question, why wifi does not found 2.4 phone hotspots, different devices?
[Kindle Fire HDX 7" & 8.9" Original Android Develop] bobcat131:
Still Fixing these issures?

This only installs on some, not all Thor/Apollo devices.

I tried it on three Thors and only one succeeded. One Apollo failed.

Any progress?
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Buzzpcsos:
I wonder if the fault lies with twrp. After installing this version on my Thor, I decided to go back onto lineage 14 but no amount of wiping or formatting would clear the storage enough to do a clean install. It always hung on the boot logo despite previously installing from the same source twice before with no issues. I don't try to integrate google or anything else when installing.

The only thing that had changed was that lineage 16 had been installed between times. Surely a twrp wipe and format should remove all of the previous installation.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Try reformatting system partition (advanced wipe action). Also clear/wipe internal storage if you are 100% confident (test it!) ADB file transfer works in TWRP as you'll need to restore ROM zip from a suitable host. Functionality is there since 2.8 but some folks have difficulty getting it working.

Final whacky tip: power down device vs rebooting after wipe actions. Yeah, I know what you're thinking 🙄 yet I have seen that help with HDX flash issues with no logical explanation. Go figure ...
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Buzzpcsos:
Thank you for the fast response, I gave it a try. I formatted every partition and did a restore to defaults too without any luck. I also tried the power down trick after formatting. Left the tablet with animated Lineage boot screen running for about 20 mins before giving up and putting Lineage 16 back in again, when everything went in fast and smooth. So that is what I'm running now.

I did notice that even after formatting the user partition, when I went back in to check it had all cleared down, there was about 23Mb used space being reported. I tried formatting several times even changing from one file system to another but there was still used space being reported afterwards. I have set Data and Cache to F2FS.

I am not too concerned about not being able to go back to L14 Rom as I am sure L16 Rom will continue to improve. I just wondered what had been changed by installing L16.

Finally I would like to take the opportunity to congratulate ggow for his excellent work and continued support for these little wonders, and helping us to recycle old tech back into usefulness.

Thanks. What other 3d games are good?
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
I may need to give 14.1 -> 16.1 -> 14.1 sequence a whirl to better understand where the problem lies. Was preparing to mothball my small HDX fleet but may fire one up a final time to see if I can duplicate your findings.

Edit: On second thought probably not. At this stage it appears 14.1 is the terminal feature complete build for HDX devices. That's not a complaint! 3rd gen HDX tablets had an amazing run thanks to several key contributors on one tireless developer (@ggow) who kept the candle glowing with quality custom ROMs. Time moves on. Those who continue to use/enjoy their HDX should probably stick to Lineage 14.1.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Arthurcheg:
DRM does not work, KinopoiskHD gives an error when trying to play the movie, trailers shows without problems. Doesn't remember screen orientation settings after a reboot. I didn't see ATPX in headphones, only ACC and SBC, the sound lags as on 14.1, it's not possible to listen to something via Bluetooth. We'll have to go back to LineageOS-14.1.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] bobcat131:
I tend to agree. We may have reached the point where further development of HDX custom roms has reached the point of diminishing returns. I thank you and ggow for all your help and contributions.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Buzzpcsos:
That is a fair conclusion. Now moving on from there, are there any HDX owners who have successfully installed L16 and then wiped to revert back to L14 ?

I'm not sure if I am doing something wrong or if there is a special instruction that needs to be run when wiping L16 but after having L16 up and running on my HDX there was no way that I could get 14 to install again.

Do I need to restore to a factory image and then go through the whole process again ? That seems a little extreme. The feeling I get is that some L16 files are being missed by the wiping process preventing me from installing L14 or any earlier ROMs. I have tried installing older Thor ROMs but get a message indicating that I cannot instal an operating system older that what is installed. This was after full system wipe and format of individual partitions .

I would really appreciate information from anyone who would care to share some hints on what I have missed.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] bobcat131:
Here's how I did it. Boot into TWRP via the power and audio+ buttons. Wipe everything and mount system. Finally sideload the L14 rom and pray.

