Okay, so I've been reading for a couple days now, and I know the exact process that I want to take to Permaroot my MT4G and get S=Off, and I understand very clearly what those terms mean and why I want them.
Once I started looking into what to do beyond that, I got really, really confused.
If someone could refer me to somewhere so I can read more, I would really appreciate it.
For starters, I don't understand what flashing is. I also don't know what pushing files via the adb is. I don't know what the difference between a ROM and a kernel is.
^^^^All of those would be helpful
I guess I'm just confused about what to do now. Should I now set up the SDK on my PC and configure the ADB? Or should I flash Clockworkmod and do a nandroid backup? Neither?
Once I've done that, should I find a kernel, a ROM, or both? I know I want Gingerbread, I want OC capability, and I it stripped down (missing bloat), but I also want stability and for things like WiFi to work. On top of all of those questions I posted above, does anyone have any recommendation for a ROM/kernel like that?
Sorry about all the questions, and thanks.

Edited: added Later
ADB is a commander center/protocol (if you will) that allows you to control your phone via a PC/Mac/Linux. You can push files which would be taking the file and "pushing" to the phone. Or "pulling" files from the phone and putting them on the computer. It's simply as it states, pushing and pulling the files.
To see what a Kernel is read This.
A ROM is the phones physical Operating system. Similar to what Window, Mac or Linux world be.

Before you can flash Clockwork Mod you need to root your phone and turn s=off. For one of the methods, - before you can start you need to set up the ADB (Android Debug Bridge). See my signature for the quickest and most painless way to get that set up. You will also need VISIONary.apk. A quick Google Search will find it for you. Link

If you want a 2.3 based ROM you will need to flash Recovery image 3.0.0.6, link can be found in my signature, and hit up the development section to read reviews on different ROMs. I personally like the plain AOSP look so that leave Cyanogen(mod). But i know TeamRoyal has put together some newer ROMs that i haven't tampered with yet.
I do everything on my phone through CWM (clockworkmod) or terminal emulator, so there's no need for a PC, unless to download the files and transfer them to my SDcard, as I don't understand adb. Anyways, I'm gonna explain this very short and sweet cuz I was once in your shoes, and remember how much I had to read to understand something That could've been explained so simply.
Think of it this way. You're building the software version of a car. Now, if the whole car is the ROM, then the engine is what would be the kernel. And flashing would then be another word for installing , Now, a toyota with a ferrari engine, would be a custom ROM. While a toyota with a ferrari engine and BMW insignias all over it would then be a custom themed ROM.
**Remember, you can never install a car on something, but you can always install something in a car**
Ex. You can never flash a ROM on a kernel, but you can always flash a kernel on a ROM.
Anyways, first off, you will need CWM recovery to flash. Get it from the market. In the app itself, flash (this is the "flash" in the app) recovery 3.0.0.6. This will flash (this flash is not in the app) anything; any ROM, any kernel, etc. as long as its a FLASHABLE ZIP.
To boot into the recovery (the place you do flashing), hold both volume down and power buttons down as you either turn on or restart your phone. The screen you see is the bootloader. Choose recovery using the volume buttons, and use the power button to select it.
Going to flash a new ROM? Do a factory reset (in recovery), wipe cache (in recovery), and wipe delvik cache (this is in advance in recovery). Then install zip. Its pretty straight forward from there.
Going to flash an updated ROM, skip factory reset (as this deletes all data on your phone) and do the rest.
After you've flashed the ROM, you can now flash the kernel.
Note that, kernels are ROM specific. Read what kinds of ROM's the kernel is for before you flash it.
There, easy as pie, yeah? Hope that helped.
I recommend cyanogenmod 7 (Gingerbread based ROM) with faux's kernel (Gingerbread based kernel)

