: Flashing firmware via Odin usually wipes all user data. Always backup before proceeding.
Older versions of Odin (like 3.12.3) cannot extract or read LZ4 files, resulting in an immediate failure. Version 3.13.1 Patched combines the ability to read modern compressed firmware with the freedom of bypassed signature checks. Prerequisites Before Flashing
