With the current litening 1.5 ROM which features of the "tweaked" kernel would I lose if I flash the stock kernel to get rid of the yellow warning? (The stock kernel differs from the 1.5 one, according to the md5 checksum check as well) Feel free to answer in full tech detail, I have extensive understanding of the linux kernel.
Thanks in advance.
I tried to reply in a similar question directly in the litening forum but I am not allowed to post there for whatever reason ...

I've always used which ever Kernel come shipped with the ROM, until FroydVillain 1.5.0 gave the option to download the kernel separately.
I have since learnt that you can pretty much choose any kernel with any ROM as long at its compatible.
What are the rules for this?
How do you know which kernel you can use with which ROM?
Hi All,
I searched the forums and though this question has been asked couple of times, I failed to get a satisfying and consolidated answer, so seeking a solution here.
Scenario: X10i, 2.3.3 Stock, rooted using aZuZu. Self-customized framework-res.apk and SemcUxpRes.apk and a truckload of apps. Poor battery life, slightly laggy.
I am equally drawn towards CM7 as well as Wolfbreak 4. I know that both are completely different flavours, but much as I love the Cyanogen innovations, so do i love the tweaks done in WB's ROM with minimal changes to the UI.
Questions:
When I backup my current ROM using xrecovery, what all elements get backed up? More precisely, if I make a backup of my stock ROM using xRecovery, will it backup all the installed apps, conntacts, messages and appdata?
If I restore this backup at a later date, will I be able to get back my phone in the same state as it was backed up? (e.g. I am on level 14 on angrybirds and I made a backup, wiped my phone, and then restored the backup, will I have to start Angrybirds afresh or I can continue from where I left off, as though nothing had happened?)
Is it possible to have multiboot on the X10? So that Everytime I boot up, I can choose whether I want to load the CM7 ROM or the WB4 ROM?
Thanks in advance.
1 yes, the things you mentioned will be backed up (but not the baseband & the kernel)
2 yes, you can play angry birds from where you left off (but as I said you can't backup/restore baseband & kernel)
3 no, not yet. Before official gb there was a solution for dual booting a 2.1 rom with a 2.2/2.3 rom, but I believe dual booting two 2.3 roms is not possible for now

Thanks for that! Just a couple of doubts here:
As you mentioned, the BB and kernel wont be backed up. How exactly will that affect my device? Will it lead to any compatibility issues if I restore to a backed up ROM?
Do I need to keep a note of the Baseband and Kernel versions of all the ROMS which I intend to flash, and flash the corresponding bb & kernel versions prior to recovering a backed-up ROM? To be more clear, supposing I am on bb .71 and kernel 2.6.29, and I flash a new ROM with a different kernel. If I wish to go back to stock by recovering my backup, will I have to flash the bb .71 and 2.6.29 kernel again?
I noticed Woflbreak's ROM uses kernel version 2.3, but I am on a different kernel version (2.6.29). Do I need to downgrade to 2.3 kernel before using the WB ROM? Won't an older version of the kernel cause a drop in performance?
well to sum it up yes you need to keep a note of kernel & baseband for avoiding any compability issue, the kernel part is pretty easy, 2.1 roms all use the same kernel & 2.3 roms another kernel, If you want to go from a 2.1 rom to a 2.3 rom you need to flash the appropriate kernel (& the baseband) with flashtools, but switching from a 2.1 rom to another 2.1 rom or from a 2.3 rom to a 2.3 rom shouldn't be a problem kernel-wise, you just need to pay attention to the required baseband & flash the right one if necessary
what rom are you on?
& by the way 2.3 on Wolfbreak is not the kernel, it's the android version
the bb and kernel are in a 7zip archive linked on the page for wolfs 4.0 along with the newest patch. it explains how to do it all on the page. You must take into consideration when trying a new rom the basebands that it is made for.
Basebands can be found here.
Most newer roms will tell you in the post which baseband you need.
Also see if users post other working baseband versions along with kernel versions. how to use a custom kernel with it and a post explaining custom kernels is here.
Hi all,
Sorry if this is kind of double post ( I have been advised to post it in this section)
Firstly I am a complete newbie so any step by step guide , pointer to the correct link or direction is so much appreciated.
My situation is:
I have SGS2 with:
Model Number: GT-I9100
Android Version : 2.3.3
Baseband Version: I9100xxKG1
Kernel 2.6..35.7-I9100ZSKG2-CL361136
Build number : GingerBread ZSKG2
1. I want to try either Litening Rom 6.1 or Darky ROM.
* Is this the correct Link to follow?
Darky: http://forum.xda-developers.com/show....php?t=1159920
Litening : http://forum.xda-developers.com/show....php?t=1095274
** Do I need to root the phone before installing the Litening ROM? or can I go ahead with my current spec and flash it with Litening ROM via ODIN?
2. I want to preserve my Current state of my Device before flashing with Darky or Litening.
* Is it possible to back up everything so I can return it to the way it is for Warranty purposes?
* or is it not possible to put back when we installed Darky or Litening?
3. Which one do you recommend Darky or Litening? - which one is less bug at this stage?
I am hoping that by flashing with the custom rom, it will make the device
- faster more efficient
- still able to get good GPS signal (or better)
- Good Wifi reception (or better)
- Good battery life (or better than now)
Please let me know if this is a false hope?
Thanks guys - sorry for the very basic questions.
Regards,
I am wondering if anyone else has experience the same process and would like to share their tips .
Thanks again guys

