Some users think that the scatter file, firmware and driver are enough, but when they flash with SP Flash Tool, the phone is not detected at all. Especially in mobiles like Tecno POP 2 B1P, which are equipped with MediaTek security, if the DA file is not there, no tool can do anything. This file unlocks a kind of permission level that allows you to reach the roots of the mobile. If the Tecno POP 2 B1P mobile has become dead after flashing or you are only feeling a faint vibration, then it is possible that the boot partition has become corrupt. In such a case, the phone neither goes into recovery nor fastboot. This is the time when nothing is possible without the DA file. This file not only allows you to write to the boot partition but also makes the phone bootable again.
If you encounter "device not recognized" or USB disconnection while installing the firmware, then you definitely did not include the DA file. In mobiles like Tecno POP 2 B1P where the security level is high, flashing without the DA file is an incomplete and failed process. In Tecno POP 2 B1P phones, when NVData gets corrupted and as a result, network does not come or IMEI becomes null, then it does not work without the DA file. This file is the bridge that gives write access to the NV partitions in the secure zone so that the phone can catch the signal again.
