I did root Amazon Kindle HDX THOR successfully with: [TOOL] HDX ToolKit v0.94:ROOT UPDATE
http://forum.xda-developers.com/showthread.php?t=2665683
And I disabled the air updates according to the instructions. Later I tried to reset the update to 13.3.1.0.
http://forum.xda-developers.com/showthread.php?t=2782159&page=10
It worked allright, until I tried to do the manuel update. But because I disabled air update earlier, Amazon Kindle couldn't find any update the manual update failed. How do I do to enable the update again, is there anything else I can do to solve this?
Is it possible to reset to 13.3.2.3.2 again?
Thanks!

Rerun the tool kit it has a reenable option. Just out of curiosity did you ask this question back in the HDX utility thread? Nevermind it might not of let you post their.
Anyway if as long as you are using version .94 should work fine for you. And make sure that you have Wi-Fi disabled and even forget your network as you are planning on doing a manual update. If you plan on trying to rollback we advised not to at this time just wait till safestrap is updated and works with the newest firmware... Way too many people are breaking their devices by trying to do the build prop modifications necessary to do these manual updates.. If you want the latest firmware just let it up to Wi-Fi nHit check for updates then you can wipe it root it or whatever... But just to let you know currently safestrap does not work on newest firmware..yet. Just do your homework because there are a ton of brick devices right now that are getting sent in for BS warranty claims.. And I have to emphasize yet again there is no easy way to recover this device at this time if you mess something up unless you are using safestrap and on slot 1 ect...NO fastboot capabilities at this time..And bootloader is locked
Thanks

My advise, don't try rolling back, most likely you will brick your device. Search for an app called kindlefree if Google play is what you want.
btw, thank you for posting in Q&A.
I can't seem to find any working root for my kindle and i'm need help to root this darn thing.
I really want to Get rid of amazon and go get Android kit-cat and use the Google play. Your answer will be thanked if your answer works.
i heard about roll backing my kindle fire hdx but i need more info on how to get into the internal storage folder.
My kindle runs Fire os 4.5.4
I have no idea how to find the firmware...
As of now, it cannot be done yet. Sorry.

Oh ok..
Its been a long while though.
I guess amazon won the war against rooting...:crying:
This is a brand new update. So, it actually has not been that long. There has been a root found for almost every other release including 4.5.3, but I think they patched it with this new release.

4.5.3? You sure because i Looked everywhere for answers only to find out the roots does not work... But i hope they find a root.
By the way can you reply to me when they have a root out for my 4.5.4 Update. make sure to give me the link. That will be really Nice.
You should be reading through the boards yourself. If you had, you would know they found a root option in China which worked on 4.5.3. It did take a while to find, but they found one.
I can't just hotlink to a file or post because this device is so fickle, you need to understand what you are getting into when you root. I have been on Android since 2.0 and I have never seen a device so easy to ruin and difficult to fix. Sorry.
That Chinese root also doesn't work 100% of the time. It didn't work on my Saturn(HDX 8.9). That said, I seemed to be the only one who had trouble with it.
The update for 4.5.4 came out in the last week.

I actually did get root to work with Kingroot, prebuiltgmscore apk downloaded separately here and minimal google bundle here
I have a 8.9 HDX 4th generation also called Saturn.
Did Kingroot work with 4.5.4?? If so, I will try it again.

No, my device is a kindle fire hdx 7, it runs 4.5.4 and it seems like kingroot does not work.
When it fails it gives me this Email Icon with a check mark
and then a number 13096
i even checked it with a root checker and it said no Root access
So that's the error screen. Hope they find a root for 4.5.4 Soon!

There is a way: downgrade to 3.5.8 (there is a thread for it) then upgrade to 4.5.3 then root it with kingroot.

Use great caution if going this route. There are numerous reports of bricked devices following 3.2.8 rollback apparently due to an immediate ota push of 4.5.4 which renders the device unusable. To date there is no known recovery method. If you opt to downgrade you must either block the ota mechanism via HDX Toolkit (other methods do not work) or take steps to prevent network connectivity until 4.5.2 is successfully installed.

Not at this time. Nor is there a benefit relative to 4.5.2. If you are on 4.5.4 you can roll back to 3.2.8 then upgrade to 4.5.2. However, there are risks involved (unrecoverable brick); procedures must be followed exactly.

