k630i 3G problem with the latest firmware..

when i use the last firmware(K630i_R1FA032_CENTRAL-EUROPE) to flash my phone i get disconnected after using my internet connection on 3G..i can only use it for a few time in java applications..i tryed one of the oldest and it worked perfect but it doest look good..now im using K630_R1EA030_CENTRAL_EUROPE..it`s more stable then the last one but i stil get disconnected from time to time..i tryed to update it from this one to the last with SEUS but it doesnt work..it says that i already have the latest version..is there any other way to update my phone to that version without flashing to that version?..
