Emulator (weaponised)

I am trying to installing & Configuring Nexus Root Toolkit but not successful. When i tried to unlock, it say “fastboot device was not found”. Please assist. Note, i am trying to do it on laptop not phone

Your android device should have fastboot installed for this to work I think.

hello Apurv,
Thanks so much for your reply. Please are you saying i use do it on android device not on laptop? Have tried on laptop, it requires me to use USB as connection.

Even if you are using emulator, you should have fastboot installed in that emulator. Otherwise you can use any rooted phone with fastboot installed using a USB
