There are three states a laptop can be in:

1.  secure, with no developer key, (prevents access to ok prompt),

2.  secure, with developer key on internal storage, (allows access to ok
prompt),

3.  unsecure, (allows access to ok prompt).

Given the evidence you've presented, it seems like a developer key was
installed, but then a new build os851 was installed, which overwrote
that developer key.  "wipe out".

So I suggest the following:

a.  obtain and present the developer key to the laptop, by following the
documentation in the section "If you wipe out your developer key", at
http://wiki.laptop.org/go/Activation_and_Developer_Keys#If_you_wipe_out_your_developer_key
from either the "Insert a USB flash drive or SD card with your developer
key on it" text or the "Once boot completes you can restore your
developer key back to NAND flash" text,

b.  obtain the ok prompt, (it will not be obtainable unless the correct
matching developer key is presented in step a, so if this step fails go
back to step a),

c.  use "disable-security" in the correct fashion, by following the
documentation in the section "Disable the security system", at
http://wiki.laptop.org/go/Activation_and_Developer_Keys#Disable_the_security_system
