Finally, my little Kindle is worth using. I put up with Amazon's ridiculous Android version for way to long, so I just threw my Kindle 7" HDX, LTE, 64GB into a drawer and forgot about it. That is until recently, I was surfing the XDA forums to see if anything new had popped up like I do once every other month and boy was I happy I did. I immediately downloaded this ROM and installed it, 20 minutes later I had a complete custom OS, with all of my favorite apps, that just simply rocked. It definitely breathed new life into this little guy. The Kindle HDX series are really nice tablets, unfortunately they were always plauged by Fire OS, which is just a really bad system through and through. Also, why did Amazon discontinue the HDX series, I absolutely hate their new low end tablets, just pieces of garbage in my opinion. Why anyone wouldn't just pay the extra money to buy something like a Nvidia Shield for $200 bucks is beyond me.

Anyway, thank you dearly, here is a screenshot of my desktop in case anyone is interested, SmartLauncher 3 is the launcher, with Rewun theme. The look is perfect for the Kindle 7" HDX, don't you think?

Answered your own question :). High-end HDX models (initially sold at/below cost) didn't drive sales in the larger Amazon ecosystem which is the only reason they sell devices in the first place (with the accompanying 'lock-in' FireOS to help guide the shopping experiece). However, the impulsive buyer Amazon covets is perfectly happy with $50 low-end knockoff that would have been ridiculed if it didn't carry the Amazon name. Keep in mind you, I and the vast majority of people who come to XDA are not the target audience.

Yesterday I got the old "unfortunately Google play store has stopped" and it's still doing it today. Anyone else having the same problem?
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Not experiening this problem at present. Based on post history it appears your device has an unlocked bootloader. Suggest dirty flashing the latest Nexus build (here) which will likely fix the problem and will put you on a supported version of this excellent ROM. If the Play Store issue persists you can try reflashing GAaps (suggest Nano build) which is both easy and safe from TWRP. For reference I

dirty

flashed Fire Nexus Rom from HDX Nexus v4.0.5 with zero (none, nada, zip) issues. As always, be sure to take a backup in TWRP before making changes...just in case.
[Kindle Fire HDX 7" & 8.9" Android Development] Clarke33:
OK thanks. I'll try that tomorrow. I had a long day at work and I'm getting ready to hit the hay or I'd flash tonight. I'll post results tomorrow.
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
re: "For reference I dirty flashed Fire Nexus Rom from HDX Nexus v4.0.5 with zero (none, nada, zip) issues."

I lied. There was a minor startup issue documented here which is easy to fix. Complete forgot about that weirdness ... sorry for overstating.

Ok, so I just factory restored one of my 7" 3rd. generation Amazon Fire tablets. I would love to install this ROM on this tablet, but am not sure where to start. If someone can point me in then right direction, i would appreciate it.

FWIW, I have an Amazon Fire that I have successfully and with no issues installed CM, so I have an idea of what I am doing, just not sure where to start here. Thanks!
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
What version of FireOS? Makes a difference in available options. Also, if you are looking for Nexus you'll be going with this build which is the successor to v4.0.5 which is no longer being actively supported.
[Kindle Fire HDX 7" & 8.9" Android Development] sandman512:
Hey Davey,

I was hoping you would pop in! Amazon Fire, 3rd Generation. 4.5.5.1
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Ok - you'll be using Safestrap v4 and have a choice of Fire Nexus ROM or CM11. Both are KitKat based, stable and feature complete. Choice boils down to personal preference.

Suggest starting with this post (seems popular) for an outline of the process and then skim the linked treads (above) along with this one to fill in the blanks.

You can not unlock the bootloader or use TWRP so disregard associated references. Safestrap v4 emulates TWRP but is not a true recovery. Pay close attention to directions/cautions and you'll be fine.

I have intentionally not provided a step-by-step as you'll benefit from bit of reading and be less likely to make a potentially fatal error. Ask questions if unsure.

Good luck.
[Kindle Fire HDX 7" & 8.9" Android Development] sandman512:
Davey,

Thanks , will be trying this in a little while. Any recommendations for one ROM over the other? Also, to be honest and if you have time, I wouldn't mind steps by steps or what order to do it in. Once again, thanks Davey, glad you piped in.

