You need to upgrade to 13.3.2.5 first and then to 13.4.5.2. The OTA block must be removed using the same method/tool that was originally used. Keep wifi off or risk receiving an update from Amazon that could brick your Kindle. Uninstall SafeStrap v3 (if applicable). Once at 13.3.2.5 you will need to reroot; suggest towelroot (note wifi must be enabled for a few seconds during the rooting process; be sure to turn it back off). You will have to figure out how to perform various steps by reading through the forums and asking specific questions as you work through each step. There are no videos or detailed tutorials. Keep in mind there is risk involved manually controlling updates including a hard (unrecoverable) brick. A safer method is simply allow your device to update itself which will happen if you remove the OTA block and enable WiFi. Down side it you will likely end up at 13.4.5.4 which can not be directly rooted at present.

Images can be found here.

Or, you can flash an image that does not include the boot loader. There is one on the developer thread, but it is buried. You can use Draxie's tool to make one, but it requires a bit of knowledge to setup correctly.

As of now you could run twrp and unlock your bootloader (you would need to roll back to 13.3.2.3), but if you load 14.5.2, ypou cannot.
[Kindle Fire HDX 7" & 8.9" General] DB126:
Last observation by [MENTION=3038165]lekofraggle[/MENTION] is important. Only a select few HDXs can be unlocked and/or support the installation of twrp. Yours in one of them. If you go that route (it will take some work) you will be rewarded with a device that can run ANY rom adapted for the HDX including Nexus v2/v4, CM11/CM12 and FireOS v3/v4. Recovery options are also more robust should something go wrong. Your options become more limited if you opt to upgrade to 4.5.2 (or anything beyond 3.2.6). Something to think about.

Hmm.. Seems like all Google apps stopped working today. Re-installed the Google play service app and still broken. Looks like another road block.

If interested you can run Nexus 7 (via Safestrap v4) on 4.5.2 which offers a nice interface and FULL access to Google Services and associated apps including the play store. Sure beats the unhappy marriage between Amazon and Google components on an HDX. More info here.
[Kindle Fire HDX 7" & 8.9" General] huludical:
I would love to, but I use the instant video app a lot and don't think it's compatible with that rom :(
[Kindle Fire HDX 7" & 8.9" General] DB126:
Believe it works; did on Nexus 2.0.5. You need to install Amazon phone app (not tablet) which has imbedded support for instant video. I can verify later. On a restricted connection now.
[Kindle Fire HDX 7" & 8.9" General] airplane_guy:
Slightly off topic and it was mentioned earlier but not solved. I downgraded, upgraded, rooted, gapps installed. The peasants are rejoicing. Except, I need to remove the Google account I signed in with and sign in with another.

Data and cache cleared for all Google things, reboot no joy. I understand removing/reinstalling gapps will work, do I reboot between the removal and reinstall? Should I bother with safestrap first before trying?
[Kindle Fire HDX 7" & 8.9" General] DB126:
If you use Google Play and associated apps more than occasionally then Safestrap/Nexus is the way to go. Don't get me wrong - FireOS is great for many people but Amazon and Google don't play well in the same sandbox and likely never will.

If you are running FireOS 4.5.2 installing Safestrap v4 following by Nexus and gaps is a snap. Just follow the instructions in the Safestrap v4 thread. You can even roll back to FireOS if you don't care for Nexus.

Please - follow the instructions and don't install/flash files or versions that don't come from that thread. Every serious problem reported so far is a direct result of user error.
[Kindle Fire HDX 7" & 8.9" General] airplane_guy:
I only need to run about 4 apps. Two of them will be frequent. Everything installed and ran without problems last night, which was great cuz I kinda like the FireOS setup. But, in my excitement to get it working (I already bricked one a long time ago) I signed into the wrong account. FireOS being "on top" there's no way to modify Google account settings. Which wasn't covered in your post. :p

I'll take the long/safe route later. Rollback from 4.5.2, root, gapps, sign into the right account. Safestrap and nexus after and give that a shot. Thanks.
[Kindle Fire HDX 7" & 8.9" General] DB126:
Fair enough. I was not aware of the the inability to change Google accounts on FireOS. Actually, I have never run Google framework/services/apps on FireOS given the headaches, hassles and occasional disruptive behavior. I give you and others a lot of credit for toughing it out.

