Team FAH-Q Presents....

Hey guys the following tutorial is for any thinkerers of Stock Samsung Kernel for Samsung Note 8(n5110/n5100)

*Most kernels work the same way but my guide is using this source :D

Step One:

Download the samsung kernel source for your device

- www.opensource.samsung.com

- search for your device(in this case I'm using n5110)

- now download source(in this case MI1 source)

- download Beastools as you will need them later.

Step Two:

After source is downloaded you will have a giant zip file

- unzip GT-N5110_SEA_JB_Opensource_Update2.zip

- next you need to unzip the Kernel.tar.gz file(any zip manager should work)

Step Three:

Now you have your source to build your zImage(kernel) so lets get the toolchain! :D

- get Toolchain from android git server , codesourcery and etc ... arm-eabi-4.4.3

Step Four:

Lets edit the Makefile so it uses the toolchain.

- edit Makefile

edit "CROSS_COMPILE" to right toolchain path(You downloaded).

Ex) CROSS_COMPILE=/usr/local/toolchain/arm-eabi-4.4.3/bin/arm-eabi- // check the location of toolchain

Step Five:

To build the kernel follow these steps.

- Open a terminal

- cd to the location of your kernel source

- exceuted the following two commands:

make kona_01_defconfig

make

- give it some time as it can take up to hours to build depending on your build machine.

Step Six:

Once zImage and modules are built get them together with the ramdisk.

- the following are the locations where to find kernel and modules:

kernel/drivers/scsi/scsi_wait_scan.ko

kernel/drivers/net/wireless/bcmdhd/dhd.ko

kernel/arch/arm/boot/zImage

Step Seven:

Lets extract the ramdisk from a stock boot.img or a recovery.img file.

*use the beastools.zip file attached to this post to complete the following.

- unzip my beastools.zip and place boot.img in the same extracted folder.

- open a terminal and cd to the extracted beastools

- run this command to split ramdisk and zImage:

./split_boot boot.img (if using recovery.img just replace boot.img with recovery.img)

*I have included a script by the name of Unpack_kernel.sh that can save you the last step by just running this command:

./Unpack_kernel.sh (this is if you're lazy lol)

Step Eight:

With your ramdisk extracted make whatever changes you want to it(such as making kernel insecure or whatever)

- grab modules and place them in the ramdisk: ramdisk/lib/modules/ (replace old modules or wifi wont work).

- after modules are placed and ramdisk changes are done continue to step nine.

Step Nine:

Place the ramdisk and zImage in the same beastools unzipped folder

- to repack kernel you can use the script I included called pack_kernel.sh by running( ./pack_kernel.sh)

or

- run the commands on your own:

#Ramdisk Repacking

./mkbootfs ramdisk | gzip > ramdisk-new.gz

cd ramdisk

find . | cpio -o -H newc | gzip > ../newramdisk.cpio.gz

cd ../

#Boot.img repacking

./mkbootimg --kernel zImage --ramdisk newramdisk.cpio.gz -o new_boot.img

Step 10:

You will now have your new kernel named new_boot.img

- rename it to boot.img and flash it through heimdall or make it into a flashable for CWM/TWRP.

My Kernel using these steps and making boot.img insecure/enabling init.d access.

DISCLAIMER:

As always I am not held responsible for anything that happens with your device by flashing anything I make/guide you through making youself.

I am not responsible if flashing my file makes girls more attracted to you either. lol

Hope you guys found this tutorial useful, if so please hit the thanks/donate buttons :D

In case some of you notice there's an extra file I didn't use in the beastools, boot_info (this file will be used in another little guide but in short it helps you check the following things:

- page size

- base address

- ramdisk address

- cmdline

for those that didn't notice that was in there, shame on you! lol jk kinda.

Post 2,3 and 4 will be taken by me as i will post other guides such as how to make boot.img insecure and how to properly flash boot.img/recovery.img to our Note 8.0 with heimdall as I've yet to see anyone flash anything with heimdall to this tablet.

** Guides will be leaned toward making your kernel from samsung sources, making a zip file to flash it, how to flash through heimdall, and changes you can make yourself to the ramdisk. I like to keep guides that are about the same aspect of modding in the same thread.
