Question about Kernel. - Desire HD General

Hello, I just rooted & S-off my Desire HD and trying different ROMs like RCMixHD and CM7. It has been great fun!
I understand ROM is like the OS of my phone, Radio is the part for network&call and RIL is like the bridge to connect ROM and Radio.
But what about Kernel? Is it like some kind of skin or what? Is Kernel independent to ROM? I mean can I flash any Kernel into any ROM or is it specifically for 1 ROM only?
And finally how can I flash a Kernel? Can I just flash it in ClockworkMod recovery / ROM Manager like flashing a ROM?
Thank you very much
Terence

Kernel is the source. Think of it a bit like DOS was to windows when windows was still DOS based. The ROM is the pretty graphical stuff built on the Kernel (very very very simplistic).
Pretty much flash any Kernel but as a rule most ROM's will use the most up to date. Then there are custom Kernels that have added goodies in them like over-clocking. Again, you can flash these over just about any recent ROM you find.

You can use Kernel Manager App or flash them in CWM Recovery. Could probably use ROM Manager but for Kernels I prefer to use recovery.

[Q] confused about kernal

I was wondering about the overclocking kernal for cm7. just how do i put it in. Do I have to do that when I first install or can I add it later. also does it really help. I mean is the difference really noticeable or not at all. I am still deciding if I should do it or not.
Kernels are flashed through ClockworkMod and can be flash anytime after you flash a rom. If you use the search bar you can easily find what particular kernel works for your setup.
OK, I think I found the right one but I was also wondering if I could install it when I first installed cm7. When I installed it I saw that it was searching for the kernel and for gapps but didn't find the n and skipped it. Could I install it then

CM7 has the ability to be overclocked as it sets.
settings > CM settings > performance > CPU settings.
just be extremely careful when Overclocking devices. it can takes it's toll in the long run.
and the g/apps are not kernel dependent they are ROM dependent.
OK but what do you mean by gapps are not kernal dependant

On *UNIX based devices. They have a section of the firmware called the "kernel". The kernel accepts the coding, binary and scripts from the RAM/ROM and tells the hardware how to act, what to do, and when to do it.
The g/apps have nothing to do with the kernel.
The g/apps are Google's property and cannot be included in AOSP based ROMs. Those ROMs are developed from Google's code. And developers do not have the ability to add those at will. So we must flash them after/prior (depending on he ROM) to get the Google Apps.
YES! DO IT!
for me its like day and night, it so much smoother with dals OC kernel. and yes you can flash the OC kernel any time. you can flash cm7 rc1 then OC kernel in the same boot. or you can first install cm7 to check it out for a while and then later flash the new kernel. if you planning to flash dal's 6/18 kernel, make sure to get his app NC Tweaks.

thanks. What I want to know is how to flash it. do I do it the same way as gapps( have wifi and reboot in recovery mode) or is there a different way?

You place the over clock zip file in the root of your sd card and flash it through cwm like you would a rom or gapps. So for example you would flash cm7 then gapps then the overclock kernel.
Not to Jack this thread, but I want to update from cm7 old kernel to New nightly build. Does the new kernel flash with the nightly?

When you move from stable cm7 to cm7 nightly the new kernel is included. However the included kernel is overclockable only to 975mhz. If you want a higher clock speed you'll have to use dals 6182011 kernel, up to 1200mhz.
whats is cmw?

it's actually CWM.
ClockWork Manager
basically boot into recovery then flash.
OK. but this may be a stupid question but will the cm7 kernal work with the stable version7.0.3 because that is what I have.

I'm not following you cannot use just a Cyanogen(mod) kernel. They are built into their ROMs.

sorry, but no. dal's 6/18 OC kernel will not work with 7.0.3....

Ok thanks anyway. do you know when the kernal will work with a stable version

The latest nightly should be considered stable. It is in release candidate stable for the next stable build. The next stable build should be released in the next couple of days.

