Unless your HDX is LTE enabled would still need an accompanying telecommunications device (phone) registered for voice/text service with most GSM carriers. Even with imbedded LTE the functionality would likely be far from satisfactory. I use my WiFi only HDX as a secondary device with a US based carrier via a robust, multifunction messaging app. In that capacity it works well for synced SMS/MMS and the occasional voice call when I'm too lazy to grab my phone.

I have a cellphone with a gsm lte sim with a calls,data and txting plan.

All I want to know is will I be able to take the sim out, put it in an LTE HDX with this ROM installed and be able to send/receive sms and make/receive calls using the gsm lte simcard, no calls over wifi or syncing this n that? If not this rom any of the others?
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
No - at least with the suite of custom roms currently available. No native voice capability; not sure about FireOS (check w/Amazon). Data may work but likely won't engage as smoothly as on other devices. Text is dependent on the capabilities of the (your) messaging app.

Does Nexus ROM or CM11 support F2FS? If not, will it support in future?

Not that I'm aware of. Also doubt these older KitKat based roms will see significant enhancements given they are now 3 gens back.

For some reason videos play in reversed landscape and Dead Space mobile does too. I'm sure some other older games might do it too but so far videos in dolphin and mx player are upside down I can change it to reversed in mx so it's like normal but is there some way I can fix this? Using an xposed module? Editing something? Also why is it doing it?

Oh no please help :( I caused it to get stuck in a bootload by overwriting the libc.so file in system/lib what do I do to fix?

If you can not get Safestrap Recovery to come up little can be done to revive the device. There is no way to reload FireOS or repair whatever you did if Safestrap is not functional.

As previously noted if you can't get into Safestrap and the stock rom (Nexus in your case) is non-functional the device is not recoverable.

Low volume problem

I have had very low sound volume (chrome, netflix, etc) with this ROM installed. When I first flashed this ROM and noticed it, I got volume booster goodev from the Google store. Unlike some of the other apps, this very noticeably cranked up the volume. I don't know what happened, no updates or anything, but it no longer works. I'm trying to find something else, but not much luck. Nothing in x-posed works on 4.4, and I don't see anything I can change in kernel adiutor. Maybe can use root to boost sound settings, but not sure what to change?

Or u could just install and use viper4android that way you could boost the output gain and have full control over bass and clarity across all applications not just music
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Raymodjp:
I didn't write that very well. I have xposed, there just aren't any downloads that I can find that increase my volume, they just tweak it. I have also tried quite a few apps, including eq and volume boost apps, but they aren't helping now. Not sure about viper4android. No English translation yet, and it wants to install a driver? I was hoping to tweak the sound myself. I found a suggestion to modify a file in device/etc/sound, but the folder and file don't exist.

Edit: after messing around uninstalling, rebooting and reinstalling the volume boost, I have it working with everything but chrome. Guess it is time for a new browser.

Edit 2: tried several browsers, all have same low volume level. Sound boost had fixed this on chrome until about 2 or 3 days ago, I didn't intentionally change anything...
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
I have not experienced any significant audio issues with this rom. I use Opera (plus a few others) but I suspect it would behave the same as Chrome as both are Chromium based.

Flashing Dolby ATMOS brings a significant improvement in audio quality including a notable boost in volume with voice enhancement enabled. There are several ways to obtain the package; sample links below:

It is in english u probably just saw the unofficial version that's made by a Chinese developer in the play store, the official one from the viper4android blog is in like 7 different languages plus english. I've had it on all my rooted devices, people say dolby atmos is good but I've never used it. The driver installs in less than a second and can be uninstalled any time. It has multiple ways that could increase volume changing the playback gain, the master output gain, and u can turn on the extra loud setting if you're using it through the speakers

[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Thanks for sharing; glad you were able to revive your hdx which likely (almost certainly) had a vulnerable bootloader as evidenced by the ability to subsequently install twrp. Typically not the case for those using Safestrap v4 which has a FireOS 4.5.x prerequisite. There is no evidence the bootloader can be unlocked post 3.2.6 reinforced by the widely acknowledged disclaimer at the top of the thread you linked. That said, Safestrap v4 can be installed on a device with a previously unlocked bootloader which is probably what happened on your hdx. In that case recovery is possible.

