The Vivo Y81 was launched back in June 2018 that runs on Android 8.1 Oreo with Funtouch OS 4 out-of-the-box. As the handset is equipped with a MediaTek chipset, here we’ve shared the guide on How to install Vivo Y81 Secure Boot DA auth file and Bypass FRP lock with all the requirements and links. If in case, your Vivo Y81 is facing authentication or buffer error, you will require SP Flash Tool or Miracle Box to fix it. Otherwise, you will get a secure boot error. Therefore, you will need a Secure Boot DA File.

The Secure Boot doesn’t allow developers to access the internal storage of the handset, that’s why we need to use Secure Boot DA Loader files. By using this file, the MediaTek device users can flash firmware or unlock the FRP as well. Either you can use SP Flash Tool or Miracle Box or NCK Box to install the secure boot DA file. Now, let’s take a quick look at the device overview below.