Neidlinger's got your back.
1. Glad you're reading before doing. What a welcome change of pace!
2. Flashing is the process of installing new software. We "flash" it to the phone's memory.
3. ADB is using a computer to control the phone via command-prompt from DOS. Push is a command which sends a file from your computer to your phone. Do a search, there are lots of good guides on ADB. TrueBlueDrew made one just recently that I highly recommend.
Here's Drew's thread. Don't forget to hit his thanks button! - http://forum.xda-developers.com/showthread.php?t=928370
4. Start with Clockwork Recovery and a nandroid backup. That's good practice. CWR2 is compatible with Froyo (2.2) ROMs. CWR3 is compatible with Gingerbread (2.3) ROMs. CWR 3.0.0.6 is compatible with BOTH. Very convenient.
5. I say start with CM7. It's extremely stable, even though it's still in development. A ROM is a complete OS replacement for the phone. ROMs contain kernels, which control the most basic hardware, such as processor. If you flash a custom kernel on your stock ROM, you can overclock it more. You can also flash custom kernels on top of custom ROMs for different battery life, clock speed, etc.
To be honest I don't even bother with custom kernels since this phone is so damn fast out of the box I really don't see the point.
QUICK TIPS FOR CM7 - On your first boot, let it sit for 5-10 mins before setting up. There are background processes running and interrupting can harm stability. BEFORE you sign into google for the first time, after it's finished sitting, reboot. This will clear out any wifi glitches and give you smooth sailing.
Have fun!
BTW, I think most ROM's have a kernel already built in. People install custom kernels because they can have fixes for bugs, help with battery life, overclocked frequencies, no lags, etc. Otherwise, you can just flash the ROM, and if you're satisfied with the kernel its running on, then obviously you'll have no need to flash a custom kernel.

This is pretty much spot on. The developers have included kernels that they feel make the OS preform at it's peak. and most of them will allow for overclocking. However on some of them you may need to use a program called "setCPU" to adjust the frequencies. Cyanogen(mod) will have this built into the ROM natively. However most of the veterans will not promote running your phone in an over clocked status 100% of the time. most of us leave the phone at 1Ghz or slower. There are physical reasons, ie the constant expansion and contract of the chip isn't good for the mother board.
If i were you i'd stick with the Stock Kernel and leave it running as it. That way the developer can adjust their ROM, if you use an 3rd party kernel they aren't familiar with the coding so it's not going to act correct.
I'm not putting down what the kernel coders do, they do an awesome job. but for a n3wb i'd leave well enough alone.
Alright i have been keeping an eye out on a few things and came across BootManager which is a newer app that allows you to easily flash between several roms! Which of course is awesome if you want to try new ones out without reflashing as often. Unfortunately im am not quite as wise in the Android scene yet as i like, new to it with my Acer Iconia as i am, BUT i have been corresponding with the developers for BootManager and they have given me a link so we can submit the Acer Iconia to be added to the devices that can use Bootmanager!
I just don't know how to give them the variables they need!
Could someone that does know how to get the variables needed, (through adb shell or whatever) kindly submit it to them? Here is the link they gave me for submitting new devices, if you do do this, please post it here, so they don't get a bunch of repeat submissions on it, also, so i can keep an eye on the app and get it when they update it accordingly! Thanks very much!
Edit: I can't post links yet, cause i have not posted often enough. Please send me a message and i can give you the link that way! Or just close the space below and use it.
init2winitapps. com/submit_device.html
I'll do it in the morning.
Make damn sure they know they have to run "itsmagic" before/after ANY flash operation (I can never remember which, that's CWM's job!)
I did it too and i sent also a mail to the developers about itsmagic script!
good luck
If you read the information about this program.how it works and the phones that it supports will tell you it will most likely work on our device.THEY SAY WORKS ON PHONES ONLY.and only those WITHOUT LOCKED OR SECURE BOOTLOADERS
But you never know. They might put the efforts to write a new bootloader for this device.the program works by moving the bootloader.well no fifteenth then any other boot manager.
if im wrong and they make it works. I would buy it first.
Goddess erica.
This was posted a while ago and it doesn't appear that the a500 has been added to the supported device list. Has anyone been successful in getting this to work? I want to try it but I'm not sure what issues I might run into if it doesn't work. I need to make sure a Nandroid restore can fix whatever issues might be caused before to try it.
IF i remember right it says on there site this can ONLY WORK WITH UNLOCKED and not encrypted BOOT LOADER DEVICES. I TO Talked to the dev way way long ago..as for this to work they change the boot target in the boot loader to look at there software . then it will boot from there..
kinda like grub to a normal pc.. with the bios being the primary boot . If this makes any sense..
so i think it cant happen.. in the linux thread in our dev area .. someone in the first few pages it talkes about this very app and the flashing the bootloader out.. Dont think they ever figurerd a way around the security..
sorry simple answer is ABSOLUTELY NO WILL NOT WORK
THANKS ACER
I'm confused. My a500 doesn't have a locked boot loader. Thats the reason I got it. I have Thor's recovery loaded on it and I have been able to flash Roms without issue. To boot into recovery I just hold down the volume button and boot the device. I can load custom kernels or pretty much anything else I want. Am I misunderstanding what an unlocked bootloader is?
I had a Razr previously which had a locked bootloader and the only way to flash was to use a bootstrap because it had a locked bootloader. I had loads of problems with it which is why I swapped it out for the Galaxy Nexus when it came out. Both my a500 and Gnex are flashing like champs.
Where there later version of the a500 that had a locked boot loader? I don't think mine does.

