so i just want to knw
1. how to unlock bootloader and install custom kernels?
2. which custom kernel is better or best?

1.there are many threads here explaining how to unlock bootloader, so please read a one of them. also as it seems risky for some users think twice.(you might brick your phone) (http://forum.xda-developers.com/showthread.php?t=1436924&highlight=bootloader+unlock)
and when it comes to custom roms, some needs custom kernals and some don't. so decide which rom you want based on their features, looks, etc and if the selected rom needs a custom kernal then you have to flash.
2. read user reviews, also there are some big names like LinuxDX, nAa, alfs etc....
3. nope
4.sorry isn't it showing in "About Phone" section on "Settings"? under "Model Number"?
P.S. i used some custom roms too. but back to stock 2.1 because of battery issues. I used "Sony Ericsson Update Service" aka "SEUS" to reinstall stock rom. and there is a app named "Links to SD" which do the same task of "Apps2SD" so you can free up some memory if you use 2.1.

thanx goldbugbee......

Correction: to goldbugbee
3: yes. For some roms you need a specific Rom. Like minicm uses naa kernel. Etc
Sent from my X8 using XDA App

2.The best kernels out,in my opinion,are nAa's and alf's search them....
3.the best way to flash a new kernel is while being on stock rom
Attention! You wont be able to boot to stock rom if you flash a cutom kernel,so load the rom to the phone before you flash the kernel,anda then through cwm blabla...
4.Pull out the battery of your phone it should say somewhere
I hope i helped you

[Q] Steps needed to flash another stock ICS!!

Hi There ,
I would like to welcome myself to the xda-developers , i have been exploring this forum for a while, honestly i am so impressed, this is the best forum ever
I think i wil learn looots of things from you guys ...i hope i can help out one day as a pay back ...love you..
My question :
1. i have flashed a stock ICS ROM and rooted it successfully ...
now i need to flash another stock ICS ROM..saudi arabia one to get arabic language ...how can i do that short and safe ?!!
Thanks in advance for your help , and please do make it short as i am not that technical :-(

First things first,
there's currently no 'short and safe' way to get stock ICS due to the Hardbrick bug.Read it carefully-when a dev/mod writes warning in big red letters, you pay attention to it.Although you may get a replacement from Samsung as all you did was flash a stock rom and as long as your binary counter is zero i.e. no 'yellow triangle' is displayed when you start up your phone.
For getting the Saudi Arabia ROM-use this

thanks
well..i have installed stock ics rom from a stock GB rom ...now i am confused should i downgrade to GB first or just use pc odin right away to flash this one as well?...
and thanks for the link ...but searching confuses me even more ...so many ways to flash.i need some that have succesfully done the same thing to guide me..

Newer the better !!
ICS is safe with a safe kernel(i.e. a kernel which is devoid of any wipe data bug Eg. All CM9 kernels, speedmod kernel, franco's kernel). If you wanna stay stock in ICS flash any stock firmware through ODIN and replace the stock kernel with a safe one. If you wanna custom ROM, there are many to choose from. Here also the same procedure applies. Any ROM with a safe kernel. so cheerios and Welcome to the ICS bandwagon. You can flash it over the same with a safe kernel also(I have done safe many a time) but it doesn't get hurt to flash into GB and to be back on ICS. A 33k Note is of more value than a time of ten minutes. LOL.
you can also read this thread to get more information on staying safe in ICS.

Yeah mate, no problems. Just restore it from Abyss Kernel 4.2 Redpill if you need too.

There are no problems with making backups in CWM unless you are using an unsafe kernel. Sounds like you are good to go.
CWM, backup, then you're ready for whatever you wanna do next. I have done this many times.

[Q] I am new , please be kind !

Hi ,
I am new to this forum , although i have been reading articles on this forum for months .
I am planning to flash my galaxy note , but have a few questions . (i did some research , but i am still short on some answers )
If anyone would be kind enough to answer my questions i would really appreciate it . (Currently i am on stock android rom + not rooted)
This is what i know : Phone = Hardware + Kernel + Rom .
I also know that we can either change the kernel or the Rom (and that ROM comes with its own kernel which we can change )
Now this is what i dont know and am looking for your help in finding the answers .
1. Can i only flash a new KERNEL on my Note while keeping the stock ROM ? and if YES , then can i at a future time be able to recieve Official smasung OTA updates ?
2. I know the benefits of custom Kernels namely : Performance , Better battery , highly customizable ,etc . But what i dont know are the demerits of custom KERNALS . ??
3. Last Question . If i do go ahead and ROOT and FLASH custom ROM on my phone , can i ever go back to factory settings ??
Please dont beat me , this is my first post . I WILL GET SMART WITH TIME

Well u have a nice question. I am also a newb, but what i know is that if u change ur kernel u wont be able to get the OTA.
Rooted but on stock rom will still offer u the OTA updates.
Well yes at anytime you can return back to stock.

