Mac OS X Fastboot Mode <Waiting for Device>

Hi, I am trying to Re-Lock my Galaxy Nexus GSM version, I've downloaded the SDK files (adb-mac and fastboot-mac) and all the image files and I am trying to execute the following commands:
adb reboot bootloader
fastboot flash bootloader bootloader-toro-primekk15.img
fastboot reboot-bootloader
fastboot flash radio radio-toro-i515.ek02.img
fastboot reboot-bootloader
fastboot flash radio-cdma radio-cdma-toro-i515.ek05.img
fastboot reboot-bootloader
fastboot -w update image-mysid-icl53f.zip
fastboot reboot-bootloader
fastboot oem lock
With the phone in normal mode I connect the USB cable to the computer, start Terminal windows and run the first command, "./adb-mac reboot bootloader" and the phone will boot into the "Fastboot Mode", then I try to execute "./fastboot-mac devices" to make sure the phone is connected and properly detected and I get nothing.
If I try to execute "./fastboot-mac flash bootloader bootloader-toro-primekk15.img" I get the message <waiting for device> and it will stay there forever.
Do you know what might be the problem ?, is there other method to do this ?, go back to Stock ROM and Re-Lock the device ?, thanks

You must also install the Samsung usb drivers. I have no idea how to do this in mac. A simple search will help you tho.

can't unroot/relock GNex - please help

I walked through the following steps to put the stock OS back on my device...
adb reboot bootloader
fastboot flash bootloader bootloader-toro-primekk15.img
fastboot reboot-bootloader
fastboot flash radio radio-toro-i515.ek02.img
fastboot reboot-bootloader
fastboot flash radio-cdma radio-cdma-toro-i515.ek05.img (Note: This one takes a couple minutes. Be patient)
fastboot reboot-bootloader
fastboot -w update image-mysid-icl53f.zip
I now have the stock OS loaded and can boot alright, unlocked. When I get back into the OS I turn debugging on and then head back to adb. I can browse to my device through the USB but get the following error when attaching to my device.
c:\android\android-sdk\platform-tools\adb shell
[email protected]:/ $ adb reboot bootloader
adb reboot bootloader
error: device not found
1|[email protected]:/ $
Further, if I run "fastboot devices" from my command prompt I get no devices returned.
What am I missing?? I need to get this device relocked to send back in for warranty quickly. I'm trying to get the device locked back up. Any help you can provide is appreciated!
Edit: Resolved now

nevermind... whew... figured it out.

Mark threads as solved and update first post with whats happening, so one doesnt waste time like i did.
No need to double post for that.

[Q] Unlocking bootloader failed [SOLVED]

I've installed all the correct drivers and followed all the instructions, typed in 'fastboot.exe -i 0x0fce getvar version' in cmd and it responds correctly, but when I type 'fastboot.exe -i 0x0fce oem unlock 0x8953C6AC2154D8C9' to unlock the bootloader, it always gives me the same error;
FAILED <remote: oem unlock failed!>
can someone help me?

in dialer: *#*#SERVICE#*#* > service info > configuration > Rooting status. whats written under it? whats phone model r800(?)?

Try flash tool

I used xda rom hub to unlock my booloader.

Have you double checked your unlock code? Or have you checked the root status like darkharbinger81 said. Both are common mistakes. Very easy to check too.

Bootloader unlocked: Yes.
R800i
Android version 4.0.2.a.0.42
Do I need to root it first? And the same error surfaces for my Xperia Sola... MT27i, stock 6.1.1.B.1.54, BL unlock: yes

Check (and doublecheck) what IMEI number you entered in Sony's site.
Type in dialer *#*# 7378423#*#* , go to service info> configuration and check your IMEI.
And IMPORTANT, that number will be 15 digits, but in Sony's site for bootloader unlocking you enter only 14 digits (ignore last digit)
If that fail, try some other thing:
-put usb cable in back usb ports of your motherboard
-try different usb cable
And finaly, as i recall, try by typing 0xfce instead of 0x0fce ( 'fastboot.exe -i 0xfce oem unlock 0xKEY)

Okay I went through the whole procedure again, double checked everything, the website gave me a different code and it worked this time. Thanks everybody!

How do I unlock the boodloader

I have tried running these in the fastboot:
Code:
fastboot oem unlock
fastboot flashing unlock
None of them works. The first command gives
Code:
Unable to open fastboot HAL
and the second one gives
Code:
Unrecognized command flashing unlock
.
I just want to root the phone. Overall, the phone seems great, but it is fested with nasty oem apps that I don't want to use. :crying:

Are you rooted your phone?

Did you enable 'OEM unlocking' in the developer options?
You can uninstall some apps this way

I have the oem unlock and usb debugging activaded also the last versions of adb, fastboot and the drivers but it's still not working

Hi there, I'm having the same issue. Have you been able to find a way around the problem?