Not locked, but encrypted, we use a magic script called itsmagic to bypass the encryption.

Ah. I always wondered what itsmagic did. I get it now. Damn. Is there currently any tablets out there that do not have encrypted or locked boot loaders?
Not any good ones.. welcome to the new communist Tech generation...
they want our devices to be disposable.
Just wondering if anyone has looked into this, and what it could possibly mean for our device if we could be merged. Apparently there's no need for special kernel modules, bootloader edits, or KEXEC, and I think it would be pretty cool to be able to use multi ROM to boot back and forth between stock and AOSP.

This article was the first I'd heard of it. But it does seem like it might be something easy to implement. It's basically multi ROM, but without all the requirements.
Looks interesting.
is it possible to dualboot into that one OS called sailfish or something? even ubuntu mobile?

This is to make the phone able to boot two different working roms. Say, you will be able to boot stock or RR without changing roms in TWRP. It won't boot roms that haven't been ported to our phone...
This is very, very interesting. I love the thought of just using LineageOS or RR for everyday things and then just switching to stock when I want to use media and enjoy the fantastic sound.
I'm not a developer, but I'd like to help/contribute in any way possible if someone's working on bringing unofficial support to the Axon 7.

Very true. However, it makes ROMs easier to port and for more people to test, as then people can try them out without wiping their phone each time they want to try.
I was able to port and build right up until the last step where you generate lk.img and fastboot it to the phone. I'm running Linux inside a virtual machine and it doesn't seem to want to communicate, though adb does work.
I might try on the weekend to boot linux off a hard drive and see if it will work..
In the mean time, if someone else wants to try to build, it's really simple just follow these two guides:
https://github.com/efidroid/projectmanagement/wiki/[EFIDroid]-Getting-Started
https://github.com/efidroid/projectmanagement/wiki/[EFIDroid]-Porting-a-new-device
I tried again, but when I fastboot the generated lk.img to the phone, it just turns off instead of loading the splash screen.
I used the TWRP recovery .img for the create_device step. Maybe that's unacceptable, though it built the lk.img without error.
Anyone else trying this?

Did you try this fix for arm64 devices?
https://github.com/efidroid/projectmanagement/issues/89
Seems you need to dump aboot to check what's the correct address for LK to boot.
Edit: also did you try using freeza Beastmode boot.img? Probably that's better
Thanks for the reply.
I dumped aboot and replaced the address but sadly it just makes the phone reboot, I used the beastmode boot.img at the same time.
I'm a bit in over my head at this point hah, but someone in that thread had the same results..

I'll try the suggestion of using lk_origdtb.img. I'll have to ask about his instructions to rebuild lk.img, I'm not sure how to repack it.
This might get me close http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images
But this is lower level than I'm used to, I'm not sure which file(s) constitutes the ramdisk.

