Hola!
Estoy intentando hacerlo y me da error, por que puede ser? Copio lo que salen en android flasher:
C:\Users\Carlos\Desktop\AndroidFlasher1.8.0>@
echo off
cd data\
taskkill /F /IM adb.exe
Correcto: se terminó el proceso "adb.exe" con PID 4600.
taskkill /F /IM fastboot.exe
adb.exe reboot bootloader
* daemon not running. starting it now on port 5037 *
