Kustom42's advice of rootign the phone would not be extremly helpful as you will be able to at least read
any data you need.
It sounds like you may be new to adb.
Are you new to using shells on Linux/Unix?
Do you know the specific location and names of the files you are looking for?
Files you would have saved are in /mnt/sdcard (but this can vary on each phone).
A recursive adb copy from that directory would look like this:
adb shell cp -R /mnt/sdcard ~/android-backup
That would copy everything from /mnt/sdcard to a folder called android-backup in your home directory (you must create the folder ahead of time).
It looks like you have the same topic posted here
I would not categorize these as different issues.
