if still on 5.1.2 you can use kingroot to gain root (google kingroot on device and download). you can follow instructions in another part of this forum to load the Google Play store and it will function as a normal tablet. Because of the 'bad' serial you will not be able to link to an amazon account or use any amazon based app/service unless you do it thru the internet browser. at moment as far as i know, there are still no custom roms for the saturn version 8.9 hdx. if unaware, the serial is 'bad' as the original owner never 'unlinked' the tablet from their account and they are the only ones who can, or it was stolen and sold. same as a phone being 'blacklisted'. i have the same tablet and the same issue. i bought it on ebay and did all above. works perfectly fine.

Hanging at "Fire" logo

Greetings, my device is a 4th gen, 64GB, Gapps installed, FireOS 5.3.1, launcher changed to Nova Prime, rooted with Kingroot 4.9.7. I was in the process of removing Kingroot in favor of supersu (using SuperSuMe per guide at Missing Tricks) and all was going well up until the recommended reboot after supersu updated binary. Now it gets to the animated "Fire" logo and there she stays. Is there a possible fix or is it time to contact Amazon? I greatly appreciate any help.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Known glitch with SuperSUme and FireOS 5.3.1; reboot is deadly. No known fix other than reloading FireOS from recovery which isn't possible on locked HDX models. Best contact Amazon for a warranty exchange.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] ch1potle:
Thank you very much for your reply and the quickness of it. Another question if you don't mind - what was the correct move at the point (or just before?) I was at? After getting a replacement I am almost certainly going to keep pursuing transforming this device into as close as possible pure Android.

I bought this tablet 7 months ago for about 480USD and at one point I was looking to get rid of it so I investigated Amazon's "got one to sell?" link to find out that they would buy it back from me for 40USD. I sold them back a used Galaxy S4 and they gave me more for it than they would the Fire!

Thanks again :good:

once supersume was run there may not be a fix even before rebooting

possibly installing SafeStrap or reinstalling kingroot...

seems unlikely that it is still under warranty
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
As noted by [MENTION=4267571]sd_shadow[/MENTION] there really isn't a fix once the Supersume curse has been cast. Other Amazon devices can reload FireOS via the stock recovery menu to revive the device. For whatever reason Amazon opted not to include this essential capability on the high-end HDX model line. Once FireOS is borked the device becomes a throw-away unless unlocked or still under warranty. As for the latter it really depends when and how you purchased it. NEW units in the USA come with a 12 month warranty; others 0-90 days depending on sale terms (eg: Amazon Warehouse).

If you do obtain a replacement you can still root and stick with KingUser. It does a reasonable job and has some features not present in SuperSU. Just avoid the other add-ons like Purify, alternative market places, etc. Once rooted you can add a firewall to monitor and block any outgoing KingUser communication if concerned (there is no creditable evidence that it leaks information if you avoid the other crap).

No custom ROMs for 4th gen devices; best you can do is a Partial GAaps install which includes the Play Store for access to Google's vast app portfolio.

p.s. If you can talk Amazon into sending a 3rd gen HDX your options expand considerably as those devices can be unlocked and are capable of running several custom roms including CM (11, 12.1, 13), SlimLP and Nexus (currently 4.x; 6.x under development). You can compare differences between 3rd/4th gen on Amazon's site. There are almost identical; 4th gen uses a slightly faster processor which is virtually undetectable under normal conditions.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] ch1potle:
Thank you for your reply. I bought the device new so Amazon will "repair or replace", at their discretion. I did inquire about the 3rd generation but I was told the warranty only provides same devices. I will do as you said with Kingroot, gapps, and Nova Prime with the replacement. I was pretty happy at that point before curiosity got the best of me and I borked it. Cheers :good:
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] ch1potle:
So get this, they replaced my HDX with a brand new Aluminum-backed HD 10. It's kind of a cool device but doesn't compare to the HDX. Half the RAM, half the screen resolution, CPU frequency is less by 1 GHz (this may not be a big deal as the CPU in the HD 10 is likely more advanced), but what irks me is the price difference between the devices - $429.99 for the HDX, $304.99 for the HD 10. I contacted them and expressed my disappointment and they suggested I give the HD 10 a few days of use and if then I am still not satisfied I can send it back and they will credit me 80% of what I paid for the HDX. Alexa is supposed to be rolling out to HD 8s and 10s so once the HD 10 receives "her" and I can evaluate the device with Alexa I will almost certainly return it and get a Samsung Tab S2 9.7"
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Half is being generous. HD 10 is just a giant budget class device with an inflated price tag. Reminds me of the big screen, low spec laptops you find at Walmart. I'm no device snob owning several low end tablets including the 5th gen Fire 7. They're great for specific tasks but don't hold a candle to a higher end HDX. I'd take the 80% refund and look for a used 3rd gen HDX which can often be had for cheap. That said, the Tab S2 is also a very nice device. Good luck.

