2106f Error Code after Internet Recovery Attempt

Anyone ever get a 2106f Error Code after Internet Recovery Attempt? What next?

Background: Macbook Pro (late 2011) shows startup progress bar, goes ~ 1/10th of distance, freezes, then goes black after ~2min. Did this:

1. Clean startup attempt (shift)

2. Zapped PRAM (option command P R)

3. Reset SMC, Startup

4. Attempted Internet Recovery process (Cmd R) over ethernet connection, but after several hours, got the -2106F error.
