Makes you wonder what was actually "patched/updated" in that version..
[Kindle Fire HDX 7" & 8.9" General] fireleisure:
Downgrade by renaming Update-file

Hi there,

I once had a WD TV live Media-Player.

It was downgraded this way:

-Download an Old Firmware

-rename it to a newer Version and

-put it in the directory where the new firmware should be placed.

It's trivial, but i Asked me if anybody tried out this way for the Fire HDX:

Thats what I Did :

KF HDX 3rd Gen. , Fire OS 4.5.1:

- downloaded update-kindle-13.3.2.4_user_324002120.bin

- renamed it to : update-kindle-13.4.5.2_user_452004120.bin

- Connected to PC an put the file in the Internal storage folder as described for Manual Update.

After this i looked in the Device Settings -> System Update.

An Wow:

My Kindle told me there is a Update 13.3.2.4_user_324002120 ready for Installation.

As i dont have too less experience with rooting Kindles and it was even a 64 GB Version,

i stopped at this point, in order not to brick the device.

Maybe someone could discuss this possibility to downgrade?
[Kindle Fire HDX 7" & 8.9" General] neeeee:
If you do that, the kindle will tell you that you have a newer version than that provided. You can circumvent this by changing the versionnumber inside the .bin file. However then you get a uable to verify message, because the files are signed. I don't think we could get around that.

I also discovered that in the current OTA file (4.5.2) there is a shell script called "provision_anti_rollback.sh". It seemes to set some kind of fuse bit. Could it be that they turned off rollbacks with that?

Could someone who gets a downgrade from amazon look with something like wireshark what they send to your device? Maybe we can emulate the roll back command.
[Kindle Fire HDX 7" & 8.9" General] tl3:
Johnny-come-latelies to the KFHDX scene should read through some of the HDX forums here at XDA first, and try to catch up with the current developments... ;)

Woow! Just now i look at my device and it got the 13.3.2.7 update! ....So yes it is possible to roll back from the latest 4.5.2.........I guess it's rooting time now:)

I just had mine successfully rolled-back after about a 15 minute call with technical support. I was on 4.1.1. This is legit.
[Kindle Fire HDX 7" & 8.9" General] xiloraptor:
Yes realy.. Then i followed xda's threats to complete the root process+safestrap...and install the latest nexus rom(thor-nexus-rom-v2.0.2). I must say my kindle fire HDX is amazing now! everythings working realy smooth.. I wanna thank all the dev's for making this possible..!!:good: I added some screenshots you asked for..
[Kindle Fire HDX 7" & 8.9" General] slugger09:
I'm on 4.5.2, called them twice about a roll back but all will do is replace it.
[Kindle Fire HDX 7" & 8.9" General] d0kth0r:
Wow, cool ! I've just been successfully downgraded to 3.2.7 too (from 4.5.1. though) and I'm wondering if you further downgraded to 3.2.4 to get root/Safestrap/Nexus Rom running or if that's possible with 3.2.7 too.... because that would be great news too :). And if you downgraded to 3.2.4 first: how did you do it ?

Thanks!
[Kindle Fire HDX 7" & 8.9" General] slugger09:
Many thanks for your help, I can confirm this works. I was on 4.5.2 and I am now in the process of getting downgraded. They said they would send all via email, I wonder how long the process takes?
[Kindle Fire HDX 7" & 8.9" General] Ali Ejea Mc:
hehehe Glad to hear that... :)
[Kindle Fire HDX 7" & 8.9" General] Ali Ejea Mc:
Hey guys... My KFHDX is also successfully rolled back to 13.3.2.7 from 4.5.2

Can I ask how long it took them to do it?

Fook they're in no panic are they? They told me 2-3 days, I guess they bull$hit a bit.

You can follow this tutorial to root, install safestrap recovery and playstore on KFHDX 7" if you get it rolled back to Fire OS 3

[Kindle Fire HDX 7" & 8.9" General] xiloraptor:
Stay on 3.2.7 and then root with https://towelroot.com/ after that you install Chainfire superSU v2.40 for superuser privilege.

Install Safestrap Thor 3.75-os3.2.4-B02 and backup your stock rom..

