Mi5 No Wifi Or Camera Since Update

[onabike]

My newly purchased Mi5 3/32 has gone wrong since latest update.
I bought it in China in May, it worked Ok. Upon return to Europe I downloaded play store chrome etc, and it worked even better. The weekend before last the phone did an auto update, and since then the WLAN will not turn on ( move button to on position, moves straight back). The camera either crashes or gives a completely black picture and in the incall Ui does not work, and keep receiving messages that the finder has crashed.

I have MIUI 7.3.4.0 and have done a reset back to factory defaults (full chinese mode) same faults still there.

Any ideas antone on what to do next please?

Try a factory reset with mi pc suite

Cant connect to the suite as it says my phone needs updating first!

 

[Cecco]

Connect to suite in fastboot mode

Connect to suite in fastboot mode

Please tell me how to do this.
All I get is a pic of a phone with a cable inserted, but nothing happens

Same problem at my Mi5 with 7.3.4.0! I send my phone back to seller. I will get new one.

I thought this what I had done! Held volume down button whilst switching on, release on button when MI appears.
I have now tried this numerous times, and same result each time.

Please can you give full instructions to a complete novice.

try volume up plus power button

That works, in Fastboot mode now, but still cant connect to PC. What should I be doing now?

maybe you dont have drivers. install fastboot and adb drivers and you will be okay. search on google fastboot and adb drivers and open xda page, they have released new version supporting new android api for marshmallow so you will be okay. rememeber phone disconnected during driver installation
