Hi guys. Thank you everybody so much for all these answers, it is so nice to see that the community is still really active. I come back on the problem after a few months because I would really like to use this Onion again. Now when I connect it to the USB the computer detects it but in serial connection nothing happen and the ligh on the Omega doesn't even turn on. I bought a CH341A to flash it with SPI, there is someone that knows how should I do it and which firmware should I flash? (Sorry but I've never done an SPI flash before)

Sorry @crispyoz, maybe I was not clear, my unit does not display this row, this is all it shows:

And nothing else.

I tried to enter safe mode from putty in windows and from screen in Ubuntu and in both cases it shows:

Please select option:
   [ Enter ]: Boot Omega2.
   [ 0 ]: Start Web recovery mode.
   [ 1 ]: Start command line mode.
   [ 2 ]: Flash firmware from USB storage.

Option [f] selected.

And it doesn't work.
Are there any ways to copy the firmware from the USB stick to the linux partition of the Omega2 through the u-boot command line?

@crispyoz sorry if I answer you only now and thank you for your help (thank you also @jmztaylor), anyway I tried an infinite number of times to press F and [Enter] to access the failsafe mode but it doesen't work. Looking at the serial capture that I uploaded, you can also notice how the booting process doesn't even initialize the Kernel. For this reason it does not display the line (I have found it on the internet) :

Press the [f] key and hit [enter] to enter failsafe mode                        
Press the [1], [2], [3] or [4] key and hit [enter] to select the debug[    5.58)
 level

It definitly stop here and than it doesn't show anything else:

@christian-lacdael Have you ever resolved this issue?

I have never used this particular Onion Omega2+ but when I turn it on for the first time I noticed that I wasn't able to find the wireless network generated by the Omega.
When I connect it to serial (I'm using the expansion dock) it shows:

So I tried to flash the last firmware from USB, as showed in the docs, but when I do it the Omega give me this error:

***************************************
* [!] This will take several minutes  *
* please do not power off your Omega2 *

*ERROR: CTL:TIMEOUT X
BBB_reset
usb_control_msg: request: 0xFF, requesttype: 0x21
value 0x0 index 0x0 length 0x0
ERROR: CTL:TIMEOUT X

I have tried with 3 different types of USB stick and it always shows the same error.
I am working to a university project and, due to the lockdown, is really difficult to receive more material from the campus so I don't have the ethernet shield to access to the Web recovery mode. There is something that I can do to try flashing the bootloader in some other way?
Is it possible to do something from the boot command line? Because I am not even able to access to failsafe mode.

Hi, I've never used the PPP protocol but, if you want to know more about interfacing SIM800/900 with onion omega 2, maybe my project can help you:

I realized a GSM module with Omega 2+, maybe this can help you:
