There is also a problem in Hisense C30 Lite mobile where the mobile boots only on charging and pressing the power button does not do anything. This problem often comes up in the case of bootloader corruption or failure of custom recovery flashing. At a time when all the button combinations have failed, DA Auth File is the only source left through which SP Flash Tool can write a new boot image or recovery directly to the boot partition. This file bypasses the core level protection of the mobile and gives you the permission that can recover the boot section. This process of bringing life back to the mobile is very sensitive and can only be successfully done by an experienced flasher with the help of DA file..
Some mobile phones like the new models of Hisense C30 Lite come with advanced versions of secure boot in which the brom handshake is also encrypted. If you try to flash such mobiles without the correct DA Auth File, then an error code like 0xC0030004 immediately comes up, which indicates unauthorized access. It seems impossible to bypass these error codes, but the presence of the DA file makes this impossible possible. This file contains the authorization algorithm of the specific vendor, which temporarily unlocks the mobile and gives access to every section of it. Whether you want to update the system, replace a corrupt partition or unlock FRP, all this remains a dream without the DA Auth File.
