Sometimes it happens that Alcatel OT-5010 mobile suddenly turns off and neither charges nor is detected by the computer. Such a situation is surprising for most users because there is no apparent problem. In fact, the mobile goes into brom mode where it only accepts a specific signed DA Auth File. Normal USB connection or recovery mode does not work at this time because the mobile’s secure boot protection is enabled. This is the moment where the DA file plays the role of an emergency key. This file bypasses the mobile’s bootrom through specific keys and provides a temporary flashing environment. With the help of the DA file, an expert flashing technician can not only get the mobile re-detected but can also revive the mobile by rewriting the corrupt preloader, boot image, and nvdata partitions. This is the stage where the mobile returns to its life, and all this is possible only through the DA Auth File..
When Alcatel OT-5010 mobile gets FRP lock after hard reset, and Google Account verification is not possible, then people usually start trying soft bypass apps or OTG methods. But when all these methods do not solve the problem, then there is a need to use advanced method. DA Auth File plays a central role here. This file allows SP Flash Tool or MRT Tool to clean the FRP partition by giving access to the internal system of the mobile. This is the point where the original security of the mobile is overridden, but in a way that does not harm the system. When the FRP partition is completely erased, then the mobile becomes like new, without any old account obstruction. This whole process is very delicate, and DA file is its main component, without which any advanced bypass is not possible.
