Partial Boot Loop/Won't Start Up
I have an iPhone 6 that was dropped. It shut off after the drop and now when I attempt to turn it on it shows the Apple logo for about 5-10 seconds then shuts off. It doesn't continue attempting a restart like a boot loop typically would. I've attempted a new display, a new battery, disconnecting and a new proximity/front cam flex, disconnecting and a new charge port/headphone jack flex all with no change. I've also tried a soft reset, entering DFU mode, and connecting to iTunes for a hard reset but iTunes does not recognize the device (not that it says it doesn't recognize it but it won't show up as being connected). I don't see any damage to the board either. Anything else I can do?
Is this a good question?
