I have a gsm Galaxy Nexus and I just wanted to find out what commands to use to flash a boot image from the terminal. I used to use flash_img command but that doesn't work on the GN.

you need to have a working flash_image file in your /system/bin/.

Will this work? It says ICS on it though..

Oh shoot I think I posted the wrong link. Oh well, I guess I'll see if I can Google the right path for the boot partition and try that command.

okay so i downloaded the recovery.img. and i already have s-off btw. but i dont want to mess up my phone and i dont know how to flash the recovery..someone please help me out here
Ok, so I'm guessing you have ADB installed and able to communicate with the phone.
The way I flash recovery is to use the fastboot command (part of the Android SDK, located right along side ADB). To do this, reboot your phone into hboot (power off, then hold vol down & power). Once in hboot, select the fastboot option on the phone. Then plug the phone into the computer and issue this command:
fastboot flash recovery <your recovery file here.img>
If you are not certain of what you are doing I would recommend reading up a bit - flashing recovery is something that can definitely cause problems if not done correctly.

okay so in my command prompt i have it set up to my android sdk. and i keep getting errors when i try trying in something. it says is not reconized as an internal or external command
ok well do you actually have fastboot.exe? (it should be in the sdk/tools directory).
no i do not. where do i get that?
Look in platform-tools. It should be in there. If you don't have your platform-tools set in your environment variables, you have to cd to it in command prompt.

Within the android sdk, there should be a folder called platform-tools, in addition to tools. Fastboot.exe should be in platform-tools.
In command prompt, type this:
cd C:\locationofandroidsdk\platform-tools
And THEN run this:
fastboot flash recovery C:\locationofcw3image\filenameofcw3.img
And let it run it's course. I would do a nandroid backup first, in case it screws up your /system and /data partitions like it did mine.

You can also use the android terminal emulator from within android to flash it. In terminal emulator type these commands to do it from within android:
su
flash_image recovery /sdcard/cw3name.img
You have to have the image on your sd card, and you have to have a cyanogen rom I think. Cyanogen roms are the only ones I know of that are packaged with the flash_image command. Otherwise you have to fastboot flash it from windows.

Where do you get a .img for CWM? I was able to find this link but it's a zip file with a bunch of other stuff in there.
They're floating around. There's a development thread about cm7 rc0, it had a cw3 img attachment in the op I believe. I'd link you but I'm on my phone.

I just bought a Galaxy Nexus but it was from Hong Kong and had non Yakju firmware on it. I want to install Yakju 4.0.2. I'm on a mac and oem unlocked my Nexus. I have downloaded the firmware from Google for 4.0.2 but now I need help actually installing it. If anyone could write me up a quick step by step guide I'd appreciate it, or link me to one. I'm on a Mac btw.
When I type in "fastboot flash bootloader bootloader-maguro-primekk15.img" into the command prompt it says command not found.

Wondering same thing....
Extract the archive, locate the .sh script, check the directives it contains, run them manually, or use the script.
Alternatively, do what most of us around here have to do, search. It's been covered already a number of times how to convert to Yakju as well as how to use fastboot on mac.
Edit, for the lazy, in the development section, one of the stickies have a link to this guide: http://forum.xda-developers.com/showthread.php?t=1366806
if you're on a mac, you need to add "./" before the commands in terminal
instead of "fastboot flash bootloader bootloader-maguro-primekk15.img", type in
./fastboot flash bootloader bootloader-maguro-primekk15.img
keep in mind your phone should be in fastboot mode when you do this (power off, then hold vol up + vol down + power"

I tried to follow that guide and couldn't get it to work. How do you direct the command terminal into the right folder? When they say to put fast boot in that folder do they literally mean just the executable file?

You will probably need to cd into the folder.. ie cd Downloads

Okay so I can't find a clear guide on how to root the Sprint Gnex on a Mac. I know it is simple but there is no clear guide on how to do so. I have searched on XDA and Googled it, Can someone please tell me how they rotted their's or if you know of an easy way to do so.
Thanks

Exact same as windows, except all of the commands are in Terminal instead of Command Prompt, and you put "./" before the commands.
Ex:
Code:
./adb devices
Here's the Mac ADB and Fastboot that I've used countless times attached. Unzip to your home folder and put any images or files you're gonna need for flashing in that folder. I'll assume you know how to navigate Terminal well enough to find the folder.

Hello everyone,
I have been having problems trying to install the root. When i try to run the command "fastboot oem unlock" it says "waiting for device". Is this because i installed an update that was pushed out on Friday? Or am i doing something wrong? Also Windows 7 detects my nexus tablet as a portable media player. Are there any drivers avail be for the nexus tab for windows users?
Thanks

I'm on OSX so I don't know all the fine details but it sounds to me like you are missing the correct USB drivers from Samsung for ADB to recognize your device. Not sure if you can get the drivers separately but I'm pretty sure the right ones are included with Samsung Kies.

I'm new o all this stuff, so go easy with me! :silly:
If I understand correctly the root process, this should be true (correct me if I'm wrong):
Unsecure boot.img is only used to booting as root
Booting as root user allow to use some adb command
Command adb is used to modify system.img, injecting su command and superuser/supersu apk
If this is correct, can i modify a stock JB system.img and put su/superuser/supersu apk? Will this work? Then if this is right:
How can I unpack and edit system.img?
Where I can get the original su command?
Where I should download superuser/supersu apk?
I'd like to learn this stuff and do not use any external tool, apart from fastboot and adb commands. I'm quite familiar with *nix.
Thanks for helping :highfive:
uh..am i misinterpreting something here? why not just boot a custom recovery with fastboot and flash a su/supersu.apk or superuser.apk cwm zip?

As far as I know, you cannot unpack system.img using only fastboot and adb (which you indicated you ONLY wanted to use). I know you can use this to convert it to ext4 format and then you can mount it.

Superuser is here, or, if you prefer SuperSU, it is here.
EDIT: But this is a lot of work for nothing. You could just boot an insecure kernel (which you can get from the dev section, or you could build one yourself) and then copy the su and Superuser.apk files to your device, no?
