Hey everyone, I'm hitting a wall while trying to [flash firmware / bypass FRP / reset PIN] on my [Insert Phone Model, e.g., Infinix Smart 8] . I’m using [Insert Tool Name, e.g., SPD Flash Tool / CM2 / Unlock Tool] , and everything seems fine until it reaches the FDL2 stage. Error message: Sending FDL2...