Sorry - Saturn devices can not be rolled back. The OTAs used are specific to Apollo and Thor. Amazon never offered rollbacks for Saturn thus no one was able to capture the rollback file. The internals are sufficiently different that you'd likely build a brick if you tried to 'force' an Apollo update. Apologize if I missed a prior reference to Saturn and falsely got your hopes up.
I have been working on a new version of Safestrap. This aims to allow devices that aren't unlockable and running update-kindle-xx.4.5.2_user_452004120 to install HDX Nexus ROM v4.xx.
I am looking for a Thor and Apollo tester to confirm that they can indeed install Nexus ROM v4 with this.
I have confidence that this works, but if you agree to do this please understand as usual that you do so at your own risk.
So far the new version has been tested on unlocked devices to confirm compatibility and works fine.
The next stage is to test on locked devices, which as I have said have high confidence that it will work.
The prerequisites for test are:
- Must be running stock update-kindle-xx.4.5.2_user_452004120 firmware
- Must be rooted
Things to be aware of with the new version:
- Secondary slots boot, but the WiFi module does not load
- Since the secondary slots work but have no WiFi, you will need to flash Nexus v4 to the stock slot
Let me know if are interested in helping with this.

Congrats!! Rolled the dice and won!
Be mighty careful around the 4.5.2 update. Those who received it via OTA (may have been 4.5.3/4.5.4) were treated to a hard brick with no known resolution. Best do the update manually using the procedure/files outlined in this thread. Stay off wifi until 4.5.2 upgrade is complete.
Saturn is fine with 4.5.4, but I assume you are talking about apollo/thor

my device had no safestrap but it was rooted decided to let it auto update so turned on wifi and checked for update. the update centre said no update found, so went and downloaded 4.5.2 from amazon that was taking a lot longer than it should. checked the update center again. a glitchy 4.1.1 was downloading with the download bar glitching from view. i then let it continue pausing 4.5.2 download it then promptly rebooted and attempted to install 4.1.1 the screen went black through the update. hard brick.. i have my warranty and i have another one coming.
here's a tip don't update to 4.1.1 if you are rooted.
hoping to get a kindle with <3.2.6 my first one was originally that <version

For the benefit of others ...
NEVER take an OTA update on 3.2.8. Every reported incident has resulted in a hard brick. Keep WiFi off until OTA is blocked. The only effective method is via HDX toolkit. Renaming otacerts won't work on 3.2.8.
@ggow Any idea when this version will be released for Thor or if I could help test it? It would be awesome to have 4.5.2 with Safestrap.

Hello,
I was rooted running OS 4.2.2 and everything was great until one day I came home from dinner, got out my kindle and saw the dreaded message: "OS Updated to 4.5.4." I forgot to disable OTA! I can't believe I made such a silly mistake, but now I'm wondering if I can rollback 4.5.4 to 3.2.8, and then update to 4.5.2 and root. Does this only work for 4.5.3, or is it possible on 4.5.4? If it is possible, can someone link me to instructions?
Thanks,
Zman8881
Update
I talked to Arun from Amazon support who said it's not possible. He did, however, credit my Amazon account with $5.00 and tell me that an update resolving the inability to rollback will be available soon (EDIT: he later said 3-4 months, nevermind...) , meaning hope for myself and all of you out there who made the same mistake that I did.
EDIT: Is there any backdoor way to downgrade that someone can think of? I have no use for this device without a root, so I'm willing to risk bricking it.

The 'classic' 3.2.8 rollback method has reportedly worked for some. There does not appear to be any harm in trying; your device will either accept/recognize the file or not. Obviously follow all the usual cautions if you are successful (eg: keep WiFi off at all times!).

I highly doubt Amazon is addressing the rollback issue. Why would they do that? The tech had a good laugh at your expense. Best path (aside from attempting a 3.2.8 rollback) is to enjoy or shelve your device until a root exploit becomes available for 4.5.4. You will need to keep it off the network as Amazon will undoubtedly push new updates that will be root resistant. And no - there is no known (or at least well communicated) way to root 4.5.4 as of now.

