Agreed. Not going to happen as OP is now 369 days old and counting ...

Replacing core files (again) would be equally dangerous. Assume you are on FireOS 4.5.5.1, rooted with Kingroot and then ran into trouble. Best path imo is to completely replace FireOS (via Safestrap v4) which will clean out your personal data if done properly (there are ways to retain personal data but the update may not take). This is a modestly involved task that is not risk-free. Post back if you want to pursue or hang tight to see if someone else responds with a better idea.

The Safestrap route also offers the opportunity to run a custom rom instead of FireOS. Far better option if looking for Play Store access. Basically turns your Kindle into a very nice "android" device mimicking a Nexus 7.
[Kindle Fire HDX 7" & 8.9" General] Zavxda:
You assume correct. I was able to log on to Google and link my sec coc acct and can access es explorer so I won't loose anything! lol

Thanks for your help I'll consider custom ROM but a bit nervous

If I was to add the missing system files it wouldn't hurt to try right? I can always try and then when it doesn't work(most likely) I can go the custom ROM route... Thoughts???
[Kindle Fire HDX 7" & 8.9" General] DB126:
- first need someone to cough up proper version of the needed files (or you'll need to do the homework to extract from a stock image file)

- if something goes wrong the device may not restart potentially leaving you with a soft-brick; factory reset will do nothing to help as it only deletes user data

- normal recovery techniques do not work on many Amazon devices and are notably limited on HDX models
[Kindle Fire HDX 7" & 8.9" General] Zavxda:
Right technically the files I added replaced existing files that had the same name the only way to know what files I need is to compare the files I used to a unzipped "stock" ROM... And HOPE that they are named the same... I am pretty new to all this so bare with me, because I rooted the device does that mean the boot loader is unlocked too???
[Kindle Fire HDX 7" & 8.9" General] DB126:
- rooting and bootloader unlock are different things; unfortunately, you can not unlock the bootloader on your device (would fix the problem)

- agree file names should be the same. However, few in these forums run FireOS. Once rooted folks tend to migrate to a custom rom pretty quickly

- none of my devices have FireOS installed; never ran any version above 3.2.6
[Kindle Fire HDX 7" & 8.9" General] Zavxda:
That's what I thought... Silly Amazon... thanks so much for your help! Ill let you know what I decide to do.
[Kindle Fire HDX 7" & 8.9" General] damianlph:
Step 2-2, Copying everything is too manual, too many folders and files, is there another way to do it more auto?

Thank you!
[Kindle Fire HDX 7" & 8.9" General] Zavxda:
So i have been dealing with this Kindle for a couple months... with no home button and the only way to access the apps is through the pullout side bar and ES file explorer/opening the app from the play store!

Today I finally went the savestrap route and flashed a nexus rom. Done in a matter of min and without any problems! I cant believe how nice it is to have a fully functioning tablet again that is not tethered(chained!!) to amazon!!!
[Kindle Fire HDX 7" & 8.9" General] pistonrod:
For those who stupidly Factory Reset the device and lost Root (like me) you will have to install and run Kingroot in adb first, then run these commands.

1. Skip through Google Setup and setup your Wifi connection.

2. Enable ADB in Developer Options

3. Install and run KingRoot apk from ADB

a. Download from http://www.kingroot.net/wap/download; should be RushRoot-CafeUser-release-nolog-sdk-lc5F16405FCD186348-b220-svn373799-201609072045_signed_krsigned.apk

b. Move to your adb directory and rename to RushRoot.apk

c. Run these commands from command prompt

adb install -r RushRoot.apk

adb shell monkey -p com.cafeteam.installer 1

This should startup the KingRoot app and allow you to root your Kindle. Mine failed on the first try, so I rebooted and tried again with success.

