Problems, connecting Android ICS to Ubuntu using MTP

Please note the Terence Egan Blog where you took the instructions from is a copy of an OMG Ubuntu article.

He has missed an important step to restart your PC before running the Echo commands I suggest you try and reinstall from the original OMG Ubuntu source. Click on this link

You do not need to use MTP on the Galaxy S2 as you can use USB mass storage. Before connecting the phone via USB cable do the following:

• go to the settings
• under Wirless and network click on "More"
• select USB utilities
• click the "Connect storage to PC"

Now you can plug in the USB cable and use USB mass storage.

On more modern versions of Android, you may need to click the "More…" item in settings. This contains the "USB Utilities" item, mentioned above.