Can you by chance link me to instructions and/or the link for the 3.2.8 rollback method?
Okay, so here is the rollback file, but I urge you to proceed with caution. If you let Amazon update this build, you are ensured a brick. You need to use the hdx toolkit to block OTA on *.3.2.8.

Relevant thread here. Basic procedure is described in the first post. Take care to insure your device can not connect after rolling back to 3.2.8. Keep the device in airplane mode and/or disable wifi. Depending on the method used to root 3.2.8 and 4.5.2 you may need to enable network connectivity momentarily during the rooting process (typically no longer than 30-60 sec). Be sure to turn it off immediately after. There is no need to block OTA on 3.2.8 if your intent is to immediately upgrade to 4.5.2. That said, if you do receive an OTA update on 3.2.8 your device will brick (unrecoverable). The consequences on 4.5.2 aren't as grave: you'll simply be updated to 4.5.4 and have to start the whole process over again. Ultimately you will need to block OTA once on 4.5.2 but that can only be done after obtaining root.
BTW - once on 4.5.2 (rooted) you now have an option to run a custom version of Nexus 7 which presents a much different interface than FireOS. Risks are low and you can always return to FireOS if you don't care for Nexus. There are several distinct advantages to Nexus including full access to Google Services (including play store) and no worries about blocking OTA and/or receiving an update that breaks root. Everything works except LTE; that's being worked on now. More info here.
Good luck.

Hey - congrats on the win! The rollback file goes in the root of sdcard when viewed from a tool such as ES File Explorer. If you have tethered your Kindle drop it into "internal storage" which is the base folder when viewed from Windows. After the file is in place reboot. If nothing seems to happen (give it 5-10 min) use the 'check for updates' function from within FireOS (located somewhere under settings). At some point the file will either be recognized/processed, recognized/rejected or ignored all together. Post back your results.
Although it has probably been burned into your brain be sure to do whatever is necessary to prevent network access if your Kindle rolls back to 3.2.8.

I thought I did it, but after I hit update, I was stopped by an error message telling me that an update isn't possible because the update I'm trying to install is an earlier version than what I have on my device.

Sorry it didn't work. There is a way around that message but you need root to make the change. Catch 22.

Hey, Davey126, sorry to post here again quite a while after it's relevant, but I had a couple more questions.
You state here that you just have to make sure the wifi is not enabled, so OTAs aren't pushed. But another user (below) seems to push that I'll have to use the HDX Toolkit--which I can't seem to figure out how to actually use; is just disabling the wifi enough to keep it from bricking from an immediate OTA after the rollback?

Okay, so here is the rollback file, but I urge you to proceed with caution. If you let Amazon update this build, you are ensured a brick. You need to use the hdx toolkit to block OTA on *.3.2.8.

I haven't actually tried to get the update to be recognized yet, because I want everything to be sorted out question wise before diving in, but let's say it works and I get my kindle to roll back. How would I then get it up to 4.5.2?
Sorry for the questions! I just can't seem to find the answers anywhere else.

Hey, Davey126, sorry to post here again quite a while after it's relevant, but I had a couple more questions.
You state here that you just have to make sure the wifi is not enabled, so OTAs aren't pushed. But another user (below) seems to push that I'll have to use the HDX Toolkit--which I can't seem to figure out how to actually use; is just disabling the wifi enough to keep it from bricking from an immediate OTA after the rollback?

Good questions; I appreciate you looked around before posting. If your intent is to rollback to 3.2.8 and then immediately upgraded to 4.5.2 there is no need to block OTA updates on 3.2.8 provide WiFi remains off (as an added precaution I would keep your device in Airplane mode). However, you'll need to enable WiFi for a few seconds while rooting. While that's not enough time to download a complete update a file fragment could potentially cause complications. Hence an OTA block could be beneficial. Really depends how fast you work and whether you can detect an incoming OTA update. You'll need to remove the block before upgrading to 4.5.2.
HDX Toolkit is a tethered solution. It runs on a Windows host and requires USB debugging to be enabled. Commands are issued to your device via the tether. Nothing needs to be installed on your device. You will also want a working tether to copy the 4.5.2 bin and possibly other files to your device when it's time to upgrade. Some folks load everything on the device in advance but I prefer to copy files as they are needed.

