    How to flash G996BXXS9FXAI

    • HOME_CSC: Use HOME_CSC to update the same model and region while keeping your data. Back up anyway: a failed update can still require a reset.

    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 7.677 GiB; keep about twice that free on the computer to unzip it. The Samsung Galaxy S21+ 5G must be on bootloader binary 9 or lower.
