The "broken pipe" exception means the process on the other end is gone.
This won't give a SecurityException, because it's not Java that's checking the permissions. Connect to the phone via 'adb -d shell' and type 'su' followed by Enter. What happens? (You may need to add the tools directory from your SDK to your path first, or type the entire path to adb.exe -- or equivalent if you're using Linux or OSX. Use -e instead of -d if using the emulator instead of a phone. See the docs if you have more than one). If it just works, then download Better Terminal Emulator (I think there's a free version but the better one is better) and try it from there. What happens? Check your $PATH variable, and use that to locate where the su program is located. Supply that in your exec() call. But be aware that the path is likely to be different on phones rooted via a different procedure! Using 'su' -- and doing anything requiring root permission, or anything using anything added by a rooting procedure, is not supported, so you'll have to do considerably more legwork to iron out the compatibility issues. Not to mention, you'll be limited to customers who have voided their warranties and rooted their phones.