Gotcha!
Actually, thanks a bunch for not only explaining the tool a bit, but prompting me to go take another look at it. Turns out I was downloading the wrong batch of files--everything seems to be working now. You just tether your kindle and tell it to block OTA, right? Don't have to worry about version number or anything like that?
So with upgrading to 4.5.2, is the process pretty well the same as with downgrading to 3.8.2? If so, where can I find the update file?
Thanks a million!

HDX Toolkit only works on FireOS v3 (3.2.8 and below). After rolling back to 3.2.8 tether your Kindle and use the toolkit to block OTA. Once OTA is blocked you can enable WiFi and use towelroot to root. Gather any other files you may need on your device, disable WiFi (also recommend 'airplane mode') and then use the toolkit to reenable OTA (under '5 More'). Move the 4.5.2 bin (here) to the root of sdcard and check for updates. Once on 4.5.2 you'll need to root and block OTA once again. Check the forums for the appropriate tools and method for FireOS v4. Kingroot and renaming DeviceSoftwareOTA.apk seem to be the most reliable.

Okay, thanks so much for all the information! I actually just got my kindle to rollback to 3.2.8, but this brought up two more questions for me.
With the HDX Toolkit, it's asking me to grant root access on the device, which I can't do yet until it blocks OTAs; despite this message, it seems to go through and, after displaying the same message 5 times, state that OTAs are blocked. Is there anyway to safely check that they've actually been blocked? Also, is doing it twice okay? The message seemed less than assuring, so I did it again, but it displayed a different message 5 times on the second attempt.
Lastly, I want to root 3.2.8 and /then/ update to 4.5.2, right?
Thanks so much!

The OTA blocker in HDX Toolkit is very comprehensive (probably overkill). Some actions require root, others do not. I suspect OTA is effectively blocked but there is no way to conclusively test. Suggest rooting with towelroot (you'll need to toggle WiFi momentarily) and then run the OTA blocker again. Multiple executions should have no adverse consequences. While unlikely to happen watch for any signs of a download in progress. If you see it turn off WiFi and post back for further instructions.
Remember to undo the OTA block after the 4.5.2 bin is in place; otherwise your device won't 'see' it.
Technically you don't absolutely have to root 3.2.8 to upgrade to 4.5.2 but I find it much easier to move files around and take corrective action if something goes wrong. Downside is root gives you unfettered access to everything; navigate carefully.

Alright. I think this is the final question before I go through with everything: on rooting with Towelroot, can I just use the HDX Toolkit for that? It says it only works up to 13/14.3.2.6 and below, so I just want to be safe.

Neither Towelroot nor HDX toolkit has changed much (if at all) in the past 12-18 months. The version range was likely current when coded. It can't hurt to try; it will either work or not with no side effects. If it doesn't work head off to towelroot.com for the official variant. Obviously this means keeping WiFi on for a longer period.

Got Towelroot to go through, despite a weird error the first execution. I didn't seem to have to enable wifi at all, believe it or not, and HDXTools said I was properly rooted.
I've been searching for the past hour or so, but I can't for the life of me find anything that clearly states how to go about rooting 4.5.2 once I get my kindle updated. I've found the supposed root file through the rollback thread, but I can't find out how to actually use it. As for Kingroot, I can only seem to find threads for 4.5.3. Can you impart any knowledge to me about this?
Also, in trying to find the solution, I found another post by you:
Davey126 said:
You'll need to follow the guide linked by ggow (here) which is rather technical and requires a Windows host to complete (there are variants for Linux and OS X) plus a fair bit of technical knowledge. There are no canned tools, videos or step-by-step tutorials. Unlocking is not risky (failed attempts won't harm your device) but it can be a frustrating experience.
If unlocking feels uncomfortable you can do a controlled upgrade to FireOS 4.5.2 and then install Safestrap v4 followed by Nexus v4 or CM11. However, you will permanently loose the ability to unlock your bootloader which is the key to running roms like Nexus and CM in 'native' mode. Unlocking also offers greater recovery capability should something go wrong.
There is also the 'do nothing' option which leaves you with a perfectly serviceable device running a very nice Nexus rom (Jelly Bean 4.2 based).

From all that I've read, it seems like we can only go back as far as 3.2.8 now. Is it too late to unlock the bootloader? Sorry for bringing an entirely different thread here, haha--I just want to make sure I get everything done in one fell swoop.

