Thanks so much to OP for making this. It's great to have up to date android, and I have to say I find the performance of this better than I did on Lineage 18. Thanks.

I'm having a few issues with Chrome, Gmail and Keep. I've tried with both LiteGapps and the ones recommended by OP in post 15.

I add my google account, install my apps. Drive, Docs etc send a notification asking for permission to sync with my account, which is unusual, but it works ok. Gmail and Keep open on the add account screen, and force close immediately. Chrome opens and asks me to add an account, but when I input my details on the add account screen, it says "this account already exists on your device" Which it does. It doesn't let me go any further. Strange behaviour. Anyone else encountered the same? Solutions? TIA

I am trying to figure out how to hide root access.

Even if I get root privileges on magisk and disguise it, I can't hide root access.

I tried a few things, but if I did it poorly, I risked rom not booting.

At least I don't use google pey on this device, but if I could hide it, I would!

Everything is nearly runing now. Thank you for the work. But I have two questions.

1. After boot the the amazon boot logo is in place for round about 60 seconds. And then the lineage animotion starts. Is there any possibility for me to shorten that?

2. When I try to connect to a bluetooth device e.g. a bike computer, for which the vendors software asks for GPS-service, I can not connect to that device, because the fire has no GPS. Can LOS20 fake this?

Hi @Kaijones23, can you please tell me where the variables MTK_PATH_SOURCE and MTK_PATH_CUSTOM are defined?
[Fire HD 8 and HD 10 Original Android Development] @Bill_Dollar:
Thank you for a great ROM @Kaijones23. How can I, as a user, best progress the development of this ROM? Is there a possibility of changing the boot logo or is it impossible due to the boot method? It's it possible to lock the bootloader and still run a custom ROM on this device? Thanks again for the effort on this project. This makes for a great tablet once the Amazon junk is removed.
[Fire HD 8 and HD 10 Original Android Development] jumstec:
I've seen this question once in a Lineage 16-18 thread, why is there no 64-bit support?

I also saw a comment that the kernel itself supports 64bit.

Sorry to ask a question that may have been answered many times, but please tell me.

Thank you.

Hey; I adore your rom! The latest version works amazing for me!

Youtube works

Reddit videos work.

bluetooth works well

I'm noticing the tablet itself is quiet as anything. I thought it was louder when I first got it, but I'm probably just making things up.

would a guide like this:

https://xdaforums.com/t/increase-speaker-headphones-volume-stable.4070111/

likely be my only method of increasing the max volume?

Is this advised?

think this might have been an issue with using a generic file/profile instead of something "tuned" to the HD 8.

Thanks a lot regardless!

EDIT:

I just noticed this:

"Well, for it to be 64 bit we would need 64 bit vendor blobs, no Amazon device has 64 bit support so I don't think this one is possible

Although the chipset itself supports 64 bit mode, it's just 32 bit OS"

https://xdaforums.com/t/rom-unlocked-karnak-lineage-16-0-04-june-2020.3981685/post-82661031

"so its impossible to get 64bit os running on fire tablets despite it having armv8 soc and kernel?"

"i could be wrong, but it is possible, but someone would have to make the rom from scratch. 32bit works just fine in my opinion... And this is the best rom i have tried on the 8hd"

Thats probably most of the answer you're looking for!

I remember when I tried building 18.1 that by mistake I builded the 64 bit version, but it couldn't boot, thank you for explaining about the vendor blobs.

The final problem you will face is the physical drain of the battery.

For this, you must either (1) replace the battery, (2) purchase a new battery, or (3) abandon this device.

(1) Replace the battery. Replace it yourself.

One way is to purchase from newpowor99.

However, I am not sure if you need to pay $40.

Also, in some cases, non-genuine batteries can go bad quickly.

One way is to purchase another one and transfer the battery.

(2) If you buy a new one, do not assume that you will get exactly the same one as your current device.

The defects will probably have been corrected.

As for (3), it is no longer a solution.

It means giving up.

But even if you replace the battery, this tablet itself will soon reach the end of its life.

Something I've been trying to say for a while now, but forgot, thanks for the great Christmas present!!!

I'm very worried.

There is nothing I can do right now but I hope you find a good job.

Good luck! Let me know if there is anything I can do to help you Kaijones23

We have two, not new but properly functioning 2018 models that we can donate.

