The LG G3 is the latest LG’s flagship smartphones this year, many say that this phone has great hardware specs and released to be able to compete with the Samsung Galaxy S5. Like its predecessor the LG G2, this phone will have an active android development, since it will also available with the four major carriers in the U.S., like Verizon (VS985), Sprint (LS990), AT&T (D850) and T-Mobile (D851) that will make it more popular, not only in the U.S. but also around the world. You might notice a lot of custom ROMs and mods that you can use to get the most out of this phone.
The LG G3 stock firmware usually consists of a stock Android OS, kernel, radio, bootloader, etc. which needed by our phones to be able to work normally. So, a stock firmware is often used to return an android device back to stock condition, and some even utilize it to recover from soft brick, then bring this phone back to life.
The standard stock firmware for LG devices are usually available in KDZ file or TOT format that comes with a massive file size (more than 1GB). Every stock firmwares are uniquely built, each LG G3 models have different firmware, so the firmware for a Korean version (F400K) can’t be used on the Verizon model (VS985), so do not even think to flash stock firmware that is not made specifically for your specific phone models.

Thanks to wolfgart from xda community for uploading the firmware. The firmware list above is not complete yet, but we will make an effort to constantly update the LG G3 stock firmware list with the latest one. Before flashing, we advise to verify the firmware’ version, and make sure it match with your current software version. Using the newer firmware (upgrading) sometimes works, however, downgrading (using an older) usually will not work and will only add new problems, unless someone have tried it and succeeded.
