How about the Fire 10 hd + 11gen?
[Fire HD 8 and HD 10 Original Android Development] Kaijones23:
no
[Fire HD 8 and HD 10 Original Android Development] Dismal.:
For everyone else please don't ask if it will work on your device. It will ONLY work on the Fire HD 8 2018 Karnak. Any older or newer devices will NOT work. And flashing this will not boot on those devices if they have TWRP at all.
[Fire HD 8 and HD 10 Original Android Development] tommy2023:
Hello to everybody,

I've tested Android 11 on this Karnak device and that rom has lot of issues (gapps twrp flash, video driver, magisk, bluetooth ko): according to me is too bugged.

This rom instead is almost perfect, except for the mic issue.

Please can you give us more technical details in order to compile and test a valid microphone driver (kernel/out of kernel side) for this rom (LOS 20.0 Android 13)? i.e. migrating the working driver from Android 11....

By fixing the mic issue this rom would be perfect.

Thanks
[Fire HD 8 and HD 10 Original Android Development] Kaijones23:
This is an build that's been out for testing but I will be working on the issues. It does not need an kernel driver for the microphone to work, it seems that android has changed it's audio configuration and I will look into this issue when I have time.
[Fire HD 8 and HD 10 Original Android Development] Kaijones23:
Do you have logs?
[Fire HD 8 and HD 10 Original Android Development] Kaijones23:
The kernel is been built by the Linaro tool chain.
[Fire HD 8 and HD 10 Original Android Development] traman124:
I’m surprised.. flashed 11 on an HD8 and was able to flash GAPPS, used an OMX patch from the hd10 7th gen to get working OMX, and both Magisk and Bluetooth work fine. Was giving the tablet away but did not want to offload FireOS on anyone.....

Hello bro can you plz tell me how I can also unlock my Amazon Fire HD 8 8th gen. 2018 BOOTLODER with Windows plz reply me bro.
[Fire HD 8 and HD 10 Original Android Development] Kaijones23:
There is no way to do it through windows, you have to do it through bootable ubuntu drive or have an linux install…
[Fire HD 8 and HD 10 Original Android Development] Rahuldas4882:
Thanks bro for replying but unfortunately 😔😢 I don't have installed any linux operating system if you develop it for Windows also then only I will able to use because in the laptop I do it's my big bros and he will not let to install linux so bro if you can or you got any method to unlock BOOTLODER via Windows then definitely update me bro thanku

Guys Gsi roms work on karnak plz reply 🤔
[Fire HD 8 and HD 10 Original Android Development] traman124:
god no. You need to use one of these more specific roms that are built for karnak. Karnak will never have treble support. If you want lineage os read my previous post or see the links @Kaijones23 posted
[Fire HD 8 and HD 10 Original Android Development] Kaijones23:
not going to if you ask like that
[Fire HD 8 and HD 10 Original Android Development] Kaijones23:
i have tried the gsi but it’s only system only arm image it’s buggy but works fine with the gsi from phhusion.
[Fire HD 8 and HD 10 Original Android Development] Kaijones23:
also follow the instructions from the post above please. GSI are unstable and they don’t have vendor specific stuff and i don’t take bug reports from them…., just use the rom that’s in the forums instead for more stability.

I tried to install this ROM but when I finish the installation from TWRp and restart the system, the tablet remains stuck on the screen with the writing Amazon

I tried clearing everything (System, Data, Cache) and reinstalling but that didn't work
[Fire HD 8 and HD 10 Original Android Development] Kaijones23:
did you wait for the device to boot after a minute? it takes some time…
[Fire HD 8 and HD 10 Original Android Development] Giovanni Carraro:
It has been standing on the Amazon writing for about five minutes

In theory, the amazon writing should last very little and go directly to loading Lineage OS

How long should the first boot take?
[Fire HD 8 and HD 10 Original Android Development] traman124:
I actually had this issue, had to use LiteGapps instead of BitGapps (try that).
[Fire HD 8 and HD 10 Original Android Development] drizzt09:
got installed and it boots along with "MindTheGapps-13.0.0-arm-20221227_014216.zip".

I am attempting to sign my daughter in that has google family link parental controls on her account.

It signs her in fine. it requests authorization from me and I approve it. that is all successful.

then it goes to a white screen. updating google apps and immediately fails with "something went wrong" and make me start over with her account again.

Clearly i am on the internet otherwise the 2 accounts would authenticate and I would get the approval request on my phone.

I am guessing the version of gapps installed is missing something for parental controls maybe?

Any thoughts?
[Fire HD 8 and HD 10 Original Android Development] traman124:
Try litegapps
[Fire HD 8 and HD 10 Original Android Development] drizzt09:
Same. :(

Hai guys Can I get the window method to unlock the bootloder of my "Karnak"/Amazon Fire HD 8 (8th gen. 2018).....