How do you boot the 4th gen into stock recovery?

Thanks
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Same way as every other Android device: <power>+<vol-up> from a cold start.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] donharden2002:
For some reason I can't get this thing to boot into stock recovery using the button combo.

Screen just stays black, then I hold the power button for about 30 seconds to get it to reboot.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Possible stock recovery is damaged or inaccessible. Try booting into recovery using an app. Quite a few choices in the Play Store.

Hi,

I've just downgraded to 3.2.8. Would you recommend upgrading the firmware to 4.5.2? If so what gains would it bring? I'm installing CM13 currently. Thanks in advance!
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Nope - no benefit. Be sure to keep WiFi off (except for a few seconds while rooting) to avoid an OTA update that will permanently brick the device. Root with TowelRoot, not Kingroot.

Does from power off

Power + volume down

Boot the deviceto fastboot/bootloader?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] EthanG_1988:
Sadly, no.

From a powered off state: I tried hitting power+vol dwn, and released power at first sign of life, (held vol down)....eventually the tablet just booted into fireos. Recovery never came.

I also tried holding vol dwn from a powered off state, then hold power button, and it still just booted into the os.

If I try holding vol up+power from a powered off state, the tablet "freezes" (screen never comes on, and power button has to be held 30 seconds to get kindle to boot).
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] sd_shadow:
So FireOS is still booting fine?

If so, and device is rooted,

you could try setting up ADB and use

abd reboot-recovery

For setting up ADB see

Fire Index: Which Amazon (Kindle) Fire Do I have?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] EthanG_1988:
Yes, FireOS does boot fine. I already have ADB setup, and I can boot into recovery from ADB no problem. The only problem I have is that I cannot manually boot into recovery from power off using button combo. If the tablet ever bricks, I wont be able to sideload the update from recovery, because I wont be able to get in from power off state.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] sd_shadow:
I would ADB reboot bootloader

And go ahead reinstall firmware,

see that fixes the issue

Just be careful about what firmware version you have

Downgrading can hard brick in some cases
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] EthanG_1988:
Does the stock firmware that Amazon provides include the recovery?

I downloaded the 5.3.1.1 .bin for the 4th gen 8.9 hdx, but I don't want to flash it without knowing what it is installing. Obviously fireOS, but boot image/recovery image/kernel?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] sd_shadow:
I thought it did, but I will check

May take awhile...

The .bin is just a .Zip compression format

If you want to look
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] EthanG_1988:
I just extracted the 5.3.1.1 update, and I do not see a recovery.img anywhere.

I don't think it is worth flashing anything at this point. There has not been any successful root method for 4th gen 5.3.1.1 as far as I know, so I will just accept that the stock recovery is only accessible from ADB.

Thanks for your help.

Yep, I actually followed those instructions yesterday, and I even commented with some questions on the thread.

Unfortunately King-o-root fails. Tried 5 times, and it failed at the same percentage every time.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] EthanG_1988:
Since that method does not work for the HDX 8.9 4th gen on 5.3.1.1, is there any way to roll back my firmware to 5.3.1.0 (it seems as though it would be easier to root that version)? I cannot find that firmware anywhere for the 2014 HDX, and amazon only provides the 5.3.1.1 firmware on their website.

Also in regards to entering the recovery on my tablet with a button combo, it looks like the answer to my problems is in post #53 and #56 of this thread. Davey126 said that Amazon chose to lock the recovery for this specific generation of tablet.

I saw that in a different thread you had compiled a very good list of different firmware versions with download links, does such a list exist for the 2014 8.9 HDX?