It worked for me. Goodluck!
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Buzzpcsos:
Thank you for the insight to your personal experience. I have now learned how to sideload!

My experiences or returning to L14 were not so productive but I have included the details here for your entertainment. I still think there are some remnants being left after wiping which would explain the error when I tried to load Slim-thor.

Wiped the HDX by using TWRP format data then advanced wipe and formatted everything I could access, finished off with a factory reset. Set all partitions to ext4 in case f2fs was getting in the way.

Sideloaded lineage-14.1-20200705-UNOFFICIAL-thor - left on boot animation for over an hour. Got no further.

Wiped everything as above.

Sideloaded AospExtended-v4.6-thor-20180610-0939-UNOFFICIAL - left on boot animation for half an hour. Got no further.

Wiped everything as above.

Sideloaded cm-14.1-20161225-NIGHTLY-thor - left on boot animation for half an hour. Got no further.

I've returned to v14 some time ago, the unstable wifi made practical use of v16 nearly impossible. I just returned to the last backup, had no problems. I'll test again when new versions arrive, as it generally felt nice to have v16 on the HDX.

On a side note: Since newer Android does not support to turn off wifi on standby any longer, I was using "Wifi Automatic" briefly for that, and kept it on v14 too. Positive side effect: Wifi wakes up without flight mode tricks, just needs to reconnect. And of course nice standby times of 2 weeks and more depending on usage.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] bobcat131:
That's strange. L14 and others wouldn't install, but L16 did install. I would have thought the opposite. Anyone, you got it up and running. Good!

Wuhu. Glad to hear from you. Take your time. Most import you are fine.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] rien-ne-va-plus:
I came to this thread after I had undusted my Fire HDX and realised that Android 4 is unusable for anything other than Amazon. Luckily unlocking the device seems easier these days and after an almost brick I now have Android 9 on the device which works beautifully. Thank you for your work!
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Bwangster12:
Yeah I'm in same boat. Had been using stock FireOS for years until I realized many apps wouldn't run on it anymore. After unlocking and putting AOSPExtended on it, I'm shocked at how useable this is. Looking forward to trying LOS 16 when more stable.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] wllpwr:
For now 14.1 seems to be the sweet spot for me, my Kindle got really toasty with this build and my battery life was bad. I hope this build will see more stability and further improvements in the future :)
[Kindle Fire HDX 7" & 8.9" Original Android Develop] sanjonny:
Just want to say, got new/refurb HDX from woot. Thank god because I broke 2 screens on my old hdxes and so wanted to use it since it still rocks. unlocked it and installed twrp and wiped it completely and installed this rom and it seems to be working great. I use static ip addresses and have not really had any wifi problems so wondering if that might be the issues people are running into. So far I have no complaints with 16.0 and ggow did a great job. I will let anyone know if i run into anything but right now I have a decent fast good sounding tablet again. Wish someone would make high processor tablets again, but nobody seems to want to make a small tablet with good specs. I will say, I wiped it so much that it would not even boot, then installed twrp using flashboot and installed lineage and it works well.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] SheeEttin:
I'm seeing this behavior as well, but I don't see a resolution anywhere in the thread. From TWRP 3.2.3-1, I wiped all partitions, including misc and fota, and installed lineage-16.0-20200924-UNOFFICIAL-apollo.zip. After reboot, it just sits at searching for wifi networks, and in dmesg I see the same firmware crash and "wmi is not ready" messages. I can provide the whole thing or more if it would help.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] i9000usersa:
First of all, thanks to ggow for this amazing rom.

I just installed this on my second apollo I picked up off ebay and everything seems to be working well except one thing: the pin. After I set up a pin, it always says that I am putting in the wrong pin. Strangely enough, it does not require me to put in a pin when unlocking the tablet from sleep, which was initially why I wanted to use a pin. But it requires a pin when I am trying to go into dev settings and it tells me that I am putting in the wrong pin.

I'm sorry if this has been discussed. I quickly skimmed through the thread again but I might have missed it. I saw there was some discussion about lockscreen settings causing reboots but I don't think that's the same thing. (Am I the only one having trouble finding the thread search function in the new XDA app?)

