[Sony Ericsson Xperia Neo, Pro] t3chg33k:
SOS ROM v1.4 (Based on Official Neo ICS 4.0.4)

SOS?

SOS stands for Simply Optimised Stock.

The ROM aims at deriving the maximum out of the stock ROM using various boot-up and runtime tweaks. In short, it is what the stock ROM should always have been.

IMPORTANT:

Note that this ROM has nothing to do with the vendor partition containing quite a bit of bloatware in the official Neo 4.0.4 release posted in the general section. All useful files from the vendor partition have been included in the system partition, so the onus is on you to ensure that the vendor partition is not flashed. For this, refer the instructions below before flashing.

What's changed in v1.4?

Rebuilt from scratch

Experimental 'Under the hood' changes for a better balance between performance and battery life

Included Dialler Lag Fix (Credits: mpiekp)

Included LED Notification Fix (Credits: arcatarc)

*Note: Missed call notifications do not work with this fix by default but Light Flow works fine, so you can customize the LED as per your liking

Included latest version of Volume Button, Power Menu and LockScreen Mod (Credits: 7OH)

*On-screen navigation buttons are enabled by default and can be disabled using the included Full Screen toggle app. Also the included 7 Parts App can be used to customize this mod. Reboot is required for the changes to take effect.

Instructions:

If you have already flashed the official ICS 4.0.4 release, then I recommend that you flash it again by removing the vendor.sin partition from the ftf or selecting the "Exclude uncategorized" option in FlashTool.

Optional: Flash the userdata partition from Neo V (or the 380 to 420MB userdata patch) to get 420MB of space in the data partition

Use an ICS kernel with recovery to mount and copy SOSv1.4.zip in case you have not copied it beforehand. Flash it and reboot the system.
