This issue has been bothering me for such a long time. It started since I updated my G2 to android 5.0.1 lollipop, and I couldn't connect my phone to PC for a long time. File transfer has been so difficult as I have to upload pics and files to Google Drive then DL from computer. What's more, I don't even want to swipe my phone or reset to factory because the backup process would be so difficult without a computer! Spent lots of time searching for fix online but never found one, and I kind of gave up long ago.
Yesterday this issue popped backed into my head and I tried to look for answers online again. After hours of searching still can't find useful tips. Trust me, I've tried all the tips I found online, including change USB ports, change USB cable, use different computer, uninstall/reinstall USB drivers on computer, enable developer option's on phone, enable USB debugging, etc. Non has worked, just as before. I know this issue should be the problem of the phone instead of the computer, and luckily I crossed over a thread of a people with MIUI having somewhat similar problem, and he solved it by installing a MIUI USB app. So I searched for similar apps, and BINGO! my problem solved! So here's my solution:
I went to Google Play and search for "LG USB", and installed the first app says "USB Driver for Android":

I guess the key word is "USB driver", and other similar apps should work too.
The App is very simple. Just tap on the MTP button:

And the long lost USB connection options reappears!!!

My phone is in Chinese but I think it's simple to find the corresponding app and options in English system. I think what the APP does is simply take you to the USB connection options page, which is hidden somewhere in your phone but can't be found.
I guess the problem is that when updated to Lollipop, some phones got this bug that the USB connection type selection menu somehow doesn't show up when connected to PC. While I was looking for solution online, I found that not only G2 users, but people with G3 and even non-LG phones got the same problem. For LG, I don't know what they're thinking as they even took away the "USB PC connection" option menu (as the last picture) in "Settings", making it impossible for users to manually choose connection type when this bug occurs. (I found that other brands' phones kept this option in settings->storage)
Any way, just happy to solve a problem bothered me for over a year and want to share my solution. Wish this post will help people who got the same problem as I did.
PS. It says I can't post links, so I can't post the screen shots' full links. But I guess this solution is not hard to understand even without pics.
Thanks for the solution but in my case - after installation - menu USB PC connection appears but unfortunately disappears in a sec.
Is like someone push the back button .
Probably there is a software who creates the problem but i do not know how to find it in order to close it or uninstall it.
Any idea?
Thanks in advance.
This is my problem:
I am an android developer, i own a nexus 6p, i was using it well, but after i got nougat, i was not able to connect it to my mac. I have a brand new cable from google (A data cable). I have tried every thing i have read on the internet and nothing. Android File transfer does not work, i have tried already. My phone never shown the notification in order to be pulled up and select the type of usb connection. Then i activated developer mode and activated usb debugging and MTP connection, and nothing.
"I will be ultra very thankful if somebody helps me"
Hello, I've had the V20 for a number of months now and love the phone, but I never tested out a data connection before, only to find out that when I use both the LG cable and a Anker USB3.0 cable, my phone is not able to connect to any computer. The system prompt to select the MTP or PTP connection appears, but after making a selection and the computer seeing the phone for a split second, the connection is lost and the USB prompt appears rapidly over and over again. I even went into developer options and set MTP connection always.
I tried a reboot, battery pull and capacitor discharge, and a full system restore. No fix. The only work around I have now is a samba server or moving files with the SD card manually.
Please, if you have any ideas? Does not work in Windows and Linux.
Thank you.
Have you installed LG bridge?

Did you enable USB debugging in Developer options? If no, enable it.
Change the power settings in windows for the USB.
Power options
Advanced settings
Disable "USB selective suspend setting"
Tried all the above

Yes, USB debugging works and I'm able to use ADB with my phone and both the Windows laptop and Linux Desktop. However, neither is able to reliably connect through the typical MTP and PTP methods. I finally got MTP to limitedly work with MTP when I use the LG supplied cable and ignore the USB connection prompt in Windows and Linux. I go straight to File Explorer and access the file directory of the phone. Every time I open a folder or access a file though, the phone rapidly pops up the USB connection message over and over while the file moves.
All third party cables and USB devices are not working other than just charging. In Linux, the error message in my logs is:
usbfs: process 20678 (mtp.so) did not claim interface 0 before use
reset high-speed USB device number 101 using xhci_hcd

Is this behaviour on accessing and copying? You can not copy a file from your Windows laptop to the phone?
Yes, I cannot open folder directories, nor move files from phone to computer or visa versa.
Also. Try to not let the phone screen turn off. Change display time to 15 minutes or something.. Change back when finished. GL

No change.
dbo989, did you resolve this issue? By any chance are you running avast mobile security? I was able to transfer files both ways via USB and had the pull down USB options without ever having to add USB debugging. Then I installed AVAST and USB has become charge only... none of the widely recommended solutions above will unlock USB. I see no apparent settings in AVAST so I will call them. If no resolution then I will trash Avast

No, I never could resolve it. I ended up using Samba to fileshare with home computer, but lost any OTG cable ability. Never used antivirus or security software with my phone.

