    Hi, my redmi 3 pro has vendor rom installed with usb disabled. It only charges via usb no adb no ktp or fastboot detection. Usb settings is also not showing even when forced via custom shortcut. Could you please share some solution?

    • farieznur

      sorry I don’t really get it. What do you mean with “USB Disabled”. Is it USB Debugging or what..

      • Asif

        Mobile is not detected on pc in any mode, mtp, adb, fastboot or download, only charging. Occasionally detected as unknown device, but no drivers work. Tried to access usb settings on phone but that pops up and immediately closes. Without pc can’t root it or flash with official rom.

        • farieznur

          It seems something in your phone. Is it running stock MIUI build?

          Or, you may try to reinstall the MIUI ROM using Recovery ROM (through Updater app or Mi Recovery)

          • Asif

            Its vendor custom rom, updater doesn’t work

          • xumi

            You should still be able to get into fastboot, no matter what block the rom has

  • Mackel9

      then try get into EDL mode manually. Some recent devices like Mi 5 running latest MIUI (since v7.3.x.x and up) has EDL mode disabled. If that’s the case, you may need to use Mi Engineering Deep Flash Cable –
