Hello Team.

Not everyone knows that the NEO was somewhat offended. For some unknown reason to me NEO section /System and /Data partitions are smaller than on other models Xperia 2011.
It is should be fixed!

We will need:
- FlashTool latest versions (version above 8)
- Installed driver in the system (located in the flashtool\drivers)
- Downloaded NEO V (MT11) .587 FW (Find it in the header. Localization does not matter, I Used nordic) (another .587 FWfor NEO V)
- Installed CWM on the phone, or you can find it in the custom kernel (to make a backup of the installed firmware, and restore it after that)

1. Go to the CWM and do a full backup of your ROM. (you can skip, but will have to re-install the ROM again)
2. Run FlashTool and Flash previously downloaded FW from NEO V 587 with this markers:
attachment.php

3. After flashing reboot and go back to CWM. Do factory reset, wipe cache, wipe dalvik cache. And restores the previously made backup.

So what we had:
attachment.php

And what we have now:
attachment.php

As you can see /System increased from 312.5 to 400MB, and /Data from 380 to 420mb.

It's good that you didn't notice any drawback. it means this mod worked for you as you wanted.

Here is the reason I don't want that.
After the mod, /system increased from 312.5MB to 400MB (88MB difference) and /data from 380MB to 420MB (40MB increased).
From where the space from? It is from the partition intended for /system/vendor. After modding - /system/vendor mount point disappeared, means its contents is now in /system partition.

As I do not use stock rom, the 133MB partition intended for /system/vendor can be wasted. But thanks to alliance kernel, it is (automatically) mounted and used for dalvik cache (described HERE). Without it all the dalvik cache would occupy a lot of space in /data.

In MY CASE, the dalvik cache directory is as big as 98MB. By a simple calculation, I just think the mod can increase the data partition in 40MB, but will cause 98MB of dalvik cache to be moved to /data. So I decided that this new partitioning schema is not for me. I need more space in /data rather than /system.

For Locked bootloader the tutorial is much more long.
After flashing neo V system we need to flash .062 neo v kernel, make root, flash .587 neo kernel, install cwm, restore backup of the rom.

You can шадфыр ROM without kernel, and load CWM via fastboot command:
fastboot boot kernel_with_cwm.img and restore ROM

Confirmed.
It works. But flashing new firmware of Neo via Flashtool removes the partition and takes it back to old size.
So the solutions are:
1. Don't flash firmwares via Flashtool (flashing other ROMs via CWM doesn't crash the partition)
2. When you use flashtool,- just flash ROM from Neo V, and than any custom ROM via CWM.

    @MaxWorks sorry for nagging. I get it do i need to flash haida or hallon roms afterwards? And camera is 8mp or 5 mp? What does it says in device info permanently,mt 15 or mt 11? TnX

    NEO (MT15 Hallon) and NEO V (MT11 Haida) have 2 differences:
    NEO V have SYSTEM partition 400 Mb and 5MP camera
    NEO have SYSTEM partition 312.5 Mb and 8MP camera
    Camera drivers stored in /system/lib folder and can be changed by you, or changed by system that you install.

    So, If you flash FTF from NEOV on your NEO phone:
    You will have SYSTEM partition 400 Mb and NEO V Camera drivers.

    You can change it by your own if you want to use stock ROM, or just install NEO ROM via CWM.

    Drivers that need to change in NEO V ROM to make camera works for NEO:
    /system/lib/libcald_hal.so
    /system/lib/libcamera_clientsemc.so
    /system/lib/libcameralight.so
    /system/lib/liboemcamera.so
