How To: The Ultimate Guide to Using TWRP: The Only Custom Recovery You'll Ever Need

Just the fact that you own an Android device means you're privy to an entire world of third-party development. Many of the mods you'll see here on Gadget Hacks can be performed fresh out of the box, but with root and Xposed, the list grows longer. But to truly be able to take advantage of all that Android's massive development community has to offer, you'll need to have a custom recovery installed.

Hack Like a Pro: How to Create a Nearly Undetectable Covert Channel with Tunnelshell

Welcome back, my rookie hackers! Most often, the professional hacker is seeking protected information from the target system or network. This might be credit card numbers, personally identifiable information, or intellectual property (formulas, plans, blueprints, designs, etc.). Most of my Null Byte guides have been focused on getting into the system, but this only begs the question—"what do I do when I get there?"

How To: Control Your Nexus 5 Without Touching the Screen

If you've ever seen one of those Samsung commercials from about a year back, you know that the Galaxy S series of phones come with a feature that allows you to do certain things by making gestures in front of your screen.

How To: Get Your HTC One M7 Ready for a Different Mobile Carrier

Whether it's spotty data coverage, bad customer service, or a high monthly bill, at some point many of us consider changing carriers. The problem is, we often don't want or need to change our devices. Since it's now legal to unlock devices to bring to new carriers, getting devices switched over is doable, but it's pain going into carrier stores and dealing with their constant upselling.

How To: 12 April Fool's Day Pranks for Your Smartphone-Addicted Family & Friends

April Fool's Day, aka National Screw with Your Friends Day, is finally here. You can always pull a conventional prank, like strategically placing a whoopee cushion on your mom's chair, but that joke has been exhausted generations before smartphones were around.

How To: Make Crappy Wine Taste Good & Good Wine Taste Better Without Any Special Tools

Letting wine "breathe" isn't just something that happens in restaurants in '80s teen comedies with snooty maître d's. It's really a thing, and you should learn how to do it at home, because it'll make just about any wine—including Two-Buck Chuck—taste much, much better. It's also astonishingly easy, and despite what the Home Shopping Network may tell you, does not require buying extra gadgets.

Hack Like a Pro: How to Hack into Your Suspicious, Creepy Neighbor's Computer & Spy on Him

Welcome back, my neophyte hackers! Have you ever had a neighbor that you're certain is up to no good? Maybe you've seen him moving packages in and out at all hours of the night? Maybe you've seen people go into his home and never come out? He seems like a creep and sometimes you hear strange sounds coming from his home? You know he's up to no good, but you aren't sure what it is exactly.

How To: Understanding Signature Schemes: How Data Sources Are Authenticated, Secured, & Spoofed

One of the biggest problems in data security is authentication of data and its source. How can Alice be certain that the executable in her inbox is from the venerable Bob, and not from the not-so-venerable Oscar? Clearly Alice wants to know because if this file is actually sent to her by Oscar, the file might not be a game, but a trojan that can do anything on her computer such as sift through her email and passwords, upload her honeymoon pictures, or even turn on microphones and webcams. Thi...

How To: Inflate Any Ball Without a Pump or Needle

What happens when you find your ball deflated and there's no pump or needle in sight? You could always cancel your plans of kicking around the soccer ball or starting that pickup football game in the park. Better yet, you could be terribly clever and find another way to get air into the ball. From a pen to a balloon to a gas station, there are ways to inflate it.

The Time Traveler's Companion: Surviving the Past and Future with Your Kindle

Not that long ago I wrote an article discussing what it would be like, realistically, if you were to accidentally travel back in time to the Victorian era. At the end of that article, I mentioned that the best thing you could bring with you on a time-traveling adventure is a Kindle, or similar e-reader, stuffed full of the knowledge of the 21st century. Why a Kindle? Well, I own a Kindle, and I love it. However, there's far more to it than that.

How To: Planning on Buying an iPhone 5? Here's How to Get the Most Money for Your Old iPhone 4 or 4S

Apple is notoriously cryptic when it comes to the reveals of its new products, and as usual, they've kept us guessing about the release of the iPhone 5 (or "New iPhone?"). It's expected to be officially revealed on September 12, and rumor has it that sales will begin on the 21st. Though the whole world seems to be anxiously awaiting the announcement, there has also been some controversy surrounding the iPhone 5's production.
