You press the Side button and either nothing happens at all, or the Apple logo appears — and stays there, sometimes flickering, sometimes rebooting itself in an endless loop. It's one of the most stressful iPhone problems because it can mean two very different things: a quick software fix you can do in your kitchen in the next 20 minutes, or a hardware failure that puts years of photos, messages, and documents at risk. This guide walks through every fix in the correct order, from the fastest checks to DFU mode, and explains exactly how to tell when it's time to stop trying and call a specialist.
Quick answer
If your iPhone is stuck on the Apple logo, a force restart clears it in most cases within seconds — and if it doesn't, a Recovery Mode or DFU restore through Finder/iTunes fixes the majority of the rest. If the screen is completely black with zero response even after 30 minutes on a wall charger, check the cable, adapter, and charging port before assuming the worst. If none of these steps work and the phone was recently dropped, wet, or overheated, the logic board is the likely cause — stop trying to power it on and call a data recovery specialist before you lose access to what's on it.
Quick Checks Before You Start
Before working through the full fix list, eliminate these simple causes — they resolve a surprising number of cases in under five minutes.
- Check the battery isn't just dead: Plug into a wall outlet — not a laptop USB port — with an Apple-certified cable and leave it alone for 15-30 minutes. A fully drained battery can take that long to display anything at all, including the charging screen.
- Try a different cable, adapter, and outlet: A worn Lightning or USB-C cable is one of the most common causes of "iPhone won't turn on" calls. Swap in a cable and adapter you know works on another device.
- Inspect the charging port with a flashlight: Lint, pocket dust, or debris in the charging port can block a proper connection. Look closely before assuming a hardware failure.
- Check for visible damage: A swollen back panel (battery swelling), a screen that's separating from the frame, or a cracked back near the camera can indicate a physical problem that a software fix won't solve.
60-Second Triage Checklist
- Plugged into a wall outlet (not a computer) with a known-good cable for at least 15 minutes
- Tried a second cable and a second wall adapter
- Charging port checked with a flashlight for lint or debris
- No visible swelling, cracking, or separation of the back panel or screen
- No recent drop, liquid exposure, or extreme heat/cold before the issue started
- Force restart attempted (see Fix 1 below) and given a full 20 seconds to take effect
Fix 1 — Force Restart Your iPhone
A force restart is the digital equivalent of pulling a plug and plugging it back in — it clears a frozen or hung system state without erasing any data. This is always the first thing to try, whether your phone is boot-looping on the Apple logo or shows nothing at all.
iPhone 8 and later (including iPhone X through 16 Pro Max)
Quickly press and release the Volume Up button. Quickly press and release the Volume Down button. Then press and hold the Side button until the Apple logo appears — this can take 10-20 seconds. Ignore the "slide to power off" screen if it appears; keep holding through it.
iPhone 7 / 7 Plus
Press and hold both the Volume Down button and the Side (Sleep/Wake) button at the same time for at least 10 seconds, until the Apple logo appears.
iPhone 6S and earlier (with a Home button)
Press and hold both the Home button and the Side/Top button at the same time for at least 10 seconds, until the Apple logo appears.

Fix 2 — Rule Out a Charging Problem
A significant share of "iPhone won't turn on" calls turn out to be a charging issue rather than a dead phone. Before assuming the worst, eliminate the cable, adapter, outlet, and port one at a time.
Swap the Cable and Adapter
Use a cable and wall adapter that you know works on another iPhone or device. Frayed or internally broken Lightning and USB-C cables are extremely common and often show no visible damage.
Clean the Charging Port
Using a flashlight, look into the charging port for lint, pocket dust, or debris — this is one of the most common and most overlooked causes. Gently clean with a dry anti-static brush or a wooden toothpick. Never use metal objects or compressed air aimed directly into the port, which can push debris deeper or damage internal pins.
Try a Different Wall Outlet
Some outlets, especially those on a switch or a power bar, may not be delivering power. Test a completely different outlet in another room before ruling out charging entirely.
Fix 3 — Recovery Mode Restore (Finder or iTunes)
If a force restart doesn't clear the Apple logo boot loop, Recovery Mode gives Finder (on a Mac, macOS Catalina or later) or iTunes (on a PC, or older Mac) direct access to reinstall iOS. This resolves the majority of remaining boot loop cases caused by a corrupted update or a failed jailbreak/profile install.
Connect and Enter Recovery Mode
Connect your iPhone to a computer with a cable. Open Finder (Mac) or iTunes (PC). Perform the same force restart sequence for your model (see Fix 1), but this time keep holding the Side button after the Apple logo appears — do not release it. Continue holding until you see the "Connect to Computer" / Recovery Mode screen instead of the Apple logo.
Choose Update (Not Restore) First
Finder or iTunes will prompt you to Update or Restore. Always try Update first — this reinstalls iOS and attempts to preserve your data. Only choose Restore if Update fails, since Restore erases the device completely and reinstalls iOS from scratch.
