Can't access phone through ADB

I am trying to access my phone through ADB to register w/o data. My device center and device manager both see the phone ("Android Phone" in DC, and "ADB Interface > HTC Dream" in DM). However, when I run ADB from the command line it cannot find my device. I have tried reinstalling drivers, killing and starting the ADB server, and even re-flashing my phone.
Note: When booting the phone from a fresh flash I DON'T have to enter "<enter>setprop persist.service.adb.enable 1<enter>" to initialize ADB. It is automatically seen as an ADB device, and after entering the command it is only seen as a storage device.
Thanks in advance.
(unlocking a Dream on Windows 7 x64)

Solved it by installing the drivers from here: http://www.mydigitallife.info/2009/08/24/workaround-for-htc-hero-sync-problem-in-windows-7/

G2 don't recognized by ADB

I saw on internet that I can do screen recording from phone, but i need to run a command via adb, and adb doesn't recognize my LG G2(D802)..i had installed the correct usb driver from lg site
When i open ADB and type: adb devices, it says "List of devices attached" and no name of device appears
PS: developer mode is enabled
EDIT: i managed with that..but now says that the device is offline what means that?

no fastboot or adb access

I can't access my N7 with adb (when booted) or fastboot (while in the bootloader). It's connected via a USB cable. This is both with a Mac and WUGS. Commands like fastboot devices or adb devices return nothing as the device isn't seen. I can connect my N4 and use those commands without problem. I just tried doing the same with my 2013 N7 and it's not being seen, either. Strange. I don't think I've had this problem before on the Mac. I have on Windows, which I can sometimes resolve by installing and reinstalling drivers until something works.
I'd wanted to update the 2012 N7 to Lollipop.
Thoughts, anyone?

Crazy as it sounds, try another USB cable. Reboot everything, plug in fresh, and try again. Failing that, use WUGS to reinstall all your USB drivers. Use the stock Google.

The cable was the culprit. I tried another and it worked. Thanks so much!

I'm having a similar problem that's driving me insane.
Nexus 7 wi-fi version
I've loaded every driver on the planet and in recovery mode it simply will not show up. And I'm not talking won't show up using ADB, I get absolutely nothing in device manager. So before anyone tells me to point to the device and manually change the driver, there is no device to try and point a driver to.
In "normal" mode, it shows up perfectly fine in Device Manager as Android ADB Composite Device. ADB will list it in devices with no problem. It will accept the "adv reboot recovery" command perfectly and reboot the tablet into stock recovery. The minute it does that, the device disappears from the Device Manager list and nothing takes it's place. I've tried to have it search for new hardware, I've tried the Google USB drivers kit, I've used Koush's Universal Driver install. I've used 3 different cables on 2 different USB ports.
This is a completely stock N7 running 4.4.4 plugged into a Windows 8.1 64 bit PC.
The last thing I'm wondering is do I have to unlock the bootloader at all? I don't want to because it'll wipe the tablet. If so I guess I'll just wait out the actual OTA rather than try to sideload it.
Any suggestions would be appreciated.

