Always download Octoplus software exclusively from official sources. Unofficial portable versions may contain malware, keyloggers, or altered code that could damage phones, steal personal data, or compromise your PC. The Octoplus development team has specifically warned that "not actual Software version may not support the latest device security type, and 'Read Codes' or 'Unlock' operation may be not successful" , and this risk is multiplied many times over when using untrusted third‑party modifications.
