How to download SM-X926B firmware

We do not host firmware. Download it directly from Samsung's servers with a free open-source tool, for example samloader:

samloader download -m SM-X926B -r EUX

Replace EUX with your region code. Step-by-step instructions, including a graphical alternative: How to download Samsung firmware.

Changelog and security patch level

Samsung publishes the release notes for each update, including the security patch level, on its own site. They are listed per region – for example SM-X926B / EUX release notes on doc.samsungmobile.com. Each region page here links to the notes for that code. We don't show the patch level ourselves because Samsung's update servers don't report it (why).
