Trying to unlock the bootloader

I get through all the steps, adb setup recognizes my device is connected. When i try to unlock the bootloader <fastboot oem unlock> command line locks up at <waiting for device>.
can someone advise?
Verizon if that matters

What happens when you type in "fastboot devices"

Nothing happens. Tried it both before and after typing in adb reboot bootloader

You sure your pc is detecting the phone when it is in fastboot mode? To me it seems like your computer isn't detecting the phone or the drivers didn't get installed properly.

answered my own question

I had the same issue. Assuming you're using Windows, you need to find where the latest Samsung drivers for the GN were copied to when you installed them (you have installed them, right?) The next time you plug in your phone, it will probably ask you to setup a new device. Tell it you will install the drivers from a location you choose, navigate to the folder where the drivers are, let it install them, restart if it asks, and then try the process over.
FWIW, I used the directions and links from this tutorial and eventually got it working. They include alternate drivers here in case the one from samsung.com doesn't work.

im having the SAME PROBLEM AND HAVE TRIED TWO DIFFERENT COMPUTERS.TRING ADB METHOD

What's the ADB method? Why don't you just just hold the volume up, volume down and power to get into fastboot mode? When you plug it in, windows should see a new device that needs drivers. You need to make sure the drivers are installed before fastboot will work.

i am in fastboot "little android with chest opened". and i do have the driver installed but in fastboot windows thinks its a different device

Is it saying that it couldn't install the drivers for Android 1.0 or something like that? What step are you at? Which tutorial are you using?
Read the driver installation part of this tutorial.

Tips:
-We know that many of you are running into a “waiting for device” issue when apply the fastboot oem unlock command. This is a driver issue and one that a reader has a suggestion for:
1. Open device manager on your PC.
2. Right click on Android 1.0 with the yellow ! mark on it.
3. Choose update driver.
4. Choose browse my computer.
5. Choose Let me pick from a list.
6. Scroll down and find the Samsung driver with newest date. Should be the driver you downloaded above. (Possibly dated 11/25/2011 ).
7. It will give you a warning about installing the driver, just click yes.

fastboot mode not working

hi everyone, i'm trying to install CM9 on my LT15i, i've tried using the CM wiki instructions and both the following guides...
androidauthority.com/xperia-arc-lt15i-root-android-4-0-ics-80265/
and
androidforums.com/rezound-all-things-root/506466-scottys-noob-friendly-root-guide-start-finish.html
the phone is already fully unlocked and has CM 7.2.0 anzu installed. i've tried simply using the clockwork recovery mod bootloader to wipe the phone and install CM 9.0.0, but on reboot the phone gets past the boot logo then just shows a black screen, so i assumed i needed to flash an appropriate ROM for CM9; this is where my problem begins.
every forum i've read about this process says i must enable usb debugging (done) and "disable fastboot" under settings>power, i do not have a "power" option in my settings and cannot find anything related to fastboot on the phone; although i'm not sure this is the problem. when android is running normally and i attempt to list devices with adb.exe on windows, it successfully returns the phone's serial number. when i shut the phone down, hold the menu button and plug in the usb cable, fastboot mode appears to work correctly as the LED comes on blue and "android adb device" appears in the windows device manager (i've tried installing the arc usb/adb drivers from various sources, they all seem to work correctly). but when i attempt to list devices after restarting in fastboot mode, adb.exe says it cannot find any device. fastboot.exe has not communicated with the device whatsoever, but i assumed i might need to get the adb.exe usb daemon/server running correctly first for this to work.
i did this process once already when i installed CM7, it was successful the first time and everything went smoothly. from what i recall i just did exactly as described above and fastboot.exe was able to find the device no problem. but that was a number of months ago, hopefully i'm just missing some obvious step.
cheers

There is no such thing. And USB debugging is only required if you want to root stock ROM, every other action can be done without it.

Drivers, drivers, drivers.
If your phone is in fastboot mode, make sure drivers are installed. Proper drivers.
You do not need ADB server for installing a kernel.
Just open up Command Prompt and install the kernel with command
Code:
fastboot flash boot boot.img
.
Assuming boot.img is in the same folder as fastboot.exe.

thanks for the reply someguyfromhell. i've tried every "android adb interface" driver under the sun for the S1 fast boot device that appears in the windows device manager when i put the phone in fastboot. when i try to send any command with fastboot.exe it just hangs at "waiting for device", i've fiddled with this stuff every which way and just cannot get fastboot.exe to see the phone. i've tried switching up the usb ports on this computer, but haven't had the opportunity to try a second computer. you've let me know i'm going in the right direction at least, if i have the same results on a second machine i'll pursue the issue further.
thanks again

You need to unlock bootloader, if you want to install CM ROM. Arc S can only have bootloader unlocked via official method, there you can also download the correct driver which you need.

[Q] Help with fastboot driver?

Greetings XDA,
I'm trying to hurry and unlock my One before Verizon locks 'er down tight, but i'm having trouble getting the Fastboot driver installed.
I've installed the java run time environment, sdk, and even the HTC my sync settings (with drivers) and am seeing "My HTC" under Android ADB devices while booted normally, but as soon as I jump to fastboot, the "My HTC" receives an exclamation point and the device driver says not installed.
I'm running Windows 8 x64 and tried these instructions here: http://forum.xda-developers.com/showthread.php?t=2232799
Any help? Any one?

