Today’s modern Condor P8 Pro mobile phones have high-level security protocols, especially in MTK based devices. If you try to perform unauthorized rooting or firmware modification on such a phone, it automatically locks the bootloader and blocks any kind of flashing attempt. In such a situation, only the DA Auth File is the only source that provides SP Flash Tool with access to the basic bootrom of the mobile. This file technically disables secure boot temporarily through a signed handshake process, which makes it possible to take the mobile into flash mode. This file is so important that without it, neither the mobile can be unbricked, nor can complex issues like FRP or IMEI be resolved..
Sometimes a new system update comes from the company on Condor P8 Pro mobile which inexperienced users install by themselves, but if an error occurs during the update, the mobile shuts down with the message "encryption unsuccessful". Recovery mode, fastboot mode, nothing works. In such a situation, DA Auth File is your only hope. DA file is provided to SP Flash Tool with specific cryptographic signatures with the help of which a new ROM can be inserted by overriding the corrupted encryption. After this process, the mobile comes back to life with a new system in a completely clean state.
