If you use ADB instead of terminal emulator, you can copy the text, and paste it into ADB. Never worry about syntax errors that way.yes, you will need to type it in exactly as it appears, with spaces, capitalization, etc. there is a space between the "echo" and "ro...." i think there is also a space between the ">>" and "/data/local.prop".
and make sure that after you type this in and hit enter, that you also actually type in "reboot" and hit enter. if you just exit out of TE and then reboot, the toggle won't "take".
Just FYI, but I just tried, and I have the ability to copy text and paste it into terminal emulator too. Just long press on the screen by the cursor.
