If you like to mod your Nexus devices but you're also a fan of tight security, you probably already know BootUnlocker. It's a simple app that allows rooted devices to lock and unlock the bootloader without wiping user data. The developer, segv11, is back with v1.5.1 of this handy little utility. The latest update adds support for the WiFi (flo) and LTE (deb) variants of the 2013 Nexus 7 and the ability to set the tamper flag on the Nexus 4 (mako) and Nexus 5 (hammerhead).
Did you know it's possible to unlock your Nexus 5 bootloader without wiping user data? If your device has already been rooted and relocked for optimal security, then unlocking is just a button tap away thanks to the latest update to BootUnlocker. Support for Google's latest flagship phone was just added with an update to version 1.4 of the app from XDA member segv11. Sadly, both generations of the Nexus 7 from ASUS remain unsupported.
It's pretty disheartening to get an awesome new phone only to realize the bootloader's locked down tight. That's means no custom recovery, no ROMs, no custom kernels, no... anything fun. Until, of course, some dedicated developers get ahold of the device in question and bend it to their will. That's exactly what Project FreeGee has done for both the Sprint and AT&T variants of the LG Optimus G.
The tool essentially unlocks the bootloader of both devices, allowing a custom recovery - and eventually, custom ROMs - to be flashed.
