This ROM works great. I could use SIM card and data connection works great, even I can send and receive SMS using AOSP messaging app.

I understand that tab or ROM doesn't have cellular call functionalities. However, when someone calls this number, it rings at remote side and gives false impression. Is it possible to initialize so that calls are disabled. If not, any possibilities to see incoming number?

not sure where to post this so move the post if needed but I am curious if there is way to my HDX 7 to newer OS or is it stuck using this KitKat ROM?
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Absolutely - a vulnerable/unlockable bootloader can be installed on any 3rd gen HDX opening the door to a number of high quality Lollipop, Marshmallow and Nougat based ROMs. The procedure is not hard for those familiar with rooting and working with adb/fastboot. At present the reference material is

disorganized and scattered over several threads. It will take a bit of reading and patience to Wade through the muck. Suggest starting with the following thread as your device (Nexus ROM) is already rooted.

Unfortunately, trying to flash this Rom under twrp on my Apollo HDX I always receive error 7. I have already updated twrp from 3.0 to 3.1 with the same result. Your other Rom (final Nexus) does Install without any issues. What could be the cause of error 7?
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
I know the reason (documented in posts #81-91 in this thread) but don't want to reopen that can or worms on a EOL ROM. Booting this build of TWRP should permit you to install the ROM. No need to permanently install (flash) an older build; simply download to host and launch via 'fastboot boot signed-<device>-twrp-2870.img'.

Sidenote: While this build of Fire Nexus served me well for 15+ months there is zero evidence it is faster/smoother/better than any of the Nougat based ROMs. In fact just the opposite as resource management is far more mature on Android 7.x vs 4.4.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] fabische:
Thanks, Davey126. Excellent help as ever! I am looking for a smooth Kikat Rom because the other Roms lack Sim card support. However, I think I will stay with ggows final Nexus Rom, as his more recent kk fire nexus does not provide any functional advantages, at least from what I can tell. (?)
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Yep - you'll need a KK based ROM for SIM support on this device. Choices are FireOS, Fire Nexus or CM 12.1. KTU84Q is the clear winner IMHO.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] fabische:
Why is fire Nexus KTU84Q in your opinion better than ggows discontinued Nexus ROM? They are both KitKat ROMs and I thought, they are pretty much the same...? Is it worth the hassle changing from Nexus to fire Nexus? Cheers!
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
HDX Nexus (which evolved from Jelly Bean) had a variety of small issues that were ultimately resolved in Fire Nexus. You can continue using whichever you choose. That said, migrating to Fire Nexus is painless and has no downsides.

I just install Fire Nexus, but when i play game, it not as good as on HDX Nexus. So how can I do for better game on Fire Nexus? Thanks bro.

Sorry my English bad.:(
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Performance should be similar on these two EOL KitKat based ROMs. HDX devices in general make a poor gaming platform due to an anemic GPU. That said, there is no performance basis for running an obsolete ROM given there are at least four Nougat ROMs to choose from.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] taquochuy_tb:
So, should i run Nougat for gaming, bro? I feel HDX quite hot when play game Clash royale on Nougat AOSP Extended 7.1.2.

Sorry my English bad
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
It's probably hot because AOSP Extended is tuned for maximum performance. Which is what you want, right?
[Kindle Fire HDX 7" & 8.9" Original Android Develop] taquochuy_tb:
Thanks bro, maybe i still at 4.4.4 and use HDX Nexus or Fire Nexus, HDX Nexus have problem with font in game, but i don't know how fix this.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
If your only interest for this device is game play then the choice of ROM really doesn't matter. If you need support it would be best to be on Marshmallow or above.

Dear Davey126,

as recommended, I have downgraded TWRP to v2.86 in order to install kk. However, trying to flash kk-fire-nexus rom in recovery mode aborts with the message:

E:Error executing updater binary in zip '/sdcard/Download/kk-fire-nexus-rom-apollo-20161017.zip'

I was suspecting a corrupted zip file causing the problem. However, after downloading the zip twice and testing the archive without any errors it is not possible to install the rom without the error message mentioned above.

