i'd suggest a power supply of 5V 2A minimum. usb lines from computers and/or phone chargers most of the time do not supply the current that the omega2 needs to boot up. especially at the point where the omega2 attempts to connect to a wifi router and can generally require for a brief period of time current in excess of what a usual usb line or phone charger can provide.
i have recently become interested in the Onion Omega2+ and the various modules and plugins as well as aftermarket pcb boards which give the omega2+ greater reach into the environment.

RE: Wifi Seems to Connect then Immediately Disconnect?
you will need to get a copy of the *.bin from the onion server somehow which requires internet. you can try to download directly from server.
http://repo.onion.io/omega2/images/ and then flash that.
look in the documentation for the instructions.
look for download to usb storage.
if you have a dock with usb then,
otherwise a serial cable will help in the transfer.
RE: Would I fry my GPS extension if I plugged it into and used it on a Raspberry Pi?
you might find some clues by researching either the hologram dash or the hologram nova. the dash was in development about the time of the onion gps module and the nova is the newest gps module which is similar usb module. there are several guides on net explaining how to setup nova on rpi which might help setup onion gps on rpi.

there might be some info in these documents that would help,

RE: Omega2+ Shuts Down and Doesn't Restart
maybe create a method to data log the power [volt/amp] supplied to the omega2. you would then have a record of what was being supplied immediately prior to shutdown. maybe heat build up over a day or so affect the output of the power supply. maybe the script you are running affects the load on the omega2. i suspect that 200mA max of supply [if it is that] might be not enough under some conditions. maybe what ever you are using to supply power to the board is turning off/sleeping at some point because the omega2 is not using enough current.
RE: How to properly shutdown Omega-2?
@CAP-33 i have been issuing a reboot from a ssh terminal and then watch the device and when the LED goes off i remove power. so far i have not had an issue with data loss. i do remember when the device was first released the suggestion from an onion rep was just unplug it at any time.
RE: LED on Arduino Dock 2 question
@György-Farkas the out of the box state is continuous illumination. that is the manufactured normal state. any other state needs to be arrived at by user software control. that is a user defined state. look, you can beat this to death if you want, but i'm looking for help which you seemingly do not want to offer or can not offer. so why the trolling? please, just leave it effing alone.
