Hello @Chris Stratton
I'm confused ,Does the only 3.3v one line from other source will power Omega?
I think 3.3v and gnd should come from the same source in order to power omega on, or i missunderstood something.
Could you write a schematic please.
sorry for my English ,i'm not good at English. Hope you understand me.

I think nothing happen when i pressed button, so now i bought usb to ttl with CP2014 chip and connected to omega and computer by using 4 pin (i use PuTTY)

omega2+ ------- usb
vin --- 3.3 v
gnd --- gnd
tx0 ---- rx
rx0 ---- tx
result is blink these :

here is video clip link : https://www.youtube.com/watch?v=lLD7kF-zbLI

OK, gnd to rst and 3.3 vin to fw rst then press (gnd to rst )10 second then release right? while press reset button led on board will off ? and after 10 second led on board keep blinking am I right?

Dose it need a Resistor?

I don't notice the what version of the new firmware when i upgrad by command line,
No dock sir.

Hi all, Can anyone provide picture or schematic for factory reset without any dock (omega 2+).

I just got omega2+ today it's very cool,but after i connect by ssh and upgrade firmware version it's look ok until some word say something and end with e/w blink and i lost connection with putty ,and my omega2+ shut down itself, so i connect to power it again and i can not see omega's wifi.
