DISASTER - pplug pro blinking green, won't boot or connect

[DonnyBahama]

I followed the procedure here and everything went fine until I got to step 14 (pacman -Sy udev-automount). Pacman itself needed an update but it would not update. (I don't remember the error message.)
I searched and found a thread that said it works if you just say no (don't update pacman). It still didn't work.
I tried pacman -Syuf and it didn't work, either. It did a bunch of stuff then gave an error (that I don't remember) and said no changes were made (or no updates were applied or something like that.)
Next I tried pacman -S udev-oxnas
This worked and afterward, I was able to run pacman -Syuf
After that I was able to update pacman but after doing so I was UNable to run pacman -S udev-automount because it said it couldn't find it.
Well, in the process of running the above steps, there were various conflicts, and in order to proceed (and complete the steps successfully) I had to allow it to remove some files. (I suspect, now, that this was a mistake).

I figured the best thing to do was to start over, so I went back to step 7 and removed and recreated the partition on /dev/sda1. When I tried to write the changes, it said the system was using /dev/sda1 so I'd have to reboot.

After rebooting, I could no longer ssh into it. I checked my router's DHCP clients and my pogoplug wasn't listed. I powered down again, removed the thumb drive and booted up again, expecting it to boot as normal. It won't. In fact, it still won't get an IP address and the front LED is blinking (rapidly) green.

I'm totally stuck. Please help!

1) woo, exact copy of official instructions.. pretty direct ripoff. - Use the Official ones next time.
2) Good new is, you've just not actually read the instructions.

Go to the platform page (main site > platforms > armv6 > pro/v3), click over to the install page scroll to the bottom, and follow instructions. If you didn't read the massive note about upgrading.. that might be why.
