The Galaxy S5 is finally available for purchase on a global scale, and as tradition would dictate, firmware files for the international variant of the device are now coming up online. The firmware are currently available for the international Snapdragon-powered variant (model number SM-G900F) and for select regions, but that should be changing in the next few days as Samsung continues to publish firmware for various countries and carriers. As always, these firmware files are useful for those who modify their phone's software and would like an easy way to return to stock should anything go awry, and can be download from our firmware section, where you'll also find firmware for basically every Samsung smartphone and tablet.
Update: Firmware for the Exynos variant (SM-G900H) are now online as well, along with firmware for the U.S./Canadian variants (SM-G900W8). Find them in the firmware section.
