So, I don't understand X8's situation upon custom kernels... did we crack the necessary permissions to install kernels?
We need to bypass bootloader. When it will be done we can use custom kernels
Ye. I heard that on X10 that has been achieved, and, therefore, it will soon be done for X8 as well...
Also heard that custom kernels are not yet universal... they need to be tweaked for each individual ROM... but I read that devs are almost getting it.
Also, what are the advantages of a custom kernel? Can we edit, for example, drivers? (No need for doixanh's MDDI or Gesture modules???) Native OC? (No need for OC modules???) What else?

Hello Together,
Now after Alpharev-X has done such great work and open new possibilities for
us, i am thinking about rooting my wildfire for the purpose of overclocking.
Im happy with my stock rom, but would like to experience some
performance enhancement. But there are some things im not really sure about.
The first Question i have is:
Is it really worth to root the phone regarding to the enhancement of the performance that can be reached with a overclocked stock rom.?
(Im wishing to have some smoother menue performance while using some apps like k9 and other applications of daily usage, scrolling through contats etc,...... not gaming at all!)
The second Question i have is:
I have read about some users having problem after installing a custom kernel, like missing some functions like wifi or usb-problems and so on) Is there any user-experiance about which kernel is properly working with the stock rom mentioned in the title?
So it would be great if some user could post their experiance with overclocking a stock rom and which kernel they prefer and have tested.
Thanks in advance for all comments

If you don't want to switch to a custom ROM there's a really cool app called 'SetCPU for Root Users' which, after rooting your phone, lets you overclock your CPU as you wish. A word of advice, go easy on the Max CPU frequency!
Alpharevx doesn't root your phone, it just sets the S flag on your HBOOT to OFF. To root your phone take a look at this :http://forum.xda-developers.com/showthread.php?t=1130044

It'll still need a Custom Kernel.
OP, You can go for Arco's nFinity kernel modified by johseen for Sense ROMs (Listed first under Kernels List in the Wildfire Index Thread). Overclocking does improve general performance, but, its the gain is certainly not as much as the overclock % suggests,
to overclock, you´ll need to change the kernel, and to change the kernel, you must have installed clockworkmod , and to install it, you have to root your phone
i've found just enough answers about this to confuse me
I understand the difference between a kernel and a ROM, what i don't understand is compatibility. Unless there's an epic ROM (eg, CM) i usually prefer to stay rooted, but bloat free. but I've never had an android device that i can go as hack-crazy as i intend to do with my soon-to-be-arriving a500, and i'm planning on at least exploring some more in depth hacks.
So, my question is, how cross compatible are kernels. I know they're often designed for specific ROMS, i also know there are at least some instances where you can use one kernel across multiple ROMS, and that in some cases one ROM can accept multiple kernels. But... i guess i'm just looking for clarification. How exactly does ROM/kernel compatibility work? can i swap out the stock kernel for the fastest kernel, or is it more complicated than that?
thanks in advance guys.

Most kernel threads will state which ROMs they're compatible with. Stick with what the OP of the thread states, and you should be OK, with exception of a few minor bugs here and there now and then.
I've been flashing different roms but I don't flash kernels can you guys tell me what flashing one of them will do?

What most use them for is to (overclock) their tabs and other features. Make sure you get the one for the rom you have installed.
Kernels are the simple codes written to utilize the hardware. They make available all the functions of hardware with system calls. Some of the kernels are also called micro kernels as they use very little codes to use all the functions of hardware and are thus very small in size. But coding becomes a little bit typical. Well simply, when you are changing your rom most of the time your kernel also change as different dev's use different kernel for there rom. You need not to worry to change kernel if you dont know much about it. Kernel are also responsible for increasing the speed of your tab as they change the way hardware is implemented.
One very good outcome of changing kernel you must have noted is that of overclocking.
Try to use the kernel which is stable.
I want to know if I need to install a custom rom or a custom kernel or a combination of both so that I can overclock my phone(1ghz single core). Please help. Why is everybody so silent here, so unwilling to answer a simple question as this. My fourth post of the same question.

Any custom ROM that comes packaged with an included kernel should allow you to overclock. AFAIK the oveclocking capability lies within the kernel (at least with Xperias this is the case) . At the least, a stock ROM with a custom kernel and a CPU/Performance app will give you overclocking options.
My suggestion though is to get a ROM like PAC, that comes with a kernel and the needed app to manage your CPU settings.

That is not fully correct.
Most PAC builds use the stock CM kernel. Our ROM offers performance settings to manage that, but they generally do not allow overclocking.
Some of us have additional builds with performance kernels built in. Not all of us though.
Your best approach would be to install PAC for your device then check your devices XDA thread for a popular performance kernel and flash that afterwords. The performance control will see the new CPU settings and you will then be able to configure it as you need.
DL an oc app, like CPU tuner or whatever..

Yes, you need a kernel with overclock support .
On Gs2 I use PAC and dorimanx kernel
On your phone you need to search for kernels and roms for your model

Hi, just a quick question
Kernels come WITH the Rom? right?
...like if I flash a custom rom...no need to worry about the Kernel?
do I need a specific Kernel for a specific rom to run properly?
I've been flashing roms since ages but still dont know a thing about Kernels
thanks

Yes, kernels come with the ROM. If a ROM doesn't have a kernel, it won't boot (hence the name "kernel").
Usually, the most "proper" kernel for your ROM would be the one that came with it. Although sometimes, flashing a different kernel can improve performance/responsiveness/battery ..etc .... But it can also break things if you don't know what you're doing. It's always a good idea to make a backup before doing something.
Have fun.