you can contact @npjohnson or @m1cha with your compiled LK or boot maybe they can help
as they have fix Nexus 6P LK with no uefi boot
Read First: This method is relatively drastic, and will hurt device performance some. You should only use this as a last resort, if the more basic methods of fixing a soft brick didn't work (e.g, factory reset, flash stock firmware, etc.)
*Update 7/30: On my 6P, I found that the original kernel with this mod was using pretty much 1.5 cores, instead of all 4. People with the 5X were also reporting this, so I modified the images to utilize all 4 cores better. It helps performance a lot (able to beat stock 6P in some Antutu marks now, and play intensive games), try it out if you haven't yet!
*Petition:
I made a petition for Google to officially release and sign modified boot.imgs, so that people with locked bootloaders can fix their devices too. Check it out here. (I apologize for dumbing it down so much, I wanted to make sure everyone could understand it)
*Changelog:
8/26 - EX kernel for Android O uploaded.
8/22 - Android O working, boot.img and source uploaded.
8/08, 2nd Change - Added boot.img for 48C firmware (August security patch).
8/08 - Updated EX kernel to version 4.1.2. This updated zip adds the CPU utilization patch to the init.elemntalx.rc, instead of removing the old init.angler.rc and copying the new init over. That should mean more compatibility with Roms/kernels that modify the init.angler.rc. I also modified the camera-daemon to use cpus 0-3 instead of 0-2, so hopefully this should make the a camera bit faster too.
8/07 - Added boot.img for 1 core, just to see if it would work for devices that didn't work with the 4 core image.
7/30, 2nd Change - Added universal EX zip, this zip should modify your kernel to use only 4 cores, and it should modify it to utilize all 4 cores. You can flash this over most ROMs and it should work. Also added a donation url, and this changelog.
7/30 - Updated this fix to greatly improve performance. Before this fix, the device was only using 1 core for foreground tasks, now it will use all 4 cores. Also revamped OP, and added Marshmallow images.
7/23- Created this fix, stock boot.img, twrp, and EX kernel added.
*What this fix does, and how to apply it:
The problem:
The problem with most of the devices in a BLOD, is that a hardware failure related to the BIG cluster has occurred. This fix remedies the problem by disabling the BIG cores. Unfortunately, this does mean that you will take a performance hit. However, I am continually working on ways to improve the device's performance.
The update: If anyone remembers device performance with the first fix, it was hurt a lot, however, after finding out that the device was only using 1 core for all foreground tasks, I modified the ramdisk to utilize all 4 cores more effectively, and it helps a lot.
Requirements: For this fix to work, you need:
A brain
A computer
A bootlooping 5X with an unlocked bootloader/OEM unlocking enabled
The modified files of your choice.
Fastboot on your computer (preferably installed system wide). If you do not know what this is, or do not have it, look at this post. Answer yes to all of the prompts to install it.
How to apply the fix:
Boot your phone into bootloader (hold power and volume down).
Connect your phone to the computer.
Go to the folder where you have the modified files, then hold shift and right click in a blank space, click on "open command prompt here" in the menu that pops up.
In the command prompt: type "fastboot flash boot [name of the file here]" and then press enter. If you're flashing TWRP, replace boot with recovery. (Linux users, make sure you're running as root)
Edit: with the new universal EX zip, you don't have to flash the modified boot.img now, you can just flash TWRP, and then flash the EX zip, and everything should work.
Boot up your phone, and hopefully it should work!
*If your phone is bootloader locked/OEM locked:
You can try to get your phone to boot long enough to enable OEM unlocking. Some users have reported success by freezing their phone for a bit, then booting it. Others have let their battery drain all the way, and then tried to boot their phone, but the most successful method seems to be heating up your phone (a lot).
If you do attempt any of these methods, make sure you have time and patience, as it will take a long time.
To enable OEM unlocking and unlock bootloader:
Go to settings.
Go to developer options, if you do not see that, go to "about phone", scroll to build number, and then tap it 7 times. You should now see developer options in settings.
Once you're in developer options, click on "OEM unlocking" and accept the prompt.
Now reboot your phone to bootloader, connect your phone to the computer, and type "fastboot flashing unlock" Your bootloader should now be unlocked.
*Downloads:
Boot.img from Android O DP6: Download | Mirror. This Image is the from the first official release of Android O, and is modified to use 4 cores. As a bonus, it also disables forced encryption. Thank you to @xls654 for figuring out how to get Android O to work.
Boot.img from stock 48C, 7.1.2 firmware (August security patch): Download | Mirror. This Image is modified to use only 4 cores, and is modified to utilize the 4 cores more effectively. I have had multiple people on the 6p say that first boot takes a while after flashing this, so just wait about 20 minutes before you declare something is wrong with it.