Surprised about that but glad it worked! Perhaps the version built into HDX Toolkit contains the bits & pieces that normally require online access.

Kingroot works great on 4.5.2 and is far easer than the alternative methods. Some question the origins of Kingroot (China) but the tool is widely used across a variety of platforms. Personally I could care less where it comes from as long as the reputation is solid. Sharing this in case you have a different perspective.

As your start point was FireOS v4 your device was never eligible for bootloader unlocking. More specifically, Amazon fixed the vulnerability that allowed bootloader signature forging in 3.2.4. Clever folks figured out how to roll back to 3.2.3 up through 3.2.6. Starting with 3.2.7 Amazon became aggressive about blocking rollbacks. Any attempt to do so will blow an efuse which is equivalent to a brick. It's always possible another vulnerability will be discovered in higher firmware levels that permits bootloader unlocking. Don't hold your breath.
Heres the deal I have a kindle fire HDX 8.9" (Apollo) On firmware version 14.3.2.4_user_324002120 and was wondering if it is possible to unlock the bootloader.

Yes. Procedure involves a rollback to FireOS 14.3.1.x, installation of TWRP recovery, updating the native bootloader and then working through the unlock procedure (tedious for some). Once complete you can flash several HDX compatible roms including Nexus v4, CM11, two lollipop variants (CM12, SlipLP) or stick with FireOS provided you don't want to install gapps.
If needed I can post an outline and link to contributor supplied guides in a day or so ... or perhaps someone will jump in with the gory details. Or you also can browse through the forums. I'd wait for more info as it's pretty easy to brick your device (no recovery) if you go off script. In no case should you tweak build.prop or flash different versions of FireOS without specific instructions.
"If needed I can post an outline and link to contributor supplied guides in a day or so..."
This would be highly appreciated! Thanks!

With 3.2.4 you could use the rollback images provided by @ggow. Check page 2 of this thread (page 1 is about 3.2.5/3.2.6 users, who can NOT use the rollback images!).
This would require rooting with HDX Toolkit and installing Safestrap 3.75. With Safestrap v3.7x note that factory reset means standard wipe only! Do NOT open advanced wipe menu, and especially do NOT wipe system! Keep WLAN off/flightmode active to avoid getting updated by Amazon, (re-)root and disable OTA via HDX Toolkit after downgrade, then flash TWRP, update 3.2.3.2 bootloader via TWRP, unlock bootloader and flash ROM of your choice - be sure do create a backup of your Fire OS in TWRP and move it to your PC before you flash any custom ROM!
Read the info, and ask first if you have questions, i.e. before you brick your HDX.

You can't. Any attempt to rollback below 3.2.8 will brick your device (anti-rollback protection). There is no way to unlock the bootloader on a device that has been upgraded (or began life) above 3.2.6.
However, with 4.5.2 you can root, install Safestrap v4 and then have a choice of CM11 or Nexus v4. Post back if you need assistance.

Thanks for the quick reply! Basically, I have constant issues with GAPPS running on my rooted 4.5.2 Apollo. For the last six months I have simply blocked any updates of Google Play Services (+chattr command). This was fine for a while, however, meanwhile apps like Google+ & Photos are working less than satisfying. I have updated Google Play Services today which eventually killed my Google Play Store. I managed to get back to the previous so-so state because I had backed up the Google Apps files with Titanium backup. Though my "simple" aim remains to have a working Gapps package on my system. However, the safestrap method, for some strange reason, is currently no option: when I install safestrap 4.1 and try to enter recovery the system goes into a black screen.
To cut a long story short my longterm plan now is to rollback to 3.2.8 again, upgrade to 4.5.2., root and reinstall Gapps manually (or is there a quicker option?). Possibly, Safestrap will work again then too.
Does this make any sense to you?
cheers!