Any ideas from your side?

Cheers, mate!

---------- Post added at 04:52 AM ---------- Previous post was at 04:15 AM ----------

Wow... Sometimes the cause of strange errors can be amazingly simple:

kk-fire-nexus-rom-apollo-20161017.zip now flashed like a hot knife goes through butter.

Cause: Before flashing the Rom I wiped all partitions except the internal. However, starting the installation without rebooting causes the error messages. If you reboot the device after wiping flashing the rom will work :)

p.s.: if this does not solve similar problems, this video might help. It involves editing the roms zip file

[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Yup - have experienced that weirdness with this device with multiple TWRP builds. I always reboot if wiping more than the customary partitions.

[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Did you read the handful of posts just prior to yours? Downgrade TWRP to v2.8.x.x.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] badcrcs:
I finally got 1-click to work on my hdx thor on Linux Mint 19 booted from a usb drive (my regular Linux laptop doesn't support virtualization). The solution was noted in this thread about adding my account to the vboxusers group, then 1-click worked. I got up to installing the nexus rom outlined in this thread when I was getting Error 7 about can't overwrite newer build. Everyone says to downgrade to 2.86. In the TWRP thread linked it's 2.87 which I think will work, but adb still shows my device is unauthorized. I tried adding my public keys to /adb_keys on my thor but that didn't change anything (restarted thor and adb). I don't have a /data/misc/ directory on my device so I copied the key file there and restarted everything, still no luck. So I said screw it and copied the 2.87 TWRP img to the device manually and used TWRP install->image->recovery to flash the image. It says it works, but when I reboot it's still 3.1.1.1.

I've been working on this for days to get to this point and now I seem to be at yet another hurdle. I can't seem to flash any roms because of the error 7, I can't flash an older TWRP image to flash the nexus rom, and I can't use adb or fastboot because my device is unauthorized. I've read a lot of solutions about the keys and authorized devices but most either don't apply or they didn't work. Any help would save my hdx thor from getting thrown off a bridge.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Need some clarification. In the end of the first paragraph, you stated "So I said screw it and copied the 2.87 TWRP img to the device manually" but later you said "I can't use adb or fastboot because my device is unauthorized". If neither of those are available how were you able to copy the TWRP 2.87 image to your device?

Regardless, if you are able to issue fastboot commands simply boot the 2.87 image vs trying to flash/install it: fastboot boot <twrp.img>.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] badcrcs:
Sorry first time I've used TWRP and adb so I'm not sure if I'm using the correct terminology or doing everything correctly. I've rooted and flashed roms a couple times on older droids (OG moto droids, droid X/X2) but they weren't as complicated as the hdx. I'm by no means a newb with linux, command line, scripts, coding, etc, but I really have very little experience using all the utilities and droid hacks. I meant adb/fastboot don't seem to be able to communicate with my hdx at all because it's unauthorized. I can do "adb devices" and see that, but everything else doesn't seem to work. I was able to copy files to the hdx using windows explorer or linux file manager and 1-click on mint was able to communicate after I got that working in vbox. So I copied the 2.87 image and tried flashing recovery but it didn't seem to do anything. Last night I was able to boot into the bootloader which loaded twrp 2.87 and I flashed the nexus rom successfully. draxie and you guys gave me enough info to figure that out. So now I have it working but draxie was suggesting nexus isn't the best rom to use. What's the best rom I can use that works with bluetooth that I can flash with TWRP? I don't care about games, I just want marshmallow or nougat and most things working and bluetooth so I can use a speaker.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Any of the Nougat based ROMs in the Original Development thread (here) provide a nice experience on HDX devices. However, initial BT pairing will be flaky due to kernel limitations. Once paired BT input/output devices perform well and usually reconnect w/o drama. But it can be a trying experience to get through that first pairing, especially with components that demand a pairing code.