Just fixed it... turned out to be the port on my PC, I switched ports and its back as it was, no need to enable dev mode or USB debug... its still slow connection... I have to look up Samba solution, never used it.
Thanks for sharing
I just experienced the same problem with the USB connection constantly cycling between being plugged in and not. Windows kept alternating between the device connected and disconnected system sounds. I unplugged the USB 3.0 to USB-C cable on both ends, unkinked and straightened it, and plugged the cable back into the PC and the phone. Hasn't made another peep for the last half hour and the phone is staying in USB file transfer mode. I wiggled the cable at the phone end and still no further disconnections. Maybe I didn't connect the cable securely at the PC end the first time.
This is the first time this has happened since I started setting up the phone this week, so I don't know what to make of it. Regardless, I need to order some more USB-A to USB-C cables since this is my only one.
USB File Transfer Issue - Resolved
Hi, I had the exact same issue with the computer not seeing the phone as far as files. I was still able to use ADB, Fastboot, etc, so I figure it was not a hardware problem. Tried two different computers as well. Every time I selected "File Transfer" in the USB settings, the phone would beep, and when connected to the computer, the computer made the usual chime. The phone would not show up in explorer still.
Previously this phone had been rooted, but I wanted to bring it back to stock. I had flashed the latest KDZ file. Then using ADB and Fastboot locked the bootloader. It seems that the USB issue happened after that. Here is what finally fixed it:
Turned on developer options the usual way (tapping build number in software info) and then turned off "Allow OEM Unlock." Then I turned off developer options. Still, no luck, so I then re-flashed the latest KDZ (H91820h) again, but this time with the bootloader locked.
After everything was done, I set the phone up again, and now file transfer works perfectly.
I did not want to chance locking the bootloader while the phone was still rooted. I learned the hard way about that, and nearly bricked the phone once before. Luckily I still had factory upload saved in the LAF partition.
Hope this helps someone out there.
Turns out it was not fixed permanently

After thinking it was in fact fixed, I rebooted the phone several times, turned off, then on, and all seemed well. Until the next morning. I turned it on, and the same issue happened again. No File Transfer mode to computer. ADB still worked. After being on for a while and getting warm, all of a sudden file transfer started working again. Rebooted, and turned on and off, and it continued to work. I figure its a bad part with a thermal issue somewhere so I put it in the freezer for 5 minutes. When booted up again, the same problem occurred until the phone warmed up. Weird? So I tried something completely different. I downgraded the phone to H91810p and tested again. It seemed to work fine. I put it in the freezer again, and the problem will not show itself. For whatever strange reason the problem appears to be heat related, and ONLY happens with the latest KDZ, Oreo 8.0 The only thing that I can theorize is that the SOC is bad, or there is a bad area of flash memory that is intermittent.
Does anyone have any clues? I am going to put it back in the freezer, go to work, and test again when I get home to confirm.

So i have the LG v20 H-990 (elsa) non rooted phone with Android 7.... Im trying to get it to connect to my pc but it wont work..i have usb drivers and lg drivers 4.2 plus i have lg bridge installed but as soon as i plug phone in...it just starts charging...
So in developer options i saw its set to mtp (media transfer protocol) and i cant cgange it even if i select sometging else it just goes back to mtp... So i tried turning usb debugging on...yet no joy....its not that the PC is not picking up the phone but more like tye phone is not letting connection ....well connect...please help?? I want to try and get some backups going and updates and also play with photos and vids ....please please please help
You have an H990 or an LS997? Also, the phone will charge, even on MTP(which is what it uses to communicate with PC), so you don't have to try to force stop it. Have you gone into device manager or ADB to verify your PC isn't reading the phone?

I have the h-990 and yes i have gone to device manager and there is nothing...
I've been having the same problem I couldn't change USB connection type from mtp to charging or ptp etc...what I found is if I try to change it from the developer menu it doesn't want to work, but if I bring down the notifications shade and expand the notification for it and change it with the popup it tends to work most times...I did have one time I couldn't get it to work at all until I factory reset my phone (wiped and reflashed ROM but I'm rooted and rom'd)... Sometimes restarting both phone and PC works...I'm not sure what it is it seems to be different on every PC I hookup to ...oh and sometimes I've toggled USB debugging off then on and that helped....so without several people having the problem and all trying to collect information about types of PC and cables and other individual variables I figured its some kind of glitch or some code error somewhere that under certain circumstances makes the v20 stupid, that likely won't be fixed or solved...this is just my experience , i thought maybe one of the things that seemed to help me might help you....good luck
V35 "Select USB Configuration" Glitches out, USB Tethering option Greyed out.
Okay, First Post here: (long time lurker)
So I know that this was not an issue before pushed update to oreo, because i have previously been able to adb remove bloatware from the phone. I have factory reset the phone after the pushed update to no avail. (Verizon, Amazon/Unlocked V35).
I am finding that I can not get the phone nor computer to recognize a data connection, and I have tried 4 different usb cables. When I go to Developer options and tap on "USB Configuration" it flashes and...nothing. If I tap it repeatedly, the "USB Configuration" popup shows (extremely briefly) and disappears promptly. Furthermore, the "USB Tethering" switch is greyed out.
So...
1. No Data
2. No Tethering
3. USB options in Developer Options glitches out
Is this perhaps some sort of Verizon Provisioning, or a corrupted firmware perhaps? I would like to unlock bootloader and root etc...
Thanks in advance guys!
Update: lg promise warranty exchanged
So I did an lg promise warranty exchange, and first thing I checked was usb mode in dev options. Worked! Updated phone all the way over wifi. Put verizon card in phone, and lo and behold usb options glitch out again. Okaay. Tried usb...WORKED!
So, unsure what happened with last phone.
Actually, last phone was totally Amazon branded out. This replacement (same model) has Zero Amazon branding. :silly:
