You need to enable the developers option on and usb debugging on in it. also put the phone in charge mode only from MTP. enable diag using ##DIAG#. Install the drivers again. change USB port also.

Unable to enter USB debugging mode

Hello all,
I purchased this phone a month back and would like to install custom roms/root it etc.
I am unable to get my phone to enable USB debugging and allow access for my PC. (I have a unlocked bootloader). The notification (prompt) for USB Debugging which shows up the phone (asking if one wants to grant access or not) doesn't show up. Hence I am unable to use adb or fastboot to install TWRP.
I have tried using the cable provided by the company on both USB 3.0 & 2.0 ports to no avail.
I am aware that there is a "How to Guide" under the News/Discussions section. However, it hasn't helped me much.
Any possible solutions?
Thank you
PS- When I connect to pc using USB cable I get the prompt asking me if I want to use it for file transfer,PTP or no data transfer.
Are the drivers properly installed?
What does the device manager show, when your phone is connected via USB and USB debugging is switched on?
What happen if you type "adb shell" when your phone is connected?
Enable it in developer option
Allow USB debugging and USB debugging Security Settings) in Developer Options
