I have searched this forum, found some Sync issues but nothing that relates directly to my issue. If I just didn't see it, point me in the right direction please!
I have a TILT2, stock ROM, I have made some reg mods for text msg notification, Data speeds & auto rotate via G-Sensor. My phone was syncing perfectly fine for a few weeks and I have the USB to PC "Enable Faster data sync" unchecked.
I lost sync a few days ago, I rebooted phone & computer figuring that would fix it as it has in the past only to find I only get charge light, no data connection. I don't hear the bum-bum audio indication that it is connected, and the device does not show under Device Manager nor mobile device manager and my connection methods include USB & Bluetooth.
Here is the caveat, I can sync to the computer through my bluetooth on my PC and I do hear the audio tone connection. I figure a reg change affected this, but I reviewed my changes, nothing dealing with USB, and I even reverted back to a Reg backup from prior to the problem occuring - no luck. I have swapped USB cords, nothing has helped.
Does anyone know of registry setting that would disable my USB sync? Do I have a defunct device?
Assistance appreciated - Dan

Is this of any help to you?

Thanks for the link - I had found this before, and it really deals with no connection at all. I ran through most of the post, nothing helped. Considering I have sync via Bluetooth, it is not firewall.
Looking at restoring my computer to sometime last week, see if an update that came through caused this.
I'll post more when I done the restore.
OK - Update. I restored my PC to prior to issue, no luck. I disabled my security suite, no luck. I have tested the phone on another PC, it acts the same. communicates via bluetooth, but only charges via USB.
I am starting to work my way through the phone registry, is there any specific setting I should be looking for?
I'm just going to throw in a suggestion here: have you tried using a different cable? Often times the cable is the bad piece of the connection, but people don't even think to switch it out with another one.
And as well as the cable, have you tried a hard reset on your phone?
same problem!
i have the same problem. went to htc and they told me sorry you have a 3rd party rom so we are not going to help you.
yes i have treid 4 other pc's and 3 difrent cables and no luck.
please help!!!!!

I had the USB port go out on my TP2. I used the SD card to flash the sock hard SPL and then used the SD card to flash the stock T-Mobile ROM. Then I sent it in for warranty exchange. I suggest that you do this and then seek help from HTC.
cool can you perhaps help wit how to do it? please?

same problem here and the problem that the battery was draining even when the phone was off. call htc and the next morning the ups was at mine house to get the phone. 7 days later the phone was back with new motherboard. a had started a tread in general of this problem
Yep, mine too. I had to send it back to HTC UK for repair after the USB socket stopped working - came back with a new mainboard.
It looks as if it's prone to failure as I'm careful with connecting and disconnecting cables and it looks as if this one is already starting to go again!
Can't fail HTC UK Repair for it's great service though...
Looks like a bug to me, Suddenly I do not see the "USB connected" message on the notification bar! I have to disconnect USB and change mode from mass storage to something else and then change it back then connect USB and it shows the USB connected message with mount option.
Never had this problem with any previous builds. Also, I see the accurate battery mod shows "plug" sign while USB is connected but no "USB connected" message or mount option!
Any comments people...anyone with this problem on JI5 leak?
Simple question first. Did you leave de-bugging enabled? I updated my device thru Kies (one of the lucky ones it seems) instead of flashing Eugene's or the Odin mount and I haven't had that problem. I think I saw someone in the orginal JI5 on Kies thead mentioned this too. I tried to replicate their bug but my seems to 100% good. What's your OS?
its a bug, with mine is seems to come and go

Thanks for the reply. I flashed it through ODIN on Windows 7. Also, USB debugging was never enabled in the process. It seems like a bug because it comes and goes, randomly. Maybe this was one reason Tmobile told us not to upgrade...

