If vulnerable bootloader has been installed and fastboot commands are being accepted the unlock code is almost certainly incorrect or misformatted. Likely suspects include invalid inputs and/or prefix added to generated unlock code.

I'll admit it has been awhile since I unlocked any HDX and likely used an older Python based tool/technique. But the above 'errors' are what I saw most often and likely apply to the latest tool sets.
[Kindle Fire HDX 7" & 8.9" General] FELTRITE:
Ok, interesting.

So what do you recommend to do next?

find an older tool?

And I persume there is a legitimate way to get by this mechanism (Eventually some1 has to have the abillity to tweak with the recoveries)

is this a mechanism that is publicated to the community? or a vendor 'secret'

And god, thanks for the quick reply!

I'd also like to try out [MENTION=5828306]draxie[/MENTION]'s latest script (can i plz have a link? :D)
[Kindle Fire HDX 7" & 8.9" General] DB126:
I suggest you use [MENTION=5828306]draxie[/MENTION]'s script if you have access to a suitable host. You'll need to PM him to get a copy. See OP for guidance.

Doesn't work on mac high sierra. It says it can't install the VM.

Edit: Read me file lacks proper instructions. It says everything will be done automatically, but that's not the case with high sierra, but once you get the VM installed, the control panel is bugged. Message says to wait for the versions, but nothing gets updated for hours. You have to close the VM and open it again. Then it gets updated, but it only shows the info for the system while bootloader and recovery remain unkown. Not sure, this is the way it's supposed to be, but I'm not taking another step to risk bricking my device.
[Kindle Fire HDX 7" & 8.9" General] draxie:

I don't believe this for a split second. Can you post proof?
[Kindle Fire HDX 7" & 8.9" General] Verdinex:
Help? I've gone through all of the steps. I wanted to flash recommended rom by the op, and now I'm stuck at fastboot read option? How do I proceed?
[Kindle Fire HDX 7" & 8.9" General] DB126:
If you actually replaced and unlocked the bootloader you should be able to access twrp via <power>+<vol-up> (must power down device first) assuming all procedures were followed as described.
[Kindle Fire HDX 7" & 8.9" General] Verdinex:
No, I actually messed up horribly as I didn't add the bootloader and twrp. I don't know how I couldn't see it in the read me file :(. However, when I run ./fastboot devices command in the terminal, I get a number and fastboot. Is it possible to upload the rest of the files to my device via fastboot at this point?

Where can I even find aboot and twrp for Thor?

Edit: I have the rom, gpapps, root files on my memory though.
[Kindle Fire HDX 7" & 8.9" General] DB126:
Have no idea what source you are referencing as 1-click script should be self-contained. Start with this post in a long but very useful thread. There's a link to another procedure; start with step #6. Following that guide you will be able to replace the bootloader and install TWRP. However, you won't be able to immediately unlock the bootloader as you don't have the code. To do that you'll need to install a temporary ROM (suggest this one; fully self-contained) to generate the unlock code and finally unlock the bootloader.

You have a lot of work ahead. Read carefully, prepare thoughtfully and double check everything before executing. Acting recklessly will only lead to trouble; likely no one is going to bail you out. Good luck.
[Kindle Fire HDX 7" & 8.9" General] Verdinex:
This is what I have in 1click:

Enter fastboot (adb)

Enter bulk mode (fastboot)

Flash bootloader [?? -> 13.3.2.3.2/323001720] (bulk mode)

Flash recovery [?? -> TWRP 3.1.1-1 (forged)] (bulk mode)

Prepare flashing ROM [Fire OS 4.5.5.3 (455006120) -> AospExtended-v4.6-20180610-0939-UNOFFICIAL] (bulk mode)

Prepare flashing GAPPS [gapps 7.1 pico 20180721] (bulk mode)

Prepare flashing SU [Magisk-v16.0] (bulk mode)

Prepare wiping data (bulk mode)

Prepare unlock (bulk mode)

Unlock bootloader (fastboot)

Couldn't I just flash the rest with fastboot and use the 1_click then? I'm looking at that guide. So I need to enter bulk mode and this can be done via fastboot? It's the only way I can access its storage.

When I run the 1click again, it says under status that the device is unlocked and it recommends this:

Flash recovery [?? -> TWRP 3.1.1-1 (forged)] (fastboot)
[Kindle Fire HDX 7" & 8.9" General] draxie:
So, what's wrong? Everything you posted looks just fine...

