Got a replacement phone yesterday and recovered from backup. After the backup was complete I was not able to run activateSync. The device connected fine and I could explore it via the PC just could not sync with Outlook.
I think the problem is the device thinks it is a new network device and adds a LAN connection. Being at work the firewall blocks it. I seem to recall a menu when I first set this up allowing you to set what happens when ActivatSync starts and how the phone should react. I did not get that this time due to the recovery from backup I suppose.
Does anyone know how I can stop this device from thinking it is a new moden and just sync?
Did you set the USB connection popup to ActiveSync? You've got the modem, Sync and mass storage choice, if modem is chosen it will obviously appear as a modem.

The options that you mention are in settings (or all settings, from the settings tab and then menu), connections, USB to PC. You can tell it there what to do when your device is connected to a PC via USB.
Hope this helps
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.

Hello guys,
I bought a ZTE AXON 7 A2017G and wanted to use it as personal hotspot on my PC via USB. The interface MUI of this phone is not so good not intuitive and when I switch the USB Tethering supposed to do just that it's bringing a screen of how I want to connect by USB and not working to share the 4G connection to my PC. I tried all options to ‘only charge’ to ‘MTP’ etc. I use Windows 10 64bits, already installed the driver from the phone and I tried many solutions like changing the network adapter driver from device manager to RDNIS 6 or ZTE RDNIS ect. But it still doesn't work actually it does stuck the UI screens related to network when I connect the phone.
Anyone has a solution to make this work without rooting the phone? I still have a warranty so I don't want to root it while I still have it.
Thanks !

You don't lose the warranty automatically by unlocking. They have no way to know if you relocked it before sending it in (and even if you send it unlocked, there's an EU law that says that they have to prove that the software modification caused the problem). Broken screens aren't caused by LineageOS afaik...
Okay, back to the topic at hand: I have a Win10 x64 PC. I connected the USB cable to the PC, then to the phone, then went to the settings and enabled USB tethering. After a second the PC asked me if I wanted to connect to a new network. So there's definitely something wrong on your side.
After you hit tbe USB tethering option don't touch the connection options that appear (the MTP, PTP, install driver stuff), just leave them as-is
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
