[Q] Issues after installing [4.1.2][XXLSC][Build-3] AmniX"-Xperia

Hi guys i am having two questions regarding the above rom which i have already flashed on my GTN7000 which is international model being used in India:-
a) I was on N7000UBLS4_N7000TCELS1_TCE and then I flashed it using ""Instructions For Stock ICS And unrooted Users:-
Well you Guys Just Do One thing.
Flash This With Odin And Go to Recovery ANd Follow The Instructions As Normal "
I am now getting the yellow triangle so please let me know how to remove that, I have flashed the "PhilZ-cwm6-XXLSC-XJB-3.75.tar" using the PDA option in ODIN ver 1.85.


b) What are DPI settings and Pimp My Rom, Pimp my Rom is in the phone and what about the DPI settings, how to remove them.
