Hi there, does LTE come up if you reboot a second time?

I have noticed that especially from cold boot LTE doesn't come up, but a subsequent reboot seems to make it work.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] cl-i:
LTE is always a slow starter on our HDX.

Switching Airplane Mode off and on seems to have an effect on the LTE modem if it's not working.

In fact I use "Airplane off" to assure, the LTE is not consuming power, because 99,5 % of the time I am in WIFI range with the tablet.

With the April version, I often received a message "SIM card removed, please reboot". In fact at that time there was no SIM card inserted. So another reason for Airplane off.

My first boot with the May version made LTE work, but I took quite some time.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Max.mk:
No, nothing helps.

Actually, what I really need is the GPS function. Till now I used the device with CM-11 as a navigator in my car.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Surprised that worked given the poky hardware refresh rate (1-2 sec) on GPS equiped devices. Suppose it would be ok in some areas; complete non-starter in high density situations. I also experienced random freezes lasting up to 30 sec. Believe that was on Fire Nexus...been a long time.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] cl-i:
GPS and compass are not working with 7.1

I installed the app "gps-status" on 7.1 and on CyanogenMod 11.

On 11, everything is fine. On 7.1, nothing works. The app reports : "There is no GPS" !!

I would switch back to 11 in this case (GPS required), but to the new LineageOs Version, ggow builded.

[Kindle Fire HDX 7" & 8.9" Original Android Develop] urigg:
Never seen GPS with any custom rom working. Compass seems to be fine though.

One more thing with Apollo-LTE:

Without an installed SIM card, my HDX is not going to deep sleep, running at lowest CPU speed all the time, with bad standby time of course. Easiest workaround: Go to flight mode and enable wifi manually. (Same for all roms since last year, never reported that, sorry)

I did a test with SIM card, and got it to connect 3G, but had to do a manual reset of the APN list to get it running. Does properly deep-sleep with SIM card.

Well known issues:

Wifi doesnt switch off properly in standby (if set to do so). To revive it, either toggle flight mode, or: Go to wifi settings and switch it on-off-on. Note that only the fullscreen wifi page shows it as off, all other displays show it as on and fail to switch it off. Wifi also stays on and working as long as power is connected.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Max.mk:
Is it documented? Yes, I've seen that many are not satisfied withe the GPS. It is not perfect, but for me that worked ok.

I tried many custom Roms, but never seen compass working. Also in the cases when LTE and GPS worked.

Yes, I'll do that. That is also a good rom. The only thing is that some apps do not run with older Android versions anymore.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Not sure what you are asking on the documentation front. Observation of the coordinate stream reveals the refresh rate to be as described.

Never seen the compass work but didn't go looking for it either. I have long since dumped my LTE equipped HDX preferring the 7" model for personal use case.

---------- Post added at 11:40 AM ---------- Previous post was at 11:29 AM ----------

I have also observed increased idle drain rates (approaching 1%/hr) on recent builds without flight mode engaged. All indications are a kernel wake lock (msm_hsic_host) which haunted Nexus 4 devices in their day. Haven't fiddled with just toggling the WiFi radio to mitigate as the former meets my needs. Have an Edge routine that handles the on/off task automatically on power cycle. Opted not to report until now as I doubt [MENTION=5749760]ggow[/MENTION] has the time/energy to track it down. Just happy to see occasional updates for this aging gizmo.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] ggow:
I will look into this, I am in the midst of a massive update for this rom, testing all changes as I go (at the cost of not having enough time for the mediatek devices) with a view to moving forward. I'm hoping to get all the roms onto a single version for better maintenance with the little time available.

Any other debug information you can provide would be appreciated. I remember this issue from android 4.2.2.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] cl-i:
.. if you need a beta-tester, PM me.

