[FTC]: ZTE Phone is not detected on PC

[ArtemusMaximus]

We are finally at the point to start working with Android Studio, but I discovered we have serious problem. We have 2 ZTE Speed phones and both of them are not detected on my PC.
Here are troubleshooting steps I've done:
~ Tested my Moto G phone, it detects successfully
~ Check Device Manager - phone is not listed and no unknown devices present
~ Tried on different computer, still not detected
~ Tried different cables, still no luck

Not sure if it is related, but there are couple more nuances:
~ when connected to USB charger, phone, while charging, does not register that it is charging.
~ if I plug phones to charge while it is powered off it enters in Start up and Reboot loop.

Any ideas how to resolve these phone issues?
If we can't resolve this issue, is there a way to load custom programming via SD card?

Have you configured the phones per tutorials or videos:

Yes, I did. The problem is if you look in FTC Training Manual Figure 65 on page 44, I do not get N9130 , so I can't work on following steps.

I suspect that something is wrong with the phones as both of them are not detected as new USB devices in Windows

Did you do the "Install Driver" step; Fig 68?

Yes, but I am not getting prompted to install drivers

[DavisDad]

Do you see the ZTE in the Windows File Explorer?

When "Media Device(MTP)" is selected, our phone shows up as "9130". When "install driver" is selected, and I skip the driver install, I see two (2) items:

1. "Removable Disk (G: )"
2. "Removable Disk (K: )"

That is what I expected to see, as it happens with any other phone I have. I tried all modes "install driver", "MTP", "Camera" etc, nothing happens on the computer. You'd think: "OK, then phones USB must be bad", however, phones work with Robot Controller and Driver station. I can drive our push bot using K9TeleOp mode.

it is quite puzzling problem

I'm out of ideas... Good luck figuring it out. Let us know what you find.

A little update. Just received another ZTE Speed (ordered it from eBay). It works: detects, installs drivers, accepted "Hello World" app.

I will try ZTE Support, but not sure if they'll help me as ZTE Speed are not distributed in Canada.

I will definitely let let you guys know results.

Well, ZTE support is not much help for us, we can send phone for repair to them, but they can't send them back to us to Canada. So the only thing they are good for is a driver station

It's probably cheaper for us to get used ZTE's from eBay

[DavisDad]

If you'd like us to receive and send from the US, let me know. Amazon is listing the ZTEs for $40US with "free same day delivery". If you'd prefer new phones, I could buy and send to you.

Much appreciated the offer. I just received one I ordered from eBay (got a good deal = $20) and it works !!!!
If we will need more new phone I definitely will take you on your offer

I am still puzzled though why our phones are selectively not working
