USB problem P40 5g - Huawei P40 Questions & Answers

Good afternoon,
This morning I have downgraded my P40 5g to Emui 10, installed google services and updated to Emui 11 again, after this process I have realized that neither the quick charge nor the data transfer works for me , nor does it recognize the connection of an OTG, I have tried several cables and chargers.
Anyone else has happened? It has a solution?
I am afraid to do a Factory Reset because if after this the USB data transfer does not work I would lose all google services and the possibility of doing another downgrade again.
Sorry for translation, my English is very bad.

Buenas tardes,
Esta mañana he downgradeado mi P40 5g a Emui 10, he instalado los servicios de google y he vuelto a actualizar a Emui 11, despues de todo este proceso me he dado cuenta de que no me funciona ni la carga rapida, ni la transferencia de datos, ni me reconoce la conexion de un OTG, he probado con varios cables y cargadores.
¿A alguien mas le ha pasado? ¿Tiene solución?
Me da miedo hacer un Factory Reset porque si despues de esto no funciona la transferencia de datos USB perderia todos los servicios de google y la posibilidad de hacer de nuevo otro downgrade.

Hey Mate! Im having the same issue... did you find a solution for this?

Nexus 5 RIP

Hola, antes que nada, soy nuevo en el foro, soy de España y mi ingles no es muy bueno, utilizo el traductor de Google, lo siento si este tema no va aquí, pero es que ya estoy desesperado. Mi Nexus 5 no se enciende, se apagó de repente, y al pensar que sería que se habia agotado la bateria, lo puse a cargar, y en vez de salir el icono de la bateria, salia el logo de Google unos 3 segundos y se apagaba, y asi sucesivamente, entraba en un bucle. No me deja entrar en modo recovery ni se enciende ni nada. He leido por ahi, que es problema de un boton interno. Espero que me ayudeis.
PD/ Lleve el movil a una tienda no oficial para ver si me lo podian arreglar y no me ayudaron, asi que perdi la garantia de Google. Ojala me ayudeis. Y si este no es el sitio de este tema, o ya hay una solucion espero que me ayudeis, ya que como he dicho no entiendo mucho el ingles. Os dejo los textos en español y en ingles. MUCHAS GRACIAS.

Hello, first of all, I am new to the forum, I'm from Spain and my English is not very good, I use the Google translator, sorry if this issue is not going here, but I'm desperate. My Nexus 5 does not light, suddenly went out, and think it would be that he had exhausted the battery, put it to load, and instead of leaving the battery icon, logo Google came out about 3 seconds and extinguished, and so on, entered a loop. Let me not go into recovery mode or lights or anything. I read somewhere, which is an internal problem button. I hope for help me.
PD / Bring an unofficial mobile store to see if I could fix and did not help me, so I lost the guarantee of Google. Hopefully I assist her. And if this is not the place for this, or is there already a solution I hope for help me, because as I said I do not understand much English. I leave the texts in Spanish and English. MANY THANKS.
up!
help please!!
If its a stuck power button there isn't much you can do except send it to LG for repairs.
Google should be able to tell how old it is by the serial number, esp if bought from them. I'd take it to bits and look my self. Could be something simple like the ceramic outer switch is not aligned with the internal switch.

Buenos días amigo, yo tuve un problema similar, pero sólo duraba unos cuantos segundos el problema. Es decir, activaba el WiFi, y la señal de teléfono se iba por completo, pero después de unos 3 segundos regresaba. Me pasó al flashear la ROM Stock de latinoamérica. Lo que hice fué Flashear la ROM stock de Brazil 4.4.4 kitkat. y Ahora funciona sin ningún problema, además agarra full señal de teléfono y wifi. Con la de latinoamérica, la señal de teléfono se ve un poco afectada.

Xiaomi Projector M055MGN Reboots over and over again

Hello there
Check I have this xiaomi projector and since yesterday it started to restart over and over again in the android 9 operating system without doing anything, I don't have time to restore, a month ago I presented the same problem but it was only a few days, I realized that it was wifi like that I deactivated it as I could not enter, it restarted, but yesterday the same problem began, everything started after the last update of Xiaomi that I installed the projector before it had not failed or it may be coincidence and I do not know how to solve it any suggestion I do not have a guarantee ticket. And I can't do anything, restart over and over again from android.
The model is my smart compact projector m055mgn.

Question Can't add google account to galaxy watch 4 / No puedo añadir cuenta de goolgle al galaxy watch 4

Hello I have a problem to add the Google account to the galaxy watch 4 I have tried all my device is Samsung, the problem started after I did an update of the watch a few months ago and I did a factory reset of the watch after that I could not re-add the Google account to the watch, I have already factory reset the watch and the phone, update the watch and the mobile several times after that and always try after updating, delete the data that was stored from the watch app in Google services, I contacted Samsung technical service and they did not suppose to give me an answer. could someone help me
Hola tengo un problema para añadir la cuenta de Google al galaxy watch 4 he intentado de todo mi dispositivo es Samsung, el problema comenzó después que realicé una actualización del reloj hace unos meses y realicé un reinicio de fabrica del reloj luego de eso no he podido volver a añadir la cuenta de Google al reloj, ya he reiniciado de fabrica el reloj y el teléfono, actualice varias veces el reloj y el móvil luego de eso y siempre intente después de actualizar, borre los datos que había almacenados de la app del reloj en los servicios de Google, contacte a servicio técnico de Samsung y no supusieron darme respuesta. Alguien me pudiera ayudar
Hi, just throwing some ideas, the same happened to me one year ago when I brought the watch and I solved it. Do you have a two step verification enabled in your Google account? If so, can you try to disable it and try again? Do you have more than one google account in your phone? Try deleting first all but one account. Is the phone Huawei? I think there is a known issue with those phones. Also please, confirm software versions both in the phone and the watch
