How to Force Restart Your iPhone and Use Recovery & DFU Mode
When your iPhone experiences software or firmware issues, understanding how to troubleshoot effectively can save you significant time and effort. The video below from
Daniel About Tech provides clear instructions on how to force restart your device, enter and exit recovery mode, and use DFU (Device Firmware Update) mode. These techniques are essential for resolving common problems without risking data loss, provided no restoration is performed.
Force Restarting Your iPhone
A force restart is a straightforward and effective method to address minor software glitches or unresponsive behavior. This process interrupts the current power cycle and reboots your device without requiring a computer. Follow these steps to perform a force restart:
Quickly press and release the volume up button.
button. Quickly press and release the volume down button.
button. Press and hold the side button until the Apple logo appears on the screen.
This method is particularly useful for resolving temporary issues such as frozen apps, unresponsive screens, or minor software malfunctions. It is safe to perform and does not affect your data or settings.
Entering and Exiting Recovery Mode
Recovery mode is a more advanced troubleshooting tool designed to address persistent iOS software issues. It allows you to restore your iPhone's operating system using a computer. To enter recovery mode, follow these steps:
Connect your iPhone to a computer using a Lightning cable. Ensure the computer has the latest version of iTunes (Windows) or Finder (macOS).
Perform the force restart sequence: press and release the volume up button, press and release the volume down button, and then press and hold the side button .
button, press and release the button, and then press and hold the . Continue holding the side button until the recovery mode screen appears. You will see an image of a cable pointing to a computer.
To exit recovery mode, press and hold the side button for approximately 15 seconds while the iPhone remains connected to the computer. The device will restart and return to its normal operating state.
Recovery mode is ideal for resolving issues such as failed updates, persistent software bugs, or problems that prevent your iPhone from booting up properly.
Entering and Exiting DFU Mode
DFU (Device Firmware Update) mode is the most advanced troubleshooting option available for iPhones. It allows you to restore both the iOS software and the device firmware, making it particularly useful for addressing severe issues such as corrupted firmware or failed updates. Here's how to enter DFU mode:
Connect your iPhone to a computer using a Lightning cable.
Quickly press and release the volume up button.
button. Quickly press and release the volume down button.
button. Press and hold the side button for 10 seconds.
for 10 seconds. While holding the side button, press and hold the volume down button for 5 seconds.
button for 5 seconds. Release the side button but continue holding the volume down button until the computer detects the iPhone in DFU mode. The screen will remain black.
To exit DFU mode, perform the force restart sequence while the iPhone is still connected to the computer. This will return the device to its normal operating state.
DFU mode is a powerful tool for resolving complex issues, but it should be used with caution. Unlike recovery mode, it bypasses the iOS bootloader, allowing for deeper-level troubleshooting.
Key Differences Between Recovery and DFU Modes
Understanding the differences between recovery and DFU modes is essential for selecting the appropriate troubleshooting method. Here are the key distinctions:
Recovery Mode: This mode is primarily used to restore iOS software. It is suitable for resolving issues such as failed updates, persistent software bugs, or problems that prevent the device from booting normally.
This mode is primarily used to restore iOS software. It is suitable for resolving issues such as failed updates, persistent software bugs, or problems that prevent the device from booting normally. DFU Mode: This mode allows for the restoration of both iOS software and firmware. It is a more comprehensive option, ideal for addressing severe problems such as corrupted firmware, hardware-related issues, or failed system updates.
Both modes require a computer with the latest version of iTunes (Windows) or Finder (macOS) to function properly. Choosing the correct mode depends on the severity and nature of the issue you are attempting to resolve.
Important Considerations
Before using recovery or DFU mode, keep the following points in mind to ensure a smooth troubleshooting process:
Neither recovery mode nor DFU mode will erase your data unless you choose to perform a restoration. However, it is always advisable to back up your data regularly.
Ensure your computer has the latest version of iTunes or Finder to avoid compatibility issues during the process.
These methods are safe and effective for resolving most software-related problems on iPhones, provided they are performed correctly.
By mastering these troubleshooting techniques, you can take control of your iPhone's functionality and address a wide range of issues efficiently. Whether you are dealing with minor glitches, failed updates, or more complex software problems, these steps provide reliable solutions to restore your device to optimal performance.

