G920AZTUS7DRA1 – Galaxy S6 firmware

Build G920AZTUS7DRA1 is a security update for the Galaxy S6 (SM-G920AZ) on Android 7. It first appeared on Samsung's servers on Feb 14, 2018 (method) and has reached 1 region so far. It raises the bootloader bit from 6 to 7: once installed, the device no longer accepts firmware with bit 6 or lower, so a downgrade to G920AZTUU6DQL2 is blocked. Samsung has pulled this build: the file is no longer served (what this means).
