Recommend installing drivers from this post which seem to work better than many of the other drivers...especially for fastboot connectivity.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] raybender:
Thanks for the help,

I tried the adb command and with the su part and it gives me the "unallowed user" error. If i do it without the "su -c" it gives me "/system/bin/sh: idme print unlock_code\: not found"

Any suggestions about how to go about unlocking the bootloader, if at all possible? Thank you
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
See this post. Don't forget to install the drivers referenced earlier in this thread.

I recommend starting with step #2 which can be performed independently from the other two steps. However, you'll probably find the associated links are not working. You can grab the vulnerable aboot from here. Once that is complete download Flashify from here, install on FireOS and then use that utility to install TWRP from here. A TWRP image can also be installed from fastboot if you are comfortable operating in that environment.

Lots of links to different threads. Sorry about that. Have on my to-do list to create a new thread with all relevant information/tools in one place. Unfortunately, other priorities in real-life take precedence. Until that happens the above resources should be sufficient.

Rebooting at logo after encryption attempt

Well, Im back again. I had everything going well with lineageOS but i had to encrypt the machine, now all it does is keep rebooting after the while kindle fire logo. I can still get into twrp. i tried doing a wipe of everything and starting all over (system, dalvik, cache, internal memory, data) but after intalling LOS, It still keeps rebooting again. Would i have to redo the whole thing again by installing FireOS and will that lock my bootloader again? Or am i screwed now?

Thanks again for the help.

I know see that encryption is not working on the LOS rom.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
A full wipe should have removed all Lineage remnants and permitted reinstallation. Suggest installing a basic KitKat based ROM (here) to assess your devices stability. If that works wipe primary partitions (system, data, cache, dalvik) and try Lineage again. Might also consider AOSP Extended (here) as an alternative to Lineage.

General Guidance and Rooting

Hello, I am new to this forum and new too rooting android devices.

I have a Fire HDX 7" 3rd gen device running FireOS 4.5.5.3

My end goal is to replace FireOS with Android (closer to stock, the better), with preference of best compatibility with the hardware. The newer the Android OS, the better.

My current goal is to root it.

My general problem is that it's rather difficult to sort through the info provided. This site has plenty of resources and links, but very difficult to find a clear step-by-step guide. And it's difficult knowing what applies to my device and its OS, and what information is outdated.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Three major steps:

- root (most use KingRoot)

- unlock the bootloader (related thread)

- install a compatible ROM; recommend AospExtended which is a stable, pure Nougat based ROM with a nice suite of optional extensions

Unfortunately, your lack of experience is a significant obstacle. Suggest trying to root as you will gain immediate benefits in FireOS even if you choose not to go any further. If that works out ok we can take the next step.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] spook6:
Very helpful. Thank you.

Within this second step, I am stuck at:

with a 404/dead link.

However, searching for TWRP on this site, I was lead here: https://twrp.me/Devices/Amazon/

Neither of those devices are the Kindle Fire HDX 7" 3rd generation, but I wonder if any would work nonetheless.

I am determined and careful

Hey guys, everything worked like a charm, except the fastboot driver at Windows 10. I installed several driver packages, in the end the regfile in this Thread in combination with a reboot helped me out. Thank you very much!

Nice find. Establishing communication with HDX devices at the fastboot level is always a challenge (at least with Windows). Good to have another resource. Thanks again for sharing.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] skrobul:
hi, I have fire hdx 8.9 4G (KFAPWA) and I'm trying to put Nexus ROM on it. I was running newest firmware 4.5.5 so I followed guide from the other thread.

I managed to roll back device to 3.2.8, then an upgrade to 4.5.2.

i then downloaded and installed newest version of Kingroot and tried to use it. Unfortunately all it does is spin the wheel for good few minutes, reboots at 16% then spins wheel for a bit longer and finally says "root failed". i have tried doing this initially with wifi on very briefly just to satisfy kingroot, but eventually amazon OTA caught up and I'm back to 4

5.5. I know I will have to repeat procedure, but was wondering if you have any suggestions as to what I can do differently this time in order to get root?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] sd_shadow:
I would try a different kingroot version (like 4.50), once you download kingroot, turn on Airplane mode, so it doesn't upgrade
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Kingroot failures are uncommon but not unprecedented. I suspect it will work fine on your next attempt (sorry you have to repeat the rollback/upgrade procedure). If you experience further difficulty there is another rooting option which is a bit more challenging but gets the job done. Recommend trying Kingroot first, possibly going with a previous version as suggested by [MENTION=4267571]sd_shadow[/MENTION]. You'll still need to briefly enable network connectivity for Kingroot to work its magic; 30-60 sec max.

Flashed kf 7 on kfhd 8.9

Am I dead? Can't get it into fastboot, just the kindlfire orange animation.

I'm familiar with fastboot. I was able to get it there many times, but after flashing the wrong recovery, it just hangs.

I'm wondering if I go through everything for the soupkit install with linux if that's going to help.

Everything I've read says if you can't fastboot, you're dead with the 8.9?

