One thing I've noticed is there isn't a lot of documentation for getting set up and unlocking your bootloader on a Linux OS. Setting up your machine to get adb and fastboot to recognize your device takes a tiny bit of extra work on a Linux operating system, but what exactly needs to be done may not be clear to everyone. Whether it's because you're new to the Android SDK/adb, somewhat new to Linux, or can't simply can't seem to find the Vendor Code for the Nexus S. (For those who are looking specifically for this, it's '18d1', and I assume will be the same on all Nexus devices to come; If this means nothing to you right now, read on.)
Disclaimer: I take no responsibility if something goes wrong (if it does, it should be fixable though), Unlocking your bootloader voids your warranty (but you can lock it back), Unlocking the bootloader will wipe your entire phone, including USB Storage; so make a copy of all those family photos and other files you may have put onto the USB storage if you want to keep them.
For the sake of sanity, this guide assumes you are using Ubuntu. If you're using something else (or different applications), there are terminal commands offered, and you probably have an idea on how to adapt the given instructions to your Linux OS.
Preparation: Installing the Android SDK, ADB, Fastboot & Setting Up Your Nexus S to be Recognized
1. Download the Android SDK for Linux: http://dl.google.com/android/android-sdk_r08-linux_86.tgz
2. Save it in a folder of your choice. I chose to keep it in my Downloads folder, myself. If you'd like, you can rename it to the simpler name of 'AndroidSDK.tgz'. The rest of the guide will assume that you did, because I'm lazy, and it makes things simpler; it will also assume you saved it in Downloads. If you feel that you have the intuition to rename and edit the path names based on your own choices, then fine; but if you're utterly lost here, just stick with what I'm doing; download to 'Downloads', rename to 'AndroidSDK.tgz'.
3. Now that you have it, navigate to the folder you downloaded it to, right-click, and click 'Extract' to unzip it. If for some reason you cannot do this, open up a terminal and try this command:
Code:
tar zxvf /home/<your-user-name>/Downloads/AndroidSDK.tgz
You may have to adjust the command if you didn't save it under Downloads or didn't rename the file to AndroidSDK.tgz.
4. Now, we'll install adb and some other software packages by starting up the Android SDK and AVD Manager. Start it either by:
- Navigating to your AndroidSDK folder, going to the 'tools' folder and double-clicking the file called 'android'; if a popup opens asking you what you want to do with it click 'Run'.
- Using this command:
Code:
/home/<your-user-name>/Downloads/AndroidSDK/tools/android
5. In Android SDK and AVD Manager, click on "Available packages". Check the box next to "Android SDK Tools, revision 8" and "Android SDK Platform-tools", and click on "Install Selected" then "Install". When prompted click "Yes" to restart ADB.
6.You should now have a folder in /home/<your-user-name>/Downloads/AndroidSDK/ called "platform-tools".
7. Download fastboot here: http://developer.htc.com/adp.html
- Save it to the aforementioned platform-tools folder.
- Now, navigate to the file, right click it, click 'Properties', go to the 'Permissions' Tab and check 'Allow executing file as program'. Alternatively, run this command:
Code:
chmod +x /home/<your-user-name>/Downloads/AndroidSDK/platform-tools/fastboot
8. Now to set things up so adb and fastboot recognize your Nexus.
- Type this command into a terminal:
Code:
gksudo gedit /etc/udev/rules.d/51-android.rules
- Paste this into the blank file:
Code:
SUBSYSTEM=="usb", SYSFS{idVendor}=="18d1", MODE="0666"
- Click save and close.
- Then, type the following terminal command:
Code:
sudo restart udev
9. Almost done with preparations! Run this command:
Code:
gedit .bashrc
And add this line to the top of the file:
Code:
#AndroidDev PATH
export PATH=${PATH}:/home/<your-user-name>/Downloads/AndroidSDK/tools:/home/<your-user-name>/Downloads/AndroidSDK/platform-tools
Then save the file and close.
10. Download this file and save it to /home/<your-user-name>/Downloads/AndroidSDK/platform-tools: http://www.mediafire.com/?4pe5y906zr67nfh
10.We're ready to go!
Unlocking the Bootloader on your Nexus S and Rooting
Once again, unlocking your bootloader wipes everything on your device, including USB storage. Make a backup of any files you want to keep.
1. On your Nexus S, go to Menu>Settings>Applications. Select "Development" and check the box next to "USB debugging"
2. Power off the phone, and then hold down the Volume Up button and the Power button simultaneously to get into Bootloader/Fastboot mode. Connect your Nexus to the computer via USB.
3. Run this command to unlock your bootloader: (Once again WIPES EVERYTHING!)
Code:
fastboot oem unlock
Hit Enter and on your phone you will be prompted to confirm the action. (Use Volume +/- buttons to choose, power button to confirm choice) Confirm. At this point you will have an unlocked bootloader.
4. Copy/paste the following into the Terminal window:
Code:
fastboot flash recovery /home/<your-user-name>/AndroidSDK/platform-tools/recovery-clockwork-herring.img
5. Use the Volume +/- buttons to choose the Recovery option, then press the power button.
6. In Recovery, go to 'mounts and storage' and choose 'mount USB storage'.
7. Go to this page: http://forum.xda-developers.com/showthread.php?t=682828
About 1/5 of the way down on that page, find the link for "su-2.3.6.1-ef-signed.zip", which is the link for the Froyo version of Superuser. Control-click (right click) on that link and choose "Download Link As..." Save that file to your desktop and then copy it to the main directory of your mounted phone.
8. Click 'Unmount'. Go back to 'mounts and storage' and choose 'mount /system'. Then Go Back and choose 'install zip from sdcard'>'choose zip from sdcard'>su-2.3.6.1-ef-signed.zip
9. When it's finshed installing, reboot. You are now rooted.

