Still having trouble with a new uboot install (9 replies)

Following a prior difficulty and reflashing back to factory, I have managed to mess up my GoFlex Home again. This is the sequence of events:

1. Mess up the gfh while installing uboot.
2. booted from usb with a debian image
3. tried to redo the uboot install, but failed
4. reflashed to factory (2.7.1)
5. successfully replaced sshd so that I could ssh in without the long username.
6. installed uboot via the install_uboot_mtd0.sh script without error other than: cannot overwrite ethaddr
7. set up netconsole via fw_setenv
8. set arcnumber via fw_setenv
9. restart failed to connect to network and no netconsole or ssh access
   flashing green then flashing orange
10. failed to boot from usb
    flashing green led then no leds at all
11. failed to reflash back to factory
12. flashing green led, then usb led flashed twice, followed by orange flashing led,never got the white flash
    tried 2.7.1 and 2.5.3

Any ideas? I do not yet have a serial cable. I ordered one about a week ago, but it is not here yet.

Below is the output from fw_printenv (I saved it before rebooting):
Is there something wrong with the uboot environment? or is there some way that I can connect to it?
I have not installed recovery
