Many times, the mobile seems to be dead. When problems like boot loop, logo stuck or FRP lock arise in phones like Tecno POP 3 BB2, users get panicked. They think that maybe only the company can fix the phone now. However, experts know that behind such problems there is often hidden security that does not give entry to normal tools. DA file temporarily bypasses this security and gives full access to SP Flash Tool. This is the file that brings the dead mobile back to life.
Whenever you connect your Tecno POP 3 BB2 mobile to USB during flashing and you keep getting BROM Error, STATUS_SEC_AUTH_FILE_NEEDED or any authentication error then understand that your phone is in Secure Boot. Normal files and scatter file do not solve this problem. DA file is the only way to unlock this security level and give full access to the mobile so that the software can be reinstalled.
