The fix you gave me makes difference. Right now device boot straight to Fastboot mode like in the attached image. I tried flashing couple of times the user data with different settings but without any luck. I could not track the original thread from which I flashed the first android to see what I have done already.
I went to Recovery and then to boot loader and I checked that It is indeed already locked. Which I think is correct by reading pmos docs for the device. I have fount the original post that I used to flash my device: Is this the perfect standalone tablet for HA?. I do not see anything critical on this post
