[Q] rom n bootloader/kernal confusion

hey i'm coming from using moto milestone n i'm really confused abt something
since there was no custom kernal for milestone
1) when i root my phone do i unlock the bootloader also ?
2) when i install a rom which says it has a kernal so tht means when i flash it the custom kernal flashes as well on its own ?
3) if i install a rom n then i want another kernal, do i flash it the same way ?

1. Bootloader need to be unlocked in order to root and install custom roms.
2. Each rom comes with a kernel but you can flash other kernels on it.
3. Flashing a new rom will wipe your kernel to a stock one which comes with the rom. But you can reflash any kernel on it.
So basically unlock bootloader> root> install clockworkmod> make backup> install rom> flash kernel> install different rom> reflash favorite kernel again.

[Q] When I install custom Rom do I install custom kernel?

When I install a custom Rom which works with custom Kernel do I install the kernel automatically too? Or I need to manual install the kernel?

Normally the kernel is included in the ROM. If not flash it manually

The kernel will be included in the rom you flash. Whether or not its a custom or stock kernel is down to the developers preference. If the kernel included is not to your liking you can flash a different one.

Thank you!

[Q] wich CWM to flash custom Kernel

I'd like to flash a custom kernel on my rooted TF101 with latest ICS stock rom, but i've not installed a custom recovery.
I tougth to use Recovery Installer app to easily flash CWM (3.2.0.1).
The question is: can I flash a custom kernel (like this) with CWM 3.2.0.1 or do I need a more recent version of CWM (like 5.5.04)?
Another question... after flashing custom kernel, do I keep rooot permission?
thank you for your attention

3.2.0.1 cwm should work just fine

SamHD V2.1 Custom ROM and boot.img issue

Hi guys,
I wish to install SamHD V2.1 which is recently been released by Kumar Abhishek, but this time he has not integrated the boot.img in the zip itself but just posted the ramdisk to make updated boot.img from boot.img of stock ROM.
I am not too comfortable in using SP Flash Tool as its driver always give me trouble, now my question is:
I have made my own updated boot.img using Android Kitchen now can I just integrate the boot.img in the SamHDv2.zip and flash my device like we use to do it with the older version of the Custom ROMs, is it safe to flash like this?
Secondly, would I be able to boot my device properly after flashing SamHDv2.zip and Gapps.zip (without flashing boot.img with SP Flash Tool)?
I am asking so if it boot properly can I use MobileUncle to flash updated boot.img?
I think if I integrate updated boot.img in the SamHDv2.zip it should work fine after we used to flash in this fashion earlier also but I got to be damn sure before I go ahead.
Please guys guide me I am a newbie.

[Q] about kernels of moto g [CM12]

i am not overly familiar with many things regarding different kernels and how to work with them, so i was wishing a few questions that i had could be clarified by someone who knows:
1. when a kernel is flashed? i mean except for the times when we flash kernel.zips via recovery, is it flashed whenever we install a custom rom? or is it flashed with bootloaders when we flash firmware?
2. I am using CM12 official nightly and facing camera frizz issues. I came across a post in the official CM12 thread where they said flashing a modified kernel supposedly fixed this problem. Now my question is, after flashing a custom kernel, is there any way to go back to the stock one? by stock i mean either the one i was on right before flashing the custom kernel or stock moto g kernel provided by motorola?
that also begets the question, can kernels be backed up like roms using recovery?

1. The kernel is first flashed when you install a ROM. You are supposed to flash a custom kernel after flashing a ROM otherwise the rom zip will overwrite it. It doesn't matter if you install it in the recovery or the boot loader.
2. To go back to the stock kernel just take it from the zip of the ROM and flash in the bootloader

where can i find the kernel inside the rom zip?
and if i want the stock motorola kernel that comes with factory firmwares
how can i collect that?

A ROM.zip contains the system folder and a boot.img
The kernel is in the boot.img
So if u flash a different kernel and still facing problems then flash the ROM again.

flashing only the boot.img of a rom wont bring back the default kernel?
and is there any way to make a flashable zip of a kernel from that particualr boot.img?cause all the kernels i see (like donkey kang/customized cm12 kernel) there are all distributed in .zip format.....
