Cant connect to computer after flashing CWM (NVflash) - T-Mobile LG G2x

Hey guys, after flashing the new CWM via NVflash, I found my g2x wont connect to my computer. I get the noise on the computer when I plug in my phone and I can see the USB symbol on the phone. Ive tried uninstalling the driver and letting my computer reinstall but it says that it cannot install.
This seems to be directly related to CWM.
Thanks,
Matt

Stuck at downloading

So in attempt to find my way to cyanogenmod 7 today i managed to brick my phone using odin3 one click. i was able to get my phone back into download mode after reading a few tips. so my new problem is my computer saying "usb device not recogniced. one of the usb devices on this computer has malfunctioned'. i've tried reinstalling the samsung drivers for my captivate and that doesnt seem to fix the problem. Any ideas? And if i can get odin to recognize my phone, should i master clear everything before trying to flash it back to stock?
Re-install the drivers and try again. Be sure to have the ODIN 1 Click open before connecting your phone in download mode.
also try different USB ports. wouldn't be the first time a port caused a connection problem.

Flashed KG4 successfuly. Whent to Root it with ODIN, now USB won't recognize.

As it says, I flashed the KG4 ROM perfectly, and went to root it following this guide:
http://forum.xda-developers.com/showpost.php?p=15973153&postcount=211
And the 1st flash went well, saw the red Fugu fish, and boot looped as needed. Rebooted then into Download mode to flash the second file, and windows will not recognize my phone. Just gives me an unrecognized device error. I reinstalled the Samsung USB driver kit, the Ericson kit, and still nothing. (Did restarts between uninstalls/reinstall btw) And I've tried different USB ports on the PC. Still nothing, and obviously ODIN will not see my phone to finish the flash... Did I miss something? Anyone else hit this issue?
unplug. plug into a different usb port after restarting the computer
Still a no go.
Damn, after several Uninstall and re-installs of Samsung's USB Driver pack (Direct from their site), I FINALLY Got it to connect and finished my flash! I Don't know why it was so picky...
thats good to hear

[Q] Boot Loop. USB not recognized. SD Card won't mount

Essentially What's wrong:
My phone is stuck in a boot loop, computers won't recognize the usb connection, and my sd card won't mount. My SD card is, however, recognizable if I plug it directly to my computer using an adapter.
What Happened:
I rooted my phone using CWM and Odin in order to remove bloatware and enable tethering. After enabling tethering, my computer stopped recognizing my phone. I tried everything to fix it including factory resetting my phone, formatting cache, data, system, and sd card all under the CWM boot menu (hold volup+home+power). Soon afterwards, my phone got stuck in a boot loop. On startup, it hangs on the white "Samsung" logo. While trying to fix the issue, I noticed that my sd card won't mount.
What I've tried:
I've tried this method, but it requires that I either have usb access or access to my phone. I've tried reinstalling the Samsung driver fifteen times. I've tried formatting the SD card in my computer. I've tried using different computers. I've tried using different usb cords. I've tried clearing the registry on my computer, I've tried scouring Google and these forums for a solution. Maybe I'm blind and missed something.
What I'm trying to do:
The way I see it, I need to figure out a way to flash the stock rom back to my phone. In order to do this, I need to get my usb to recognize. If I can do this, the rest is easy. Does anyone has any ideas on what can be done?

The phone not connecting: I have had this issue before. If you go into the device manager on the computer and show all devices, you can remove all the samsung usb drivers and the root usb drivers from the computer. Reboot the computer and leave the phone unplugged. it will reinstall the main drivers. reboot the phone and hold the buttons to enter recovery, it should still work even while stuck on samsung logo. connect the phone to pc and it should reinstall the drivers and connect properly.

