Hardware variations among budget tablets mean that two devices using the same Allwinner A23 processor may utilize completely different touch screen controllers, Wi-Fi chips, or camera modules. These hardware-specific drivers are compiled directly into the firmware image. Flashing an image intended for a different tablet model will result in broken features, such as an unresponsive touch screen or a dead Wi-Fi connection.
