[Q] a question about Kernels

hello i am actually new to android, and i just fell in love with it,i am using
- Energy.Leo.23678.Sense2.5.Cookie.Aug.18
- mattc Leo + Froyo w/Sense RC1.5b
- radio 2.12
i have a noob question and i tried searching for an answer but i couldn't find one, i'd appreciate it if someone could direct me to a thread that answers my question
i read somewhere on the internet that i can download something called Kernel or a zimage and copy it to the android folder on my sd card so that i get a better performance from android on my phone, my question is what is a Kernel and how can i get it, does it really make any difference?
another question, i have somewhat a low call volume sometimes,so should i change the radio or would downloading a new kernel help me get a better call volume?
sorry if the questions are dumb but i am new to all this
thank you

The kernel is the software that allows the linux system (android or ubuntu) to communicate with the different hardware pieces of your device. The main step of android on the HD2 is development of the kernel. As the devs work on the kernel they release new versions. You probably read that updating your kernel would help performance.
I personally do not update the kernel myself. As the various builds are updated, the chefs will incorporate the latest kernel updates. As long as you are updating builds from time to time, you don't need to worry about updating your own kernel.

Hi,
I'm running mattcfroyosense1.6b-ppp this uses kernel michyprima 2.6.32.9 #70
There is an update for this kernel michyprima 2.6.32.9 #70 (r8)
How can I add this kernel to my Andriod? It is easy to put the Zimage file in my Android folder, but how do I add the .ko files?
Under the Shubcraft 1.4d install I could just add those files to the Android\root\system\lib\modules folder but in the mattcfroyosense1.6b-ppp I don't have these folders?
Thnx

You can just copy the kernel and overwrite the existing one in the android folder. Then you put the appropriate drivers in the matching folder of the root file in the android folder. To be completely honest With you, from my experience, you are much better off waiting for the chef to upgrade the build and use the included zimage(like mentioned above). You will have much less problems that way.
As far as the volume is concerned, buy louder volume hack from the market-it is a must have app and gives you alot more control over different aspects of the volume for various parts of the system.

Thnx for your reply.
Can I add the drivers to the rootfs.img then?

There is usually a root folder in the android folder. If you explore this folder (i.e. Root/system/lib/modules...), you will be able to drop the modules that come with the new zimage over to of the ones that are there'. Then when you start android it will load the modules you placed in the root folder.

android 1.6 to 2.x

change android 1.6 by adding bluetooth to transfer files and applications on the SD card ...
What do you think it is possible?

It's already possible.
Fyodor did with his 0.6.x rom series "a long time ago" an 1.6er AOSP Rom with apss2sd and Bluetooth File Transfer.
http://forum.xda-developers.com/showthread.php?t=644616
If you mean 1.6 with HTC Sense: It seems never possible to enable Bluetooth File Transfer unless we get the kernel sources from HTC.
Apps2sd is already enabled on some Sense Roms. Take a look in the Threads under Click Android Development

Google bluetooth voice dialing for chefs to (possibly?) cook in (apk attached)

So ive been looking and asking around about the bluetooth voice dialing thats supposed to be included in froyo builds and found something out, it seems that builds of froyo that came from htc had this apk ripped out for some reason, unlike builds leaked from google that had it and since it seems that the chefs here use builds of froyo from htc none of them had it..
so i did some digging and found the apk.. its an unsigned system apk and must either be pushed to a non squashed system/app folder or cooked in.
View attachment VoiceDialer.apk
this is the latest version from what i can tell/find.
(sorry if this might not be the best place to post this, but i thought it would be the most noticeable for the chefs)

just got this working on mdeejays froyo revolution 2.3.. it seems that due to permissions needed it has to be either cooked in or pushed to the system/app/ folder, it works with that build due to it being unsquashed, so yes, this works perfectly.
and big tip, change the language under settings/voice input & output/voice recognizer settings/ to your correct locale, it helps alot.

How do I record calls (Mod)

I've seen the thread floating around before I got the phone and can't find it for the life of me now.
I know there's a hack that allows me to record my own phone calls, from what i've been reading on an i9000 forum its done in the form of a modified apk file.
Can anyone point me in the right direction on how I can get this set up on my S II
Don't know if you need to know this info but im running
Firmware - DarkyRom2 XXKH3 Base R2
Kernel Version - 2.6.35.11 - [email protected] #26
Android Version - 2.3.4

Isn't it part of the Batista Rom? you could extract the dialer from it.
Some people use "Call recorder" (icon: green android) and reports it works fine.

Thanks for the hint, downloading the batista rom now, Its weird, as simple as it is it never occured to me that I could mix and match contents from different roms, I think its time for me to do some experimenting now, so what I can concuct.
And remember children if you decide to do the same nandroid that sh*t first

BLUETOOTH!!

I have been looking for some help for what seems like an eternity now.
In Tytung's ROM : NexusHD2-Gingerbread v3.2a (GWK74)(Android 2.3.7)
with the r_14 update kernel with callrec, all audio output (Winamp,Proamp,Youtube, TuneIn, Pandora, etc.) is streamed thru bluetooth without using and apps or tricks.
I have tried an endless amount of newer Roms including ICS and now Jellybean and I cannot duplicate this feature.
The rom only streams the native audio player only, if it even does it at all.
My question is, is there a way to copy a file from the Gingerbread rom to the newer rom to make this work or is it in the
kernel itself??
I like flashing new roms, but always go back to Gingerbread for the streaming audio through bluetooth.
Can anyone shed some light over here before I pull ALL of my hair out???