Also, why are you asking for help with 1-Click here?
[Kindle Fire HDX 7" & 8.9" General] Azulath:
I have High Sierra as well and didn't have any problems.
[Kindle Fire HDX 7" & 8.9" General] Verdinex:
Thank you, draxie for your assistance. It turns out flashing TWRP did the trick and now I can fully enjoy Android 7.1 experience on thor. 5 star rating fully deserved.
[Kindle Fire HDX 7" & 8.9" General] DrFredB:
Great little utility. Was able to bring to life to my Fire HDX. Thanks again.

I did have a little trouble getting my kindle recognized, but that was due to low quality microsd cables.

Once I got the original cable my kindle was found straight away. I installed on a Mac Pro 3.1 running macOS High Sierra version 10.13.2

It was very easy to follow the process.
[Kindle Fire HDX 7" & 8.9" General] vartanarsen:
Thx Draxie'!! It worked...

Used my Mac to open one click. It took control and unlocked and rooted my hdx7! I thought it would never be possible. I then used TWRP to wipe my system and install Lineage latest and Gapps nano level(both zips I dragged and dropped into Mac Android Transfer app). After the installation on both zips, I cleared the cache and booted into lineage.

Everything is so perfect now, thank you so much...I was searching for days on how to do this. My final hangup is with the directv Now app which is not playing because it’s detecting my root. I tried the exposed installer + rootcloak app but it gave a warning about bricking so I backed out ASAP and uninstalled it. Any idea of how to evade root detection in 2018?
[Kindle Fire HDX 7" & 8.9" General] DB126:
Root cloaking is cat and mouse game that is increasingly difficult to 'win'. You can try SuHide if rooted with SuperSU. However, this tool is no longer being developed as is increasingly ineffective. Magisk is the other alternative with integrated root cloaking abilities. However, it is difficult to administer and, in some cases, unstable. If DirectTV is a priority I suggest you unroot your HDX which in no way will compromise usability or ability to upgrade/switch ROMs at a later time. Good luck.
[Kindle Fire HDX 7" & 8.9" General] vartanarsen:
Thx Davie... I don't want Root.. the only reason I needed it was to get to Lineage. Now that I'm here I could care less about Root. I'd like to avoid TWRP as much as possible and just work within lineage to Unroot. For me Direct TV Now > Root

Just getting started...

Hello all,

I am new to the forum and just wanted to say Wow! What a wealth of resources and talented people there are on this forum.

It is obvious the folks supporting others, and those writing scripts to help simplify certain tasks, certainly enjoy what they are doing - and isn't it that which gives us joy and is really meaningful in the first place?

Anyhow, I have been reading through the threads (here) for the last four weeks trying to sort through what is current and pertinent for my Thor device with presently available code. Needless to say, there have been many process improvements for expanding capability of our devices over the last five years - for sure.

Please wish me luck as I get started to improve the environment of my device which is currently running version 4.5.5.3. I have decided my first step is to begin with the "1-Click" process and use a Linux Mint as my host.

I will do my best to provide feedback and help others from my experience.

Thanks
[Kindle Fire HDX 7" & 8.9" General] vartanarsen:
Ok I’m such an idiot I didn’t do this the first time....2nd time..Went back to TWRP. Wiped system and installed Lineage, Gapps, and Magisk this time (first time, I did just lineage and Gapps). Wiped cache, and rebooted into lineage. Once in lineage , installed the magisk manager. Installed DirectV Now. Went into the Magisk manager and clicked on hide and put DTVN app,into the hide mode. Opened up DTVN and voila, all my 100 channels there :)))

Thanks to Davie, and Draxie for the Mac tool...you guys rock.

After spending a week at this I can’t believe my 2013 hdx7 has new lease on life. I can’t find one 7 inch tablet on the market that isn’t a crappy resolution...hdx7 was one of a kind.

To all newbies, ask me too now if you have questions. I am by no means an expert and considered myself a 3/10 skill level hacker. It was through the help of these guys that didn’t give up on me and helped.

