Nandroid restores Kernel? - AT&T Samsung Galaxy S II SGH-I777

Does a restore through recovery restore the Kernel or just the ROM and Modem?
I know they used to not restore the kernel but some have been saying that it does restore the kernel now.

Yes. The kernel will be restored along with everything else.
And doing so will not trip the flash counter.

Nandroid in CWM 5.x (the I777 has never had anything older) does restore kernel.
2.5.x (common on first-gen GalaxyS, especially the Voodoo-modified one) did not.

Nandroid Restore Question

Am I able to nandroid restore from MIUI to something with voodoo and vice versa?
I believe you have to odin back to stock first.
the restores are done from CWM so i think yes?
nandroid doesnt back-up the kernel i dont think so you need to flash a kernel thats compatible with whatever rom you backed-up or i think it'll bootloop
using nandroid to go between different CM7/MIUI roms will work (for the most part, as CWM will actually backup the kernel for those). However, you can't use nandroid to go between CM7/MIUI and samsung roms.

[Q]Advice for newb regarding phone backup

Hello everyone,
I have SGS2 with latest stock firmware (XWKI4) for my region.
Now, I would like to start playing with it with roms and such (yes, I already have Jig just as safety net), however I would like to creat as close as possible original configuration.
Now, I have rooted the phone with zergRush by Doomlord sucessfully and made efs backup as well as kernel image backup via HC-kTool. (This is kernel image backup right?) This way I presume I got pretty much untouched kernel image except rooting, right?
What now I would like to do is to make ROM backup and install some recovery. I know that Clockwork that comes with Rom Manager isnt exactly the same as Chainfires CW that comes with CF-Root and I know that Chainfires CW is optimized for Samsung phones (not to mention that they are not compatible with each other).
I guess my question would be is above that I did make sense, and shall I install CW from ROM Backup or get some CF-Root kernel with CW? I mean what do I lose with each solution, or any other advice how to complete ROM backup so that I can recover it if something, God forbid(knock on the wood), gets fishy?
Cheers

If you take some time and search different threads in xda developers forum, you will find many user posting statements not to use ROM manager.
As I do not use ROM manager at all, I did not read the whole posts. That's why I do not exactly know, what the issues are about ROM manager.
(Incompatibility with many ROMs and kernels, but there must be more issues.)
I am using CWM Manager app (included in Chainfire's CF-Root kernel) or CWM5 recovery mode to create a complete system / nandroid backup.
So, in case of an emergency I only have to flash a kernel containing CWM5 recovery and restore my last system backup.
Just to be on the "safe" side, I also copied my efs folder to my external sd card.
And all my apps (+ app data) are under Titanium Backup control.
So, I recommend to use plain CWM recovery backup.
If you are not sure about ROM manager, please search the forums and make up your own mind.
Good luck !
So basically, I can instead of Rom Manager install DarkyROM2 Tool, flash some kernel with CWM support e.g. Hellcat, CF-Root, and boot to recovery and make backup of current rom(with higher compatibility), right?
Sorry if this is obvious, but I have just started with this kind of tweaks...

cannot make nandroid backup

Hi guys! After flashing siyah kernel 2.6.13 i cant finish a nandroid backup with the customized cwm. Does anyone have the same thing? Any ideas how to solve it?
When I run into troubles like this I've just put a kernel on that I knew did work, made the backup, and made sure that I had the desired kernel to flash back to after a restore, so basically I've substituted to get around this sort of thing.
It seems, though, that the kernels are getting more and more temperamental about which ones will flash each other by CWM recently. Siyah isnt as friendly anymore for whatever teason. Because of this I've been using mobile Odin and pulling the tar files out of CWM zips as this works regardless.
Enough space on the sdcard?

Restoring CWM backup

I have never been able to restore backups made with CWM.
Every-time it says something about boot.img not found.
It doesnt mather if I go from stock to aosp, from cm9 to cm10, from stock to cm10.
On internet Ive found that the cause is because of incompatipable CWM versions but an backup made with Siyah kernel can not be restored by Siyah kernel.
I find it hard to believe I am the only one with this problem.
Thanks in advanced!
Well, only different Cwm versions cross my mind as I have been able to restore backups several times. But every time before restoring, as a matter of precaution I flashed the kernel that backup was made with (e.g. Siyah 3.3.1.).

[Q] Help fixing CWM

Some background info: I got my phone used, so the rooting and stuff was done for me.
When I got the phone, the top of the recovery said Semaphore CWM 6.something, I don't know what I did to it but now the recovery says CWM based recovery. I also notice that fix permissions is not there anymore, there is probably more things missing that I never noticed. My question is, How do I get back to the original Clockworkmod?
Also, does anyone want to give me the basics on flashing stuff? I see people talking about Titanium Backup and ROM Manager. Every time I want to make a backup I just go into the recovery and make a backup there. What's ROM Manager? What's the best way to do this kind of stuff?
EDIT: I just booted back into recovery since a while (when I flashed my current rom) and noticed that it's back to normal. It says Semaphore CWM Recovery 6.0.3.8, when it used to say CWM-based recovery 6.0.3.6. Back then, it also gave me a warning called Warning: no file_contexts. That's gone now, should I have anything to worry about?

Usually your ROM comes pre-packaged with a version of recovery.
ROMs that use the Semaphore kernel also generally come pre-packaged with a modified version of Clockworkmod recovery designed to compliment the kernel.
for reference:
if your recovery says: CWM recovery X.X.X.X then its usually the official version
Semaphore CWM Recovery 6.0.3.8 is a modified version for use with Semaphore kernel
CWM-based recovery 6.0.3.6 - is a modified version likely for use with another kernel (They dont always specify)
I would recommend just sticking with whatever version comes with your ROM.
there is rarely a need to change it.
ROM manager is an App that makes flashing clockworkmod recovery easy as well as downloading and flashing ROMs.
but for the most part if you know how to use recovery already your probably better off doing stuff manually in my opinion.
Titanium backup - is an app that lets you back up and restore all of your installed apps and data.
so for instance if you wanted to install a new ROM. you could back your apps and data up with Titanium backup and then install your new ROM and even wipe user data and still be able to get all of your apps back just as they were before you switched ROMs.
in comparison a nandroid backup (the backup done through recovery) backs up everything including your current ROM so restoring from that would also restore whatever ROM you were using when you made the backup.
as an example if you do both a Nandroid and Titanium backup while running android 2.3
then you decide to update to android 4.1
after the update if you restore from the nandroid backup you will be back at android 2.3 with all of your apps and everything back the way it was.
if you restore from a titanium backup you'll still be on android 4.1 but you'll have all your apps back as they were before.
