    Frequently Asked Questions

    SMR Jun-2026 fixes 41 vulnerabilities, 5 of them critical. Android Security Bulletin: 32, Samsung Semiconductor: 1, Samsung-specific issues (SVE): 8.

    No. A newer build for SM-A566B is available: A566BXXUEDZJ1. Install it instead of A566BXXSBCZF5 unless you need this exact version. The previous build was A566BXXSACZE2.

    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 Samsung Galaxy A56 5G must be on bootloader binary B (11) or lower.

    This build uses bootloader binary B (11). It can be flashed on a Samsung Galaxy A56 5G running binary B (11) 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.
