[Q] Kindle Fire HD P48WVB4 won't fastboot - 7" Kindle Fire HD Q&A, Help & Troubleshooting

Hi,
I have a brand new Kindle Fire HD Modell number P48WVB4 with 11.3.2.1 installed and I want to root it.
But I have the problem that the device won't boot into fastboot.
I have built a fastboot cable where i jumpered pin 1 and 4.
When I plug in the cable it starts but not in fastboot modus.
Any ideas?
Thanks in advance,
Daniel

Something with the fastboot cable wasn't soldered right probably, must guessing, not trying to put your skills down or anything. If you are interested in buying one, here's a nice inline adapter: http://shop.teamblackhat.info/Factory-Adapters-motadapt.htm

A store demo Kindle Fire HD unit, how to root it and what ROM to use?

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

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.

Because if you brick it to the point that its in boot loops or red boot loader screen that command is useless. The command is useful if your not bricked though.

Specifically owners of the Kindle Fire 2nd edition and Kindle Fire HD 7" should get fastboot cables.
The Kindle Fire HD 8.9" does NOT need a fastboot cable as that mode is automatically detected by the stock bootloader when a fastboot command is entered before turning the device on.
If you are not worried about bricking your device for a few week period while waiting for a fast boot cable that you may never need then this command is very useful, but if it has too be fixed yesterday then you should not attempt much without a fast boot cable. I built one for fun but there is no way I would have paid for one when I may never need it.

If you have a KFHD 7" I think you should invest in a fastboot cable anyway. I picked one up off eBay for $4.45 including shipping and it came in a few days. I didn't think I would need it until I ended up bricking my device when I tried to apply a wallpaper fix. Only used it a few times, but it helped me load CM10.1 with confidence.

I am stuck in the loading screen (kindlefire text) but not fastboot. I have tried both normal cables and a service cable. I have a Kindle Fire HD 8.9"
Now I just can't connect it with anything? Is it Texas Toast?? Can't get it out of the load screen and can't turn on fastboot. No adb services.
Hello, I have a 2nd Generation Kindle Fire with red screen when I connect in fastboot lights but the pc does not recognize. please help.

Holy crap! Thank the Gods! I was stuck in a strange bootloop that kept refreshing the Teamwin logo, and that's all it'd do. I was able to successfully install drivers and enable adb. I tried almost every solution (without a factory cable or fastboot capabilities) to reflash the recovery image. Thanks to this, I think I just got my kindle out of a bricked state. Will check back if successful.
Hi i have bricked my kindle fire hd 7 generation 2 tablet. It is not turning on....no changes on screen. Its heating up when connected to charger but not connecting to pc or showing any sign of life. I tried a fastboot cable also
Ugh, I'm the worst. Just bricked the Kindle Fire HD 7" (2013) 3rd Generation trying to Debloat apps which constantly were popping up in the background and crashing Star Wars Heroes two-three times per hour. I was side-loading those apps using "Amazon Fire Tablet Tool" from here at Rootjunky.com
Copied the files over using my regular plain old (NOT fastboot) USB cable and things sort of worked for the past month, downloading various APKs and installing from my Windows 10 Pro desktop pc. But now i'm dead in the water. Tried pressing and holding power & volume for 30-45 seconds to force a reset, but didn't seem to cure the issue. Still stuck at "kindle fire" load screen.
Thanks in advance for any assistance.

[Q] Kindle Fire HD 8.9 bricked help

Ok i have a Kindle Fire HD 8.9 bricked.. turns on to the kindle fire screen and stays there....
what i have done so far::
1. tried the factory cable with KFHD_SRTv1.3.5 and KFHD_SRT_v2.1
my computer recon. the kindle fire and i can do enable fast boot from KFHD i see the kindle screen goes black then the kindle fire screen comes back up and stays...
2. KFHD_SRTv1.3.5 - option 3,4,5 all work but 1,2 say the failed remote data to large
3. KFHD_SRT_v2.1 - option 1,4 works..2,3 say the failed remote data to large
4. Kindle_Fire_Utility_v0.9.6 won't even work says ADB Status: Offline
am i doing something wrong ??? i am using windows 7
Don't use kindle fire utility on a kfhd u can hard brick it..
I am a bit unsure as to exactly what is going on, did you get it into fastboot mode because it doesn't sound like you did. Keep in mind factory cable isn't the cable your kindle came with, I call them fastboot cables so as not to confuse people with that term. If it is in fastboot mode your kindle should say fastboot in big letters on the screen. If it does get into fastboot and your having this error then I suggest checking to make sure your fastboot drivers are installed since kfu said its offline. Seriously though don't use kfu it can hard brick your device. On another note I just remembered you said this is a kf8.9. If you have adb laying around I suggest running the command on the system restore utility instructions. Then plug your kindle in and power it on, it should go into fastboot from what I have heard about 8.9 inch kindles.