I've tested over 50 wireless earbuds — here are the best for fitness, noise-cancelling and more
I'm using wireless earbuds constantly. I'm tuning out noise on the subway to listen to a podcast. I'm taking calls at work. I'm listening to music while I work out. I always have a pair in my bag or my pocket. But there are so many options on the market, making it hard to know which is best for you and your needs. As NBC Select's tech reporter, I test earbuds on an almost monthly basis. Below are some of the best of the best for all kinds of activities and budgets. How I test wireless earbuds I try new earbuds all the time, incorporating them into my daily routine. That means office work, video calls, subway commutes, outdoor runs, indoor gym time and watching videos on my phone, tablet or laptop. While using earbuds, I pay close attention to the following: Comfort: A pair of earbuds is only useful if you feel comfortable wearing them for hours at a time. I wore earbuds for upwards of 3 hours to get a feel for long-term comfort. I also tried different-sized ear tips to find my ideal fit. Everyone's ears are a little different. If the earbuds don't fit comfortably right out the box, try different eartips to get a more comfortable fit. Noise cancellation: I used each pair of earbuds for my office commute on the NYC subway. I also used them in-office to block out background noise and conversations. Sound quality: I listened to the same music playlist with each pair of earbuds to identify differences in sound quality and instrumentation. Ease of use: When trying earbuds, I used the on-ear controls to take calls, play media and more. I also downloaded each brand's mobile app, noting how easy it was to use and the utility offered. Some earbuds let you connect to multiple devices at the same time, this is called Bluetooth multipoint — I tried this feature with my phone, tablet and laptop when available. Battery life: I tried each pair of earbuds for at least a week. Throughout that period, I paid attention to how many times I needed to charge them. The best wireless earbuds After trying out dozens of earbuds, my top picks came from brands like Apple, Google, Beats, Bose and Shokz. If you own an iPhone, these are the earbuds to get. They are comfortable, have excellent sound quality and noise cancellation. They are also good for basically any activity you throw at them including outdoor runs and workouts. With noise cancellation turned on, chatter and music at the gym fade instantly, in my experience. With transparency mode on, I can hear my surroundings very clearly, perfect for running outdoors. AirPods Pro 2 also includes four ear tip sizes in the box, more than most brands, which can help you get a more comfortable fit for your ears. The buds also have great on-ear controls, including a swipe on the ear stem to control volume. If all of this sounds good to you, but you can't stand rubber eartips clogging your ears, consider Apple AirPods 4 ANC instead. They have similarly great sound and call quality, but leave your ears more open because they don't have rubber eartips. However, this does mean the noise cancellation is less effective than AirPods Pro 2, in my experience. Anyone with an Android phone looking for one pair of do-it-all earbuds should consider these latest Google Pixel buds. The new design has a mini wing-tip stabilizer in each ear that fits snugly and makes them stable and secure for workouts. 'They are comfortable and don't hurt the inside of my ear within an hour of wearing them,' says NBC Select commerce editor Cory Fernandez. You don't need to spend hundreds of dollars to get fully featured earbuds — these have active noise canceling, transparency mode, Bluetooth multipoint and wireless charging, all for under $100. They are comfortable, sound surprisingly good and can compete with earbuds that are much pricier. The only downside is noise cancellation — it's okay, but isn't very useful against plane, train and car noise. The Liberty 4 NC is not the brand's latest model, and while I would love to recommend the newer Anker Soundcore Liberty 5, which are excellent, they are $130, which I don't consider 'budget.' These are some of the most affordable wireless earbuds that still deliver a steady Bluetooth connection, surprisingly good sound quality and a convenient charging case. The earbuds and case have a combined battery life of around 32 hours, and the case has a cable built-in for convenient recharging. If you purchase the earbuds from the brand's website, you can choose from 13 bright and earth-tone colorways. They don't have active noise canceling or transparency modes, and the app is a little lackluster, but these are fair trade-offs for such a low price. If your top priority is blocking out background noise like the hum of a plane cabin, rattling train cars and water cooler talk, these earbuds are for you. They have the best noise cancellation of any earbud I've tried, full stop. Plus they sound amazing, with detailed instrumentation in music and clear audio in TV shows and movies. They are big earbuds, though — I don't find them particularly comfortable for fitness and exercise. They are also pricey at $300. If you're willing to sacrifice a little noise cancelling power, consider the Bose QuietComfort Earbuds as