1. Yes you can flash custom kernel on stock rom.. see dr ketan's guide in original Android development section of galaxy note..
You won't receive ota upgrades on a custom kernel.
2.No demerits of custom kernels.. for battery life with perfomamce i suggest speedmod kernel. For higher perfomance i suggest hydracore.
3. Yes you can go back to factory settings by flashing stock Samsung rom through odin.
I strongly suggest that you read dr ketan's guide.
Also remember never do a factory reset or wipe in stock kernel.

what do you mean when you say :: Also remember never do a factory reset or wipe in stock kernel ??
Also i looked up de ketan's guide . But that seems to be about stock rom's .Right ?
Right now i am just looking to install a new Kernal , in hopes that , that itself will provide a boost to the phone's performance and then if i like i will
install a custom rom as well.

Actually stock rom is unsafe for wipes because it may trigger the brick bug
For installing custom kernal u first have to root the note(many methods available)
For that the easiest method i feel is with philz kernal
U can see in dr ketan s rooting guide or philz thread
Then u can move to sppedmod or hydracore or anypther that u like
Plz read all instructions carefully so as to avoid bricking

Basically what you are saying is :
1. Root your phone (using any of the number of ways available)
2.Install custom Kernel as that helps to avoid brick bug when you try to wipe your phone for custom installation .
Also i have another question (yea i know my questions are never ending )
Where and why in all this does a custom recovery come in the picture ?? and why do we need it ? because i have read somewhere that we do .
thanks in advance

if u install a custom kernel like speedmod or hydracore ... it will override the stock recovery option ( vol up+power+home) 3e and install the powerful ClockWorkMod recovery ( same action). this recovery allows you to do a lot of tasks which the stock doesnt

thanks Whiskeyjack4855 , sitanshu91 and nokiamodeln91 . One day in this forum and i am already loving it
I love open source (I actually work in open source as well )
So finally i have decided to go ahead with the root . I will post how it went .
Also which kernel is best after rooting : hydracore or speedmod . Also i have head quite alot of franco kernel .
which would be best and least risky ?

The 3 kernels that you've mentioned are 3 of the best kernel for the note. Franco kernel was cancelled though, the dev decided to leave the note community. Your best bet would be the HydraCore kernel

Try philz kernel.
It is a mod stock kernel, with a mmc cap brick removed.
It is safe mod stock kernel.

i must say u r lucky this time but its been on XDA a million times that using these files can brick your phone. follow dr ketans signature for safest and easiest way to root.
1. if u have used there files to root u still will be on stock ics kernel and cannot do any backups. download philz kernel and flash it from recovery
http://forum.xda-developers.com/showthread.php?t=1901191
after this u will get CWM.. with this you can take a nandroid backup of ur rom and its a safe kernel for wipes as well
2. no flashing kernel will not have any effect on data or apps. but flashing ROMs do

Well Rooted the phone again . This time used philz kernel .
This is what I did
1. Restarted in stock recovery
2.Installed philz zip file from external sd card (it replaced my old SU and installed a custom kernel i guess)
3.Rebooted and working fine .
4 also started recovery again and CWM was installed this time ,
So , sofar everything is fine i guess .
Now should i take a nandroid backup and then install hydracore kernel ?

this is a safe kernel but still if u want to go for hydracore then ya. u can take a nandroid backup now. But b4 that go to backup and restore and set the default backup for may as tar

So i played a bit with my phone yesterday . took a nandroid backup first which came to be around 2.3 gb then flashed hydrokernel 5.4 non OC.
But strangely enough i felt there was a bit of lag in the phone after i flashed the hydracore kernel so i flashed philz lernel again and it worked fine .
today i have backed up my apps using titanium backup and now i am ready to experiment more .
I have 2 questions before i start flashing new ROM's though :
1. Can nandroid backup bring me back to where i am today no matter how big i screw up ?
2. Where do i store the titanium backup , because i assume that if i flash a new rom titanium will be deleted as well .. right ?

No. It depends. it u encounter a emmc brick then it can't it also depends on if u can reboot into recovery.
2. Where do i store the titanium backup , because i assume that if i flash a new rom titanium will be deleted as well .. right ?

external sd. when u take backup. There is a folder created in the internal sd titanium backup. copy that folder to ur pc or ext sd and restore back after installation on new rom and tb.

And i can't turn on my phone =/

What you need to do is to put it to download mode(hold down volume home and power off keys together to enter download mode) then use odin to flash cf root.
