[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Assume your goals are:

- fix problem with existing Google Play Store/Services install running on rooted FireOS 13.3.2.1

- believe problem can be resolved using file/folder permission tweaks issued via adb in TWRP

- retain existing FireOS install (look/feel)

- retain existing user data

With the above in mind TWRP can be installed (flashed) with no changes to your device -and- without unlocking the bootloader. Keep in mind any flash operation involves some risk due to the nature of the task being executed. That said, the risk here is very low...just not zero.

Procedure:

- sideload Flashify 1.9.2 from here

- launch Flashify and backup existing recovery environment (kernel optional); copy small backup file to off-device location for safe keeping (email to self)

- download TWRP 2.8.7.0 (older version) from here; if possible verify checksum (MD5) of downloaded file

- use Flashify to install above image (.img) file

- launch TWRP (assume familiarity with procedure and UI); backup existing FireOS install; copy folder (not individual files) off-device for safe keeping (you'll need to do this via tether)

- use adb to make desired changes

- once all is well consider removing on-device TWRP backup folder if free space is concern

Please do not ignore suggested backups; you (and your daughter) will be an unhappy camper should something go wrong with no fallback. Also be sure to flash the recovery image to the recovery partition. Installing to the boot partition will fatally cripple the device.

Oh Geez!!!! I guess I'll have to hold my breath while doing all of the above!!:fingers-crossed: Thanks Davey for such a thorough answer. If I get up the nerve, I'll post back:silly::eek:

I found these files last nite when I figured that this was the way to go. If I had gone ahead, I wouldn't have thought of backing up all the stuff you suggested. So thanks there.

When I went to DL the file, this is what I read-

signed-thor-twrp-2870.img

for the Amazon Kindle Fire HDX 8.9, by ggow- This made me pause? Typo??
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] sashusmom:
OK. Flashify is on the tablet. I put the twrp image on the root of the tablet. I backed up the Stock recovery and kernel. My options to save was sd card. Did that, but can't seem to find the files, even with file explorer. Re-backed up to my dropbox. Still can't find the files. So I am stuck till I find them. :( I won't quit. There is not option to email....So Still looking.

When I backed it up, it took 2 seconds. Maybe it isn't working? I don't know.

Found the back up files with file explorer!!:D Still creeping with baby steps here.:fingers-crossed: Bear with me.:silly:

---------- Post added at 02:53 PM ---------- Previous post was at 02:25 PM ----------

So I saved my backups. I found the file twrp to flash with flashify, but I don't see the option or choice to flash onto the recovery partition, it just says flash? yup or maybe not. Is the choice for partition on the next step after yup? ( geez- so americany slang!!)

"Please do not ignore suggested backups; you (and your daughter) will be an unhappy camper should something go wrong with no fallback. Also be sure to flash the recovery image to the recovery partition. Installing to the boot partition will fatally cripple the device."

Holding until I get clarification on flashing twrp via flashify. I do not get the option to choose a recovery partition to install on. All the you tube vids I watched, you just hit the yup button and flash it.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
As long as you tapped "Recovery Image" (not Boot Image) in Flashify you're good to go.

If I can't get this to work, I may have to try to unlock the bootloader. And tell daughter she will have to reset up her tablet with a custom rom.

So far, in my reading I have the Unlock file in the folder with minimal adb and fastboot tools, with the unlock code already generated so the unlock file has 6 files instead of 5.

How much more is there to it? TWRP is now on the tablet- version 2.8.7.0. with the firmware version of tablet at 13.3.2.1_user 321093620
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] addheat:
Bought an hdx flashed with cm12.1 (thor) and after months of use battery had been decreased drastically. This possibly due to my daughter loves to install/uninstall new game and don't like what possibly she installed.

Wanting to factory reset. Can I go down to the route of setting > factory reset or do I have to do something differently? Thanks for the help!
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Should be able to reset via Settings -> Backup & reset -> Factory data reset. Heed the warnings; everything goes (including game progress) unless specified otherwise.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Sorry for delayed response. If I understand correctly you have already executed step #1 (or its equivalent) from this post and have a file named "unlock.code" in the folder with adb and fastboot executables. If accurate proceed as follows:

- tether device

- boot into TWRP

- from the TWRP reboot menu boot into the bootloader

- verify you see the word 'ready' on the HDX screen (if not stop)

- from your host issue the following command: fastboot devices

- verify you get a response to the above command (should display device serial number)

- if everything checks out run 'unlock.bat' from the host'; should get a green 'ok' on HDX

If something doesn't check out please detail the action and response; we'll go from there. Otherwise post back and I will provide some guidance (opinions) on migrating to a custom ROM.

Thanks Davey. :D Unfortunately had to go 800 miles south and no longer have possession of the tablet. I will get back to this thread in about 3 months to let you know how it went.;) thanks for all your help.

Having issues knowing where to start. I have a stock HDX Thor operating Fire OS 4.5.5.3. Do i need to root this first, as I've seen many people saying it doesnt. I have been searching the forum for 3 hours and I just dont want to brick this thing. Help is appreciated.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
There are two paths to unlocking the bootloader, one assuming root is available, the other not. Suggest the former unless quite comfortable working with adb, fastboot, etc.