a more affordable runner-up. The Beats Fit Pro have been one of my go-to workout headphones for years and remain a favorite after all this time. The wing-tip design creates a secure fit that never faltered during runs, bike rides or gym time. But unlike full ear-hook earbuds, the Beats Fit Pro case is just small enough to be pocketable. Both earbuds have physical button controls that are easy to use, even when I am wearing thick gloves during a winter run. You can press either button to stop, start and skip songs, and holding the button changes between noise cancellation and transparency mode. The Beats Fit Pro pairs easily with my iPhone and I have a similar experience on Android using the Beats mobile app. The Beats Fit Pro are dated, though. They originally launched in 2021, and are due for an upgrade. Open earbuds rest on the outside of your ear instead of going inside of your ear canal. I use them on bike rides while NBC Select editorial director Lauren Swanson uses them for runs and races like the New York City Marathon — it makes it easier to hear nearby cars, bikes and pedestrians. While I'm partial to the Shokz OpenRun Pro 2, I admit that the more versatile option for everyday use is the Shokz OpenFit 2. They are small and comfortable, have great sound quality (for open earbuds) and fit in a relatively pocketable charging case. But, like with any pair of open earbuds, don't expect them to block any noisy neighbors while working out at the gym. A newer offshoot of open earbuds is clip-on earbuds. These earbuds wrap around your outer ear like an ear cuff, leaving your ear canal open and the top of your ears free for things like glasses and hats. The Bose Ultra Open Earbuds are some of the best clip-on earbuds I've tried (with a price tag to match). They don't look very secure at a glance, but after multiple 5Ks and 15 plus mile bike rides, they are some of the most secure open earbuds you can get. They are also comfortable, lightweight and unobtrusive — I wore them for a full day and forgot they were on my ears multiple times. Clip-on earbuds don't have the best sound quality — the speakers are further away from your ears. While audio quality on the Ultra Open Earbuds is good, call quality isn't great. You can learn more in my Bose Ultra Open Earbuds review. , JLab Flex Open or Soundpeats Pop Clip earbuds instead — they are all much cheaper, but have a similar shape and size to the Ultra Open. The Beats Powerbeats Pro 2 are some of the most secure workout headphones I've ever tested. The earhook design and general fit take a minute to set into your ear, but once they're settled, they are rock solid and don't budge no matter what I am doing. The earbuds have noise cancellation and transparency modes, on ear media and volume controls, a wireless charging case and work well on both iPhone and Android devices. They also have built-in heart rate sensors in each earbud, and while a little finicky to sync, they are nice to have if you don't already use a fitness tracker or smart ring. You can read more in my Beats Powerbeats Pro 2 review. My previous earhook pick, the JBL Endurance Peak 3, is still a great option if you are looking for something simple, secure and less pricey. Best cheap earhook: For $30, I was surprised by the quality of these earbuds. They have a large ear hook design that wraps around the back of your ears — I found them to be tight and comfortable, but not so snug that I couldn't hear traffic noise or other runners around me. Plus they have a transparency mode and customizable settings through the JLab app. I think these are best as a second pair of earbuds you use specifically for working out or going for a run. You can be a little more carefree with a $30 pair of earbuds than a $300 pair. How to shop for wireless earbuds There are hundreds of wireless earbuds on the market. Some can look almost identical, but they can vary wildly in features and price. Below are a few factors to keep in mind while shopping for a new pair. Operating System (iPhone and Android) Not all wireless earbuds play nice with both Apple and Android devices. If you use Apple AirPods on an Android device, for example, most of their features will be difficult or impossible to use. Earbuds that work well on both platforms tend to have useful standalone apps that can help control noise cancellation, audio equalization and more. Automated noise canceling and transparency Noise canceling and transparency modes are both useful features that add versatility to any pair of earbuds. Noise canceling blocks outside sound, while transparency mode lets sound in so you can better hear the noise around you, a useful safety feature for activities like outdoor running. Cheaper earbuds (under $100) may have one or both built-in, but generally don't perform as well as pricier options. (under $250). Water and dust resistance Water and dust resistance is indicated by an earbud's IP (ingress protection) rating. IP ratings are denoted with two numbers, for example, IP55. The first digit represents intrusion protection against dust and debris. The second digit denotes moisture protection. If you want to wear your earbuds in wet and rainy conditions, get a pair with a higher IP rating, they are less likely to malfunction in bad weather. Why trust NBC Select?

