Issue: After root access, the file Explorer with Eclipse comes in to access the storage files for each app under/data/data and cannot be opened. After replacing another device, the situation is normal. Some models of Sumsung are still unable to read and write system files after acquiring the root privilege system, this time we need to use ADB to give permissions to the folder
Workaround: After configuring the ADB, cmd goes to the command line, enter the following command sequentially by ordinal
1. ADB shell
2. SU (after the PC has finished this command, the Android device will normally prompt for ADB authorization, select authorization)
3. Cd/data/data
4. Chmod-r 777/data/data (This command modifies all access rights to files and folders in this directory)
If you only need to modify a file using chmod 777filename
This allows the contents of the/data/data file to be viewed.
