It is the same firmware configured per region and carrier (CSC). Find your country below, verify the file and download for free. Compared with the previous build G991WVLU1AUAG: bootloader binary raised from 1 to 2, so after installing it there is no way back to older builds; security patch 2021-03-01 instead of 2021-02-01. A newer build for SM-G991W is available: G991WVLSJHZAA.

    Frequently Asked Questions

    G991WVLU2AUB5 is Android 11 firmware for Samsung Galaxy S21 5G, released for Canada (BMC, BWA, CHR, ESK, FMC, GLW, KDO, PCM, PMB, RWC, SOL, TLS, VMC, VTR, XAC). It includes the 2021-03-01 security patch. Samsung built it on 2021-03-09.

    No. A newer build for SM-G991W is available: G991WVLSJHZAA. Install it instead of G991WVLU2AUB5 unless you need this exact version. The previous build was G991WVLU1AUAG.

    Download the package for your region (CSC) and unzip it. In Odin, load each file into the slot with the same name: BL, AP, CP (if the package has one) and CSC, or HOME_CSC to keep your data. Odin checks the built-in checksum of every .tar.md5 file before flashing. The download is 6.469 GiB; keep about twice that free on the computer to unzip it. The Samsung Galaxy S21 5G must be on bootloader binary 2 or lower.

    This build uses bootloader binary 2. It can be flashed on a Samsung Galaxy S21 5G running binary 2 or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". 1 other build of this model uses the same binary, so you can switch between them in both directions.
