Default Cant close it properly

Hi guys im having this problem with my HOX i opened it to try and fix the damn gsm signal lose and not ragaining it.
But now it seems i cant close properly, when i close it the screen lifts just a bit from the left side and i can hear a squeez where the usb port is everywhere the phone closes firmly but where the usb is when i press it i hear a squeez and it closes for a bit but then goes up.
Any one of you had the same problem before?

Im not asking about the gsm signal lose because i m searching everywhere with no luck... only turning airplane mode off and on again i get signal, i have tryed ics,jb,kit kat roms and many radios but no luck.(even try diferent sims, i only loose signal when the phone switches towers when im standing its ok.)
