Click to expand...
Click to collapse
if you are accessing internet you cannot access adb at same time you need to disconnect internet tethering to access device from adb
situation remains same
Well the situation is absolutely the same even after diabling tethering

Hi to all of you,
I bought the Vodafone Joy 845 for testing and development but when i connect that device to my linux box and run from the shell "adb devices", i can't see it.
The devices appears as a cd.
lsusb lists it as vid 12d1, pid 1031 usb_storage device emulating a cd.
What can i do?
Thanks in advance

Is USB debugging enabled? I had issues with Windows 7 and USB adb and now I just use adbWireless (app), that is more comfortable too.
Re
Yes debugging is enabled of course. I'll try your suggestion
install usb-modeswitch

The drivers for windows are inside the joy 845
Simply plug the device using the usb cable, open windows explorer and run setup.exe
(if setup.exe is not visible and u see the contents of the device instead unplug and plug it again. Yes i know it's strange)
After that run again the adb devices command. It may display the device with a questionmark but it's no problem, you can start deploying and debugging
good luck,
Anastasios
anastasie gia su did the fone have gps? and there is any way to install wm?
adb in LINUX
Hi Anastasie,
The problem is not with windows!
I'm talking about adb devices in LINUX.
Anyway
thanks

Hello all,
I have installed android sdk, google usb drivers etc. I am using windows Xp. My phone is upto date as per the Sony PC companion installed in windows. When I try to connect my phone in usb debugging mode to adb, its not showing up. when I give adb devices it doesn't list any devices.
when I give adb shell, it says device not found. I tried all methods like kill-server, start-server and killing adb.exe etc. after I went thru the existing threads in this forum. Nothing works !!
And the interesting thing that I could not figure out is about the device manager. After I try all methods it says drivers not installed. I try to install google usb drivers as well by browsing the folder in my android sdk . It was displaying like 'nothing found to install'
Any ideas please ??
One update.
Google usb drivers were not being installed correctly. When I update driver and browse to the Android SDK folder where the Google USB drivers present (My case .... Android SDK-> Extras-> Google -> usb_driver) it says 'nothing to update'
Then I edited android_winusb.inf file there and included my device ID (as showing up in Device manager). And it installed the drivers.
Then I opened adb again. And gave 'adb devices' and finally I could see my device listed !!!!
But still one major problem exists. That the device is getting disconnected continuously from adb and each time I would have to restart the adb and this makes it useless....
Not able to figure out why ...
Try using this: adbdriver . c o m
If it does not work try flashtool's drivers
THE DEVICE penta ws 708 c is detected in disk manager .even name and driver version displayed.
pdanet 3.02 installed and operating fine.when adb command is used in command prompt it runs fine.
but when adb devices command is run it shows under list of devices no name or number .
so also when backup command is run it says -adb unable to connect to the device. what needs to be done?
SDK IS UP TO DATE with ECLIPSE STARTING UP AND RUNNING AND PLATFORM TOOLS UPDATED> PLEASE CLICK ON ATTACHMENTS AND SEE IF YOU CN FIND ANY PROBLEMS THERE.
adb shows Unauthorized device on custom ROM for SM-231
I successfully rooted my SM-230NU and installed the custom ROM provided in this post
http://forum.xda-developers.com/tab-4/development/rom-android-5-0-lollipop-material-t3061873
However, when I connect the device using USB to my Mac and try "adb devices" I get "unauthorized" beside the device ID. I have already tried the following:
a. on the Mac: adb kill-server followed by adb start-server
b. on the Mac: Deleted the ~/.android/adbkey and ~/.android/adbkey.pub
c. on Device: Revoked the USB debugging access to all computers (on the device) and also via terminal emulator app verified that on the device /data/misc/adb/ directory is empty
d. on PC: Repeated all the above on a Windows 7 machine (still shows "unauthorized" beside the device ID)
e. Changed multiple cables and tried the same cable with other devices and they are all detected as valid devices.
Unless I get the device to be recognized I am not able to install some apks using adb install. Any help will be highly appreciated.
Just got a pixel 3a, it's running android 9. I want to unlock the bootloader. I'm following one of the popular root guides on this forum. I can't seem to get adb or fastboot to find my device.
Installed ADB applications from https://developer.android.com/studio/releases/platform-tools.html
Turned on developer options in phone, turned on USB debugging, plugged in phone.
Wasn't prompted for device authorization from phone.
Changed USB connection mode to PTP.
I have tried all USB connection modes, I verified the cable used to connect the pc to the pone is a data cable as I can transfer data when the phone usb mode is set to file transfer, ptp, or midiInstalled adb/phone device driver using https://developer.android.com/studio/run/win-usb
Still no debugging authorization prompt, but device manager lists the phone under 'Android Device' as 'Android Composite ADB Interface'.
'adb devices' doesn't list anything, tried 'adb kill-server', 'adb start-server', and 'adb usb'
'adb devices' doesn't list anything
reboot phone into fastboot by shutting down and holding power+volDown
'fastboot devices' doesn't list anything
Rebooted my pc, rebooted the phone, retried everything.
I'm at a loss, any suggestions?
Yea I've had some issues with adb/fastboot on windows as well. Sometimes it just won't detect the device, rebooting into my Linux install finds it instantly though. I haven't looked into how to fix it yet though as I can always just reboot to Linux. If you're on a version of windows that supports WSL, perhaps you should try that?
