about to make ANY changes. Good luck.

Also keep in mind that anything with F in the version (ex FC07) is an unofficial leak. The latest official is EL29, which you are already on.
As a good practice when I switch modems, is to update PRL and profile then reboot.

Components come in the following packages. These packages will come either in .zip or .tar/.bin form.
1. Modem (Always separate, can use any Modem with any rom)
2. ROM (With Kernel or Without Kernel)
3. Kernel (With CWM or Without CWM, use ICS kernel for ICS rom. Use GB kernel for GB rom)
CWM = Flash .zip and make Nandroid backup
Odin = Download Mode flashing tool that can flash .tar/.bin. It can be used
Don't go around flashing your radio all the time. It can be dangerous and very brick easy.

Thank you guys! This is the info I needed. I'm sticking with EL29 for now since I'm having zero issues on the radio side. And I wasn't going to flash ANYTHING via Odin until I learned more about how it all worked.

Do I need to manually update the kernel when installing Calkulin's 2.9.2 ROM?
I installed Calkulins 2.9.2 ROM quite a while back and have been happy with it. I believe I am on the stock EL29 modem (my baseband version says S710.10 S.EL29).
I am confused about the kernel. When installing Calkulin's ROM, did I also install the "Rogue" kernel? Or did the kernel not change from the stock kernel that was on the phone from before.
From what I have read I believe that if I am still on the stock kernel then I would not be gaining the battery life benefits of the ROM because the scripts installed by Calkulin's ROM would not be running.
Currently my "kernel version" says "2.6.35.7-SPH-D710.EL29-CL852097". I believe that this is the stock kernel from Sprint. If I need to install the "Rogue" kernel, (1) where do I get it from and (2) how do I know I am using the right one for Calkulin's version 2.9.2 (and not V 3.0)?
Thanks for any assistance you can provide,
Kevin

You can find kernels in the wiki in the stickies in dev section. If you turn your phone off completely( no light on the buttons at them bottom). Then you push and hold volume up and power at the same time. Wait for it to go into recovery. Does it say e3 with blue letters or is there a green backround?

When I go into recovery on the top it says "Rogue ET Recover 1.1.2 (CWM v5.0.2.7)" and the background image says "Team Rogue". I wasn't able to find something that told me what kernel I was on.

Correct me if I'm wrong, but I believe you're on what's called a repacked stock kernel...its the stock el29 kernel with the cwm recovery added to it.

Johnny - thats the thing I dont know; I am unsure how to tell what kernel I am on. I have always been under the impression that when I installed Calkulin's 2.9.2 ROM, that it also installed the "Rogue" kernel. But I am now under the impression that I may be on a "stock" kernel.
From what I understand about the ROM, the battery saver tweaks do not work for "stock" kernel. I never quite understood what a "repacked" kernel is.

K. So there's a couple of things going on here. Let's get you some definitions.
Kernel: Essentially the backbone of the operating system. There are different stock kernels for different versions of Android (one for GB and another for ICS). A stock kernel comes with stock recovery. It is not a good idea to flash anything using this recovery (in some cases it is actually blocked so you can't).
CWM: Clock Work Mod. The original version from Chris. It is considered a "repacked" kernel. It stands apart from a regular kernel because it has a custom recovery built in. There are a few other things packed into it but the main difference is the custom recovery. The EL26 CWM is commonly referred to as stock CWM (not a stock kernel though).
Rogue: Team Rogue is the most common one you'll see for our phones. They took CWM and customized it further. They also developed custom recoveries based if the leaked ICS kernels. There was something causing bricks in the kernels they created, unfortunately we can't quite figure out why until we have source.
If you are seeing Team Rogue when opening recovery you currently have a "customized custom recovery kernel".
If you are flashing anything GB you're ok with what you have. If you're flashing ICS you'll need to use the EL26 CWM.
How this clears things up a bit.

How to re-install CWM after new ROM install

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.

[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.

[Q] ff18 cwm agat src or cwm agat

i just flashed my phone to ff18 using mobile odin. it is completely stock but i want to add cwm. i was going to use sfhub's autoroot pacakge to flash cwm. however im confused if i should choose ff18 cwm agat src or cwm agat?
any help would be appreciated...thanks

Depends what you're going to flash as a ROM...I think SRC means safe recovery meaning you can flash cm9 or an aosp rom thru it. Your best bet is just read up on his kernel and then decide.
Edit: from sfhub on his one click post
FF18+CWM-agat-src which is a recompiled kernel that is safe from EMMC along with agat's variation of CWM. chris worked with agat on this release, but it isn't the same as chris's CWM, however it is safe.
FF18+CWM-agat this is the same safe CWM as above, but repacked with the stock unsafe kernel. That means all operations handled by the recovery like wipe data/factory reset, and nandroid restore are safe. There is only slight exposure if a ROM install does a format() and include an unsafe update-binary in their installs. AFAIK no *current* ROMs do that anymore, but if you install older AOKP/CM9 ROMs you might run into that situation.
You can always just use Mobile ODIN to install whichever CWM you desire, or you can just stick the zImage from any ROM install package into the copy2sd\000root directory and choose the "generic" zImage option (there is a video on how to do that in the first post. Basically the generic zImage option will install any zImage you want to provide in the same fashion as the built-in zImage (kernel/recovery)

I suggest you find Agat's thread in the dev section with all his new kernels built from source code and flash version 2.3 that just got released yesterday. You can use Odin on your pc but that will give you the yellow triangle. Mobile Odin won't.

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.
