Hi [MENTION=6166688]ckwylde[/MENTION] - time continues to be in short supply. Please take a look at the following two threads for further guidance - especially the OP (first post) in each. A few additional tips:

- despite some inherent advantages of Linux and OS X (Macintosh) working with a Windows host is usually best

- see this post for links to two packages you will likely need

- keep in mind your device is already rooted so you can ignore those steps (and associated headaches)

- identify the 3rd (not 4th) gen HDX device you have: apollo = 8.9", thor = 7"; using the wrong files will 'brick' your device (often with no recovery possible)

- as you adsorb the 'big picture' you see there are three basic steps involved in unlocking the bootloader which enables the installation of custom ROMs

- initially you only need to follow step #2; I strongly recommend that path, especially if you have not dabbled with TWRP and/or flashing custom ROMs before

- after you complete step #2 post back for further guidance; your device will continue to function with FireOS v4 so no lost productivity

- ask questions BEFORE taking action if unclear on required steps or expected outcomes; same if problems/issues arise

Try a factory reset and do not register device w/Amazon during initialization. Kingroot will eventually work (as it has for many others).

Only other option is installing a vulnerable bootloader in 'bulk mode'. This approach is not easy unless you are familiar with working at this level.

Factory reset worked. Its rooted. Now how to install Android?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Go back and review guidance in the original link. At minimum you'll need to install a vulnerable bootloader and custom recovery (TWRP) to support the installation of KitKat based ROMs.

The bootloader must be unlocked for ROMs based on Android 5.x or above.

Plan on spending several hours reading through the material and preparing necessary connections. A PC (Linux/OSX/Windows) is required.

Hi, I don´t consider myself a complete noob, I´ve done a fair amount of modifications on android devices. I have an HDX7" and I´ve read a lot, but I´m really confused. All that I want is being able to run a game that requires google apps... so I guess the question is, is there a quick way to get Gapps working on the stock OS? or do I have to flash another rom? If so, is there a rom thats based on the stock amazon one? I´d prefer to keep it looking like it does now, thanks in advance!
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Google Play Services and store do not play nice with FireOS v4 (not the case with v5). If you have a 3rd gen HDX you will need to root and install a custom ROM to gain full access to Google's framework of services. All custom ROMs retain their Android UX; none 'look' like Amazon's adaptation (ie: FireOS).
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] x_pike:
Thats just too bad, but then, is there a "simple" tutorial for flashing a new rom on the machine? I really love its screen! If not, which of the new Fire would you recommend? Thanks a lot!
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
If you are familiar with terms like 'root', 'adb' and 'twrp' (plus feel comfortable at the Windows command prompt) then I can probably walk you through an install. Please don't underestimate the significant challenges if most or all the above are foreign. It's not the definitions that matter; rather the experiences gained using those tools/techniques.

As for an alternative device none of the contemporary Fire's hold a candle to the HDX line as Amazon has moved decidedly down market; 'premium' tablets (especially displays) are no longer on the menu. You will probably have to spend $250-300 USD to get a non-Amazon device with a 300 ppi or higher panel that matches the HDX lineup.

Broken Touch Screen

Hi everyone.

So my 7 HDX finally died on me.

It fell down and the touchscreen ain't working anymore. For whatever reason it won't connect to my bluetooth controller but bluetooth is on.

I was on the latest stock as far as I know. Didn't do anything with it in the past.

Could anyone help me to:

1. gain access to tablet over pc

---I am a total noob- I installed the adb drivers from xda and the kindle usb driver

(says error when installing amazon driver wasn't installed properly) - if I enter adb shell in CMD nothing happens

2. help me with the commands to disable the touch screen and lockscreen

3. help me with the commands to connect the bluetooth keyboard or a bluetooth mouse

Thank you for any help...would prefer to not throw it away and still use it as a second screen for streaming and chat windows

PS: Can provide discord if needed, as I would like to learn this for the future. Have rooted my phones in the past, but this seems a little more advanced.

I have an HDX 8.9" gen 3. I have a choice to make. Either try to sell it or sell my iPad mini 2, 128gb. I know I can get more $$ and sell the iPad more quickly than the HDX, but I also know that I can use most apps, google and Amazon on the iPad. So, if I root and unlock the HDX, install a custom rom so I can get google apps what does that break, if anything? Do the google apps update OK? Can I still use prime video and download videos for offline viewing? Will casting work via google home?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] pesche80:
I am using the same tablet with LineageOS 14.1 (Android 7.1.2)

Play store is OK. Also Amazon Video Prime, including offline mode.

Camera and Bluetooth are broken with this Android version. But the front camera is working mostly for video chats.

Sometimes Wifi is a little strange and it takes some reconnects to get it working.

I'm not sure with casting and google home though.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Various HDX devices and ROMs have been my daily driver for 2+ years. Agree with [MENTION=3642419]prech[/MENTION]e80's observations. Most things just work but a few become mini projects. Setting up Amazon prime video can be one, along anything that tries to identify the exact device type. Bluetooth is dodgy but workable. Camera's can usually be made functional with a different app. What you gain with the HDX is complete control over the device and better performance. iPad's gets the node for simplicity, and in your case, more onboard storage. That may be the deciding factor (offline video) as neither can utilize offline storage except via WiFi stream or physical tether. For emphasis, HDX devices do not support OTG which most associate with the ability to access content on a flash drive.

So I've successfully installed LineageOS on my HDX 8.9" 3rd gen, but the front camera isn't working too good.

[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] Antonntminh:
Try LP or MM ROM if you want to use front Cam
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
This has less to do with the ROM vs the app used to access the cameras. Try Open Camera or Snap Camera before flashing a different ROM.

Unfortunately I specifically need Skype :(
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Sorry...didn't connect the dots on that important detail. Post if you need more detail on the handful of LP/MM ROMs for this device. I have used most of them some point during their lifecycle (specifically HDX builds). Good luck.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] hoobyjuice:
If you could please suggest the HDX LP/MM ROM that has the longest battery life and/or the fewest bugs, that would be appreciated.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
All of the builds are stable and relatively bug free. That said, each as a small suite of idiosyncrasies that matter little to most and a lot to a few. Almost all are outside the control of the ROM developer/maintainer. Gotta remember this device was discontinued in 2015 and has not seen a kernel update since Android 4.4 (KitKat). Almost all ROMs (for any device) are capable of achieving satisfactory battery life despite popular rumors to the contrary.

In the absence of other criteria I'd lean toward two Marshmallow builds:

- ACIP

- Lineage OS 13.0

Fire Nexus [M4B30X] is a fine alternative but needs a bit more TLC to get fully functional given AOSP roots. If none of these meet your needs then the best option is the tried and true, KitKat based Fire Nexus [KTU84Q] . This build is fully self contained; flash one zip and you are in business. See OP for details.

Note there are several fine Android 7.1 builds for this device but I'm focusing on LP/MM based on a previous poster's recommendation. I am not entirely sure camera problem with Skype is ROM related but don't have a Nougat variant loaded up at present to test.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] hoobyjuice:
I installed LineageOS 13, but found the camera quality no better, so went back to v14.

I'm getting pretty slow wifi - I gather wifi issues are common? Any suggestions on how to speed it up?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
If you mean slow to connect - yes, that's common. You may be able to speed that up by toggling WiFi or Airplane mode. If referring to throughput that has not been an issue, either raw speed or the ability to connect and hold weaker APs.

---------- Post added at 10:40 PM ---------- Previous post was at 10:34 PM ----------

Ability to access/use cameras and image quality are different things. Front camera's on all HDX devices are notoriously bad. The rear camera on 8.9" models is serviceable but no better than those found on entry level phones. Dark images seem to be more prevalent on some devices and not others. As suspected this was not a ROM issue.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] hoobyjuice:
Sorry, this is my silliness. I spoke too soon. I am getting lower quality video on Netflix and Amazon Video than I used to on the unrooted stock rom. I assumed it was because of wifi speed, but I ran the Ookla app speed test and it was fine, as you said.

