Chosen Solution
I Dropped shattered my phone spectacularly, so much so that the rear housing bent a bit and that the screen shattered. So I purchased a new screen and I was fortunate to have a rear housing from another dead 6S. Everything was working perfectly before the fall, I transplanted the logic board, speaker, battery and power flex from the smashed case, to the straight one with almost no issues, data is there, everything working fine except the flash will not respond at all, whether I use the flash light function or camera. The camera works properly as well. Thinking that taking the flex from the smashed phone (even though it worked in the smashed case) would resolve the issue. But no luck. Please help! I had no idea I depended on the flash this much
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.