[Kindle Fire HDX 7" & 8.9" Original Android Develop] CocoBun:
The latest was on it before I put fire nexus on it which will overcomplicate things and maybe I'm screwed but if all fails I'll buy another one and put fire nexus on it but I won't do what I did that caused a bootloop overwriting system files using es file explorer while it was on was a dumbass move I should have gone through safestrap to do it that was what I was supposed to do. That's all it takes to ruin a device something simply stupid like that. The sad thing is that I already knew better but I still did it :(

---------- Post added at 01:18 AM ---------- Previous post was at 01:14 AM ----------

I wanted to put twrp but I didn't think I could cause of the bootloader version. Does updating to a new version of fireos update the bootloader too? I got mine way back in November of 2013 on my 15 birthday so if it doesn't update the bootloader too then it would have an older version on it that would let it be unlocked so twrp could be installed I don't know much about bootloaders I choose not to fool with them and it's better not to
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Bootloader/kernel revisions are included with most OTA updates. If Safestrap v4 was installed (recall FireOS 4 prerequisite) the bootloader is not vulnerable which itself is a prerequisite for flashing twrp.

The various component combinations are somewhat complicated but also well understood. The previous poster, while trying to be helpful, does not appear to be knowledgeable on the nuances of this device.

While you made an avoidable error trying to flash twrp (should have consulted the forums first) the outcome would not have been fatal if Amazon had included a mechanism for reinstalling FireOS from the stock recovery menu.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] CocoBun:
I never attempted to flash twrp I read about the bootloader prerequisite and I wasn't sure so I left it locked and installed safestrap instead then made a backup of the system and data of fireos and flashed fire nexus and had that on it for a couple days. If safestrap was able to start in a bootloop then I would have already had it fixed. It really doesn't serve it's purpose as a recovery because of that. I'm not an idiot I did my research first

---------- Post added at 01:30 PM ---------- Previous post was at 01:27 PM ----------

And yeah reboot or factory reset makes for a useless recovery, Amazon sucks at software stuff the device itself is pretty good could've had more ram and an sd card slot but it has a good design and better resolution than most tablets when it was out

Sorry 'bout that; lost track of the detail in all the back & forth. Doesn't change the prognosis but obviously you had done your homework and didn't make an ignorant flash gaff. Safestrap (any version) was never purported to be a full fledged recovery environment but it's easy to think of it that way given the twrp like appearance.

To fix this issue I can truely recommend the following Viper4Android package:

No strange noise issues anymore and really good audio quality.

I haven't had much time recently to look into any of this. But will once I do.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Raymodjp:
I don't know. It's probably me, but I am going to blame this refurbished tablet. I still haven't figured out the 5 GHz wifi other than that a signal still shows up VERY intermittently. Now the sound booster that worked still works for everything but various browsers. I went back to Fire OS 4.5.2 and volume was good, flashed Fire Nexus and browser volume about 1\2 as loud at max. Flashed old Nexus 4.0.5, then cm 11, also low volume. I tried suggested Adobe, nothing, and ran into BusyBox issue others have had when installing viper. Tried +volume with audio_effects, but still nothing. Looking at various system files, but no luck yet.

The hard part is that issues like this are obviously not the norm, so hard to pin it down. I love the Android experience, so I am going to keep trying. Thanks for the suggestions.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] ggow:
- The audio issue is on my list of jobs, if you figure anything out let me know.

- Did FireOS prove any better at showing 5 GHz networks?
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Raymodjp:
I haven't found any real solutions for the audio issue. In CM 11 I found I could change the rx5 digital volume level from 84 to 92 and it helped, but some volumes still low and some too high and distorted. So not a fix, but might help my issue. I am in fireOS now, so just getting ready to flash fire nexus again and poke around in the mixer_path.xml file.

FireOS didn't find the 5ghz at setup the second time I flashed it, but otherwise it has found and held the signals for an hour or 2 both times. Fire Nexus also found the 5ghz at setup, but it disappeared after I let the tablet sleep. There doesn't seem to be any one reason for signal loss. Once I lose it, I might not see it again for several days even after reboots.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
On rare occasions I found a full power cycle (off/on) fixed wonky radio issues on this device. Been awhile since that happened and I can't be 100% sure a power cycle did the trick. Easy enough to try if 5Ghz goes missing again.

how do you disable mobile network? It seems I can't find a button to turn it off except of putting tablet in airplane mode
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
You can't but there is no resource drain despite false reporting by some battery apps. If using the old/discontinued build a mobile network icon will remain in the status bar and can not be removed. The latest build only displays a mobile icon (and enables related controls) if the device supports 3G/LTE communications.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] mzk1:
just got back home from work and checked the battery usage since yesterday's night and it showed that cell standby used 63% of all the charge used. I downloaded the latest rom (suppose to be) from the link in the head of this topic. And yes the cell network icon stays even after I disable the data usage. Just to compare WiFi used only 7% according to the battery monitoring tool, screen - 14%, google play services - 9%. Oh, yes my tablet has cellular. So the question remains I guess. I can put it in the airplane mode and turn on WiFi only, but it'd be nicer if you could just disable cellular.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Thoughts:

