USB Debugging option greyed out

Question

I have an LG-E405 phone running Android 2.3.6.

I connected my phone with a USB cable and selected the mode as Charge Only.

Now when I try to turn on USB Debugging, I find that that the option is greyed out.

So, how can I enable USB debugging in this case.

Answer 1

I have a feeling that if you have a corporate phone, your corporation IT might also be blocking USB Debugging. I've tried all the different connection modes and the USB Debugging option remains firmly greyed out.

I'm trying to get in to enable the BATTERY_STATS for GSam Monitor Pro, but I think it's disable through the Airwatch MDM software my company makes me use. They pay for it so I guess I'm stuck.

How to Enable USB Debugging for LG Optimus (LGD415). Android version 4.4.2 (KitKat)
Go to this website and download the drivers to your phone:
http://www.lg.com/us/support/mobile-support
For example, mine would be:
http://www.lg.com/us/support-mobile/lg-LGD415RD. Then click on “Software Update & Drivers”

On your phone, you need to enable USB debugging. To do so,
Go to “Settings”.
Go to “About Phone”
Go to “Software Information”
Tap “Build number” five times.
A pop-up will appear saying “You are now a developer”. Your’re not done yet.

Go back to your phone’s home page by pushing the home button.
Go to “Settings”.
Go to “Developer options”
Click the “USB debugging- Turn on debug mode when USB is connected”. A blue checkmark will appear.

(EDIT: If USB Debugging is greyed out, unplug your phone. USB Debugging should no longer be greyed out. If it is not greyed out, check the box and plug your phone into your PC.)

Unplug your phone from your PC. Then plug it back in. On the pop-up, make sure you set it to “Media Sync (MTP)”.

Now your phone will show up on an option when you want to run your app in Eclipse.

(Look for dialog box on phone and agree to allow debugging connection with your computer.)

(Also, go to Control Panel | Device Manager and make sure there are TWO entries for your phone, similar to those expanded below.)

Answer 5

After countless attempts, I found the following quote:

If you are using My KNOX, you cannot enable USB debugging mode while the container is installed. Unfortunately, you have to root your device ... - continue reading

Furthermore make sure:

• your USB-cable works
• your connection type is MTP (or PTP in some cases)
• to enable USB debugging before pluging your device via USB-cable

I switched to another device without KNOX (not rooted as well) to save time. Maybe this quote will save someone some time. It was the only explanation to me in this case.

Cheers!

FYI My Motorola Xyboard had an "Off" icon at the top of developer options. Once I tapped that it worked.
