I have two argons with this issue and it only has shown up recently. I start an Argon (no issues). Try to add a Xenon (tried two different ones, one known good, one new) and I get Pairing with the assisting device, and eventually Failed to connect to your mesh device Please Try again. I can connect to the Argon through the phone app without a problem (for “maintenance”).
Not sure why, but yesterday when I was attempting to pair my Xenon’s with an Argon I had to “Try Again” multiple times before it worked. It finally did work.
Which version of the app are you using? (You can check this by going to Settings -> Apps, tapping on the Particle app, and scrolling to the bottom of the screen)

Sent another email today to Particle support. It has been days since my last reply.
My working (for months) Argon is now dead since update
My new Argon is dead since update
my 5 Xenons, no idea since the Argons are dead.
The rest are still in boxes, no reason to open.
Email working with Tech Support basically an email every couple days been dealing with dead equipment for over a month. No urgency from Particle. Very disappointed.
One Argon and One Xenon were working wonderfully which prompted my investment in additional devices. Now, none work.

@jslawsky - after the update, place the device back in DFU mode and flash particle flash --usb tinker.
particle update does not overwrite application firmware, it overwrites Device OS only. you need to overwrite both in this instance, forcefully, by using DFU mode.
Have you tried it?
If you did, you should have seen this
>particle flash --usb tinker
!!! I was unable to detect any devices in DFU mode...
> Your device will blink yellow when in DFU mode.
> If your device is not blinking yellow, please:
1) Press and hold both the RESET/RST and MODE/SETUP buttons simultaneously.
2) Release only the RESET/RST button while continuing to hold the MODE/SETUP button.
3) Release the MODE/SETUP button once the device begins to blink yellow.
Error writing firmware: No DFU device found
I believe an issue currently exists with the DHT library and Device OS post 1.2.1, in which memory allocation became explicitly forbidden in an ISR or Event Handler.