Keep in mind there are risks associated with rollbacks/upgrades. The most obvious is OTAs which I'm sure you are aware of and manage. But flashes can go bad for a variety of reasons. Kindles lack the ability to recover from such calamities. That is one big advantage running Nexus (or even FireOS) under Safestrap. Flashes take place within the Safestrap envelope; if things go bad you simply delete/recreate the slot. And Safestrap itself is installed, not flashed. It's not quite as safe as a classic virtual machine but much better than the alternative on a locked Kindle with a crippled stock recovery.
[Kindle Fire HDX 7" & 8.9" General] windwaker87:
Just tried to install GAPPS with links provided. Did not read the whole thread to the end (because it's 20 pages). It appears I have used the wrong PrebuiltGmsCore.apk (from 032/priv-app) and it bricked my KFHDX Apollo. Now it does not boot. I can still use the power+volume_up to go to reset/reboot menu. Can I do anything to unbrick this or is it lost completely?
[Kindle Fire HDX 7" & 8.9" General] DB126:
Little (essentially nothing) can be done if your device fails to boot or hangs at the grey Kindle logo. Amazon crippled the stock recovery and fastboot environments. Neither can be replaced with a locked boot loader. The normal suite of low level recovery tricks simply do not work on a HDX. Sorry for the bad news.
[Kindle Fire HDX 7" & 8.9" General] windwaker87:
Well it's not completely stuck at the grey Kindle logo. The logo shows for a few seconds and then switches to a black screen and does nothing else. Tried connecting with USB but nothing happens. Could this be solved at a repair service (paid service included)?
[Kindle Fire HDX 7" & 8.9" General] DB126:
Sometimes that can be a positive sign; suggests the OS *may* be starting but hasn't properly engaged video components. Key to further diagnostics/resolution is adb access. Had you taken steps to enable adb when your tablet was working (via FireOS setting)?

If a tethered connection cannot be established I don't believe a paid service can help due to the crippled interface on HDX devices. Common recovery techniques such as 'factory cables' simply don't work. Obviously a discussion with potential service providers is key to setting expectations and payment parameters.

Question

Guys i'm having an issue with google play store, seems working fine but it say my device isn't compatible with a few applications like tap titans game, is there ant way to bypass this ? or fake the device id to the store ? thank's :D
[Kindle Fire HDX 7" & 8.9" General] DB126:
You really want to go with a different ROM (eg: Safestrap variants of Nexus v4 or CM11). Google Play Services and several related apps don't play nice on FireOS. Sure, you can get it to work...kinda, with compromises, until the next time it breaks. Unless you have a passion for FireOS go with one of the roms listed above. You won't be sorry.
[Kindle Fire HDX 7" & 8.9" General] redpepi:
I see well I mainly did it like this because I Just have 16gb is there any good guide maximazing free storage with safestrap around? Thanks
[Kindle Fire HDX 7" & 8.9" General] DB126:
A custom ROM overwrites FireOS in Safestrap v4. You can backup your existing install for later restoration if desired. As such space utilization (both ram and permanent storage) is equal to a bit better than FireOS which comes with a lot of bloat pre-installed.

It's possible to create and use multiple slots in Safestrap v4 but it works best when only the stock slot is used.
[Kindle Fire HDX 7" & 8.9" General] rb11701:
First time poster here. So, I was able to get everything done to root and install gapps based off the OP. I was adding some apps for my son that were not available on the Amazon Appstore. I installed the Youtube for kids app and when I tried to run it it said I needed a newer version of the play store or play services. I did that and everything seemed ok. Next thing I know, the play store just loads with a white screen.

Any ideas on this? Was I not supposed to update play services? What can I do now?

I used Kingroot to root the HDX.

