Comment 3 by benchan@chromium.org, Jul 13 2017 

Questions
- Was the issue observed on a specific device or multiple devices?
- Did the issue happen occasionally or under a specific condition? Did rebooting the device fix the issue?

I tested M60 and M61 on a nyan_blaze, but couldn't reproduce the issue with either T-Mobile or AT&T.

Comment 4 by vkhabarov@chromium.org, Jul 13 2017 

Customer tried on 4 devices with the same result
Issue is there all the time, he hasn't been able to connect once, rebooting doesn't help. But there is some observation - 
"Interestingly, when I reboot, for a moment, it does say connected to 4G LTE. But then after a moment, it will go away and just say initializing. "
Not sure if actual connect or just shown this way during boot. Customer tried to leave device unmanaged after wipe, did't help either.

Comment 5 by vnikolov@chromium.org, Aug 8 2017 

Hi all,

Thanks!

Comment 6 by benchan@chromium.org, Aug 8 2017 

Is it possible to obtain a unit that reproduces the issue for our internal debugging?

Comment 7 by joekon...@gmail.com, Aug 8 2017 

Yes - can you provide a shipping label?

Comment 8 by joekon...@gmail.com, Aug 14 2017 

Yes - can you provide a shipping label / shipping info?
