[MENTION=5749760]ggow[/MENTION]: memory seems to be limited to 1,66 GB.

Who consumes the gap to 2 Gb? Graphics or a ram drive.

Any chance to gain more free memory from kernel?

---------- Post added at 05:45 PM ---------- Previous post was at 05:39 PM ----------

Yes of course.

Please try my mod to the build.prop for gaining more memory.

Also your aged ROM is based on ggows kernel I would bet.

In regards to Bluetooth; I don't know when it changed, because I have not messed around with Bluetooth in a while, but it is no longer just flaky. It just plain doesn't work at all. Bluetooth share crashes upon turning Bluetooth on, and goes into a crash loop that requires a restart of the device to stop. I know that this isn't a priority, and I personally don't need Bluetooth support, just wanted to note the current status for me.

Well, perhaps your problem is due to Unitymedia / Vodafone DSL in our region at the moment.

Otherwise I have no idea.

On my tablet I also use KernelAdjutor for controlling the Android LowMemory Killer. I'm running "Medium".

Android itself ('core') along with essential services and drivers. Same as any other device. Any gains thru risky kernel tweaks would be highly incremental.

---------- Post added at 12:44 PM ---------- Previous post was at 12:32 PM ----------

If you are going to tweak LMK go after individual categories vs using a generic slider. One can get very aggressive with single tasking scenerios without impacting device stability. Adding a static swap file (HDX kernel does not support ZRAM) can further reduce RAM usage but will adversely impact performance and may lead to premature NAND failure if excessive swap writes occur.

That said, this is an old device with nortoriously slow RAM and horrible GPU. A cheap burner phone from WalMart will handle most game play better than a HDX. This device is optimized for text, audio and color rendition. Not graphics or high bandwidth operations.

Bricked my HDX 7

I know this might not be the best place to post this, but since there's some recent HDX 7 related activity here, I thought it might generate the most up to date responses. I attempted to root my HDX 7 the other day with Kingroot. It was suggested in the guide I was following. Something very bad happened...I can't even pinpoint what it was, but now the tablet either boots to a grayed out logo or goes it into fastboot, depending on which buttons I use to start it. I've tried all kinds of ways, but can't get it to be recognized as an Amazon device by my Windows 10 PC.

I did find a driver that recognized it as a fastboot device, but I don't know what, or if anything can be done to recover the bootloader or whatever it is that's broken. Please let me know if there's anyway to fix this thing. From what I've been reading, the prospects are pretty grim. Thanks.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Kingroot is crap and a distinct risk on this device as there is no native system recovery capability as you are discovering. The only reasonable hope (given age of device and access to community help) is to use [MENTION=5828306]draxie[/MENTION]'s 1-click utility. If it works you'll score root, TWRP and the ability to install custom ROMs. Downside is a Linux or Mac host is required - no Windows.

Upgrading from 2017 version

Hey guys.

I followed this guide in 2017 - so I have an unlocked bootloader and an older version of Lineage and open GApps.

Do I just need to go into TWRP menu and wipe the data partition, then flash the New April Lineage rom?

EDIT: Took forever to finally boot into the lineage setup screen , but so far so good.

Thanks all, and glad to see this project is still going on.

I wanted to confirm this for my device as well, on the newest Thor build turning on Bluetooth causes a crash loop with the message "Bluetooth Share has Stopped". The only way to stop it is to reboot.

I installed this rom on my kindle.

Two issues, which are probably normal, but i don't know that for sure and it bothers me.

1.) I cannot find Netflix in the Play Store (probably because of root? - i can install it from somewhere else and it works).

2.) Amazon Alexa - I also cannot find it in the Play Store, and on the browser it tells me that the device is incompatible with Alexa. I installed Alexa from somewhere else, but it crashes. I know that's not very helpful, i saw in ADB some messages about that the Alex App expected some library... but I am already back to the original rom for now.

But if there is any solution for this, i would like to come back to this rom.

Its still a nice tablet after all those years.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Reverse-anastomosis:
You can install Netflix from apkmirror or from Aurora store, same with Disney plus and other apps that don't show in the play store.

A quick Google search says Alexa doesn't work well on lineage. I have never tried it, but I suspect that if you want Alexa you will need to stay on stock.

After updating from lineage-14.1-20190920-UNOFFICIAL-thor to lineage-14.1-20200419-UNOFFICIAL-thor, my kindle didn't boot anymore but hang on the "Kindle"-logo when booting.