Creat rom slot and flash the rom + gapps.
[Kindle Fire HDX 7" & 8.9" General] AmazonLeaker:
They have removed the tool from customer service representatives to downgrade the developers of OS locked it to themselves now so guys better reach out on calls for direct work and if possible escalation as this is totally unfair now!

They are not giving freedom to choose the operating system atleast if not that an option to enable / disable OTA or cancell OTA install should be given rather than forcefully updating
[Kindle Fire HDX 7" & 8.9" General] slugger09:
Just been downgraded to 3.2.7 now don't know where to begin to get the Nexus rom on this
[Kindle Fire HDX 7" & 8.9" General] Ali Ejea Mc:
Well, do you wanna keep the stock ROM and install HDX Nexus ROM on secondary ROM slot or you just wanna install the HDX Nexus ROM?

Well i don't use anything Amazon related so don't need kindle stock. I've managed to root it, installed safestrap but that's as far as I've got.
[Kindle Fire HDX 7" & 8.9" General] d0kth0r:
I can confirm this works! So no need to downgrade to 3.24 to get the Nexus Rom to work, it works with 3.27 (and I guess with .25 and .26 as well). Thanks for your help!

Am I boned?

Well I got pushed into the 4.5.2 update from 4.2.0 on my Saturn...

Am I boned? Or are all Saturns boned to begin with. I am a heavy Amazon user but I want my damn Google Apps, mostly the only reason I want to root is so I can get Google integration working seamlessly.

*sigh Amazon* just give in and let Google put Gapps out for Kindle.
[Kindle Fire HDX 7" & 8.9" General] angel13th:
I was entered stock rom slot to try something yesterday and got updated. :( And I found this post, so I enter a chat with amazon staff and got it downgraded to 13.3.2.7

All I have to do is said that my app is unusable after update and they just like fine we'll do a rollback for you.
[Kindle Fire HDX 7" & 8.9" General] libelah:
I succeded in initiating a rollback to Fire OS 3 through Amazon Customer Service (German) too. After some Mails and Chats finally they promised me to initiate Downgrade after escalating the case to a supervisor. Lets see how long it will take...

They told me it will still be possible to upgrade to newer FIre OS later on (but only version by version), but I won't receive automatic updates anymore - which is quite perfect imho.
[Kindle Fire HDX 7" & 8.9" General] uramisten:
wow.. I just called the US help line and a very helpful woman passed me to another helpful lady in the OS team who did a rollback for me online - kept me on the phone until the process was complete. Easy as pie. Luckily I was using magicjack, so call charges were nil.. :) Since then.. all is happy and I love my rooted kindle :)
[Kindle Fire HDX 7" & 8.9" General] DivinityCycle:
I'm in the same boat. I grabbed a Saturn while they were on sale because I drooled over the specs. The Saturn hardware is so nice, but I hate the Kindle OS :(

It seems like the general consensus around the boards is that Saturn is just a no-go right out of the box due to the updated software. Remember, Amazon gives you 30 days to return stuff! I'm considering it...
[Kindle Fire HDX 7" & 8.9" General] Strapples:
Its all good...

Well I am KEEPING my saturn.

Fire OS can be circumnavigated with a different launcher, just Sideload it.

Google Apps except Play Store all work with simple ADB sideloading and kicking one command through to make Kindle Fire OS understand Youtube permissions. Google Play Services even functions

Getting apps from GAPPS store to Fire OS is easy. Buy an app that you KNOW IS TABLET COMPATIBLE (if not it will look stretched!) use an APK extractor on your phone to get the APK to the Kindle... Sideload it, when the app checks for a Google License it will ue Google Play Services (working) to check with google servers instead of going through play store.apk (not working)

This is a great stop gap until a full root is done. Honestly, I do not see the need for a full root unless I am doing custom ROMS (I never do on any of my devices, I DO mod my stock ROM a bit)

only thing I miss is NO QUIET TIME UP THERE... DAMN YOU FIREFLY! Though firefly is oh so useful when I am at the store and just want to tap a button and know exactly how much cheaper the product I am shopping for is and tap a button another to order it from my yummy prime!

