For some specific models of the Oppo A5 (specifically those powered by Snapdragon processors), there have been "unbrick" tools leaked from Oppo service centers. These tools, often referred to as the MSM Download Tool, can flash the device in "EDL Mode" (Emergency Download Mode).
due to enhanced bootloader security (AVB 2.0 rollback protection).
Some versions of the MSM Tool require a login. Look for "patched" versions or "community" versions that bypass the login requirement.
