Thanks for the reply - I have solved this issue!
With cold start power on all I got was the Asus logo in the center and the Nvidia logo in the bottom right. Although the Unlock apk started up OK it stopped prematurely by the Google sign-in trap. It was puzzling that Google sign-in would not accept my password and instead just looped. I double checked the PW by confirming the same password opens the same GMail specified account using the GMail app installed on my same TF201 tablet.
I solved the situation by deleting the Google accounts under Android settings. Now it confirms unlock status. I also rooted the TF201 easily using MotoChopper 1r1.
