This may seem simple but are you sure the phone has USB debugging enabled? It's only turned on when the Nitro is in "PC Mode" in the USB mode settings.
ADB *should* detect the phone regardless of firmware.

Try using a different USB port. If you are using a USB 3.0 port on your computer, try a USB 2.0 port or vice versa.

USB debugging is definately enabled. I think driver install is bad. Where in device manager is phone I only see under drive? Ill reinstall driver with path to LG drivers again

I'm not sure what you're saying here - are you saying that you can see the removable storage for your phone's memory card?

Figured It Out
I finally figured it out. It was a driver issue. I used USBdeView to uninstall the USB drivers. Then installed LGUnitedMobileDriver_S4981MAN36AP22_ML_WHQL_Ver_3.6. Then I installed the LGMobile Support Tool and ADB finally recognized the device. SuperOneClick worked fine and rooted quickly after that. Now running CM9 nightly. Thanks for support and assistance. The "how to root" instructions should be updated to include the versions of files that work best and include LGMobile Support Tool as well.

Unable to connect phone to pc via usb

Hi,
I have rooted my phone with rootbox rom and i cannot seem to connect to pc using usb cable,I have tried everything (replacing cable,installed another rom liquidsmooth,updating drivers,troubleshooting with kies) nothing seems to work no matter what i do the windows still shows mtp driver installation failed.I would be very thankful if someone could help me out here,..Oh yeah and i am able to connect it to pc from recovery by mounting usb storage but not in normal mode

I had this issue with 3 different phones of my own. I ultimately had to remove the Samsung drivers and reinstall them. Do a google search for captivate drivers, you should find an xda post on this somewhere.

[Q] Rooted Nexus 7 Unique MTP Issues

Ok so I have a rooted nexus 7 that won't show up as an mtp device ever since I rooted another nexus 7 on the same computer. I have uninstalled all the drivers and re installed them a million times with device manager and USBDview nothing works. It connects to other computers as an mtp device, however ever since I rooted the other nexus 7 on the same computer it won't work. Also I don't have access to the other nexus because it was my friends. Obviously it's a computer issue because it connects to other computers as an mtp. I'm really out of things to try as I have searched for this problem, but only found people saying to re install the drivers. I would really appreciate some help because I don't know what to do. Thanks.

I also have weird issues. What I usually do is make sure the Nexus is configured for only one connection. So for MTP mounting I have PTP unchecked and USB debugging unchecked. Then I plug into the computer.
If it doesn't mount as MTP, I find it's usually because Windows has attempted to connect via ADB drivers. So I go into Device Manager and uninstall the device under "Android" while checking the box to remove drivers for the device. Then I unplug the Nexus and plug it back in, and it uses MTP drivers. I've always struggle with these driver issues for the Nexus, i don't know why it's so difficult. Good luck!

When I had issues with my mtp I had to uninstall adb drivers then plug my device back in so it would use mass storage and install the drivers. Somehow I have adb and mass storage working now with USB debugging on.
Check in device manager when you have adb uninstalled and see what your device comes up as.

I uninstall the adb drivers but for some reason windows automatically installs them right back instead of mtp drivers and then if I go to update drivers and select mtp as an option it says it won't work

When I try to install the mtp drivers it says "Windows found driver software for your device but encountered an error while trying to install it...your device can't start" Then it automatically installs the adb drivers. What would be the reason it won't let me install the mtp usb drivers? Has anyone else encountered this?

Turn off device. Stay it in download mode. Connect it with PC and start internet via other device or wifi. Now in control panel go in device manager. Here you will find your device (without driver installed). Click on it and update drivers for your Samsung device.

No USB detection in Windows

I was having an issue with my i9250, my phone would not be recognised in windows when switched on normally, so I replaced the USB flex inside,and I'm still having the same problem.
My computer will detect my phone in fastboot mode, or in odin mode, but I will not be detected normally, nothing appears, not even unknown device, and I have enabled usb debugging, flashed mutiple stock images but I still have the same problem, have you got any more ideas for me?
Thanks.

what windows you using? did you enable usb conection on phone? if you are on windwos 8 look at softwere update to install new usb driver for our phone

Make sure you have the right drivers installed. There is a stickied thread that contains all the steps of returning to stock 4.3. I believe the first step deals with getting the right drivers and installing them correctly. I would suggest following those steps.

Connect phone in usb debugging mode and then Try to manually install the drivers from device manager.

Switching between MTP/PTP have fixed some issues for me.
