Ok guys so here´s the problem. I ususally leave my USB setup as "ask on connection", so whenever I connect USB the phone will ask me in wich USB mode I want it to be.
I have always used my phone like this and it has always worked. Up untill today.
I have just flashed my phone do JPC (Froyo) Firmware, I was just about to reload my agenda back to my phone through kies and that´s when I noticed that my phone will NOT connect to my PC in Kies mode, no matter what I do, it simply won´t work. I do want to make it clear that my PC DOES NOT have any driver issues, I´ve always used it like that and it has always worked, the simple fact is that when I connect the USB cable, the phone asks for the connection mode and I select "Kies", and absoluteley nothing hapens, that "MTP screen" does NOT show up, the phone does not show up "USB connected" or anything like it, and my PC obviously doens´t recognize any sort of connection. In fact, if it wasan´t for the fact that the baterry is still recharging, it would be just as if the phone simply didn´t have the USB cable attached to it.
Now to the funny part: both "mass storage" and "media storage" modes work perfectly. I have tested my phone in both my desktop PC and my notebook, it happens in both cases so it´s defineteley a phone problem.
Well, I went all the way back to flashing with the older JP6 firmware and there it was, USB Kies mode was working again. Reflashed to JPC and the Kies and I happily saw Kies mode working again... that is untill I reselected "ask on connection" mode in the USB settings. Apparenteley there´s some bug in the JPC firmware, USB Kies mode will NOT work when you have the "ask on connection" mode on, you have to leave USB Kies automatic if you want to connect it that way.
Could anyone please confirm this problem? And does anyone have a hint in how to solve it?
Thanks

Kies works under Launcher Pro now as well... shock horror !
I´m using the stock launcher in the 19000XXJPC firmware, not sure wich launcher it is...
I've got the same problem - not sure what's causing it.
Did you restore settings / system data from Titanium Backup by any chance?
what I did to get it working was.
format the Internal SD, wipe cache, factory reset everything.
After that I just copy stuff back into the internal SD.
Kies works now but I still don't like kies, it's a piece of crap.
Whenever Keis is being annoying to me, I just unmount the internal SD card, works a treat after that.

Nope... I think it´s a bug in the JPC Release, didn´t happen in JP6...

I'm currently on DK28 and anytime I plug my phone into my computer via USB cord it just shows that it's charging. This is an issue since I would like to switch to EB13 and I need to be able to use Odin for the EB13 modem. I've tried uninstalling and reinstalling the Samsung drivers several times and not just on this computer, on two others that I have. I've also tried multiple usb cords and it's all the same thing. I've Googled the problem and everything I've tried has been useless to me, including the PDANet thing. So my question is is there any other way for me to be able to update to an EB13 rom without having to connect via USB? Or does anyone have any other ideas as to how I can fix this? I've been just using a microSD card adapter to put things on my SD for awhile now so that's never been a problem but I can't use Odin unless my computer recognizes my phone I guess.
HELP!!

Have you gone into settings, applications, development and unchecked USB Debugging?
I also have read numerous times where people have found the USB connector on the phone had something bent and was preventing a full good connection.
Good luck
You have got to be missing something drivers can be 32 or 64 bit make sure you have the right one for your computer. Is usb debugging checked in settings/app/development. Randy Shear has alot of step by step stuff for on youtube that might help
Yeah I have USB debugging checked and my computer is 64 bit which is also what my drivers are.
Turn off anti virus and dl driver again thats what I had to do. Reboot both devices also

Tried that too and apparently that wasn't the problem. :\
I read where one person who was having something like this was told to turn their computer off; plug in the phone to the usb and turn the computer on and it worked.
Maybe try that?
I've had this problem, got real annoying after a while. I ended up reinstalling the drivers and turning off usb debugging and it would go into mass storage. Re enabled and tried again, and it continues to work.
Thanks for trying to help guys but unfortunately neither of those things worked either.
I had this problem. I flashed a different ROM (try downloading a new ROM from the phone) then flash it after following the appropriate instructions.
The ROM I had that problem with was Nebula ROM, I fixed it by flashing Bonsai v2.0.
Well I have now tried that as well and even that didn't work. This is so ****ing annoying.