Stuck Before You Even Get to Restore?
IT Cares fixes boot loops and DFU restores remotely or in-person — from $119.99. No fix = no charge.
Fix 4 — DFU Mode (Device Firmware Update)
DFU mode is the deepest, lowest-level restore state an iPhone has — it loads the device below iOS, at the firmware level, which is why it can succeed when a normal Recovery Mode restore fails. It's the last software fix to try before hardware becomes the likely explanation.
Enter DFU Mode (iPhone 8 and later)
Connect the iPhone to a computer with Finder or iTunes open. Quickly press and release Volume Up. Quickly press and release Volume Down. Press and hold the Side button until the screen goes completely black — about 5 seconds. Without releasing the Side button, also press and hold Volume Down for 5 seconds. Then release the Side button only, continuing to hold Volume Down, until Finder or iTunes shows a message that it has detected an iPhone in recovery mode / DFU mode.
The Screen Stays Black — This Is Normal
Unlike Recovery Mode, DFU mode shows nothing on the iPhone's screen at all — no logo, no cable icon. This is expected. Confirm you're in DFU mode by checking that your computer, not the iPhone, shows the detection message.
Causes and Fixes — Comparison Table
Use this table to match your symptoms to the likely cause, the right fix, and whether it's worth attempting yourself or time to call a specialist.
| Symptom | Likely Cause | Recommended Fix | DIY or Specialist? |
|---|---|---|---|
| Apple logo appears, phone restarts on a loop | Failed iOS update or corrupted system file | Force restart, then Recovery Mode / DFU restore | DIY first |
| Nothing happens at all when plugged in | Dead battery, bad cable, or faulty adapter | New cable + wall outlet, wait 30 min | DIY first |
| Charges but screen never lights up | Charging port debris or display connector issue | Clean port, try force restart; if not, in-person check | DIY then specialist |
| Won't turn on after being dropped | Logic board flex, cracked display connector | Stop use immediately, in-person diagnostic | Specialist |
| Won't turn on after water/liquid exposure | Corrosion on logic board or NAND chip | Power off, no heat, ship/bring in immediately | Specialist — urgent |
| Overheats, then shuts off and won't restart | Battery failure or thermal shutdown from a fault | Let cool, do not force-charge repeatedly, in-person check | Specialist |
| DFU restore completes but phone still won't boot | Physical NAND/logic board failure | Data recovery diagnostic before further attempts | Specialist |
| Back panel visibly swollen or bulging | Swollen battery (safety risk) | Stop charging immediately, in-person only — do not puncture | Specialist — urgent |
When It's a Hardware Failure — Signs to Watch For
If you've tried a force restart, Recovery Mode, and DFU mode without success, hardware is the most likely remaining explanation. Here are the clearest indicators:
- Recent drop, water exposure, or extreme heat: If the failure started right after a physical event, that event is almost certainly the cause, regardless of what software steps you try.
- Both Recovery Mode and DFU restores fail: Two independent, deep-level restore paths failing points strongly to the NAND chip or logic board rather than iOS itself.
- Swollen back panel: A bulging or lifted screen/back glass is a swollen battery — a safety hazard as well as a hardware failure. Stop charging it and do not press on the swelling.
- The device gets hot while stuck: Unusual heat during a failed boot attempt, especially near the camera or charging port, suggests a short circuit rather than a normal software crash.
- Visible corrosion or discoloration: Check the SIM tray and charging port with a flashlight — greenish or white residue indicates past liquid exposure, even if the phone was never visibly "wet" when it happened.
What This Costs — Software Fix vs. Repair vs. Data Recovery
Costs vary widely depending on whether the issue is software, a hardware repair, or a data recovery case. Here's what to budget for each scenario in Canada.
| Scenario | What's Involved | Typical Cost |
|---|---|---|
| Software fix (force restart, DFU restore) | Self-service, or guided remote support | Free (DIY) or from $119.99 (guided) |
| Battery replacement (swollen/dead battery) | In-person part swap | $99–$150 |
| Charging port repair | In-person cleaning or port replacement | $80–$180 |
| Screen/display connector repair | In-person part swap | $150–$300 |
| Data recovery — logical failure (software-level, hardware intact) | $49 diagnostic, then recovery | $349 |
| Data recovery — physical failure (water, drop, logic board) | $49 diagnostic, then chip-level extraction | $799 |
The $49 diagnostic at IT Cares applies toward any recovery cost and gives you a written answer on what's recoverable before you commit to the $349 or $799 tier — see our full iPhone Data Recovery Cost Explained guide for a deeper breakdown by model and failure type.