First its your own choose for a ROM.
But if you will Litening rom you must flash it with Odin.
For Darky ROM: I dont know.
For a better battery life check this thread.
Speedmod is the best battery kernel.
Your device is not very faster but a little bit.
I dont know about wifi and gps.
P.S I dont have a rooted SGS2
I found this link here:
http://forum.xda-developers.com/showthread.php?t=1095274
is this the one I need to follow?
Do I need to install speedmod or CWM separately if I want to install Litening ROM?
can I directly flash directly from :
Model Number: GT-I9100
Android Version : 2.3.3
Baseband Version: I9100xxKG1
Kernel 2.6..35.7-I9100ZSKG2-CL361136
Build number : GingerBread ZSKG2
to Litening ROM 6.1??
Thanks again
Yes, you can.
Litening rom will be a bit faster than Darky rom because litening will have already a overclocked frequency to 1.6Ghz with it.
Every custom rom build using stock like Darky & Litening & Villian will provide more stable system than Cyanogen, MIUI & AOSP roms. That's what I've experienced.
Problems that you may faced after flashing custom are it may has bootloop, stuck on splash screen. If you got a bootloop, try flash it again, sometimes it needs to flash twice. If splash screen never pass then do a full wipe in CMW, wipe user data, partition, wipe delvik.
Hello
I'm new to this...
I was wondering if I can install the SpeedMod Kernel on my SGS2??
Why this Question:
When I rooted my decive with cf-root and odin I have chosen the Kernel with the same "version" my stock kernel had.
Now I'm not sure if I can install any sgs2 kernel (in this case SpeedMod) or if the "version" is important.
I think that all SGS2 Phones should have the same hardware so I sould be able to use any Kernel. Is that right?
What do I have to be aware of, when I choose a new kernel?
Thanks
Ditschi
Yes you can, don't worry about it. Versions don't care much after all.
Thanks a lot thought that. I'll flash he kernel tomorow.
But what im interested in:
When you say the version doesn't matter why are there so many versions of cf-root? Is'nt that a lot of extra work? Why not useing only one kernel?
Cheers
Ditschi
That's for people who want to stay as close as possible to stock.
The developers compile their kernel to work with any Samsung or TouchWiz based rom.
CF Root extracts the kernels from the specific rom, adds in the goodies and presents it to us for use to root the respective rom. So basically what you have is the stock kernel with root added among other things
ah ok...
That makes sense. Thanks a Lot for the help
Hi, where can i find stock kernel for vibrant froyo (2.2), all the links seems to be broken
thanks
These aren't for just the stock kernel, but check this thread out:
http://forum.xda-developers.com/showthread.php?t=1036193
It particular this post (#224) by Fishman:
http://forum.xda-developers.com/showpost.php?p=24149078&postcount=224
That's an entire stock ROM (also rooted and busy boxed) with the stock kernel included.
For Froyo or GB Roms Id say try this:
http://forum.xda-developers.com/showthread.php?t=1627070
The Jaeyoon kernel is basically a stock froyo 2.2 kernel with Voodoo enabled.
I fixed the links in my original post. Copied that from somone that asked for a stock ROM and didn't pay attention that it kept the ... in the middle.
Thanks...
Thanks everyone for your help, i´m downloading some of the images i´ll try to see what fits better to me....
