A few months ago, Apple launched a new self-service repair program for its devices, starting with select Apple iPhone models, and plans to expand the list of devices in the coming months.
Currently, the self-service repair program provides the repair manuals, parts, and tools needed to repair the screen, battery, bottom speaker, camera, screen, SIM tray, and TapticEngine.
When using the self-service repair program, in most cases you will need to put your Apple iPhone into diagnostic mode. In this step-by-step guide, we’ll show you how to quickly and easily put Apple’s iPhone into diagnostic mode.
How to Put Apple iPhone in Diagnostics Mode
Step 1: On the Apple iPhone, press and hold either volume button and the power button and wait for the power off screen to appear.
2nd step: Drag the slider on the screen to turn off the smartphone.
Step 3: After that press and hold Volume Up and Volume Down buttons on your phone.
Step 4: While pressing the volume buttons, plug the Lightning cable into the iPhone and connect the cable to the power adapter or a computer.
Step 5: After connecting the Lightning cable, wait for the Apple logo to appear on the screen, then release the buttons.
Step 6: When a message pops up saying “Diagnostics helps Apple identify potential hardware and software issues with this device”, tap on the “Start Diagnostics” option.
That’s it. Once you have followed the step-by-step process mentioned above, your Apple iPhone has now successfully entered diagnostic mode after being restarted. You can now continue with the Self Repair Service program on your smartphone.
