Help unlocking bootloader - Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot

Hi all.
Just brought my Mrs a Amazon fire hdx 7, from eBay never been used or opened box.
The rom info is saying i have 13.3.0.5
I would like some help on unlock the bootloader so I can custom rom it for her, but also wondering if there was a way of running Amazon fire OS just in case she would prefer that is.
I'm not sure how I can unlock the bootloader, read info but getting confused on where to even start.
Any help please.
Much appreciated, thank you.

Ok, if you don't know what you're doing, ask first, i.e. before you brick you HDX!
If you haven't done it yet get HDX Toolkit to root and disable OTA updates.
Afterwards you should install TWRP, and update the bootloader to 3.2.3.2 via TWRP.
Then try the one click solution to unlock the bootloader. Could require these drivers, you probably will need if the one-click solution doesn't work for you, and we've to do it the hard way (i.e. manually).
Before you flash any custom ROM be sure to create a backup of your current Fire OS, and move it to your PC!

Thanks for the advise I'll have a butchers at it after I finish work. Fingers cross I can do it.
Thanks again.

@Cl4ncy

You're welcome. Enjoy the 'free' HDX.

Where does it fail at? Are the fastboot drivers loading correctly? 2012 or 13 model? Wifi or Wifi + LTE? What update is on it currently? Is the bootloader unlocked?
Once you get the drivers loaded and the correct firmware for your particular model, it's not difficult to restore manually with fastboot commands. I'm hesitant to link to a specific guide without knowing which tab you have, but there are tons of guides both written and on YouTube for whichever version you have, I'm sure.
If you're in a hurry, the best way to get a hold of me is on Hangouts. Name is in sig.

Thank you for replying!
In the about section it said Nexus 7 (no v2)
So my official answer is ASUS Nexus 7 Wifi and that's what I picked in the Rootkit based off of the instructions to go off of the "About Device"
I went through the instructions on the Rootkit and installed the "Raw" drivers and was successful in the sense that my PC detected it and it passed the driver test.
It came with 4.4.2
It is currently Unlocked but is stuck with the Google logo and an unlocked lock at the bottom of the screen.
Let me know if you need any more info
THANKS!!!

[Q] I think I've got it? (from root to rom)

From many many different threads and frankly confusing instructions I think I have puzzled together the following solid guideline for my kindle fire hdx from basic root to custom rom. Currently my firmware is 13.3.1.0.
Could someone take a look at this and tell me if I got this right or if I need to do stuff differently (or could do them better)? Don't assume that something is obvious, if it isn't written down, don't be shy to mention it. I would be ever so grateful .
Edit: I'm updating my experience as I move along the list and get more info just in case this might be useful to someone who is just as lost as I was in the beginning
Obligatory disclaimer: this is just a step-by-step guideline that worked for me. I'm not responsible if you chose to follow any of these steps and damage or brick your device.
Guideline:
-Download firmware version 3.2.3.2 and upgrade directly from any of the previous version by putting the file into the internal storage of the kindle, going to settings>device>system update on the kindle and installing the update from there.
-Root with Towelroot in the HDX toolkit downloaded from here (Edit: I got various error messages at this step but got it to work in the end. The 3rd post here shows what I did to get it working after getting error message 2 and 3 at various times)
-block OTA also with the tool in the HDX toolkit (is there a way to safely check that this worked? Edit: It worked )
-connect to wifi and install Flashify from the playstore (Edit: I ended up installing File Expert and flashify on another android device, backing up the flashify apk and sideloading it with ES File Explorer from the amazon app store to the kindle, I guess I could have also download the apk somewhere but I have trust issues.)
-download the img of TWRP 2.8.5.0. and put it in internal storage of kindle (had no problems)
-use flashify to save original stock recovery (had no problems)
-Use flashify to flash TWRP (had no problems)
- Boot into recovery mode via flashify to see if it worked (had no problems)
Now either A)
-download CM11 image and gapps and put the zip files on internal storage
-Edit: disconnect Kindle from USB afterwards
- go into TWRP recovery mode (by powering off kindle and then pressing power and volume at the same time)
- make backup of original stockrom under backups and save copy on your Computer
- wipe system, data, cache and dalvik cache under wipe/advanced (all except internal)
- flash cm11 image and gapps (under install and then find them in the files)
- reboot
-Edit: I had the wifi not connecting problem that some people have with CM11 but a reboot took care of it.
-Edit 2: I couldn't get the kindle app to work on CM11 (it wouldn't synch my books, the device wasn't recognized by amazon and it would crash every time I logged in.) so I ended up replacing it with the Nexus rom. If the chance of this happening doesn't bother you then CM11 seems to still be a good choice.
or B)
- download HDX thor nexus rom and gapps and put the zip files on internal storage
- go into TWRP recovery mode (by powering off kindle and then pressing power and volume at the same time)
- make backup of original stockrom under backups and save copy on your Computer
- wipe system, data, cache and dalvik cache under wipe/advanced (all except internal)
- Edit: disconnect Kindle from USB afterwards
- flash nexus rom and gapps (under install and then find them in the files)
- reboot
- Edit: I'm very happy with it, it works flawlessly. Since it's based on Jelly Bean I may try replacing it with another rom sometime in the future, but I'm in no hurry
Mostly correct, you can update directly to 3.2.3.2 no need for incremental steps. The only way to know if ota blocker worked is to check for update but there's really no need, as soon as you've run towel root just disable WiFi as it won't be needed anymore.