[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Unless prepared to throw away the device FireOS rollbacks on 4th gen HDX device should not be attempted. 5.3.1.1->5.3.1.0 rollbacks are unproven thus assumed to be fatal with no possibility for recovery. Many FireOS builds have anti-rollback provisions that cripple (hard brick) the device vs. simply rejecting the attempt. Thanks, Amazon.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] EthanG_1988:
Thank you for the response! I will just keep using this tablet as is for gaming and entertainment. At least I have access to google play, and I was able to make Nova Launcher the "default" launcher using launcherhijack. It's a shame though, this tablet must be a powerhouse when rooted.

Hi guys, ive been looking for a new tablet now for what seems ages.anyway i always come back to the hdx 7, the chips inside modern budget tablets are rubbish to say the least

you can get the HDX for about £50 online now, is that good??is everything a pretty straight forward process to get to using a custom rom stage, also what is the better rom to use..non working cameras arent an issue really, i intend to just play games, thanks, and yes i am a noob
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Both 3rd gen HDX models remain competitive in market ripe devoid of higher end offerings. Unlocking the bootloader (prerequisite for custom ROMs) can be tedious for some but is not exceptionally difficult. Recommend going with CM 14.1 (Nougat) as it is the only custom ROM under active development.

Pricing is location, timing and supply dependent. You can spot a 'good deal' based on competitive offerings on auction sites. Keep in mind a 3 year old device will have a 3 year old battery. That's in the timeframe when consumer grade lithium ion batteries begin to deteriorate regardless of usage.

IMHO £50 seems about right (~65 USD).

Hi Guys , Noob friendly question going to be asked..:

i notice kingroot should work on 4th gen fire HDX 8.9" FW: 4.2.2, just wanted to confirm if there any issues when rooted changing launchers and if theres any risks doing certain things while rooted.

i was going to :

root

disable amazon launcher and amazon add-ons

replace kingsu with supersu

install google play

use nova launcher

disable OTA.

is this do able?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Doable but awkward and unstable. After rooting recommend unlocking bootloader and flashing a custom ROM. FireOS v4 and Google Play Services/Store do not play nice.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] jackvdbuk:
Thanks Davey,

so if i

root with kingroot,

unlock bootloader (is this as simple?)

push recovery/ custom rom

this route should be alot more stable? and less messy/awkward?

thanks again!
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Once rooted unlocking is pretty straight forward using the procedure from this post (also see posts immediately before/after) and the thread OP. It is important to read and comprehend before diving in. Only step #2 is dangerous although establishing fastboot communication can be frustrating due to driver fussiness. Not hard to resolve if you have some experience managing Windows devices and/or working in a command window (aka command prompt).

Also take note that HDXs are not like other 'android' devices you may have worked with. Set aside much of what you may already know about updating partitions. Follow instructions and all will be well; you'll be rocking LinOS 14.1 (Nougat) with full play store access in no time!

Pay close attention to glued areas; easy to crack the screen. Less of an issue on Saturn (vs 7" Thor) as there are fewer glued components but obviously a bigger screen that is less tolerant of flexing. Patience and a good selection of spudgers (example) is key.

Yes, I think so. I was assuming the latest version.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Your options depend on the device generation. All 3rd gen HDX can be rooted, unlocked and accommodate a variety of custom ROMs. Unfortunately, choices are far more limited with 4th gen devices contingent on the version of FireOS currently installed. When your device arrives do not allow it to connect to the network (ie: keep WiFi off); a OTA update will only further restrict your choices. Post the FireOS version; go from there.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] 85thday:
So got it. It was on 4.21 so rooted what ekse can i do now 4th gen
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
FireOS 4.2.1 does not assure root. You'll want to check that pretty quick and block software updates by renaming DeviceSoftwareOTA.apk before enabling WiFi to avoid an unwanted OTA update.

If you are sure it's a 4th gen update it to FireOS v5 for Play Store compatibility. There are no custom ROM options for 4th gen devices. If you wish to retain root you'll need to stop at FireOS 5.1.2 which can be difficult as Amazon usually does not identify the target version when performing OTA updates. There is no mechanism to manually apply selected updates unless rooted which you will loose after every incremental update. KingRoot can bring it back but it's a battle at each step and you'll need to toggle WiFi on/off to avoid another sequential OTA update that may bring your device to an unrootable version of FireOS.

Yet another significant rub: There is no library of incremental FireOS v4 or v5 downloads as the 4th gen community is quite small. Few have rooted their devices given the lack of custom ROMs (still the case) or stable Google Play Store access which was a relatively recent event. By then most 4th gen owners had moved on.
