What should you do if your iPhone 7 or iPhone7 Plus has a black screen? We will show you how to fix it on software. We have shared how to fix iPhone on hardware once (check here: https://blog.cinoparts.com/how-to-fix-iphone-7-no-display-or-black-screen-on-logic-board/), however, sometimes the issue is caused by software issue instead of hardware faulty. Here we will show you how to fix it in terms of software.

Basically, we can divide software solution into two aspects: DFU mode and No-DFU mode. Begin with the No-DFU mode, since it is easier to operator.

  2. If step 1 does not work, try plugging in the power supply and pressing these two keys at the same time. By doing so, we can detect whether the battery is automatically shut down due to the sudden exhaustion of the battery.
  3. If both the steps fail, it is turn to enter the iPhone’s Recovery mode. In short, connect the iPhone to a computer and press the HOME+POWER button for about 10 seconds. The recovery options will appear. Then press OK to reset the phone.

Provided that the No-DFU Mode software fix sometimes cannot solve the black screen issue, then we move to DFU Mode fix.
