Android : How do I prepare a file to flash my phone with

I have a successfully compiled Samsung Source, and added the module I wanted and compiled again without any problems. I got the zImage. I then followed the procedures below to replace the zImage of a stock firmware with mine. But when I transfer the zip file over to my phone, I can not flash it with twrp. Odin does not recognize the file either so the issue seems to be how I am packing the files. Here is what I have done:

    :~/expermental_stock$ umkbootimg boot.img
    unmkbootimg version 1.2 - Mikael Q Kuisma <kuisma@ping.se>
    Kernel size 8262680
    Kernel address 0x8000
    Ramdisk size 1064985
    Ramdisk address 0x2000000
    Secondary size 0
    Secondary address 0xf00000
    Kernel tags address 0x1e00000
    Flash page size 2048
    Board name is ""
    Command line "console=null androidboot.hardware=qcom user_debug=31 msm_rtb.filter=0x37           
    ehci-hcd.park=3"

    *** WARNING ****
    This image is built using NON-standard mkbootimg!
    OFF_KERNEL_ADDR is 0xFE208100
    OFF_RAMDISK_ADDR is 0x00200100
    OFF_SECOND_ADDR is 0xFF100100
    Please modify mkbootimg.c using the above values to build your image.
    ****************

    Extracting kernel to file zImage ...
    Extracting root filesystem to file initramfs.cpio.gz ...
    All done.
    ---------------
    To recompile this image, use:
      mkbootimg --kernel zImage --ramdisk initramfs.cpio.gz --base 0x1dfff00 --cmdline 'console=null androidboot.hardware=qcom user_debug=31 msm_rtb
    .filter=0x37 ehci-hcd.park=3' -o new_boot.img
    ---------------

I replaced the zImage with the new zImage I built myself, and I compiled using the above command. I then used the following command to pack all the components:

    tar -H ustar -c aboot.mbn sbl1.mbn rpm.mbn tz.mbn sdi.mbn NON-HLOS.bin boot.img recovery.img system.img.ext4 cache.img.ext4 modem.bin > N900PVPUCNC5_N900PSPTCNC5_N900PVPUCNC5_HOME.tar

And I issued this one:

    md5sum -t N900PVPUCNC5_N900PSPTCNC5_N900PVPUCNC5_HOME.tar >> N900PVPUCNC5_N900PSPTCNC5_N900PVPUCNC5_HOME.tar

Then I zipped the files this way:

    zip N900PVPUCNC5_N900PSPTCNC5_SPR N900PVPUCNC5_N900PSPTCNC5_N900PVPUCNC5_HOME.tar.md5 SS_DL.dll
