Hi everyone!
I installed last nightly build of CM 10.1 (31/03/2013) on my Samsung Galaxy S I9000.
I also use the standard kernel that comes with CM distribution and Semaphore's ClockworkMod Recovery 2.7.4
Everything is working great, my old phone is reborn! Except for the excessive battery drain...
I read that to solve that problem one possibility is to flash a different kernel (such as Semaphore's one or Devil's one) and to change the modem. Anyway answers on the web are neither organic nor clear.
According to you:
- which is the best kernel to use in order to solve the battery drain problem? (please give me the exact version)
- which modem should i install? and where do i find it?
- [noob question] if I flash a different kernel and then i upgrade to a new nightly build do I have to flash the different kernel again? I mean, if I upgrade to a new CM release my kernel is replaced?
Thanks a lot for your precious tips!
currently I'm using this http://forum.xda-developers.com/showthread.php?t=2024269 with the updated 4.2 devil kernel, quite fast, not having much luck with the modem though as the supplied one didn't seem to work, flashed a few from this thread http://forum.xda-developers.com/showthread.php?p=30588173&highlight=nz#post30588173 and finally got signal, but I'm unsure if these were meant to work with cm10.1 or not as it was an older thread for cm7/9 etc.. and I can't seem to find any info on cm10.1 modems specific to NZ
as for your kernel question; it kinda depends on the ROM, if it's an update then you will keep the kernel you had earlier, but new ROMs usually come with their own, I like to try out a few different ones and decide for myself what works for me, just make sure your kernel is made for the android version of your ROM, eg: there are devil kernels for 4.1.2 that will not work on 4.2.2, you need the 4.2 specific, also applies when flashing gapps..
Mackay and Infamous are really great and smooth. The built in kernel is very good. Set deep idle on but there is not much difference between cm10.1 kernel.

Hi everybody,
I'm still on CM6, mostly because i want 720p recording, and i have to say that IR kernel give me about 30% more battery life compared to stock CM6 kernel.
Unfortunately I'm not able to use any of the last IR kernels.
If I try to install any of the 2.6.38 based kernel i get a bootloop, so I'm using the last based on 2.6.37 (31 march). With this kernel my battery life is very good, but I can't connect my N1 via USB... the notification does not appear... I think it's a bug.
The kernel I'd like to use actually is the last one at the time of this writing: 2.6.38.4_AVS-CM6_CFS_20110424_1137.ZIP
But even if it is marked as for CM6, i get a bootloop...
Anyone have the same problem? What is the best/last IR kernel for CM6?
Thank you very much and... sorry for my English

Use 2.6.35 kernels, they're the last for Froyo, if I remember right. Look at the kernel version explanations in iR's thread, you'll see.
I'm using IR Kernel based on 2.6.37 and it's working fine, except for the USB problem.
What I don't understand it's why for each kernel release the developer still upload kernels for CM6 even if we can't use with Froyo...
I mean...
2.6.38.4_AVS-CM6_CFS_20110424_1137.ZIP it's supposed to be for CM6 and
2.6.38.4_AVS-CM7_CFS_20110424_1139.ZIP it's supposed to be for CM7
but the one for CM6 doesn't work with CM6...
Unfortunately I cannot post on development section, otherwise I would have asked him on the right thread http://forum.xda-developers.com/showthread.php?t=653598

Do you have the location please ?
Hi !
I use Semaphore 2.7.4 with JW6 and though it's good, it still lags and the screen freezes at times. I am in Thailand but use Australian firmware cause officially there is no 2.3.6 for SGS here.
Tried midnight and speedmod but they are not so good for my phone. Is there a Devil's kernel available for this Rom ?
Somebody please advise me !
Thanks !

There isn't Devil kernel for JW6, only for CyanogenMod 7 and CyanogenMod 9. I think you tried all of available kernels. You can also try CF-ROOT kernel (only root, without mods in kernel).
JW6 is one of the latest and best ROMs for our I9000, so I'm shocked that you are not happy with it. Lags? Freezes? When?
Maybe you have some bloatware that are slowin' down your phone?
If you want stable and fast ROM, flash stable CM7 and use it's stock kernel.
CM9 is also good, but latest nightlies have some random issues (eg. weird ringer, missing power widgets).
Maybe try MNGB by Mialwe. It's my favourite, because it has many features and is responsive and fast. I never had lags with the kernel and it is made for JW4/5/6!

Happy testing
I am newbie so please forgive me, Can some one please explain to me what a kernel is and why it matter?
Also say for example I install Werewolf CM10.1 ROM does the kernel also change to WerewolfJB automatically?