Thanks!
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] skrobul:
Thanks for response guys! Forgot to mention earlier, but I tried different versions - always with same result. Anyway, yesterday I attempted to do whole cycle again, but this time Fire died during the upgrade from 3.2.8 to 4.5.2. It displayed progress bar, went all the way to the end, then screen turned black. I made several attempts to fix it (charging for hours, holding power button for 30 sec, VolUP + power and all other combinations) but there was no reaction whatsover. So, I tried connecting it to the computer and checking if I can log in with adb or fastboot cable. No response at all, so I contacted support and returned device.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Sorry this happened. Rollbacks/upgrades are always risky - even those fully scripted by Amazon (stock). As you learned through misfortune the HDX is a temperamental device. Beautiful hardware crippled by a neutered variant of Android and supporting low level components. Those who make it through the root & rom process are richly rewarded with arguably the best experience on a sub $200 usd device (entry point; some varients are obviously more expensive). A nice HDX alternative is 2nd Gen Nexus 7 if you're looking to make another go of it without having to deal with Amazon.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] skrobul:
Yeah, I guess it can happen on any device really. Thanks for recommendation, i actually decided to spend little bit more money this time and just purchased nexus 9. I had nexus 7 (first gen) before and was quite happy with it. I'll keep lurking on this subforum though, still have other kindle fire soho to unlock [emoji2]
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Possibly not. Making it past the grey splash screen suggests the rom started to load but hung.

Which ROM or version of FireOS? Safestrap installed? Was adb enabled at the OS level? Assuming device is rooted.

Which recovery did you flash?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] KWY_73:
Answers

I used the KFHD_SRT v 1.2 to flash the recovery with root. Device was rooted and adb enabled. When I first plug it in to the computer, the ADB drivers flash for a second then disappear again.

My other kindle fire hd 8.9 is rooted etc but I did it several months ago, and works just fine with the adb drivers and windows drivers work as well.

I got 1/2 way through the same install but figured out I didn't put the new mod on the device before I got well into the twerp recovery. So I wiped the old one and didn't have a new one. I had saved to recovery, but I couldn't get it to load. So I started searching around.

I was stuck at fastboot mode until I found the utility. I'm sure if I had only used the v 2.1 I would have been fine.

v1.2

http://xdaforums.com/showpost.php?p=33156486

I currently have kffirstaide64 installed, but until I can get back into fastboot mode I don't know what to do.

direct answers as best as I know.

Which ROM or version of FireOS: Whatever the stock os was. I don't remember the version I planned on wiping it. I never got a ROM installed.

Was adb enabled at the OS level: Yes

Was device rooted: Yes

What did I flash: I tried to flash the rocovery with root for KF 7. And I'm afraid I was successful.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
HDX is a very different device than HD. Thoughts:

- you are posting in the wrong forum (try here)

- you attempted to apply a HD solution to a HDX

If the latter there is little hope for recovery given the state of your device. BTW - Unlike other devices (including HD) fastboot is useless on HDX models with a locked bootloader. Ditto for 'fastboot cables'.

Alrighty, I've been searching for how to do this but can't find the thread anymore.

I have a rooted 7" that I need to go back to out of the box stock. I haven't played with it in a long time, but I remember the update.bin needs to be at the root of the sdcard(?). But with the ota system killed it doesn't seem to work. So I'm a little lost..

1: you have a Kindle Fire HDX 7" 2013?

The Kindle Fire HDX 7" has Power and volume buttons on the back. Front-facing High Definition camera

2: Safestrapped, regular TWRP recovery, or neither (Stock recovery)

3. Rooted stock or custom rom?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] airplane_guy:
3rd generation, which I believe is 2013. Stock recovery, rooted stock with Google play. It was factory reset by my girlfriend so setup is stuck at the initial play setup then goes to kindle settings with no software buttons to go anywhere else

Edit- running 4.5.2
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Removing root will not fix this condition nor is there an easy way to return to pure stock without additional info. What version of FireOS are you running and had you taken steps to block OTA updates? If so, which method or tool was used?

---------- Post added at 01:02 PM ---------- Previous post was at 01:00 PM ----------

Edit: just saw your updated post (4.5.2). Tough nut to crack. Do you have adb access?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] airplane_guy:
I'll have to check adb later. I'm away from it. But I assume since I can access settings I can turn it on. It's been months since this tablet has even been charged so I think the method was, rollback and then update with a modified ota, then file kill ota.

With the toolkit that's out now, can I simply re-enable ota and take it?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Not sure which toolkit you are referring to. The one I am familiar with (HDX Toolkit) is for FireOS v3 and won't work on v4. As you suggested one approach is to find the OTA module (located in /system/priv-app/) rename it to DeviceSoftwareOTA.apk and then hope your device accepts and successfully processes the latest FireOS update (likely 4.5.5 which is not rootable). However, there's no guarentee this will work and some level of risk as you system partition contains non-standard components.

Another approach involves installing an alternative launcher (eg: Nova) via adb which may allow you go gain sufficient control over your device to locate/rename the OTA file or remedy the problem another way. There are threads/posts in the HDX forums discussing others methodology and success/failure with this approach. You'll need to to a little digging to find them or perhaps someone else will post a link.