However, it would be difficult to send them to Las Vegas.

Also, as mentioned upthread, it would be difficult to get a new device that can unlock the bootloader.

I still think that we are reaching our limits in terms of physical aspects. If one day it stops booting, it is a chip failure.
[Fire HD 8 and HD 10 Original Android Development] Reynald0:
Won't be a bad idea to setup something like this for Kindle Devices Research:

https://ko-fi.com/

Without donating new devices to the devs, I think will be hard to find new exploits, but that is just my opinion.
[Fire HD 8 and HD 10 Original Android Development] musicmanjp6:
This new ROM motivated me to break out my old HD8 again and get it setup for my daughter to use instead of my iPad Pro.

Great work as always, Kai!
[Fire HD 8 and HD 10 Original Android Development] tsukeyomi:

Just wanted to ask @Kaijones23 , will there be more updates to this ROM or are you basically done for now? Thanks.

Like someone else pointed out, the tablet is definitely quieter with this ROM. Not horribly, though.

While video streaming does work, after about 20-25 minutes of it, it stops for some reason. I thought someone else had reported the same problem, but I've been going through a lot of threads recently and it may have been a different one.

At first I tried playing an hour-long video with NewPipe, but was watching it with the audio turned all the way down. The image froze maybe ~24 minutes into the video.

I tried again with NewPipe and a different 1hr+ vid, this time with the audio up, and the image froze again around the 24 minute mark, but the audio kept going. I tried to move back or forward to see if it would fix it, but then it would no longer load at all.

Then I tried playing the same video in a browser (Privacy Browser, as earlier suggested). I was able to skip ahead to where it had left off in NewPipe, but then another 25 or so minutes later the video stopped and there was a circle spinning infinitely.

Saving the videos locally with NewPipe and then playing then with VLC worked fine.

These issues definitely won't make me give up on this ROM or anything, but I thought I'd report my experience thus far. I'll keep trying things.

Thanks for the love on the Karnak.
[Fire HD 8 and HD 10 Original Android Development] CCarson:
Wow, what a great ROM! Thanks for your hard work. This tablet is running far faster than the lineage 16 I was using before, and the creeping wifi disconnect problem is resolved. Thank you again and know that your efforts have kept another aging-yet-viable device out of the landfill, along with all its toxic materials.
[Fire HD 8 and HD 10 Original Android Development] Kovaelin:
Compared to 18.1, this version seems more stable. It doesn't have the odd charging/lockout issues.

Regarding to some of the earlier reports of not being able to boot to TWRP, I did encounter the same issue, but after booting over three times (while continuously holding volume down), it did eventually start up.

Great work! Thank you very much for staying dedicated to this particular version of the HD8 this long.

Is there any solution for "failed critical init step 4" error when rooting with mtk-su?

or a way to downgrade maybe?

I am trying to root fire HD8 2018 FireOS 6.3.1.4 in order to install LineageOS 20
[Fire HD 8 and HD 10 Original Android Development] musicmanjp6:
You are going to need to follow this guide (which includes downgrading to 6.3.0.0) to prep for installing a ROM:

Fire HD 8 (2018 ONLY) unbrick, downgrade, unlock & root

Changelog: v2 - Fixed the issue with the screen Make sure to read this guide completely before starting. It requires you to open the tablet, however you don't need to solder or use any advanced tools. This is only for Fire HD 8, 8th generation...

[Fire HD 8 and HD 10 Original Android Development] masterpost2004:
Thanks for your reply. I already tried it but I was unable to get into the recovery after running "./fastboot-step.sh

Anything else I can do?
[Fire HD 8 and HD 10 Original Android Development] jumstec:
You may have already done this, but did you turn the screen off and on once?

Have you tried amonet-3?

[UNLOCK][ROOT][TWRP][UNBRICK] Fire HD 8 2018 (karnak) amonet-3

Read this whole guide before starting. This is for the 8th gen Fire HD8 (karnak). Current version: amonet-karnak-v3.0.1.zip This is based on xyz`s original work, but adds some features such as reboot to hacked BL. It also intends to simplify...

xdaforums.com

Also, did you send the data correctly?

It should not fail 99% of the time, but I'm not surprised that it still may not start!

Finally, the text on amonet-3 says

I know this is old,

I wish you well.

Compared to lineage 16 (when rm was first started) there is an increase of about 100 MB.

