[Update: OnePlus promises a fix] OnePlus 6 bootloader vulnerability could allow anyone with physical access full control of your phone

One of the most elementary aspects of phone security is the idea of a locked bootloader, which is supposed to prevent a handset from flashing or booting arbitrary code, ostensibly keeping the software on the device secure. It's super basic—or, at least, it's supposed to be. Turns out, the OnePlus 6 will allow you to boot any arbitrary or modified image you choose, even on a locked bootloader.

[Update: No longer possible] Verizon Pixel 2 bootloader can be unlocked via a simple fastboot command

The biggest disadvantage to picking up the smaller Pixel 2 on Verizon's network is the locked bootloader. Big Red dictates that the phones it sells have to be locked down tight. That's a problem if you're into ROMs or if you'd like to root without an exploit. However, the folks over in the XDA forums have discovered a trivially simple way of unlocking the bootloader which is every bit as easy as the typical method for non-carrier locked Pixel 2 phones.

Google makes ADB, fastboot, and other platform tools available without full SDK or Android Studio download

As an Android nerd, there are times you probably need ADB or fastboot to mess around with your phone. Maybe you're flashing an OTA or unlocking the bootloader. You used to need to grab a giant package of other junk from Google to get them, but no more! Google has started hosting platform tools downloads without the other stuff that are a mere 3.5MB.

Android 7.1 feature spotlight: A closer look at seamless updates, partition changes, and new fastboot commands

During the I/O 2016 Keynote presentation, and again at the October 4th Pixel announcement, Google made brief references to newly added support for seamless updates in Nougat. To make this work, many changes had to be made to the structure of Android and its assorted system partitions. As a result, there have also been some changes to the fastboot utility many of us use when new factory images become available. This post covers a few of the technical details and also demonstrates some of the ways to use the new features.

How it works

Seamless updates are accomplished by creating a second set of logical partitions in device storage.

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.

FlashFire v0.32 Can Create Fastboot-Flashable Backups And Adds An Option To Preserve Recovery Through OTAs

If you're into rooting these days, there's a good chance you've at least tried out FlashFire by well-known SuperSU developer Chainfire. It's one of the friendliest tools to use for flashing firmware images and mods, and it can even install official OTAs while keeping root intact. Today, Chainfire is releasing a new version of FlashFire with a pair of new features that will make it even more powerful: it can now create fastboot-flashable backups and there's a new option to preserve the existing recovery after installing OTAs and ZIPs.

Fastboot-Flashable Backups

FlashFire has long had the ability to create backups, but they could only be restored through a custom recovery or from FlashFire itself.

[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.

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.

Users Report The Bootloader On The Dell Venue 8 7840 Can Now Be Unlocked With 'Fastboot OEM Unlock,' Nexus-Style

Earlier this week the super-skinny Dell Venue 8 7840 was given its Android 5.1 update. It looks like the firmware developers left in a goodie for power users: the new "OEM Unlocking" option in the Developer Options menu, first noticed on the latest round of Nexus devices when Lollipop 5.1 was going out earlier this year. According to an Android Police tipster and multiple posts on the XDA-Developers forum, this allows end users to easily unlock the bootloader of the tablet, something that wasn't a simple process before.

To unlock the bootloader, you just need to go through the familiar steps that are shared across most Nexus and "developer" devices: install Fastboot on a PC, make sure you've got the right drivers, connect the device, reboot into fastboot mode, and execute the command "fastboot OEM unlock." The only difference is the addition of the prerequisite manual switch in the Developer Options menu when Android is booted.
