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. Read More
Motorola has always offered an official bootloader unlock option for the Moto X devices, but not all variants have been eligible. Specifically, AT&T and Verizon have blocked the process. Now, that's starting to change with the addition of Verizon's 2014 Moto X to the list of unlockable devices. Read More
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. Read More
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. Read More
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.
The ASUS Zenfone 2 has proven a popular device in its first few weeks on the market. It's reasonably priced and has good specs. As David pointed out in our review, the software is its biggest issue, so you know there are tons of users anxious to mod the crap out of it. Good news on that front—there's now a bootloader unlock method, and it's not terribly messy.
New smartphones are rolling off the line pretty regularly, and that means the tools we use to work with them have to update, too. Last month, Sunshine v3.0 emerged with support for an extensive collection of HTC and Motorola handsets, and now an update to v3.1 is about to build on that list. With the latest release, Justin Case and Beaups have added support for almost every variant of the HTC One M9, except Verizon's. Expanded compatibility isn't the only new treat for users, Sunshine has also added the capability to automatically SIM unlock most of the GSM-based phones manufactured by HTC. Read More
If you're going to do any serious modding on your Android smartphone, your first step is going to be unlocking the bootloader. This is a simple procedure on Nexus devices and a few other handsets, but many of the top OEMs have added security measures to prevent regular users from mucking about with their stock software. For these devices, there's a tool called Sunshine by recognized developers Justin Case (jcase), beaups, and friends. Version 3.0 just came out, and it can unlock the bootloader and acquire S-Off with almost every modern Motorola and HTC smartphone on the market. Read More
Using an unlocked bootloader on your phone or tablet is not safe. Don't do it. Unless you want root permissions, or the ability to backup and restore your software via a custom recovery, or you want to use a ROM that didn't come with your machine. These things don't make an unlocked Android device any safer, but they are pretty good justifications for unlocking your bootloader. If you'd like to have all that unlocked cake and metaphorically eat it too, the BootUnlocker app is your friend. Today it works on the popular OnePlus One as well as the usual Nexus devices.

Fastboot oem unlock is a command many Nexus owners know by heart. The command, which unlocks a Nexus device's bootloader, takes a special consideration in Android 5.0 Lollipop, though. The command will fail unless a certain box is checked in the device's "Developer Options" menu. This is a minor change, but one that isn't immediately obvious to the user.
On my Nexus 6 review unit, the option was already checked after I opened Developer Options, but it appears that may not always be the case, as one tipster indicated the option on the Nexus 9 had to be checked manually.
As a quick reminder, the Developer Options menu is unlocked by tapping your device's build until the on-screen countdown completes. Read More