Try flashing another ROM instead of Bonsai. I hate that you're stuck, but I'd try a few more ROMs before giving it to a Sprint Store.
I had this problem as well and did everthing mentioned here as well to no avail.
Now here's what worked for me.
First, install drivers on another pc (ensure that you connect, wait for drivers to load, disconnect and reconnect your phone at least twice..sometimes a takes a couple of connects to install the drivers fully).
Next use odin to flash DK18 stock firmware. When you connect your phone..suddenly mass storage will be back again. You can then load whatever firmware you wish.
This has worked on my phone and a friend's with the same issue.
I had this happen to me on 2 different machines:
- First time: A restart fixed it
- Second time: My phone didn't like the usb ports on my work laptop's docking station. The cable would only work with the actual laptop's usb port.
I have not had this problem until recently and not sure what has caused it. My phone is not showing up when I mount my SD card. Also undetected by ADB. I have tried multiple cables, different computers, and also reformatted my computer and installed fresh drivers just in case. My phone does however show up in Odin and I can flash a modem no problem. I was thinking about wiping my phone back to stock and going from there, but I am afraid that will not fix it and I will be stuck at stock. =(
Thanks,

Had the same problem. Had to reload the drivers even though my other Epic was recognized just fine.

Same here, its' like it woked one day and didn't the next. I had 2 problems, one was the fact that only half of the usb jacks on the front of my desktop work (dumbass), and I had to re-install the drivers found on Samsung.com. My computer also will not recognize the sd card until you turn on mass storage from the drop down menu on the phone after the usb is connected.
What I did was turn on USB debugging, connected the phone in the drop down menu, then went int control panel>device manager> and looked for either "Other" or something in the USB connections. I found Samsung Android. I clicked that and hit update drivers from Windows Update. It took like 30 minutes to load all the necessary drivers then connected fine after that.
I have tried uninstalling/reinstalling drivers. I am pretty sure I have tried the update driver thing through device manager, with it saying I already had an update to do driver. I have also tried with/without debugging and also manually selecting use as a mass storage device. Just kinda weird it shows up in device manager, just ADB doesn't recognize it or as a mass storage device. I am starting to think it is something more with my phone as it doesn't show up on other computer and tried other cables. May just say screw it and try Odin.

You can uninstall the drivers, then let Windows Update find the drivers again. It needs 5 drivers altogether. My problem was similiar. It wouldn't recognize my phone with USB debugging on, yet had no problem recognizing my other Epic so was sure my phone was screwed up. After Odin it did recognize it but wouldn't after rooting and putting on a GB leak ROM but again the other phone was fine. Forced driver update and has worked fine ever since. Although one phone shows up as F and the other as E. Not worried as long as it works...lol.
I uninstalled the Galaxy S 64bit drivers but the uninstall option that came with the package. I plugged in my phone, it attempted to find drivers and said unsuccessful. I click, search automatically and it comes back with nothing.
Also it says it is Samsung CDMA Technologies.
Edit: I just tried manually updating the drivers by pointing to the driver location instead of using the provided installation. I see only 4 drivers installed. Samsung USB Composite Device, Samsung Mobile Modem Diagnostics, and one other I am unable to find the name of.
There is also a CDC driver.

I fixed the problem. In case anyone else runs into it, it's simple to fix. I was afraid to ODIN back to stock in case something was wrong and unable to root/cwm again, but I grew some balls did it and it's now working flawlessly. Must have been something messed up with the system files on my epic, that even a wipe and reflash from CWM would not fix.

Did you root and reflash your ROM and try it?
Yea, I rerooted and flashed my rom. Everything is working fine so far, along with my SD card and phone showing up on my computer. Before it was just showing up as Samsung CDMA Tech. now it is showing actually showing the samsung model number. So something happened with the phone before. Not exactly sure.