Another user installed/configured Safestrap v4 via adb. He was then able to reflash a custom version of FireOS v4.5.2 (here) which essentially returned the device to stock. Again, you would need to do some searching to find the relevant posts.

In all cases you need both root and adb access. Hopefully 'usb debug' was previously enabled or you can toggle it from the FireOS settings menu.

If the device is still under warranty you should seriously consider asking Amazon for a one time exchange. Most are successful with this request provided it is still eligible for exchange. Amazon does not appear to check the device history. Simply state the facts: following a factory reset the device hangs at the settings menu. No need to go into further detail.

Good luck.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] airplane_guy:
Well, usb debug is on, drivers installed correctly, adb doesn't recognize the device. The rollback methods don't seem to work. Without a "home" button, I can't get into the launcher, and, this kindle was already exchanged through Amazon once.

So without adb recognizing it and no safestrap, I feel like I'm out of luck. Yeah?

Theoretically any of the AOSP based ROMs should work including Nexus MM, AospExtended and Lineage to name a few. So far no one has explicitly said a modded HDX seamlessly passes SafetyNet so you'd be doing a bit of trailblazing.

Noob questions

HDX 7 running 4.5.5.3

1) Can an alternative launcher be used and not have the tablet ask each time which launcher to use? (I had tried in the past and nothing fixed that issue)

2) Can 4.5.5.3 be rooted?

3) As someone who likes Amazon's carousel (hence why I'm running OS4) are there any hacks or custom roms that are built on it that may speed it up? (speed is my issue.)

Thanks!
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
- there are no launcher prompt workarounds on FireOS v4

- 4.5.5.3 can be rooted and bootloader unlocked without removing FireOS

That combination give you freedom to be more aggressive around suspending the default launcher; if something goes wrong you can restore your previous working config via TWRP (assuming you backed up in advance).

You speed issue is almost certainly related to FireOS V4. A 3rd gen HDX is wicked fast (responsive) with the proper ROM. I am penning this on a 7" HDX running AospExtended based on Android Nougat (7.1.2). Lag is non existent. Not the best gaming platform (aging GPU) but everything else runs fine.

Once rooted you can systematically freeze or disable Amazon/FireOS apps and processes that are contributing to the slowdown. You can gain a lot of speed that way with minimal/no side effects. Also important to unlock the bootloader (or at least install a 'vulnerable' bootloader) as recovery is nearly impossible without access to a custom recovery.

Good luck.

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

Thor 4.5.5.3 Rooted?

I have done a ton of research on rooting the Kindle Fire HDX (KFTHWI) on OS 4.5.5.3 (I gave up about 4 months ago.) Today, just for S&G, I tried using KingRoot V5.3.1.441, and the device rebooted three times. Now it says its rooted, and the SU prompts come up. I thought it was bogus. Yet all Root Checking apps say its rooted. Did I give up (4 months ago) just as a method was found? Has anyone else rooted the KFTHWI on 4.5.5.3?

I skimmed through the forums, and all posts I've seen say the 4.5.5.2 had to be downgraded before rooting. Can someone suggest a bootloader unlock / custom rom for this model, on that firmware? I'm sorry if I missed a post that is clearly visible. I'm dumbfounded at the idea I can actually have a regular android experience on this device.

:confused: :fingers-crossed:

Hi all and Happy New Year! Can't believe it is 2018 :) I got this HDX 7 Thor fire tablet in 2013/14, when it was fairly new, set it up for my daughter, and it is all her stuff on it. (She is an adult but doesn't do techy stuff). It is on 13.3.2.1 with a build date of 2/6/2014. I rooted, blocked OTA updates, and put on google services apps (the 4 apks), and she was good all these years. Google stopped working once but I fixed it.

Now, with their last update, google is blocking services due to improper installation- due to root, or other unauthorized installs (which we have a hacked install) and won't update apps, or download new ones. I looked up how to fix it, and it said to turn on all toggles for permissions on google play and google services, but our rom is so old, we don't have toggles to turn on.

The article is here-

https://www.siusto.com/google-play-...ents-users-from-downloading-or-updating-apps/

The alternative way is to use adb which I have been trying to accomplish with these commands;

adb shell

chown -R media_rw:media_rw /data/media/

find /data/media/ -type d -exec chmod 775 {} ‘;’

find /data/media/ -type f -exec chmod 664 {} ‘;’4)

I have adb shell when I am NOT in recovery- (stock recovery). When I go into recovery mode to use the above commands with the minimal adb and fastboot commands, the tablet and device drivers are not recognized, with a error code of 45(device manager), disconnect and reconnect, but it does not go.

What I want to accomplish is- Not lose her stuff, and get google services working again. What's on there works, but no new apps or updates can be downloaded. This bootloader is still locked. I am still rooted. She won't be a very happy camper if I lose her stuff or am forced to erase it.

Is there an easy way now to unlock the bootloader? Put on TWRP ( will that get adb working using that recovery?)

I got a cheap HDX 7 to practice on, but it was already bootloader unlocked when it arrived with a ggow custom rom on it- kk-fire-nexus-rom 10/17/2016. So If I screw up, there goes her tablet, and hers is the 32 GB model.
