BootUnlocker for Nexus Devices is a free Android app which helps you unlock the bootloader from within the Andriod operating environment without going in fastboot mode in Nexus 4, Nexus 10 and Galaxy Nexus. This way, not only your data remains intact but also the device remains safe from any malicious vulnerabilities since bootloader itself is not unlocked, only a few bits are changed in the /param partition to allow the modifications that you need.

How do bootloaders normally work? On Android, bootloaders are humorous tricky things. On one hand, you cannot resist but unlock them to open up a world full of modifications and customizations enjoying super user access, and on the other you are indulging in the above luxuries all the while risking your own security by making your device potentially vulnerable to any malicious attacks.

Add to that the recent vulnerabilities caused by manufacturers’ negligence like Samsung Exynos memory exploit and you are all set for getting attacked by the smart wicked world outside. Once open, it is hard to have that same old fun on Play Store, getting worried about the authenticity of the bulk of apps that are being added in the store on daily basis. You can never be sure if it’s what it claims to be or the app is disguised to steal your personal information out of your device.

On Nexus devices, unlocking is even easier using Fastboot, more like a bite of brownie making it an ideal approach for manufacturers bootloaders’ access. You go to the Fastboot mode, enter “fastboot oem unlock” and tada! But on the darker side it also involves wiping your data off acting as a pseudo-security measure. Along with that, once bootloader is unlocked, the entire data and partitions get cleaned up which means you have to work on your device from scratch to put it in order. There is definitely a technique to get that data back after unlocking bootloader on Galaxy Nexus devices, but many users fail to lock the bootloader back to keep the security intact. This negligence results in opening up the device to again malicious attacks.

That is where BootUnlocker for Nexus Devices will help you by not only saving your data from wiping out but also keeping your Nexus devices off the external attacks. This Android application requires a rooted Nexus device to let you unlock and relock the bootloader as many times as you want to. BootUnlocker only works on /param and doesn’t open the miscellaneous partition hence keeping certain measures of security in control.

Note: BootUnlocker does not work on Nexus 7 devices.
