When using Odin3 (Samsung's proprietary flashing tool), a missing or corrupted modem driver can cause the secure check fail : modem or sw rev check fail error. Odin requires the Windows host to communicate directly with the modem partition via USB.
This document summarizes the Samsung Modem Support Stack (MSS) device driver for Android — version 3 — covering architecture, components, driver responsibilities, integration points, build and deployment notes, common issues, and troubleshooting tips. Assumptions: target devices use Samsung modem hardware integrated via SoC or discrete modem; Android kernel is Linux 5.x or later; driver interacts with Android telephony framework via RIL/HAL.
For developers and kernel engineers, understanding the underlying architecture is vital.
Historically, Samsung devices used simple modem interfaces (like ACM or SIPC). With the introduction of the Exynos 2100 (Galaxy S21 series) and Exynos 2200 (S22 series), Samsung moved to a more secure, partitioned modem system called MSS (Modem SubSystem) . samsung android modem device driver mss ver3 link
If you clarify what specific “link” you meant (e.g., DIAG over USB, PCIe link training, IPC channel mapping, or modem bootloader download link), I can provide an even more focused, step-by-step guide with code examples.
