w580i contacts problem

[Reaper_200]

Im having the same problem on my w550i now,whenever i receive a call,only number shows like its not stored,after i flashed my main and fs files everything was gone except contact list,and now i dont know how to solve this.

Edit:
I've backed up contact lists now then erased them all from my phone and restored them back.Working fine now,problem solved. :)
