Default [Q] Screen damaged - phone locked - adb unauthorized - how to access data?

Hi.

I just switched my D802 on yesterday morning and got the screen attached - reboot just show black and this screen again - it seems that the whole screen just went south.

Even though I will try to get a replacement (it is a testing devices) I want to backup my data. The phone and its software (cm11) still works, I just got an alarm this morning.

I could just erase everything with Android device manager, but I would like to save my messages, call logs etc.

Problem: I used a screen pattern to lock the device. I already managed to change it to a passphrase using android device manager,but I don't know any way to unlock without the display -
with this lock, adb access in unsuccessfull (device unauthorized). Is there any way to unlock the device?
Any help would be really appreciated - keep in mind - no access via touch is possible - see device picture.

adb:

Code:
Select Code
C:\>adb devices
List of devices attached
019537e89498f242        unauthorized


C:\>adb shell
error: device unauthorized. Please check the confirmation dialog on your device.

you SHOULD be able to reboot to recovery using power/volume down combo
from there you SHOULD have adb access and can adb pull the /sdcard partition from the phone.

You're right - but it is very hard to press the buttons accordingly without any visual confirmation...

Finally I got it... it was quite a struggle, but I could pull all necessary data from the dead phone, thanks for the hint.