Boot.img from stock 47Z, 7.1.2 firmware: Download | Mirror. This Image is modified to use only 4 cores, and is modified to utilize the 4 cores more effectively. I have had multiple people on the 6p say that first boot takes a while after flashing this, so just wait about 20 minutes before you declare something is wrong with it.
TWRP version 3.1.1: Download | Mirror. This TWRP image is modified to use only 4 cores.
EX kernel version 5.03, for Android O: Download | Mirror. EX kernel for Android Oreo, modified to use 4 cores. You must flash it over the 4 core boot.img for it to work.
EX kernel version 4.12, universal zip: Download | Mirror. This zip is modified to use only 4 cores, and it will also apply the speed fix. Flash this in TWRP. I highly recommend you flash this, as it improves device performance notably, and disables forced encryption. This kernel should work with almost any other ROM, and it applies the core utilization mod from the first image, thanks to AnyKernel.
Boot.img modified to use only 1 Core. Some people were reporting that the 4 core images weren't working for them, someone suggested that I make a 1 core version to see if that helps at all. Here it is: Download | Mirror
For Marshmallow:
Boot.img from the latest 6.0.1 20K firmware: Download | Mirror. This boot.img is modified to use only 4 cores, and is modified to utilize those 4 cores more effectively. Untested as of now.
Ex kernel version 1.2.0 for Marshmallow: Download | Mirror. This is the latest EX kernel for marshmallow, it will keep the core utilization mod from the above image, and should work on almost any other ROM, thanks to any kernel. Untested as of now.
*Source Code:
Source for 4 core Android O DP6: Source.
*Tested custom ROMS/kernels
you should be able to use almost any ROM with a stock based kernel, just flash the EX zip over it.
If you have a custom ROM/kernel that worked for you, let me know and I'll put it up here.
*To improve performance slightly:
Flash a custom kernel. I will upload more kernels as people request more, so stay tuned.
Flash a custom ROM. Once again, I will upload more as people request more, so stay tuned.
Overclock the little cores. It can slightly help offset the lost performance, on my 6P, I have mine overclocked to 1632MHz, and it works perfectly for me. Edit: I actually recommend not overclocking. Many people have reported their Little cores failing, so I would go for longevity on this device, and keep it at stock clocks, or even underclock it. The speed difference you get from overclocking is negligible anyways.
Disable animations in developer options. Seriously, as soon as I found out about this tweak, I've used it on ever single device I've owned, it helps a ton.
*Credits:
@rchtk, His post here gave me the idea for how to modify the images.
@flar2, He built the Elemental X kernel for this device, I merely made a small modification to his kernel to use 4 cores. In no way am I trying to steal and/or discredit his work.
The TWRP development team, they built the TWRP recovery for this device, I merely made a small modification to their recovery to use 4 cores. In no way am I trying to steal and/or discredit their work.
@xls654, He found out how to get Android O working with 4 cores.
*FAQs:
What's the password for TWRP/Why is TWRP asking for a password? - In android 7.0, Google added forced encryption to the data partition. To get around this, click cancel when TWRP asks you for a password, and then factory reset the device. Then you can flash EX kernel/Magisk to disable forced encryption.
Why am I getting an error when I try to flash the images? - Your bootloader is probably not unlocked, try running the command "fastboot flashing unlock", If you get an error there too, then you will have to enable OEM unlocking before you can continue.
It's not working for me, how do I fix it? - My only advice for that is: "Flash the stock firmware for whatever version image you're trying to flash, then reflash the images again" If you're stuck on the boot animation, wait at least 20 minutes before you declare it's not working. If none of that works, chances are you have a different problem.
Does EX kernel have the new speed fix? - Yep, the EX kernel zip should apply the 4 core fix, and the speed fix. It should also work with almost any ROM, including stock.
I would like to help as many people as I can, however, I am much more likely to be able to easily help you/reply to your post if you clearly state your problem and the steps you attempted to fix it. I will be much less likely to reply to posts such as "omggg i flashed the image and my phone won't boot helppp" Please read through post first, I did not spend time typing up this OP for no one to read it. If I can see that you read through the OP and have attempted all the steps, then I will be much more willing to help you.
I set up donations on my profile, for those of you who want to donate. I have spent countless hours modifying, flashing, testing, and helping, don't get me wrong, I love doing this and helping y'all out, but donations really keep me motivated to keep going, and donations also will help me fund new equipment and devices that will help further my android development.

