For some reason LG decided to ship the Optimus G with a locked bootloader. We don’t get this since this is pretty much a non-Google branded version of the Nexus 4, which is a open as a device can be.
Anyway, Android community doesn’t like this and few folks who know what they’re doing decided to do something about it. So the bootloader unlock tool was born, allowing Optimus G owners to hack their way to the system and customize it the way they always wanted (but couldn’t do so).
XDA-Developer member “thecubed” unveiled Project FreeGee, which at the moment works with Korean and American versions of the device, only. However, the list of country-specific models will keep growing and the next in line is Canadian Optimus G.
After unlocking the phone, you can install any ROM you want, including the “basic one” which ships with the Nexus 4.
This isn’t something everyone should be doing since messing with custom ROMs can void your warranty. If that’s not a problem, you are free to join the conversation at XDA-Developer forums. Let us know how that works for you…
