adHow to fix ‘ADB Device is listed as offline’ on android 4.2.2?
NOTE:
New security enhancements in android 4.2.2 builds require the end user to explicitly grant adb access to any connecting computers before that connecting machine can successfully issue any adb commands to your device. When you connect a 4.2.2 android device to your machine (with USB debugging enabled) for the first time, you should be prompted with a confirmation message to allow or disallow USB debugging. This message will display your computers unique RSA key fingerprint and provide you a checkbox to “Always allow from this computer”. Check this box and select ‘OK’. Your device should no longer be listed as ‘offline’:
** TIPS**
Note: dashes " - " in command line CMD PATH MUST BE THE SAME.... of the Andriod SDK Tools .
Note: update ANDRIOD 4.2.2 ( api17 ) SDK MANAGER TOOLS
Run on win7 64 bit os
USB 2 iNFUSE 4G rooted ROM 4.2.2 J.B.
*** try this ***
If you don’t see this prompt then you should try the following:
•With your device connected via usb and the toolkit running, toggle USB debugging off/on in Settings > ‘Developer Options’ and see if the prompt comes up.
•Also try unplugging and re-plugging the usb connection.

I installed sdk android-sdk_r07-windows.zip and also tried with android-sdk_r06-windows.zip.
When I do "adb devices" the list of connected devices is empty. My phone is a Huawei U8230.
The USB debugging mode is enabled. I can also see the files inside the phone in a Windows Disk Drive.
Any sugestion on how to get the device listed?
A bit stupid... But your phone is running android ?
You can try to search your phone drivers if there were somes, didn't it ?
Fixed it.
1. First Installed the SDK (all components including usb drivers).
2. Then Enable USB debug mode on the phone.
3. Then connect the phone.
4. Then a CD Drive is detected -> run setup from that drive.
5. Last restart adb.
Fiuuuuuuuu that costed a lot!!!!!!
Do You Like To Flash Custom Stuffs On Your Android phone? Or Are You A Developer? But You Can't Able To Do It Because You're Facing Some Problems with Your Adb & fastboot. All Of This Problems Are Only Because Of One Thing And That is Drivers.
And If you agree With Anyone Of This Situations Then You're At The Right Place Because Today I Am Going To Tell You That How You Can Install The Adb Drivers For Your Specific Android Phone On Your Pc.
Adb drivers are necessary if you want to flash a android device through Fastboot mode or if you're a android developer. Usually Our PC installs the adb drivers automatically for the specific android device but sometimes it can't so you have to install it manually.
This will also help you to solve adb errors like Device is offline, USB debugging Authorize pop-up not showing in android And etc adb errors. Make sure that your USB debugging option in developer mode is enabled on your Android device Because without this you can't use adb.
Steps:-
*So first go http://adbdriver.com to and download the "adb driver installer (Universal)". Then extract it.
*Now connect your Android phone to your PC using USB cable. Then Open the application.
*Now you will see something like Adb interface drive and with a red Cross at left side. Make sure to refresh if driver option is not shown.
*Now Just Click On install To install your device adb drivers. Then it will Install the adb drivers for your specific android phone in just under 2 minutes.
*Then Allow The USB debugging On your Android phone. Then the adb drivers will get successfully installed.
*If still adb can't recognize your device then try to connect your phone in PTP Mode instead of MTP or Charging only modes.
*If still it doesn't work for you then Revoke USB debugging Authorizations in developer mode. So that's how you can install the adb drivers for your Android Phone.

As the title says.
I'm trying to unlock the bootloader on my XZs so I can root it.
My device is listed normally when turned on w/ the command window, but in fastboot mode it disappears and when I try a command, an error comes up saying ""error: no device/emulator found". (see attached image)
As far as I'm concerned, I have all the necessary drivers, I've tried on another PC, the result is always the same.
And when I try to change the drivers (Via Device Manager>Update Driver>Browse My Computer...>Let me pick...>Have Disk...)
I get yet another error saying "The folder you specified doesn't contain a compatible software driver for your device..."
Can someone please give me a solution. This has been asked before on XDA by someone else (that thread has no replies). It seems it's always us little guys with actual problems which need solving who get little to no help at all here.
Reinstall driver again.
It doesn't work. The problem is I want to install the Google USB drivers for my Xperia phone but Windows 10 will not let me and driver signing seems to be impossible to disable (currently typing this on my laptop while it's in test mode).
1. Turn off your phone. Boot in to fastboot mode and plug the cable. After your heard the sound from the computer for new device found. Go to device manager look to usb S1 device. Reinstall driver by manual choose (do not search) from the menu with the name is Android Google. When prompt for install. Choose install anyway. After successful install driver, please check status from flashtool to make sure your device show connected in fastboot.
2. Change the usb port. Sometimes you get problem with usb port 2.0 and 3.0
Hope you can fix it asap.
Nothing by the name of 'Android Google' appears in the menu when selecting new drivers.
I clicked on 'S1boot Fastboot' under 'other devices' in Device Manager and clicked on update driver
>Browse Computer
>Let me pick
- and then there's something similar called 'Android Device' but no 'Android Google' so I click on that
- then I get three options:
Android ADB Interface Version 11.0.0.0
Android Bootloader Interface Version 11.0.0.0
Android Composite ADB Interface Version 11.0.0.0
None of them worked when I tried.
I think the solution is to have the phone on, with USB debugging enabled, connect via USB to PC, test your adb devices again, if all good, go ahead and
Rich (BB code):
adb reboot fastboot
This is because some phones use Fastbootd (notice the d..).
I have completely install android studio but it could not establish connection with real device mobile.
It shows me no device.Already,i set developer mode but it not works.
Please help?
On windows: install adb drivers for your device
On Linux: add usb device to udev (you can check connected devices using lsusb command) or run as root (not recommended but you could try if that works, then fix udev)
I'm trying to root my newly update U11 Pie. Got ADB up and working and developer options enabled. However:
Code:
c:\HTCU11>adb devices
List of devices attached
FA77R180xxxx unauthorized
I am never prompted on the phone to authorise USB debugging. I do get a prompt to "Use USB for file transfers", every time I connect via USB. I've set default USB configuration to be "No data transfer" and I've repeatedly hit "Revoke USB debugging authorisations".
Any idea how I can authorize my PC for debugging?
Ah, just me being a dumbass. I've since downloaded the latest SDK Platform Tools and the phone is now prompting me to authorize:

TWRP and Magisk installed, all is well again with the world!