Canadian Case Studies
Three real-pattern scenarios from IT Cares' Montreal lab, representative of the calls we handle every week across Canada.
iPhone 13 stuck on Apple logo after an iOS update
A Toronto client's iPhone 13 restarted itself every 15 seconds, always stopping at the Apple logo, after an overnight iOS 17 update. A force restart didn't fully clear it — the loop resumed within a minute. A Recovery Mode restore through Finder, choosing Update rather than Restore, fixed it completely with no data loss. Total time: about 25 minutes, no cost since the client had a Mac and did it themselves after a phone consultation with IT Cares.
iPhone 14 Pro dropped in a sink, powered on once, then went dead
A Halifax client's iPhone fell into a sink of soapy water. It was retrieved and, out of instinct, powered on to "check if it worked" — it briefly showed the Apple logo, then went permanently black. Powering it on while wet activated corrosion on the logic board. IT Cares performed a $799 chip-level NAND extraction after ultrasonic cleaning and ~90% of the client's photos and messages were recovered. Lesson: never power on a wet iPhone, even briefly — see our water damaged device recovery guide for first-aid steps that apply to phones too.
iPhone 12 "wouldn't turn on" for two days
A Calgary client assumed their iPhone 12's battery or logic board had failed after two days of trying various chargers with zero response. A quick flashlight inspection during a remote video consultation revealed heavy pocket lint packed into the charging port, blocking any real contact with the cable pins. A gentle cleaning with a wooden toothpick resolved it in under two minutes — no charge, since this fell under a free phone consultation.
What to Do Right Now
Work through the fixes in this order: force restart, charging checks, Recovery Mode restore, then DFU mode. If none of them work — or if the iPhone was recently dropped, wet, or overheated before the issue started — stop attempting further restores. Every additional power cycle on a physically damaged board reduces the odds of a clean data recovery.
Call IT Cares at 1 (888) 711-9428 and we'll walk through your exact symptoms over the phone in a few minutes, tell you whether it's worth attempting DFU mode yourself or bringing it in immediately, and give you a written diagnostic for $49 before you commit to any repair or recovery cost.

Frequently Asked Questions
An iPhone stuck on the Apple logo (boot loop) is usually caused by a failed iOS update, a corrupted system file, or a full storage drive interrupting the boot process. In most cases this is a software issue fixed with a force restart or a restore through Recovery Mode/DFU mode. If the loop continues after a full DFU restore, the logic board or NAND storage chip may be physically damaged.
On iPhone 8 and later: quickly press and release Volume Up, quickly press and release Volume Down, then press and hold the Side button until the Apple logo appears (10-20 seconds). On iPhone 7/7 Plus: hold Volume Down and the Side button together. On iPhone 6S and earlier: hold Home and the Side/Top button together. This forces a restart without erasing any data.
Not necessarily. Plug into a wall outlet (not a laptop USB port) with an Apple-certified cable and wait 15-30 minutes — a fully drained battery can take time to show any screen. If there's zero response after 30 minutes on a known-good cable, adapter, and outlet, the charging port, battery, or logic board may have failed, requiring an in-person diagnostic.
DFU (Device Firmware Update) mode is the deepest recovery state on an iPhone, used when Recovery Mode restores fail. It loads the iPhone at the firmware level, below iOS, allowing Finder or iTunes to reinstall the operating system from scratch. The screen stays completely black during DFU mode — that's expected, not a bigger problem.
Yes. A DFU restore wipes the iPhone and reinstalls iOS fresh. If you have a recent backup, your data can be restored after. If you don't have a backup and the phone still has unique data on it, don't restore through DFU mode — a data recovery specialist needs to extract the data first, before the drive is overwritten.
Signs pointing to hardware: the phone was dropped, wet, or overheated right before the issue started; a force restart and full DFU restore both fail; the phone charges but never shows any screen activity, even the Apple logo; or it gets unusually hot while stuck. Software issues typically respond to a force restart or DFU restore within 30-60 minutes.
In many cases, yes. If the failure is logical (corrupted iOS, failed update), the NAND storage is usually intact and recoverable — $349. If the failure is physical (water, drop, logic board), chip-level extraction is required — $799. IT Cares offers a $49 diagnostic to confirm which applies first, with a no-data-no-pay guarantee. See our full iPhone data recovery cost breakdown.
A software-level fix (force restart, DFU restore) is free if you do it yourself, or starts from $119.99 with guided remote support. Hardware repairs like a battery or charging port typically run $120-$300. If data recovery is required, IT Cares charges $349 for logical recovery and $799 for physical/chip-level recovery, with the $49 diagnostic applied first.
Comments
Force restart fixed my iPhone 15 immediately — I'd never done the Volume Up, Volume Down, hold Side button sequence before and didn't realize it was different from just holding the power button. Was stuck on the Apple logo for two days thinking I'd need a new phone. Took 20 seconds once I did it right.
Turned out to be lint in the charging port on my iPhone 11 — I was convinced the battery was dead after two days of nothing happening. The flashlight trick in this guide showed a huge clump of pocket fluff. Cleaned it with a toothpick and it charged right away. Wish I'd checked that first before panicking.