While borderline malware KingRoot is the tool of choice for rooting FireOS v4. It often takes a few attempts; just keep trying. Can always fall back to the 'no root' method if Kingroot fails to deliver.

Spare Motherboard

Hello,

I have a spare HDX 7 motherboard and wondering if anyone have a hardbricked device that they longer require?

I would like to purchase your bricked tablet.

Preferably from the United Kingdom.

[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] fillippouk:
Thanks Davey.

I have been wondering what folks do with their bricked Kindle.

Am seriously willing to fix it for free but I'll seek to get one elsewhere.

Does anyone feel like the HDX7 is still a decent tablet with its 2.2ghz cpu, 2gb ram and 323ppi screen density?

With a custom rom installed it beats most 7" tablets imo.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Still an amazing value at current auction price points. Really nothing in its class as mid-range tablets have fallen out of favor; no competition to moderate prices. My HDX7 remains my daily driver for transactional content consumption and limited creation (email, XDA, etc). I use Amazon's low end gizmos or burner phones for media consumption. Moto E4 from Walmart is only $40 USD and smokes most budget phones. I don't bother to activate, just use as a WiFi device with stock Nougat ROM. Handles just about everything in a nice compact profile.

Looking for some advice on installing custom Rom on HDX 8.9 Apollo.

Hi I have just bought a second hand HDX 8.9 Apollo. I love this tablet but it is way to restricted. I have sideloaded some games and they won't run due to Google play services not being compatible etc, and its frustrating me that I can't even play a YouTube video in full resolution. I am looking for some advice on what is best to do. Can I root the device and install Gapps or am I best installing a custom Rom and replacing Fire OS? I am currently on fire os build 4.5.5.3. Any help will be greatly appreciated.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Your best bet is to unlock the bootloader and install a Nougat based custom ROM (multiple choices). While it is possible to root and/or install the Play Store FireOS v4 and GApps simply do not play well together. You'll also find FireOS rather limiting relative to other Android ROMs although it does have a few 'pluses' that some appreciate. Once unlocked the device is liberated from Amazon and remains competitive with the best Android tablets on the market today. Not bad for a 5 year old design.

Be aware the unlocking experience is not for the faint of heart. Forget about what you may know from previous experience with Android gizmos. Amazon devices are unique beasts with unique procedures that must be carefully observed. You will need to do a fair bit of reading in the relevant XDA forums (most other sources for HDX moding are either obsolete or simply wrong). Be prepared to fail a few times and possibly have to dig out of a deep canyon with steep walls. The experienced (albeit shrinking) HDX 'expert' community is willing to help but you'll still need to do some heavy lifting.

An overview of the unlock procedure can be found here. A couple recommendations:

- download/install Minimal Fastboot and ADB vs the tool(s) suggested in the linked post

- if tethering to a Windows or Mac platform you will probably find Motorola drivers (here) perform better than those provided by Amazon

Keep reading; ask questions when you are ready.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] jedimaca:
Thank you Davey.

Thank you for the advice. I have some experience with unlocking bootloaders and installing custom Roms. I think I am going to give it a go at the weekend. Thank you for pointing me in the right direction. This is greatly appreciated.

Edit. Just managed to unlock the bootloader and install [ROM][7.1.2] AospExtended. Followed all the instructions to the letter and have stock android running on my HDX, worked a treat first time no problems. Very happy with my device now. Thanks again Davey and all the developers on XDA.

Pointless but contextual backstory

So two or three years ago, maybe longer, I installed whatever the latest version of CM at the time was on my tablet, 11 or 12 I think. After that it fell out of use pretty quickly, probably because the keyboard app crashed continuously every 5 - 15 seconds with an annoying popup based on my usage of it yesterday and I had no clue how to restore the original OS (not that I really want it.)

Relevant backstory

So I found my Kindle yesterday, threw the Apollo edition of LineageOS released like two weeks ago onto it's internal storage along with what I believe was the correct version of open gaps & SuperSU. One reboot later I was at TWRP v2.7.1.0/Safestrap Recovery v4.01 and wiped all the partitions (which apparently doesn't include internal storage), and tried to install everything.

It booted to the stock recovery menu instead of what I'd hoped to see, after I think three failed installations I gave into my curiosity and tried to reset it from there. That was a bad idea.

My problem

After using the stock factory reset I can no longer browse the internal storage via Windows or Linux file managers, I do however still have adb access so I haven't really lost anything but convenience, and I still have access to TWRP/Safestrap.

From there I've tried everything I can think of, LineageOS will 'install' but I get booted to the stock recovery screen, so I imagine it's not working, I tried updating TWRP to 3.1.1-1 and learned my bootloader is locked (I'm at a loss to how I flashed TWRP the first time around if that's the case), and of course I tried unlocking my bootloader, that has not gone well, apparently the unlock.code files I've been getting are invalid.

