This mpkg software will dump a backup of your cg34 cg37 cg41 cg42 cg43 to BackupOS folder in your memory card. That is very required when some new ROKR E2 user find new firmware on his phone - he can dump it and share to the community

When you start it you will hear "Ding". After 5-10 minutes you will hear "Ding-Dong", which means that the backup is done
