Gents,
I need your help about "kernel", as I know when installing Android I need the folder named Android and the data.img.
But the kernel what is that?
Thanks for reading and more for helping.
The kernel is the core of the Android OS. Windows too runs on a kernel. Every build already includes one, and usually the most up-to-date or stable version, so you shouldn't have to worry about it, unless you want to update your kernel some time in the future.
I've been running Android for several months now and I've not updated the kernel once.
Still there is somthing to say
First I want to thank you for giving me some of your time.
The answer is clear, but why there is update always (now is 8.6)?
and what the kernel is including, is it the same of Android folder?
I hope I will find some more time.
Check out here for a bunch of explanations of terms that are commonly used around here

The reason that the kernels are updated alot is that the people who build the kernels find flaws in them through testing them, and through the feedback they recieve here on XDA.
Then they work to try and find ways to fix those flaws. Sometimes in fixing one flaw, a new one emerges. Generally it is a good idea to use the latest version of whatever kernel came with the build.
I have the US version of the Atrix and I'm rooted/bootloader unlocked running the CM7 Ba2tf rom. Any ideas on why available RAM is only showing about 400 mb of 800? It usually stays around 350-400. Can this be fixed? Does it need to be fixed?
You should have read all the instructions carefully before start unlocking the phone. here's the fix
Code:

More simple explanation?
I'm probably confused, but it seems as if that post is referencing the Orange/Bell version of motoblur. Since I'm on CM7, does it still apply? Also, everyone seems to be having side effects (broken wifi or data). And finally, does this fix actually increase performance?
A simpler explanation for me would be greatly appreciated
I just flashed my Atrix with CM7 as well and am noticing the same RAM usage as you. How do you know that its supposed to be a lot less? Seems OK to me?
Chris
Hi,
The reason it is showing ~400MB of ram is that you installed an unlocked bootloader that was leaked, it is different than the ATI version and it doesn't pass along the information about the second bank of memory installed. I did up a patch for that, search in dev for Gobstopper and/or ramfix. The patch adds a bit to the cmdline of the boot partition, so it doesn't require a specific kernel or ramdisk and should work fine with CM7 as is. Or it may not, it worked for me and my phone.
Cheers!
I can't find the ramfix thread, and the gobstopper just looks like another ROM. Could you give me the specific steps you used on your phone that worked?
EDIT: Not to mention search doesn't work now…
Hello guys, i just have a (few) question(s)
So, last week i installed Google Edition Andriod Kitkat 4.4.4 on my galaxy S4 I9505.
This rom is till now, still amazing, fast and better than touchwiz in any way. But i can't seem to find on the internet how and which version of xposed framework i need to install, since it is per model (i think?) which model do i choose?
since i have a Galay S4 but my rom is not from a galaxy S4, i get confused which one i have to install.
Some links to downloads would be great!
Thanks in advance

Hi mate
Basically it works in any android 4.0 + base rom device see from one of his threads
For which devices/ROMs does it work?
I develop the Xposed framework based on the AOSP sources. I'm personally using CM10.2 on an I9100 (Samsung Galaxy S2, bought in Germany). Basically, it should work on any phone which with a ROM based on Android 4.0 or later and an ARM or x86 processor (this is the processor architecture, almost all smart phones and tablets have either of those). Exceptions might be ROMs which are different from the original Android code in some very internal, central code parts (which don't need to be touched for most theming and enhancement modifications). But this is related to the ROM, not the phone itself.
The modules target higher-level code, so they are more likely to be incompatible with your ROM. Basically, the question is whether the methods and resources which the module modifies are similar on your ROM and on the developer's ROM. Let's say a module needs to modify the result of a certain method call. For this, it needs to specify the exact name and parameters that identify that method. If the in your ROM, an additional parameter has been added, the module can't find the method anymore and won't work. If the method can still be found, it will probably work (unless the rest of the app/ROM has changed too much).
There is not definite answer whether it will work. Just try it (of course, making a nandroid backup before is never a bad idea). If it doesn't work, just disable the module. You might want to inform the module developer (not me!) about this fact and provide details (e.g. a logcat and/or the content of /data/data/de.robv.android.xposed.installer/log/debug.log).
Try with latest 2.6.1

Any time mate.
I still use my Nexus 4 happily and recently started modding the kernel a bit.
This led me to the question in the first hand, because it is possible to upgrade minor versions (3.4.0 -> 3.4.105)
The thing is, N4 uses google_msm 3.4 sources
shamu is pretty new, uses google_msm too but 3.10
I've tried by bluntly downloading shamu's kernel source, placing mako_defconfig in arch/arm/configs and updating the defconfig with make menuconfig.
As expected didn't work out, but i'm just a little modder cherry-picking stuff i'd like to have, so in reality i have no clue how to archieve that, or if it is even possible with some modifications.
I've also tried with the standard 3.18 Linux kernel too before, but got the same expected result.
Did someone actually tried this and got a bit further, is this something simply not posiible or too much work to get it going?
Hello, I'd like to find a custom rom that doesn't have any useless power wasting phone slowing functions, But instead focuses on performance, Any one you recommend?
Please refrain from replying with unhelpful and useless answers

