Flashing the latest stable CM build on 1st gen Moto G (currently on 5.0.2)

Hello everyone.

I rooted my Moto G a while back to install a specific app.

Now I want to flash the latest stable CM build on it (based on Kitkat 4.4.4) but it seems like the phone isn't detected in the terminal.

All I get is "error: device '(null)' not found".

Any help?

TIA

Digging in ... do any head units currently support these items?

I'm (hopefully tomorrow) replacing my dying Jeep. Likely candidates are a 2014 Rav4 or a 2012 Town and Country. Both seem to have good double-din slots without having a lot of vehicle subsystems tied to the factory HU. So ... I am beginning to investigate putting in an Android HU.

I'd like a recommendation on the best HU -for me- ... I know it isn't going to be the same for everyone. What I'm looking for, in no particular order, and not all of these are must-haves:

* community-supported ROMs

* 2GB RAM is highly desired.

* video input for the factory-equipped backup camera

* steering wheel controls (I'm assuming I need an adapter specific for whichever car I buy, probably not included with the HU but I want the HU to be able to accept them if possible)

* Decent sound quality output

* Good radio reception (does the US have an equivalent to DAB?) ... I'm willing to use an external FM module if that ends up being the highest quality option. App support is included in the word "good" here. And as likely figured out, I'm in the U.S.

* Some SIMPLE form of external storage (SD card is fine, USB HD is fine, I even have a spare 60GB SSD with built-in USB port since I just rebuilt my PC)

* Ability to tether to my WiFi hotspot (currently it would be a Nexus 5 phone) OR Bluetooth data connection (but I've found BT data sharing to be less well supported).

* Lollipop? I realize from searching there aren't any out there yet (pfft @ Parrot for nixing the aftermarket version of the RNB6) ... I'm not in a big rush to do the upgrade RIGHT NOW, if I can wait a few months to get a 5.x HU I will do that. Just need to know if such a model is known to be in the works?

I might go with a tablet-in-dash alternative, but would rather have a full HU. I've looked at various applink/mirrorlink solutions and found them all wanting.

Most stable and feature such ROMs currently?

My wife has a sm-t320. Currently running a nightly CM build from February. Tried to download and install recent nightly but play services kept force closings so i restored a backup. I don't have time to research, install and check various ROMs mostly because she hates when I do it but I was given permission because WiFi keeps dropping but only on her device.

Suggestions would be helpful.

Thanks!
