[Q] USB Connection Problem Galaxy W

I am having a problem when I connect my phone to PC. I get the attached screen after connecting the cable, and the phone memory drives never show up.
(dark blue screen that shows date and time "Alarm", "Music", "Gallery", and "Voice Search at the bottom)
It happens both in debugging and non-debugging modes. Also, the GPS icon on top of the taskbar starts blinking shortly after connecting. MTB connecting does not start.
I have no idea where this page comes from!!
Thanks

You got USB drivers installed on PC.....is it Windows....or Mac?
What do you see if you pull down Notification Blind?
What is the symbol on the top left Notification ?
Does PC give any message regarding drivers when phone connected, with USB debugging selected on phone?
Are you using supplied micro USB cord?

The USB drivers are fine, It was working before on this PC.
I can not pull down the Notification bar like I do on normal screen.
The symbol on left was for SetCPU notification. I have flashed the stock ROM again and everything is clean, problem still exists.
PC gives no message, even the phone does not charge!
I am using the original USB cable.
Thanks

OK.....I no like this:

Sounds HW related problem!!!
You try different USB ports, different cords, different PC or Laptop....just to eliminate everything but the phone!!!
Can ODIN see phone, in Download Mode?? Here also you need USB Debugging selected.
Something like this, left box should be Yellow:

The only thing that I need to try is a different cable.
It also looks HW issue to me.
I could connect it in Download mode to flash the stock ROM after several connecting and disconnecting the usb cable.
I may take it for warranty tomorrow. Is flashing the stock ROM is enough to have the phone looks like factory defaults. It looks unrooted and no recovery mode now.

it may just be the cable/usb cord!!!
I'd say if you are now on Stock FW, and have restored Stock Recovery, and un-rooted, you are OK for Warranty.......
Let us know how you get on,

Yes It was cable. it works fine with another cable.
Thanks

Try this:
I was having a similar issue and uninstalling and then reinstalling all the drivers, software, etc. didn't work for me. But this did;
http://blog.vacs.fr/index.php?post/2...Samsung-phones
Resolution
1. Unplug the USB cable
2. On the cell phone, dial the following number: *#7284#
Once the last # is hit, the PhoneUtil application is launched. Choose USB -> Modem and then USB -> PDA mode.
The good mode should be PDA. Even if the mode is PDA, switch to Modem and then back to PDA.
3. Plug the USB cable.

[Q] USB stopped working 4.3

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.

Lost USB connection mode...

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.

Lost USB connection mode Fix
Go to Settings and click on storage and then click on the 3 dots at the top right of your screen then click on USB PC connection click on Media device (MTP) or Send Images (PTP) and that's it you will be fixed

Except I don't have any dots in that menu I upgraded to lollipop so I don't know if that could be the reason why. Any other suggestions? I'm desperate here

Quick google search: http://support.bell.ca/Mobility/Sma...ow_to_change_the_usb_connection_options_on_my
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?

Thanks for the reply man. Didn't work though. I cleared every single default setting and app preferences. The problem remains. Funny enough it still persists even after factory resetting.

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'm having this problem also.. Been a month I tried all above suggestions but still no fix

Me Too
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.

Broked
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.....

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.

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.

Help me recover OP3 data

Hi all!
I recently dropped my OP3 and now i have a black screen and touch screen doesn't work. The phone is still on and operating (i tried calling it from another phone and it works). I want to recover data but apparently i have usb debug off and i tried connecting a keyboard with an OTG but apparently i had to activate OTG from phone, otherwise it doesn't recognizes it.
Do you know any method to recover data?
My last chances are repairing the screen myself to avoid the assistence erase all the data, or transfer my motherboard to another OP3, but do you know any other method before these two above?
Thank you

Most likely the connector has become loose (since you have not said anything about the screen being broken) and you can try to reconnect it by yourself.
Another alternative is to see if adb is working and your PC is authorised. If so, you can use the 'adb pull /sdcard' command to copy your data to the PC.
Alternately, search with Google since I remember reading about a method to mirror your screen and then using the mouse to enable whatever you want.

I'll check the connector but the screen has some cracks (tho i've seen screens in worse condition then mine work).
And i can't use the mouse because OTG is not on, on other phones you don't need to give permission to use OTG but on mine you have to,

What about adb? That is the easiest.
I am not talking about connecting the mouse to the phone through OTG. I am talking about using the PC's mouse to manipulate the cursor to the point where you want it on your PC's screen where your mobile screen is mirrored.

I think you are referring to Vysor, but i can't use it with debugg off again. Edit: I see that there are other apps like that but for most of them you have to install them on the phone, i'll search a bit more tho.
As for ADB i tried before with another phone with debug off and adb doesn't see the phone, i'll try with my broken phone but i don't think it will be different.

Just now, I switched off USB debugging in my OP3 and connected it to the Laptop. While the command 'adb devices' does not find the phone, as soon as it is connected, it shows up as a storage device and I can open it and copy data. I think that for this to work, you should have enabled MTP option for file transfer.
Check this on your phone.
EDIT: Check THIS as there seems to be a way though I am not sure that it works on current Android versions since the file locations may be different. Read till the end.

My phone goes in charging mode when connected to pc, and pc doesn't see it.
Did you do that through recovery mode?

No. Tried it while booted.
Now I tried on recovery mode. Still I get it as a storage device and I can copy data.
So most probably your phone is stuck on charging and not on MTP.

I believe so, every time I connected it to pc i had to switch manually from charging to recovery.
I guess my best solution is to buy a screen replacement and repair it myself

Have you tried fastboot flash twrp recovery and then fastboot reboot to recovery

You can try usb c to hdmi adapter , connect to a monitor or tv.
I am not sure but worth trying!!!

From what i can remember, the recovery mode, accessible from the fastboot menu, has a usb access mode.
If worst comes to worst though, i personally have replaced the screen on my OP3, and its not as difficult as it seems or is made out to be. Took me max 4 hrs.
