The premise is: we want to get a file in the Data Partition under the sdcard, and then execute the ADB command from the sdcard to the PC end.
1. First, make sure that the mobile phone is already root, because do you have the root mobile phone? Do you have the permission?
2. Go to the "Data Partition" page to obtain the highest permission. Run the CMD command: su to obtain the highest permission.
3. Find a file under data and execute Cat file name/mnt/sdcard
4. Take the copied file out of sdcard.