Ummm... does the Stock Recovery actually run "adbd" by default? If it doesn't (or it doesn't start adbd until you execute the sideload menu item), then you wouldn't normally see anything on the other side of the cable with a stock Recovery. (I don't have my tablet with me to check)
Here's an extra "any suggestion at all":
Get rid of Windows and use Linux; there are no drivers to screw with in the latter case.
No, seriously. But probably not what you are thinking.
If you can get a "live CD" to boot** on your PC, you can (as root) run the "lsusb" command to see what devices are enumerated on the USB bus, port by port.
In conjuction with the decoder ring at the end of this post, you can determine from inspection of the USB VID/PID identifiers whether or not all the hardware is behaving, and whether or not the tablet is in the mode you think it is supposed to be in.
The reason this is valuable is that it allows you to take drivers completely off the table; if everything is as it should be, then you know that all the hardware and cabling are functioning correctly, the tablet is behaving correctly, your PC hardware is behaving correctly, and that 100% of the problem is Windows driver issues.
If you want to go the extra 1/4 mile, you can put a copy of (Linux) fastboot & adb plus your flashables on a USB key, and run adb or fastboot from the Live CD boot. It won't matter that the live CD doesn't have them preinstalled, they will be on your USB key. It will be easier on you if you can find statically-linked fastboot and adb binaries; if not you will have to copy one or two supporting shared libs (.so files) along with the binaries, and find out what LD_LIBRARY_PATH is all about.
suppose the USB key mounts at /media/usb1; then
$ sudo /bin/bash
# mkdir /tmp/tools
# cp /media/usb1/fastboot /media/usb1/adb /media/usb1/*.so /tmp/tools/
# chmod 755 /tmp/tools/*
# export LD_LIBRARY_PATH='/lib:/usr/lib:/tmp/tools:.'
# cd /tmp/tools
# ./fastboot devices
OR
# ./adb devices
Good luck; as you are using Windows you are going to need it. Hahaha LOL
**depending on whether your BIOS on your win 8.x PC can be toggled between UEFI and Legacy modes or not, this can be either trivial (Legacy boot mode) or complicated (UEFI) requiring a "Trusted Computing" crypto boot shim from MisterSoftie.

Ok this works for me
Use USBDeview (http://www.nirsoft.net/utils/usb_devices_view.html)
delete all the associated drivers like Google, Samsung, etc for ADB, etc
Restart Computer
Reconnect N7 without MTP and USB debugging
Wait for PC to recognise device and install driver
*If you see something like PC unable to recognise device, go into device and Update Driver and choose "Automatic....."
Disconnect and Reconnect with MTP and USB Debugging
Wait for PC to recognise device and install driver
Restart N7 in bootloader
Wait for PC to recognise device and install driver
Profit
* My PC OS is Win 8.1 Pro 64bit

make sure mtp is switched off, i couldnt get adb or fastboot on my nexus just now . switched off mtp and works fine

[Q] Working with ADB & Fastboot

Has anyone gotten this to work? When I type ADB devices, I get:
Code:
????????? no permissions
I rebooted into fastboot with no luck either. Except now ADB doesn't even pick up any devices. And yes, I enabled USB debug mode and unauthorized sources.
Thanks!

I'd guess you are using an older version of the toolkit. Try downloading the latest SDK and using it to see if that helps (it'll also update to the latest drivers). Good luck.

Linux - Ubuntu to be more specific.
So I figured out the issue. I rebooted into the bootloader (unplug NP, plug it back in, immediately hold the button located on the bottom of the player until the light flashes), typed fastboot devices and it finally recognized the device. ADB still however did not recognize the device while in the bootloader until I powered it back on. Very strange... Not sure if the order I did things made a difference but I'm able to connect to the interface now.
Hope this helps someone. Cheers!

I had the same issue on Ubuntu. You need to run ADB with sudo...why? I have no idea...but I found a post suggesting it on StackOverflow and it worked...so I'm not questioning it.
Before doing anything below, have you installed adb via apt-get? If so, remove it and just put a link to your SDK manager adb and fastboot in a folder included in your PATH or add the directory to the path, then start a new shell before proceeding. The adb and fastboot provided by apt-get are old.
Do the following:
Have your device plugged in and fully booted and with USB debugging enabled
run this command: "sudo adb kill-server && adb start-server"
You should be prompted on the device to authorize the access of your computer via adb
run "adb devices" to make sure that it all worked correctly

Driver installer does not start/ no device in fastboot and ADB

When I start the setup file from the Nokia drivers I get an adminstrator prompt and thats it. When I go to downloading mode the device is listed as ADB in device manager but is not listed when I enter ADB devices. USB debugging is active.
Any ideas where to get working Nokia 6.1 plus ADB driver? I am on Windows 10.

Minimal ADB drivers do not work with this device. You need to download Google's ADB from their website.