Do you remember at all the name of the drivers that need to be uninstalled? When I plug in my Droid Charge, the computer attempts to install the drivers but it always fails. Under device manager I will then see "unknown deviced" labeled with a yellow exclamation mark. I uninstall that, then plug the phone back in but the same error occurs.
If there are other drivers that I need to uninstall, then I don't know what they're called. None of the devices in the manager say anything referring to samsung.

go to device manager and choose: view >> show hidden devices
then under the usb drivers look for and uninstall the SAMSUNG if any and uninstall the : Generic USB Hub if any, and uninstall USB Root Hub if any, and reboot computer.
THANK YOU
How don't know how I managed to miss this when trying to fix this over the past week+, but it worked. Getting rid of those root usb devices got my computer to recognize my phone, then I was able to easily use Odin to boot it back to the stock rom. Thank you so much. Crazy how such a simple solution can be the answer.

Hello, have tried uninstalling the USB drivers but Windows 10 re-installs these drivers upon restart. My Samsung SM-N750 is still not detected on via USB, and therefore cannot proceed with Odin firmware flash. Do you have any other suggestions? Many thanks.

[Q] No ROM, can't adb sideload!

So I wiped my phone, went to flash the unofficial kitkat CM rom, and found out I had the wrong recovery version. No biggie, I thought, I'll just reflash my backup ROM. Well, it wasn't where I left it, so now I'm stuck without a ROM to flash. That was okay, though, I could just push one via adb. Then my computer gave me the "USB device not recognized" thing, and so I've tried reinstalling drivers, cleaning the registry, rebooting many times, and all to no avail. I'm lost! Wise ones of XDA, what can I do?
Bump. I really could use some help, I use my phone for work and school and it's a paperweight in it's current state.
I'm guessing you have no access to an sdcard? Looks like you need to use Odin to go back to stock then reroot and unlock. Try uninstalling the drivers then boot your S3 into download mode (hold volume down, home, and power) follow the on-screen prompt, then plug your S3 into the computer to force install new drivers. Now, unplug and pull the battery and try flashing stock, and root/unlock. Try another port, keep the computer plugged into the wall, and also make sure you're using the Samsung USB cable.

No sd card. My computer shows the same "USB device not recognized" message while the phone is in either download mode or recovery, and while using my samsung usb cable and a new one I bought yesterday evening. I've deleted every driver for it, tried every port, and it's the same thing every time. EXCEPT, for some reason, when I plug it into my USB 3.0 ports, it shows up in device manager under "other devices- unknown device", but when it's plugged into my USB 2.0 port, it shows up under "USB controllers- unknown USB device (invalid device descriptor)".

If its not connecting to your main computer, try another computer. Honestly though, I think you need to purchase a cheap sdcard (format it to Fat32) and put a rom on there. Cuz you can still access download mode and also recovery correct? Maybe by then, there will be a few more replies or some idea that will get you in the right direction.

I just have my laptop. I've bought an sd card now, but I don't have a reader. When I fix this I'll put a backup on there I think I'm just going to reinstall windows and get a fresh start. Then maybe I'll be able to ADB sideload a rom.
I had similar problem
After I screwed up my device, this was the way I got the right recovery installed in order to flash 4.4
I cant post links in posts yet, I'll pm you the link.

Is my Device bricked?

All I see is a google logo, not rebooting just staying on the screen. I am pretty sure I deleted the operating system, but I can't seem to get in recovery. What lead up to this was me not being able to connect the device to windows over usb, nothing in device manager, I couldn't even get adb to connect even through twrp sideload. But now I think I caused a whole new issue. I'm just trying to get back to stock rooted lol. Advise?
Edit: unpluged battery and replugged it in, got into recovery now, still having issues connecting so I can flash a rom.
Edit: I have the google usb driver installed from the android sdk. I still can't see my device in windows device manager nor I can't see it through adb. still searching around for a solution.
Edit: I found my old rom still on the device so I was able to install that to actually use the device. I still can't seem to connect to the pc in any way though. I have usb debugging checked drivers installed. Windows just doesn't seem to think a device is there.

Try toggling MTP and/or PHP in USB options.
Your device might show up as an adb device in Device Manager.

Use a different usb port, different cords, or even a different computer, until you get a pc to recognize the phone.
I had this. It was because not all USB leads have data. Even some that do are wired different. Use the original or HTC work fine with N5 as I've both brands