Try not to word it like that next time, it comes across as ignorant and disrespectful even though you may not mean it that way. People will be tempted to write unhelpful and useless answers as a result. useless power wasting phone slowing functions - very subjective and vague. Please refrain from replying with unhelpful and useless answers - don't have this attitude when you're asking for help.
Try something like " I'd like to find a custom ROM that has a focus on performance. I use my phone for x , y and z. I am/ am not concerned about battery life, but I'd like it to last a whole day. I prefer an AOSP/Touchwiz based ROM. I would appreciate if anyone could give me any ROM suggestions"
Now that we got that out of the way. There is also a fair bit of info that could assist in finding the best ROM for you. What do you use your phone for? games? photos? messaging? internet browsing? any particular apps you use often? Is battery life important to you? Do you prefer AOSP or Touchwiz? what have you tried? how did that work out for you? What phone model?
Most ROMS come with these "useless power wasting phone slowing functions" because the developer wants it to work for a variety of people who all use their phone differently. If you don't like an app/ function, uninstall it. There are also ROMs that come with nothing much + AROMA to chuck in apps you want. e.g. Superlite, Xtrestolite
In absence of the extra details, I can suggest Superlite or Xtrestolite (lollipop, no longer supported - but I use and its great ) for Touchwiz. AOSP Roms such as Lineage, CrDdroid, Resurrection Remix may suit you too, but they have disadvantages - mainly battery, some sensors and camera.
I hope this helped. Pls provide more details if you would like suggestions tailored to your needs.

You're right, I' apologize.
I have a galaxy S5 g906s, i'd like to use it to play games, And i have no idea what you mean by touchwiz or aosp haha, And battery life isn't important to me as long as i squeeze out any potential performance increase

AOSP - based on stock android e.g. pixel, nexus
touchwiz, based on samsung's software e.g. the stock one your phone came with
I am not too familiar with that model. It is an uncommon model so there is not as much development being done on it as far as I understand. I have done some research for you and found:
A page that discusses ROMs and kernels for korean models.
https://forum.xda-developers.com/galaxy-s5/general/korean-s5-900slk-custom-roms-t3253136
The ROMs are all ports and some AOSP here. I wouldn't go any of them if I wanted performance, other than maybe cyanogenmod TBH.
a link to TWRP, which will help you flash the custom ROM/ kernel you choose.
https://forum.xda-developers.com/galaxy-s5/development/recovery-twrp-recovery-v2-8-7-0-t3199011
If I were you and wanted best performance and dont care about battery life, given the poor development scene, I would keep the stock ROM, root and flash a custom kernel, then overclock and adjust voltages accordingly. Hispasian kernel is that one they have there, no idea about its features. It is an android 5.1 kernel, so make sure you are on that firmware when you flash.
Any questions, let us know. And if anyone is more familiar with this model, feel free to chime in.

Okay so, I have my phone rooted, And i spent the whole day trying to flash my device with a custom recovery, I tried TWRP and some other stuff, I flashed it with Odin on my computer But when i try to boot into recovery mode, The phone restarts normally, Or when i download CWM and select the TWRP recovery and tap on boot into recovery mode, The phone just loops, I had to go into download mode and flash it again for it to start normally.
Given that, Can you tell me what a kernel is and how to flash it?
Can you also tell me how to manually do this overclock thing and adjusting voltages? I have no idea how to, And my various expeditions into installing custom rom into my phone has been driving my nuts crazy, I found out about all of these when i stumbled upon bloatwares btw, Which might be the reason why all of my S3's and note 2 were having crap performance a few months after the purchase
And thanks for your time

"But when i try to boot into recovery mode, The phone restarts normally" => you are probably doing it wrong then, even if TWRP patch doesn't work, you still should boot to the stock recovery. For all the models that I've tried, its been the same, I have linked a video for S7 edge, should be the same for your model (this video shows pretty much how I would go about TWRP). I couldnt find one for S5.
Just odin flash, making sure that reboot is not ticked. Then boot into download mode (volume up + home + power at the same time. press and hold in that order (its just easier) and hold down all until phone boots).

I've never used CWM in my life lol. So I wont try to give advice on that.
A kernel controls the CPU, voltage, GPU, memory etc. like pretty much everything. As far as I understand, stock is not ideal or impossible to overclock. The custom kernel will allow you to overclock. Once you have twrp then you can flash a kernel with the install button on the menu. ensure that cache and davlik/ART cache is wiped (pre or post install, doesnt really matter). Do not forget to backup EFS at the very least (in the backup menu). The kernel page will tell you the developer's recommended installation method though. Make sure you look up the kernel features, not all kernels allow overclock. Make sure the kernel is compatible with your model and version of android.
I personally do not recommend overclock as it may cause system instabilities. But that may be because I dont play games on phone and dont require that much performance. I'm only supplying you with knowledge. The general disclaimer is that I am not responsible if something goes wrong and your phone bricks, explodes etc. I never made you do these mods. Phones are usually pretty resilient to overclock though.
If you need any kernel or TWRP help, I'm happy to help but bear in mind that I would not have used any of the kernels for your model nor have I used TWRP for your model. TWRP and kernels are pretty consistent across models as far as I know though.
Happy flashing!