The decision is yours to keep or get rid of your Saturn, but the hardware you hold in your hands you will not be able to beat on a pure android or iOS device without spending easily double what you spent on your Saturn.
[Kindle Fire HDX 7" & 8.9" General] DivinityCycle:
I didn't even know you could do that without root :) That's awesome! I can easily kick the APKs I need over from one of my other devices.

For some reason, I thought that the Google Play Services required the market or some other thing that you need root to install. Do you have a link for the Play Services you used? I'd imagine it would just whatever the latest version is for KitKat right?

-EDIT-

I have now spent a couple of hours messing around with this crap, trying to get my Google applications to run. I am heavily reliant on Google's infrastructure, so getting stuff like Google Play Books working is very important to me. It seems like this may be do-able by installing some combination of the Google Account Manager, Google Play Services, and Google Services Framework. However, I haven't found anything that actually works :( This is on the Saturn AKA 4th Generation Kindle Fire HDX 8.9" running Fire OS 4.5.2. Anyone have any suggestions, or is it simply impossible to use a Google account with this OS without root?

I'd like to know also though I have the Thor. The old guides and files no longer work as I get FC's all the time.
[Kindle Fire HDX 7" & 8.9" General] jimyv:
lol

a lot of people including myself had such arguments exactly a year ago on the HDX model. I currently have three of them collecting dust. As compared to my older tablet which I have picked up and gotten back to.
[Kindle Fire HDX 7" & 8.9" General] Strapples:
https://www.youtube.com/watch?v=GHI7ED6pUPY

This is what worked for me.

1. Prepare ADB or get it if you need it. It is HEAVILY relied on

2. Take the FireGapps folder and unzip it

3. Enter ADB and go down the list installing EVERY APP IN THE FOLDER using adb install command.

3. do this

adb shell

pm grant com.google.android.gms android.permission.INTERACT_ACROSS_USERS

4. Unplug from the computer

5. Tap the icon for google play services to force it to start

6. Open Google Play Music and enroll your google account

7. Restart Kindle

8. Open google play music and play something or use a google app

PLAY STORE DOES NOT FUNCTION. It requires Priv-App which we cannot do in Kindle Fire OS, all other GAPPS are as far as I can see.. working. Hangouts is tempermental I am still looking for a version that will work on Fire OS. Stay tuned on that.

If this works please THANK my post :)
[Kindle Fire HDX 7" & 8.9" General] rien-ne-va-plus:
Amazon is unwilling to roll back my device, so I guess I can still sideload the apps I need? Will give that a try.
[Kindle Fire HDX 7" & 8.9" General] DivinityCycle:
This is pretty interesting stuff.

I was only able to sign into my Google account on my Kindle after I disabled 2-Factor Authentication on my account.

I used 1market to grab some updated Google packages, including a newer Google Play Services, Chrome, YouTube, Drive, and some others. A bunch of the APKs in the FireGapps package from that YouTube video were not up to date.

Google Calendar is fully working, all my events synced over.

The Google Camera app is working, but I'm not sure about location tagging and suspect it is broken.

Similarly, Google Maps is working, I can get imagery and also my bookmarked locations synced over, but the app cannot get my location. It's acting like it does not have access to Location Services.

Google Chrome works and I have Bookmarks and History synced over from my account.

Google Drive and the dedicated "editor" apps Docs and Sheets are working.

YouTube is fully working, I have full screen video playback in HD and account sync, so I see my "Watch Later" and subscribed channels.

Gmail is fully working, just took a moment to sync in the email from my account.

Google Plus appears to be fully working. The "Photos" app that comes with it is also working.

Google Hangouts goes to a "Signing In" pop-up that just spins and spins when I try to launch it.

Chrome Remote Desktop is working perfectly.

Google Earth crashes at launch.

Play Games seems to be behaving normally, although the only games I have aren't working properly due to the failed license checks, I can see my profile and achievements as normal.

Google Keep is fully functional.

The Google Search app crashes at launch. I had a version of this working at some point in the past, so it's not clear to me what's broken about this.

Play Books is working and I have my full library syncing (my #1 priority on this project since I wanted to use my Kindle HDX to read books and comic books).

I can't seem to get Google Wallet to work. I'm pretty sure I have the latest version, but when I launch it, it says "This version of Google Wallet is no longer support, you need to get the latest version".

