ADB won't detect my tablet.

USB debugging is enabled
OEM Unlock is enabled
Device gets detected by my computer, allows me to transfer files using MTP and whatnot
Open command prompt in the platform-tools folder using the shift+rick click command to open it in the directory
type in adb devices, get no results.

Thanks in advance for any help

Nope, didn't do anything.

Also, I don't get any message on my tablet asking me to authorize the adb connection. ADB is not reading the device. I'm sure that there's something small that I'm missing here, any yhelp would be appreciated.

Edit: Still working on this, it seems that my computer isn't detecting the ADB drivers. I should have them already installed, I use adb on my M8 all the time. Is there a way to manually install ADB drivers, or is it just the USB driver for the device?

Edit 2: Just plugged my M8 in, adb is able to detect it right away.

I had the same problem.
This worked for me ^^

ADB Devices empty?
This is to help those of you folks that are running into an issue with your ADB Devices command returning blank.
This is assuming you have gone through the trouble of troubleshooting and researching yourself. If you are at this point and reading this post, then you most likely already tried stuff like a different USB port, cable, adb kill-server / start-server stuff, and ensuring you have USB debugging enabled.

If you are still stuck, then let's get to work.
Windows 8/7
1) Plug the device into a USB directly connected to MOBO or into your mobo. If you are prompted with some ping on your computer, then that is a good start.
2) Open -> Device Manager
3) Go to "Other Devices"
4) Identify the tablet. It will probably say "ADB USB blah blah". That's the one we want.
5) Right click, Update Driver Software
6) Browse my computer
7) Let me pick from a list of device drivers (bottom box)
8) In the pop up select, "SHOW ALL DEVICES" at top of list, click NEXT.
9) Click "Have Disk"
10) Browse to your path where you have:::: "android-sdk\extras\google\usb_driver"
11) Click okay
12) Select Android ADB Interface
13) Click yes -> Install -> Close

At that point you should have your tablet asking for permission. If it's not plugged in, plug it in and see the prompt.

Enjoy

Can I root LRX21Q with the files listed in the first post? I couldn't wait for the OTA so I flashed the files. Want to get my root back now.

Thanks
Most likely it'll work. Try it and let the rest of us know. Everyone is downloading 5.0 right now so it's real show our I'd try it