Thanks in advance.
[Kindle Fire HDX 7" & 8.9" General] DB126:
If you are using Safestrap v4 you may have to wipe cache/dalvik from within SS recovery and possible reinstall gapps. If you installed gapps under FireOS then all bets are off. Amazon and Google frameworks were never designed to work together on the same device. With sufficient effort one can get Google Play and associated apps to work under FireOS, sometimes, usually with compromises and further battles with every upgrade. The only reliable way to get Google services working on an HDX is to install a different rom. Which options are available and the effort involved are dependent on the version of FireOS you are currently running. If 4.5.2 you can install Safestrap v4 which (at present) supports Nexus v4 and cm11.
[Kindle Fire HDX 7" & 8.9" General] mcasara:
hello, as said i disabled OTA and downloaded gapps. i copied all files but there are several PrebuiltGMSCore.apk files in optional folder. which one should i install?
[Kindle Fire HDX 7" & 8.9" General] fadenfisch95:
I followed the instructions in the first post by the letter. Unfortunately, it rendered my kindle unusable.

It boots up unto the second Kindle Fire screen and gets stuck on it forever. I tried hard resetting, but that didn't change a thing. I do realize there might be very little I can try at this point, besides sending it back to amazon, however I'd love to hear if there are some suggestions for fixing this myself?

ADB was activated before this happened.
[Kindle Fire HDX 7" & 8.9" General] EncryptedCurse:
Can you actually get it to show up in adb devices?
[Kindle Fire HDX 7" & 8.9" General] fadenfisch95:
Yes. I tried a command to uninstall Play Services, which led to the console getting stuck.
[Kindle Fire HDX 7" & 8.9" General] alberto1414:
Can someone post the old files?? I read all the post and seems to be the gapp file the problem. can someone shared the old apks.

we have a lot of folder inside them a lot of the same PrebuiltGmsCore.apk.

any help? or I dont have to copy the optional at all?
[Kindle Fire HDX 7" & 8.9" General] DB126:
Can't help with your specific request but will offer some (potentially unwelcome) guidance: do NOT follow this method (or any other) to install Google Services under FireOS. The two do not play nice together; you can get it to work, sometimes, with various compromises and the promise of further incompatibilities when any component is updated. Freezing the environment is a short term solution at best as Google is becoming more aggressive with app/framework dependencies. Safestrap v4 and a different rom (Nexus v4 or CM11) is the best solution IMO as either will transform your FrankenKindle into a fully functional android device.
[Kindle Fire HDX 7" & 8.9" General] Giraffackle:
Hopefully someone can help out here. I did this entire guide, and the playstore launched, I logged in, and it worked. I closed it and opened it again and I just get a white screen, the store doesn't actually load. Does anyone know what's wrong?

Thanks :D
[Kindle Fire HDX 7" & 8.9" General] DB126:
See previous post. While someone may be able to solve your current issue it will only reoccur at some future time. Give serious consideration to Safestrap ... and don't do a factory reset.

[Kindle Fire HDX 7" & 8.9" General] DB126:
Second [MENTION=6815340]Cl4ncy[/MENTION]'s remark on not cross posting. As you bricked your last HDX doing something foolish I suggest you slow down, understand your options, procedures to accomplish those goals and things to avoid. Also recommend that you NOT install gapps on FireOS. Use Safestrap v4 and a different ROM (Nexus v4 or CM11). The procedures listed in this thread will only lead to trouble unless you are experienced and willing to work through the issues without trashing your device. Good luck.

[Kindle Fire HDX 7" & 8.9" General] Cl4ncy:
You should/must have Fire OS in the stock slot for this!

Remove Safestrap (delete secondary slots, if you created any), install TWRP, flash the 3.2.3.2 bootloader update via TWRP, unlock the bootloader (info here and here, probably requires these drivers if you use Windows, and you should install Minimal ADB and Fastboot), then use ROM of your choice, i.e. either Nexus v4, CM11, CM12 or SlimLP. Note that you can NOT use any of those with Safestrap v3.7x!

