AUF5 is available for US unlocked S21U

Firmware G998U1UEU4AUF5 is out now for unlocked S1 Ultras in the US (no new security patch, still Jun 1). It’s downloadable via Frija (CSC: XAA) if not yet available OTA from your carrier. The bootloader-number increment (from 3 to 4) implies that once you upgrade to AUF5, you no longer have the option to downgrade to an earlier firmware version.