I have already tried those modifications on my karnak for to get feature and smooth af but at the end I got about the Linux method to unlock but the fact is that my computer doesn't support the Linux Operation system I tried a lot methods so if any of you guys know the new mwthod of unlocking it's bootloder via window method then make sure to update here first thanks guys and try to find fast 🚴三
[Fire HD 8 and HD 10 Original Android Development] Kaijones23:
sorry there is no method to unlock bootloader through windows. you can try using virtual machine or live usb of ubuntu
[Fire HD 8 and HD 10 Original Android Development] kishi san:
Ok sir no problem but if you can search any new method then tell thanks
[Fire HD 8 and HD 10 Original Android Development] Reynald0:
Hello Sir, at the current time public methods involve you using a Linux Distribution such as Linux Mint to unlock specific hardware revisions that are not hardware patched. That said, that doesn't exclude that a Windows unlocking tutorial exist somewhere and is able to extend the coverage even to patched versions, but it is very unlikely, because the job is done way better using Linux than Windows.
[Fire HD 8 and HD 10 Original Android Development] traman124:
I want to know what computer you have. I'm surprised you have issues with Linux, unless you have something obscure (or a Microsoft surface) you mostly won't have problems.

If you have any questions feel free to dm me
[Fire HD 8 and HD 10 Original Android Development] kishi san:
Yep
[Fire HD 8 and HD 10 Original Android Development] nowell29:
Hi everyone. Thank you Kaijones23 for the rom!

I have had this loaded on my tab for a few months now, but I am noticing that in the last couple of months, the systemui seems to keep crashing. When I open a semi-demanding app, it will fail and force close. If I am really patient, I can sometimes get it to stay open. I have very little actually installed on this thing since I would prefer to run an older chip like this as lean as possible. I installed logcat but I am not seeing anything obvious in the logs. I am not sure what to check or try toubleshooting from here. To temporarily fix, I will boot to TWRP and wipe dalvik cache, but then after a few hours or use it will start failing again.

I generally disable any of the animations in dev options. I use nova7 launcher. Is there a build more recent than Jan 4th 2023?

How can I toubleshoot or help? I don't expect this little thing to be a flagship, but I also haven't seen instability like this since before Android 4.
[Fire HD 8 and HD 10 Original Android Development] traman124:
I kinda saw this as well, some builds of 11 worked better though (for me)

I wish my locked mustang could see such a bright future too one day.
[Fire HD 8 and HD 10 Original Android Development] DerivativeOfLog7:
So I found out more about this issue, and a temporary workaround

If I plug in the headphones and start playing audio, the tablet detects the headphones but outputs the audio to the speakers (using the volume level set for the headphones)

However! If I start playing the audio with the headphones unplugged, even if I set the volume to 0, and then plug them in, the sound starts coming out from the headphones only. If I pause the audio for a few seconds and start playing it again, it breaks and starts outputting to the speakers again; but since it doesn't happen if you pause for just a moment it allows to seek the video just fine without breaking it

So yeah that's a way around it, definitely not ideal but it will work for now for the few times I need to use headphones with this tablet
[Fire HD 8 and HD 10 Original Android Development] DerivativeOfLog7:
By the way, why is everyone using Magisk 25.2? 26.3 seems to work fine on my device
[Fire HD 8 and HD 10 Original Android Development] Reynald0:
26.3 is fine, 26.2 had problems with our device.

Follow the sources if you are curious, the last year taken us 3 days to figure out the bug with TWRP, who knows this year? o_o
[Fire HD 8 and HD 10 Original Android Development] Kaijones23:
The matter at hand is considerably intricate, primarily due to our utilization of Fire OS audio Hardware Abstraction Layers (HALs) as opposed to conventional MediaTek devices. This distinction necessitates a more nuanced and specialized approach to address the issue effectively.
[Fire HD 8 and HD 10 Original Android Development] timpster:
Issues: High (complete) ram use 1.4 of 1.4GB and 85 MB free swap, of a 677MB swap something, guessing it is a file.

It is unusable to the point that I cannot have Fennec with one tab browsing this forum, Pandora radio, and clicking

Find on page

causes pandora to close down.

I was wanting to search the forum for the headphone bug but it was for los 14, not 20.

I assume either nobody posting in this thread has ever tested wired headphones, or, somehow I am the only one with this bug.

When I plug in headphones, volume output is at most, 50% the expected volume, and also plays on the external speakers too.

So it would be nice to see Android components not taking up over 1 GB of memory to leave the ability to run firefox/fennec, firewall program (about 60MB), Pandora (27MB - 35 average)

I switched from pandora to settings, to watxh pandora memory use. Then I switch to fennec again to continue this post. Fennec does the splash screeb again and it looks like it reloaded the page but I have all my text still.

