If you just got your Droid Charge and this is in fact your first fling with Samsung devices, there is a very important program that you will need to become familiar with if you were to try any of the fixes posted in this site. Odin, named after the Nordic God, is essentially a RUU for most Samsung Galaxy devices. Simply put, Odin will allow you to flash tar images to your Android devices. One very useful application of this is to be able to back up and restore the complete system. Some of these images must be prepared in order to be flashed and XDA Recognized Developer imnuts provides us with a useful guide on how to make these custom images yourself. As always, please be sure to read and fully understand the instructions in order to minimize the possibility of damaging your device. Also, any feedback about the guide will certainly be appreciated.
This will allow you to backup your system and create custom Odin images for restore purposes.
