Hi all. I'm repairing one 3310 with network problems, I have reflowed pcb (P.A.-Antena Switch zone and HAGAR zone), after this, phone turns on but when shows operator logo on screen, phone turns off

I have updated faid and reset full fact but no solution

could be possible that I have damaged any ic or component?

(sorry for my english)

thnx and best regards