EDIT: Which GAPPS package should I install? Also, how I survive OTA updates... Thanks.
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
OTAs are irrelevant once you have flash a custom rom (overwrites FireOS where the OTA components lives). No preference on ROMs; Nexus is generic Android where CM is dressed up a bit with common tweaks. Can't go wrong with either.
[Kindle Fire HDX 7" & 8.9" Android Development] Clarke33:
Dirty flash didn't work out for me. I wiped cache and dalvik, flashed, then wiped again but after boot up when I got the pop ups, I didn't have enough time to get into apps in order to clear data before it would reboot. It kept rebooting about every 10 to 15 seconds.
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Sorry for the negative experience. Options:

- restore backup (you created one, right?)

- clean flash fire Nexus ROM (you'll have to reload apps/data - ugh)

- dirty flash HDX Nexus 4.0.5 (to get back to where you were w/o reloading apps/data)

- once ROM is working flash the latest Open GAaps nano build (here)
[Kindle Fire HDX 7" & 8.9" Android Development] Clarke33:
Yeah, I restored my backup and I think I'll make sure everything is backed up in Titanium Backup then do a clean flash.

---------- Post added at 09:03 PM ---------- Previous post was at 08:56 PM ----------

One quick question, on the nano Gaps download which platform do I check? Arm?
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Yes - ARM.

Titanium is great but do make a nandroid backup in TWRP and save it off-device as it offers the best chance for a comprehensive restore should things go wrong. Two backups from completely different tools isn't a bad thing either.
[Kindle Fire HDX 7" & 8.9" Android Development] Clarke33:
OK, will do. Thanks

Im having problems when transferring files between tablet and linux laptop (mtp).

Trying to copy movie from laptop, transfer hangs at the beginning eg. 120kb and after 1min. it fails. Tried few linux distros, the same result. Other phones and tablets work fine.
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Assuming via USB tether as you didn't specify. Never had this problem on Nexus v4.0.5 (native install; not using Safestrap) and moved a number of multi-GB files. Might try a different USB cable and avoid any hubs or USB3 ports. I realize this seems elementary (especially since other devices work OK) but it's amazing how many times a different cable or port fixes this type of problem.

FWIW - there is a newer Nexus build (look in original development thread) by the same dev that can be dirty flashed over v4.0.5. Might prove a quick fixed and you'll be back on a supported version of Nexus.
[Kindle Fire HDX 7" & 8.9" Android Development] mt12345:
I specified mtp which means usb.

Tried three of them.

what's wrong with usb3?

I dont think I can dirty flash as I use safestrap.
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Sorry, missed the MTP part. Also correct on dirty flash w/Safestrap. Might have to upgrade FireOS as well; see prerequisites. Some USB3 ports/drivers don't communicate well with USB2. Not a oddball situation. A little Googling will surface many weird cases. Suggestion was just that. If you are confident with the USB3/USB2/HDX interface go with it. FWIW USB3 on my primary host works fine with 3rd gen Thors.
[Kindle Fire HDX 7" & 8.9" Android Development] mt12345:
Rebooted both devices tried another cable finally it worked. Looks like permission issue because copying tablet>laptop works just fine. Anyway dirty flashed new build, got 'process xxxx stopped working' pop up so clean flashed (see other thread).

Quick ques Google Playstore keeps not wanting to run due to crashing.

I rolled back app a few times by uninstall updates even even tired uninstall reinstall the app.

How should I fix this problem?
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
This ROM has been discontinued. See below for successor. GAaps and SuperSU are built-in which should (indirectly) resolve your issue. Seamless cutover if flashing via twrp (unlocked bootloader). Might have a few preparatory "to-dos" if using Safestrap.

Assume you installed this rom as an alternative to Fire Nexus HDX due to 4.5.2 (vs 4.5.5.1) FireOS base prior to installing Safestrap v4. Thoughts:

- must be a 'clean' flash (wipe system/data/dalvik/cache)

- be sure to use the older GAaps package linked in the OP which will auto update to the current version over the course of several days

- if problem persists you make have to flash a Safestrap compatible version of FireOS to the stock slot prior to flashing this ROM

- as with all Safestrap actions be sure to protect yourself by ALWAYS keeping a known good/bootable rom zip in a safe location on device (suggest the root of sdcard directory) and NEVER perform a 'factory reset' from outside the Safestrap environment
[Kindle Fire HDX 7" & 8.9" Android Development] skeptic1007:

Besides that, great work dude!
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
...because you ignored well published guidance and created/installed Nexus in a secondary Safestrap slot. Delete the slot and flash Nexus (and all other Safestrap compatible HDX roms) to the STOCK slot.

Might have noticed the '[DISCONTINUED]’ tag in the thread title. Yeah, there is a newer version and this ain't it. Look here: http://xdaforums.com/kindle-fire-hdx/orig-development/rom-fire-nexus-rom-ktu84q-t3322931

Hi there!

