Possible problems - phone defaults to USB for charging, not for file transfer.

Title. I've followed directions word-for-word. However, starting the device in fast boot & plugging it into the PC will not cause the device to appear. I Mi Unlock also can not detect it.

How am I messing this up? What can I do to fix it? Do I have a bum phone & need to return/replace?

  • Logged into Mi account
  • Mi account sync on
  • Find my device on
  • Developer options enabled
  • Enable USB debugging enabled
  • OEM unlocking enabled
  • SIM card in, wifi off, mobile date on
  • Mi Unlock status activated

  1. All of the above done
  2. Initiate fastboot
  3. Start Mi Unlocker & sign in
  4. Plug fastbooted phone in
  5. Phone not detected by Mi Unlock
  6. Not appearing in Windows Explorer
  7. Use CMD to search for devices, none found
  8. CMD -> adb devices returns nothing

i've a similar problem, for me the problem was the usb 3.0 port, with a fresh start of win10 i can see the phone connected in fastboot mode, when i open mi unlock the phone disappear and after is impossible to be recognized until a restart of win10. The only way for see the phone detected by MI unlocker was to use and usb 2.0 hub connected in the usb 3 port. Use a usb 2.0 port if you've or try with another computer.

I used Windows 7 and it worked perfectly first time. I think (as always) it's a windows problem.

What worked for me is transferring the folder of mi unlocker to the root of C: and reinstalling adb drivers

In the Mi Unlocker app, in the top right corner there's the settings button, go there and look for the "Install drivers" button. That worked for me.