As soon as the page loaded pandora stops playing.

When I switch back to it, the program reloads.
[Fire HD 8 and HD 10 Original Android Development] DerivativeOfLog7:
The issue with the headphone jack is known, see the above posts by the dev talking about it, and also my workaround

For the ram issues, you said in the other thread you didn't wipe /data when flashing this ROM... do it as not wiping /data when changing ROMs is something universally known as a terrible idea and nobody will give you support if you don't do it (or actually, they'll just tell you to wipe /data before doing anything else)
[Fire HD 8 and HD 10 Original Android Development] timpster:
Won't this clear my apps settings etc?
[Fire HD 8 and HD 10 Original Android Development] DerivativeOfLog7:
Yes, but it's an obligatory step when changing ROMs.

If you really want, you can use apps like Neo Backup to backup your applications and later restore them, but have to reconfigure the device

A /data wipe done with TWRP won't delete the internal storage (photos, personal files etc) (

not

format, that will absolutely delete everything)
[Fire HD 8 and HD 10 Original Android Development] timpster:
If I clear /data in twr, will it delete installed programs? This is my first time with a custom system.

I also worry about memory swap. Where is it swapping to?

cat /proc/sys/vm/swappiness = 100/

This is concerning to me because while flash nemory may be just as fast, it does not have thevwrite cycle endurance.

I cleared all amazon folders in the android folder and cleared the caches, both of them.

Memory use after two reboots is leaving 200+ MB free so far, I'll let the system idle for a while and update.

O appreciate the headphone trick, I didn't go through all 15 pages, but did go through all 1,000 posts on the unlock thread.
[Fire HD 8 and HD 10 Original Android Development] DerivativeOfLog7:
Yes, but as I said you can use Neo Backup to backup and then restore your apps if you want to

It's swapping on the flash memory, but you don't have to worry about it. The write cycles are plenty enough even for the swap (this is not a 90's flash memory chip)

And no, flash memory, especially the kinds used in lower end devices like the Fire HD, is definitely not as fast as RAM - swapping is mostly used when RAM is running low, and the OS has to make smart choices about it

And that's exactly why you have to do a wipe when changing rom, it would've taken care of the caches and other things
[Fire HD 8 and HD 10 Original Android Development] timpster:
I will backup some folders and delete the /data soon.

I would like to know how to get root access, so I can shrink the swap and reduce the value. The links for mtk-sudo on the unlock thread no longer work, so does anyone know of another method? Also, would I be able to change the super user passwd?

Regarding memory use:

196MB free on swap of 677, and 279MB free of the 1.4 GB with web browser and firewall. Is this inline with other setups who have cleared data?

3 browser tabs will close pandora, but it is better than it was, I had two tabs open and could switch between programs.
[Fire HD 8 and HD 10 Original Android Development] DerivativeOfLog7:
You can use Magisk for root, but I don't see why you want to mess with the swap size... pretty sure the dev who set it this way knows what they're doing
[Fire HD 8 and HD 10 Original Android Development] timpster:
O.K. I cleared /data and re-installed programs. Memory management still has the same issue:

Fennec with three tabs, (usually reloading one or two tabs if I test tab switching), Pandora stops playing and reloads app if switched to (spotify closes too) and firewall (also rarely, closes once or twice a day) is enough to make apps close.

Is there a way to prevent this as I had 217MB of free memory when opening settings typing mem and checking mem use in developer options result.

This is very similar to Fedora's OOM which will quickly close firefox if it determines that it is using too much memory. I would like programs to continue running with high memory pressure, since there is only 1.4GB and that is not user-changable.
[Fire HD 8 and HD 10 Original Android Development] Kaijones23:
Fennec? did you mean firefox app?
[Fire HD 8 and HD 10 Original Android Development] JimmyK87:

[Fire HD 8 and HD 10 Original Android Development] Alotheone:
Hello everyone. Relatively new to custom rom (so far successfully rom'd Galaxy Tab 2 and Galaxy J7 Nxt), should i go for this one or the more allegedly stable LOS 16? Never got the chance to try LOS above version 15.1, but i partially use my karnak as a daily driver for media. So far i've been reading that LOS 20 works but suffers from a heavy memory usage but i understand that @Kaijones23 would be updating it as well as hinting at a potential Android 14.

2 more things i forgot to ask:

1. Does Android Go Edition play a part in the making of the ROM?

2. Do i ABSOLUTELY NEED Magisk on my karnak? (because the one i flashed is gone and I am only interested in trying different OS, but i read on a thread that Magisk will prevent amazon's stuff from going back on the tablet.)
