Best way for a noob to flash radio ONLY?

I got my GSM GNex yesterday and have switched to Yakju via ODIN. (Took all morning research how to do that....shows you what my capability level is)
I'm currently on XXKK6 and which came with my 4.0.2 OTA update and I think its killing my battery much faster than KK1 was..Speeds are slower now and is constantly switching between UTMS and HSPA on TMo.
I would like to flash a new Radio ONLY....not interested in ROMs, etc.
I've been searching the most efficient / safest way to do this but I'm afraid I'm stuck without pretty clear step by step instructions.....I know there's the thread about the toolkit here - http://forum.xda-developers.com/showthread.php?t=1392310 , but do I really need to get into CWM to do this? Is fastboot the better option, and if so....can someone at least give me a few hints as to getting there?
(and maybe which radio is the one to go with)?

Go into cwm and flash the zip

Okay I've just unlocked bootloader via the toolkit...anyone care to elaborate a little further on this?

i think u need to be rooted to flash the radio

You can use fastboot to flash the radio. To revert to KK1 you can grab the radio image from the Google Galaxy Nexus factory images.
1.) Have the fastboot utilities and ADB Interface drivers installed.
2.) Download the Yakju/maguro/GSM Google factory image from here. Either ITL41D or ITL41F will work since both images contain the same radio image.
3.) Use an extraction utility (like 7zip) to extract the radio image (radio-maguro-i9250xxkk1.img) from the file and place it in your fastboot directory.
4.) Boot your phone into Fastboot mode and connect it to your computer.
5.) Issue the following fastboot command through a terminal on your PC:
Code:
fastboot flash radio radio-maguro-i9250xxkk1.img
6.) I can't remember if the phone reboots after a radio flash. If not you can use the fastboot utility by issuing a "fastboot reboot" or using the volume control and power button on the phone to select "Restart".

Okay,
I just flashed UGKL1 via CWM....I just followed the instructions from the toolkit thread.
Question about the radio zip that is now living at the root of my phone storage...can I safely delete it?
also, (this is probably a dumb one) now that I am bootloader unlocked and CWM enabled, will I still get OTA updates?

You can also flash UGKL1 radio for use on TMo network. This radio was meant for North America. Again u will have to try to search for the best one.
U can use Fastboot mode for flashing.

U can delete it if u want.. u should probably keep a folder on your computer of backups just in case u upgrade again and like the previous one more.
I think u can get updates but it will undo your root and u will have to redo it over again if u wish to flash something else

Here is a link the the guide using fastboot command:
http://forum.xda-developers.com/showthread.php?t=1366806

Extract the components of the image and flash them like so:
Fastboot flash recovery recovery.img
Fastboot flash boot boot.img
And follow that guideline for whatever else is in there (not entirely sure myself )
I don't think order matters but I could be wrong.

yup thats what i did and it worked without a glitch. when are you americans getting the gsm GN? hopefully 4.0.3/4 gsm will be out soon

Or just buy clockworkmod, download your image to the phone and flash through the app. Its very simple. Backup your device before

this is the stock 4.0.2 rooted, busybox and deodexed.

just rename flash-all.sh to flash-all.bat

Issues Updating OS Versions

Hello all, I am still fairly new to the root/Android scene and I've run into a problem.
Firstly, my Nexus' bootloader is unlocked and I'm running and older Franco.Kernel (4.0.1 and 1.4GHZ OC). Now, the problem is, my phone has notified me that a newer OS version is available. When I go to install it, the phone reboots but right after - the little Droid appears with a red caution sign and the phone stays that way until the battery is pulled.
What am I missing here? Any help is greatly appreciated.
P.S. I'm a n00b.

Try relocking bootloader then installing update. And then unlock again.

No... He's not going to be able to update just because he locked the bootloader.

In order to properly take an OTA and have it install you're going to have to be on the stock ROM, recovery, radios, everything. You can be unlocked and rooted, but you can't have changed anything else. Because you've flashed another kernel, you're probably going to have to flash the update manually.

I'd pass that question to someone more knowledgeable than I on the subject. I wouldn't wanna give you improper guidance. Not sure how your custom kernel comes in to play when flashing.
All I know is you won't be able to take the regular OTA in your current state.

Here is your info on how to get back to stock.

That is overkill. Just go here: http://code.google.com/android/nexus/images.html and download the version of Android you are using. Extract the boot.img file from within, and flash that with fastboot. Now you are back to the stock kernel, and the update will install automatically (assuming of course that you did not make other changes).
EDIT: You will not lose root, your bootloader will still be unlocked, and all of your data/settings will still be there.

Thank you so much!
I know I may seem a tad annoying, but I just don't want to mess up my phone, lol!
How do I go about installing this?
I DL Fastboot & it's drivers. Extract the IMG (just so you know, I'm currently yakjuxx, not yakju - does that matter?) to the same directory as Fastboot then enter my phone into Fastboot mode. The thing is, I'm unfamiliar with the command prompts to get it going. I'll be doing it on Windows 7. Help would be appreciated!.

I'm not sure it matters if you are yakju or yakjuux (as I think all the stock GSM kernels for ITFL41F are the same), but just to be sure, go here and download my nandroid back up of yakjuux ITL41F. In the archive, you will find a boot.img file (which is the file you need). Extract it.
All you have to do it put the boot.img file in the same directory as your fastboot.exe file, reboot your device into fastboot mode, and plug it into your PC. Open a command prompt in that directory and type fastboot devices to make sure you PC recognizes your device. Then type fastboot flash boot boot.img
Done.
Now, obviously this assumes that you already have the drivers set up properly...