Didn't work
I flashed the image and the bootloop is still there, thanks for the effort though. Anything else you'll need for the 5X to continue your research ?

dang :/ If you can get into twrp, pulling the "console-ramoops" would be helpful, but I don't think you can boot to twrp.
this actually fixes my phone, i do the same with elementalx kernel i disable the big cores as soon as my phone boots up so this img is really handy

Yeah Twrp is not working.
So I just flashed this over the May 2017 build and my phone boots and is working just fine, albeit a bit slowly.
I'll update to the latest build and reflash but for now you can say it works as intended. Thanks for the effort
Gonna try this

It's worked for me. Phone is slower, and taking picture with hdr+ is okey but processing is very slow. I turned off animation, is there anything else I can change so phone can perform faster ?
Any idea how long this should take? I managed to get into my 5x and enable debug mode / OEM unlocking
I ran the fastboot flash boot N2G47Z_4Cores.img command and its been stuck for about 5 minutes
This works, thanks. First time I've been able to boot my 5X in months.

I uploaded a custom TWRP image and EX kernel zip. Try flashing the modified TWRP, and then flashing the modified EX kernel, and see if that works.
after trying again I was able to get it to write successfully however the nexus 5x is still bootlooping, this is an original hardware revision nexus 5x if that helps

I updated the OP with a modified EX kernel, and some tweaks to make your device faster, check it out to see if it helps your device.

My first time took around 10 minutes to boot I think, if it takes over 20 minutes, reboot your device and reflash, and if that fails, update your firmware to the latest version.

Are you upgrading from stock firmware or a custom rom? This boot.img is for the latest 7.1.2 build. Unless you have files that you can't afford to delete, I would recommend reflashing your stock firmware with the latest version.

Awesome! I just want to say how much I love your kernel, it makes this fix much more viable.
update: I was able to install twrp and boot into that, but its asking for a password.... @XCnathan32 is there a specific password you set or should "default_password" work?

default_password didn't work for me, I just clicked cancel when it asked for the encryption, and then I factory reset the device through TWRP. If you have important files you can't delete, you can try just flashing EX Kernel, as I don't think EX needs to access the /data partition.
Update 2 : Seems I was able to just cancel out of the password prompt. Flashed Elemental X and it looks like its booting!
Awesome job my friend, you fixed the (temporarily) unfixable. I'll play around with this for a few days and report back.
Thanks!

So I found a bootloop fix for the Nexus 6p here, and some users reported having the same problem with their Nexus 5X.
I do not own a Nexus 5X, but I made a modified boot.img the same way I made the modified 6P image. It simply disables the big cores, as that's what was preventing the 6P from booting.
Please report if this works/does not work for you, that way I can get a good sample size to determine how effective this is.
Disclaimer: I have not tested this, I uploaded this image so testers could flash it and report if it works or not. If your device breaks/spontaneously combusts after flashing this, you accepted that risk.
Edit: A few people have reported this working, so it should be safe.
N2G47Z_4Cores.img, this image is based on the latest 7.1.2 firmware for the Nexus 5X, modified by me to only use 4 cores. 4 reported working, 2 reported not working.
To flash it: you must have an unlocked bootloader and fastboot on your PC. Boot your device into bootloader, and then run the command fastboot flash boot N2G47Z_4Cores.img Hopefully, your device will now boot up.
TWRP3_1_1_5X.img, modified to use only 4 cores, will get working TWRP on your device. Not tested yet
To flash, navigate to the folder where it is downloaded, make sure you have fastboot installed, and then run this command: fastboot flash recovery TWRP3_1_1_5X.img.
EX4_10_5X.zip, Elemental X kernel V4.10 for android 7.1.2, modified to use only 4 cores, I highly recommend you flash this, as EX kernel is faster, and you can overclock to the little cluster to make up for some speed. Not tested yet.
To flash, copy the zip to your device, then flash it in the modified TWRP, just go through the AROMA installer as usual. Changing the BIG cpu frequency in the installer will not change anything, as the cores are disabled.
Additional notes:
Root worked on my 6p by flashing the regular SuperSu zip just as normal. None tested for 5X yet
To improve performance slightly:
Disable animations in developer options, it helps a lot.
Overclock little cores with EX kernel, I have mine set to 1632 MHz and everything is working fine so far.
Set CPU governor to performance (or some aggressive governor), with the BIG cores disabled, the battery is already much better, so using a better performance governor shouldn't be a problem for battery life.
Doing a fresh flash of the firmware/factory reset can help a lot too.
Fast custom roms can also help.
Roms that me/other users have found working with this fix:
Pure Nexus worked well for me on the 6p, insane battery life and very little lag. If you are going to flash a rom, be sure to flash the modified EX kernel over it.
If you find a rom that works with this fix, tell me, and I'll put it here.
Credits:
@rchtk, his post here gave me the idea for how to modify the images.
@flar2, He built the Elemental X kernel for this device, I merely made a small modification to his kernel to use 4 cores. In no way am I trying to steal and/or discredit his work.
The TWRP development team, they built the TWRP recovery for this device, I merely made a small modification to their recovery to use 4 cores. In no way am I trying to steal and/or discredit their work.
Feel free to ask me for help, If you have a favorite ROM/Kernel that you want to use, tell me and i'll modify it to use 4 cores.
Please click thanks if I helped you, it means a lot to me

Well, I made a Fire HD 8 2018 custom ROM successfully but it went into boot loop that all it does show Amazon logo and I have a dmesg log attached and it was a kernel error, id like to mention @k4y0z to help me out to figure out what's wrong with the kernel. and i think that something went missing or it could not initialize. I copied the log from recovery.

