Chicos, acá la solución al DEAD BOOT del LS775 cuando pasamos un mal firmware y se apaga o simplemente está en puerto Qualcomm, después de tanto dar... Acá les dejo
1, Soldar la EMMC JTAG con los pines que acá dejo abajo
Debes estar registrado para ver imágenes adjuntar
En el soporte de Medusa Pro, también pueden verlos, hecho eso, recuerden la conexión no puede pasar de 4 cm de largo o va a fallar....
Simplemente ponemos la JTAG y va a conectar...
Usamos la opción Smart Repair... y luego de eso va directo al modo Download... Ahí flashear el KDZ y listo...
Importante... Recuerden cobrar RECONTRA bien, es una chamba bien complicada... El soporte de Medusa tiene casi todo el soporte, excepto por el firmware...
Pero creo que acá en está publicado...