You can Flash TWRP with a locked bootloader, then update the bootloader to 3.2.3.2 and unlock it.
[Kindle Fire HDX 7" & 8.9" General] rlkellyjr:
Hello Guys. I have a few questions about my Kindle Fire HDX 8.9 3rd gen. My kindle was rooted at one time, and at some point in the recent months I started having issued with the system looping at the start up screen (about choosing a language). I posted the problem here, and one of the members help me re-enable OTA updates. This was the easiest fix at the time, was to let the kindle take an update.

currently my firmware is at 4.5.4. Is there any root from this point, or do I have to go thru the downgrade process ? Also if I downgrade the firmware, will I have the ability to then unlock the bootloader, or had it been locked permanently since it took the current updates.

Thanks for any help our knowledgeable members can provide.
[Kindle Fire HDX 7" & 8.9" General] DB126:
Hello - believe I assisted you before. Quick responses:

- once past FireOS v3 (specifically xx.3.2.6) you can not unlock the bootloader

- to my knowledge Kingroot only works through 4.5.3; you'll need to rollback/upgrade to reroot

- review your post history to access the rollback/upgrade/safestrap guidence previously offered. The information remains relevant; nothing new has come along

- ask questions if uncertain; don't guess or assume

- Important cautions:

>> if you opt to rollback make certain your device remains in airplane/flight mode (WiFi off) while on 3.2.8. If you take an OTA update while on 3.2.8 your device will brick.

>> never perform a 'factory reset' unless advised by an experienced contributor (variable outcomes; some rather unpleasant)
[Kindle Fire HDX 7" & 8.9" General] matt101:
Hi,

My Kindle Fire HDX 8.9 (3rd GEN) is on 14.3.2.5. My bootloader is locked and 1-Click is not able to unlock. I'm trying to get TWRP installed so that I can safely get to 14.4.5.2. Is it possible to unlock the BL on this firmware version? Where should I look for details?

Thanks
[Kindle Fire HDX 7" & 8.9" General] DB126:
Bootloader can not be unlocked on 14.3.2.5; need to rollback to 14.3.1.0. See this post, steps #1 and #6 (ignore steps #2-5; for a different firmware version). After that you can flash 'native' twrp and use 1-click unlock.

Tips:

- remove Safestrap v3 if currently installed. Learn how do do this properly (don't just go uninstall)

- before rolling back verify native FireOS recovery is working (don't don't a factory reset...just make sure the recovery is accessible)

- if you previously disabled OTA you'll need to reenable to rollback; HDX toolkit can do this

- keep wifi off and airplane/flight mode engaged at all times to avoid an undesirable forced upgrade (OTA) from Amazon

- understand rollback involves risk that can result in a brick - follow instructions carefully; understand consequences

- backups are your friend; you'll regret not having them should something go wrong

Not sure I understand your comment regarding 14.4.5.2. Is your intent to runs stock FireOS or are you looking to flash a different rom? Most people want 4.5.2 to install Safestrap v4 which is not needed (nor desirable) if you can unlock the bootloader.
[Kindle Fire HDX 7" & 8.9" General] matt101:
Davey126,

Thanks for the awesome guidance, but I think it's bricked. Followed everything down to Step 6.8 and still received a downgrade error because the installed version was higher than the 14.3.1.0_user_310079820.bin. So I copied the build.prop from the rollback89v2 directory and replace the one in /system. After rebooting I get b/w Kindle logo screen than black screen. I have Kindle Stock Recovery, no fastboot, no adb access. I'm not sure if my error was writing over the original file or not setting permissions after overwrite, or both.

Anyway, thanks for taking the time to provide the downgrade information.
[Kindle Fire HDX 7" & 8.9" General] DB126:
Sorry for your loss. Messing with build.prop is risky on a locked HDX - as you discovered. Any deviation in expected permissions can lead to a brick. The downgrade error was due to an upstream omission which (you don't want to hear it) is easy to fix. Thanks for the follow-up; wish it had been a better experience for you.