You can flash a cuber signed TWRP on a locked bootloader, as long as you're below 3.2.4.

Fully unlocking your bootloader is definitely worthwhile but it's quite a complicated endeavour and not required for running the current custom recoveries and ROMs. I'd recommend you stick with your current method and read up on the unlocking process once you're more conformable working with this device.

- more robust recovery options when recovery (TWRP) is damaged/inaccessible; better chance of reviving a bricked device
- some custom roms install/operate better with unlocked BL (technically should not be needed but sometimes seen in early builds)
- some DRM aware apps on custom roms work better with unlocked BL(eg: playstore, prime)
Guidance form derpadoodle is sound. Enjoy what you have achieved thus far; revisit BL unlock when you are more comfortable with device/technique.

Thanks for the sound advice, I will probably never feel comfortable enough for that , especially because I haven't achieved much at all yet. I haven't even flashed TWPR yet.
Yay, I did it. CM11 seems to be working as intended! Thanks again for everyone who replied and also to everyone who put so much work into making and improving all the tools and software necessary to make this kind of thing even possible, I appreciate it!

I was on 3.0.5 when I got the device. Amazon didn't upgrade the firmware at all before sending it out, then I upgraded to 13.3.2.3. Why do you ask?
Hmm, I have now noticed that the kindle app is not working properly. I can sign in (though every time I sign in or deregister my account the app crashes) but it's not synching any of my books. They don't show up at all. The device (named android device 2 in the kindle app settings) does also not show up under my devices on amazon. Anyone know what the problem could be because this is a bit frustrating. Is this a bug with CM11 or with the amazon app?

Can't say definitively but I would lean towards CM11 as all Amazon apps (kindle/prime/shopping/video) work fine with the Nexus ROM (v2.0.5) which is layered on the same hw/fw base as CM11. Don't get me wrong; CM11 (and the devs who adapted to the HDX) are great! But there may still be a few hiccups with native Amazon apps.

Thanks for the opinion! I couldn't find any solution to the problem anywhere online and therefore just finished replacing CM11 with the Nexus rom, now the kindle app works perfectly fine and I'm very satisfied with what I've got. I will keep an eye out on rom development but for now I'm resting on my laurels :victory:. Considering that I was helplessly lost when I first came to the board I'm very happy with how smoothly everything went. But I really needed that step-by-step list I made and the assurance from the pros that it was correct, otherwise I would have probably made a careless mistake :silly:. Maybe it will be useful to a few other newbies as well. Not sure I will ever dare to fully unlock the bootloader like some suggested I might want to do at a later point in time, but we will see . Thanks again for the help!

Glad to hear everything is working well! My daily driver is on Nexus and I could not be happier. Everything works as it should. No need to unlock the bootloader unless you plan to do more modding. Enjoy your device!
Nice. I think everybody needs this kind of guide. Whenever a question is asked it just kind of trails off most of the time.
I'm still working on the downgrade piece.

Agreed, I was overwhelmed by all the different threads and possibilities at first. I ended up approaching it like any other research project for a paper or presentation and dumped every solid (and recent) piece of good advice into Evernote and sorting it out there. But writing and updating guides (especially with the fast development I have observed) would be a lot of work, I understand completely why no one would volunteer to do it and everybody would rather answer questions on a case by case basis.
First of all thank you very much! I was looking for something like this, since i am also new to rooting devices and this stuff...
I got a new fire hdx 7 with 13.3.02
I haven't tried anything yet, I am still reading threads and i got some questions here:
http://forum.xda-developers.com/kindle-fire-hdx/general/update-1314-4-1-1-probably-sangria-t2901813
-> I can only find 3.2.3.2 here, which is the firmware u used? Or did you mean another one?
http://forum.xda-developers.com/show....php?t=2665683
-> the second link for hdx toolkit isnt working
How do i get the playstore on my device?
are there anywhere more informations regarding flashify? since i have no idea what this is...
thank you!

