Camera and Flash Don’t Work

Neither of my cameras nor my flashlight are working. I repaired my back glass (also made it clear) and in the process I know I accidentally cut of the rear mic. It didn’t seem to damage the flash and power flex but now my flash and camera don’t function. The power button still works though. I also could had messed up the rear or front facing camera in the process as I used dry ice to help get the glass off but I find the flex the more probable cause. Does anyone know if cutting off the mic would cause these issues? If not would damaging that flex cable automatically disable both cameras? Thanks!

Well replacing the flash / mic / power flex did not solve the issue. Neither camera nor flash work still. I am guessing the dry ice damaged one of if not both of the cameras. I would look into the solder points possibly being broken from being contracted by dry ice but everything else on the phone works so I would find it unlikely that just the cameras’ solder points would break. Any suggestions would be greatly appreciated.