Feel free to leave your comments on the guide below.
Good guide for beginners, I would throw in how to update their path so they can just type adb or fastboot
On Linux, edit your ~/.bash_profile or ~/.bashrc file. Look for a line that sets the PATH environment variable and add the full path to the tools/ and platform-tools directories to it. If you don't see a line setting the path, you can add one:
export PATH=${PATH}:/home/<your-user-name>/Downloads/AndroidSDK/tools:/home/<your-user-name>/Downloads/AndroidSDK/platform-tools

To confirm, yes it works on 64bit. I am running that
Thanks for the confirmation, guys
Good stuff, much appreciated.
I'm working on a simple shell script that should automate some of the more menial tasks while holding the user's hand through the process. I should have it up later today.

question:
If I use
Code:
fastboot boot recovery.img
instead of
Code:
fastboot flash recovery recovery.img
will i get OTA updates?

You shouldn't flash the recovery in the boot partition, I think that will cause problems with the phone period. :S
If you flash a custom boot.img (which this guide doesn't cover, though the script will flash Superboot) or kernel like Paul's Superboot, Supercurio's Voodoo Kernel, or Koush's insecure boot.img, OTA updates will fail to install. OTA updates will also reflash your recovery back to stock. One of the devs around here will probably start modifying them so they don't check the boot.img or reflash the recovery though.
Thanks for this! Worked perfectly
Hi all,
I have a strange problem. I can install ClockworkMod recovery but, when I reboot the phone, I don't have superuser installed and su doesn't work. If I reboot the phone, I have to install the recovery every time. It seems it isn't permanent.
Thanks

To fix the problem, before selecting zip file, you have to select mount /system. Then go to apply update.zip and proceed as usual.
Thanks

are you in the same folder that the FASTBOOT.EXE is in when you run the command???
Make sure your running CMD as administrator. You can tell by the path that shows when cmd is launched. If its a regular user account it will path to something like: c:\users\"your username"\
If your running as admin it will path to something like: c:\windows\system32

Take your fastboot files and images and put them in a folder on the root of your C: drive... I use one named phone
Then you should be able to open your Command line and type
cd c:\phone
That will change you to the Phone directory you made in the root of C: earlier
If you want to make sure you can type DIR and it should list all the files you have in there.
At this time you can start using your fastboot commands and it will recognize them.