Play Music is fully working, I can stream my library with no issues.

The "Voice Search" app does actually work, even though the main Google Search app is not working for me.

I'm having some issues getting 3rd party apps to "validate" my licenses (Hue Disco, Plague Inc, and ComicRack were the three I have had issues with so far).

The "alarm" app I am using is called Timely, and it makes use of Google for cloud sync. This functionality is working :D

The weirdest thing to me is that I have installed Nova Launcher and set it as my default Home screen.

However, EVERY TIME I press the Home soft key, I get a pop-up asking me to select which Home app to use.

Anyone else working on this silly stuff with the Saturn? I feel like I've mad enormous strides in terms of desired functionality already, and
[Kindle Fire HDX 7" & 8.9" General] iattilagy:
So you mean that you rolled back 4.5.2 to 4.5.1? That's exactly what I need. Or you just flashed 4.5.1 over 4.5.1? Because if I rolled back to 4.5.1 amazon would roll it back to 3.x.x.
[Kindle Fire HDX 7" & 8.9" General] AmazonLeaker:
To all the people thinking to get roll back let me tell you all loud and clear Rollback is possible if and only if you are in 4.1.x above that nothing will happen,however Amazon.de or .jp or .ca or .cn or .fr sites operate independently so there might be thin chances that you may get the device rolled back if higher then 4.1.x is BUT amazon has withdrawn OR removed the tool of downgrade and only software developers have the access or right to that who will determine if a rollback is really necessary after examining the logs of device so technically speaking there is no need of rollback according to them.....so just be clear for now if you have 4.1.2 or so is then rollback is possible if above that the answer is a Clear NO who ever you may speak to its the final resolution in case you feel that you are cheated or betrayed by amazon for this then please compare things with apple or other manufacturers who charge good money for same think you get for a lesser price + benefits of prime etc etc...though this doesn't mean that amazon is not making money...it is but at the same time providing facilities too....

And in case you seriously want to change things then start a campaign for real to get the unlocked bootloader that would solve the issues forever....

As the word of Saturn has come here I'd like the owners of Saturn to please update this thread when in case a root method works also Saturn owners can show their interest over the possibility of root basing on which some developer may start some work or investigation...

Adding to this are there any Owners of Ariel (Fire HD 6) & Aston (Fire HD 7) [THE NEW GEN OF FIRE DEVICES]

Ariel is based on MTK chipset and Aston on OMAP or may be reverse, so considering MTK, I think that root would be easy via SP flash tools or so.... but still an assumption...so owners of Ariel and Aston also are welcome (Would open a specific Thread soon basing on responses because considering their prices having a custom ROM would be great value addition )

NOTE : KINDLE FIRE OS IS CRAPPY AND I FEEL THAT ITS NOT WELL OPTIMISED SO BETTER OF OF THR HARDWARE OF FULL POTENTIAL OF YOUR DEVICES CAN BE USED ONLY VIA STOCK ROMS OR CUSTOM OR CM ROMS
[Kindle Fire HDX 7" & 8.9" General] libelah:
I received my rollback from 4.5.2 to 13.3.2.7 after 8 days (including some non-working days) now.

After that I followed steps 1 to 9 from this tutorial:

https://www.youtube.com/watch?v=ZcD5mjZK0gU&list=UUbu3lmLz5QGaxHTeC6Yw5tw

Then I flashed nexus rom to stock slot from here

http://xdaforums.com/kindle-fire-hdx/development/apollo-nexus-v1-1-t2835838

which worked perfect!

Now I am on Android 4.2.2 :)

I wondered how to setup multiple user accounts which should be possible from 4.2.2 on but could not find anything. Anyone having a clue?

I also wondered if I can flash this rom:

http://xdaforums.com/kindle-fire-hdx/development/cm-11-20141216-unofficial-thor-t2974818

which is Android 4.4.4. But if I understand it correctly I have to downgrade to firmware 3.2.4 first - is this correct? If yes,is it possible?

I mean the same precondition was mentioned for the nexus rom and it still worked...