I have AOSPExtended with Android 7.1 installed. Also TWRP and unlocked bootloader.

I've got a bluetooth gadget which I want to use with the tablet. In Android 7.1 I can pair device with tablet but the connection breaks after a minute. I want to try Android 4.4.

I'm trying to install this image but TWRP fails with message:

Can’t install this package over newer build.
Updater process ended with ERROR: 7
Error installing zip-file ‘filename.zip'

I've already wiped all partitions except of internal storage.

What am I doing wrong?

Thanks for the help in advance.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
There are several work-arounds for the error 7 annoyance on HDX image flashes. Perhaps the easiest is to downgrade TWRP to v2.8.7.0 which you can do using Flashify or fastboot commands. Be sure to upgrade to v3.x before installing any Nougat based ROMs.

TIP: Instead of installing a back level version of TWRP simply boot the image from fastboot. Works a treat!
[Kindle Fire HDX 7" & 8.9" Original Android Develop] bobocher:
Thank you.

I've ended up editing installation script and removing check for installed version, that was the first line of the script. ROM was installed successfully via TWRP then. Bluetooth works without interruptions.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Yep - that's my approach as well but is a bit rich for the community that typically dabbles with this gizmo. Nexus KTU84Q is a fine ROM (especially for radio support) if the SDK 20 roots don't get in the way. Enjoy.

Profiles not working

When creating a new user profile, both the Setup UI as well as the launcher force close. This is in contrast to your CM11 for Safestrap 4.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Since flashing B20160228 I have experienced random WiFi issues where wireless communications are blocked after the device emerges from sleep necessitating a soft reboot to restore. Cycling radios is ineffective; device connects but nothing flows. To my knowledge I have not added/changed any apps or settings that impact network communications. I do (and always have) enable the setting that disables WiFi while the device is sleeping. The problem does not occur every time the device emerges from sleep but is frequent enough to be disruptive. Same device was working fine on prior builds of the Fire Nexus ROM and HDX Nexus v4.0.5

Any one else seeing this?

Edit: believe it has been resolved - traceable to a kernel timer tweak (cpu wasn't ramping during preparation for sleep which may have destabilized WiFi radio when power dropped). Need a few days to confirm but likely a self-inflicted wound that only surfaced after flashing latest update.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] sanjonny:
Just wanted to let you know that I flashed onto two HDX devices and most everything is working well. It does take a bit to emerge from wifi when woken up, I would guess if it is in some deep sleep state, it can take about 10 to 15 seconds, but if wifi is not off, everything mostly works great. I clean flashed after factory reset and unlocked bootloaders on both devices and have only niggling minor problems. Mostly restored with titanium.

I do notice that the lock screen has a few weird wakeup issues, but being that everything else I have is on MM, maybe I am forgetting that was an ongoing thing. It sometimes emerges from lock with the wrong screen orientation or old lock, but as soon as unlocked, everything works fine so not a real issue.

Thanks so much and I look forward to any new updates. Made my HDX so much better from the old kindle 3.2.2.whatever I was on. So much faster and better performance

im on Nexus 4.0.5 room flashed on stock slot with Safetrap and no backup, any way to come back fireOS 4.5.2? pls help.

Thanks.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
- delete any secondary slots; only the STOCK slot should remain

- flash a Safestrap compatible build of FireOS v4.5.2 from here

- boot into FireOS and and reinstall Safestrap v4 from here

- use Safestrap app to uninstall Safestrap recovery; then uninstall the Safestrap app

Footnotes:

- you may have to reroot 4.5.2 to uninstall Safestrap v4.

