Kernel Downgrading Question.

I'm using King's #11 kernel with Fresh's latest. My question is if I flash to Cyanogen 6.1 (when it's released) does the kernel follow to that ROM? I don't want to flash another ROM and run into problems.
Sent while sitting on the toilet.

most roms include there own kernel which will over write any existing kernel you have. CM 6.1 I am positive will have a kernel package with it.
It is safe to assume you wont have any issues

Also ... be sure to do a nand back up before flashing the new rom. That will preserve,, not only your rom, but your kernel as well ... just in case you want to return to it.

[Q] Overclock Question

Hi. I have a S-Off, perm rooted T-Mobile G2 and would like to use this method to overclock my phone:http://theunlockr.com/2010/12/14/ho...ted-s-off-t-mobile-mytouch-4g-or-t-mobile-g2/
Q1: Is it recommended?
Q2: It requires me to use a custom ROM, which I do not want to. Is there an "original" rom that has ADB Remounting which I can use instead?
Thanks in advance.

I'm not able to view the method you've posted from where I'm at right now, but I can tell you that the most stable, "permanent" overclocking experience I ever found when on stock rom is CM's BaconBits (which includes an overclocking kernel among other things) used in conjunction with SetCPU.
you will need Clockworkmod recovery installed on your phone to flash the baconbits zip. I'm guessing you already have this - if not, you just need to install Rom Manager and you will be able to flash cwm recovery through the app.
from there, all you need to do is install setCPU (it's free here on XDA - just search for it) and use it to set your clock speeds.
easy as pie method for overclocking on stock rom.. and my guess is that it will be more stable than anything you get from theunlockr - it seems to me most of their tutorials are a bit outdated for the vision.

Download ROM Manager and use it to download Pershoot's kernel.

you can try pershoot's as well, but I will say that it did not play nice with my G2's stock froyo rom. this was a few months ago though so maybe there has been a remedy and it's working swimmingly now.
if you get pershoot's kernel to work, I would recommend it over baconbits as pershoot is constantly updating and improving it.

Just to clarify.... You need to change your kernel to overclock not your rom. A lot of roms include an overclocked kernel but that doesnt mean you cant flash a kernel with your stock rom. Make sure you set up a heat profile with setcpu so you dont fry your phone.

Thanks guys for all your help.
I went with a more simple solution, and flashed CM7.
Now it looks as nice as the original and has 1.5GHz overclock.
Do I need to set heat profiles for CM7 or the stable release will take care of it?

kernel/modules repacking?

Hi,
I've been an avid guest on this forum for about a week now. I got the HTC One X international version running rd-miui 2.8.3 CM9 version and used this awesome forum to learn all the unlocking bootloader, rooting, and custom rom business all pretty fast. I'm trying to pick up kerneling but need some help.
1. it's my understanding that the kernel resides within the boot.img?
2. what exactly are modules (that sometimes comes along with certain kernels??) Is it absolutely necessary to install the modules in recovery after flashing the boot.img in fastboot?
3. I want to use the ncx-v.0.65 kernel with the rd-miui 2.8.3 CM9 rom but there isn't a repack for this rom. I found a nice tutorial of how to do this in windows but still a little confused on some things.
to repack the ncx-v.0.65 kernel for rd-miui 2.8.3 CM9 version --- can I just unpack my rom's boot.img, then replace the boot.img-kernel with the boot.img-kernel inside the boot.img of the ncx-v.0.65. Then repack and flash the new boot.img (with the ncx-v.0.65's boot.img-kernel inside)??
would I need modules???
4. is there a tool/app to easily repack kernels for other roms?
5. what's the best kernel out there for htc one x? Does that depend on which rom you're running? I'm mainly trying to improve my battery life but wouldn't want to sacrifice stability for it.
Thanks for your help guys.
PS. what does "OP" stand for?
Also, is anyone else experiencing problems with the volume rocker wake on RD-MIUI 2.8.3?? It would work for like 5-10 sec after phone sleeps but anytime after that it won't work...then sometimes it would work after a long standby/sleep.

1: yes.
2: They help the kernel work. They are necessary.
3: You need to flash the modules from the thread and repack the kernel, using
4: this
5: There isn't really a 'best' all round. You'd have to try each kernel and choose which one you want.
PS: OP stands for original post or original poster.

so after I repack the boot.img with the kernal I want then flash it in fastboot..then I still gotta install the modules in recovery?
just use the module from the OP even though it wasn't been repacked for my specific rom? (Do modules need repacking??)

i noticed that sometimes (not always) the module .zip contains a folder named "kernel" with a boot.img inside it.]
is that kernel folder necessary? Do the modules need to be repacked?

[Q] Kernel choices with UCLH9

I've just flashed to UCLH9 from LG8 however KToonsez's kernel doesn't support UCLH9 (My Wifi didn't work at least). Currently I'm running the stock kernel and modem, but are there any choices for kernels now that I'm on UCLH9? Or should I wait for KToon to release a version that will support it?

U will have to wait just like me lol....altho i did find his 9-12 to work on i8 but the screen flashed like mad had to disabke overlays. So i flashed back to stock

ktoonsez's TW kernel works fine with LH9. Just make sure you flash the kernel after you flash the OTA or ROM. I'm using it now with wifi with no problems.
In case you're interested, the kernel has two pieces: the kernel image which lives in its own partition and the kernel modules. These live in /system/lib/modules. When you flash a ROM it will typically wipe /system. Some ROMs include kernel modules and some don't, but things like wifi won't work unless you have the kernel modules that go with the kernel image.
So, if you're running a custom kernel, you should always reflash it after flashing a ROM to make sure you have the right kernel modules. Especially if wifi doesn't work.

Wow! That's extremely informative, I had no idea that's how the kernel actually fit together. I'm going to reflash KToon's kernel in that case and see how it works. Thanks for the info and advice!

[Q] understand kernel repacking operation

Ok guys, I've been around for a while and now I need some help for kernel repack, please...
well...was trying to get the aosp build work with ncx kernel...
so I flashed the kernel....the rom...modules and gapps...and it stucked at bootlogo with sw buttons light on
then...I tried a repacking operation with one-click tool...I repacked the ncx kernel with the rom's ramdisk (from the boot.img in the rom) and ncx modules...reflashed everything, result: no connection, like if I haven't flashed the modules...
now, I heard that repacking's purpose is to combine custom kernel with rom's ramdisk, for compatibility problems...and the modules of course...
why doesn't work?? :/

You can't go wrong with that tool.
Just make sure to first flash the ROM and then the modules.
