Hello
I have happened something very strange. It turns out that after updating by ota of the global s
Stable 8.1.0 to the stable global 8.2.3, when I went to connect it to the pc for root the pc did not detect that it would connect anything.
The mobile if I connect it off to the pc or to a power outlet the LED blinks red and does not charge.
If I connect it on the mobile charge at the rate of 1% every 3 hours. Android boots, even lets me update per ota according to roms, I've reinstalled rom 8.2.3 from upgrade, I've gone back to factory, I installed a weekly rom, I've tried with deep flash cable.
Now I am in version 8.7.5.19 and I can not find a way to do root without pc that works to install twrp and to be able to install after wipes.
I have tried adb over wifi but without root it is impossible.
any ideas?
The mobile is a xiaomi redmi note 3 pro snapdragon (kenzo)

Do you connect to the pc in fastboot mode?, what does fastboot devices say?

gracias por responder.
Es indiferente cómo lo conecto.
Nunca detecta nada.
administrador de dispositivos no detecta nada, como si nunca se había conectado en absoluto.
Forgive my English, use the translator.

Are you sure about the cable, did you try on all usb ports, eventually on another pc?

Si he limpiado el puerto del teléfono.
He tratado de 5 o 6 cables.
Todos los puertos USB de la PC.
He probado varios sistemas operativos, Windows y Linux.
He tratado entre 2 pcs.
Y siempre el mismo resultado

Try to clean your phone usb port to see if it improves.
