Hello I am trying to relock the bootloader on my GN with a Mac. I am at the very last step where I have already unrooted and just need to reboot into the bootloader to relock it. Problem is, my volume down button is broken so I can't get into the bootloader that way and every time I put the command ./fastboot-mac reboot-bootloader, it keeps saying <waiting for device> Please help I need to return it because my volume down button is broken!
i dont know mac but.... you can do this several ways
1) adb reboot bootloader [ensure usb debugging is enabled]
2) download terminal emulator from market and open it and type in "su" (grant it access), then "reboot bootloader"
3) your ROM.. holding down power, may have "reboot" on it select bootloader.
You can't use fastboot commands unless the phone is in fastboot.. therefore, ADB reboot bootloader or the other two methods mentioned above.

Taken FROM http://rootzwiki.com/topic/11732-galaxy-nexus-root-procedure-broken-adb-method-dont-use/
With the big change of YOU WILL BOOT LOOP WAIT FOR ADB TO RESPOND and push all the commands then pull the battery and disconnect your USB cable and reboot normal you should have perm root!
**As always RootzWiki nor myself are responsible if something goes wrong. Root your phone at your own risk with the understanding it will void your warranty and there is always a chance of something going wrong.**
*This method WILL WIPE YOUR DATA*
First download Galaxy Nexus FYA Root Package and extract it to c:\gnexroot (for the purposes of this guide)
Also if you wipe and format remember to re-enable Debug mode before restarting processes listed above.
Method
1. First, navigate to C:\gnexroot and install the Samsung drivers (Samsung_USB_Driver_for_Moblie_Phones_v1_4_6_0.exe)
1. If those drivers dont work download pdanet from here http://forum.xda-dev....php?p=19709279 and let pdanet install the drivers for you. Worked for some of us.
2. With the phone turned OFF, hold VOLUME UP + VOLUME DOWN and power the phone on. This will put you in bootloader mode.
3. Navigate again to C:\gnexroot, and hold SHIFT on your keyboard, and right click in the white space. Then, click 'Open command window here'
4. In the command prompt, type:
fastboot oem unlock
You will be prompted to confirm that you wish to unlock the bootloader. You do, of course.
5. Once the bootloader has been unlocked, it's time to boot up the device using the insecure boot.img (ro.secure=0 set in the ramdisk). This essentially means you have permanent root for the duration of this boot session. In order to boot up using that boot image, simply type:
fastboot boot boot.img
Don't expect to see anything wildly different during the boot process - it will boot as normal.
6. Once the phone has booted, in the command prompt window, type the following commands, pressing enter after each line:
adb root
adb remount
adb push su /system/bin
adb push Superuser.apk /system/app
adb shell chmod 06755 /system/bin/su
adb shell chmod 06755 /system/app/Superuser.apk
adb reboot
Again I did NOT write these steps nor did I take credit for this procedure. My goal was to have all this information easy to access here so people don't brick their new device
Edit:
If you get stuck at the google logo and cannot push adb commands, pull the battery and usb cable then reinsert and reboot. If this doesn't work Reboot into recovery and wipe everything and start over.

If you do a factory restore remember to boot at least once after and re-enable debug mode.

I would guess your computer is not recognizing the device. Try installing the drivers and connecting the phone to the computer while it is in normal mode not the bootloader. It should install the drivers correctly that way and your computer will then recognize it when you boot into the bootloader and the commands should work.
yea... you are right... it was the samsung drivers not fully loading. re-installed the drivers then doing a windows update showed that there's a new set of samsung drivers on the windows update that needed to be installed. that did the trick.
The superboot method worked just fine for me.

You must be in recovery mode. Turn the phone off, press volume up and down as well as power. Keep it there until you're in recovery and then unlock.

Its not recovery mode, but fastboot mode. If you are in recovery fastboot won't be recognized. Looks like he got it fixed by checking his drivers.
can you also use this method for a Verizon Galaxy Nexus???
http://forum.xda-developers.com/showthread.php?t=1392310
is there any difference?
Superboot method actually does the same thing as this method from what I read just one is automatic and one is manual.
Being I didn't see anyone else rooting from Verizon I took the time to figure out a manual method so i can verify each step and figure out issues if I ran in to any. With Superboot its either it works or it doesn't there is no playing with procedures.
This should work for other carriers to, I can only verify it for Verizon though.
I get past <adb reboot bootloader> just fine but then when I do a <fastboot oem unlock> it just says "waiting for device" forever. everything is installed but under my drivers it says;
"Android 1.0" drivers not installed.
plz someone help, ive searched all over the net but only found help for HTC phones and 2007 old posts.
edit: I am in "Fastboot mode"
Update the Samsung ADB driver under device manager while you are sitting in the bootloader. I'm bootlooping after pushing the boot.img
got it working, "Note: 1" under this guide fixed it.

GOod. Mine is still bootlooping back to the Google screen with a lock on it.
Booted into recovery, formatted. At least i can boot up now.

Sounds like you didn't successfully unlock your bootloader. Have you resolved this?
Done and rooted. Pushing APK's now.
I would recommend doing a full wipe first. I think something got corrupted during the forced wipe when unlocking.
After wiping, I started over. Unlocked and flashed the boot.img. Got a full normal reboot. Flashed it a second time, and it stayed at the google screen and i could connect to it with ADB. Pushed all the commands and rebooted. Works great.
Thank you.
I assume you need to have adb installed before doing this? Or do the command prompts perform from windows?

I had it previously installed. If you download the zip. its already in there, just run it right from the directory you unzip it from.
I would like to return my phone to stock. Locked, unrooted, and available for OTAs. Is there a way to do this yet?

