A friend played with the broncho A1 lock screen. As a result, the mobile phone is locked and the Google ID cannot be entered (I can do it here ). Recover the system, and he didn't want to reinstall all the software. So I studied how to modify the system settings on the command line. He is not engaged in technology, so I asked him to change the settings. DB name or delete it, but it was a bit violent. Here we will introduce a slightly more troublesome but user-friendly method.

1. Compile a sqlite3 command line tool (external/SQLite/Dist) first ).
(You Need To comment out local_module_tags: = debug line in Android. mk)

2. Upload compiled sqlite3 to A1.

# ADB push out/target/product/Littleton/system/xbin/sqlite3/Data

3. Use a serial port or ADB to connect to the A1 terminal.
ADB shell <br/> # cd/Data <br/> # chmod 775 sqlite3

4. Use sqlite3 to set up a database in the data system.
#./Sqlite3/data/COM. Android. providers. Settings/databases/settings. DB

Modify Table content:

SQLite> Update System set value = '0' where name = 'lockscreen. lockedoutpermanently '; <br/> SQLite> Update System set value = '0' where name = 'lock _ pattern_autolock '; <br/> SQLite> Update System set value = '0' where name = 'lock _ pattern_visible_pattern ';

Exit database:

SQLite>. Quit

5. Restart broncho A1:

/Data # reboot