Yes because CM Roms run on different kernels and cant be used on stock or stock based kernels. And wise versa. And Kernels are...well not sure how to explain it. Let me try it. Is basically like a transmission. So better the transmission is so better runs and shifts the car. That's basically on a phone the same. Yes the processor is important but the kernel is what makes everything run like it should. I installed a costum kernel because the original one was so bad in battery life and this costum kernel is much better optimized. No more 10 or more % battery drain in standby in an hour. Battery life was pretty terrible on this phone now it is like a fully new phone with ok battery life.

The kernel is the core-engine all other software runs on. To make an analogy with a car:
The chassis of the car is the phone, the engine is the kernel and the body is the ROM. This is not a very accurate analogy, but I hope you get the point.
Different kernels focus on different keypoints. Some are very battery-friendly, some favor performance, some offer extra functionality to the system, etc..So there is not a one-size-fits-all perfect kernel.
ROM's are usually based on a certain structure, which the kernel has to support. So for a stock ROM you need a different kernel then for a CM ROM. Most ROM come complete with a kernel, a few don't. So if you flash a ROM which contains it's own kernel you overwrite the kernel that is on your phone. So let's say you've got the Optimus Prime kernel and then install the latest CM build, you overwrite your OP kernel and have to re-flash it after installing the ROM to get it back.In your case the Werewolf CM10.1 ROM comes complete with the Werewolf kernel.
Hope this answers your questions.
I currently have the JB based SweetRom v7 installed on my Galaxy Note.
Recently it was pointed out to me by a friend that CM based ROMs have a better functionality and are easier to use. Me, never having used a CM based ROM (not even on a friend's phone), am kind of in a dilemma whether or not to switch.
It would be of great help if you could help me out with the Pros and Cons of both JB based and CM based ROMs and if I should give CM a try. Also, a list (If possible) about the features which might not work/are absent from CM based ROMs..
Also, an elaborate guide to switching from JB to CM and a ROM suggestion for a first-time CM user will be very helpful.
Thanks in advance guys.

I'll answer part of your question. If you switch to a CM-based ROM, you won't be able to use S Pen-based apps such as the S Note, as it is tightly integrated into Touchwiz.
4.1.2 JB LT4 Union ROM v7, LT3 Modem, PhilZ LT4 kernel, Carrier: AT&T (US)
Will i not be able to use only the apps or the S-Pen as a whole?

You would not be able to use Samsung applications for S-pen but you can use their alternatives from play store, also FM does not work but you can use Spirit FM, No Wi-Fi Direct but you can use the alternatives from play store.
Edit: Just so that you know, CM based roms are much faster and smother than the TW or stock rom. Also has lot more customisation to it compared to TW. TW also has customization but you will have to apply then or use a customized TW rom.

Yep, as already was said here, the spen apps, and functionality like scrolling, hovering stuff doesn't work.
Not every ROM is the same, so ones can be faster and others slower.
If You would like to have many many options I would recommend You to flash the jellybam ROM. It's slower but greater.
You may also try android 4.3
Okay, So I finally decided to go with JB 4.2.2 SuperNexus ROM.
I'm still confused about how to flash it. I've gone through the procedure and I understand it all but I'm now sure how to Switch from Philz recovery to CWM recovery?
I know this sounds stupid but this is the only thing keeping me from flashing the CM Rom.
Do I flash a CM based kernel to change from Philz recovery to CWM or is there something more?
Help will be greatly appreciated!
As for note the recovery is in the kernel, you will need to flash a cm kernel.
But you could directly flash it using philz recovery. When the rom installs it will install cm kernel and overwrite philz kernel.

So I just need to flash the ROM and Gapps through Philz recovery to get it working?
All that head-banging went in vain, I guess -_-
Thanks a ton!
it wont go in vain.. will come handy some day,. there was an issue with Philz recovery not able to install CM/AOSP roms.. (error 7). which was resolved in the latter updates,, if you get the same error ... then flash a CM kernel first and then reboot recovery and flash the rom.
Hi,
I was just checking if there is a latest version of devil kernel or just let me know which one was the last release with a download link if possible.
However, i am really new with such stuff . I am currently using CM 11 based AVATAR rom with CWM 6 recovery . my Phone has been really sloppy these days and came to know that Devil kernel will overclock the the processor and will have more ram . currently i am using "speedmod kernel "

Will appreciate if you share a link for walk through .
Thanks

Actually, you are using the CM kernel. Speedmod gets overwritten when flashing CM (also, speedmod only runs on 2.2 based ROM).
Now that being said, Devil kernel does allow you to overclock (OC) but it is not recommended. If you phone feels sloppy, chances are that it's cause of something else (too many apps/widgets, low internal memory, etc.).
