A friend gave me their Samsung Galaxy S4 I9500 because the screen is broken and black (does not display anything). So now I want to control the device from my PC. The USB connection mode is set to PTP and not MTP, so my software doesn't detect it to be able to display and control the device.

I've come across a post here almost same as my question, but I don't have the cash to buy a dock for the device.

So, if possible, how can I change the USB connection mode from PTP to MTP with a Windows terminal or with a Linux system's terminal?

  • also, does the device have usb debugging enabled? Oct 30, 2015 at 16:54
  • Hi. Sorry for that missing tag, and also the ptm miss spelled. It is suppose to be ptp and not ptm . and about the debugging,,I don't think it's enabled cause in the terminal on ubuntu it shows same as in windows when I run the command "adb devices" then it display the device serial followed by unauthorized. I bought an HDMI cable to see if I can get it workin on the tv and hopefully I can change the usb settings to MTP.

  • Hi I've managed to get the device accessible on an HD tv using the HDMI cable. I've granted debugging now. But when I plug it to my pc the pc don't recognize the device so what can/should I do now?

1 Answer 1


some phones have recovery modes xperia for example does. also there are some phones that you can connect to a usb mouse. there is a usb to micro usb converter you'd have to buy though.

  • How does this answer the question? OP is obviously using such a cable, or there wouldn't be any physical connection between the device and the computer at all. And what does recovery mode have to do with it?