I have 2 APOLLO and 3 THOR.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
No further technical info beyond what has been shared. In airplane mode average idle drain drops to a respectable 0.12-0.15%/hr. Reenabling the WiFi radio spikes wake time and corresponding drain with little/no corresponding network traffic. Previously mentioned kernel wakelock appears to be the culprit or (more likely) a symptom of root cause. Me thinks the WiFi radio is not returning to a low power state after idle timer expiration which is usually set to 180 seconds.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] urigg:
No additional hints here either. In my default config (mobile no sim card in flight mode, wifi off in standby, BT off) I'm getting the usual impressive standby times, 1-2 weeks with light usage. My quick test with mobile on + sim card had the device in deep sleep, so I assume this is just a no-sim-card issue.

The rest is just old news: To get wifi back from standby, toggle it on-off-on, or to get BT paired, make sure the device is busy, especially BT if you can. Suspecting some power management issue while pairing.

If I can help somehow (Apollo LTE), let me know.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] cl-i:
More Wifi : To reproduce the automatic reconnect failure, you simpy have to restart your WIFI router (even if your tablet is in airplane mode at this stage). The "new" wifi will not be reconnected.

Even after doing it manually once, the automatic is lost until you restart the tablet.

Because I'm powering down my router at night, im very familiar with this bug.

Unfortunately going to Airplane mode and back is often used while playing real racing 3.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
WiFi issues are intermittent for the HDX I'm currently using. For the past several weeks device has reliably reconnected coming out of airplane mode regardless of AP. Spontaneous disconnects in mixed 2.4/5 GHz environments also seem less frequent. BT pairing is shot with exception to a few input devices which I use to keep the device busy. I have certainly experienced the other WiFi issues at various times. FWIW - typically reboot every 3-4 days; router stays up 7x24.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] brainwash123:
I currently have AospExtended (7.1.2 since ~2018). The issues I'm having: the tablet is randomly slow to react, wifi reconnection (for example due to "turn off wifi during sleep") works 20% of the time, GMS randomly causes battery drain until the tablet is restarted.

Does it make sense to switch to this ROM? Are there any alternatives? I will try it out anyway, but not expecting any miracles.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] void555:
Are you sure this still happens with 20200528? This build includes my fix for broken Wi-Fi auto reconnects. It still sometimes disconnects (once in several hours in my environment) but reconnects automatically.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Soulreaver1993:
That was a great improvement!
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
While I enjoyed my time with AEX (10 months) there were several annoying behaviors that pushed me back to LOS. WiFi disconnect/reconnect was not one of them. That said, LOS is the only HDX ROM that receives regular maintenance. It makes sense to switch IMO if you are currently dissatisfied with AEX.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] brainwash123:
I've switched to LOS last night, it's smoother than AEX and reconnects faster. Previously, I had to manually go into the settings and disable/enable the WiFi, it was not reconnecting by just pressing the icon in the status bar. It reconnects pretty quickly once out of standby (a few seconds) but I'm having an issue I did not have before: random disconnects. I guess it's fine for now, as I don't use it for online games. I'm on the latest build (20 May).
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Random disconnects on HDX LOS occur most frequently in mixed signal environments where 2.4 GHz and 5 GHz signals eminate from the same AP. Try disabling one or the other to see if it improves your situation
[Kindle Fire HDX 7" & 8.9" Original Android Develop] cl-i:
WIFI Reconnect fails 100% after router-reboot and 10 times a day for me.

Environment: Channel 11 on 2,4 Ghz, 5 GHZ disabled. Asus RT-AC 86U with Merlin Firmware.

check out ebay for a used one. Or one with a broken display, and combine it with your dead one.

The 8.9 Apollo is even better if you need a tablet for Browsing, but be aware that there is also a non compatible version (4th generation).

[Kindle Fire HDX 7" & 8.9" Original Android Develop] tb314:
I am facing issues with this version: Right after power-on, the device hangs displaying "fastboot". Reverting to the previous version from May did work fine. Am I the only one with this issue? I am running on Thor and could provide logs (which ones?).
[Kindle Fire HDX 7" & 8.9" Original Android Develop] draxie:
Chances are that

(a) the current version skipped fake-signing the boot image AND

(b) your Thor has a locked bootloader.

