When Flashing a ROM, kernel needed? - Epic 4G Q&A, Help & Troubleshooting

Since this morning, this will be my first flash, do you have to use a KERNEL when flashing? For example. if I go with(most likely) the Syndicate Rom(I see that the twilight kernel) is included. Can I use a different ROM if I want? Basically, does all ROMS have Kernels that come with it? THANKS!

Yeah,ROMs will come with kernels almost always... They can be switched,but beware,Twilight has root built-in,so SyndicateROM and my ROM dont have the files needed to support root on an un-rooted kernel.

[Q] Are these Roms and Kernels Compatible with DI18?

Ok guys im on android 2.1.1 DI18. I was wondering If i can flash these roms and kernels to my phone? Like are they compatible with my DI18?
I'm interested in this Rom & Kernel...

I just want to know if those above kernel and roms would work together? The kernels are recommended for the roms!
Thank You!
Could Someone help me! Im a noob at this. This will be my first time! Please Help!
Simply put, no. You need to have the dk28 modem for your first option and the eb13 modem for your second option. So you will have to either upgrade to the leaked dk28 or "official" eb13 to do one or the other first. Just search the site here, im on my phone so i cant link them for you.

You can't.use an android 2.2 kernel and rom on eclair. You have to stay on the same build. Why don't you use Odin to upgrade to eb13 then you can have that rom. And personally o wouldn't use that kernel with that rom. That rom has its own kernel

[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?

[Q] Is it possible to CHANGE KERNEL on stock htc rom 2.3.5 rooted by nitro

Hi all:
I´ve been reading hundreds of post regarding roms and kernels and Im not sure if I can change the kernel to put for example unity v9 or 10 without changing sotck rom.
I want o OC and 2 way recording but I dont want to change rom.
Is this possible??
Thanks in advance.
No problems changing the kernel on a stock rooted ROM.
Just remember you're looking for a sense kernel, not an AOSP kernel.
Flashable from recovery.
Sent from The App that Time Forgot.
I believe you can because i also own I9001 and since there's no proper custom rom for it when the kernel was available, people had flashed that to get init.d support but i'm no dev. If you have clockwork then you can try flashing it if you want...because i never heard of flashing a kernel alone but with the custom rom.
Thanks for the answers.
Now knowing that I can do it via clockwork.
What would be a good kernel?
I was thinking in Unity v9
Thank you
Its really down to personal preference, and how the kernel runs on your DHD.
Last time I was running sense I used Lees, but I don't know if he has call recording.
PS 4ext touch recovery is really nice.

Ok thanks jagdave.
Hehe and thanks for the suggestion.

Need help picking a ROM / kernel

I've rooted my HTC Evo 4G (not LTE). I tried to set up a swap partition and learned that i need a different kernel. Regardless of whether or not i use swap memory, I'd still like to find a good ROM/Kernel. I'd love ICS, but they all say that 4g and the camera doesn't work yet. I have trouble finding the most up to date information. Recommendations on ROMS / Kernels / combinations?

Okay, I found the kernel ... now I need to find the rom, right? because if I flash the kernel into the stock rom it will freak out ... so it's just a matter of executing two zips from recovery, the rom then the kernel? or am i forgetting something?

As long as the kernel matches the stock rom you can use it. It needs to be a git gingerbread sense kernel of you are on 2.3.3 or 2.3.5 stock if you're on 2.2 stock needs to be a froyo kernel. If you go to something like cm7 or decks reloaded, anything aosp based make sure you use an aosp gingerbread kernel. If you try ics and want a custom kernel or jb make sure to use matching kernels or you'll end up in a bootloop and need to reflash the rom to fix the kernel
Edit: when flashing make sure to do the proper wipes. For a rom wipe everything but the SD card, for a kernel or a modification wipe only cache and dalvik cache. When flashing a rom and a kernel at the same time, wipe everything but SD for rom then wipe.cache and dalvik and flash the kernel

Okay, I ended up installing cyanogenmod 7.2 ... which is a "rom," right? now i see these kernels ... right now looking at tiamat-dev dot com / supersonic ... this would work with the rom right? and what would change by installing this kernel? and which one would i want to download from that list? sorry

Yes cm7.2 is a rom, I always used tiamat 4.1.0 on cm7.2. The kernel will add different governors, clockspeeds for overclocking, change the scheduler and allow for undervolting. The kernel is what allows the rom to talk to the hardware and vice versa, it contains all of the drivers for the hardware.

[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
Sent from my SGH-I747 using xda premium
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!