- as previously noted battery apps falsely report high usage of the cell/mobile network components on this device

- as I recall you were unable to update to 4.5.5.1 so still running 4.5.2 kernel

- this rom is only certified with 4.5.5.1 kernel (see here); could come into play if excess drain from mobile components is confirmed

- understand your request but to the best of my knowledge this rom does not offer an on/off toggle via UI (can't check as all my HDXs are WiFi only)

- you might have better luck with an Xposed module like Smart Network which can conditionally toggle various radios

[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Nexus is close to AOSP (pure no-frills Android) while CM-11 contains various UI customizations popular with some communities. Really need to try them both to understand the differences. Both are stable, full featured and mature.

Hello all - I just loaded this ROM on my HDX 7 3rd Gen this week. Everything's great and working, except I'm getting a strange error when I'm inside the Amazon App store app. Most links from the main menu (Store Home, New releases, Top Charts, etc) give me an error page within the app that says, "Looking for Something? We're sorry, the Web address you entered is not a functioning page on our site. Please double-check the URL for typos and other errors. Or go to our home page." Then there's a French translation below it (randomly - why French??) The only thing I can reach is the "My apps" screen, and I am able to download apps from the cloud. Also, trying to "buy" more items inside an Underground App that I downloaded leads me to the same error page.

Anyone else experience this?
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Suggest going with Amazon Underground (legit) as it is designed for generic devices/roms. The native Amazon app assumes a FireOS v4 base which is a heavily customized version of kitkat.

That was what I used first, and had the same problem, so I uninstalled and went with the original. Now, I have uninstalled the original and installed Underground - and the same issue is happening. I can reach all the menu items except the "Underground Apps" portion. It's like that whole section has the wrong URL or something.

I loaded this a friend's 8.9" HDX after they were tired of not being able to run the apps and games that their other friends were playing off the Google Play store. Everything went really smooth with apps and installs until Pokemon Go. The app downloaded and installed fine. Chrome downloaded and worked fine to download PokeMod EX right here from XDA (http://xdaforums.com/android/apps-games/app-pokemod-ko-mock-location-suite-t3422620) since they didn't have a cellular model HDX. Installing ModEX as root says it fails, but if you reboot and run it, it's fine and is installed as root if you check in the priv-app directory with a root file browser. The problem is when using it and launching the game, it randomly reboots the tablet.

Could use some help here.

I have Fire HDX 8.9, 4.5.5.1, 3rd generation, 4G/LTE, 16GB and trying to install Nexus Apollo.

So far I did:

1)Install KingRoot and rooted my Fire (confirmed)

2)Install ES File Explorer that I used to change the permissions like this > Root Explorer>Mount R/W>changed permission to RW in: /system and /mnt/sqfs

3)Installed Safestrap 4.0.1 and followed instructions - all good and working

Next step is to install Nexus Apollo but before I proceed I would like to clarify the exact process.

Instructions saying: Transfer that to a safe location on your device, preferably in a folder you create directly under sdcard.

Q: where exactly?

When I plug my Fire to PC I see ONLY Internal Storage on my Fire? So when create Nexus folder and transfer the Nexus Zip file there is that good enough or will it get wipe when I install Nexus on the Stock Slot?

or should I use ES File explorer to create folder in the root and move the Nexus ROM there?

Where and how please.. ??

I am trying to avoid the bellow problems!

It is important this file (or it's successors) remain on your device at all times for emergency recovery. Putting it in the suggested location reduces the chance of accidental removal when wiping the (user) data partition. You can also place the folder directly under root (/) but be aware some file managers and tethers restrict access to high level directories.

Important: Unlike TWRP Safestrap v4.0.1 recovery has no ability to communicate with the outside world. Not by tether, wifi, bluetooth, adb, etc. It is fully isolated environment. If your rom becomes unstable (rare...but it does happen) your only recovery is using a previously created backup or a flashable rom image (as discussed above) resident on the device.

That's exactly my concern - will my Apollo Nexus folder get deleted when I install it Nexus on the Stock Slot. Does it wipe ALL the folders in the Internal Storage?

Can I/ should I move the ApolloNexus folder using ES File Explorer 3.0.5 in to Fire Device directory or Root and will I be able to access it after the wipe.?

Thanks in advance.
