I am using the XWLSW NeatROM Lite v4.8 dated June 9, 2013 and the firmware version is 4.1.2
Please download the NeatROM Lite v4.8 from XDA Forum here.
Your android phone must be rooted prior to installing the NeatROM.
Pls use the full wipe if u are coming from another ROM or installing your first ROM after rooting your phone.

This is done using the PhilZ Touch 5
Installation without wipe:

-Download, and save zip file to internal sdcard
-Go to recovery
-Select Wipe cache
-Go to Advanced and Select Wipe dalvik cache
-Select Install Rom SD card

Installation with Full wipe:

-Download, and save zip to internal sdcard
-Go to recovery, Select Wipe data, Wipe cache
-Go to Advanced and Select Wipe dalvik cache
-Go to Mounts and storage, select Format system, Yes – Format
-Select Install Zip
-Choose zip from sdcard
-Select the NeatRom V4.8 that you have downloaded
-Click Yes to Install

It takes about less than 3 mins to install the system on a Samsung Galaxy S2, so don’t panic.
You will see a bar running to view the installation progress.
Reboot device after the installation is complete
