Sometimes the mobile restarts continuously after flashing, and the system does not recover. This shows that the flashing is not complete, and it is possible that the DA file has not been added. This file can not only turn on your mobile but also completely restore the system. If the Tecno Spark 4 Air KC6 mobile fails immediately during flashing and gives “ERROR STATUS_BROM_CMD_SEND_DA_FAIL”, then this is a clear sign of the absence of the DA file. Without this file, the connection between the mobile and the system cannot be completed. The DA file may seem complicated to a common user, but in fact it is a security bypass that temporarily unlocks the MediaTek system and prepares the mobile for full flashing, especially in models like Tecno Spark 4 Air KC6.
When a user flashes his mobile with SP Flash Tool for the first time and the mobile is not detected, he immediately thinks that the mobile is damaged. However, if the DA file is added, the Tecno Spark 4 Air KC6 mobile is immediately connected to the tool and the complete system repair can be done. When there is a software problem in today's modern mobiles like Tecno Spark 4 Air KC6, most people get worried about what to do now. If the phone is stuck on the logo, not turning on at all or giving an error during flashing, then understand that the problem is not normal but security related. In such a situation, the DA file is a blessing, which allows the SP Flash Tool to access the internal system of the mobile and install the firmware correctly. If you want to revive a phone like Tecno Spark 4 Air KC6 without any problems, then do not ignore the DA file.
