TLDR:

1. Load the most recent firmware onto a USB drive and name it omega2.bin. It should be in the root of the drive
2. Plug USB drive into Omega2.
3. Connect to the computer while the omega2 is off, continue to test different USB ports and cables until /dev/tty.SLAB_USBtoUART is visible (for OSX.)
4. Run the command screen /dev/tty.SLAB_USBtoUART 115200
5. Turn on the Omega2 with the reset button pressed down.
6. You should see the normal loading screen in the terminal, select option 2
7. Leave the omega plugged in. It will update and be good as new.

The Longer Version
I've finally figured it out with all of your help! Here's the outline of what I did;

I swapped cables and USB ports on my laptop until I saw /dev/tty.SLAB_USBtoUART exist while the omega2 was plugged in, but turned off. I then ran the command

screen /dev/tty.SLAB_USBtoUART 115200

I then turned on the Omega2+ while I had the reset button down. This allowed me to select options during boot. I then entered the option 2 and was successfully able to load omega2.bin from the USB. The process then continued successfully and now my omega is back to normal!

So, according to the OpenWRT docs, I "pressed a button" during startup while the Omega2 was blinking and now it's continuously blinking much faster. Okay, good, nice to see a change, but now I'm not sure how best to connect to it.

Also when I said Power Expansion earlier -- I misspoke (typed?) I actually have the Expansion Dock (this one: https://onion.io/store/expansion-dock/,) so I do have access to USB. I tried the Omega2.bin on the USB trick, but perhaps the capitalization was an issue there, will monkey around with it a bit more and see if I can figure it out.

Thanks for the help all!

I did get it very briefly to connect using another cable, then it printed a bunch of nonsense characters and froze the session. Since then I haven't been able to connect again. I wonder what's going on, I'm going to keep trying different combinations.

In addition to that, the USB does briefly flash, but it doesn't seem like anything is booting from there, it's a 16GB drive, I wonder if that's too large for the fs to understand...

Got home, installed the driver, restarted my laptop, still no omega when I run /dev/tty.* I tried restarting with the momentary switch pressed and still nothing.

Not sure what to try next... open to suggestions!

Ah, found this: https://wiki.onion.io/Tutorials/Connecting-to-Omega-via-Serial-Terminal, will try when I get back home, about to make a commute. Will keep you updated!

Thanks!!!

How are you connecting via the terminal? screen /dev/ttys0? sorry if that's a newbish question.

How does one accidentally delete BusyBox -- don't ask, it's a sad story of misused grepping and attempted space optimization...

Anyway, now I'm in the predicament where the Omega2+ refuses to start it's wifi AP services and refuses to hop on it's remembered wifi.

When I try to turn on the Omega2+, the yellow light simply blinks about every half second indefinitely. It's been a couple of hours now with no signs of stopping. Not sure what to do at this point,

List of docks/expansions:

• Power Expansion
• OLED Expansion

What I've tried so far

• Tried inserting a USB stick to the power expansion with the latest firmware in the root named Omega2.bin
• Tried restarting and holding down the reset button
• Tried holding down the reset button

Not sure how I can get this working again, please help!