Another handy thing is to open the folder then hold the shift key and then right click. You'll have an "Open command window here" option.
Yep I use that all the time...
used both the suggestions in here and still having trouble,can do the root of c folder,use the dir command see it is all there but the cd C:\fastbootpackage brings the same response again.Can anyone see where I am going wrong?Once the command line changes to fastboot what do I need to command?Phone is still attached (as per the guide I am following?)showing 100% phone needs manually rebooted.
I have all latest drivers on win 7 64bit and I am definetely running cmd as an administrator
Also as the third suggestion suggests if I open the cmd box from the folder what is the exact command to use from there?Is there an alternative to doing this as I am beginning to struggle?
Unlock your Bootloader
1. You need to download and install RDS lite on your PC:http://forum.xda-developers.com/attachment.php?attachmentid=634879&d=1308872277
2. Download and extract IHOP_Bell.rarhttp://api.viglink.com/api/click?format=go&drKey=1359&loc=http%3A%2F%2Fforum.xda-developers.com%2Fshowthread.php%3Ft%3D1136261&v=1&libid=1311795928774&out=http%3A%2F%2Fdiamantephoto.com%2FIHOP_Bell.rar&ref=http%3A%2F%2Fforum.xda-developers.com%2Fforumdisplay.php%3Ff%3D997&title=%5BPUDDING%5D%20International%20House%20of%20Pudding!%20(Unlock%2Froot%20thread)%20Updated%20July%2023%202011%20-%20xda-developers&txt=http%3A%2F%2Fdiamantephoto.com%2FIHOP_Bell.rar
3. Download and extract Fastboot tools http://gititbit.ch/FAST
4. Power down your Motorola Atrix
5. Take out your microSD card and SIM*card*for the flashing process
6. While turning the phone on, hold the Volume Up button until it acknowledges RSD
7. Your device will say “Starting RSD protocol support”
8. Run “RSD Lite” on your computer
9. Press the “. . .” button next to the box labeled “Filename”
10. Load up the SBF file – IHOP_Bell.sbf
11. Plug your device into your computer
12. RSD Lite should recognize your device and say “Model: NS Flash Olympus” and “Connected…”
13. Press the “Start” button
14. Be patient while the phone*reboots. It will take a long time.
15. Open and extract the Fastboot package from above
16. Open a command prompt window
a.On Windows, press Start and type “cmd” then press the enter button
17.Type the following command. Your directory will be the folder where you extracted the Fastboot package.
(Example:* cd C:\Users\Kenneth\Desktop\fastboot-package)
a.cd*your directory here
18. Power down your Atrix device
19. Hold the power button and the downward volume button until you see “Fastboot”
20. Let go of the buttons and press the upward volume button once
21. You will now see “Starting Fastboot protocol support”
22. Plug your device into a USB port in the back slot of your computer
a.Front slots sometimes do not have enough power to stay connected to the device.
23. Type the following command:
a.fastboot oem unlock
24. You will now receive a warning along with a unique device ID
25. Type the following commands using your unique device ID in place of the ####:
a.fastboot oem unlock ####
b.fastboot reboot
26. Wait for your device to reboot. Congratulations! You now have an unlocked bootloader!
This is the guide I have been using, thanks again

This msg will only show if you are in different folder than your fastboot. You don't need to run cmd as administrator. The best thing to do is:
copy those 3 files (AdbWinApi.dll, AdbWinUsbApi.dll, fastboot.exe) to your main c:\ (do not put to the folder)
Run cmd and type "cd \" this will move you to c:\
Now type fastboot and press enter - you should see various commands that can be used. (your mobile doesn't need to be connect to your pc to see this)
Now you can continue with unlocking. If you applied ihop.sbf already then startt from step 18.
I'm 99% sure that you were in the wrong folder.
Thanks very much that last post got it.In fact I would say that is the simplest way I have read so far as far as fastbooting goes.Many thanks.I have been having problems installing tenfars cwm so I will be using the rom manager "official cwm,will using the fastboot-w command be a problem for me do you think?

Don't use the Rom Manager app. It sucks and doesn't work properly. Do things properly.
With XDA forum members there's no reason to do things half assed. Use your hole ass, dammit.

