I think that I somehow set the flash protection bits. Is there a way to recover, or is my board now a paperweight?

Running Jflash when I connect I get a dialog "Protection bytes in flash at addr 0x400-0x40F indicate that the readout protection is set"
However when I tell it to go ahead and mass erase it doesn't clear the issue.

Running J-Link's "unlock Kinetis" command results in "Unlocking device...Timeout while unlocking device."

When I attempted to connect to my device I got the following output:

Connecting to target via JTAG
InitTarget() start
InitTarget()
Device will be unsecured now.
Timeout while unsecuring device. Erase never stops.
InitTarget() end
