It would appear that this version of NEAT Lite ROM for Gingerbread is a one off, custom ROM, by salesale, the developer of NEAT ROM, and is based on Pakistani firmware, (possibly OJP), and has a limited language pack for that region. Possibly, just, Arabic, English, French, Farsi and Urdu?. Also the modem included may not prove suitable for the majority of locations.
This unfortunately is not made clear by the OP's initial post I'm afraid.
Well i tried a straight flash & it didn't work, got stuck on the samsung boot logo. I thought i'd bricked my phone too at 1st or wiped my sd card because when i got into recovery (which was a task) it wouldn't see my card, my phone is all good now though & back to normal... but i'd still like to try a GB rom, its just as a nuwbie i'm unclear of exactly why it didn't work & what i need to do & why.
What i did was factory reset, clear catch, load rom......but no go.