First thing you want to do is block OTA (over the air updates) or your device may be upgraded by Amazon to a level that gives you less options. Suggest using HDX Toolkit (here) to both root and block OTA. Then install twrp (here). From there you can opt to replace Fire OS will several different roms including Nexus, CM11 or CM12.
Flashify is an app that allows flashing recovery and roms from from within Android vs adb or a recovery environment. You can grab it from the Play store or another market. It's a dangerous tool; use with extreme caution.
Be aware that any of the above actions, if executed incorrectly, can permanently brick your device with little/no hope of recovery (guess that's the definition of permanent). Read, read and read some more before taking any action. Be sure to keep WiFi off on your device until OTA is blocked to prevent auto-updates.

kindle fire hdx 3rd generation can't twrp

Hi
Newbie here. We bought a kindle which turnout to be blacklisted so we can't register it. Obviously it is useless as we can only use internet.
My kindle was running on latest firmware which meant I couldn't root it. Thanks to one of you xda geniuses. I was able to rollback to firmware 13.3.2.8
I change oat filed to avoid upgrades. I installed es explorer.
I then rooted my kindle and did root checked which confirms it is rooted on Kfthwi android 4.2.2
I installed su super user. Seems to work fine
After that I tried to install boot loader fireflash but it keeps stopping
I finally managed to install and launch Rashr but when I boot recovery with twrp or any other files my kindle boots and stops saying can't boot and offers me to do factory reset or starts again as if nothing happened. I haven't chosen factory reset as I don't think this will help.
I have added su super users to system hoping this would help but no success.
I have also tried loads of kfu from pc but although adb is ok it says boot status unknown and fails every time as if it can't find the path or something...
I have ran out of ideas. I don't know what to do anymore
My aim is to install cm12 or other versions... anything to make this kindle become android
Please help me!
Thanks

Hi I am sorry I misunderstood the terms. It is NOT blacklisted. It is unregistered.
We have called Amazon and it does not belong to anyone. We don't know how it happened we bought it second hand. The tablet is not letting registered but it is not blacklisted. Can you still help ?
You can NOT unlock the bootloader, use TWRP and CM12 anyway. You'd need 3.2.3.2 or lower for that, and you can NOT downgrade below 3.2.8.
Ok thanks for replying to me and for the info. So no more hope? I should just bin it?
So sad.... was supposed to be for my kids.
I guess this shows you really can't buy these tablets second hand!
Thanks again for your time.

You likely toasted the device by installing stuff that is not valid for a HDX.

Sorry for the prickly response. Reacting to: 1) device that will not register which is a bright red flag waving; and 2) installing fireflash which is for a different model and likely destroyed your device. You can not install twrp on a HDX that has been upgraded past 3.2.6 and you can not rollback to any version below 3.2.8 from any version above 3.2.6. A little reading would have quickly revealed the sensitivity of HDX models to 'hacks' other than the limited suite described in the forums. Your device joins countless others in the tower of bricks created by owners failing to research proper procedures.

