that's exactly what i was thinking
i already have a titan upgraded to a 3.3x.xx radio and 3.x rom and managed to get this broken titan so thought ill use the broken one as my test phone for flashing and testing software etc.
looking at the usb port, i think one of the pins has become misaligned.. one of the guys in telecom (the new zealand carrier) said the whole pcb has to be replaced..
i was like wtf? surely the pin can be just re aligned? he seemed to think not.. but then again his knowledge of a titan is probably the same as the shop brochure..
the whole pcb replacement thing to me sounds stupid.. seeing as the usb part is right at the end of board.. the rest of the phone works perfectly.
ive emailed olipro via xda so hoping he can offer a suggestion to unlock via sd card
