DFU

Security researchers demonstrate ‘PlugNPwn’ attack on T2-equipped Mac

It wasn’t long after the checkm8 bootrom exploit gave rise to the checkra1n jailbreak tool that clever hackers learned how they could use the same exploit (along with other hacks) to tamper with the proprietary T2 chip embedded in a bevy of modern Macs. In fact, the checkra1n jailbreak tool’s most recent update even added support for the T2 chip in Macs for interested tinkerers.

Despite how incredible the aforementioned circumstances sounded to jailbreak enthusiasts at first glance, those on the other side of the fence quickly began wondering about the implications this might have for the security of Apple’s most popular computers. Now, we may finally have some idea thanks to information published by the t8012 Development Team.

New solder-on cable allegedly permits DFU mode entry on Apple TV 4K

One of the most substantial things to happen in the jailbreak community in the past decade was the release of @axi0mX’s hardware-based checkm8 bootrom exploit. This exploit can’t be patched by Apple in a software update, and it essentially guarantees the jailbreakability of several of Apple’s devices using the A5-A11 SoC for life.

While checkm8 is already being used in the checkra1n jailbreak for handsets ranging from the iPhone 5s to the iPhone X, it’s also true that the same exploit can be used to jailbreak compatible Apple TV units. The newest Apple TV, on the other hand, purportedly sports a hidden Lightning port that would necessitate a special adapter to utilize for such an exploit.

Trouble jailbreaking with checkra1n? Try this…

If you’re anything like me, then you’re ecstatic about the release of the checkra1n jailbreak. It’s an exciting development that utilizes @axi0mX’s checkm8 bootrom exploit to facilitate software liberation on handsets ranging from the iPhone 5s to the iPhone X. Moreover, it’s the first public jailbreak to support iOS 13.

But it’s difficult to ignore the elephant in the room here, and that’s the sheer number of public beta testers that have reported challenges getting into DFU mode and jailbreaking, citing common issues such as Error-20 and failure to boot jailbroken.

How to jailbreak with checkra1n

The checkra1n team officially released the checkm8 bootrom exploit-based checkra1n jailbreak tool this weekend as a public beta to the masses, and while we’d seriously recommend holding off until the tool comes out of beta, we’d totally understand if you’re a bit antsy to go hands-on with things right now.

In this tutorial, we’ll be showing you how to use the checkra1n jailbreak tool to liberate a supported iPhone, iPad, or iPod touch.

How to enter DFU mode on Apple Watch

Your Apple Watch is, in its own right, a tiny computer.

Just like any computer you've used, your wrist computer is susceptible to various software hiccups, some of which may prevent it from starting up or functioning properly. Should that happen, you'll need to perform a full restore of the watchOS operating system.

Unfortunately, Apple has made it difficult for users to restore Apple Watch so you'll need to schedule an appointment at your nearest Apple Store in case something goes awry with the watchOS software that couldn't be resolved by resetting to factory settings.

While Apple Watch lacks a Lightning port, it does sport a hidden six-pin diagnostic port for service technicians inside the groove of the bottom strap connector slot. Thankfully, MFC's unofficial iBus dongle lets you connect any Apple Watch via the standard Lightning cable to iTunes on your Mac or Windows PC, allowing you to perform a full restore.

The dongle is priced at $100 for the first-generation watches and $120 for Series 2 models.

We should point out a major caveat: Apple does not make the full watchOS restore files available publicly so you'll need to obtain the related firmware files from other sources before attempting to restore or update your Apple Watch with iBus.

How to enter Apple Watch DFU mode

In order to restore software on your Apple Watch from a firmware file on your computer, or downgrade to an older firmware, you'll need to put the device in DFU mode.

1) Remove the strap on the button side of your Apple Watch case.

2) Place the sewing needle in the port hole. Don’t press the needle to access that door like you would when opening the SIM card tray on your iPhone: instead, apply light downward pressure while pole-vaulting the needle to the side in order to pop the cover off the port.

Here's a video showing the process.

3) Now connect your iBUS dongle to the watch's diagnostics port.

4) Connect a Lightning cable to the other end of the dongle and the other end of the cable to your computer's USB port, then launch iTunes.

5) Turn on your Apple Watch and wait until it boots.

6) Press and hold both the Digital Crown and the Side button for ten seconds, then release the Side button while still holding the Digital Crown until iTunes greets you with a message confirming your Apple Watch is in DFU mode.

Not unlike putting your iPhone, iPad or iPod touch in DFU mode, you will be asked to select a watchOS firmware file (.IPSW) for restore.

The following video shows the full Apple Watch restore process with the iBUS dongle.

