When INFINIX ZERO 5 X603B mobile does not show on the computer even when connected to USB and no USB sound comes, people think that the phone is completely dead. But this is often not the case. In fact, the phone blocks USB communication when secure boot fails. DA file is a specific program that removes this block and makes the phone readable. Through it, not only flashing is possible, but we can also rewrite the boot partition so that the mobile comes back to life. Users who are victims of FRP lock in their mobile and do not find any fast boot or recovery method useful, should resort to DA file. Especially in the INFINIX ZERO 5 X603B model, this file is the "master key" that allows opening every locked section. It not only helps in removing FRP but also enables options like backup restore, userdata format, and partition repair. Users who use advanced tools know very well that no successful operation is possible without the presence of DA file.
When we flash MediaTek mobiles, sometimes we get the error "status sec auth file needed". This is a very common problem when we are handling phones with new security like INFINIX ZERO 5 X603B. At this time, the DA file becomes a component that provides proper authentication to the SP Flash Tool so that it can access the secure partitions. Without this file, neither your flashing will be complete, nor will the mobile boot, but more errors may occur. It has become very common for errors like IMEI gone or null IMEI to appear in INFINIX ZERO 5 X603B mobiles, especially when we manually install new firmware. In such a case, just installing the software is not enough, but with the help of the DA file, we can restore the nvram. The DA file gives read/write access to the mobile in secure mode, through which we can restore the IMEI again and make the network active.
