If your Tecno Spark Go KE5 mobile suddenly gets the error “status_sec_auth_file_needed” while flashing, then it is a clear sign that the mobile has blocked the secure boot protocol. At such a time, the SP Flash Tool becomes silent and the mobile only shows charging. This all happens because the mobile’s bootloader has detected unauthorized access. When you try to flash again by loading the DA Auth File, it temporarily suspends the mobile’s security system and allows the flashing tool to rewrite encrypted partitions like lk, tee, vbmeta. If you have the DA file that is specifically made for the Tecno Spark Go KE5 model, then this process is completed without any brick. With this method, the original state of the mobile can be restored and the user gets full access again..
Some users want to install a custom ROM to get a new UI, faster speed, and special features on their Tecno Spark Go KE5 mobile. But when they try to install TWRP or any custom recovery, the boot verification fails. This happens because the mobile’s secure boot mechanism only accepts signed images. DA Auth File is a game changer in this scenario. When you load this file into the flashing tool, it temporarily unlocks the bootloader and enables the installation of custom recovery. After that, you can easily flash Magisk or a custom kernel. This whole process is a godsend for advanced users, but it is essential to have the correct DA file, otherwise the mobile may get bricked.