Glad you got it working. You were lucky Odin still recognized it.
I'm running 4.1.1 and every time I plug my device in (With stock USB) I get "USB device not recognized"
I've tried another USB. I've downloaded Kies (Will only connect wifi), I've tried reinstalling drivers, I've tried using another computer as well. I've also enabled/disabled USB debugging,
The USB connection notification only appears sometimes, and even when it does my computer still won't recognize my S3. After I reinstall the drivers my phone does say "Connected as a Media device", but then the notification goes away..
FYI, I'm trying to root, that's why I need a direct connection with my computer so badly.
Does your computer has samsung kies?
You say drivers. Idk what u mean but all we need is samsung kies.

I tried your method a few days ago, and it didn't work. I tried your method again.. it doesn't work.
I had this issue. All I did was get some good ol canned air and blew the dust out of my micro usb port. After that it connects just fine. Was about to do a warranty exchange before I did this.

Its your rom on the phone that's causing this. If you want to rule it out, why don't you just do a nandroid backup and install stock rom or perhaps the same rom clean from start. I had this issue before and it was fixed with reflashing clean rom.

I should probably mention the phone charges will of the USB cables but none of them work with the PC. I can't tell if it's a software issue or internal..
I think it's a computer issue, what was the other computer software you tried on?

Tried it with W7 & Mac, neither recognize the device. Android file transfer just tells me "no device found", and the Kies on mac doesn't work either.
I still won't update my computer from XP cause all I read are device errors with upgraded versions of windows... see if you can get your hands on XP and try. Just as insurance, you have gone through device manager and removed all drivers for the phone and then pushed the proper ones from Samsung, correct?

watch the screen closely when you connect the phone to the pc. does it even recognize thst some usb device was plugged in?
After a few moments, (with the phone still connected) click start,right click on my computer, select manage and select device manager.
are there any yellow question marks on the right side under the computer?
Open the modems (click the + sign) is there any SAMSUNG USB Modem? (should have no yellow question mark)
Open Universal Serial Bus controllers, do you see the samsung Mobile USB Composite Device?
There should be NO yellow question marks or exclamation marks anywhere on the right panel.
If there are, there is a problem with your computer settings/drivers or services.
If you followed my "cannot fail" steps EXACTLY in the order I had it, and did not skip anything, you should be without any problems with the modem connectivity. That includes the uninstallation of any samsung drivers previously installed.
If you do not even see the samsung modem, the cables or the phone may be your problem.
Post your results and I'll help you to get it working. Also mention what your compurter's OS is.

My bad, speed reading is not always good... thanks for pointing that out.
Anyway, did the OP ever get this resolved? Bobolinko's steps are thorough and if that didn't fix it, why don't you just try to go into download mode and ODIN a stock ROM with root injected into it already? It's another option...
Did you try buying a fresh new cable to connect the phone to the computer? I only have those issues with corrupted USB cable and a messy laptop...
Also when that notification appears for me I go to my phone USB section and tells it to mount as storage...and if its on storage I switch media than back to storage...always work for me.

As soon as I plug my S3 in, my computer recognizes a USB is active. In Device Manager, I do not have Samsung USB, all I have is "Unknown Device". I'm not sure what you mean by yellow exclamation point in the bottom right, but there's nothing in my notifications. However, I do get 2 yellow exclamations in device manager. One in Universal Series Bus, and one in other devices
Hi there.
Check this
On calls hit *#7284#
Check if pda is enabled then click on qualcomm settings and see if mtb+adb are enabled.
If not then just enable those.
Hope this is your problem.

