Added simulated external display in Developer Settings and can't boot now

Got my S3 Mini with CM11 stuck at boot after adding external display simulation in Developer Settings. Just after that UI froze and I had to reboot. After that it freezes on "Android is upgrading" popup and the progress circle isn't even running. I tried going to Safe Mode but the only difference is that the progress circle is running all the time but nothing happens for another hour. Logcat says something like this: I/DisplayManagerService( 2137): Display device added: DisplayDeviceInfo{"Nakładka nr 1": 720 x 480, 60.000004 fps, density 160, 160.0 x 160.0 dpi, touch NONE, rotation 0, type OVERLAY, FLAG_SECURE, FLAG_PRESENTATION} E/gralloc ( 1671): gralloc_alloc: gralloc_alloc_framebuffer (google) failed, Out of memory E/FramebufferNativeWindow( 1671): fb buffer 0 allocation failed w=480, h=800, err=Out of memory Is there any way to remove the additional display without having to do data wipe? I have full access to ADB and recovery. Just this one thing stops Android to boot further.
