Hello,
I am trying to activate the debug mode but it fails.
I go to Settings > Developer options > USB debugging.
I active the option, everything seems to work BUT
- still no device in adb devices
- if I go back to main settings and return to "developer options" menu, the USB debugging is disable again.
In the past, I succeeded to enable it by trying many times, unplugging and replugging the cables, with other options on and off and after many tries, it succeeded. Now that I had reset the phone (unlocked bootloader), I can no longer activate it.
Am I the only one? What am I missing?
Thanks
Install ADB drivers.

Hi.
I have ROMed i9305 (CM 10.1.3) and my PC doesn't seem to see it in MTP. No problems with PTP tho.
I'm using Windows 7 so I shouldn't have any problems. :c
I installed Samsung's drivers, nothing.
How can I fix it?

Ensure that USB debugging is enabled.
1. go to settings -> about phone then click repeatedly on the build number until development settings is unlocked
2. go to settings -> developer options (new menu) and then turn on android debugging (which mentioned usb in the description)
I've done a lot of googling so far, and I haven't seen anyone having this problem yet.
This phone is not yet rooted, and is still running the stock rom and recovery. I haven't been able to get to first base and unlock the bootloader with it because once I boot into Odin/download/fastboot mode, ADB can't see the device anymore.
Although I can turn USB debugging on and verify that ADB can see and list my device, if I reboot, and return to my Developer options menu, it will not still be checked. The problem, I believe, that's creating is that rebooting into Odin mode means that ADB can no longer see my device, because USB debugging has already been turned off. I don't think an app is doing this, because booting into safe mode, turning on USB debugging, and then rebooting into safemode again yields the same result: USB debugging has still been turned off. From the command prompt issuing "adb reboot fastboot" just yields a reboot back to the normal home screen.
EDIT: Upon further inquiry, do I even need USB debugging to get TWRP installed? According to:

they make no mention of USB debugging, only OEM Unlock which does not appear in the Developer Options for my phone...
Hello, I upgraded my nexus 6 using the factory image file 7.1.1 shamu-n6f26q-factory and everything is working fine. I got Developer Options visible so I can use the Nexus Root Toolkit by WugFresh like I always do and I cant get the pop-up where is says this PC allows ect or the "prompt for RSA fingerprint" as its called in the directions. I tried different USB ports and I tried selecting the different options and still no pop-up. Any Ideas?
OMG.... Please delete post! I have been messing with this for over an hour pluging and unpluging ect. and all it was is I turned debuging on but I didnt scroll down and tick the usb debuging on... Sorry guys its fixed!
I am on the stock, rooted rom. I just got the OTA. But I need to flash reflash the stock recovery since I am rooted and on TWRP. But I can't seem to get USB debugging to work. I've tried rebooting both my PC and my phone, different ports, tried enabling and disable USB debugging in developer options, even tried resetting to default settings. But adb devices still shows blank on my PC. Any idea what is the issue? I usually got a pop up to show that ADB is being requested and I will have to agree to it but I cant seem to get that popup now.

no matter what I do, my xz1c remains unauthorized whenever I attempt to connect via adb. I've scoured the internet and tried everything. has anyone had this issue with their xz1c and resolved it? I'd like to debloat my phone, but cannot because I cannot fully use adb. any ideas?

enable developer options - enable usb debug
1. Turn off usb debugging and developer options
2. Restart your phone
3. Turn on developer options and usb debugging
4. Plug in usb cable
5. Watch your phone screen carefully for an authorization dialog - and accept this. If you skip it, or cancel it by accident then you need repeat above steps.
6. ADB is now authorized.
I tried exactly this. Still "unauthorized".
Maybe current update of Android 9 blocks it.