I just installed it and I´m wondering how long does the first boot take?
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Anything over 5 min signals a problem. Did you perform a factory reset from the Safestrap/TWRP wipe menu prior to flashing? Also, why are you flashing this ROM which is clearly marked "DISCONTINUED" in the thread title? There are better options that are Safestrap compatible and an even wider choice of ROMs if you unlocked the bootloader.

Thanks, I took another ROM (the new Nexus) and everything´s ok!

Thanks.
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Support for this ROM is discontinued. The direct replacement can be found here. Wipe the system/dalvik/cache partitions before flashing. The data partition containing your apps/data can be retained. The Play Store should work fine after the ROM is updated. Might take a few reboots for everything to stabilize.

Hi!

I currently have a Kindle HDX 7 3rd gen Thor with this particular rom already installed as a gift. It has Twrp 2.8.6.0 and the latest Supersu installed. I do not want this rom anymore so I tried to reflash it with the amazon latest update to get it back to stock, using twrp. The flash fails with E: error executing updater binary in zip '/sdcard/Update.zip stating that this package is for "thor" products; this is a cm_thor". Where can I find the correct package for my kindle? I am no longer interested in roms and would like to just use the kindle as stock like using amazon services. Can I be pointed in the right direction to achieve this?
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
You can't flash Amazon binaries as you discovered. Flash the latest version of FireOS from this thread. Your device won't be entirely stock (not possible) but close enough.
[Kindle Fire HDX 7" & 8.9" Android Development] Goonswoon:
Ok..thanks! Just to make sure I know what I am doing, I use the same method as I did using the amazon binary but substitute for the thor file in that thread? I actually read through some of that thread and there are reports of it not working. Does that thread contain the latest stable? I'm just a little nervous going forward. I'd rather have an unwanted rom than a bricked kindle.
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Give me a day. I want to browse that thread to see if any recent/unusual risks have been identified.
[Kindle Fire HDX 7" & 8.9" Android Development] Goonswoon:
Sure thing. I didn't know going back to stock was going to be this tricky. Although this was meant as a gift being rooted and all, I did not know it also meant giving up the amazon services. I suppose that is the price of gamble. I will await your reply. Please let me know what your findings are. Thank you.
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Be aware you do not have to sacrifice most Amazon Services on a custom ROM. What functions/services do you use? Shopping, Kindle books, music, video?
[Kindle Fire HDX 7" & 8.9" Android Development] Goonswoon:
Yes. Those services are what I would like to use. Is that possible with a custom rom?
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Sorry to for the delay; on the road responding from my mobile (awkward). Yes, Amazon's Underground app provides 95% of the capability of similar apps bundled with FireOS. Among the few exceptions are Kindle book sharing and the lending library. The standard Kindle book reader/library, music, video, app store and general shopping are fully supported.

You will need to upgrade Fire Nexus to a supported version and install the Underground app. Both are relatively easy to do. You can sample the latter via the linked download (or search for it if not comfortable clicking a random link). Not sure everything will work on the build of Nexus currently on your device.

[Kindle Fire HDX 7" & 8.9" Android Development] Goonswoon:
Ok. I will need to update this current rom to use the app? Also so I am clear, the modified stock rom option is a no go?
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
I don't see anything risky around attempting to flash a modified FireOS 4.5.5 image from here. There are some reports of it not working (refusing to install) but nothing suggesting bad outcomes. Be sure to grab the Thor build (for 7" model).

To upgrade Nexus flash the latest image from this thread. If you prefer to retain existing apps/data on the device do not perform a 'factory rest' as advised in the OP. Only wipe the 'system' partition (not 'data') then flash Nexus. Should boot up fine.

As a precaution you should unlock the bootloader BEFORE flashing a new ROM which will facilitate recovery efforts should something go wrong (unlikely, but better prepared than sorry). Since TWRP is installed/working the device already has a vulnerable bootloader. Simply follow steps #1 and #3 from this post (skip step #2). Bootloader unlocking poses no risk to your device. It will either work or not. Step #2 is the only risky element; that's already been done.

