Two days after I did an update my phone's display flashed twice and went blank. Now I see only 2 lines. I have no idea what to do.

You just described a possible hardware failure that occurred just after a software update.


While this is unfortunate, it is not uncommon.

However, only an Apple Genius can review the cause and provide a complete solution.


Therefore, I recommend service.
