Lg g3 kernel development help please - General Questions and Answers

I would really appreciate it if someone could help me to build a custom kernel for my lg g3 D855 I have done android development before so its nothing too new for me and I've had quite success in the past but these not many forums about this topic and especially up to date the trouble is either the code to install required packages in Linux don't work or I get random errors when building the kernel like a error 2 or 1 which there is nothing online about this error
So again I would really appreciate it if someone could lead me in the right direction or just some help anything is better then nothing
If you want to know what I'm trying to do then I want to build a custom kernel to overclock the phone but also help in performance because on full stock it gets too hot and constantly lags so I have install a custom ROM on the phone, the viper os ROM and hope to make a kernel to have a full custom phone and I can't use kernel apps like kernel adiutor because the setting don't save and there's no overclocking present after the reboot so that's why I want to make a kernel plus I would enjoy making one instead of getting one offline and most of the custom kernels for the D855 either bootloop the phone or puts it in download mode so there are many reasons why I want to make one and source.android.com seems awkward to follow along with but I have been doing dev stuff for a few months now so I know a fair bit about it just not as much as I would hope
Thanks for reading the post I know its a long one if you can help me it would be much appreciated

Flash kernel info needed

Hi experts,
I am currently using LG P500 with stock rom & kernel. I have never rooted rom before this. I have read somewhere from useful thread from this forum like here but am still not so sure and wondering if any problem will effect to the stock rom if I would like to flash kernel on my phone.
Most of the time I depend on my mobile phone such as alarm clock so just worried anything happen to the rom will cause me troublesome. ^^; I might flash rom in future but not now. So am interested about flashing kernel since people said that flash kernel will save battery life as well as overclock cpu. It would be glad if someone could explain to me or sharing link with great info.
Thanks a lot.
regards
android newbie
can i ask which software you are using?
you have to be careful when flashing kernels as some kernels may not be compatible with your specific software.
I would search for specific kernels for your software and if you have root, then make sure you have a backup kernel for the one you are about to flash and if any problems arise you can flash it back.
I use Kernel Update Utility 0.9 to flash different kernels to my device so maybe you can look into that once you have done your research

[Q] Roms compatible with Sharp FX plus? (ASD1)

Hello XDA,
I have bought a new android device for myself today, the Sharp FX Plus (Model: ADS1) and I've been browsing on the site to find some compatible roms; But no luck. I've used the forums before to successfully root and put a rom on my ASUS tablet with no issues, but this one is a mystery. Is there a thread with what roms are compatible with my phone or has nobody ever really looked into this phone? I've tried to google it with no luck, either. The phone is already rooted, I got that far, I just can't find any roms that are 'confirmed' compatible with it.
Thanks to whoever replies!
P.S. I'm slightly new to the whole custom rom thing - but I do somewhat understand the basics.
metoo!
I too have a sharp fx plus ads1. I have my phone rooted but am having no luck finding a custom rom. I understand it is kind of an entry level android and maybe out of date but it has all the capabilites I need. I also know enough to root my phone and install a rom but not good enough to actually create my own custom rom. Is there anyone that has the time and enjoys doing so that would help out with a custom rom for these phones? I found a page that mentioned updated to 3.2 with a new rom but there was no link for the rom so I'm thinkning it was a fake. Any help or suggestions would be appreciated.

EDIT: I posted in Misc Android Development section here, trying to put the information in a centralized area for any potential development on this device.
Recompiled the CM7 Kernel as a test using the device's config.gz, working on getting the CM7 source to go (its being tricky lol). I have a test CyanogenMod 6.1.2 ported from a Z71 that runs, as well as a modded stock 2.2.2 ROM. A "dirty-port" test of a Z71 CM7 rom boots with some mods (no radio, networking, etc..) - so there may be some hope for this lil thing!
Hope that helps

[Q] LG Volt

Hello! I have the Boost Mobile LG Volt and I am somewhat of a noob but smart enough to get it rooted on V4 using a rollback guide and towelroot. My problem is i hate the stock kernel and hate not having voltage control. Is there a flashable package that i can use to add voltage control and all of the other fun things that come with a custom kernel? Ive seen guides on porting roms to my device and they seem fairly simple since its just editing a zip with all custom stuff and leaving the sys files alone. Again the kernel!!! Ive tried flashing so many diffrent kernels but they all softbrick my phone
I love this phone. With root i have CPU settings so it lasts 3 days heavy use. I want more !!! Please help!!!
The stock kernel for this phone is available on githubhttps://github.com/chevanlol360/Kernel_LGE_X5
And from what im reading kernels must be device tailored?

yes sir they do. development is still in its infancy, there are people working on cyanogenmod right now, but they "JUST" got audio support, so you may want to wait a minute. There are a few custom roms available, just takes a lil google-fu.
Also you are very lucky to still have a working phone, careful with those kernels.

How to know which kernel to use ?

Hi guys
I have a old Moto g 1st gen (xt1032)
And been trying to get it running now but with not much luck.
The bootloader is unlocked and twrp installed and I installed a stock rom but it keep crashing about once or twice a day so I formatted everything and installed another rom can't remember the name right now but was comparable for my model .
And that won't get passed the black "android" screen
So been looking into it and people mention kernels but I haven't got a clue about them tbh so how can I tell which kernel I need or do they suit all ROMs
Can anyone suggest a matching kernel and rom
Cheers

I'm a lot really late but just a try a few different ROMs and make sure they say XT1032 or Falcon. ID crisis and Exodus are good 6.x ROM that are very stable. As for kernels, unless you really want to do some low level tweaks that require kernel intergretaion like Overclock, DT2W, CPU governer, etc., I wouldn't worry about it.
If you DO want a kernel I can't recommend ZERO Byte kernel by @BryanByteZ enough. Under volt/clock and over/volt clock, DT2W, it's got everything. Works great with Exodus

Sooo about that a good start is to flash the latest stock 5.1 then flash twrp and choose a 6.X rom (based on cm13) and that depends of your likes and wishes if you want a stable like rock rom i recommend AOSP+OMS 6.X/EXODUS/VanirAOSP if you want customizations there is Ressurection Remix,Dirty Unicorns and others, you just "need" to flash other kernel if you want more advanced features. This is just a recommendation for roms but lucky we have Kitkat,lollipop,marshmallow and nougat roms.
Thanks for the replies guys
I'm beginning to think I have a hardware problem on the phone.
I installed 3 versions of stock 5.1 on it last night
Eu,Brazil,and US I think they were they all install without errors
But only the Eu one boots up the other 2 stay on the "android" black screen.
The one that does boot us unstable though and crashes quite often .
That's why I thought about kernels and maybe it was that as I'm not sure if I need a certain one on my phone or any compatible one will do.

Well I already passed on that I change my bootloader to the one from BR stock 5.1 and now everything works fine. Try to change data partition to f2fs file system.

Learning to modify ROM/Kernel from Samsung Galaxy Tab Active SM-T365

Hey, i got a little project right here. It's important to say that i have knowledge in this kind of stuff but i never messed around with it except from installing roms on my phone.
I have to modify my self a ROM and kernel from android stock ROM (lets say Lollipop 5.1.1).
I need to do stuff like disabling the SD/Bluetooth /WI-FI in the kernel and comping a new ROM. Can someone here send me to the right places to learn how can i achieve this?
Thanks in advance.