Post back once Nexus has been updated (if you choose that path). I can then help you through the Amazon Underground install. Feel free to ask questions as needed.
[Kindle Fire HDX 7" & 8.9" Android Development] Goonswoon:
Ok. I installed the modified thor stock rom. Everything went smoothly no problems....except the device will not register so none of the apps will work. I tried looking around to see what the issue could be and it seems that the serial number is all zeros? What happened to the serial number and how do I get it to show up?
[Kindle Fire HDX 7" & 8.9" Android Development] Samson Lau:
This workable. Thanks for your help.
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Well that's not good. I've heard about devices that won't register with Amazon but never persued it further. At this juncture my recommendation is to forego FireOS and install the previously linked version of Fire Nexus.
[Kindle Fire HDX 7" & 8.9" Android Development] Goonswoon:
Oh wow..ok. I am sort of confused why the serial wouldn't show up on my kindle? It is a modified rom that has worked for many others. I have also searched the forum and have not found another case like it using this rom. It leads me to believe something may have went on error somewhere while flashing? I have no idea how to trouble shoot further and I also have run out of steam with this kindle. I am not new to flashing roms but, it seems the process to get this working is overkill. I am thinking I should just sell this kindle and buy a regular one. Thanks anyway for all of your help.
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Understand your frustrations. Flashing Fire Nexus only takes a few minutes and will liberate the device from FireOS v4. Amazon Underground will grant access to Amazon's ecosystem. Don't think you will be disappointed.

Serial number is hard coded into the device. No idea why FireOS is not finding/exposing it.
[Kindle Fire HDX 7" & 8.9" Android Development] Goonswoon:
EDIT: I just went ahead and flashed the kindle back to a back up of the nexus rom that was originally on the kindle so it is functional as an android tablet once again. I really wanted the modified rom to work but it cannot find the serial at all.

I downloaded the underground app just to take a look before I put this kindle out to pasture and it is ok. It does not give the Fire os interface that I was looking for. It is just an app to get into the store, videos or what ever. I appreciate you providing it for me, though.

I think it's best that I just go buy a regular one. I also have an amazon echo, fire stick and I plan on getting Amazon Prime shortly. I do not think an android infused kindle will compliment this set up. Did I mention that my phone is an android making this kindle kind of redundant in the long run.

On another note, I see how you are all around these threads helping out everyone who asks and while I think that is so awesome of you, why doesn't anyone else try to help others....like the developers of these roms? Do they just churn them out and leave you to help test and work out the bugs? I do not mean this in a bad way towards the developers but surely you need help with the loads of inquires?
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
I understand. FireOS is not evil has its place in an Amazon centric ecosystem. We use many Amazon products/services and have a couple Amazon branded devices that remain fully stock. Most run custom ROMs and interface well with Amazon services.

If you do opt for a new tablet suggest going with a 5th or 6th gen device that runs FireOS v5 or above. 3rd/4th gen devices are dated and likely will not support the latest Amazon offerings (eg: Alexia). 3rd gen HDX models are somewhat unique as they were positioned as affordable premium devices and remain competitive in that segment three years later. Amazing.

The volunteer HDX developers (one primary) have unselfishly gifted the HDX community with their time and talents without compensation other than the occasional thanks posted by XDA contributors. Life balance is hard.
[Kindle Fire HDX 7" & 8.9" Android Development] Goonswoon:
I know it is extremely hard for the developers here. I in no way meant my reply to be ungrateful or bashing against them at all. I was just looking at it from a side glance point of view recognizing all of your hard work also.

So.........1 last time just to make sure I did everything I was supposed to with flashing this rom. What are the actual steps I am required to take to flash the modified stock os for my Kindle HDX 7in Thor? Can you list them? I want to see if by chance I could have made a mistake that caused the serial to not be recognized. I have a backup of the nexus rom to use already stored in TWRP so I am not worried about losing any data or settings so I can at least leave it functional if the reflash still wont produce the serial. It was very easy for me to restore using this backup. Thanks so much for your help.
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Since you are not concerned about existing data:

- from TWRP Advanced menu wipe System/Data/Dalvik/Cache partitions

- from TWRP Install menu flash modified FireOS 4.5.5 ROM

That's it. If FireOS can not 'see' the serial number the device may have been black listed by Amazon and/or altered at the hardware level before you acquired it.

Remote possibility the OTA block is creating an issue. You can remove it following the guidance in this and this post. If successful the device will try to download an OTA update but will not be able to apply it as it has dependencies on stock recovery which has been replaced by a custom recovery (TWRP).
[Kindle Fire HDX 7" & 8.9" Android Development] Goonswoon:
So a serial number of zeros indicate a blacklisted kindle? What part has been removed to alter the serial? Then kindle does not appear to have been opened before at all. It looks to be new besides the android os being installed.

I never did an advanced wipe with the initial Fire os flash. I just did the factory wipe is there a difference?