I installed it using TWRP and clearing cache&so on didn't help, not even deleting /data, I really had to delete /system. I'm not sure whether Magisk was the root cause, but running the uninstaller didn't fix the problem.

Is there a instruction how to update without causing damage?

Does anyone else experience constant crashes on this ROM (thor)? I haven't found any mentions in the last few pages. I've had crashes on the 20/09/19 ROM and have the same problem on the latest version.

Cheers
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Nope. Do a fresh install after wiping system partition. GApps, if desired, should go in at the same time. If the problem persists you may have to wipe data too if it contains structures/remnants from a previous ROM.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] nooby_pls:
Thank you. I've done exactly as you described, except for wiping data as well.

I've tried wiping data as well now and have seen two crashes within five minutes from a fresh boot.

I can't pin the crash to a specific thing that is happening. I'll just wait for the tablet to reboot and without even unlocking it after boot it crashes after some time and reboots.

My steps:

Boot into TWRP

Wipe Caches/Data/System in one go

Install ROM and GApps in one go

Boot system

I'd appreciate suggestions for any steps I can take.

Before fully unlocking the bootloader and installing Lineage the device had SafeStrap and a Nexus ROM on it.

Cheers

Edit:

Okay I've narrowed the reason for the crashes down. The device crashes whenever it locks, so either by inactivity or locking the screen.

It hasn't crashed on me during regular use yet.

[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Hum, don't have an immediate explanation. Obviously specific to your device as the noise level would be higher if widespread. It will take some digging on your part to further isolate the issue so [MENTION=5749760]ggow[/MENTION] can determine if a fix is viable. Might also try wiping internal storage; be sure to verify ability to adb push files in TWRP first as you'll need to repopulate ROM/GAaps/etc zips after the wipe. I've had to do this a couple times on HDX devices to recover from unexplained behaviors. That's over 7+ years; not common at all and likely the result of my own handiwork. Good luck.

---------- Post added at 01:24 PM ---------- Previous post was at 01:14 PM ----------

Yep - same behavior on a fresh install. Not sure either as I don't use the Gmail app. Probably have to Google for a solution; doubt account identification "bug" is unique to HDX devices and/or ROMs.

---------- Post added at 01:28 PM ---------- Previous post was at 01:24 PM ----------

Best advise is don't. Slow internal RAM and an anemic GPU make HDX devices ill suited for game play. A low-end burner phone will run circles around this device. It's primary virtue is the panel, not pushing high FPS.

Updating from the first (17th) to the second official nightly (18th) cannot be done with the CM Updater. Error message in the updater: cannot restart in recovery mode. I assume this may have something to do with the Apollo TWPR build I am using (the one from the bootloader unlock thread).

EDIT: ADB sideload does work (but may be less convenient for some users)

EDIT2: No changelogs are currently availabe for Thor/Apollo for CM 14.1 - the CM 13 ones do exist:

https://www.cmxlog.com/14.1/apollo/

https://www.cmxlog.com/14.1/thor/

It is a nice way to see what has been changed. No clue how they are created, I assume based on the build-bot? Or am I using the wrong url?

EDIT3: I tried a few additional custom roms (including the official CM 13) and all of them let me rotate the screen. I assume therefore that this is a CM 14 (or Android 7.x) related issue.

if the device is going to standbye the launcher goes into landscape mode (same as cm13)

sometimes you need to shake your device ->rotation works fine but sometimes it need some seconds to setup

wifi is much more stable than cm13 but not perfekt

going offline after a while in standbye (you have to reconnect)

sometimes you loose the connection for 1 second (only 5ghz) compared with cm13, cm12.1 the cm14.1 wifi works fine

some 3d games are crashing after the device is getting hotter / all of them google play based = same as cm13

i got no error for installing google play games

i used gapps pico from 16.12

camera quality is not so good but works fine here no crashes

maybe we can setup the cm camera snap?

device is much faster and feels more snappy...

i have about 200mb lower ram consume compared with cm13

Bluetooth works with my soundbox other thing aren't tested by me

I'm wondering if re-enabling SELinux has caused sensor / rotation issues on Apollo devices.. I'm not seeing any complaints from Thor users in this area. And a lot of the posts mention it working fine in the initial builds.

Or that if you wipe and start with an SELinux enforcing build its missing some permission to setup 1-2 of the initial files. Where if you wipe and start with the SELinux petmissive build those initial files are setup correctly and then its fine later when SELinux goes to enforcing.

You can change that in the in the "Display" options. Select "Screen rotation" and there enable "Rotate Lockscreen" (English translation may vary).
