Just to confirm, the rear camera has to work in order to allow the flash/flashlight to work. So you have tried the two flexes and you still have the same issue. That would lead me to suspect a logic board issue with the strobe circuit. It is possible that some damage was done to the solder connections when the phone was physically damaged. This will need to be troubleshooted by an experienced micro-solderer.
