I am having a problem with my MAXX where if i type in adb devices, i get no devices connected. Because of this, i cannot root this phone
(Yes, i have the drivers installed)
Can anyone help?
Stupid question but have you adb debugging enabled on the device?
did you restart the computer after installing drivers? i had the same problem and a restart fixed it for me
Is the usb debugging enabled?
If you are on win, is the driver properly installed?
Its better to have your phone in "charge only" mode while connected to the pc....
Hi, I have already had my USB debugging enabled and from my device manager I can see my device there showing "ASUS Android Devices" > "Asus Android Composite ADB Interface".
But when I reboot my tablet as USB mode and from my laptop I run cmd as Administrator, and run "adb devices" command, it just show me "List of devices attached" and then the command prompt.
I have already unlock and rooted my tablet.
Why I can't see my device id ? Please help
Try: Connect/disconnect device from USB. Kill adb server (adb.exe) from DeviceManager, and then run "adb devices" again. Also make sure that correct USB drivers are installed for your device.

Yeah this process is correct. Even I've experienced this.
What I did is:
Removed the USB cable connection and reconnect.
Kill adb.exe
Restart adb.
Then device was shown to be connected.

Yes, I did that but still the same. Any other suggestions?
If on windows make sure your driver's are installed.
Type in cmd
adb kill-server
adb start-server
If that doesn't work try a different usb slot. You could also try moving adb and it's dependencies to your system32 folder. It's where all your commands are stored for cmd. You won't have to navigate to the android sdk tools.

Have you enabled Debugging on in your phones Developer settings?

it's so easy, just turn off your android device, then hold down both "Volume Down" key and "Power" at the same time, wait a few seconds till it start in recovery mode, done.
now type adb devices, and you'll see your device.
no need for that.
close any adb process either from task manager or by typing: "adb kill-server" in adb console
close everything and use this customized adb file I attached, it'll show your device.
it also has instructions and necessary files for rooting your device.

In your case just disable USB debugging and then enable again.
fix the driver
I had this issue.
In my case when I went to device manager I could see the Device and wasn't installed correctly and could not load the drivers even after having installed them on the PC.
SO I clicked update drivers.
Select that will chose the drivers to install and select the Android Devices - ADB driver.
You will get a warning, but just ignore it and load the ADB driver for the phone.
Ensure you are in the sideload option of the recovery
Now
adb devices
it should show up as Sideload
Now sideload
Cheers

Just add ur device id in adb.ini
Same issue was faced by me on my micromax Q334 and xolo era, I search lot for that and finally just adding hardware id the device are detected under adb.The steps are clearly shown in my video below..
It will definitely going to sort this problem..
For that just right click on adb driver ,navigate to detail tab and search for hardware id then add to adb.INI

not work my friend, the list of devices is empty
Put your phone in PTP mode... just found this. When it was on charge or MTP nothing would connect, but when it was in PTP adb.exe said "error: device offline", but on phone it asked if I wanted to trust the computer!!! Ohhhkay, now we're getting somewhere. Clicked trust and ran adb devices and there it is
See below... I found there are two versions of adb.exe I was using. PTP is not the problem, but adb.exe has to be the right one or it just says offline.

ALSO!! Get the newest driver pack from LG "LGMobileDriver_WHQL_Ver_4.1.1". The driver packs in the roots that I downloaded aren't new enough. After Windows got the right drivers I was able to see the COM ports properly.
I'm not sure if I have the root working currently. The "Newest root method V03" where you click on root.bat seems to pick the wrong COM port. When I try to do it manually with Send_command.exe using the other COM port it seems like the root process doesn't work properly. It eventually completes, but no info about what it did etc.
I'm using an LG Transpyre VS810PP with Android 5.1.1 currently, and a Windows 10 64-bit machine.
Hello XDA-Developers,
I have a problem
I have an android phone Jelly Bean 4.1.2
I already installed the drivers of my phone to my computer, when i plugged the cable i enable USB DEBUGGING.
after that i checked device manager and my phone is listed under Android Phone
After that i go the console and type adb devices it starts the server and returns an empty list
i tried everything
i also try kill-server and start-server still the same
PLEASE HELP
then
Maybe try a different usb slot. One directly on the motherboard, it sometimes helps.
Hi:
I was having problems with my watch this morning that required me to reset it. After that I became a developer and turned on ADB debugging. I have some settings that I need abd to set, and so I tried to connect it. When I first connected it to my linux computer I got:
[[email protected] Gwatch]# adb devices
List of devices attached
04f7f0fe01a27d20 offline
Click to expand...
Click to collapse
I turn off and on adb, rebooted the watch, and moved it to another USB port. Now the watch open a card that says "Allow debugging? Open your companion device to allow debugging". I have no idea what to do with this. The computer still says that it is offline.
What do I do now?
The watch is running 5.0.2 and is rooted. The computer CentOS 7. This was working before I did the reset.
Alright, I've tried installing the drivers from Verizion and also using the drivers from the Android SDK and either way I have the same problem. ADB devices shows my phone, however whenever I try to push, pull, or reboot (the only commands I have any use for atm) the command prompt hangs like it's trying to access the device but no matter how long I leave it the device will not reboot, nor will any files appear in the correct folders on either the device or my computer.
I'm trying to root my phone and this is a pretty major roadblock.
Note:
USB Debugging enabled
ADB drivers installed
Phone shows up on "adb devices"
There is no error or any other output in the console. The best way to describe this problem is that ADB hangs.
I'm running Windows 8.1 and my phone is running Android 4.1.2
Also, I don't know if this is normal but, In order to get the notification that "USB debugging connecting" I have to use the internet connection option on the phone. When using MTP, Charge only and PTP that message doesn't appear and I don't see an ADB device show up in device man.
Things I've Tried
Uninstalling all Android drivers and redownloading/installing them after restart
Restarting my phone multiple times
Running adb kill-server / adb start-server
Changing USB ports7
Thanks!
Try installing drivers from LG. This seems the right one but double check:
