Improper use of FRP tools—especially those manipulating partitions (EDL mode)—can result in: e-frp-easy-firmware

Standard FRP locks a device to the last synchronized Google Account after an unauthorized factory reset. For individual users, this is an effective safety net; however, for organizations managing thousands of devices, it often results in "bricks"—devices that cannot be repurposed because a departed employee's credentials are still tied to the hardware.