I've tried this as well. I get this error:
"Connection problem or invalid MMI code"
The problem is with your computer, and not the phone. You CANNOT get it connected with a problem in the USB settings.
click on the yellow exclamation items and DELETE or UNINSTALL them. then reboot the machine and it should reinstall automatically. If your DRIVERS that are already in the machine are bad, you have to get them updated or replaced. uninstall KIES from the computer, reboot, and reinstall it. go to samsung's site and download and install the driver for your comuter.
The one for the xp is: SAMSUNG_USB_Driver_for_Mobile_Phones_1.4.8.0.exe
install it to your computer and be SURE there is no error while it installs.
then check again your device manager list for any yellow problem areas
connect the phone and wait a while, then, disconnect and wait about a minute
then again, connect the phone, and wait at least one minute. open the device manager page and see if there are any yellow area problems again.
are you positive you have the latest window updates?
you can sometimes right click on an item and do the driver update and fix a problem.
You clear all the COMPUTER END PROBLEMS you have and the phone will connect. That, my friend, you can take to the bank.
Good Luck!

Hi all, how are you?
I have a Galaxy Nexus unrooted stock with Android 4.3 (JWR66V).
After the update to 4.3, my device has stopped working in MTP/PTP mode.
I mean, When I connect my phone to my Notebook USB port, thus nothing happens on my notebook or my phone.
When my phone is connected to my notebook the notification dialog to select between MTP/PTP modes doesn`t show up anymore in the phone (it only says that is charging).
I have tried to re-install the drivers on my notebook, and It didn't fix this issue.
I have also tried to the a factory reset on my phone, and It did't fix the issue either.
Besides, I tried also to connect the phone with a different USB cable and it didn't fix the issue either.
Please, May someone help me?
Thanks in advance
Please, May someone help me?
I have no idea of what is going on and why USB stopped working after 4.3 update?
How do I troubleshoot this issue?any clues?
I figure out that on Android 4.3 I have ti go to Settings->Storage->Usb Computer Connection and manually select the connection mode...
(I am not sure Why the notification pop up doesn't show anymore on the phone when I connect it to the PC using the USB cable)

You are totally right... dont know the stu... option doesnt appears clear. On my S3 I did the same, but the option wasnt visible... you must click over USB (even it appearing as dimmed) then a USB CONNECTION (or something like) appears you must click over and then a screen with MPT option will be available... For godsake WHY such thing isnt available on settings or on shortcut menu by default is beyond my understanding.
Hi!
I have LG G3 D855 Vodafone ESP with free ROM v10i
Have one problem:
When connect USB LG to PC, dissable (I don´t know like) USBs Mode, only charge,
How fix this optiom to change an other one, options to MTP?
Thanks
Giving this a bump, as I now have this problem as well. Just today is when this occurred. I've had the LG G3 for about two weeks now and always had the option of switching between full charge mode or MTP, but now I suddenly lost the feature all together. I rooted my phone about a week ago, and made all the changes then. Had the feature all the way up to yesterday and now today I am noticing it is no longer there.
Rebooting the phone doesn't bring it back either. Any ideas?

Nevermind! Embarrassing but fixed it. Issue was the USB cable not being plugged all the way in the slot.

The guy above gave you the solution, whether you are on kk or lollipop, it's still in your settings. Just gotta find it.
That would be an easy fix right? It's why I'm asking here. Once I made the mistake and press the charge only option and now it will not allow me to go back and choose any other option such as MTP or PTP. Know any workaround for this?

Sorry no I haven't. It's really perplexing because I wiped the phone clean (which should have set all settings to default) and yet the problem remains.

I've been having this issue for around a week now after switching to USB Tethering. Now whenever I connect my phone via USB to a computer (any computer) it defaults to the USB Tethering mode.
On Android Lollipop there are no options to change in the storage menu.
I have noted that "plug and pop" fails when the usb cable is connected "unfortunately plug & pop has stopped" I suspect this maybe the root cause of the issue. I have run a task to correct permissions but this hasn't resolved this force close.
Any help suggestions apart from those already provided (that I have tried) would be appreciated.
I'm also having this issue for about two months. I've since given up. Also tried factory reset, multiple times. Would love to get this resolved. I have the D851 for T-Mo.
I should also add that I've tried multiple custom ROMs (Bliss, SkyDragon, CM, and one or two more) as well as the stock. Nothing works.

I've uninstalled "plug and pop" which has stopped the force closes but not this issue. I've also booted into recovery and cleared cache. No joy after that either.