The "fastboot flash" command is specifically for flashing full images to partitions on the device, e.g., system, userdata, boot, recovery, bootloader, radio, splash1, etc.

need to send device for warranty.. question about yakju/roms/unroot

I need to send my device in for warranty. It's from rogers and when I got it, it was not yakju. Right now its unlocked, rooted, and running AOKP, and franco. To put it back to oem state, I'm planning on using Wug's toolkit. That'll flash yakju, unroot it, and lock the bootloader.
My question is whether this method will flash the factory kernel too, if it'll flash the stock recovery, and if my carrier will care/notice that I have yakju installed.

Ok so I got a backup of yakjuux. But then how do I flash this via Clockwork, unroot, flash stock recovery, and lock bootloader? Can someone point me to a thread.
If I send the device in with stock yakju, and locked bootloader, would they void my warranty. Can't I just tell em it came like that. There's no way they can prove I changed it.

Sounds right
Honestly MOST company's will honor their warranties if it is a hardware failure even with unlocked boot loader and custom recovery.

I'm assuming you downloaded my nandroid backup?
Here's what you need to do:
1) Unzip the file to a folder on your PC with the same name as the zip.
2) Place that folder on your device in /sdcard/clockworkmod/download
3) Reboot into CWM and restore the backup.
4) Using a file explorer that has root access, delete the following in order: 1) the contents of /system/xbin, 2) /system/app/Superuser.apk, 3) /system/su
5) Reboot into fastboot mode and flash the stock recovery from the yakju image (it is the same as yakjuux): fastboot flash recovery recovery.img
6) Relock the bootloader: fastboot oem lock

download the galaxy nexus toolkit it can do all of that automatically for you. i had to return my first gnex and it took 20mins to bring everything back to stock. it includes everything you need except the factory image and you can download from google and put in the toolkit folder and it will flash it for you.

Here lies the point of this thread. The factory image is yakju and my phone came equipped with yakjuux.
Was yours originally yakju? if not did you have issues after you sent it back?

mine was yakju from my carrier. if you got your phone from the carrier then check if they rolled out yakju yet. if you use the images from here it will flash everything back to stock except recovery which you have to do after as well as lock the bootloader. flashing using the google images will also remove root. you can also try this cwm yajkuux from this thread

Do you read threads before you post?? The OP already said that his device came with yakjuux. It does not get "updated" to yakju... ever. So the images on Google's site are not very useful to him, now are they?
Secondly, he already said that he ALREADY downloaded my backup (from thread I started) so why are you linking to it??
Thirdly, and unrelated to the OP, the stock recovery IS included in the yakju images you linked to, so your comment about "it will flash everything back to stock except recovery" is wrong, as it does flash it.

Bootloader dumping?

Hi Everyone,
I'm about to install the new PRIMELA03 bootloader but want to retain a backup of my existing bootloader (PRIMEKK14). Unfortunately, there isn't a downloadable image of PRIMEKK14 anywhere on these forums, so I was wondering if anyone has experience with dumping an existing bootloader? ...Unfortunately, there isn't too much information on this topic either.
Thanks!

EDIT: Never mind.

Thanks for replying, but I had a look at your link and the bootloader included with that package is not PRIMEKK14. It is instead PRIMEKK15...

PRIMEKK15 is the bootloader that was bundled into the yakjuux (CDN units) 4.0.2 update, and it came shipped with my unit on 4.0.2. So if you are concerned in terms of warranty, KK15 should be good enough to revert to, as it's a bootloader your phone could have received by stock OTA update.

So I had a gander at the updater-script that updates the bootloader found in an OTA update file. It uses some sort of command to write the .img file to two partitions on the GN: xloader and sbl. If you really want to dump the KK14 bootloader, what you can do is dump those two partitions. This should allow you to replace those partitions at a later point. I would not be able to tell you how to make an image that is flashable in fastboot out of those two images.
To dump those partitions, plug your device into your computer, and open a command prompt in the same directory as your adb.exe file. Then type the following (you need root obviously):
adb shell
su
dd if=/dev/block/platform/omap/omap_hsmmc.0/by-name/xloader of=/sdcard/xloader_raw.img
dd if=/dev/block/platform/omap/omap_hsmmc.0/by-name/sbl of=/sdcard/sbl_raw.img
exit
exit
adb pull /sdcard/xloader_raw.img
adb pull /sdcard/sbl_raw.img
Now you have those two files on your computer as backup. I will try to do some more research to see how those two files roll up into a bootloader image.

If you find the thread with the yakjuux OTA update.zip to 4.0.2, that's where you can find KK15. Honestly I'd say that's good enough as a revert option because it's what you'd have had if you'd gotten the OTA to 4.0.2.

There's nothing specific about KK14 that I want (I certainly don't have a warranty with my device). I just merely want a copy for my archival purposes.

I can't remember the specific one (prob yakju IMM76D from ICL53F), but any OTA package that has a bootloader inside will show you how it flashes it.
As for dumping, given that we know that the bootloader image is written somehow split between xloader and sbl, we know those are what we have to dump. The command dd will dump partitions, so that is what I used in my instructions above.