Clarification

Warning: Potentially long post ahead with mini-intro/rant
Hi XDA! I'm a noob new user/newbie when it comes to rooting. I have some (little) experience with jailbreaking my iPhone previously (It turned out very well), when the guy I paid to do so practically bricked my old one (SHEESH, you can't count on other people to do these things, better do them yourself) but have not tackled rooting Android devices yet.
I have a 3rd gen Kindle Fire HDX 7" (Thor).
Don't get me wrong, I love my Kindle. It's been an awesome pal for the past two years, aside from the loose charging port, the lack of interesting stuff on the Amazon appstore, and the inability to change or customize YOUR device, I decided it was time to "get my feet wet". I've been coming back to these forums over the past few months, in hopes of finding a root for 4.5.5.2 but I'd always chicken out in fear of bricking it. Eventually, I learned that to root, I need to rollback to a certain firmware.
OKAY, so I've done a little reading here and there in the past two hours (or more) and have gathered the following information so far (if there's something worth clarifying or expounding, please do!):
Point 1: The steps are, in order: Rollback to 3.2.8, upgrade to 4.5.2, root, block OTA, install Safestrap v4, and (optional) flash custom ROM.
My options are CM11 and Nexus 4 as of the moment (from what I've seen on these forums, but CM11 has been discontinued[????] and there's a newer version of HDX Nexus ROM v4 called Fire Nexus ROM somewhere if I'm not mistaken)
Question: Which do you suggest? CM11 or Nexus 4? What are the pros and cons of each?
Point 2: I understand that I need to download everything in advance and store them in a unique folder so that it'd be easier for me later on.
Question: Do you recommend that I factory reset my Kindle before anything else and THEN download everything I need in preparation? Won't these downloads be deleted/removed if I rollback my device to 3.2.8? I'm planning on creating a backup of these files on my PC in case something goes wrong or missing.
Point 3: I saw something that said
It was only tested with 14.4.5.2, but should also work with 13.4.5.2.
Click to expand...
Click to collapse
Question: What's the difference between 14.4.5.2 and 13.4.5.2? I haven't dug deep enough in the forums to know if there's an answer to the question, but I made this thread to clear up everything I'm unsure of.
Point 4: Before anything, I know I've got to understand the basics of ADB before even attempting any of this (like commands and such). In one of the threads, I saw this:
"Install minimal adb + fastboot......"
Click to expand...
Click to collapse
Question: What's the difference between minimal adb versus the whole package/thing? Shouldn't it be better to just download or install the full thing (no matter how big the file/program/application is)? What are the pros and cons?
YES, I know I have to understand what USB debug means and/or how to enable it. (I bookmarked an article for further reading soon, but already have enabled the setting within my device).
Other things I've gathered so far:
-Always have a copy of ES File Explorer along with other important files.
Never perform a factory reset unless specifically advised to do so by someone experienced with HDX devices....
Click to expand...
Click to collapse
-Use a Windows PC/laptop. I'm using a mac, which is basically useless for games and the like not ideal when rooting. (Tiny question. Do I really need to install Linux/Ubuntu even if I can use someone's Windows PC/lappy to root?
-To root successfully, I've got to enable mock locations from developer options (already did).
-Before installing/flashing custom ROMS, I need to make a backup of the stock ROM.
CONCERNS:
Known issues regarding safestrap include secondary slots which boot but the WiFi module doesn't load (Which means I have to flash Nexus v4 to the STOCK SLOT for now [?????] is there any workaround for this? Because from what I've read so far, tampering with the stock is a big NO-NO unless you know what you're doing or in this case, "...unless I know what I'm doing.".) Or at least any reassurance? A safe, fool-proof way of doing this without at least bricking my device (likely)?
That's all I've got so far. I've compiled everything the basic things I need to know in a notepad, from steps and instructions, to tuts and download links.
Apologies for my english, this is not my native language
Thanks to whoever can answer some of my questions! Cheers and good day :laugh:
Don't even think about using safestrap, it might as well be a death trap if u brick ur device ur screwed. The best thing u could do is downgrade to 3.2.8 https://forum.xda-developers.com/kindle-fire-hdx/general/rollback-13-3-2-8-rollback-ota-captured-t3046204 unlock your bootloader https://forum.xda-developers.com/kindle-fire-hdx/general/thor-unlocking-bootloader-firmware-t3463982 (maybe get a tech savvy friend to help u with that one) it looks hard but it's actually very simple the way he explains it makes it more difficult than it really is. And if you want a stable rom with good user customization I'd get cm11. Also u don't really have to upgrade to 4.5.2 everything works great starting out from 3.2.8

Agreed. Be sure to stay off the network while on 3.2.8; if the device takes an OTA update it WILL brick with no possible recovey. Use TowelRoot to root; quick/reliable on FireOS v3. No need to update to 4.5.2; doing so adds risk/complexity with no corresponding benefit.
KingOroot PC edition (yes KingORoot not Kingroot) will root 4.5.5.2 in less than a minute, used it very recently having previously rooted 4.5.5.1 with Kingroot. In both case unlock the bootloader flashed twrp and put nexus ROM on without issue

Yes, kingOroot was previously identified as a potential root solution for 4.5.5.2. Sometimes it works...other times not. Kinda like KingRoot on the 5th gen Fire. When it fails the leftovers can be onerous to deal with on unrooted device. If root is secured I recommend immediately unlocking the bootloader following by a comprehensive wipe before flashing a custom ROM. KingOroot does not enjoy a stellar reputation.

NOOB HELP! Blacklisted Kindle Fire HDX 8.9 2014 OS 4.2 want to make it an Android!

