    I am trying to compile Linux kernel for my Samsung Galaxy 5 with full Netfilter support:
    The phone specifications are:

    Code (Text):
    1.   Model number : GT-I5503
    2.     Firmware version : 2.1-update1
    3.     Baseband version : I5503DDJG5
    4.     Kernel version : 2.6.29-perf root@SE-S605 #5
    5.     Build number : ERE27
    I downloaded **GT-I5500_OpenSource.zip** and **GT-I5503T_OpenSource.zip** from opensource.samsung.com as they contain the required kernel trees for the samsung phone, and did the following steps:

    I modified the .config file for enabling full netfilter support and then for **GT-I5500_OpenSource.zip**

    Code (Text):
    1. root@preetam:~/GT-I5500_OpenSource_Kernel/kernel# ./make_kernel.sh
    3.     root@preetam:~/GT-I5500_OpenSource_Kernel/kernel# ARCH=arm CROSS_COMPILE=~/myandroid/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- make

    Here i chose the toolchain from android source.

    Now i got the required output, i.e.

    Code (Text):
    1.  CHK     include/linux/compile.h
    2.       Kernel: arch/arm/boot/Image is ready
    3.       Kernel: arch/arm/boot/zImage is ready
    4.       Building modules, stage 2.
    5.       MODPOST 30 modules
    6.     root@preetam:~/GT-I5500_OpenSource_Kernel/kernel#
    I copied this zImage in the phones sdcard, and tried to flash the kernel using **SGS Kernel Flasher**. The phone rebooted, but i could still see the old kernel version in the settings... And there is no netfilter(iptables) functionality.

    I followed the same steps with **GT-I5503T_OpenSource.zip**

    Code (Text):
    1. preetam@preetam:~/GT-I5503T_OpenSource_Kernel/kernel$ ./make_kernel.sh
    3.     root@preetam:~/GT-I5503T_OpenSource_Kernel/kernel# find . -type f -name
