The Tecno IN5 (also known as the Tecno Camon i) is a MediaTek-powered smartphone released around early 2018. Like many modern MediaTek devices, it utilizes a "Secure Boot" mechanism that prevents unauthorized flashing or software modifications. To bypass this security when using service tools like SP Flash Tool, you often require a specific authentication (auth) file or a modern bypass utility. Understanding the Tecno IN5 Auth File