Well if you came that far then try to install tenfar's recovery, download this file :recovery-en-goapk-0630-1029.zip Unzip and move recovery-en-goapk-0630-1029.img to your c:\....Now reboot your phone and enter to fastboot mode. In cmd go to c:\ and type "fastboot flash recovery recovery-en-goapk-0630-1029.img" and then "fastboot reboot" DONE
If you have any problems try to download moto-fastboot (http://forum.xda-developers.com/attachment.php?attachmentid=635584&d=1308928440). It's kind of the same thing as fastboot and to be honest I don't know what's the different between both (I think moto-fastboot is designed for 2.3.4 firmware). Extract zip and move moto-fastboot to c:\ and type the same command but instead of fastboot type moto-fastboot. I hope this make sense.
Also it's recommended to delete "install_recovery.sh" which apparently is in /system/etc/ BUT I never managed to find this file and I just ignored this step.
thanks foka, but I have already tried and tried again unsuccessfully to use tenfars cwm.I can install the recovery and delete the sh file all as normal using fastboot and astro.However for some reason there seems to be no way I can get into cwm having flashed it.when I attempt it I dont see the same menu I could scroll through as before.Then I tried a cwm of tenfars that was supposed to flash through rom manager.Again the flash went fine but could not seem to enter recovery mode.I see you installed aura 1.1 didi you flash a radio afterwards?My signal is comnstantly 1 bar.Could you reccomend a uk radio?
Well Ive flashed at&t radio N_01.77.30p which solved battery draining and 1 bar issue. I'm not sure why you can't use cwm recovery...
Sent from Motorola Atrix
What do you mean you don't see the same menu as before? When you hold volume down, power up phone, fastboot, scroll through the list and none of them say Android Recovery?
I purchased my nexus 7 from Walmart. The first thing I did was unlock and root it. But it turns out that my nexus has the screen flicker hardware issue. So how do I unroot, relock, and return to stock?
I think Google gives the factory .img's that I could flash through fast boot, but will that relock the boot loader and unroot it?
Also does the splash screen keep the 'unlocked' icon after being relocked?
That's a lot of questions, but if anyone can help that'd be great. Thanks!

EDIT: since its a hardware issue, can I just factory reset? Its not like the people at Walmart will know...
you can follow this guide.
1. Download the 4.1 (JRN84D) image files to your computer. A direct download link is found here: [Only registered users can view links. ]
While a link to the Google page you can search on if you need, is here: [Only registered users can view links. ]
2. Extract the files from that downloaded file. This will give you a folder called "nakasi-jrn84d-factory-8b0bd791"... inside of which you will find a folder called "nakasi-jrn84d"... and inside of that you will see the files we are going to fastboot to your tablet. We want to place these files into the folder we located earlier which contains our "fastboot" file. Move or copy them over to that folder.
Note: On Linux/Ubuntu you may just extract them to any easily located folder.. Create a new one on the desktop or your home folder is my recommendation.
For reference, there should be 4 files, named:
bootloader-grouper-3.34.img
flash-all.sh
flash-base.sh
image-nakasi-jrn84d.zip
3. Open a command prompt inside the folder we have set up our files in. On windows this can be done by holding shift as you right-click in the folder, then select "Open command window here". On Mac or on a Linux system you want to open a terminal/command prompt and navigate to that folder using "cd" or "change directory" commands. For example if your folder is called "fastbootfiles" and it is on your desktop, you would enter:
Code:
cd desktop
Code:
cd fastbootfiles
4. Power down your tablet. Reboot into the bootloader by holding Volume Down + Power until you see the bootloader screen. In red letters toward the top of the text you will see fastboot mode. Once here, plug it into your computer.
5. Let's make sure you have your fastboot drivers installed and recognizing your device. Enter in the command prompt:
Code:
fastboot devices
For Mac:
Code:
./fastboot-mac devices
And press enter. You should see "List of attached devices" Followed by a string of numbers. If you do not see this, you do not have your drivers installed correctly! Go back to Zero Neck's Unlocking guide and grab the correct drivers, and make sure you install them correctly. You can also find the procedure during the video posted by Ragnarokx.
If you got the expected response, let's move on to fastbooting you back to stock...
6. This first command is going to wipe all your old EVERYTHING from the device. Credit to our resident AC cowboy, Jerry Hildenbrand, for pointing out to me a minor bug with the Nexus 7 bootloader that makes this a wise step to do first. Type each of these lines followed by Enter between them, waiting for one to finish before moving on to the next:
Code:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
7. This command will flash the stock bootloader on to your device. Enter:
Code:
fastboot flash bootloader bootloader-grouper-3.34.img
And press enter. Make sure you type the command exactly as you see it.
Note: As we noted earlier, replace "fastboot" above with the exact name of the fastboot file in your folder, for your system, such as "fastboot-windows" or "fastboot-mac". Addtionally for Mac's only, the command should be entered as such
Code:
./fastboot-mac flash bootloader bootloader-grouper-3.34.img
Noting the period and forward slash before the command.
Going forward you Mac folks just remember that with the rest of the commands
Now reboot the bootloader:
Code:
fastboot reboot-bootloader
Enter.
8. This next command will both wipe your old system and flash the factory image in its place, which includes the stock system, recovery, kernel, and userdata partitions:
Code:
fastboot -w update image-nakasi-jrn84d.zip
Enter, and wait, make sure the command finishes. This might take a few minutes.
Reboot the bootloader again:
Code:
fastboot reboot-bootloader
Enter.
9. We are done with the hard part... pretty easy right? Now we're just going to lock that bootloader.
Code:
fastboot oem lock
Enter.
Yes, this step is optional but I strongly recommend it if you had issues earlier which led to this procedure. Now you can unlock again if you like, which will give your tablet that final full wipe to clear out any bad data remaining:
Code:
fastboot oem unlock
Enter.
10. Finally, reboot and setup your tablet again from scratch!
Code:
fastboot reboot

fastboot oem unlock
Enter.
10. Finally, reboot and setup your tablet again from scratch!
Code:
fastboot reboot

