Many tablet users Android very often encounter a problem related to blocking the device with a graphic key or a regular password. This usually happens due to the owner's inattention or forgetfulness. There are many ways to unlock on the Internet, I slightly corrected one of them and, after more than a hundred unlocked tablets, decided to describe the entire process in full
I would like to warn users in advance that this method works on tablets with Android OS that run on chips from Allwinner (A10, A20, A31, etc.).
The process of resetting the password on the tablet using a PC
First you need to install the drivers ADB. On all tablets with Allwinner inside, ADB drivers are installed using the same technology
Now download ADB drivers for Allwinner and install
Turn off the tablet. Press and hold the Vol+ button. Connect the tablet to the computer. And press the on/off button 3 times.
Now open the device manager:
Right-click on the "My Computer" icon and select "Device Manager" or "Control - Device Manager".
Now in the list that opens, find the "unknown device" or the device with a yellow question mark. Right-click on it and select "update driver" in the open window, select manual installation or search on this computer, then select installation from the specified location. Click "browse" and select the USB driver folder. Click select then next. Wait for the system to install the drivers.
After installation, we need to connect to the tablet via ADB
Download and unpack archive with ADB
In Windows, launch the command line
- -Click the Start button, click All Programs, and in the Accessories folder, click Run.
- -In the Open field, type cmd and press enter
In the window that opens, you need to type cd and drag the ADB folder( not ADB(2)) on this inscription.
Note: the folder must be located on drive C
Now, to access the tablet, you need to connect the tablet to the computer, and in the command line, type adb shell
After pressing enter the following message will appear:
root@android:/ #
or
shell@android:/[/su_box]
Next, enter the lines one by one, pressing enter after each line.
cd /data/data/com.android.providers.settings/databases
rm settings.db rm settings.
db-shm rm settings.db-wal
All. Files responsible for blocking have been removed.
Now all that remains is to enter reboot and wait until the tablet reboots.
After rebooting the Android tablet, the system will start without asking for a password. Now you need to copy all data from the tablet and reset to factory settings to continue working with the device.
I understand that the password reset process is a bit crude, but it gives 100% results in a couple of clicks.
If you don't want to mess around with ADB, then download archive, unzip it. Connect the locked tablet to the computer, open the folder and run the file password_reset.bat
The process will start
After restarting the tablet, the password request will disappear.