If you have any ideas how to boost the quality of Netflix and Amazon Video streaming, that would be great! (Strangely, Youtube quality is fine, 1080p looks like it's meant to).

I should have clarified: it was the image quality in Skype I was worried about, which is lower than it was on the stock rom but I can live with it. (Other apps have trouble using the camera but I dont really care about those).
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Most video streaming services attempt to identify device characteristics to determine the stream quality. If that fails they default to the lowest setting. Amazon devices with custom ROMs are somewhat of an anomaly. There are various tweaks to address this issue, some with caveats. See if I can dig up one or two; look for a future edit to this post.

Hi guys,

i have just got a Kindle Fire HDX 7" KFTHWI (Wi-Fi) (Codename Thor) from a friend.

Now it is running Android 4.2.2 with Bootstrap Recovery 3.75 (TWRP v2.7.1.0). When i look up at the forum, it was something very old (like 3 years ago).

I don't think it has an unlocked bootloader.

HDX for remote (repost from wrong forum... oops)

I have a 3rd gen 7" HDX that I want to run Logitech's Harmony remote app on. It is not on Amazon's app store (shocker right?). The only thing I want to do with it is control my Logitech hub for the entertainment system, literally just the one app. I'm on my second Home Control remote and they're not cheap.

Is there a way to get it on there without rooting the device, since it doesn't run FireOS 5.x for the GooglePlay simple route? If not, is it possible to force an upgrade to OS 5.x or root it using a MacBook Pro?

I have read enough to know this device is not easy to mess with for a newb such as myself. I'm not afraid to brick it because we don't use it for anything, but I don't want to waste my time either. Please use small words.... we Apple folks are pretty slow.

Thanks
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Yikes - gonna have to dig deep into my youth vocabulary to find simple words for a (gasp!) Apple aficionado. :)

Unfortunately, you will likely need to go with a custom ROM to gain the desired functionality. At minimum that would require rooting and some technical wizardry to prepare the device to accept a new operating system. All maintenance tasks will be harder being performing from OSX as few have direct experience with this platform for the required operations. Not to mention the challenges of learning a bunch of new terminology that you might never use again. To complicate matters further HDXs are not your typically Android gizmo. You won't find the usual interfaces on this pup starting with an IR blaster (nope), NFC or OTG support (nada, zip). Finally, there's a pretty good chance the poorly regarded Harmony app won't like the platform even with a custom ROM. Good luck getting Logitech to update that for a weird duck like the HDX.

Regarding the other path, a 3rd gen HDX can not be updated to FireOS v5. Period.

Suggestion: Snag a cheapo burner phone from eBay, WalMart or other discount retailer. Don't bother activating/registering it; just connect to WiFi for access to the Google Play Store. Viola - instant host for the clunky Harmony app.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] quaff1:
Thanks Davey. I've already been looking for a cheap tablet on CL, just wanted to see if this was possible. Sounds like it's not worth the trouble for someone of my skill level. FWIW, I don't hate the notorious Harmony app. It works pretty well for me, and is better than the remote for switching from AVR inputs to Smart TV apps and back again. Guess our FIreHD will make a nice doorstop, coaster, or paperweight.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Couple of additional thoughts:

- An inexpensive Fire 7 will likely do the trick. While it likely will not be rootable the Play Store and supporting services can be easily installed under FireOS v5. The best deals come from Amazon Warehouse where 'like new' refurbs can be had for 2/3rds the normal price.

- You could try sideloading the Harmony app from here but it likely won't start on FireOS v4 or will be unusable without accompanying Google Play Services.

If you don't plan to use the HDX toss on CL. Likely be a quick sale.

Just letting you know I've been playing with the build.prop file, as suggested in that post. Haven't had any luck so far. I'll post again if I find a working solution.

