Hello moseslam1974,

You can hit the emerency reset within the sdcard door or a hard reset through the bootloader.

Here is a helpful link:

Hello Justin Kirton

I try the emergency hard reset still cannot solve the problem

after restart the table still in the same page "Too many pattern attempts"

Thank for Help

so lets try through the bootloader.

-shut the tablet down
-Switch off the device and then reboot into bootloader mode. (To get into the Bootloader mode, hold Volume up button and the Power button together.)
-Reset to factory default

Hi Justin

I try, but the Lenovo 1838 cannot go into android bootloader mode

I feel like Lenovo 1838 just bypass it and go to page "Too many pattern attempts"

Thank
