How to Fix iPhone 6 Screen Unresponsive and iPhone 6 Not Booting Up

If you’re dealing with an iPhone 6 that either won’t respond to touch or is stuck at the Apple logo screen, you’re not alone. These problems are more common than you think — and depending on the cause, you might be able to fix it yourself before heading to a repair shop.

Here’s a full guide to help you troubleshoot and possibly fix these two frustrating issues.

iPhone 6 Screen is Unresponsive and Showing Vertical Lines

Problem:
Kevin’s iPhone 6 started having touchscreen issues — the screen would freeze, jump around uncontrollably, or become unreadable with violent vertical lines. Hard resets worked for a while, but eventually, the phone became completely unusable.

Solution:

First, understand that this could be either a software glitch or a hardware failure. Here’s how to figure out which one:

Step 1: Restore from an Older Backup

If a recent app or update triggered the problem, restoring from an older backup might fix it.

Connect your iPhone to a computer with iTunes installed.
Select your device once detected.
Click Restore Backup.
Choose an older backup — preferably one from several months ago.
Wait for the restore and sync process to complete.

If the touchscreen still acts up after restoring, move to the next step.

Step 2: Factory Reset the iPhone

If restoring didn’t help, do a clean factory reset to eliminate all possible software causes.

Go to Settings → General → Reset → Erase All Content and Settings.
Enter your passcode if prompted.
Confirm by tapping Erase iPhone.

Important: After resetting, do not restore any apps or settings yet.
Observe the phone for at least 24 hours.

If the screen still glitches even on a clean install, it’s likely a hardware issue.

Step 3: Hardware Repair

If both restore and factory reset fail, your iPhone probably has a hardware defect — most likely with the screen connector or internal IC chips.
At this point, your best option is to take the phone to a professional technician for inspection and repair.

iPhone 6 Won’t Boot Up, Stuck at Apple Logo

Problem:
Laura’s iPhone 6 died while charging at 1% battery. It then got stuck on the Apple logo, kept rebooting, and wouldn’t be detected by her computer.

Solution:

This is usually either a battery problem or a software corruption issue.

Step 1: Let the iPhone Charge for at Least 1 Hour

Use the original Apple charger and cable if possible.
Plug it in and leave it alone for at least 60 minutes.
Do not attempt to turn it on during this time.

If the phone still won’t boot normally after charging, proceed to the next step.

Step 2: Update via DFU Mode

If regular recovery won’t work, you’ll need to attempt a DFU (Device Firmware Update) mode recovery. Here’s how:

Open iTunes on your computer (make sure it’s updated).
Connect the iPhone via USB cable.
Turn off the phone completely (if you can’t, let the battery drain to 0% first).
Press and hold the Power button for 3 seconds.
While holding Power, press and hold the Volume Down button for 10 seconds.
Release the Power button but continue holding the Volume Down button for another 5 seconds.

⚡ If you see the Apple logo or the “Connect to iTunes” screen, you didn’t enter DFU mode correctly — try again. In DFU mode, the screen should stay completely black.

Once iTunes detects a device in recovery mode, follow the prompts to update or restore.

Important: A DFU update tries to reinstall iOS without wiping data. A full DFU restore, however, will erase everything.
If the update option is available, choose Update first to preserve your data.

If DFU mode fails or iTunes doesn’t detect the iPhone at all, the device likely needs professional repair — either a battery replacement or more serious motherboard work.
