: Windows 7 32-bit and Windows XP 32-bit do not enforce driver signature verification by default. The “disable driver signature enforcement” procedure described online is primarily for 64-bit versions of Windows (particularly Windows 7 64-bit and Windows Vista 64-bit).
Always scan driver files from unknown sources with antivirus software. Many "free driver download" sites bundle malware. Prefer drivers from official flashing box support forums or trusted repositories like GSM-Hosting or MegaUnlock .
Since Windows 7 32-bit is the most stable platform for this driver, we will focus on that. Windows 10 32-bit works with driver signature enforcement disabled, but Windows 7 is recommended.