You can now run these commands to disable the setup:

adb shell "su -c 'mount -o rw,remount /system'"

adb shell "su -c 'mv /system/priv-app/SetupWizard.apk /system/priv-app/SetupWizard.apk.old'"

adb shell "su -c 'mount -o ro,remount /system'"
[Kindle Fire HDX 7" & 8.9" General] DB126:
Assume you are running Kingroot via adb to avoid OTA update to 4.5.5.2? If so not really a concern as partial FireOS update downloads are discarded on reboot and Kingroot reboots frequently during root attempts.
[Kindle Fire HDX 7" & 8.9" General] Archangel1183:
I know this thread is old, but I was finally able to root my HDX 7 4.5.5.2 and want to install Google play store and all the necessary apps. I've read that Safestrap loads over the FireOS and the first OS is still using up memory in the background. I don't know if the article meant RAM memory or internal space memory. Anyone know which one it is? I only have 16gb's on my HDX.
[Kindle Fire HDX 7" & 8.9" General] DB126:
Safestrap is obsolete. Plan on unlocking the bootloader and installing CM, Fire Nexus or another custom ROM if you want to use Google Play Store/Services/apps on this device. FireOS v4 and GAaps do not play nice together.

[Kindle Fire HDX 7" & 8.9" General] rohith.gm:
Tried this method yesterday. Got the device (Kindle Fire HDX 7 ) rooted thanks to kingroot. After that i tried to copy each othe contents in the folders to the respective system folders. But while doing so, i kind of get into an unexpected low storage :crying: and i had to stop the process. So the result was that, i modified the system partially :crying::crying: . So i had no other option but to quit and restart the kindle. Sad to say that it is kind of in a bootloop right now showing "Kindle fire" (fire in orange). What do you guys suggest i do next ? Any queries will do me a lot of favour. i am thinking of buying a fastboot cable if it all helps. Any suggestions anyone ???
[Kindle Fire HDX 7" & 8.9" General] Potato_of_Doom:
Question 1: Did you unlock the bootloader?

Question 2: Why are you trying such an old method from an abandoned thread?

Question 3: Did you read the complete thread?

Question 4: Why did you reboot your HDX?

If you've enabled ADB before you could try connecting to the bootlooping hdx (this only works sometimes) and restore some systemfiles (which shouldn't be the case). If this doesn't work you are probably out of luck
[Kindle Fire HDX 7" & 8.9" General] DB126:
With ADB (and previously granted permissions) it may be possible to derive sufficient information to unlock the bootloader. Otherwise, not much can be done. Fastboot cables are useless on this device.
[Kindle Fire HDX 7" & 8.9" General] EncryptedCurse:
Except you can't install TWRP with FireOS 4.
[Kindle Fire HDX 7" & 8.9" General] kulturschock:
How do you get root on fire OS4 except you flashed a modfied zip with twrp? I think, there's still no possibility. Perhaps I'm wrong...
[Kindle Fire HDX 7" & 8.9" General] EncryptedCurse:
The exploit which is utilized in flashing TWRP or unlocking the bootloader has been patched since x.3.2.4.

You can root FireOS 4 with p1gl3t's app.

Followed the instructions to the letter and worked great. Thanks for the guide!!
[Kindle Fire HDX 7" & 8.9" General] gog08:
Copied all the files, except the mentioned ones. After reboot, it shows default Android welcome screen and asks to select language, after that it takes me to the WiFi settings, after i connect to my WiFi it does nothing. And the most important i don't have the home button, only the back button. I did a factory reset, and now even the back button disappeared))), and now I'm stuck in the settings menu. If i reboot again, it shows the same welcome screen. Any opinions about this?
[Kindle Fire HDX 7" & 8.9" General] oOFrAnzOo:
Got an Awnser:

connect the device with adb, then start console:

(I used windows)

1. adb shell

2. su

3. cd /system/priv-app (the location you moved the SetupWizard.apk)

4. rm SetupWizard.apk

5. reboot

The SetupWizard block's the Device. So you have to remove it.

Should you have problems with downloading Apps via Google Play:

Go to Wi-Fi setting and change the DNS1 to 8.8.8.8
[Kindle Fire HDX 7" & 8.9" General] gog08:
I did as you wrote, but on the step 4 i get this:

rm failed for SetupWizard.apk, Read-only file system

how to root?

Sorry, but I still do not understand how to root my Apollo on 14.5.2. Currently it is still running on 14.3.2.3.2 and safestrap.