Also on lollipop, had MTP/PTP etc option until this week, no suggested fix in this thread works
In addition my PC is routinely telling me the SIM or SIM2 unlock is "required" to use the phone. It's, like, wigging out. It's vibrating when there are no messages as well, probably repeatedly telling me that it's charged and I should unplug it. Kinda stupid, like a lot of programming in this stock ROM (popups, volume messages, other s/w irritations that are just amateurish). The device is good but it seems to be time to replace the OS.
PC is an Ubuntu 17 rig with KDE; phone is rooted; logcat & shell still work. Odd.

Having the same issue.. I've been using cm12 /12.1 for months and all of a sudden my PC won't recognize my G3 . it charges when connected to the PC but that is it. Just found and watched a video on YouTube with another person Having this exactbproblem and it was due to oxidation on the "gold teeth" within the phones charging port . He fixed the issue by lightly scraping/cleaning the gold teeth with a screwdriver. He was brave . im going to try the storage/3 dots/ USB connection suggestion tmw when I can access the computer and will share an update.
Heres The video mentioned above.....
https://youtu.be/pmpmH4NyG
I am also having this problem on my D852 running 4.4.2.. last time I used MTP was at least a couple months ago, and now there's no USB options at all. I have checked Storage settings, there is no More Options anymore. I have also tried Application defaults reset, still no change. On mine the USB tethering option connectivity is completely gone- the option is greyed out as though the phone no longer recognizes it has a USB connection at all.
It seems pretty obvious to me that this is a hardware failure somehow - everyone seems to be having this problem after several months of use, and across multiple G3 models and multiple version of Android. In mine the USB functionality is *gone* entirely yet the phone still charges. Does anyone have a *code to perform USB diagnostics?? *NOT* USB debugging- actual onboard hardware self-tests like the radio, touchscreen, etc. *#*#4636#*#* does nothing for USB.
Solved missing usb connection options missing
I got bored at work one night and reread these forum entries and noted the possibility of there being a hardware issue with the USB port. Rather than wait until I got home I decided to see if there was a diagnostic mode hidden somewhere that would check out the hardware... and there was. So I plugged in the codes appropriate for the international g3 and the diagnostics screen popped up. Woohoo. I thought I'd just run the full suite of tests and that was the last thing that worked after the phone rebooted. It then started coming up with a message "security error" and went into a boot loop. Wait it gets better. I booted into TWM recovery and did a restore to my previous backup. This resulted in the phone becoming soft bricked....arrrrghhhh.
My next step was to download the D85520H_0 kdz file and apply that to the phone with the kdz tool after putting the phone into download mode. When the phone rebooted it went into the diagnostics mode which I then exited and my phone rebooted into stock lollipop and was working fine. All USB connection modes were once again available. There still aren't three dots on the storage screen though. There was a firmware update to 20I available so I decided to let my phone upgrade before rerooting. However it seems that 20I has some "fix" in it to prevent both the LG 1 click root and purple drake from working on it. In the case of one click root it seems to root the phone but it actually doesn't. In the case of purple drake it just sits on the screen waiting for device even though my phone is connected correctly.
So short story is that I suggest you download the the 20H firmware kdz for your country and apply it with the kdz flashing tool after putting your phone into download mode and then rerooting but NOT upgrading to the 20I firmware unless there is an update to either of the rooting tools. If you're lucky you might get your usb connection options back.

Friend and me both bought 2 G3s from the same shop. My friend doesnt have this problem while I do. I do not want to reset my device. Is there no solution yet?

Click to expand...
Click to collapse
Step1: Connect your G3 to the computer
Step2: Go to device manager in your computer
Step3: Search for LGE composite device and uninstall the driver
Step4: Install LG PC suite
Step5: Press on the 'Connect with USB' button
Step6: Search for the device. The software will say device not found and it will provide an option to reinstall the driver.
Step7: Keep your G3 connected to the computer and reinstall the driver and you are done. G3 will show options to connect via MTP.
