I am attempting to purchase one off eBay now and was wondering how I go about making it a real Kindle Fire HD. I have purchased two original Kindle Fire Demo Units off eBay, rooted and tried a variety of ROMs and really enjoy them. I was wondering how I go about rooted a demo unit Kindle Fire HD and what ROM I should put on it?
kindle fire
i brought my kindle fire hd off ebay as a store demo unit, the demo software is locked so you cant access the settings menu and adb debug is not enabled,
what i done to over come this is purchase a fastboot cable, when my cable came i power the kindle off plug the fastboot cable in and the device will turn on and be in fastboot mode, it will also say fastboot on the screen, install the drivers and then

i did have a issue where touch was not working on the first flash but i flashed a boot.img and it cured the problem
hope this helps

No fastboot cable needed once rooted.
You don't necessarily have to buy a fastboot cable. Its far simpler to root your kindle fire hd:
here: http://forum.xda-developers.com/showthread.php?t=2069117
To enter fastboot mode once rooted you open an ADB command prompt window and type "adb reboot bootloader".
To exit fastboot type "fastboot -i 0x1949 reboot"
Now you'd want to install Hashcode's 2nd bootloader and TWRP to flash roms.
Follow the instructions here: http://http://forum.xda-developers.com/showthread.php?t=2128848
You can download the stock kindle fire hd 7.3.1 rom and flash with twrp and the wait for a proper CM10.1 release which is due very soon.
EDIT: You can also use KFFirstAide to boot into fastboot mode: http://forum.xda-developers.com/showthread.php?t=2096888

Alternatively, since ADB is disabled and all of those techniques rely on it, you'll need fastboot....
Please, if you are going to mod your Kindle Fire.. Do yourself a favor and get a fastboot cable.

That method is only good if your not running the Demo Rom as ADB is blocked you can not access the settings menu to enable it

Straight From The Top Man who has blessed the Kindle scene. Its Strongly recommended you get a Fastboot cable and then you wont have any problems flashing if it all goes tits up on ya

Sorry 'Bout that.
I think I misread the part about it not being able to access ADB.

So I tried your method but my Kindle wont boot into fastboot. It will turn on when i plug it into my PC with the cable but just continues with the demo stuff. Should i try and get a new cable? I have the ADB drivers installed
You have to use a fastboot cord. This is a factory cord not the standard USB cord. You can make one of buy on for 10 buck or so off eBay.
First, you have to completely power down your KFHD. Hold the power button down for 20 seconds if nothing else. Now connect the KFHD 7 to the PC with the fastboot cord. You should see the word fastboot light up on your screen in just a few seconds.
Now follow the instructions provided in your quote. You can also try Kindle Fire FirstAide. The instructions provided are solid though.

For the Faint of Heart
If you're feeling really adventurous and know how to solder, you could try this. I may end up doing this as well, as I bricked my own KFHD and don't wanna drop $13 for a fastboot cable, and can't get the head off my spare micro-USB cable.
Buying demo units is nice, because you can buy the Kindle for less than half the price, put it into fastboot, and have a normal KFHD.
As for which ROM to use, I would go with @Hashcode's CM10.2. But that's just my suggestion. If you want to still have all of Amazon's media services, such as Prime Video and the Kindle Fire reading app, you can use Kinology.
So my fastboot cable will cause my Kindle to turn on when its plugged into a computer but it doesn't go into fastboot mode. Do I need special drivers on my computer for this to work? I tried it without any software on my computer and with ADB + Kidnle drivers and neither works. When I plug the cable into my Droid 4 and my computer it boots my phone into some sort of special mode, doesn't specifically say fastmode though. Do I need a new cable? Or did I buy an lemon of demo unit lol. Thanks
Edit: I'd like to add that i have the 8.9 version if it makes any difference...
Fastboot cables don't work on 8.9” models, those are much simpler to get into fastboot, at least from my standpoint, you basically just open a command prompt up and CD into he folder with fastboot and run "fastboot -i 0x1949 getvar product" and then after it says waiting for device you plug the kindle in while powered off with a normal cable. You might have to install the fastboot drivers though and that's kinda tricky because the device briefly appears as a fastboot device in the device manager when it first turns on and that's when you would have to update the drivers so it can communicate and send that command so it pops into fastboot. Probably is easier in my opinion to do it from an Ubuntu live CD after installing the fastboot command from the repos on13.10, but i only suggest that if you have driver issues.

