[q] please help (lg su660) topic

Hey guys I upgraded my GB SU660 a year ago using this Tutorial http://forum.xda-developers.com/show....php?t=1889328 and I'm looking forward to flash P990 Custom Roms to it so the Korean feature will be removed. But I have a problem understanding the tutorials here which is too complicated. Can someone please give me helpful links where I can Download P990 Custom Roms, how can I install it and tools should I use. And I will be grateful if you can explain it in detail. Thank you very much, I'm hoping someone can help me. :) :) :)