Anyway, thanks in advance for any advice you can give on this pin issue of mine.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] i9000usersa:
Nevermind, it seems it's the same issue. When I rebooted, I ran into the same problem as described with the screen going black and then coming back on repeatedly. I decided to wipe and start over.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] wllpwr:
I had this issue too. I might be wrong, but I'm pretty sure that the way I "fixed" it was by doing a dirty flash from 14.1 instead of doing a clean flash.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] SheeEttin:
No dice. I wiped everything (including fota and misc), flashed lineage-14.1-20200705-UNOFFICIAL-apollo.zip, confirmed I connected to wifi successfully, booted TWRP, flashed lineage-16.0-20200924-UNOFFICIAL-apollo.zip, booted to system (no wipes or any other steps), and got the exact same behavior.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Yep. Answer is lineage-14.1-20200705-UNOFFICIAL. With undocumented Amazon binaries dating back to Android 4 it's amazing Lineage 16 even made a debut on this platform.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] badasschris:
I've just ordered a cheap second hand HDX 7 to use as a digital photo frame and baby monitor (may extend to other uses e.g. alexa, weather display or maybe even use to read books depending how it performs) I'm pretty doubtful I will get a good experience with the stock os so am I correct in thinking I should install lineage 14? Are there any guides on how to do this from scratch for an unmodified device?
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Lineage 14.1 is the goto custom ROM for this platform. You'll need to unlock the bootloader first; not for the faint of heart. See General thread for two options (manual and using 1-click). Good luck with your intended use cases; none are a good fit.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] d07xta:
Hi folks, i own thor and Apollo and have an issue on both with this last build. Both are none LTE btw!

I can flash and Boot the ROM, wifi and BT etc is working but got some drain issue so I investigated bit.

Please find a screenshot and logs, pls don't bully if something wrong since it's my first post! The vendor/bin/netmgrd keeps the CPU busy continuously.

Any ideas? Maybe I did something wrong? In general ty @ggow for making this ROM possible. :)

Thx in advance!
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
You did nothing "wrong"; ROM has not been full optimized for hardware which dates back 7+ years. Stick with Lineage 14.1 for the best overall experience.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] urigg:
Known issue of this rom. You can open a console app, su to root, and do a "stop netmgrd" to work around this. Haven't noticed any disadvantages of this while I was using this rom.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] badasschris:
Thanks will give it a go when it arrives. Why do you say it isn't a good fit? Main thing this has for such a cheap price is a good quality screen so thought it would be ideal if I could get the apps working. If I can't get it working my next thought is to get a Samsung tab s 8.4 but that's nearly 3x the price
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
HDX is custom Amazon HW that does not play nice with external components and some traditional apps. It's primary attributes are panel, form factor and playground for root junkies. Used a HDX 7 as my primary content consumption gizmo for 5+ years; well suited for that role. Anything beyond is an excercise in frustration.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] d07xta:
Ty very much,seems to work. You have made a script or something to do it automatically at start? If yes pls let me know how.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] badasschris:
Received the HDX 7 yesterday and I'm very happy to report that without any tweaks it's perfect for my purpose, the baby monitor app I want to use just works when sideloaded and there is a digital photo slideshow app which works well enough, the only annoyance I have is the charging port makes the cable stick out the front, I did plan to put the tablet in a wooden photo frame to improve the looks but that cable position will make things more difficult.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Happy it worked out! Sloppy reading on my behalf led me to believe you wanted to use on the sending end where it would have performed poorly. As a receiver/monitor the HDX has legs given the bright, high resolution panel and decent audio. As long as the app isn't fussy about the underlying OS you're (obviously) good to go! Nice choice; something to show the little one when he/she is old enought to appreciate your handy work. :)

Happy New Year.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] badasschris:
Thanks! The next step is to disguise it as a picture frame, it's such a nice little device I might use it for reading books/comics as well. I have a tab s7+ but that's definitely too big for books. Happy New Year!
[Kindle Fire HDX 7" & 8.9" Original Android Develop] ggow:
Happy new year everyone!

