OK to start I rooted using LGUP with a rooted stock 20j ROM.
I eventually flashed the 20L update but went back to my 20j backup because I found it runs smoother.
My issue is that my laptop will not recognize my device via ADB/Fastboot. I've tried re-installing the LG drivers with no luck. I have several LG devices that are recognized this is the only one that will not be recognized.
Any help would be much appreciated.
hm, can you provide some extra info on what you have done? In general what you have to do in order to make it accessible is the following:
Enable Developer Mode
Enable OEM Unlock
Try "revoke USB debugging authorization"
And then reenable USB debugging and try again
Also try with another cable and try some other USB port in your laptop or PC.
Sometimes some USB ports wont recognise the device unless you do some procedure to uninstall the driver for the specific USB port. For now just try to change the port and the cable.

It happend after I flashed JK5 (I lost track with so many updates)
The phone is not recognized by windows anymore, cannot access odin or anything.
I have another vibrant and is still working so drivers are installed and everything.
The phone does recognize the connection, lets you choose, can get into download mode, but is just not being seen by the PC,
Since the other vibrant connects fine cable is also right, it is a problem strictly with this phone.
I tried flashing other roms, modems, and so on via CWM but problem is not solved.
Any help or ideas will be appreciated
I had the same problem. Someone said try usb debugging, & it worked like a charm.
Applications/development/usb debugging. I hope this helps.
Thanks, I tried that, and all the options for pairing without success

If USB debugging is enabled, it shouldn't give you a choice of usb connection mode. Make sure your USB cable is unplugged when you enable debugging, or else it will just tell you to unplug and try again.

I meant to say, first i tried with debugging enabled, did not work, after that i disable debugging and tried Kies, Emdia Player and Mass Storage, still not recognized, also is not recognized when in Download mode.......
Any Ideas?
Prior to the latest OTA I was able to get USB Debugging working by changing the phone to a Connection Sharing mode and then to Ethernet specifically. Since taking the new update I have not been able to get adb to recognize the device. They removed the previous USB mode used and we only have Media and Camera modes now (both of which I tried). The phone itself is indicating that USB debugging is enabled and actively working, but I can't get it to show in adb itself. Any pointers or suggestions would be greatly appreciated.
Steps tried:
Toggling developer mode off and on
Updating USB driver to the latest from the SDK manager
Media Sync Mode
Camera Mode
Restarting ADB multiple times
I had to install the latest drivers from the LG site itself, and change the usb port on my PC....then toggling Media Sync (MTP) and Camera (PTP), it finally gained adb access. Although, even with adb I still cannot root via ioroot.

Thanks, that did the trick!
The part about changing the USB port on your PC, is unclear to me. Did you have to change from a USB3 port to a USB2 port ? Or did you mean that the USB2 port you had previously been using successfully would no longer work ?
I am worried about USB2 ports being required, since many new laptops now only include USB3 ports.

Went from a previously working usb3 to a previously working usb2 and neither worked.....plugged it into another usb2 on the back of my case and surprisingly it worked. Perhaps remove the device/drivers from the old usb ports you had been using then re-install the new drivers again.....maybe that will work.

Do you have a link for the driver? Tried so many and no love.
Is this it? http://tool.xcdn.gdms.lge.com/dn/downloader.dev?fileKey=UW00520120427
EDIT: Above link worked, thanks!
When I tried to connect my rezound to my desktop PC the PC tells me the usb device is not recognized. It used to work where I can connect to my PC and look through files on my rezound, but it hasn't been working for a while. Does anyone know what the issue is? I tried enabling usb debugging and tried installing HTC sync and used some of the settings in "connect to my PC" section of the settings, but it still doesn't work. What I want to do is backup some files and eventually root and flash for the first time. I currently have an S5, but I want to root and flash on my Rezound. Thanks for any help.
Update: I got it work. I think it may have been a cable or port that wasn't working right as I used a different cable and usb port on my PC
Like the title says, all I can get pc to see it as is modem, composite usb device and com port. Can't for the life of me get it to see it as a mass storage drive. The reason I care is twofold, but mainly so I can detect in odin and flash a custom rom. I've searched google and here. Please point me in the right direction. Oh, I'm on FF29.
Also, i've tried on two different pc's, and with two different good cables. First cable is stock samsung.
Tried different drivers, w/ and w/out usb debugging enabled, tried rebooting phone w/usb debugging enabled while plugged into pc, tried booting to download mode. NO LUCK. Any help is much appreciated.

Have you tried these drivers
USB_Drivers_1.5.27.0.rar
https://www.androidfilehost.com/?fid=23134718111255952
Updated 09_26_2013 same as from XDA ---- http://forum.xda-developers.com/showthread.php?t=2038555 ,,,,,, installable via "setup.exe" OR via "have disk" method SAMSUNG_USB_Driver_for_Mobile_Phone s.exe ,,,,,
Hello all,
I purchased this phone a month back and would like to install custom roms/root it etc.
I am unable to get my phone to enable USB debugging and allow access for my PC. (I have a unlocked bootloader). The notification (prompt) for USB Debugging which shows up the phone (asking if one wants to grant access or not) doesn't show up. Hence I am unable to use adb or fastboot to install TWRP.
I have tried using the cable provided by the company on both USB 3.0 & 2.0 ports to no avail.
I am aware that there is a "How to Guide" under the News/Discussions section. However, it hasn't helped me much.
Any possible solutions?
Thank you
PS- When I connect to pc using USB cable I get the prompt asking me if I want to use it for file transfer,PTP or no data transfer.
Are the drivers properly installed?
What does the device manager show, when your phone is connected via USB and USB debugging is switched on?
What happen if you type "adb shell" when your phone is connected?
Enable it in developer option
Allow USB debugging and USB debugging Security Settings) in Developer Options