thats it your kindle will be as good as a new product ..
hope this helps anyone looking to unlock store demo kindle units
this should work for all generations trapped in store demo mode ... aloha
Unfortunately, keaka8o8's method does not work. I tried it on a fresh batch of demo 8.9s that I received.
Kindle fire not able to find Android debug bridge yet normal debugging tools work along with fastboot using a normal USB cable.
First of all u don't use adb commands in fastboot, you still need to restore the stock ROM ( you weren't able to do this right?) so unless you have the IMG backups of boot, system and restore I can't be of much further use because I haven't used kffirst aide, otherwise I do know how to restore the backups manually, and I believe someone also posted some stock backups for people that don't have any.
I suggest trying this it has stock images I mentioned, http://forum.xda-developers.com/showthread.php?t=1951254
To clear up any confusion of step 2, it meant if ur device is accessible in adb mode and your not using a fast boot cable then u can run that command. Really think that should have been made clearer, because like I said u don't use ad commands in fastboot. That tool should restore your kindle to stock.

I have a rooted kindle fire hd 7"
I switched the Kindle Launcher from a system app to a user app in Titanium Backup Pro which caused the android to freeze.
After powering off the Kindle it will no longer boot or make connection to the PC. It is stuck on the kindle fire screen.
What do I need to do to fix this?
U will need a fastboot cable to fix it. Once you hook one up u need to flash the system image, using either kffa or the kfhd system restore utility. Unless of course u had twrp installed first, then it would be really easy to fix.

I ordered the fastboot cable table.
Once I get the cable I connect the Kindle to my pc using the cable and then what? Do I launch KFFA on my pc at that time?
Also, what is this twrp that I keep reading about?
Plug your kindle into fastboot cable, then after your kindle displays "fastboot", plug your normal cable back into your PC, make sure the drivers install or fastboot command won't work. After that either use kffa or kfhd restore tool. I don't know much about kffa because I haven't ever had to use it. If u use kfhd restore tool, ignore the command on step 2.
Oh and as to twrp, its a recovery u can install over the stock kindle fire recovery that is pretty useless. It allows us to flash custom ROMs, and u can modify a few things in the filesystem like moving that file back to where it belongs and setting its permissions. You should be fine if you Install it after you fix this, just make sure you read its instructions and fellow them to a tee or you will get a red screen on boot and have to use your fastboot cable to restore the boot loader. I recommend using seokhuns tutorial in the android development section.

Members,
I need your help for my KINDLE fire 7 " HD stuck at bootlogo. I just came back from work and switched on my KINDLE but it booted and got stuck at 'KINDLE FIRE' boot logo. I tried every possible troubleshooting method, like giving hard reset but nothing works. It switches ON and gets stuck at the LOGO. Going by the forums I know that I need a fastboot cable which I have already ordered and expecting the delivery.
Can you plz guide me how to proceed once I have the cable with me ?
Thanks in advance for your time.

You'll be fine once your fastboot cord arrives. Reference this topic http://forum.xda-developers.com/showthread.php?p=37169349 to return to 7.2.3 stock. And reference this video http://m.youtube.com/watch?v=oaNM-lt_aHw&desktop_uri=/watch?v=oaNM-lt_aHw to get your ADB drivers properly installed.

Fastboot cord uses fastboot commands while in fastboot. This is the link to Kindle Fire FirstAid http://forum.xda-developers.com/showthread.php?t=2096888 Once you follow the steps for setup and run it, you will choose number 3 to go back to 7.2.3 When asked if you want to reboot into fastboot, choose no because you are in fastboot.
You can use the regular USB to get into fastboot mode but not now that you are in a bootloop. After running KFFA to restore to 7.2.3 you will also use it to root and remove OTA updates then install gapps or if you are going to go custom romm with 2nd bootloader and TWRP recovery, skip gapps and move on to the latter. Do NOT use KFFA to install TWRP/2nd bootloader or any ROM. Use FireFlash.