I had this problem too running windows 8 x64. I think my problem was that I installed the sdk first with google's USB driver and not HTC's driver. What I did to make it work is switch computers over to my wifes which at the time I hadn't installed anything on yet. I went to htcdev.com and went to the part of the site where it is step-by-step on how to unlock the bootloader. I installed the Java Runtime Environment on the link provided on the upper right side of the site, then I installed the HTC sync manager on the link provided as well. I had my phone connected to my computer usb 2.0 (not usb 3.0) the whole time and with USB debugging enabled (not in fastboot mode, but with phone normally on). After that I took the three files from the sdk that htc wants you to place in a separate folder and put them in c:\Android. I did not install anything from sdk this go around.. i just took the three files out and put them in a separate folder as instructed by htc. After that I opened cmd and directed it to the folder I placed the files in (cd c:\Android) and ran command "adb reboot bootlader" Once I did that and hit fastboot the "My HTC" in device manager no longer had an exclamation point. So in summary, I couldn't reverse the drivers from my computer that I installed first so I resorted to using my wife's computer that didn't have anything installed yet. I installed JRE, then HTC sync software, and just used the 3 files HTC wants from sdk and placed them into a separate folder. I didn't install anything from sdk. It all worked after that. I don't have instructions on how to reverse the usb drivers you have already installed because I couldn't figure it out... in fact, I formatted windows on my pc and am reinstalling. Hope this helps.

Sadly, i don't have such a machine lying around. The wife's comp has the sdk installed as well (she's a nexus user). Although, on her windows 7 machine, in fastboot i do see MyHTC driver as ok, but when i run the "fastboot oem get_token_modifier" command, i get "(bootloader) [ERR] Command error!!! OKAY finished"
so something still quite wrong!

I don't think the Fastboot drivers work on Windows 8.
Spent all day trying, and never got recognized in ADB. Used co-worker's computer with Windows 7, worked like a charm.

.... This probably explains my problem as well. Will try on a Windows 7 computer in the morning and report back to see if that was the problem.

ADB and Fastboot both work fine on Windows 8. I had to install the newest 4.3.0.001 drivers to get ADB to recognize my One on my Windows 7 partition, despite having had the most recent behind that. My Windows 8 partition worked like a charm because I had more recently installed the updated drivers on it. It's also possible you were connecting your phone to a USB 3.0 port. ADB/Fastboot is "wonky" over USB 3.0, and if you don't have the correct USB 3.0 drivers, you have no chance at all. Also, you need USB Debugging turned on, which can be done in this version of Android by going to Settings -> About -> Software Information -> More, then tapping on the build number 7 times, unlocking developer options, then going to Settings -> Developer options, and checking USB Debugging.
And all this may be moot for now, as it appears anyone who wasn't previously unlocked won't be able to for a while.

I can confirm. I successfully got fastboot to run on OS X, but when I try to send my token via HTCDev, I'm met with error 160: MID not Allowed..

Not able to detect phone in fastboot

Tried on windows 10 and 7:
Phone is detected by ADB and commands work no problem. Boot in to fastboot (download mode) and the device isn't found when using "fastboot devices". The phone appeared in device manager with the yellow triangle but I manually updated the driver to "Android Bootloader Interface" however, I still get nothing. Am I missing something?
Thank you.

Mine never has shown in fastboot, if it shows up in device manager it should work fine. To test just try fastboot reboot.

If you corrected the issue with the driver,the problem may be with the versions of Fastboot you are using. You can download the latest Fastboot and ADB files from Google directly if you search for them it should be the first or second link.

You need google usb drivers

I have the latest google usb and platform tools on a windows 7 &10 systems using different usb ports along with multiple cables and I can not detect the phone, but I can flash.

[Q] Fixing Fastboot, and Installing USB Drivers

Hey all,
I am attempting to root my 2XL, and have so far unlocked the bootloader using ADB, however when attempting to use
fastboot boot <twrp.img>
I get stuck on < waiting for any device >
Using Deuce's flashing script, I get the following:
Checking if Fastboot exe is accessible..
Checking if Fastboot works correctly
Error! Fastboot not accessible!
Press Enter to continue...:
When attempting to update the device driver using the official Google USB Device driver inf, I get the error message
The folder you specified doesn't contain a compativle software driver for your device.
If the folder contains a driver, make sure it is designed to work with Windows for x64-based systems.
Earlier today I was able to update the device driver, and that fixed an issue I had with ADB not working, but I've hit a wall with this and there doesn't seem to be any solutions online.
Any help is greatly appreciated.
Cheers,
Boots.

How did you unlock the bootloader if fastboot isn't working?
Does the phone show up in device manager when connected and at the bootloader screen? If yes, what is the driver info?
To check if fastboot is working, run fastboot devices in the command line.
Note that USB-C ports tend to be unstable with this phone. Connect it to a USB-A port.