USB Audio not working in LineageOS 14.1

I recently had success converting my Amazon Fire OS 4.5.5.2 to LineageOS 14.1 and GAPPS on a Fire HDX 8.9 3rd Gen/2013/Apollo tablet. As I have been using it, I have already found and fixed (thanks to the XDA Forums) the Clock App and the YouTube controls overlay -- they were both simple fixes found by searching the forums for solutions.

I know have noticed that I can not get the USB Audio to work -- I have a DAC and plug it into the USB port using an OTG cable -- works on my Nexus 6 Android 7.1.1 phone. I notice that in "Developer Options" that the "Select USB Configuration" auto switches between modes -- when I plug in a charge it shows as "Charging," when I plug in the audio DAC cable it shows as "Audio Source," when I plug in to my Linux laptop it shows as "MTP." Unfortunately, I have tried manually changing the selection within that menu but still no USB Audio output -- it should output a digital audio stream to my DAC. BTW, the analog audio output via the headphone jack works fine and the tablet speakers work fine. In fact, the Chromecasting works fine (with audio).

Any ideas?

Craig
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Unfortunately, 3rd gen HDX devices do not support any form of OTG including audio output. Also extends to flash storage, navigation aids (external GPS receivers), etc. This is a hardware restriction unrelated to ROM or kernel configuration.

Let's step back. When your device is booted into Lineage (any custom ROM) it will show up under "Portable Devices" in Windows Device Manager. You should see Kindle Fire HDX 7 (or 8.9) in the Device sand Drives group in Windows 10 or a similar category in earlier Windows builds. Clicking on that entry will drill down to "Internal Storage" and the file/folder resident on your device.

Curious what issues/problems you are seeing.

---------- Post added at 09:47 PM ---------- Previous post was at 09:41 PM ----------

Typically a suitable GApps package is flashed (from TWRP) concurrent with the ROM. Open GApps is the go-to solution for most. Recommend going with one of the small packages (mini/micro/nano) on this device due to limited space in the system partition.

Adding a GApps package after flashing the ROM typically leads to problems, especially with CM/Lineage ROMs. Recommend you wipe the system partition then reflash you chosen ROM and GApps package before rebooting.

Wow - I have never seen this on a HDX given the way the device is represented in Device Manager. It's not a bug in the ROM. Some things to try (all may seem remote but options are limited):

- try a different USB cable; can't tell you how many crappy cables have lead to bizarre behaviors when tethered

- try a different USB port; try to use USB2 (if possible) and avoid external hubs if possible

- tether device to a different Windows machine

Help with HDX 8.9 and TWRP

Hi Guys,

Ive been doing a lot of research in trying to install lineageOS 14.1 on my HDX 8.9. However, Im having trouble installing TWRP. Im on 4.5.3, i installed kingroot and rooted it. I think i have an unlocked bootloader (more on that in a bit). I installed flashly and backup my recovery image, but when I flash TWRP (ive tried various versions from the signed 2.8.x to the newest 3.1.x) it hangs on the first kindle logo (all white version) and nothing happens. I have to manually reboot it (with the buttons) to get back into fireos. I looked at some of threads about using the fastboot method but when i do "adb reboot fastboot" it goes into fastboot and say ready(on the tablet screen), but the computer cant see it. "fastboot devices" does nothing. I have played with the drivers uninstalling reinstalling, did it on a couple of windows 7 and ubuntu and the same thing happens. If i do any type of "fastboot" command while in regular mode, the prompt say "waiting for device" but nothing happens. I dont know how else to check if i have an unlock bootloader without fastboot. One more bit of information, if i do "adb shell su" i get the "unallowed user" error. So is there something boneheaded im missing?

Thanks for any help.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] draxie:
LOCKED

Everything you describe points to a locked bootloader.

You need a working fastboot connection to unlock;

so, that's not all that surprising.

Here's an adb command to check (but this won't work

without root):

adb shell su -c 'idme print unlock_code'

Your 'adb shell' might already have root privileges

(check by running 'id'), in which case you can skip

the 'su -c' part.

If your device is unlocked, you get a long base64 string

as a response, otherwise nothing except an error...
