🔄 What Is a Boot Loop?
A boot loop is when your iPhone gets stuck in a restart cycle — it shows the Apple logo, seems like it's starting up, then restarts and shows the logo again. This can repeat endlessly.
Common causes:
- Failed iOS update: Interrupted or corrupted update
- Jailbreak gone wrong: Unstable tweaks or bad jailbreak
- Storage completely full: No space for iOS to function
- Battery issues: Dying battery causing power drops
- Corrupted system files: Software corruption
- Hardware failure: Logic board or memory issues

📋 Difficulty & Time
🔧 Diagnose & Fix Won't-Turn-On: Step by Step
Step 1: Charge for 30+ Minutes
If the battery is fully dead, the device shows nothing on screen even when plugged in for the first few minutes. Connect to a known-good charger and wait 30 minutes minimum before assuming it's broken.
Step 2: Force Restart (the most common fix)
Force restart bypasses any frozen software state:
- iPhone 8 and later: Press Vol Up → Vol Down → hold Side button until Apple logo (about 10 seconds)
- iPhone 7: Hold Side + Vol Down until Apple logo
- iPhone 6s and earlier: Hold Home + Side until Apple logo
- iPad with no Home button: Same as iPhone 8+
- iPad with Home button: Hold Top + Home until Apple logo
Step 3: Try a Different Cable + Adapter + Outlet
Often the device IS charging but the indicator doesn't show due to a bad cable. Try at least 2 different cables and 2 different power sources.
Step 4: Inspect the Charging Port
Lint can completely block charging. With a flashlight, look for compacted gray fuzz at the back of the port. Use a plastic pick (never metal) to clear it.
Step 5: Recovery Mode Restore
If force restart doesn't bring it back: connect to a Mac/PC, open Finder (or iTunes on PC), put the device in Recovery Mode, and click Update (NOT Restore — Update preserves your data).
- iPhone 8+: connect to computer, press Vol Up + Vol Down + hold Side until Recovery Mode screen
- iPad without Home: same as iPhone 8+
- iPad with Home: hold Top + Home until Recovery Mode screen
Step 6: Check for Liquid Damage
Look at the SIM tray slot — there's a small white strip inside. If it's red/pink, the device has been wet. Even drops of moisture can prevent boot. Place in silica gel for 24+ hours, do NOT power on, and try again.
⚠️ Common Mistakes to Avoid
- Assuming it's broken after only 5 minutes of charging
- Skipping force restart and going straight to Apple
- Using random USB cables (counterfeit ones don't deliver enough power)
- Powering on after liquid exposure (causes corrosion)
🏥 When to Call a Pro
If the device shows no signs of life after force restart + recovery-mode restore + clean port + 1 hour charge, you have a hardware issue. Apple diagnoses for free at the Genius Bar. Logic board issues run $300–$700 to fix; sometimes replacement is cheaper than repair.
⚡ Fix #1: Force Restart
Always try this first — it works surprisingly often:
iPhone 8, X, 11, 12, 13, 14, 15, 16:
- Press and quickly release Volume Up
- Press and quickly release Volume Down
- Press and hold Side button until you see the Apple logo
- Keep holding even if you see "slide to power off"
- Release when Apple logo appears
iPhone 7:
- Press and hold both Volume Down + Power
- Hold until Apple logo appears (10+ seconds)
iPhone 6s and earlier:
- Press and hold both Home + Power
- Hold until Apple logo appears (10+ seconds)
🔌 Fix #2: Charge Your iPhone
Low battery can cause boot loops:
- Connect to a wall charger (not computer USB)
- Use Apple or MFi-certified cable
- Wait at least 30 minutes
- Try force restart again
Tip: If you see a red battery icon, your phone was critically low. Charge for at least an hour before trying anything else.
🍏 Fix #3: Update iOS via Recovery Mode (Keeps Data)
This reinstalls iOS without erasing your data — try this before restoring:
- Connect iPhone to computer with iTunes (Windows) or Finder (macOS)
- Put iPhone in Recovery Mode:
- iPhone 8+: Volume Up (tap), Volume Down (tap), hold Side button until Recovery screen
- iPhone 7: Hold Volume Down + Power until Recovery screen
- iPhone 6s-: Hold Home + Power until Recovery screen
- You'll see a "connect to computer" screen on iPhone
- Computer will show "Update or Restore" prompt
- Click "Update" (NOT Restore)
- Wait for download and installation (can take 15-30 min)
Important: "Update" keeps your data. "Restore" erases everything!
💾 Fix #4: Restore iPhone (Last Resort)
If Update fails, you may need to restore. This erases everything:
- Put iPhone in Recovery Mode (same steps as above)
- Click "Restore" when prompted
- Wait for iOS to download and install
- Set up as new or restore from backup
⚠️ Warning: This deletes all data on your iPhone. Only do this if you have a backup, or if Update didn't work.
🔧 Fix #5: DFU Mode Restore (Deepest Reset)
DFU (Device Firmware Update) mode is the most complete restore:
iPhone 8 and newer:
- Connect to computer
- Press Volume Up (tap), Volume Down (tap)
- Hold Side button until screen goes black
- When black, hold Side + Volume Down for 5 seconds
- Release Side button, keep holding Volume Down for 10 seconds
- Screen stays black but computer detects iPhone
- Restore in iTunes/Finder
iPhone 7:
- Connect to computer
- Hold Power + Volume Down together for 8 seconds
- Release Power, keep holding Volume Down for 5 seconds
- Screen stays black, computer detects iPhone
iPhone 6s and earlier:
- Connect to computer
- Hold Power + Home together for 8 seconds
- Release Power, keep holding Home for 5 seconds
- Screen stays black, computer detects iPhone

Note: Be cautious with third-party tools. Use reputable software only and research before downloading.
