How can I connect my LG H 840 phone to Google servers in China?

I had to do a factory reset because of the UI system has stopped. Aparently it was cause by Google autoupdate and my battery problem. I tried all kind of programs in the end I hard reset the phone. Now I am stuck because of the factory reset protection, the phone connects to internet but not to google servers. It doesn’t work in China whiteout Vpn. Tried to follow this article and many others, no succes. I have internet, Vpn but no wired connection. Is there something else I can try?

Connect a Chromebook to the internet with a USB Modem?

Main question: The Chromebook is definitely recognizing the dongle as an internet device because an “Ethernet” option becomes available in the Network settings as soon as I plug in the USB, and when I take it out it disappears. It seems that the Chromebook is only having a problem configuring the proper settings, but if I know which settings to change seems like it should be able to work.

Additional details: When I connect the dongle an “Ethernet” option comes up with many options available that I’m not familiar with. I called Sprint but they are not familiar with this. I did see the article about PPP authentication but unsure how to proceed.

This is what happens when I connect the dongle to the Chromebook with screenshots. A “Ethernet” option comes up:

Then if I click the “Configure” box option as seen here:, this pop-up opens:

Depending which EAP method I choose as seen here:, the following options are available:

I did see that OTG cables are able to connect USB dongles to smartphones but the Chromebook doesn’t have the mini usb ports. Perhaps there’s a way to use an OTG cable with a Chromebook?

Another thing to consider here:

If I switch off “Configure IP address automatically”, the status then said “Connected” and it was green, it has some IP address info, but still was not able to connect to the internet.

Came across a “PPP authentication” article from Google, is anyone familiar with this?

No “Use system certificates” when trying to connect to WiFi

I am having a problem connecting to my university Eduroam WiFi.

If I understand correctly, in CA certificate I am supposed to select CA certificate if it is there or Use system certificate and input my university domain.

But, I only have: Select certificate or Don't validate. And if I click Select certificate, nothing is changing, there is not a Domain field appearing like I think it should (and where I could the domain name) (see screenshot).

Can you help?

Moved AD Connect to a new server and now end-users are getting errors when replying to internal emails in Outlook

I moved my Microsoft AD Connect install from one server to another today. I installed AD Connect on the new server in staging mode, turned on staging mode on the old server, turned it off on the new server and let it run. All seemed fine, I checked back about 20 mins later in my Office 365 Admin portal and all objects were still in sync with AD, great.

However, about an hour later one of my users tries to forward or reply to an email to another internal user in Outlook and receives this message, name removed:

Your message to couldn’t be delivered.

I’ve since heard that 3 other users started getting this message since I made the change. Luckily it’s Friday and they’re out of the office now, but I can’t help but feel the two are related.

I didn’t save the config on the old server before I uninstalled it, but the one think I’ve noticed, when comparing it to other AD Connect installs that I have is that those ones default to Source Anchor: ObjectGUID. However, when I look at this one, the Source Anchor is: ms-DS-ConsistencyGuid. I opened a ticket with Microsoft and they assured me this wouldn’t be an issue, but it’s the only thing I can see different between the two.

We did an office 365 migration and made sure to port over the X500 records from the previous on-site Exchange server, that was several months ago and there’s been no issues.

Has anyone encountered anything like this? I did notice on the new AD Connect server, on the first Full Import to the Office 365 tenant it had about 150+ adds for new CNs, seems related.

Any input would be greatly appreciated.

Can you connect an output from a logic gate to 2 or more logic gates or inputs?

I have been given this diagram of a circuit:

The second XOR gate looks like its output is being connected as inputs of 2 different gates at the same time. Am I interpreting this incorrectly or is it possible to send the a single output to 2 gates simultaneously?

Connect Strongswan/VPN-Client (Debian) to IPSec/L2TP Server (Windows 2012) – AUTHENTIFICATION_FAILED

I am trying to connect my Debian Stretch box with a network running Windows-Only machines. There is a node there that acts as a VPN Server that runs Windows Server 2012R2. I am able to connect to it via L2TP VPN from both my Windows and my Mac machine, so even though I don’t like the setup – it seems to be working. It’s dumb easy configured without certs with a simple PSK. But all my many hours of trying to get it connected with a Debian box failed today 🙁 I have tried every possible config modifications I found on the web… Here is the shortest one I am trying now getting always the same error at the end (PSK is correct):