I can see my phone and the order under Windows but i can not control my phone with the fastboot command. (example: fastboot device. the answere ist searching devices, but it comes no resolution) I loaded the last version of Fastboot, but the problem is the same.
Please can you help me. What can i do? Many thanks for your help!

And when you use adb to reboot to bootloader, what happen? Do you have "Minimal adb and fastboot tool" installed?

Sorry for my question, what´s the differents about adb and fastboot tool? I have install the last version of minimal adb and the fastboot tool, also the Windows driver for the phone. Debugging is on. I try to connect my phone about the fastboot terminal. When i try to set the phone into the bootloader mod with the fastboot terminal and the equivalent command, fastboot say´s "searching phone". My phone does not react.

So, you connect your phone, open minimal adb and fastboot too, run "adb devices", you see device id? If yes, run "adb reboot bootloader" . Phone shoult reboot to fastboot mode. Then run "fastboot devices" to see if it is connected properely.
i did it, like you described, but i see not my device id. Only the note "seach device"
Is it possible that TWRP is defect on my device? Is TWRP necessary for fastboot or only for root?

No, you should be able to use adb and fastboot with stock recovery.
After first adb command you shoult approve authorization on your phone.
Here is screenshot from minimal adb...
Phone must be in MTP mode.
And here is phone in fastboot
Many thanks for your help, now I m in my bootloader.
2 problems i had.
1. My daemon was not started correctly, i have not seen my device.
2. I used the wrong command. I started with fastboot, not with the command adb device. I tap „fastboot reboot-bootloader“,but the correct command is “adb reboot-bootlader“
Now i have seen my phone is unlocked, i hope i can root my android 6.

Just reboot to fastboot and flash surdu-petru version of TWRP recovery 3.0.2 with command "fastboot flash recovery xxxxx.img". And than reboot to recovery and flash supersu zip.
I bought a refurbished Razer phone one from the official razer eBay page, and it's stuck on download mode. I haven't tried flashing anything, I haven't even ever been to the home screen. What can I do to fix this?
Get the Google USB Driver and make sure your Razer phone is installed with these drivers
https://developer.android.com/studio/run/win-usb
Get Android SDK Platform Tools for latest ADB and fastboot tool
https://developer.android.com/studio/releases/platform-tools
Open command prompt to that folder and run these commands
fastboot flashing unlock
fastboot flashing unlock_critical
fastboot set_active a
from what i've gathered from other threads with similar problems, that's the jist of it...
It says "Waiting for any device" the problem is that it's not recognized by the computer.
Thank you ! Same problem. This is halp! after first run, works. Question, can I block it now? and how please... fastboot flashashing lock ?
Now I can block back? fastboot flashashing lock ?

Hello. Same problem. ( I bought a refurbished Razer phone one from the official razer eBay page, and it's stuck on download mode. I haven't tried flashing anything). It helped me. Now I can block back? fastboot flashashing lock ? Please, sorry my english...

"Find the driver here:

unzip the files/folder to a location you will remember
Follow the instructions below, point the windows driver update to the .inf file in that folder then driver will install. Make sure you have the latest Android platform tools, the link is also in the PDF below.

open a command prompt from within the Android sdk folder while the phone is still in download mode (phone stays and reboots to download mode through each process below making the process fairly easy)
type: fastboot devices
your phone should show up once drivers are installed correctly
type: fastboot flashing unlock
use the phone vol + - and power to select yes
phone should stay in download mode
type: fastboot flashing unlock_critical
use vol + - and power to select yes
phone should stay in download mode
Download the firmware image below or if you want to try the following command type: fastboot set_active a && fastboot reboot
to see if the phone boots, not sure if all the phones have Android installed. One poster below seems to and also seems to have his bootloader unlocked. This won't be the case for everyone. If phone does not boot continue downloading the firmware to install it
https://s3.amazonaws.com/cheryl-factory-images/cheryl-o-global-6033.zip
unzip all the files and put them in the android sdk folder, from the same command prompt if you're on Windows
type: flash_all.bat
For Mac type: flash_all.sh
Will take a few minutes but firmware will install. These instructions are for RFD members that do not either 1) want the hassle of RMA or 2) take a chance at voiding the warranty (any phone flashing via adb is frowned upon by Razer)"

"Yes. Reverse the locking procedure. Put phone back into Download mode (from power off, press and hold Vol up and then plug phone into computer) then issue fastboot commands to lock boatloader starting with critical."

Repeat the unlock commands using lock instead of unlock but in reverse order so:
fastboot flashing lock_critical
fastboot flashing lock
again you must place the phone in download mode (powered off...hold volume down key down...plug in) between each command and follow the onscreen instructions.

error: Device does not support slots
i found solution after several month, my device bricked to recovery with green blinking above the screen and it's infinity bootloop with no recovery and fastboot mode, so impossible to enter fastboot.
Q : what you should do?
A : you should prepare
1. driver and adb driver and fastboot driver,
2. you also need to open back cover and uninstall screen pin from it. and uninstall power pin and install it again.
Q: and?
1. install back cover with half installed, don't press backcover because we need install screen again.
2. plug the usb device to computer
3. in device manager you should see android bla bla this is possible to enter adb device.
4. check in adb with command :
adb devices
if device detected then go to fastboot
adb reboot bootloader
now our device is in fastboot mode, you should do this step:
fastboot -w
fastboot erase para
Q: and again?
1. uninstall power pin and install again
2. install screen pin
3. plug the back cover and press power button
4. your device now is unbricked!
bye bye infinity recovery bootloop!
i don't know this strange is happen to me when i uninstall pin it detected in adb. if you still not get in ,, try power + down button and adb device command.
i hope this tutorial work for you