For those who might stumble upon this thread: be sure to ask questions if you run into a problem. Most issues have been seen before and have easy solutions. This is an unforgiving device as [MENTION=1446615]matt101[/MENTION] experience demonstrates.
[Kindle Fire HDX 7" & 8.9" General] blackjanuary:
Does this rollback work on users who are on 3.2.8?
[Kindle Fire HDX 7" & 8.9" General] DB126:
No - you can not rollback from 3.2.8 to an earlier version. Attempts to do so will permanently brick the device. At present there is no path to unlock the bootloader from 3.2.7 and above.
[Kindle Fire HDX 7" & 8.9" General] blackjanuary:
Thank you for the very quick response. So I am unable to flash any custom ROMs at all correct? Sorry, but I am new at flashing ROMs.
[Kindle Fire HDX 7" & 8.9" General] DB126:
Path from 3.2.8 to custom ROM (limited selection):

- upgrade to 4.5.2

- root (two methods available)

- block OTA (over the air updates)

- install Safestrap v4 (emulates twrp)

- backup stock rom

- flash either of the following Safestrap compatible kitkat roms:

» Nexus v4 (ASAP clone)

» CM11 (needs no introduction)

That's the overview. You'll need to do some reading on specific procedures. The HDX forums are full of how-to posts including some nice user submitted procedures. As questions as you go along. Lots of folks willing to help.

As you probably gathered there are no newbie guides or helpful videos. All the information is here...you'll just have to dig for it.
[Kindle Fire HDX 7" & 8.9" General] blackjanuary:
OK so a little after I replied to your comment, my kindle suddenly turned off and said something about updates and it won't turn on now. I already had it on airplane mode with wifi off, so I'm not sure what happened. Just for some background, I had already rolled back to 3.2.8 from 4.5.5 and used kingroot.
[Kindle Fire HDX 7" & 8.9" General] DB126:
Kingroot requires a network connection. If you left wifi enabled an update could have slipped in. Bottom line is your device is likely bricked. There is no recovery (you may read about fastboot cables and other techniques for reviving bricked android devices; they don't work on HDX). Sorry for your loss.
[Kindle Fire HDX 7" & 8.9" General] avaholic:
Thanks for your work! I have successfully rolled back my hdx 7 to 13.3.1.0. It also appears that safestrap is now gone as I no longer get the prompt to boot into recovery or to continue. Is that expected behavior going from safestrap/13.3.2.4 down to 310??

I ran your batch file on Win10 Pro x64 and it creates the vm in my user directory and then tries to run vbox. (VirtualBox is already installed as I use AndyOS for testing on my PC and it uses Vbox as well.) However, it immediately pops up "VBoxHeadless.exe has stopped working" with the only option being "Close Program." When I click close program the batch file cmd window is still open but nothing happens. Note I tried running the batch file as Admin with the same result. Any ideas as to what could be going wrong?

Would it work for cyanogenmod?

Hello, I have a kindle fire hdx Apollo, using cyanogenmod 11-20150331-NIGHTY-Apollo ANDROID 4.4.4.

Can I use this method safely? Thanks.
[Kindle Fire HDX 7" & 8.9" General] EncryptedCurse:
What FireOS version did you come from/ what was on it before you flashed CyanogenMod?

If you're not sure, are you using TWRP or Safestrap?

There's no risk with attempting a bootloader unlock on any device, but it obviously won't work if you don't meet the prerequisites (a 3.2.3.2 bootloader).
[Kindle Fire HDX 7" & 8.9" General] JJAVIERMD:
Great!

I don't remember the exact version of fire OS I had before rooting and flashing cianogenMod, think it was early version though.

And yes, I'm using twrp recovery.

Nice device that's getting a bit long in the tooth. Best live with your "liberated" HDX for a few weeks before investing in a 5 year old platform. Batteries are nearing EOL with replacements difficult to procure/install. A 7" HDX remains my daily driver but the gap is narrowing given the capabilities of contemporary hardware. Panel resolution and color temp remain the most distinguishing characteristics - especially at current price points.

Just an update to let you all know things went well with the Thor 4.5.5.3 update!

I must say that I am extremely impressed with what Draxie and many others have graciously and collectively provided our group. The programming and interface are indeed "5 Star". The outcome was the next best thing to sliced bread! Thank you Draxie and all those who put in countless hours to help craft this effort!

Not to say this is an easy task for the end user - even with all of the tools at our disposal. I put allot of personal time into reading and properly preparing so I could understand my product, what has been learned and shared up to this point, and configuring my specific host hardware and platform environment for the task. This is why there is no cookie cutter method, or quick 10 step process, to document and release to the forum. Everyone will have different PC hardware and operating platform versions to consider as well as different tablet/phone hardware and software.

The end result: I now have a configurable OS for my Thor that will allow seamless integration with Google Play Store and likely provide years of additional use and undoubtedly better experience of the device.

Incredible! :cool::good:
