Cómo escribir en la memoria flash del dispositivo con Android Flash Tool
Android Flash Tool te permite escribir en la memoria flash del dispositivo Pixel compatible una imagen del sistema de manera segura. Android Flash Tool funciona con cualquier navegador web que admita WebUSB, como Chrome o Edge 79 y versiones posteriores.
Android Flash Tool te guía paso a paso durante el proceso de escritura en la memoria flash del dispositivo. No necesitas tener herramientas instaladas, pero deberás desbloquear el dispositivo y habilitar la depuración por USB desde las Opciones para desarrolladores. Si quieres ver las instrucciones completas, consulta la documentación de Android Flash Tool.
Conecta tu dispositivo por USB, ve a Android Flash Tool con el siguiente vínculo y sigue las instrucciones en pantalla: https://flash.android.com/preview/baklava-dp1.
Cómo realizar la instalación manual en tu dispositivo
También puedes descargar la imagen del sistema más reciente e instalarla en tu dispositivo de forma manual. Consulta la siguiente tabla para descargar la imagen del sistema correspondiente a tu dispositivo de prueba. La escritura manual en la memoria flash de un dispositivo es útil si necesitas un control preciso del entorno de pruebas o si debes reinstalar el sistema con frecuencia, como cuando realizas pruebas automatizadas.
Después de crear una copia de seguridad de los datos del dispositivo y descargar la imagen del sistema que coincida, puedes escribir la imagen en la memoria flash del dispositivo.
Puedes volver a la compilación pública más reciente en cualquier momento.
