You are all right ... but you omited a lil important thing... SEUS may upgrade your CID(example i have a k310 and i made my last flash with seus...i had R4EC031 and seus changed it to R3EC001)anyway my phone was CID49 red and after flash with seus it was CID 51 :( ... P.S. procedure reversible... seus only changes the GDFS CID(OTP CID remains the same) so it is possible to get back to old CID...
