Fero Pace 2 If a mobile is accidentally affected by water damage or high voltage, then in most cases it becomes dead. But in some cases, the motherboard remains intact but the software gets corrupted. In such cases, the DA Auth File provides a diagnostic gateway. Software like SP Flash Tool or Miracle Box sends a ping to the BootROM of the mobile through the DA file. If the mobile responds, then it is hoped that flashing is possible. Then with the help of the DA file, the scatter file is loaded and a step-by-step system recovery is done. Although this entire process takes time, it is impossible without the DA file..
Some users root their Fero Pace 2 mobile to improve its performance and install custom ROMs. But if during this time the vbmeta partition gets corrupted then the mobile does not boot and dm-verity error comes. This error can be resolved only through DA Auth File because vbmeta is a secure partition which accepts only signed flashing. With the help of DA file, this partition can be bypassed and new vbmeta can be written, and after that the mobile starts booting again. This is the advanced stage where only the use of professional tools and DA file becomes a guarantee of success.
