I loaded a Cr1084 application into a Cr1082 (because that's all I had available for testing). After about 2-3 minutes of running I got a 2 Hz RED LED (run with error). The unit now appears to be stuck in the boot process (5 Hz green LED). Here's what I've tried so far without any success:

1) Re-start in system screens (held 2 keys while powering up).
2) Re-start in recovery mode (held 3 keys while powering up).
3) Connect via FTP

In all three cases above the unit responds the same: 5 Hz green LED.

Is there anything else I might be able to try to recover the unit? Thanks.