[Q] Stuck on Kindle Fire Bootloop

This is my 1st time asking for help since I really have never needed it. I got a kindle fire HD 7" and rooted it. I added TWRP and a 2nd bootloader. For a long time I was stuck in TWRP and every time I tried to reboot it would just go back to TWRP. This morning I tried using the Kindle fire utility and selected option one. It seemed like it worked. I then rebooted and now I am stuck on the Kindle Fire boot screen. It shows Kindle fire on the screen, goes black for a few seconds, then back to the kindle fire, then goes black again. It keeps doing this over and over again. I am not able to get back into TWRP now. I am not sure what to do at this point. I have read just about every thread out there and cannot find a similar situation to mine. Any guidence would be appreciated.
OK mistake number one, do not use kindle fire utility on a kfhd, you could easily hard brick the kindle. That was designed for first gen it's and they work a bit differently than yours. OK now that I got that out of the way, does your kindle still have the logo turn blue?
Sent from my Amazon Kindle Fire HD running CM10.1 Tablet UI using xda-developers app
Thanks for the quick reponse. When I installed the 2nd bootloader and TWRP I got into the bootloop. At that time when it would bootloop it would go from orange to blue twice before going back to TWRP again. After I made the mistake of using the Kindle FIre utility it now just keeps on the kindle fire start-up screen and it is always orange.
You are either going to need a fastboot cable to fix or have some luck getting a command to work... If you open the device manager, and plug your kindle in while its off, does a Tate device show up for a few seconds? If so try updating the drivers on the Tate device to the ones in my signature. From there you should be able to use a fastboot command to get the kindle to boot into fastboot. The command would be "fastboot -i 0x1949 getvar product", but if your not seeing a Tate device then this command will be useless, and I don't wanna finish explaining how to use this command until I know your PC is detecting it, assuming you don't know how to use the fastboot command by itself from a command prompt since I don't know your skill level with android stuff and windows command prompt stuff.

Thanks again for replying. I would say my experience level is low when it comes to command prompts. I get the basics though. I will check when I get home if I see if a Tate device shows up when I connect with my usb and get back to you. Even when I was in TWRP I was having difficulty seeing my device on the computer to add a custom rom to the sd card. I tried sideloading and tried mounting the sd card but nothing worked. I wish now I would have just left it in TWRP and did some more research. Live and learn I guess. I will let you know what I find out. Thanks again.
Ok. I turned off the Kindle and then attached the USB to the computer. Nothing is being recognized. I see now too that my adb interface is also gone. It appears the computer is no longer picking up anything. When I attach the Kindle to the computer it starts the bootloop again flashing the kindle fire screen over and over again. Let me know your thoughts. Thanks again.
I think your only hope is a fast boot cable, and honestly or just depends how broke it is whether it works or not

Ok. I wanted to clarify what I did to get in the situation that I am in. I rooted my device with no issues. I then decided to install a 2nd bootloader and TWRP. After all was done my Kindle Fire HD 7" booted to TWRP. I could not get my computer to show my device so I was stuck. Every time I would reboot it would flash kindle fire in orange, then in Blue, then in Orange, the in Blue then would go back to TWRP. I then put the device with the USB attached to my computer and from TWRP I put the device into fastboot mode. I then used the KFHD SRT v1.3.5 tool and opened the SR.Tool.bat and chose option 1. After it was done I rebooted and now I am stuck on the Kindle fire screen (in orange) and it will show for a few seconds, turn off, then go back to the kindle fire screen again (in orange) and just keep repeating. I ordered a factory cable to try to get back to fastboot mode but since it did not work for me the 1st time I was wondering if anyone had any ideas for me. Thanks in advance.
Are you sure it is a factory/fastboot cable? I would either get them from skorn or proxenusa since I know they are reliable.
Sent from my Amazon Kindle Fire HD running CM10.1 Tablet UI using xda-developers app
Hello again. I don't have the factory cable yet; I just ordered it yesterday. When I used the fastboot mode the last time I entered the mode from TWRP and was connected to my computer with a regular usb charger. When it was in fastboot mode I selected the option 1 from the tool I mentioned in my previous post. I am just wondering if the fastboot did not work with the KFHD tool I used because I did not have a factory cable connected hence why I am stuck on the Kindle fire screen. What do you think?
No, typically it is said to use a fastboot cable just to get the device into fastboot, then plug the normal cable in afterward.
Sent from my Amazon Kindle Fire HD running CM10.1 Tablet UI using xda-developers app
For future reference, when you get your kindle back up and running again, you need to flash a custom ROM to boot. The TWRP boot loop stems from trying to boot into stock ROM, it won't work. So just put a ROM on your kindle before you flash bootloader + twrp next time.