You are in a tricky situation. If Safestrap v4 won't boot the contents in one of the native Amazon partitions (boot, recovery or system) may be damaged. You need some of these components to rollback or upgrade. If attempted outcomes can range from refusing to process the rollback/update file to an unrecoverable brick. You sometimes see this in a pure stock device. Working fine then bricks after receiving an OTA.
Thoughts:
- it is possible to 'refresh' the recovery partition with Flashify but you will need to find a compatible 4.5.2 recovery image
- suggest you upgrade to 4.5.5 first. Based on limited feedback the risk of a minor FireOS v4 upgrade is less than rolling back.
- if the upgrade is successful you can then attempt a rollback to 3.2.8 followed by upgrade to 4.5.2 (keep WiFi off!!)
- you should uninstall GAaps before upgrading/downgrading.
- there is increased risk if you previously changed permissions on system files to block OTA, etc.
- you will need to reenable OTA (hopefully just a file rename) to up/downgrade.
- I believe Safestrap v4 will install and run correctly if you successfully rollback and upgrade to 4.5.2.

Close to (effectively) zero. A new vulnerability would have to be discovered followed by an exploit to leverage it. 3rd gen devices have been discontinued; we don't even have root for 4th gen devices. I suspect few resources are being expended on this device. All the (Amazon) excitement surrounds the new $50 USD tablets that have been rooted and have a selection of custom roms. HDX is quickly becoming a beautiful dinosaur. Hi specs are out, cheap is in.

Am I in serious trouble now?
I have followed to downgrade path by first updating (my 3rd Gen Apollo) from 4.5.2 to 4.5.4 and then to 4.5.5. Next was the 3.2.8-downgrade file:
mod-update-kindle-apollo-14.3.2.8_user_714328020.bin
However, starting this downgrade always results in a "Last update failed" message.
It turns out that there are two different 4.5.5 update files.
update-kindle-22.4.5.5_user_455001820
update-kindle-14.4.5.5_user_455001320
I have updated to the more recent "455001820" which actually refuses the downgrade to 14.3.2.8.
Seems I am stuck now?
Can I at least root update-kindle-22.4.5.5_user_455001820?
Thanks!
UPDATE:
Stuck where I was, I allowed my apollo to go online again. It found a newer 4.5.5 Fire os update and I let it download and run through. It now seems that I am on the latest version of 4.5.5. However, with this setup I am still unable to downgrade to 3.2.8. Every attempt to do so delivers a "Last update failed" message...
AFTERTHOUGHT
Could it make any difference if I factory reset the device (i.e. with regards to the downgrading process)? I have also noticed that I did not uninstall GAPPs before updating Fire OS to 4.5.5. However, I did manage to uninstall Google Apps and then also deleted google related files by searching with ES Explorer.

I do not think the different subversion of 14.4.5.5 are significant in your situation although good to know they exist.
Yes - I would try a factory reset as others have reported success when update (rollback) files fail to process. This is one of the few cases where benefits of a factory reset outweigh risks. Make sure usb debugging is enabled as it may prove beneficial if your device has trouble restarting after the reset.

Thanks, davey126. I have made factory reset on my device. I will try to downgrade later today. With regard to unlocking the 4.5.5. bootloader there has been an interesting development: a couple of days ago somebody managed to crack the 4.5.5 bootloader - unfortunately for the Kindle HD 7 (3rd Gen, 2013) only. What is your guess: could this prove useful for the HDX? Could this become a Safestrap alternative? Is it worth the wait?

Aside from sharing a generational identifier the two tabs have little in common. It's possible there is some similar code in the bootloader...but that seems unlikely. The real issue imo is the number people working on HDX vs HD variants. Only a few talented devs (I'm not one of them) tinkering with the former which is now discontinued.
Installing Safestrap does not decisively close the door to leveraging future BL exploits should one become available. I also think we may see some progress on a LP/MM rom for SS over time. Fingers crossed!

Installing Safestrap does not decisively close the door to leveraging future BL exploits should one become available. I also think we may see some progress on a LP/MM rom for SS over time. Fingers crossed!

Thanks again, Davey126. All is well now.
It all turned out as you predicted: downgrading 3.2.8 was possible after I made a factory reset on 4.5.5.
The rest was easy: upgrading back to 4.5.2 and rooting.
Your second prediction also proved correct: Safestrap 4.0.1 was not working properly on my fire os stock ROM. However, by going through this whole down- and upgrading process again Safestrap couldn't run smoother as it runs now. Finally, a working Safestrap opened the road (Hallelujah!!) to GET RID OF FIRE OS ONCE AND FOR ALL. I am now on rooted CM11 with GAPPS and starting to explore a new, liberated tablet! One more reason to celebrate!
