If unlocking a bootloader were as easy as inserting a key and turning, there would be a many fewer people angry at Motorola. Unfortunately for new users, it isn’t and often involves manually entering commands. While this isn’t difficult, many new users can certainly appreciate a step-by-step guide to walk them through the process—especially when the guide explains each step and provides screen shots.
Thanks to XDA Senior Member fma965, Sony Xperia Play users now have such a bootloader unlock guide to walk them through the process. Additionally, the guide has a few additional tidbits of information. For instance, some Xperia Play devices can have their bootloaders unlocked manually and some can’t. This guide will immediately help identify which is which. As if that weren’t enough, the guide thread also contains all of the required ADB drivers and fastboot files so users do not need to install the Android SDK in order to make it work.
