This has been quoted from the AAHK thread. I'm just copying it and in future, you could do this your self since absolutely EVERYTHING on xda has been explained about a million times before.
Q: Do I need to plug in the phone?
A: Kickban. If you know how to enable usb debugging without a USB connection, then I'll change this policy. In the meantime, asking such a question just makes me think you have not read anything and/or have dedicated yourself to being an idiot

[Q] How to make my phone appear in USB mode?

When I connect my phone to PC, everything is perfectly fine. However, I want it to run in USB mode instead of appearing under 'portable devices'. This is because I want to run a software to recover a lost file and this software requires my phone to be in USB mode. Anyone knows how to do it?
Thanks

It isn't possible to use any recovery software with jelly bean.

Thanks for any help.

Can you boot to recovery? Should be the power + volume down combo until the logo comes up.
Alternatively,
Have you installed ADB and fastboot drivers?
Can ADB see your device when you're plugged into the computer? Perhaps you can get into bootloader mode through ADB if so.
Connect LG G4 to your computer.
On the PC, access the Android SDK folder (download it if you don't have it).
There, open a command prompt window by pressing shift + right click on any blank area.
In the CMD window, execute the command " adb reboot bootloader " without quotes. If you haven't enabled USB debugging, you may be out of luck.

Tried but not working

1. Point us to that dubious unlock app please!
2. Very very often an issue occurs because a user do not use the correct commands or important error messages are thrown and the user do not show. So please write EXACTLY what you do. For example the exact command to proof the connection (e.g. "adb devices") and the exact result. easiest and best way is to just make a screenshot of anything.
3. Another example is how to you try to get into download mode? There are some guides which do not work so explain what you do always helps others to help you.
I use the following method:
Pull out battery
Plugin USB cable connected to the pc
Press vol Up and keep pressed while putting battery back in place
4. To avoid driver issues you should consider to use FWUL ( https://tinyurl.com/FWULatXDA ) for anything else then kdz flashing (this requires windows)

Hi, Thank you very much for taking your time and energy to answer me. I used Z3x to Factory the LG G4 (T-Mobile) I wanted to flash it by downgrading before to see if it could work. this is how I break the phone with the downgrading. So now the phone is not recognizing by the computer as Modem when I plugged in, I see it only as External Drive.

Ok... Since I have no intention to root until Huawei pushes the Oreo and Facial Recognition updates, I have kept USB Debugging "OFF" and set Select USB Configuration to: Media Transfer Protocol (MTP)
Then, I attempted to do what you are trying to do... and it worked perfectly..
So.. Do This:
Step 1 Click on your windows icon and in the search bar type "CMD"
Step 2 Set USB Configuration to MTP.
Step 3 Again I had Debugging off.. you can try it with it on if you like.. either way turn off your device.
Step 4 Hold down the Vol-Down button while plugging your device into your USB cable connected to your computer.
Step 5 This will turn on your device and put you in Fastboot Mode.
Step 6 Now go to your ADB Command Line and type "fastboot devices"
You'll see it.....

Grab adb and fastboot from here Extract and open folder, hold shift, right click in the folder and open command prompt. Type 'fastboot devices' to verify that your device is connected. If all set, then type 'fastboot oem get_unlock_data' to get your string and follow the steps here

Make sure you're using oem cable, 2.0 usb port from the motherboard, not a hub port from the front of the pc. Also, make sure you're not putting the 'quotes' in the command.

i run.. .\adb devices for some reason my comp only runs it if you use .\ in front of the commands . then i use.... .\adb reboot bootloader ...the phone goes into bootloader .. then .\fastboot devices and it shows the serial, then .\fastboot oem get_unlock_codes and i was getting a cursor that stays until i close the program but with new link someone gave me for adb it says failed unknown command

1. T-mobile is unlockable
2. Turn on developer mode and Allow OEM unlock
3. On Windows PC, open adb via CMD. Connect your phone and type:
adb devies
You should allow authorisations on your phone.
4. Enter bootloader mode (maybe wait for the PC to recognize the phone). Type command:
fastboot oem get_unlock_data
5. Follow these links that others gave. Make sure Motorola and Google USB driver are installed.

Check usb port, cable, and adb/fastboot files. 95% of the trouble people have with flashing and/or fastboot commands can be attributed to one of those.

No that didn't work
