Display MoreThanks Henkie for your fast answer.
It's in the Z8 section posted, so i should be correct. And his device is mentioned in the thread name.
Try to find this please:
Go to home menu ->Settings -> Storage & Reset ->if block installed, you should see menu entry "Check for configuration update" -> Highlight the configuration line, then press 0 (Zero) -x10 times -> It will factory reset and unblock the entire device.
And let me know please
Ok, this one I could find and it factory reset the device when I pressed 0 x10 times.
And the problem IS SOLVED!!!!
Thank you so much, Lucky13 and henkie for your help. I was going mad with this, you guys are the best!!!
