Is this process correct: Connect USB cable to the phone and mount it from the notification window. Open up a folder view on my Laptop for the mounted Eris. Copy all the files/folders from the Eris to a folder location on the Laptop. Manually update the Eris. Reverse the process on the USB connected/mounted Eris copying and overwriting all files from the Laptop back onto the Eris. Bottom line question is when the files are returned back to the Eris will the overwrite screw any updated files? Do I need to be selective of which files/folders I backup then overwrite? Thanks in advance.
