Manually modify Android database data

Manually update settings in command line [first written by Steve Guo, please keep the mark if forwarding.]

Android saved settings in a database file which is/data/COM. android. providers. settings/databases/settings. DB. for some settings, Android does not support set them on the GUI. so we need find another way to set it. here it is. I will use set "device_provisioned" as an example.

Android use sqlite3 as the database. So we can use sqlite3 to manage the database file.

$ Sqlite3/data/COM. Android. providers. Settings/databases/settings. DB

The above command will open the settings database. Then you will enter into sqlite3 command line.

First we can check how many tables existed in the database. Here lists the result.

SQLite>. Tables
Android_metadata bookmarks gservices
Bluetooth_devices favorites System

The settings we try to set lies in "system" table, so then we list all items in the table to view the current table information.
SQLite>. Dump System

Pay attention to the first line about table information. the text marked with red will be used when writting SQL statements. assume we want to set "device_provisioned" to 1, we can simply type the following statement in the sqlite3 console.
SQLite> Update "system" set value = '1' where name = 'device _ provisioned ';

You can type ". Dump System" again to check whether the modification is valid.