So I need help badly! And of course, I've even asked if I could pay someone. I'm new to phones/tablets/android. Very comfortable with all things computer though. I bought the Amazon Kindle Fire HDX 8.9 for the second time off Ebay that Amazon did not want to register without a receipt from my seller's purchase. I wanted this tablet for the specs and also we do a lot with Amazon. I've been customizing my computer for years and I don't care the specs of the $50 fires that are coming out in 2017. However both my sellers were honest and gave me everything but their social security cards and said they had it registered in their name and called Amazon as well. It seems almost like Amazon is finding a way not to register these secondhand Fires that are discontinued without a receipt from the original owner for "security". So this is when I found out about rooting while googling my problem. I have the 4.2 OS. And I've read a lot of warnings about this particular model. Most of the advice is over two years old so I want to know what can currently be done to turn this tablet into an Android. Is it possible?
And can I get simple detailed instructions so that I don't "soft brick" or "hard brick" my device.
I got full refund from my first seller. The second one told me he would give me partial credit if I kept it and tried to root it. If it bricks he says he will refund me completely. He is under the impression that rooting isn't difficult.
Can someone please help me?

So I need help badly! And of course, I've even asked if I could pay someone. I'm new to phones/tablets/android. Very comfortable with all things computer though. I bought the Amazon Kindle Fire HDX 8.9 for the second time off Ebay that Amazon did not want to register without a receipt from my seller's purchase.

Device can be rooted w/o registering and install the custom ROM of your choice. But it will take some work, patience and tech experience. I can point you to the technical documents early next week if interested. Travelling with limited/no network access this weekend.

:angel: So I really appreciate the quick response, and you have renewed my hope for this situation. That would be absolutely great. I once had Linux OS on a used computer I bought and quickly reformatted so I could install Windows. I found it to be not very user-friendly. However, while I'm waiting for next week to come, should I study the Linux OS or is there anything I should read or concentrate on learning, off the top of your head, to make my journey a little bit easier? Thanks again.

Still Waiting to find out how to turn my blacklisted fire hdx 8.9 4th gen into a usable tablet. When I found out it was possible, I decided I would give it a shot and accepted $50 of the $130 I paid and kept it. Anyone who can help someone who is good with a computer, but I have no experience/knowledge with androids, I'm willing to learn if someone could point out the way. This particular model of tablet is supposed to not be easy to do, and please take into consideration my inexperience with this, I am willing to put time and effort if I could get the information/specific directions. I'm willing to compensate someone for their time. Please help.
Thank you, Wendy

Hi - as noted in my original response time, patience and some technical expertise will be needed to root the device via the 'bulk mode' approach. Unfortunately, time is not an abundant resource at present so you're pretty much on your own outside responding to specific questions. Below is the initial technical document which will undoubtedly seem overwhelming on initial inspection. You will likely want to read through the next few posts to adsorb guidance from the author (@draxie). Better yet, scan/search the thread for the word 'bulk' for related posts. Also see this post for links to a couple 'tools' that you will need to install on a Windows host before getting started. Good luck; ask questions as they arise.

I have done all the step in the link of bulk mode you post. It works very well with many KFHDX7 I have done but one of mine can't flash any ROMs although it can boot to recovery and bootloader. Could you help me?
P/s: It stuck at the white kindle fire logo after I flash any ROMs but I can boot to TWRP and fastboot.

Be sure to wipe storage before attempting to flash a new/different ROM:
- make sure the latest TWRP build is installed (link)
- boot into TWRP
- tap Wipe followed by Advanced Wipe
- tick all partitions EXCEPT 'Internal Storage'
- execute wipe (may take a few seconds)
- return to main menu and flash ROM of your choosing
- only ROMs customized for this device can be flashed
- some require a GAaps package and/or SuperSU; read ROM OP for details
If the above fails perform a comprehensive wipe that includes all partitions. Then reboot device into TWRP, re-download ROM and supporting packages and attempt to flash again.

I forgot unlock bootloader before flash ROMs on that HDX7. Do you think it made that problem?
These ROMs are work very well, because I flash 3 HDX7s by the same way with this HDX7 but there is no problem.
Please help me!

Wipe and flash this ROM. Work? If so proceed with bootloader unlock using Fire Nexus as a temporary base.

Great! You should now be able to generate an unlock code specific to your device (step #1) and unlock the bootloader (step #3), possibly with the help of these drivers to enable fastboot communications from a Windows host.
I flashed wrong TWRP file, and now my HDX7 couldn't boot to recovery or bootloader by press power + up (down) button and it stuck in white logo.

You're in a world of hurt if device can not be placed into fastboot mode via <power>+<vol-down>. Your may need to attempt a recovery via 'bulk mode' which is neither easy nor assured.

Sorry this happened. Bulk mode is the last option short of replacing boards.