I have been working on prototyping lineage-17.1. I got it to boot today but it's broken quite severely. Bluetooth is borked completely, USB doesn't work correctly (MTP + ADB). The old and antiquated compat-wireless wifi module will need a lot of work to make it buildable, let alone function on any level.

I'll continue with lineage-16.0 for now and see how much improvement can be made there.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] double-gee:

[Kindle Fire HDX 7" & 8.9" Original Android Develop] Buzzpcsos:
Many thanks, I have been having problems moving back to Ver 14 since 'trying out' Ver 16. The latest TWRP fixed my problems completely. I hope this update also serves to fix the numerous issues that the other HDX users have been having.

One small thing, has support to format partitions F2FS been removed from TWRP or is it just me?

Happy new year to you all.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] ggow:
I'll rebuild TWRP with F2FS support, I created new trees specifically for TWRP and must have forgotten the TARGET_USERIMAGES_USE_F2FS flag.

Glad it fixed the issues you were experiencing. Hopefully do the same for everyone else.

EDIT: Build 3.5.0_9-1 of TWRP is up now.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Buzzpcsos:
Thank you for your fast response. Latest build of TWRP installed and everything working fine. Good luck with Linage 16.0, it looks very promising although the power consumption is a little too heavy at the moment. Looking forward to seeing its progress.

Thank you for the all the roms...

We originally installled twrp-3.1.1-1 along with 14.1-20170531 & open_gapps-arm-7.1-mini-20170603 in 2017, and over time upgraded to the lasted version of 14.1 . Before upgrading to 16 , I upgraded TWRP to 3.5.0_9 then proceeded to follow the directions doing a clean flash.

Everything seemed to work OK , installed a few apps, all went well and seemed great. I placed it on the charger and powered it off overnight, this morning it is stuck in a loop, after boot up, where it says swipe to unlock. I am able to get to fastboot but not TWRP , I can access fastboot options using my Ubuntu-Mate, but can not find a way to boot into recovery.. I tried using fastboot to upgrade TWRP to Build 3.5.0_9-1 of TWRP, but still no good. I am searching for a solution, but can not find it. Can anyone advise how to proceed?

Thanks in advance
[Kindle Fire HDX 7" & 8.9" Original Android Develop] ggow:
If you hold the power button til the tablet turns off. This takes about 10-15 seconds. The try going into twrp holding volume up whilst powering on the tablet.

Also I think if you set any lock pattern that could cause a boot loop at the moment.

When you did a clean install, did you format /data and /system partitions?
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Pajoe:
Thanks for the roms and the personal help

I thought I formated and I also ran the dd commands. I did set a lock pattern which is probably the problem. I left it in the loop pattern because I could not power it off , thinking the battery would go dead and it would power down. After a period of time it went into recovery 3.5.0_9.1

Iit appears I can start over. Do you recommend just going back to the beginning and do the clean flash and if so do I need to run the DD comands etc again? I will not use any lock patterns
[Kindle Fire HDX 7" & 8.9" Original Android Develop] ggow:
I would start clean but don't do the dd commands straight away. I am hoping these sorts of issues should be fixed using the newer version of TWRP.

If you wait a few minutes I am going to post a new build.

A friend just gave me his Fire HDX (thor), and I have unlocked the bootloader and flashed TWRP 3.5.0_9.1 (among others) which seems to work. However, when I install ANY of the LineageOS zip files (so far) in this archive (starting with the 3 most recent), the system fails to boot and instead kicks me back into recovery.

I really don't know what's going on. I've formatted the internal storage, and the installer succeeds, but it absolutely will not start normally.

Happy New Year... Glad to see you! I've a question is it possible to use magisk with this rom or is there any other way to hide root from apps?

PS: If I want to update twrp to latest version I can flash it directly over older version using flashify? (currently using 3.0.0-1 with lineage 14.1)
[Kindle Fire HDX 7" & 8.9" Original Android Develop] ggow:
Magisk should work with this rom. Yes you can flash twrp to the recovery partition. But I would recommend a clean installation if coming from lineage-14.1.
