ADB/USB Debugging Problem? - Samsung Galaxy S7 Edge Questions and Answers

OK, this is driving me nuts! The phone has been restored to stock (Android Version 8.0.0) and has nothing on it from the Play Store, just the stock Samsung apps - trying to get ADB to work without any joy, as want Fluid NG on it........
It did once offer the options (weird?), but I got the Allow USB Debugging popup with the RSA Key, but also the error 'Because an app is obscuring a permission request, Settings can't verify your response' error - Went to the 'Apps that can appear on top' section (assume this is the same as 'Draw over other apps?), and disabled everything in the list - still the same error!
Now the only options I get when connecting are:
Transfer Files
Transfer Images
MIDI Device
Charge this Phone
So far I've.......
Enabled Dev mode
Enabled USB debugging
Disabled Verify Apps via USB
Installed Samsung Drivers
Installed ADB Fastboot
Disabled all 'Draw over other apps' apps in the Apps list.
Tried another laptop
Tried another USB cable
It shouldn't be this difficult, I know!!

[Q] HTC Hero - No USB connection, but power, no other computer works

Hi Guys,
i have connected my Hero with different cables with different computers on different driver versions. It charges battery, but there is no USB conncetion. Yesterday it still worked. I think that this is maybe more a hardware fault as a software fault. ATM i don't have a microSD Card Reader so backup my data and USB Mounting doesn't work anymore.
I use FroydVillain 1.5 and i don't want to try to factory set, because on the last restores i just could restore per usb and not per recovery console.
Does anybody know about this problem or has a good idea?
After i switched off the phone and connected, my device manager on windows tells me unknown device and says an error code that device reported an errors and deactivated 'cause of that.

Install HTC Sync
Hi tried this already with 3 different versions of HTC Sync
Uninstall HTC Sync, use USBDeview to remove the usb drivers for your phone.
Restart
Check the drivers are removed with USBDeview again
Install the latest version of HTC Sync from HTC's website
Restart
Plug your phone in
N.B. If you're using a custom rom make sure you have "Unknown Sources" checked in your application settings & "USB Debugging" checked in Development settings. These settings might help though I think the second one is for adb access and the first is for installing apps from apk files. Worth a shot though.

Note 4 locked without USB debugging enabied (fngerprnt / bckup pword not recognised)

Hi
I have a Galaxy Note 4 (SM-N910G) and don’t normally muck around with the system. I have limited experience with Android.
My phone is locked (with important data stored in it)– a couple of days ago (presumably after a system upgrade) it suddenly would not recognise my fingerprint nor backup password.
I tried unlocking the phone using Android Device Manager but although I could get my phone to ring or display text, I could not change the password after locking the phone.
I called Google who said that Android Device Manager only works on earlier Android Versions - ?4 and below and most likely my phone would be running Marshmellow.
I called Samsung who said my only option is to restore to factory settings.
I wanted to use ADB
(to enter: adb shell
cd data/system
su
rm *.key) and downloaded it and tried to use it from the c:\ prompt but I don’t have USB debugging enabled. No device was recognised when running ADB.
I had not registered for a Samsung account so I could not use Find My Mobile.
I tried to apply an update via external storage in recovery mode (I downloaded files such as Lockscreen_Security_bypassV1.1.zip or Pattern-Password-disable.zip) but unfortunately when I tried to apply them, it came up with E:footer is wrong, E: signature verification is required.
(I also tried “Android Multi Tools”).
I do not have CMN recovery loaded nor Aroma+File+Manager
My question is: should I try and use Odin (have downloaded odin3_v3.11.2.zip) and TWRP to try and enable USB debugging or try to disable footer/signature verification??
Any other suggestions to try and unlock my phone???
At the minimum this has been an education!
Thank you for your help!

USB Debugging

My nokia 6 (1025) recently was updated to Oreo. Now, when I go to sideload an app, my computer does not recognize the nokia. I have developer options set up and usb debugging is turned on. Any thoughts?
Why you've chosen the sideload, you can simply use many other apps, which uses adb to install it directly on your device without shutting down to sideload mode, you can simply install it through some applications like mobeginie for desktop etc

The popup to allow usb debugging from my computer doesn't popup when I connect my phn

The popup to allow USB debugging from my computer doesn't popup when I connect my Oneplus 5 to my computer, and thus ADB devices comes back empty. This is only happening for my PC on stock Rom. When I tried installing another Rom, the popup to allow USB debug option comes and the phone is getting detected in my PC. Even on stock Rom, in another PC popup to allow usb debug option comes, only in my PC stock Rom it is not getting detected. Not sure whats and wheres the issue(PC or Phone)?!
I I've rooted my phone before and it was working fine previously and it stopped being detect after OB10 . I looked online too and tried options like restarting, turning debugging off and on, revoke USB authorization etc...... nothing works Please HELP!!!!

If you have a folder named '.android' in your User Directory, delete it and then try again. If this doesn't work uninstall your current ADB software and reinstall the Platform Tools package:
https://developer.android.com/studio/releases/platform-tools
I've had this once or twice and that always did the job.

On the Stock ROM, where you are having the trouble, does your PC see the phone when you connect it. i.e does it show up as a device in Explorer and Device Manager? When you enable MTP can you transfer files?
As it's only a problem on the OOS ROM, i wonder if it's a Driver issue. When you installed the Platform Tools, did you install the Google USB Drivers?
Also have a look here. There may be some useful information:
https://stackoverflow.com/search?q=adb+doesn't+see+my+device+on+pc
try to use a different cable. it works for me
i had a same problem like you
had the same problem on my phone (manually added the adb public key to get access), only got fixed by factory reset. the popup just didnt show no matter what, even though adb worked.

Transfer files fails

I haven't been able to get data transfer to work when connected to computer since Color OS 6 update. Pop up warning says resetting USB Debugging is required. Actions already taken :
1. Turn usb debugging on/off
2. Turn developer options on/off
3. Revoke usb debugging (adb devices shows device ID)
4. Enable usb tethering
Any suggestions?
After days of no response and some efforts of painful google-searching , I finally find a solution using adb command which is
adb shell svc usb setfunctions mtp
That being said there should not be any issue with usb / adb driver whatsoever, because I can use file transfer on my LG V30+ just fine using the very same laptop. Also system security check showed usb transfer is being blocked (see attached pics)