Since the device ends up in 'fastboot' anyway, you could check with this command:

fastboot -i 0x1949 oem idme \?

Depending on your OS you may or may not need to pass the vendorID (i.e. keep/omit '-i 0x1949')

and/or escape the questionmark (i.e. use '?' instead of '\?').

UPDATE: I've just downloaded 'lineage-14.1-20200704-UNOFFICIAL-thor.zip', extracted 'boot.img',

and it appears to be "signed". So, the issue must be something different...

Any chance that you may have also installed Magisk (which rebuils the boot image,

but has no idea about any Kindle HDX fake-signing weirdness)?
[Kindle Fire HDX 7" & 8.9" Original Android Develop] cl-i:
Perhaps your ROM was broken on download ?

I installed the ROM on my Apollo, doing it "dirty" to observe my other apps.

Well, the ROM starts up, but it doesn't feel good. It seems v e r y slow.

Starting Apps (play store for example) causes a long pause before all elements are loaded and displayed.

[Kindle Fire HDX 7" & 8.9" Original Android Develop] ggow:
This is very strange, as mentioned by draxie - the only reason I could think of for this is that Magisk was installed. Even with an unlocked bootloader I don't think Magisk works. Someone correct me if I'm wrong.

I usually use the build in root option.

As for logs, if you're tablet is hanging and going back to fastboot then I don't know which logs might be relevant. Normally if the tablet hangs and you get to recovery then you can usually pull /proc/last_kmsg.

First of all: Thanks a lot for all your efforts! I really did not expect those fast replies and indeed the issue was resolved.

For me, the problem was ineed Magisk. I just verified that on my device version 07-05-2020 does not work with Magisk (fastboot issue) but boots normally without it. The May Version ran fine with Magisk installed though.

For me, this raises the question, which root app you recommended for this version?

Concerning my device, I am running TWRP 3.2.3-1. Which output of

fastboot -i 0x1949 oem idme \?

are you interested in? It yields a final "OKAY", but I can provide you with more information.

Thanks for this great ROM! I really appreciate all your hard work!

Just wanted to ask if any of you guys here have ever had a "Headphone loud ticking noise"-problem with your HDX as i'm describing im my post here: https://xdaforums.com/kindle-fire-hdx/help/kindle-fire-hdx-8-9-headphone-loud-t4124795

I'm asking here because this thread seems a lot more active than the troubleshooting area and because i'm using LineageOS-14.1.

I had the same problem on some AOSP Kitkat as well though. So i'm pretty sure it's not the OS's fault.

Maybe i'll open the device and have a look if i can find anything super obvious with the audio jack.

Just a couple of questions about the latest update for clarification:

1. Is the Bluetooth now working properly all the time? I have the May build, and I was only able to get Bluetooth headphones to pair a couple of times.

2. Is the definitive guidance for installing the latest update to uninstall Magisk?

3. Can we dirty flash? Just asking because you said a lot has changed since previous build, and a lot of times that means a clean flash is needed.

Dear Mates, if anybody finds a solution to get Clash of Clans working

reliably

with this ROM (Lineage OS 14.1 from ggow) on this device (Thor), I will DONATE a Fire HDX Thor 7'' device.

I will send it for free to the first individual who can post or PM a detailed solution for getting Clash of Clans running with this ROM.

The conditions are, that it has been tested by that person, that installation of Clash of Clans and updates are running through google play store and that I can get it running using the proposed solution.

However, the device will be used, and battery status will not be good, since all seven devices I have are in use. But it will be rooted, have TWRP and this 14.1 ROM running. I will send it for free, worldwide, just need the address via PM.

I hope this is not against the rules...

EDIT: Maybe its better to send PM, so this thread is not blown up. If there is a solution, it will be posted.

Nothing more and nothing less, I know it's not a big reward, but I will offer one of my devices, if somebody gets Clash of Clans running on this 14.1 ROM.
