ADB not working - what am I doing wrong?

[anwul62]

I'd like to remove some bloatware from my Samsung S10 (Android v11, UI 3.1), specifically the LED cover software as it conflicts with Bluetooth devices when closing the lid (loosing connections each time).

These are my exact steps
1. download https://dl.google.com/android/repository/platform-tools-latest-windows.zip
2. Extract zip file
3. copy folder "platform-tools" to C:\ADB
4. On smartphone, change to developer mode:
Settings > About Phone > Software Information >tap Build number 7x
5. Connect the smartphone using USB

Change USB mode to "File Transfer mode", as follows:

6. Smartphone: Settings > Developer options (at the bottom)
7. Tap on: "Default USB Configuration", select: "Transferring Files"

8. Windows (command prompt) go to C:\ADB
9. (Admin) Command prompt: adb devices

C:\adb>adb devices
* daemon not running; starting now at tcp:1234
* daemon started successfully
.List of devices attached

-nothing listed-

10. Download and install latest Samsung USB Drivers
go to site: https://samsungusbdrivers.me/
download : Samsung-USB-Driver-v1.7.43.0.zip (may 10, 2021)

at install I get a warning:
"Samsung USB Driverfor Mobile Phones is already installed on
your computer. Do you want to proceed with the installation anyway?"
Clicked [No]

11.In Windows 10 Device Manager - S10 is listed and 'working properly' (properties)
I can access the S10 from within Windows
Like: "This PC\MyName's S10\Phone\DCIM\Camera" and files are being displayed there.

Any suggestions?

Thanks!

You don't say anything about enabling USB debugging (ADB = Android Debug Bridge, and requires USB debugging to be enabled).

Step 4 enabled the "developer options" menu. Find that menu (in regular Android 10 it's in Settings > System > Advanced, but as Samsung rearrange the menus it's possible it will be elsewhere for you), and in there you can enable USB debugging. Then try again.

Many thanks!
Indeed, this was not enabled. Overlooked this.
Enabled it and got this "Allow USB debugging?" (with RSA key).
Now, indeed "adb devices -l" shows :
RF8XC0QDR3P device product:beyond1lteeea model:SM_G973F device:beyond1 transport_id:1

Again, thanks a lot!

I believe it worked out well.

FWIW - updated 'steps'

Removing bloatware from Samsung Galaxy S10
Android v11, UI 3.1

1. download https://dl.google.com/android/repository/platform-tools-latest-windows.zip
2. Extract
3. (I did it, but it is optionally) copy sub folder "platform-tools" to C:\ADB
4. On smartphone, change to developer mode:
a.Settings > About Phone > Software Information >tap 'Build number' 7x
b.Settings > Developer Options (at the bottom) > USB Debugging: enable
c.Click OK
d.In the next screen (optionally select "Always allow from this computer") plus "Allow"

5. Connect the smartphone using USB

Change USB mode to "File Transfer mode":

6. Smartphone: Settings > Developer options (at the bottom)
7. Tap on: "Default USB Configuration", select: "Transferring Files"

8. Windows (command prompt) go to C:\ADB (or to 'platform-tools')
9. Enter: adb devices -l

it should show that device is connected, like:

C:\adb>adb devices -l
List of devices attached
RF8MC0QDR2P device product:beyond1lteeea model:SM_G973F device:beyond1 transport_id:1

10. Collect a list of all installed software
Enter: c:\adb>adb shell pm list packages

11. selectively remove software (in this example "LED cover software")
package:com.samsung.android.app.ledbackcover
package:com.sec.android.cover.ledcover
(remove the word 'package:' in the uninstall command)

C:\adb>adb shell
beyond1:/ $ pm uninstall --user 0 com.samsung.android.app.ledbackcover
Success
beyond1:/ $ pm uninstall --user 0 com.sec.android.cover.ledcover
Success
beyond1:/ $ exit

c:\adb
