[Sony Cross-Device General] munjeni:
How to install this:

1. put copymodulecrc to the /data/local/tmp folder and chmod them to 755

(adb shell chmod 755 /data/local/tmp/copymodulecrc)

2. put ntfs-3g and ntfsmount to the folder /system/bin and chmod them to 755

(adb shell chmod 755 /system/bin/ntfs-3g)

(adb shell chmod 755 /system/bin/ntfsmount)

3. put sdcardfs.ko to the folder /system/lib/modules and chmod them to 644

(adb shell chmod 644 /system/lib/modules/sdcardfs.ko)

What is next? Next:

1. in order to get it working, sdcardfs.ko must be patched to match your kernel version since every kernel modules is paired with kernel by version string, so if version string not match module version it will not work! So you must patch sdcardfs.ko module using tool called copymodulecrc! Copymodulecrc will extract version string from any module of the your stockrom kernel modules and copy them directly to the sdcardfs.ko (patch them). First of all you need to look into your /system/lib/modules folder and use any .ko file NAME for referencie in next commands:

adb shell /data/local/tmp/copymodulecrc /system/lib/modules/PUT_NAME_OF_THE_KO_YOU_FOUND_IN_STOCK_ROM_KERNEL_MODULES /system/lib/modules/sdcardfs.ko

So replace PUT_NAME_OF_THE_KO_YOU_FOUND_IN_STOCK_ROM_KERNEL_MODULES with the name of the any module you found in modules folder! Done.

2. if you completed step 1 without errors you are ready for this step. You need to locate script called install-recovery.sh (on most devices it is in folder /system/etc) and add next lines:

insmod /system/lib/modules/sdcardfs.ko

Done. On every next reboot sdcardfs kernel module will be automatically included in your kernel.

3. if you get error in patching sdcardfs.ko whole thing will not work! So these step is important! You can verify success by command: (su -c "insmod /system/lib/modules/sdcardfs.ko") , if you see error than sdcardfs is not working, if you see nothing than it is working :)

Since you completed these 3 things, you are ready to use NTFS volumes on your device! To understand these things:

1. first of all, you can not mount ntfs volume regulary trought settings menu since android not support ntfs by default! You must mount/umount your ntfs volume manually (you can use for example android terminal emulator when you need to mount/umount ntfs). You will not see any details about ntfs volume in settings menu since android not support ntfs by default, you can see details in most file managers only.

How to mount and unmount:

1. to mount (first connect your usb ntfs volume to your device usb port) :

su -c "ntfsmount mount"

Done! Your ntfs volume by these command is mounted and you are ready to read/write them using your faworite file manager :)

2. To umount (do in mind - every time before you going to remove ntfs volume from your device you must unmount it!):

su -c "ntfsmount umount"

Done! You are ready to remove ntfs volume from your usb port.

NTFS on sdcard? Yes but you need to modify a bit ntfsnount script! Don't ask me how ypu can modify them, do it byself!

Since somebody complain here about gpl licence, I am not ready ready to share sdcardfs source code with you since it is not gpl licenced, instead it is apache 2.0 licenced by Samsung guys @ 2013 and I no need to share it with you since you wanted to see them forced! I not like when somebody forcing me for something! Find it, patch them, make module of them byself ;)

ntfs-3g is not compiled by me, it is used from here -> http://xdaforums.com/showthread.php?t=1724078

ntfsmount script is created by me.

Copymodulecrc I do not know where I found them but here is source code:
