[Guide] Recover MTP setting when connect via usb cable

[theoblackhawk]

In this post I will describe a simple method that I followed to recover the option of choose MTP connection when using a usb cable to the PC.

After root with SuperSU I noticed that when I plugged my phone to the PC using the usb cable, I did not have the option to "mount" as MTP anymore.
Therefore I could not transfer files from my PC to the phone in a easy way. If you want to continue with latest SuperSU you have to do that:

1. Edit your build.prop file adding those 2 lines at the end:

persist.service.adb.enable=1
persist.sys.usb.config=mtp,adb

2. Close and save it
3. Enable USB debugging in developer options
4. Select MTP in USB Configuration
5. Profit