Lymow One: The Boundary-Free Robot Mower That Finally Tackles Real Lawns
If you've ever tried a robot mower only to pull it out, dusty and defeated, you're not alone. Most legacy models hobble around with boundary wires, low wheels, and shaky navigation. Enter the Lymow One—a wire-free powerhouse built to take on slopes, obstacles, and sprawling lawns. It's already pulled in over $7 million on Kickstarter, and for good reason. Watch this video on YouTube. Pro-Grade Cuts, No Compromises Lymow One's front-mounted cutting deck isn't just for show—it's engineered for serious mowing performance. At the core is the LYCUT system, a dual-blade setup spinning at 6000 RPM, paired with a high-speed centrifugal fan to keep clippings from clumping. Need a precise cut? You can dial in the mowing height from 1.2 to 4 inches to match your lawn's exact vibe. 9× More Efficient Than Typical Robotic Mowers While most robotic mowers crawl around at a snail's pace, Lymow One covers serious ground. With a 16-inch cutting width and up to 3.3 ft/s mowing speed, it can mow up to 0.57 acres on a single charge—the same job that takes other bots all day.

Real Mulching for a Healthier Lawn Lymow One doesn't just cut—it feeds your lawn. The mulching blades finely chop clippings into nutrient-rich bits, while a 27 mph centrifugal fan disperses them evenly and prevents clogging. That means healthier growth, cleaner finishes, and less post-mow mess. Tank Tracks for Terrain Mastery Let's be real—most lawns aren't pristine golf courses. Slopes, roots, and soft spots are part of the deal. Lymow One's rugged tracked drive system tackles slopes up to 45° (100%)—the steepest of any robot mower on the market. With 2 inches of ground clearance, it powers through uneven terrain, twigs, and bumps without getting stuck. If your yard has hills, dips, or areas that stay squishy after rain, this is the mower that keeps going while others spin their wheels. Smarter Navigation That Doesn't Get Lost Lymow One isn't just smart—it's situationally aware. While most robotic mowers struggle in complex environments, Lymow One combines multiple navigation systems to stay on course, avoid trouble, and deliver consistent results. Reliable Navigation The RTK (Real-Time Kinematic) system gives Lymow One centimeter-level GPS precision in open areas, while VSLAM (Visual Simultaneous Localization and Mapping) takes over near trees, fences, or buildings where GPS alone can't cut it. The result? Flawless pathing, even in complex, cluttered lawns.

Full App Control from Anywhere With the Lymow app, everything you need is right at your fingertips. Schedule mow times, manage zones, set no-go areas, adjust cutting height, and monitor progress—all from your phone. If the mower leaves its geo-fenced area, you'll get instant alerts and can remotely lock the device if someone tries to take it off your property. Built Rugged for the Long Haul Lymow One is built for serious use, not just sunny weekends. It features a die-cast aluminum frame optimized with FEM engineering, IPX6 waterproofing, and a 300W intelligent brushless motor that dynamically adjusts for performance and longevity. It's powered by a LiFePO₄ battery—the gold standard in safety and longevity—capable of over 2,000 recharge cycles in lab tests. Translation? This mower is in it for the long game. Advanced Safety Features That Just Make Sense Lymow One is designed to mow smart—and stop smarter. Its multi-layered safety system ensures peace of mind on every run: Sees and Reacts Intelligently AI vision with semantic recognition and depth sensing helps Lymow One identify objects and avoid trouble, while ultrasonic sensors and a responsive bumper prevent collisions before they happen.
