Infinix Smart 3 and 3 Plus (X5516 / X627) launched in April 2019 with Mediatek processor and runs out of the box with Android 9.0 Pie. Now, if you’re using the Infinix Smart 3 or Smart 3 Plus device and facing issues like authentication or buffer error, you will need to fix it via the SP Flash Tool or Miracle Box or CM2 box. But if you don’t fix it, you will encounter a secure boot error. In order to flash those devices, you will require a Secure Boot DA file. Here you can download and install for both the Infinix Smart 3 and 3 Plus MTK Secure Boot DA file.
