SamFirm AIO 3.1 (All-In-One) is a powerful Windows-based utility designed for advanced users, technicians, and enthusiasts working with Samsung Galaxy devices. Unlike official Samsung tools (Odin, Smart Switch), this tool focuses on bypassing factory resets, removing FRP (Factory Reset Protection), changing CSC (Country Specific Code), and extracting firmware information – all without requiring a Samsung account or a combination file in many cases.

Note: This tool is intended for legitimate device recovery and authorized servicing. Unauthorized bypassing of security features on devices you do not own may be illegal.

A common question from users: Will this tool harm my device or contain malware? Mahmoud Salah hinted on his Telegram that version 4

Safety Profile: SamFirm AIO 3.1 is generally safe if downloaded from the official source (Mahmoud Salah’s Telegram channel or GitHub repository). However, because it exploits security vulnerabilities to remove FRP, most antivirus software (Windows Defender, McAfee, Norton) will flag it as "HackTool" or "RiskWare." This is a false positive. The tool is not a virus; it simply behaves like one to legally bypass user locks on hardware you own.

Legal Note: You should only use this tool on devices you own. Bypassing FRP on a lost or stolen phone is illegal in most jurisdictions.