I would really appreciate if someone could post a tutorial on how to upgrade and root. Cheers.
[Kindle Fire HDX 7" & 8.9" General] ONYXis:
you need

mount -o rw,remount /system

after su
[Kindle Fire HDX 7" & 8.9" General] gog08:
Big thanks to oOFrAnzOo and ONYXis, you saved me, after deleting setupwizard.apk and reboot, still stuck at the welcome screen but now of Amazon, made once again a factory reset, and the tablet is alive, with root and Google Play. Once again thanks.
[Kindle Fire HDX 7" & 8.9" General] ONYXis:
are you sure? su probably deleted after hard reset.
[Kindle Fire HDX 7" & 8.9" General] gog08:
Yes, I don't know how, all other apps I had, are gone, but SuperSU is present.
[Kindle Fire HDX 7" & 8.9" General] ONYXis:
supersu doesn't mean root, this is just application for manage. does supesu start normally?
[Kindle Fire HDX 7" & 8.9" General] gog08:
Yes it starts normally, I guess. I also installed Es file explorer and turned on root explorer, super su popped up and asked to grant access, and i did.

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

For wallpapers - need to patch framework-res.apk or use launcher with own wallpaper mechanism (go launcher for example)
[Kindle Fire HDX 7" & 8.9" General] lekofraggle:
You can also try to find an app which sets wallpaper along with either the kindle fire wallpaper fix, kindle free, or hdxposed. I am sorry, I do not remember which worked.

Well, I have successfully rooted my HDX Apollo 4.5.2. However, while installing GAPPS I have just done what you mentioned in your post - and deleted Setupwizard.apk - which leaves me with a half bricked device: after rebooting the launcher has gone. I can only enter settings but I cannot start any apps. A factory reset shows noch improvement: I can choose a language and then remain stuck in the settings menu - no launcher visible. Could you please let me know how you managed to fix this?

Would somebody be so kind and upload the setupwizard.apk for me so I can push the app via adb back to where it belongs - and possibly help me save my kindle fire?

Did you use the gapps package from my description? (Otherwise its possible that you have a version compiled for the wrong architecture)

[MENTION=261972]tuanda82[/MENTION]

Nope(as you can see on my screenshots) - maybe you installed the wrong xposed module or killed the build.prop:p

I couldnt find this line in my build prop "Check your build.prop (system/build.prop) and search for "ro.sf.lcd_density=YOUR DPI". From there, match up your DPI to the appropriate GApps package. See below for comparison"

Edit: I think I have downloaded the ones for Android 5, I will download for 4.4 and do it all again :)

ok I have now downgraded and updated to 4.5.2, rooted and disabled OTA updates.

installed the PrebuiltGMSCore.apk and I now have a google play services app on the device but It doesnt do anything when I try to run it.

I must have missed something ......
[Kindle Fire HDX 7" & 8.9" General] fabische:
Thanks, Potato_of_Doom for uploading the APK. It still did'nt improve much, I was still stuck in the settings menu without a launcher or home button. Eventually, I have reactivated the OTA Updates and let the whole machine update to 4.5.3. Well, root is gone, of course, however now I have at least a usuable device.

One of the problems I encountered using the GAPPS method described here was that when I tried to copy the files into system / priv-app I got loads of "out of memory, can't write" errors. This has certainly muddeled up things.

This is not to say that I am giving up and have an unrooted Kindle fire.

Does anybody know if there is a way to downgrade from 4.5.3 to 4.5.2 or any other rootable version of fire os?

cheers!

Ok I now have the setup screen, but, I select the language English UK, then I press the next button which takes me to the wifi connect page, I connect to my wifi and press the back button.

I am now back on the language select page which I press the next button, it then turns off the wifi, I then reconnect and it justs cycles like this .....

