Enable MTP using ADB

Question

How do I enable MTP mode on an Android phone, solely using ADB on the command line? The screen cannot be used and I need to access files. I have USB debugging enabled, though.

adb shell svc usb setFunction mtp

does not work, oddly.

Solution 1

you lacked the "s" in "setFunctions".

 "adb shell svc usb setFunctions mtp" worked for me in Android 9 (lineage OS).

Solution 2

On my galaxy S8 (android 9.0 i think), i used:

adb shell svc usb setFunction mtp true

once my phone had been connected to the computer and USB debugging enabled

I think the final parameter "true" on the end is optional but is false by default. I'm not exactly sure what difference it makes all I know is that without the "true" it didn't work.

Does your Android device have a custom recovery such as TWRP?

In my case I had to use "setFunction". Android 7.1.2 (LineageOS for microG 14.1)

This worked after I connected with TCPIP and accept the authorization dialogue on my phone. ``` adb connect 192.168.1.53:5555 ```

I had the same issue on the athene running lineageOS 15.1 unofficial.