When launching an app that uses a lot of memory, try going to developer mode -> running services and stop the app.

If we added a high speed SD card and a kernel with Swap, we could increase the RAM tremendously. Im working on it...but am new to full builds
[Fire HD 8 and HD 10 Original Android Development] jumstec:
1.fire tablet storage is slow emmc. It is not recommended to create them on internal storage.

2.sd card reader is also not flattering fast.

3. I don't have detailed knowledge about this, but when you type the command "cat /proc/cpuuinfo" in termux, there should be an entry called "features".

If either swp or swap is listed here, swap can be used, but this terminal does not have swap.

Edit: works awesome. Simple update from 18.1, but very nice upgrade. Great work @Kaijones23. Sorry for your job loss and hope you find something soon.
[Fire HD 8 and HD 10 Original Android Development] Kaijones23:
Why are you trying to build the microg version of the rom. There is a guide to install it without doing the need of building it because it takes a lot of time. https://github.com/nift4/microg_installer_revived. If you want to contribute then you can create a fork and then create a pull request to the repository and then i can test the changes of the build before releasing.

Hi! Recent graduate here, a great tip I've learned is to find connections (especially on LinkedIn) that are able to refer you for a position. Cold emails, messaging recruiters, and knowing someone will give you a greater chance of landing an interview rather than mass applying.

Hi. I would love help to solve what I believe is a bootloop after I flash Lineage OS 20. I'm a newbie to android stuff, so probably some simple mistake. I've tried to follow this guide exactly, but all I get on reboot is the Amazon boot logo.

1. I successfully followed xyz`'s guide to brick, unlock, and root the device. https://xdaforums.com/t/fire-hd-8-2018-only-unbrick-downgrade-unlock-root.3894256/

2. Boot to TWRP no problem

3. I wiped System, Data and Cache, but not Dalvik, Internal Storage or Storage

4. Pushed the Rom with ADB and installed it from TWRP. That finishes without errors

5. I did not flash Gapps

6. Reboot, but only get Amazon boot logo. Nothing happens even after 20 minutes.

7. I've tried reflashing and reinstalling the rom.

8. I re-downloaded rom and checked with sha256sum to make sure I didn't get a corrupted download. Still the same. I can revert back to FireOS 6300 with no problem, so I don't think it's a hardware failure.

I don't know how to troubleshoot on android, but am comfortable with cli in linux so should be able to follow directions. I'd appreciate any help you can offer.
[Fire HD 8 and HD 10 Original Android Development] lilgman:
TWRP is 3.2.3-0. Not the newest version. Is this a problem?
[Fire HD 8 and HD 10 Original Android Development] lilgman:
Lineage18 seems to work fine, following the same procedures, so I think the problem must be deeper than a simple mistake.
[Fire HD 8 and HD 10 Original Android Development] Kaijones23:
TWRP does not need to be updated, if it works , it just works. I tried the recent version and built it and it came out broken by not patching the boot image.
[Fire HD 8 and HD 10 Original Android Development] jumstec:
I've had a few times when the roms didn't boot up, but in this case, rebooting the system started up fine.
[Fire HD 8 and HD 10 Original Android Development] lilgman:
@jumstec Thanks for the suggestion. I saw that reboothing solved the problem for someone on this forum (maybe you), so I did try quite a few times. I'm sure more than 10x plus reflashing. I'm using LineageOS 18 at the moment which works great except for the browser constantly crashing. I don't understand completely, but @Kaijones23 seems to be aware that there is a problem. I'll keep an eye on this thread in hopes someone else smarter than me can fix it! It seems like version 20 is the best since 14.

Installing ARM Gapps from first post is unsecessfull. This ROM needs ARM64 Gapps. Do You think, the x64 system is good idea for 1.5 Gb RAM ?

After first boot I not have option to enter to my Google Account. I entered in acoount later. But Gapps not have PlayMarket, and after manualy installed Chrome - its not see Google Play Services.

Maybe Gapps from first post not compatible with this ROM ?
[Fire HD 8 and HD 10 Original Android Development] jumstec:
This terminal is not compatible with 64-bit.

To be exact, there is a 64-bit kernel, but it is in 32-bit mode due to vendor blobs.

Therefore, if you want to use 64bit, you need to rebuild the OS (i.e. 64bit vendor blobs) from scratch.