It's worth noting that performing any kind of software installations through the diagnostic port on your Apple Watch will void your warranty and potentially impact the water resistance of the device so proceed at your own risk.

How to place Apple TV in recovery mode

If your Apple TV won't start up properly, or you are a developer who wants to install a tvOS beta, you must first put your set-top box in recovery (DFU) mode. As is the case with iPhone, iPod touch and iPad devices, entering DFU mode makes a malfunctioning Apple TV discoverable in desktop iTunes so you can restore it to factory settings, downgrade to an earlier version of the software or side-load a beta firmware onto it.

The method to put an Apple TV into DFU mode differs from that for other iOS devices. In this post, you'll learn how to put an Apple TV into recovery mode so you can restore it to factory settings if it's acting up.

How to jailbreak iOS 5.1.1 on Pre-A5 devices using backup and restore

We've been stressing how many new features were packed into the new RedSn0w, and we weren't kidding. Another under the radar feature that's been added to the new RedSn0w is the ability to jailbreak iOS 5.1.1 untethered on Pre-A5 devices in A5 Non DFU style.

This is accomplished using the same method used for jailbreak tools like Absinthe, which utilizes backup and restore instead of the typical DFU ramdisk method. This is a great feature that speeds up the jailbreak process on Pre-A5 devices running iOS 5.1.1. Check inside as we give you a video demonstration and tutorial showing how it works.

How to downgrade iOS 6 to iOS 5.1.1 on A4 devices

Have an iPhone 4, iPod touch, or below running iOS 6, and would like to downgrade back to iOS 5.1.1? Doing so is easy is you have your SHSH blobs saved for iOS 5.1.1 and can follow the steps inside. Unlike the beta period of iOS 6, you must have your SHSH blobs for iOS 5.1.1 save for you device now, because Apple has stopped signing iOS 5.1.1.

To downgrade, you will need the latest public version of RedSn0w. We will use the SHSH Stitching feature to combine the appropriate IPSW file for 5.1.1 and your corresponding SHSH blob for the device you wish to downgrade. It may sound a bit confusing, but it's extremely easy if you follow along carefully.

Take a look inside for the full walkthrough and video how-to.

How to jailbreak an iPhone with a broken Home button

Although there have been methods in the past geared towards skirting around a broken Home button in order to jailbreak an iPhone, I don't remember any of them being as easy as this.

If your Home button is on the fritz, then chances are you have problems getting into DFU mode, which is a prerequisite to using most jailbreak software. Fortunately, the iPhone Dev Team has come up with a simple, yet ingenious method for easily pushing your device into DFU mode using their latest update to the RedSn0w jailbreak tool.

RedSn0w 0.9.14b2 allows you to create a firmware file that will push your device into DFU mode once a normal restore through iTunes is completed. Check out our full tutorial inside for the step-by-step video walkthrough...

How to Save iOS 5 SHSH Blobs and Create Custom Firmware to Downgrade iOS 5.x Using iFaith

As we told you yesterday, iFaith — the Windows based tool that allows you to manage SHSH blobs on all devices sans the iPhone 4S — has been updated with the ability to save iOS 5.x blobs, and create custom firmware that you can use to downgrade your iOS 5 device.

It works very similar to RedSn0w's stitching feature, except the big difference here is that it encompasses Apple's APTicket and features iOS 5 compatibility.

Up until now it was impossible to downgrade an iOS 5.x device to a previous version of iOS 5. That's no longer the case, as our video tutorial shows you inside...

Video Walkthrough of the New RedSn0w Jailbreak Tool

As we previously reported, RedSn0w received a massive update with its 0.9.9b1 iteration, released a few days ago.

This latest version of RedSn0w is a huge step in the right direction for the iPhone Dev Team, as it includes features like firmware fetching and caching, auto-detection from DFU mode, and SHSH blob management.

We're very excited about the future of RedSn0w, but admittedly, all of the new fangled features can be a bit confusing. For this reason, we've created a brief video walkthrough that touches on some of the new areas of RedSnow...

How to Put Your Apple TV in DFU Mode

Since we now know that it is possible to jailbreak the Apple TV (and install apps on it), one thing we need to learn sooner rather than later is to put the Apple TV in DFU mode. Putting the Apple TV in DFU mode is not complicated, assuming you know how to press a couple buttons together...

Step 1: Make sure your Apple TV is connected to your computer via a mini USB cable.

Step 2: On the remote, press and hold the Down and Menu button together for a few seconds. Your Apple TV will start blinking. You can now release.

Step 3: Now press and hold the Menu and Play button together for another few seconds.

Step 4: Done! Your Apple TV should now show up in iTunes, from where you'll be able to restore it.

Next step is getting a jailbreak for this Apple TV. I can't wait for that.