How'd u get it to roll back?
[Kindle Fire HDX 7" & 8.9" General] libelah:
As I wrote in my first post I contacted Amazon customer support by mail and chat. First they told me downgrade was not possible, then suddenly they told me it is - just the way it was already explained here multiple times.
[Kindle Fire HDX 7" & 8.9" General] jimyv:
has anybody else heard about this latest update killing devices without being rooted or customized in any way? My mothers and her best friend both Kindles died after latest update..and they did absolutely nothing custom to them on stock the whole time. They both talk to Amazon and Amazon tried everything to revive the devices but they would not stay working well so they replaced both of them. Maybe this is why they are so willing to roll back at first hint of problems
[Kindle Fire HDX 7" & 8.9" General] p1gl3t:
No, I didn't rollback from 4.5.2 to 4.5.1. I already had 4.5.1 and tried flashing the same version as that was the safest bet to test the version check bypass.

You can't and SHOULD NOT TRY to downgrade from any version of 4.x.x to any other version besides the ota's that Amazon provide for downgrading. You will certainly brick you device as I did with mine.

The problem is that by flashing an OTA you also flash SBL1 (secondary bootloader stage 1). If you flash a 4.x.x rom some fuses will be set in the SoC preventing bootloader downgrade. As there is no way going back from this, I am pretty certain that the bootloader that comes with the 3.2.7 downgrade OTA has a version number at least as high as the 4.5.1 OTA.

I think I should be possible to obtain the OTA from devices that have been downgraded from 4.5.2 (such as [MENTION=6031766]Ali Ejea Mc[/MENTION]). This makes me think that by reporting the 4.5.1 version number from a device that was previously downgraded to 3.2.7 and rooted, the 3.2.7 OTA will be once again pushed and could be read from /cache (remember we have root). Unfortunately I don't have the means to test this hypothesis myself.

I also think that it might be possible to bypass the OTA signature verification, at least at the OS level. This unfortunately wouldn't be of any help if the recovery also checks the signature. Does anybody know about this? I must admit I didn't look at all into the binary.
[Kindle Fire HDX 7" & 8.9" General] jimyv:
maybe

A simple build prop mod like we were doing in the earlier rollback threads from earlier firmware ..should be enough to initiate another download.. it would ultimately fail or screw something up but I believe it was still download it just by doing that. then snatch it and remove it from device..
[Kindle Fire HDX 7" & 8.9" General] gqukyo:
And people are saying they are not allowing it so I just asked how you actually did it, not others so cool it dude. Your statement "I received my rollback from 4.5.2 to 13.3.2.7 after 8 days (including some non-working days) now." doesn't really explain how you got it to roll back. Giving more details about WHEN they actually did it and WHY they "suddenly" told you they will after saying no might help as well so others can tell the rep if they do try.
[Kindle Fire HDX 7" & 8.9" General] kingpin32:
Just got my device rolled back from4.5.2 to 3.2.7. Just chatted online with a specialist. Told them I was unhappy about being automatically updated without being given a chance to check out new update before applying it. Rep was very helpful. Rolled me back and told me it would be permanently left on that version of fire os3. No more ota updates for my device. Took less than 40 minutes to get downgraded.
[Kindle Fire HDX 7" & 8.9" General] gqukyo:
That's great news, seems like they are willing more easily now.
[Kindle Fire HDX 7" & 8.9" General] libelah:
I'm sorry, I really did not meant to sound rough with my answer! It seems I was not precise enough - my first post was this one:

http://xdaforums.com/showpost.php?p=57773240&postcount=149

Anyway: I just kept asking for a downgrade again and again. Furthermore I told them that I am having issues with apps and reboots since the upgrade and that it worked well with FireOS 3, which are the arguments that were already written down here in the thread. Also I told them that I have read in "the internet" :) about people who have sucessfully received a downgrade so I insisted on the fact that it has to be possible somehow and asked if they maybe could forward me to their colleagues from technical support. The last chat was at night and the supporter told me after some time I should contact them again at morning, as there are no supervisors available at the moment. So when I entered the chat next morning the supporter (supervisor?) immediately asked me if it already was explained to me what a downgrade means (=receiving no more OTA-Updates). After accepting this he said he would forward the request to the tech-Guys and that it might take some days. Thats it. I did not ask why it was not possible at first.

Hope this helps!
