@Boken-Lin Ok I'll try that. Thanks for the help!

@Boken-Lin I followed the instruction to de-brick the omega and I got to the end of step 5 where I successfully connected the omega to my MAC's ethernet port and I got the message that the http server is ready at 192.168.1.1. The problem is that when I go to 192.168.1.1 nothing happens. It says unable to access network.
Regarding ext4 formatting...do I need a linux machine? Can I do it from a MAC or using a VM?

@Boken-Lin Yes I do happen to have an Ethernet expansion. Please let me know what to do in order to make it work + format my drive to ext4.
thanks

@Boken-Lin I held the reset button down for at least a min and nothing happens....same error when i try to restart it. I tried a different dock but same thing. I'm assuming the reset button is the one next to the power switch on the main expansion board. Is there another way to reset to factory defaults? I tried multiple times and it's not reseting.
I also didn't format the drive to ext4...are there instructions on how to do that?

I followed the instructions here: https://wiki.onion.io/Tutorials/Using-USB-Storage-as-Rootfs
I started step 2 and plugged in my usb storage device and the omega recognized it and installed /dev/sda
/dev/sda1
/dev/sda2
I then followed the next step of the instructions:
mkdir /mnt/sda1
mount /dev/sda1 /mnt/sda1
Then it just stopped saying that the disk was full. My USB storage device is a 256GB ADATA 2.5" SATA to USB drive.

I turned off the omega and turned it back on but now it wont load (amber light stays flashing). When I connect it to my laptop these are the last few line I see in the console:

/etc/preinit: line 1: cat: not found
/etc/preinit: line 1: cat: not found
/etc/preinit: line 1: grep: not found
[   81.880000] random: nonblocking pool is initialized

The amber light never comes solid. My questions are:
How can I reset my omega?
In my description above...should I have chosen sda or sda2 ? what does it mean that in my case it installed 3 sda instead of just sda1 like in the example?
Is my usb storage drive compatible?

If anyone can help it it will be greatly appreciated!