So you're saying that you had a bootloop and you ran Kindle Fire FirstAide. Which numbers/options did you press? Plugging that fastboot cord in will power your Kindle Fire HD and send it into fastboot no matter the battery charge. Where did you get the fastboot cord from? A reliable source? I'm only asking because if the battery were low and the wire that connects pins 1 to 4 (think) that energize the Kindle into fastboot mode are somehow faulty, then this would stop the kindle from going into fastboot. However, if the fastboot cord is working, it would seem you have a hard brick. I will look around to see if there is a solution for this.

Thanks for help mate. I bought it from amazon and it seemed to be the most reliable source http://www.amazon.com/EarlyBirdSavi...ywords=kindle+factory+cable&tag=s601000020-20
I firstly reboot the bootloader couple of times like people suggested me. When that didn't help I restored it and like i gave a detail in other post that it took fair amount of time like 45 mins of reading and writing the .img files. Even the message was prompted that 'Your kindle has been restored to 7.2.3, the only thing is that all this while the display of my Kindle didn't changed and was fixed on 'Fastboot Kindle fire' logo. I was disappointed with this device from start due to that crappy kindle OS which made it way too slow and things kept freezing and crashing all the time. Since I am in colombia and used a freight service for this cable to be delivered, i ended up paying 30 USD for the cable. I don't think I will be sending it for repair , it just don't worth it the expenses for the repair and the shipping cost from Colombia and vice versa. May be will keep experimenting and looking on XDA if at some point of time hard brick issue could be fixed.

Thanks for the reply! Unfortunately, I can't turn ADB debugging on because there is no way to get access to the menu system. Is there another manner of fastbooting and of reflashing image you can possibly recommend to bypass not having access to the launcher? Again thanks in advance!
I'm not sure what is possible via fb other than adb. Try googling flash factory image & see what you find. Sorry I can't be of more help.

Yes,there is. The following commands will flash the boot,recovery and system images while in fastboot.

Hi im having problems with my kindle fire hd 2nd gen. I rooted and installed cm12 or 13 on it and it was working well but i lost root so i flashed Supersu through twrp now my device is bootlooping on the amazon fire boot screen. I couldn't get into fastboot so bought a fastboot cable which has arrived today (2 weeks from china) now when i plug it in the device goes into fastboot mode but my windows 10 shows it in device manager as Other Devices Tate -pvt-08. I cant issue commands through ADB (adb devices just shows nothing connected) if i enter the getvar command i just get waiting for device. I've reinstalled the kindle device driver and still no joy.
I also made a complete backup of my kindle before i rooted it which i have stored safely. but i need to know how i can push them to my kindle and how to make my laptop see the kindle.
I'm struggling now and pretty lost with it all if someone could lend a hand and tell me what im doing wrong

I have a Kindle Fire HD 7" that, prior to being bricked was running Fire OS 7.4.9. I tried to install Cyanogen mod 11 on it after successfully rooting it and somehow(still not sure how or why) bricked it. Now when it powers on, it briefly flashes the Kindle logo before maintaining a solid red screen.
I have a fastboot cable and a mac. Prior to bricking, the Fire HD was not recognized by ADB as Amazon no longer provides the ADB drivers for a mac and instead directs mac users to use Android File Transfer for transferring files.
I have searched this forum extensively and cannot find a verified(as in, something someone has actually tried) step-by-step to unbrick a Kindle Fire HD 7"(Tate) running 7.4.9, using a mac.
Any help or a push in the right direction would be much appreciated.

I can help you. It seems that you flashed the 2nd bootloader without downgrading the bootloader first,which is why it crashes the 7.3.0 bootloader,thus giving the red screen. You will need a fastboot adapter. Buy one at http://shop.teamblackhat.info
Why do I need a fastboot adapter when I already have a fastboot cable? And what would I do after getting an adapter?