The log you attached is from recovery, so it won't help finding issues with the ROM.
You can try to get /proc/last_kmsg to see if that shows anything.
Otherwise you may need to attach a serial console to UART.
Not sure if kernel-logging on UART is enabled in amonet-karnak though.
Alternatively you can try getting adb to work on your ROM to see if you can get a logcat and dmesg.
Make sure you build an eng-kernel so adb is enabled by default.
You may also need to add
Code:
sys.usb.ffs.aio_compat=1
to your default.prop

well, it doesn't boot up because it shuts down by itself. what happened is that, when I started it up and it shows the Amazon logo and shuts down. I can be able to boot into recovery. what I cant find is proc/last_kmsg. and how can i do the UART?

Look in /sys/fs/pstore/console-ramoops if there is no /proc/last_kmsg.
If it crashes, then hold the volume-button so it will reboot directly into recovery after crashing.
You should get the last kernel log there to see what caused the crash.
I don't know where the UART is on the karnak, since I don't have the device.
I don’t see that file in the recovery too. Well I reverted the changes from adding ambient capabilities to the kernel and. Removed all that by extracting a fresh kernel from amazon and then I had to rebuild the rom and added some overrides that you told me to add. If I had to I can use the prebuilt kernel as a fallback but what are the issues building with the prebuilt kernel

That's still the log from your recovery.
You need to get the device to reboot into recovery right after it crashes, so you can get the log from the crash.
Ok so I tried with prebuilt kernel, it stays on amazon logo and when I tried with the stock boot img with symlinks to fosinit and fossvc jars to linage os platform. But it still stays on amazon logo for the prebuilt and stock boot img. On the built kernel, it crashes and I can’t get logs. I’m trying to find a way to patch it with carliv’s image kitchen. But I don’t know what init files I can modify from my tree

I’m having issues booting with the custom rom with built kernel because it panics at startup and shuts down with built kernel. What methods I have tried is that I used the built kernel and it stops at amazon logo and shuts down. When I use prebuilt kernel, it stays on amazon logo. When I use its stock boot img from fire os with symbolic links it doesn’t boot and stays on amazon logo. I’m stuck at this process that it doesn’t boot up and I can’t get last_kmsg or ramoops. It’s making me struggle and I’d like @k4y0z to help me out and can fork my tree or authored it to help me what is wrong with my tree. I really can’t figure out but I am able to flash stock fire os back and it still has root access and twrp. I think the main cause of the problem is the verified boot or something. My tree is updated. https://github.com/488315/android_device_amazon_karnak. I tried adb devices on the boot process when it is on the amazon logo and it doesn’t show up on there. I tried to use default prop overrides and well it doesn’t show up too. Honestly I really don’t understand what is going on and I really need help to test this rom out. The kernel source for this device is incomplete and i have experience with building ROMs and this took me days than usual. I made a rom by using otapackage and it is block based. I’ve copied kernel modules and vendor files and some bin files and lib from fire os. When I made this rom, everything is included in this rom that are needed. I hope you guys have a good easter and I start school upcoming Monday and I will have a little time working on this rom and figuring it out to make it boot up. This device is not easy. Thanks

it boots into fastboot after installing custom ROM.
the files I have attached is:
ramdisk.zip rootdir from my device tree
boot.zip boot.img from lineage os before it was compiled.
there is something is preventing the ROM from booting up because I won't be able to get the logs.
if you want to see the fire HD 8's extracted boot image, it is posted on my GitHub here.
the problem I think it is an issue with init files.
thank you for your help. I know you dont have a fire hd 8 and i want this thing to boot into lineage.

you could start with cherry-picking commits to get it booting and then go from there

I don't know why your kernel doesn't boot, but the log shows you are missing some stuff as I have said before.