Thanks for the quick reply! I'll do this in the morning and report back. Does anyone have a link to the factory .imgs?

A simpler and easier solution is to use the nexus root toolkit from http://forum.xda-developers.com/showthread.php?t=1766475
Get the latest official image from google from https://developers.google.com/android/nexus/images#nakasi and use the factory restore.
Just a few things:
1. Install the toolkit to default location
2. Restart after installing
3. Click where it says "full driver installation guide" and follow the simple instructions/script to install the appropriate drivers. (necessary before you can use it; there are two possible issues with v1.5.2 mentioned but I didn't encounter any driver issues on win7 x64 nor did I encountered the issue with adb mentioned)
4. Run the flash stock + unroot script.
5. Run the relock script.

I agree the toolkit is the way to go. I stayed away from it when I rooted because the whole one click method never appealed to me on any of my android devices. That was until I soft bricked my n7 by trying to change the LCD density, then I went to the toolkit it is the real deal.

Hello all,
I haven't really seen any options for restoring our Nexus 7's using Linux and terminal commands....
SO I made one!
This guide is the simplest I could make it and it only uses a few commands to get your Nexus 7 back up and running in the event of a brick or loss of data.
AS long as you have access to the Bootloader option of the device, this tool should work.
INSTRUCTIONS
1.Make sure that you have ADB and Fastboot installed
Open Terminal (CTRL+ALT+T)
Just type what's in the quotation marks, do not include the marks
Type "sudo apt-get update"
Type "sudo apt-get install android-tools-adb android-tools-fastboot"
2. While in Terminal, browse to location of downloaded files (boot.img , system.img)
ex. Type something like "cd ~/Downloads/NexusRestore"
3. Connect your Nexus 7 to your computer with USB cable and make sure that the device is in bootloader mode
HINT: type "fastboot devices" and it should show a set of random characters and then the word "Fastboot" to the right
4. Type these commands to restore your device to a stock rooted Jellybean ROM
fastboot devices
fastboot flash system system.img
fastboot flash recovery recovery.img (ONLY use this if you DO NOT want to kep your original recovery or if you lost it due to your situation)
fastboot flash boot boot.img
fastboot -w
fastboot reboot
5. Profit
You may now go back to recovery and flash the ROM of your choice or do whatever your heart desires

Extract the ZIP file and work from that directory.
Happy Restoring!! Let me know if you have any questions or need more Help :laugh:
Not to be nit picky but the instructions you gave are for Debian based distros (most likely Ubuntu/Mint- since android-tools are a backport in Debian Wheezy), IMHO it would be better to specify that this is a Ubuntu/Mint (Debian) Guide, since other distros use different package managers.
Once you have android tools installed there is an easier method.
Download factory image, extract the tar archive, run flash-all.sh
(optionally edit flash-all and remove the -w switch to preserve user data)

I appreciate the info, I've only ever used Ubuntu Linux and every method that I had found so far was super in depth and not exactly simple. I've been doing this stuff for a while, so it's no big deal for me, but I wanted to provide something for people who don't do this kind of stuff every day. Just trying to contribute to the "cause" i guess. lol
Good tutorial

First link in "Dowload" is dead !
Thanks for this simple tuto !
In introduction of your thread, you can put this link : http://developer.android.com/tools/device.html
I have a 3rd Gen fire hdx 8.9 on 14.3.2.6. Safestrap is installed. I want to roll back and unlock my bootloader to install the nexus rom.
Is there a tutorial available? Do I need to uninstall safestrap first?
Check page 1 of this thread, basically it's all there, so read the info & the linked threads. Any questions ask first, i.e. before you brick your kindle.
Note that you can NOT use the rollback images, nor edit the build number. You must use the procedure described in post 1 of the thread and download the rollback zip I linked in post 4, you need to scroll down to get to the 3.2.5/3.2.6 procedure.

