Both iPhone 6 cameras and flash are not working

I recently bought an iPhone 6. The phone works good overall but has one issue. Both of the cameras are out. I have replaced both cameras twice and still no result. The flash is also out too. I replaced that flex cable with no result. I am convinced this is some sort of board issue. But I cannot determine it. I’m pretty sure there is a short somewhere but I don’t know where. I hate when parts of the board fail because they almost always require soldering. Please help. I have some experience in soldering and this was a cheap phone so it’s no big deal.

Both cameras are powered by the same voltage rail; this is provided by U2301. there are some other voltage rails at play also but if they were bad, most of your phone wouldn't work either. The Flash however is on a totally different circuit (U1602) but it does communicate with the RCAM so it's possible that a "dead" RCAM causes the flash to shutdown.

Were all three defective when you opened it up the first time? If so, did you noticed if the water indicators were red? Also, was this phone repaired or dropped shortly before this occurred?

For the two cameras, you clearly have a logic board issue IMO. As for the flash, it could be a damaged flex so you will want to inspect that for tears or damage. If the flex is fine, then it's being shut down due to the dead RCAM.

None of this is suitable for a DIY repair, you should have it looked at by an experienced micro-solderer.
