[q] omgb 1.1.1

Who is running OMGB 1.1.1? I am thinking about switching kernels and wonder what is compatible with that ROM? Also, how risky is it to switch kernels. People keep telling me you can ruin your phone.
Thanks!

Are you currently using the rom and if so, what is wrong with the default kernel?

Rooting can ruin your phone. A bad flash can ruin your phone. The good thing about flashing kernels and I've flash a lot of them, you usually can go back into recovery and flash another one if your device doesn't play well with a particular one.

I am currently running CM7 and. Kernel 2.6.37.4 cm. Looking to switch today

I hear ya. I'm itching to flash it right now, but my wife and one of my sons are enroute to Orlando and I don't want to flash a rom that I'm uncertain of in case I need to contact them or vice-versa. I haven't had a "home phone" in years. We all have smartphones..lol

I went ahead and flashed this rom and then added my 3rd party apps and I must say that i am impressed. It is stable and everything appears to work as it should. I did notice a bug where when you add a pattern lock, the default lock screen no longer displays, not even after a reboot. I just finished making a nandroid backup of it and will definitely use this rom. This is shweeeet!

You can flash an AOSP kernel. The SBC kernels can ruin your phone. I am using tiamat nonsbc aosp kernel with this rom.

Thanks for the info guys! I ended up flashing OMGB rom and like it so far. Do I flash that kernel over the rom then? Do I just find the kernel in one of these threads or is it on ROM Manager?
Thanks

[Q] changing roms

Hello,

Each rom has its own kernel so dont fear you do not have to manually change anything yourself. Just update the rom.
Going from 2.2 to 2.3 I would do a clean wipe and not just cache and davlik. Do a search for Caulkins format all which would be very helpful when going from Froyo to Gingerbread. It will give you a clean slate to start with
Please note Caulkins format all is a zip file that wipes all data on your phone. Then you can install any rom you want and usually has less issues. Also you may have GPS issues when going from 2.2 to 2.3. Try and read up on this stuff prior to flashing so you know what your getting yourself into..

^^^^ He is right. Every ROM has a kernal already. Untill you learn more about switching them I wouldn do it yet, you could break or brick something.

Ok, well if I switch my Rom will the kernel change automatically?

Yes, a new kernel is bundled with the ROM

Correct me if I'm wrong, but at this point I don't even think there are any custom kernels to install on 2.3 until the source code is released (if ever)...

Dont take this the wrong way but if you are unsure if a kernel comes with a rom I suggest you do a lot of reading up before flashing. Custom kernels are just that custom and flashed separately. Also certain kernels are for sense and different ones are for AOSP. Please try and understand that first before just flashing away. Asking questions may or may not be the way to go up in here.
I SUggest reading the stickies and threads done by people like toastch, caulkins xhausx and others similar to them. They have experience and a good track record as far as I am concerned

You are correct. There are, however, kernels with a few tweaks if I remember correctly, fixing Wi-Fi and maybe another issue (4G I think, not sure)

[Q] Noob Question lol

What is a kernal and what does it do? Is it any different than a ROM? And how do you flash/install a kernal. I've flashed a few roms on the past few phones but I still have no idea what a kernal does.....any help appriciated..

You install a kernal simply by wiping caches,(cache and dalvik cache). Custom kernals allow you to do things a stock kernal wouldnt allow. There are some great developers of kernals here on XDA. You really just need to Search the forums for all of your answers, even google it. Once you do learn what a kernal is,you will be able to enjoy the full, or almost full, potential of your phone. Good luck!!

In a nutshell a kernel is the "heart" of the OS. It's really simple to flash. You start by making a nandroid that way if something goes wrong you have a backup, then wipe cache/dalvik 2x each, after that you can flash the kernel. It's a rinse and repeat process.

Quick question. I see that they are labeled like [sense] and [AOSP]. If I'm running MUIU as my rom right now, would I use an AOSP Kernel or does that matter.

Definitely matters. You need an AOSP kernel like Tiamat or Savaged Zen. I had good luck with Tiamat, but I'm running the stock kernel at the moment.

It wouldn't be a good idea to you a Sense kernel on anything besides a Sense ROM, or you will get a boot failure. I believe that MIUI use AOSP kernels.

[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.

[Q] RenovatePLUS rom help! + kernel/etc questions

Hi guys I have just flashed this ROM (http://forum.xda-developers.com/showthread.php?t=1705334) however it is not the renovatePLUS version, how do I flash with the PLUS version, need it since it has mods and tweaks which I will need, auto-inverted rotating screen is driving me nuts!
FYI: I downloaded the plus zip but I dont know what to do with it, do I just extract into my phone? Because that did not work.
Also, I saw this guy, username(csec) with this signature (Phone: Renovated Endeavoru, F4, XM-Kernel #296 (Most fantastic combo in my entire experience with HOX)). I want to use have those thing stated, already have Renovate(will flash PLUS once I know how), and there is F4, anyone knows what that is? and finally XM-Kernel #296, which I believe is this (http://forum.xda-developers.com/showthread.php?t=2136731), can anyone please confirm is that is a similar one that I can use? Sorry for asking so many question, I finally decided to go deeper with flashing kernels and stuff and I require some professional advice, so please help! Thank you!

It doesnt seem to state on that thread that I have to do it through recovery. But thanks anyway!
For kernels I have one more question. Can I just use the kernel as provided? Of course checking that it is meant for my device 1st. Because there seems to be this confusing thing called repacking...

I RUINED my device before with kernels i didn't know how to use them and obviously i bricked my device so please dont try anything unless u gain experience
Repacking is like making peanut and jam sandwich its like making the kernel work with ur rom if u are using renovate u dont need to repack for XM kernels

If there are no Ramdisc tweaks in the ROM, you don't need to repack the kernel... Mostly kernel repacking isn't needed for Sense roms... So you just have to flash the boot.img from the kernel's zip and then flash the modules from recovery...
AOSP/AOKP Roms need kernel repack each and every time before flashing!

Help once more!
Hi, so after researching a little bit more, I decided change my kernel to the XM kernel(original non-repacked), tried it for a few days, noticed that it response quite slowly compared to default kernel, things like slow display of lock screen upon power on, less smooth transition when. Could I have done it wrongly? Other than the slow response everything else seems fine, I noticed one of the features is S2W, I tried that on my buttons and it worked, however fast charge usb and usb mass storage isnt working, is there somewhere I can enable it or do you have an idea where I can find a guide for XM kernels that describes its features and functionality? Sorry for asking so many questions, thank you!

You have rather detailed instruction how to deal with fast charge and USB mass storage in XMister's thread (first one or two posts).
I suggest you install some of the kernel manageent applications:
- trickster MOD
- Set CPU
... There are many. Choose one that fits you (I am personally using Trickster).
There you will be able to play with your governors and scheduler, and thus achieve better performance or battery life. Or both. Check Q&A, there are few very educative threads about it.
You seem to be on a good way. Keep reading.
