Yes, it's already out since a week or so.
I'm working on my kernel since then.
@xiaolongzi Do you have experience with tweaking MTK kernels? Are you planning on your own custom kernel?

this is my first time tweaking my own custom kernel。 I'm looking for some guide now！

i've started to look at the sources, MTK has a strange method of adding their part to a kernel tree Instead of using the normal parts of the directory structure, I found most drivers in /drivers/misc/mediatek/
Even the Machine part with its MTK specific frequency and voltage setting is there. The part where voltage and freqs are tweaked is not easy to follow but that's where freq tweaking could be done... https://github.com/tbalden/android_...ers/misc/mediatek/mach/mt6795/mt_cpufreq_64.c

Anyone know if it is possible to install this hero upgrade kernel onto 2.1v3 leaker rooted rom? And have it work. Or is the Sprint Hero kernel not compatible with Verizon Eris.
I thought both phones were basically the same phone but I could be wrong. If it is possible, is the kernel have anything to do with phone functionality at all? Or the kernel is basically the linux OS as their is a "Kernel upgrade" download link which states it can be applied to any Hero Rom located here:
http://android.teknologism.org/Download/
Any info or advice would be great. Thank you very much for taking the time to read my question.
you need to make a bunch of changes to the kernel first before you just start replacing the files or you could have a brick.

I C, so it would not be so easy then to do it?, Are any of the roms for the Eris using this kernel?
Thanks

why do you want that kernel? the eris kernel is just fine. plus we have overclocking working.

I need netfilter enabled to use droidwall. I am not on an unlimited data plan.
Here is the file you wanted.
It seems as if a lot of the reason people are hesitant to switch to froyo is the lack of custom kernels. custom kernels provide much better battery life as well as the ability to overclock as well as many other very useful features that create faster and more efficient operating system functions. From personal experience with froyo roms i have noticed the system to be quite slow compared to 2.1 and also i have noticed absolutely horrid battery life. We all know that these leaks may be far from complete but thats not to say that we shouldnt be making them better. It is obvious that Firon and noobnl have the correct information on this matter seeing as they have rooted all of the froyo releases inside of the zImage. If they were kind enough to share the information they have it would be very easy to either port our drivers to a i9000 froyo source or to use backported eclair libraries and use our current kernels. With this being said, I am very sure that this information could be the dealbreaker for froyo roms. With a good kernel comes a good functioning phone.
TO FIRON OR NOOBNL:
Please share your method of extracting the initramfs in order to quickly advance the development of froyo roms and to prolong the necessity for an updated source code
https://github.com/atinm/initramfs-utils
There's the tools to do it. I've done it successfully with the modding of the scripts about 5 times now. You cant technically do anything as far as overclock or battery life saving goes, as it isn't the source. It mainly allows you to edit the init.rc which can give you cutstom bootclasspath's and boot animations.
EDIT: LMAO, you think root is *just* in the kernel. >.< Root can also be put into the ROM itself...

THANKS A lot man
You have tested this on froyo kernels? And technically if we used a correct froyo initramfs combined with a 2.6.29 kernel with backported eclair libraries for certain hard/software aspects we should be able to acheive an eclair kernel on a froyo rom. Ive done it before on other phones
the jump from .29 to .32 is a massive one, but all the power to ya...

Ive done it on evos/nexus' and i can confirm that its been done on galaxy s phones. it may be a massive jump in version number and overall base code. but as far as android and our devices go it really hasnt changed too much. actually i can almost guarantee that it will boot just by swapping the kernel inside the zimage. but to get camera and other functions requiring updated drivers we would need older libraries. or we can just patch our board specific files onto a i9000 kernel. but hey. doubting is more fun than doing

hey i recently tried to extract the initramfs using that method and was unsuccessful. could anyone be kind enough to either post a download to a froyo initramfs or to give me simple instructions on how to extract it. ive tried putting the zimage in the folder and running extract-initramfs.sh and i get a 0kb cpio image
help

i have tried a few different ways to use this script being that i am new to Linux but i just recently experienced the same outcome as the above member. all help is appreciated btw
If you want better battery life editing the initram isn't going to do it.Your gonna need kernel source to play with to be able to do anything about battery life.

There should be only one way to use that script to extract.
./extract_initramfs.sh zImage
and here's the header from the repack script.
usage : ./repack.sh [kernel] [initramfs_direcotry] [kernel source dir] "title of build"
example : ./repack.sh /data/android/initramfs-utils/zImage /data/android/captivate-initramfs /data/android/linux-2.6.32 "title of build"
These are fairly simple shell scripts that only appear complicated because of the use of grep.
My first root, eng-off and all that I did through a guide on the internet that included kernel and rom for Leedroid.
Now I've installed AR3.6 and I'm wondering if I need to manually instal a new kernel or if the roms contain the appropriate kernels themselves.
a ROM always includes a kernel, but you can flash another one if you want to.
Yeah can't wait till theres a kernel for ARHD 4B4

I wouldn't recommend that for daily use though.. apparently it's buggy as.
i'm using this kernel since an hour now and haven't found any problems yet. battery life seems quite good also but i'll report back after a while
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

are there any overclocking kernels for mtk 8121 cpu ?
i would really love to see one, unfortunately i dont think that there is one out there because that cpu isnt used quite much until now.
Maybe somone has more info on that.

Nope. There is no source for that kernel as they don't believe in following the GPL.
