[Q] USB debugging not turning on - LG Optimus 4X HD

I cant seem to turn USB debugging on, that prevents me from rooting and installing a Recovery, very annoying, any way of fixing that ?

Is your trouble on the phone or on PC? you don't need to have USB debugging to be on for Rooting.
Was your USB cable plugged in while trying to turn it on?? USB debugging can't be toggled with USB plugged.

I tried both unplugged and plugged. When I was trying to assign a custom app for debugging it wont list anything. Kinda fixed it by running a separate USB Debugging app with busybox.
Was trying to unlock the bootloader.
One more thing, I've been waiting for like 5 minutes now for the bootloader to unlock, it gives me a "Running factory reset for the first Bootloader Unlock :lease Wait::" is that normal ?

Computer won't activate phone in USB Debugging

So I am trying to unlock this Captivate and I Enabled the USB Debugging option when it's plugged into the computer. Problem is, when I actually connect it to the computer, the device doesn't go into USB debugging mode. Any help on this would be appreciated!

has anyone came up with a solution?

Which method of root did you use? Do you have developer options debugging enabled?

I used this guide: http://forum.xda-developers.com/showthread.php?t=2603358
Yes I do have the usb debugging enabled....
I have already disabled, enabled and nothing....
The only way the phone and the pc detects the usb connection is when I restart the phone in bootloader and then do a normal boot.

I've had similar issues a few times and from my end, it seemed to be some kind of quirky driver bug. This might seem so simple it's ridiculous, but the few times it's happened to me, unplugging the device and rebooting both the PC and phone before plugging back in worked. Worth a shot?
Yeah, that works but I don´t want to reboot the phone every time I need to plug it in.
Since I use the Mobizen app to use my phone from the PC at work, I plug in and out about 4 times a day....

mobizen can be ran wirelessly. why do you need to plug it in exactly?

Cause you have to be in the same network to connect it wirelessly and the wifi at work is not in the same network as my PC

well i wish i could help but i have an unlocked phone so im not sure what your problem is. if rebooting the phone works then it is clearly the phone. you can try to kill the adb server connection in cmd and see if that works.
Code:
adb kill-server

I appreciate your help!
Problem is that the phone only charges when connected by the usb port, so the debugging isn't enabled by the phone and there is no adb connection to kill.

oh, i just assumed since you can start the server on your computer without the phone plugged in and the server stays running even after unplugging the phone that you might could try killing it before plugging the phone back in (assuming you have ran adb commands on that computer and it hasn't rebooted since). But that was just a guess.

Hey..
Could you please elaborate your issue a bit? Have you enabled USB debugging? What happens when you run adb devices on your computer?

Check any antivirus is not blocking anything
Please run a command window from adb and run this

Installed CM13 and getting BSOD when connected to PC

Hello everyone,
Yesterday I installed CM13 and it is very good. I haven't found any problem as of now in my phone but I am getting BSOD everytime when I connect the mobile to my PC through USB. I tried everything from changing the cord to changing the usb port, even uninstalled LG drivers but still getting BSOD.
Can anyone help me to understand and solve this. Right now my only option is to take SD card out and connect it using Card Reader. Phone is working smoothly. No issues so far. Its just this problem is bugging me. Appreciate if you guys can help me out. Thank You.
Okay so I am getting BSOD only when I am enabling the USB Debugging. By disabling USB Debugging I am able to connect the phone to PC but it is only in the charging mode. I am not able to access any files. It is showing blank. So what should I do now?

1st: The USB Debugging problem only occurs on Windows, Linux distros are fine
2nd:Just pull out the status bar and click on the charging one. You'll be given 3 options: charging, MTP and PTP. (Sorry if I misspelled the names, it's been a long time since I've done this)

Thank You. I can now access the files.
Yes I am on Windows 10. USB Debugging BSOD is still an issue. So is it okay to keep USB debugging off? I always keep that option enabled cause I thought its an important option if you happen to brick the device. So what is the solution? is this happening for everyone who are on custom rom?
Thanks once again.

It's okay to leave it off. If you happen to brick your device, it won't boot, meaning no USB debugging.

Someone post answer in cm13 thread - some issues with drivers from LG with cm roms compilations or something like that. Just UNINSTAL driver from PC and u good to go connect l90 via MTP
You mast UNINSTALL driver from PC and reboot PC.
Then install this drivers and reboot PC:

Go to the the developer options and turn on "Always prompt when connecting to USB" . Should work.
