Beginner help with Kernels

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

[Q] Kernel to use with u8800-cm7 ROM?

Hi all
I see genokolar's latest cm7 rom for u8800 can't be used with franco's kernel. I use this combo now, on the v11118 rom. No doubt this'll get sorted soon, but...
If I want to update to 111128 now, or if this incompatible issue happens again, what can I do?
Does the geno cm7 rom include a "default" kernel?
If not, what other kernel options are there? Seems to be very few in the u8800 dev forums, and nothing seems to be actively maintained (note, not u8800pro!). Should I return to the stock kernel? And if so, how?
Thanks to all for the great work going on here, my u8800 would have been swapped for something else if it hadn't been for the awesome dev work being done.

every rom has its kernel...

thanks mate

After rooting your phone

Hello,
I have few questions to ask here in the community regarding rom and kernels.
1. Which Rom do you guys recommend that works without any problems (beside cyanogenmod)?
2. If Cyanogenmod which one do you recommend stable or nightly?
3. Which Kernel should i use after rooting my phone that works correctly and has no problems?
Please share with me some of your thoughts and opinions.

1. If you want a 100% working rom with a lot of support go with classic and mikg
2. I don't use cyanogenmod
3.you could stick with stock or try out one of the lionfish kernels. I recommend you use stock voltage one for now

Mikg make sure you download full wipe version http://themikmik.com/showthread.php?10338-MikG-v3-11-3-9-2012
classic http://forum.xda-developers.com/showthread.php?t=1312414

Any other roms do you recommend? Beside this two, which are stable and works with wifi hotspot.

never tried classic, but mikeG is 100% great rom, i need to try out new kernals myself

Myn's Warm series have always been very smooth and stable for me. I'm not going to give you a link, you can find it yourself in the Dev section.

Energy 2/6/12 rom is awesome... nice and smooth pretty much bug free. can be a bit hefty on the internal storage, but with dt a2sd and dalvik on sd card its not bad.

I second this. Wife wanted an iPhone, I wasn't having that. She got an Evo and complained since day one....until this build of MIUI. She is overjoyed now. I've flashed a lot of stuff on mine and am very happy with the look and feel. Much better than any Sense based ROM I have tried by far and doesn't look like any other Android build without heavy customization. Just runs nicely out out of the box.
Doesn't have 4g but I never turned it on anyway.

[Q] Motorola Defy Kernels

hi guys, I would like to ask experienced users what is the difference between the kernels we used on our Defy(s)
Froyo Kernel vs Gingerbread kernel vs Walter79's Kernel
I first encountered this kernel upon viewing the CM9 update thread
I have a red lense defy and the very first rom I flashed was the official CM7.1 so I am aware I do have a Froyo Kernel running on this bad boy.
what is the difference/ advantages?
which is better?
is it safe to flash one over the other?
is it easy to flash? like how we flash roms? we can always go back to to Froyo kernel from the gingerbread or walter kernel and vice versa?
I think a lot of noobs would appreciate your answers.
I will edit this post and add your answers so that others may find it useful as well
some answers--------------------------------------------

Ans:My experience says that the main advantage of using GB kernel is battery life..
Defy-4.5.3-109_DPP-11-kernel is well known for awesome battery life.
which is better?
Ans: I personally think Walter79's kernel is better in every sense.Unfortunately for old defy owners(SOC camera green lens), camera wont work on new kernels without any extra fix..
is it safe to flash one over the other?
Ans: Yea its 100% safe..i personally never had any problem as such..but i heard few people faced bootloop..in any case you can always go back to froyo or watever kernel u were using
is it easy to flash? like how we flash roms? we can always go back to to Froyo kernel from the gingerbread or walter kernel and vice versa?
Ans: As i have already mentioned above, we can always switch between these kernels..just remember not to flash any GB kernel based sbf or else u will be stuck! before flashing any unknown or less known kernel PLEASE USE THE SEARCH option and know more about the kernel and related problems.
All the best

It's easy and safe to switch between kernels, you should only remember that switching kernel must come with installing appropriate rom

thanks for the answer, somehow it has enlightened me
any more answers? which kernels allow 720p recording?

Thanks for this information bro!!
Please also share Camera fix (link) for GB kernel for SOC Camera and also mentioned whether downgrade is possible. Your help will be appreciated.

anyone correct me but we can do dual boot but can't install dual kernels?
say
cm7 (froyo kernel ) as system
cm9 (gingerbread kernel) on SD
and will Gingerbread kernel work with cm7 for the defy, red lense?

No, can't do it. Both ROM's should share the same kernel.

thanks Auris, would you be able to add anything or negate anything that was previously posted about the Defy Kernels?

Please help me a bit with those kernels! I have a defy+ with 2.3.6 base and one of those newest official build nandroids. Can I flash Walter's kernel? ^^
Just don't want any bootloader error!

Is it okay to flash defy+ rom zip and then the gb kernel on a green lens defy? To me battery life is more important than camera

Walter79's kernel allows 720p recording for defy red lens.

Defy kernel Flash
i have a motorola defy green lens currently running cm9 4.0.4 (camera's not working but i don't care much for the camera ) . ok here's my problem i'm trying to flash a different kernel on my defy.. the current kernel im running is 2.6.32.9 cdt 2011 but i need better performance and i tried to flash semaphore kernel. the flash was successful but i see no changes and also in the settings>about phone the kernel version hasnt changed. i need help so that i can flash new kernel properly.. thanks

Hi!
I realize this is a very old thread, but it seems to be one of the few addressing the (dis)advantages of the froyo vs the GB kernel (independently of the ROM!).
The 720p-recording is really not important to me, but battery life is and I just read here that it would be better on GB kernel.
Do any of you have further experience with regards to battery-life difference between Froyo and GB kernels (not ROMs)!? Is it a big difference (to what extent or through which features?)
I have a MB525 with red lens and Froyo kernel, so I could go for a GB-kernel.
I've recently rooted my smartphone and flashed WIUI (3.1.27, GB&MIUI-based) on it, because (1) my phone was slowing down, (2) I wanted not to have any bloatware anymore and (3) I wanted some apps that only run on Gingerbread/2.3+ (e.g. the offline-language-package-feature from Google Translate). Almost everything is now better.
BUT, my battery life got worse! I've now down-volted my smartphone to a stable point and set it to 'smartassv2', but am looking for further improvement for the battery life. As WIUI can be installed both on froyo and GB-kernel, I might also update the Kernel...but only want to take the plunge if it really would make a difference...
any advice or experience is welcome!

[Q] [HELP] Downgrading to froyo kernel WIUI

I've really searched everywhere but it's too complicated and i can't seem to find a solution.
So, my issue is that i have installed the ICS CM9 with GB kernel, but i want to install the WIUI 2.4.20 Stable (GB) version that is based on MiuiAndroid 2.3.7 (GB).
I am assuming it requires the Froyo kernel, and if so, i need to somehow downgrade it to froyo before installing it, but i don't know hot to do it...
can anyone please help me?

Also the kernel version of my rom is "2.6.32.9-g21f1a48"

Questions go in the Q&A section

as far as i remember 32 is froyos kernel..(35 is gb's kernel)
so what is the problem???

Numbers are the same I thought. If you flashedthe gingerbread kernel from the recovery, just search for the froyo kernel zip (there is one on epsy's site) and flash it with the froyo based ROM.
Don't forget to wipe.