Good to hear I am not alone with this problem...thanks for the reply...
hopefully we'll find a workaround...
Just wanted to note here, flashed to stock, formatted internal sd card, upgraded to leaked JI6 and the bug still exists, hopefully OTA JI6 fixes this
Tried OTA, erased everything, flashed from scratch still the same issue...hopefully someone has a solution, if not then this adds another reason for Froyo update
That's wierd. I upgraded to OTA and problem went away for me.
Sent from my SGH-T959 using XDA App
It's not really a bug. There is an option under Settings > Applications > USB Settings. Mine wasn't showing up either so I swithed it to "Ask on connection" then plugged the USB back in and that worked. Then I switched it back to "Mass storage" and now it immediately gets ready to mount. I guess you just have to set it that first time.
Its a bug with leaked JI6. This thread started with leaked JI6... Think he recently changed headline. And you solution was temporary fix with leaked version problem would come back. Can't comment about OTA since the problem went away with mine
Sent from my SGH-T959 using XDA App
Ok, Well I can let you know that it doesn't come back with OTA. You should flash JI6 The other builds are buggy.
wow, for those who went all the way to reformatting internal sd because of this im sorry.
all you have to do is go to settings> app settings> usb settings> and change to ask on connection
thats it, i would not really call it a bug
oh yea, and thats with JI6

THIS solves it. Just did that and everything is back to normal. With that out of the way, this JI6 software is close to perfect (the RFS file system thing is the imperfect part). This is the software this phone should've launched with. Now if they can just go to a proper file system in their 2.2 update, Sammy will have a beast of a phone.
Thanks for the replies guys. I have set the default USB to "mass storage" instead of "ask on connection" as I don't want to make a selection each time.
Now, when I connect the phone I see USB connected and sometimes there is a USB connected message in status bar with no mount option and sometimes there is no USB connected message at all... now sure what's going on. I've been seeing this problem since JI5.
I've also read some threads about this in QnA forum..thanks...

Just for the heck of it, if you haven't tried already. Check off debug mode. Because when you plug in usb debug mode pops up and maybe usb will also every time
Thanks for the reply... Yes I now I leave the USB debugging to always enabled. This is the only way the USB mass storage option is always presented on USB connect.
Hopefully Froyo fixes this as I've seen some other people having the issue as well...
I have never seen this issue on JI6. It always pops up "USB Connected: Select to copy files to/fom your computer" in the status when I plug in the USB cable. It's never failed, even when I had USB Debugging off.

Just FYI, I was having this problem when I flashed the JI6 update via ODIN. Mounting would only work when I had usb debug mode on. However, I disabled USB debug mode and then went to
Settings -> Application Settings -> USB Settings
I then changed it from mass storage to ask on connection and then back to mass storage and it gives me the option to mount in status bar just fine when I connect it to the computer via usb.
HTH.
I noticed that after the update i don't get updates ffrom the market place anymore?
Anyone experience the same thing?
Are you using the auto update? I'm not sure it tells you if this is on.
When I connected to my mac (debbuging has to be left on) I get a menu to either connect to kies,mass storage and one other.
So basically. before I would plug my phone into usb and it would give me a couple of options. But now it plugs in, computer says "di dong" and the phone shows as charging.
But the phone doesn't ask for option, nor can I find a way to manually prompt it to.
help! (needed desperately for internet tethering)
had the same issue a couple of times
what i did was just unplug it again, wait a minute and plug it back in. The second time i would get the notification.
Maybe you havt to try another USB port on your PC.
Had the same problem.
Switched it off and on again. -> problem fixed
When plugging in your phone into usb, just go to settings-->Applications-->Development and check the USB debugging(uncheck and check it back it is already markeck).

If you can't mount SD Card and your pc doesn't recognise it then Your USB is bricked. There is a tutorial on the forums that will help you with that
Counterintuitively, the setting you're looking for is under Wireless and Network. Go to USB Connection and set it back to "Ask on connection."
this may be the cable error .change other one try again.

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":
imgur.com/x81eztb
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:
imgur.com/j7enxFn
And the long lost USB connection options reappears!!!
imgur.com/cZjO8xl
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.
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

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.
