Hi,
recently i received a unbranded 7" tablet with ICS firmware which was locked permanently because of too many wrong attempts to unlock device.
i used adb to break the lock and successfully booted it again for regular use.
i have searched a lot for a solution but dit not find any effective solution for the device. so i experimented on the device and it worked for me and i am going to share it to help others .
First you require the following things:
1. usb debugging active on your device(if debugging is not on then you cannot use this method)
2. adb shell on your computer (follow this thread for adb http://forum.xda-developers.com/showthread.php?t=502010)
3. usb cable to connect your device to your pc or laptop.
4. Usb debugging drivers if not installed from here http://www.topnotchtablets.com/installADBdriver
5. a little :good:luck
How to unlock:
1. connect your device to pc and install drivers.
2. open the folder where you installed the adb for dummies and search for adb.exe
3. right click holding shift on the free space in folder containing adb.exe and select open command window here.
4. typre following commands separately by pressing enter after each line:
your device will reboot and you will not have any password to enter and a free unlocked device again.
NOTE- this will not work on all devices but it will work on unbranded , chinese and local tablets . i confirmed this method on CHAMPION WTAB 7.2 AND KROSS tablet ics. please be carefull not to delete the /data folder, you have to delete data folder under data folder(/data/data). so just enter the commands as they appear and it will be fine.
Feel free to ask any question if you need help.