I followed the procedure but I'm not clear that I downgraded correctly. No when I look at my system update, it says I am on 14.3.0.0_user_300079820. I thought I was supposed to be on 14.3.1.0_user_310079820? The file I downloaded from the thread is indeed "update-kindle-14.3.1.0_user_310079820.bin". Is there something else I need to do to downgrade before updating the bootloader?

I checked the rollback.zip for Apollo, it seems to be in the build.prop file, so nothing to worry about.
Now you should install TWRP via adb, update the 3.2.3.2 bootloader in TWRP, and finally unlock the bootloader.
Be sure to root and disable OTA via HDXToolkit, and enable USB debugging in Fire OS, before you flash TWRP.
And be sure to create a backup of Fire OS in TWRP before you flash any custom ROM.
Thanks. Is there a link outlining the steps to install twrp via add? Sorry for the need to have my hand held through this!

You must have Minimal ADB and Fastboot installed, download the Apollo TWRP Image here, copy it to the root of the sdcard (i.e. the directory you see in Explorer when you connect the HDX to your PC, so don't open any directory there),then you open a DOS box, change dir to the adb directory (enter cd\adb), then execute the commands mentioned in the TWRP thread with the correct file name for the Apollo TWRP image.
Thanks so much. I'll give it a go tonight.

looks like I got through everything except the last remaining step of unlocking the bootloader. I confirmed that I am rooted and OTA is blocked. Not sure how to get this unlocked so I can finally have a real ROM!

OK, so you have Minimal ADB and Fastboot installed, unlocking the bootloader is really simple (with a little knowledge about command prompts), so download these drivers you need to install when the good ol' "waiting for device" issue occurs (check device manager then, the HDX probably has a yellow exclamation mark there).
You must download the software and the Python script mentioned here, and then follow the path outlined there, or (after installation of the required software) also here. Basically you just need to open a couple of command prompts (DOS boxes), change dir to the adb directory (enter cd\adb - or cd\python27 to go to the Python directory), then get the ID and serial, use the Python script with them, and finally execute the fastboot commands to unlock the bootloader.
That's it - and it's a no brainer, you can't mess up anything, if the unlock code is incorrect, it just won't flash (well, you must enter the fastboot commands correctly of course).

Thanks. Running into an error creating the unlock file. I installed python, but I don't think i installed gmpy2-2.0.7-cp27-none-win_amd64.whl (md5) properly. The error I'm getting when I run the following command "python.exe cuberHDX.py 0xmmssssssss" "is "no module named gmpy2". I am using my correct code in the previous command. When I downloaded the gmpy2-2.0.7-cp27-none-win_amd64.whl (md5), I copied into the Python27 directory. Not sure if this is correct.

Try to use the exe installer for 2.0.6 from here. If it still fails, PM me your ID and serial, I'll create the .unlock file for you then.

Thanks. It worked. I now have an unlock code. I'm not clear where my fastboot directory is? It says I need to "copy that file to your fastboot directory" before i run the commands. Would that just be the root of the kindle itself? Sorry for the question.

If you installed Minimal ADB and Fastboot, it's the adb directory (e.g. C:\adb), you should have fastboot.exe in there as well. Just copy/move the .unlock file in the adb directory, open two DOS boxes, enter cd\adb in both,
then enter adb reboot-bootloader in the first one,
and the fastboot commands
fastboot -i 0x1949 devices
fastboot -i 0x1949 flash unlock 0xmmssssssss.unlock (mm=your ID, ssssssss=your serial)
fastboot -i 0x1949 reboot
in the second (again: if you see "waiting for device" on the fastboot prompt, install these drivers in device manager for the HDX (probably sitting there with a yellow exclamation mark).

If it looked like this, i.e. unlock code is correct, then yes.
Enjoy your "free" HDX.
yes, it does look like that so I have unlocked successfully! I ran a backup using twrp, and that worked well. One problem I'm having now is that my computer doesn't seem to recognize the Kindle when connected via USB any more. I'm getting a message that says some candles are not compatible and a separate file needs to be downloaded. When I go to the Kindle support website, this is applicable for older systems running Windows XP. Have you seen this problem before? Now that I have a backup I want to move it over to my PC so I don't use all that storage.

Yes, it seems that the drivers required for fastboot cause such a problem, remove them in device manager (select to delete the driver files), then dis- and re-connect the HDX, so the original HDX drivers will be re-installed. Should do the trick in this case.
