LG’s latest beast with powers like never before, the LG G3 features a 5.5 inches True HD-IPS display, Qualcomm Snapdragon 801 Quad-core 2.5 GHz Krait 400 processor, Adreno 330 Graphics unit, 13 MP high-res Camera with 3 GB RAM for better performance and smooth user-interface. The device was released during May 2014, proving itself to be a strong contender against all other high-end flagships including Sony Xperia Z3, Oppo Find 7, Samsung Galaxy S5 and the HTC One M8.

One of the top-rated and reliable Custom Recovery for Android, i.e TWRP Recovery, has been released for all the variants of the LG G3 by the famous Codefire team. All set and ready to be installed and hence we’re here to guide you through the process of installing TWRP Recovery and to Unlock LG G3 using Bump!. Now, you must be worrying about “bump!“? Bump! is another very reliable program to allow flash any boot images to your LG G3 with a locked bootloader. So, now if anything that has to be flashed to the G3 needs to be bump’d. Following from now on, most of the ROMs you download will be pre-bump’d to ease the process.

We greet the team Codefire for this impressive work and all the LG G3 users, for now, the flashing process will be made a hell lot easier.