I installed gapps-kk-20150308-minimal-edition-gps030-universaldpi-signed, I then overwitten this with gapps-kk-20150308-minimal-edition-gps036-320dpi-signed to get the setup to work.

with the universal I copied folders over, with the 320dpi I copied the files into their corresponding folders.

going to try a reset of the device and try 320dpi files copied over into each folder, unless someone and guide me other wise :)

[Kindle Fire HDX 7" & 8.9" General] neils31:
Thanks for that, but it doesnt seem to be picking up the update, would it be because I have already disable the OTA update?
[Kindle Fire HDX 7" & 8.9" General] Potato_of_Doom:
Yes you obviously have to rename DeviceSoftwareOTA.apk back to its original filename

When reenabling OTA your kindle will ask you to do a normal ota, so disable wifi to prevent your kindle from eventually bricking itself
[Kindle Fire HDX 7" & 8.9" General] neils31:
yeah thats waht I thought, but How do I get to the file to rename it?

Before pushing it back try

thanks but I got this

C:\adb>mount -o rw,remount /system

'mount' is not recognized as an internal or external command,

operable program or batch file.

C:\adb>
[Kindle Fire HDX 7" & 8.9" General] jeryll:
Ok you need to do this:

adb shell
su
mount -o rw,remount /system

And then use push command
[Kindle Fire HDX 7" & 8.9" General] neils31:
This is what I have tried :-

C:\adb>adb shell

shell@thor:/ $ su

su

root@thor:/ # mount -o rw,remount /system

mount -o rw,remount /system

root@thor:/ # push DeviceSoftwareOTA.apk /system/priv-app

push DeviceSoftwareOTA.apk /system/priv-app

tmp-mksh: push: not found

127|root@thor:/ #

as you can tell I am not too familiar with this shell / adb stuff.

would I need to come out of shell before using push?
[Kindle Fire HDX 7" & 8.9" General] EncryptedCurse:
Yes. The command needs to be prefixed with adb as well.
[Kindle Fire HDX 7" & 8.9" General] neils31:
woohoo

finally got it :)

root@thor:/system/priv-app # mv DeviceSoftwareOTAOLD.apk.OLD DeviceSoftwareOTA.apk

did the trick

thanks for all your help everyone.

Now I have to start again but where did I go wrong in the first place.......
[Kindle Fire HDX 7" & 8.9" General] jeryll:
Im replying you in work while moving between different location, so my replies are a little hectic and not complete, forget about push command, use

adb shell
su
mount -o rw,remount /system
mv /system/priv-app/filename.old /system/priv-app/filename.new

With this you can rename file right in system directory without pulling/pushing anything

Edit:I see you done it right before this post ...
[Kindle Fire HDX 7" & 8.9" General] neils31:
Ok I went through everything again and followed it by the letter this time ....... honest

I first tried this package gapps-kk-20150308-minimal-edition-gps030-universaldpi-signed, and nothing happened

I then downgraded and upgraded etc all again

I then tried this package gapps-kk-20150308-minimal-edition-gps036-320dpi-signed, and again nothing happened although I can see google play services i the apps.

Which version will work? or do I have to manually install the apk's ?

Version number -030 = Universal DPI & armeabi-v7a CPU tried

Version number -032 = 160 DPI & armeabi-v7a CPU

Version number -034 = 240 DPI & armeabi-v7a CPU

Version number -036 = 320 DPI & armeabi-v7a CPU tried

Version number -038 = 480 DPI & armeabi-v7a CPU

If i follow the described steps to enable the gapps [Thor], i've recognized, that the essential playstore-apk is missing.

So i've downloaded and installed the apk and got one more step forward. The playstore opens but says, that theres no connection.

So i've installed the xposed framework and the hdxposed module, enabled it in the framework and after rebooting the playstore works and i was good to go.

So (in my case) some additional steps were needed:

- follow the steps as described in the start post

- download the google playstore apk here and install it.

- Install the xposed installer

- Install the hdxposed.apk

- start the xposed installer and download/install the latest framework

- enable the hdxposed module

- reboot

- start the playstore

If you experimented with different packages or anything else before, i recommend to backup your personal data, do a factory reset and start from scratch!

This was the way, it works for me on HDX 7, FOS 4.5.2, rooted.

As always do this at your own risk! I'm not responsible for any unwanted sideeffects, data loss or bricking your device!