- there is no benefit upgrading to FireOS 4.5.5.1 if you simply plan to reinstall Safestrap and run custom ROMs CM11 or HDX Nexus 4.0.5

- updating to FireOS 4.5.5.1 is recommended (and presumably required) to run Fire Nexus ROM from Safestrap v4
[Kindle Fire HDX 7" & 8.9" Original Android Develop] zxcv888:
I am trying to install this coming from CM11 rom with Safestrap v4.01.. The second post said..

"- Safestrap users should update to official Amazon FireOS 4.5.5.1, KingRoot, Re-install Safestrap then install ROM."

I think that may be why he tried to upgrade to 4.5.5.1.

How would I upgrade to 4.5.5.1 after going back to 4.5.2? Do I try to get OTA?
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Aah - so the intent is to migrate from CM11 to Fire Nexus ROM (different than HDX Nexus v4.0.5) which recommends FireOS 4.5.5.1 as a starting point for binary compatibility. In that case follow the instructions in my previous post to reinstall FireOS 4.5.2 and remove Safestrap recovery. Reboot and check for updates from within FireOS. The 4.5.5.1 update should be offered. If not another tweak may be required to reenable OTA. It should be enabled by default but another poster stated OTA was disabled in the Safestrap compatible build of 4.5.2. Fortunately it is an easy fix; post back if the OTA doesn't work for further instructions.

Nice!

Installed on my Thor yesterday. This is awesome, thanks!

Mine is a WiFi-only device, so I'm unable to report on LTE functionality.

Other than that, everything I've tried appears to work as it should. The only exception is a cosmetic issue when pulling down the control panel: The animation draws the first three rows, then the entire panel is erased briefly, then finally all four rows are drawn. (If there are only three rows to display such as when in airplane mode and "cast screen" isn't an option, it draws perfectly.)

Nice job!
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
If the cosmetic issue proves bothersome try installing Xposed framework and the GravityBox module. That will permit customizing quick settings including number of columns/rows, which icons are displayed, secondary functions (eg: long press), etc. It will also address the redraw issue that you noted. GravityBox has numerous other functions including many that emulate capabilities that later appeared in Lollipop and Marshmallow. It's a great complement to Nexus.

[Kindle Fire HDX 7" & 8.9" Original Android Develop] ggow:
Yes, well known issue on most Amazon devices. This is documented throughout most ROM threads. The solution is to lock the screen in the orientation you want before launching your game.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
The Xposed module App Settings fixes this for virtually all apps that impose (or gravitate toward) a specific screen orientation. Changing the preferred orientation from 'default' to 'normal' works for most apps. Or you can enforce a specific orientation on an app-by-app basis. It's a hidden gem that is especially beneficial on Amazon devices running a custom rom. Last official version targeted KitKit; I believe beta builds work on Lollipop/Marshmallow.

Just switched from FireOS to this ROM. Great work.

If (and I have no intention so far) I want to switch to the CM11 ROM do I have to reinstall FireOS 4.5.5.1 and then use Kingroot/Safestrap again to install CM11 or is there an easier method?

Thank you!
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Given the choices assume you are using Safestrap v4. There is no need to reinstall FireOS when switching ROMs. However, I recommend performing a backup from within Safestrap which can be used to recover your device should something go wrong. You can safely delete the backup once the new rom has been successfully booted. A copy can be saved to a suitable host if desired. This must be done from a functioning rom as Safestrap v4 has no ability to natively communicate with the outside world.

Important Safestrap v4 notes (the vast majority of SS users ignored some/all of this guidance and ultimately screw themselves):

- never perform a 'factory reset' from the stock recovery menu; a brick usually follows

- always keep a flashable rom image/zip (CM11 or Nexus) on the device for emergency recovery; it can not be copied later if your device fails to boot

- all operations should take place in the STOCK slot; avoid creating/using secondary slots

- do not attempt to flash any rom that is not compatible with Safestrap v4; a brick is almost guaranteed

No matter what link I click on say 8.9 hdx? Even if it says that are the links correct because I have the 7-inch one?
