Hi Guys,
My huawei Ascend P7 has stopped Prompting me options when I plug it into my PC or Laptop how do I get my phone to provide these options again?
:-
Check your cable. Maybe try a different one. Also, make sure you have the drivers installed on the computer.
You can also get to that prompt by enabling developer tools. To do this, open settings, scroll to the bottom to About phone, find the Build number, and tap on that a bunch of times. Eventually you'll see a prompt saying something like, "tap x number of times to become a developer." Keep tapping and you'll see a new one that says something like, "Congrats, you are now a developer." You've now enabled the secret dev menu.
Now hit the back button to go into the main settings menu. Right above About phone, you have a new option to go into Developer options. Under the Networking sub heading you should be able to see the option to Select USB Configuration. That should be the menu you are looking for.
Hopefully that helps!