So perchance is there anything I can do, or have I soft bricked my device?

TL;DR

Longer tl;dr I failed at installing LineageOS somehow, got frustrated/curious and tried a 'Reset to Factory Defaults' in stock recovery, things went wrong, but I do have adb access & access to TWRP, but my bootloader either was never unlocked or was re-locked by the reset, I imagine the latter, and refuses to unlock by the recommended methods (various versions of Cuber).

TL;DR was TL;DR

Tl;dr bootloader is very locked and will not unlock & other problems probably resulting from that.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Device never had TWRP installed (flashed). You previously loaded Safestrap which is a TWRP emulator that lives in the system partition. Amazon's stock recovery (which really isn't) remained in the recovery partition. When you used that to 'factory reset' the device Safestrap and the TWRP emulator were vanquished. Since the system partition was altered to accommodate Safestrap FireOS won't boot. Nor can it be restored/rebuilt/reinstalled via Amazon's neutered HDX recovery. "Soft bricked" is an appropriate descriptor.

I left out some niggling details that will annoy purists but the highlights are essentially correct.

Best course of action is to install a vulnerable bootloader that can be subsequently unlocked. Once accomplished the full suite of custom ROMs for this device is at your disposal. Two paths:

- use the 1-click unlock method/script if you have access to a OS X (Mac) or Linux host; Windows and Windows virtual machines are NOT supported

- manually erase/replace aboot as described in this thread; many have found this post to be a helpful starting point

If you go with option #2 you'll probably need to temporarily install older TWRP (2.8.7.0) and ROM (Fire Nexus KTU84Q) images to generate the bootloader unlock code.

There are other approaches to restoring unlocking the bootloader (restoring functionality) for those that prefer to blaze their own trail; I'd advise against pursuing unless you have copious technical experience, gobs of free time and view your device as fully expendable.

Best of luck.

Hi. My kindle fire 3rd gen was never rooted or anything. I have the update 4.5.5.3 unfortunately. It updated before i managed to stop the updates. I tried searching for ways to root/downgrade, but had no luck. Might be because English is not my first language, so not sure If I was searching correctly. Could anyone point me in the right direction for rooting a KF with the update 4.5.5.3? I have it almost since release and would like to breathe some new life into it.

Well. I cannot boot into fastboot. Using "adb reboot bootloader" just reboots the device. I did some searching beforehand and my guess is I need the factory cable?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Hum, that command should work even on an unrooted and/or bootloader locked HDX. I don't have an immediate explanation. You could try powering down then restarting via <power>+<vol-down> button combo. However, that technique generally will NOT work if the bootloader is locked.

So called "factory cables" are generally useless on this device except in special circumstances. Where were you seeing instructions to use such a cable?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] Gruby4D:
---------------------------------

As for the factory cable, I saw a lot of posts about it, so can't point to anything specific. Lots of posts saying that it causes the device to reboot to fastboot if connected when you connect it and then power it on. Saw all of them on xda. Pretty sure I saw at least two where people claimed it works on 3rd gen kindle.

I restarted like 30 times before posting, trying different orders, reinstalling drivers etc. Everytime, the kindle just reboots. Tried using kingroot (yes I know its malware, would remove it after root by flashing a rom or sth), but I get a network error and have to click the back button every second to progress the % and it goes up by 1, just to say at the end that the root failed, so ye. Not sure what that network error is about, couldn't find any fix for this.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
If your goal is to get to fastboot I suppose a 'factory cable' might do the trick. Low cost and essentially zero risk to device improves the appeal. Kingroot behavior is also odd. Wonder if the device (firmware) has other issues. Good luck.

I don't really know this device very well, but I would reflash the firmware, same exact version that is currently on it.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Unfortunately, not possible on this device when unrooted due to lame stock recovery that lacks sideload support.

[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] Gruby4D:
That's a bummer :rolleyes: Not sure what to do in that case :/ I tried using a command from a post that would stop the temporary fastboot when rebooting and allow me to stay in it, but the console just says "Waitinf for the device", and the kindle reboots.

Soft bricked Amazon HDX 8.9 (3rd gen.). Stuck in fastboot mode. Any way I can save?

Hi All,

New to this forum and new to the HDX series. I've literally spent like 7 or 8 hours today searching through the posts trying to unlock the bootloader and install twrp. Was trying all sorts of methods. Using fastboot I kept on hitting a roadblock when it would basically say can't do blah blah blah on a locked hw. I then decided to try and install twrp without the computer. I had it rooted with KingRoot then I downloaded superSu pro and flashy to do it. When I flashed the twrp image it said flashing successful, do you want to reboot or flash more things. I did reboot and it just got stuck on logo screen. I did a hard power off and from that moment on it will only boot to fastboot/bootloader mode. Is there any way to salvage my HDX? I apologize in advance if this has been addressed elsewhere. Every post I found related to it didn't work for me. Thanks in advance for all your help.

Adam

While I don't know what the issue was that was blocking the bootloader unlock, flashing twrp likely made the tablet unrecoverable.
