Critical vulnerability Pork Explosion revealed by jcase, cripples security on some phones

Security has been a hot topic on Android for many years, particularly as smartphones take on increasingly significant roles both at home and at work. A single device acts as your main form of communication, contains personal photos and confidential documents, and may even have access to your finances. Google and other companies have made significant investments in time and money to ensure these devices are very hard to break into. However, a vulnerability was recently discovered in some phones that compromises important security measures and opens devices up to various types of attacks. The worst part is that it was created intentionally by a manufacturing partner contracted to build the phones, and the OEMs that designed the phone had no idea.

Confirmed: the Verizon Pixel's bootloader will not be unlockable

Thought that Verizon was warming up to the idea of less carrier intrusion because there aren't any obnoxious Verizon logos on the device? Well, you thought wrong. Just minutes before the event, @evleaks tweeted that the Verizon Pixels' bootloaders would not be able to be unlocked; that information has now been affirmed by a Google representative at the San Francisco event.

Motorola confirms the bootloader on the Amazon Prime Exclusive Moto G4 can't be unlocked

Motorola's relationship with unlockable bootloaders, and thus with the ROM-flashing aftermarket community, can be summed up as "complicated." While its default approach is to offer a consumer-friendly bootloader unlock on most of its phones, it nonetheless bows to the whims of its carrier masters (Verizon and AT&T) whenever they insist that said feature be disabled, and they don't offer those handy full-price Developer Editions anymore, either. Add Amazon to the list, because the retailer's customized, super-cheap edition of the fourth-generation Moto G can't be bootloader unlocked.

[No Cables, No Problem] Fastboot Gains Networking Capabilities, Wireless Flashing Isn't Far Off

If I were to say that I'm going to flash a new system image to your Nexus phone without attaching a USB cable, you might think I'm a little crazy. Well, I could be a little crazy, but that thing about the cable is definitely coming true in the very near future. Google has added networking support to the fastboot tool. When paired with a phone with a supported bootloader, it will be possible to perform all of the usual fastboot commands wirelessly.

In a recent commit to AOSP, support for the TCP protocol was added to fastboot. The Transmission Control Protocol (TCP) is one of the basic building blocks of communication on the Internet, used for reliable transmission of data from one point to another.

Xiaomi Customers Are Frustrated By The Manufacturer's Convoluted (And Possibly Biased) Bootloader Unlock Program

Any grizzled veteran of the aftermarket Android community (well, grizzled, in the sense that said community has been around for less than a decade) knows that users complaining about bootloaders is nothing new. Locked phone bootloaders with no user-accessible unlock option have become less of a contentious issue of late, now that customers on Neolithic carriers like AT&T and Verizon have more hardware options. But frustration is brewing in the growing and dedicated fanbase of Chinese manufacturer Xiaomi.

The XDA-Developers blog reports that Xiaomi has added locked bootloaders to several of its phones, including the Redmi Note Pro, Mi 4c, and Mi Note Pro, some of which are getting new bootloaders installed with the latest firmware.

PSA: Unlocking The Nexus 6P Bootloader Requires The New 'Flashing' Command, Likely To Become Common For Many Devices In The Future

By now most orders for the Nexus 6P have been delivered, or at least getting close. If you haven't tried unlocking the bootloader yet, it might come as a surprise that the 'fastboot oem unlock' command no longer works. Attempting to use it with the Nexus 6P fails with a message that it is an unknown instruction. Don't worry, this doesn't have anything to do with drivers, and it isn't a fluke. Google had Huawei replace the oem command in the Nexus 6P bootloader with the new flashing command. Here's what it will look like:

fastboot flashing unlock

fastboot flashing lock

fastboot flashing unlock_critical

fastboot flashing lock_critical

fastboot flashing get_unlock_ability

There are two levels of unlocking: normal and critical.

Why Does My Android Phone Have eFuses And Why Should I Care About Them?

This is a guest post by Ricardo "arcee" Cerqueira who takes things apart for sport, on a quest to understand how they work. He currently works on Android devices at Cyanogen.

As people started receiving their Nexus 6Ps, some began freaking out over a new message that comes up on the screen when booting into fastboot mode: “QFUSE: ENABLED,” with wild speculative theories coming up regarding what it does and doesn’t do, what kind of limitations it’s imposing, and wondering if and how it can be “disabled.” So... what’s this qFuse thing, anyway?

Think of an eFuse as the mind’s eye representation of a bit that only flips one way, or something that can only be done once on a piece of writeable flash.

Motorola Says That Unlocking The Bootloader On The Moto X Pure Edition Will Void Your Warranty

Looking to apply some root modifications or custom ROMs to that sweet Moto X Pure Edition (AKA the Moto X Style outside the US) you just got from Moto Maker? You might want to think twice. According to an employee post on the official Motorola support forum, the Moto X Pure Edition is not considered a developer device (like the Developer Edition versions of previous Moto X and DROID phones), so fiddling around with aftermarket software means you're on your own when it comes to support.

The new (2015) Moto X Pure is not a developer edition, so unlocking the bootloader does void the warranty.