Any questions ask first, i.e. before you brick your HDX! ;)
[Kindle Fire HDX 7" & 8.9" General] Todobien:
Installation TWRP required

- Ensure you are running stock firmware .3.2.3.2 (I have not, you told me before "install TWRP")

- Obtain Root ( is already rooted)

- Copy the recovery image to the root of your sdcard (ok)

- Flash the recovery image by issuing the following commands: (Where? with what program? )
[Kindle Fire HDX 7" & 8.9" General] EncryptedCurse:
You can use Flashify instead.
[Kindle Fire HDX 7" & 8.9" General] Todobien:
ok, I installed TWRP and flashed 3.2.3.2 bootloader update with TWRP, now how to unlock the bootloader?
[Kindle Fire HDX 7" & 8.9" General] Cl4ncy:
Did you install minimal ADB & Fastboot? You also need the software mentioned in the links above (i.e. Python, GMPY2, and the Python script), then you have to open a couple of command prompts, as I mentioned in the second link regarding unlocking above.

If you have problems with Python just execute the adb commands to get your ID and serial, PM me them, I'll create the unlock file for you then. Actual unlocking is a task you'll have to do yourself though. ;)
[Kindle Fire HDX 7" & 8.9" General] Todobien:
Yes, minimal ADB & Fastboot installed:

"Microsoft Windows [Versione 10.0.10240]

C:\Program Files (x86)\Minimal ADB and Fastboot>"

PYTON 2.7 and 3.5 + official Android SDK(full) in download.

I sent you my serial, but i don't find ID (need to open adb in TWRP?)

[Kindle Fire HDX 7" & 8.9" General] Cl4ncy:
Replied to your PM.

I see you use Windows 10 x64? That could be a problem regarding the ADB driver installation in order to get your HDX recognized by fastboot. Do you have access to a Windows 7 PC?

[Kindle Fire HDX 7" & 8.9" General] Todobien:

[Kindle Fire HDX 7" & 8.9" General] Cl4ncy:
What do you mean 'where'? In the adb shell/command prompt. Just like you did with the ID, just enter the adb shell command, and then the cat /sys/block/mmcblk0/device/serial command, and ensure the entire command is in lower case letters.
[Kindle Fire HDX 7" & 8.9" General] Todobien:

installed TWRP

flashed the 3.2.3.2 bootloader

unlocked the bootloader (how can I check it?)

Can i install "HDX_Nexus_ROM_Apollo-v4.0.5"?

Which is the best?

Whenever can i install a rom only on the first slot?
[Kindle Fire HDX 7" & 8.9" General] Cl4ncy:
Did it say unlock code correct, like in the attachment here? Then it's unlocked.

Yes, you can use this Nexus ROM, read the installation notes and requirements carefully, and be sure to create a backup in TWRP first and move it to your PC before you flash any custom ROM! I'm using CM12, but you can check out which you prefer. Just pay attention to the Installation notes, and note that factory reset means the standard wipe only, i.e. usually you shouldn't open the advanced wipe menu.

Unfortunately TWRP on the HDX has no slots like Safestrap, so you can not use different ROMs so easy.
[Kindle Fire HDX 7" & 8.9" General] Todobien:
i remember only green written
[Kindle Fire HDX 7" & 8.9" General] Cl4ncy:
Well, the green "Unlock code is correct" is on the HDX display of course. ;) Otherwise it would've been a red "FAIL: unlock code is NOT correct!" message.

As [MENTION=5488402]Davey126[/MENTION] mentioned here you can also try to open a fastboot prompt (i.e. DOS box, then change dir to your adb directory):

fastboot -i 0x1949 oem idme

You will only get a response if unlocked.

If you do recover your device (there are methods; many documented within this thread) give serious consideration to installing Safestrap v4 and either Nexus v4 or cm11. Both roms offer full access to the Play Store without the inevitable hassle of trying to get Amazon and Google frameworks to coexist.

Don't recommend installing GAaps on FireOS v4; endless headaches. Might consider a custom ROM (cm11 or Nexus) which installs easily and offers full access to the Play Store. Replaces FireOS.

Yep. Procedure is dated and unreliable. You'llneed to sideload an alternate launcher to (maybe) get out of the language select pit. You'll find guidance buried in various threads. Do a search.

FireOS v4 and GAaps don't play nice together which is what the post immediately prior to yours said. Yet people keep trying...and failing.