There is a Clockwork ROM Manager and a ClockworkMod Recovery image.
Together they are known as "CWM" Since one is a recovery and the other is a ROM manager.

convert hd2 to android

hi guys got one of these phones and looking to convert it to android.
i used to have a zte blade which i used custom roms on.
having looked around on the net there appears to be a lot of threads and ways of doing it, through sd card and through the nand.
just a quick question what is the best way to convert ?
thanks in advance
nand.
you just need to install hspl, and magldr.
then, flash over clockwork mod to flash roms.
you can see it done on youtube.

'Is there a more stable ROM out there'
Read the ROM title, it's a BETA!! Of course there are more stable ROMs out there, this one isn't even for daily use (in my opinion). Firstly see this guide for how to flash, then as for ROMs you may want to try a CM7 ROM, these are fast and stable.
if you want safety (keep a warranty if you have one), ability to go back to winmo in a snap, and ease youre safest bet is SD rom!
if you are wanting to turn this bad boy into more of a NATIVE android/WP7 device get to flashing that NAND!
there are plenty of ROCK solid android roms available, however, ANY droid 4.x (ICS) roms at this point arent quite your solid everyday drivers. they (the AMAZING devs here) are still working out bugs with usb storage and camera conflicts. so if neither one of those are needed then go for it lol :-D
whatever method you choose (SD/NAND) I wish you good luck and a simple reminder ... READ, READ, READ!!!

Good choice of rom
You would have to flash a new Kernel which supports higher O/C frequencies. I personally haven't found much difference after doing this, but Dorimanx's Kernel supports up to 1.61GHz overclock
To flash, just enter CWM and flash .zip folder
thanks bud.
just installed the AmeriCanAndroid and all is well its a very snappy rom
but i cant get into cwm to do a backup ?
says its not there in ad recovery ?

I would recommend not doing that, as you may get into the habit of Task29ing too much. this could cause problems (search bad blocks on NAND) in future. You could probably get away with just reflashing CWM if you followed the rest of the steps correctly

[Q] Help with ROM

As you guys may know, I recently downloaded the latest matriz mod by mathkid...do you think I need a ROM installed to use at its full potential? If so, which ROM should I install and do I have to re-install the kernel?
1. U don't have to flash another ROM if you are on stock ROM or another AOSP ROM
2. Feel free to flash any ROM u want all AOSP based Ron's should work with this kernel.
3. If u flash another ROM u have to flash the kernel again because the stock kernel of the ROM will be flashed as well.
BTW. Post this kind of questions into the Q&A forum for the N4.

So I'm on Stock ROM right now. I don't need to redo the installation process and just flash it at will? Didn't know you can flash multiple roms too...
what roms do you guys recommend with the most with matr1x kernel?

matrix is not a rom, it is a kernel. all roms include kernels, or your phone would never work. all you do is flash matrix over what you have now, and itll replace your current kernel with matrix. that is all, do not over think it, do not make it more complicated then it actually is. and no, no one can tell you what rom to run, it is only your personal choice and no one elses. there are roms in the development section, read their threads, then you decide.

I know matrix is a kernel, I'm saying which one would be the most appropriate to go with it. One more question: Whenever there's an android update and I have flashed a Rom and Kernel, do I have to redo the flashing process again? ex. Android 4.4.4

Thank you bro. I previously used an MTK device and i know about flashing and rooting. But never used custom kernel. Can we use custom rom without any custom kernel? or is it necessary that i have to flash custom kernel for every custom rom?. Also give me links of bugless roms for our device?

You flash the kernel just like the rom,I would flash the rom, then open gapps or bean gapps. Next I would flash supersu which you can find by doing a search of the forum, wipe dalvik cache, start finish setup then flash squid kernel. Also download kernel auditor from play store to get the most out of squid kernel. Helix kernel is another alternative based off squid kernel. Both squid and Helix allow you to change several options to improve battery life and performance.

if you're talking about a500w, you can take any rom (based on stock at least) and replace your boot.img in rom zip.
