Sorry, but this site does not work like that (sending you emails in a specified format). We are a Q & A site, that means we hold both parts together. Besides, your question has already been answered multiple times here, see e.g. Cannot unlock tablet as have no internet connection? –  Izzy May 27 '13 at 6:25
    
Oh, I did not know that. I have never used a site like this before. Thank you anyway. –  user34728 May 27 '13 at 14:25
    
You're welcome. Though I recommend at least having a look at the FAQ of our site(s). Might save you some headache :) And won't take that much time, as we tried keeping it short to not scare people away #D –  Izzy May 27 '13 at 14:59

Suppose your tablet is in WiFi or in airplane mode? And you can't unlock it without? There's a way to solve this:

Open CMD:

Change directory to the android SDK platform tools (for example C:\Program Files\Android\android-sdk\platform-tools)

Type following commands in CMD:

  • adb devices (verify device is identified by pc. If not reconnect device and try again. it should display “device” with a serial no)
  • adb shell
  • cd /data/data/com.android.providers.settings/databases
  • sqlite3 settings.db
  • update system set value=0 where name='lock_pattern_autolock';
  • update secure set value=0 where name='lock_pattern_autolock'; (for some devices update “system” is enough but I had to update “secure” too)
  • update system set value=0 where name='lockscreen.lockedoutpermanently';
  • update secure set value=0 where name='lockscreen.lockedoutpermanently';
  • .quit
  • exit
  • adb reboot

Now your device should be unlocked. If not do this step too:

  • adb shell rm /data/system/gesture.key
