Pc doesnt recognize my device ? - LG Optimus 3D

My laptop doesnt recognize my device. It all happened when i checked an option in development (application option - in settings) with usb connected .... Also tested on another laptop... not working ... is there any solution ??
Charging happens ... but driver installation fails. . .

Dear cldwar,
Same here and i did everything to solve even back to stock but no chance; just charging but usb not recognized... At last i found the below solution by myself... Still i am very confused that what is causing this issue; hardware or software failure?
Solution:
1- Download " Usb Mass Storage Watcher " from market. Install and run then choose " auto mount usb " option and save.
2- In telephone screen, 3845#*920# to enter hidden menu. Go to port setting and set " AP USB " then check retain after reboot and save-reboot
3- After phone reboots, choose mass storage from settings-sd card or applications-development-usb debugging...
4- plugin usbcable and connect phone. Wait a few seconds and then u will see that phone is being recognized by the computer.
5- In phone screen, usb mass storage watcher application may prompt several times so just press save to exit...
6- To disconnect, either disconnect cable directly or deselect mass storage mode or usb debugging... Phone may be unstable temporary while disconnecting usb...
Hope all these helps...
Kind regards,

You have the drivers on the phone itself, on the LGE folder.

PC suite update problem

When ever i connect my phone and try to update phone or pc suite i get this error
"The update check files have not been imported from the update server or the mobile phone is not connected"
How to solve this problem. . ..
Check that in settings menu of the phone, under the applications/development section usb debugging is enabled (this allows phone to communicate with the update software, or at least on my laptop it only works with this option enabled on the phone).
Then if it still does not work you can click the button on the update softwares main screen to install the usb drivers which should solve the problem.

nope it didnt solved the problem. ..

[Q] USB connection related problems

Any1 will any solution plz help coz my phone is at mess atm and cant flash anything.
the source of the usb issue may be your computer.
1) did you always use the same usb port for your phone?
2) how old is your computer?
3) do you live in a humid environment?
I live on guam, and on my older laptop (only two years old!!!), running winxp, 3 of 4 usb ports are no longer usable due to corrosion. they give errors and even when working, sometimes I could lose the connection by moving the cable slightly. also, the last usb port is now getting difficult to use because it's hard to plug in anything
so, if you answered yes to #1, try another port and be prepared to install the drivers again.
if you answered yes to #3, be prepared to replace your usb if they are indeed corroded
well thnx for answer,but my pc is new like 7 months old,usb ports are working just switched mouse and phone mouse working phone not.its driver relater before i had that error and some1 from xda told me to delete everything(kies drivers) related to phone and his drivers and it worked i also see that error(code 43 is common) but fix with uninstalling driver(worked before now doesnt).thing is that something at that moment didnt work well on phone(last time it was my external sd card had to format it)and now pc keeps repeating same error.simply even tho all drivers are installed i get device not recognized,and under device manager it unknown device,also when i tick option to see hidden devices i see omap 3630 but state is unconnected.

When transferring files to and from pc, do you use the original USB cable that came with the phone? Because when i use other cables, i have this issue, when i use the original cable, no probs at all.
if that also doesnt work, try formatting internal and external SD cards

i use original cable and also i did format both external and internal cards several times my first problem is kinda more important atm.
ok i tried connecting my phone to secondary pc running xp gave me same error but simple uninstall of driver and reinstall made it work cant fix it on win 7.
Edit: damn phone wont connect when in download mode cant flash anything -.-.
Connect the phone and go to device manager
If you see the i9003 driver uninstall it then connect the phone to pc again
now windows 7 will download the driver automatically
that's how I fixed my problem

I have just cleaned with some alcohol but it still occurs.
Seems like u have hardware related issue, I would suggest to get it checked by SSC.
But before u give ur phone, make sure u have stock rom with stock unrooted kernel. U dnt have cwm recovery and ur download counter must be 0.

MTP Initialization issue
Hi All,
I'm new to use Galaxy R the same model. I don't know the issue i'm facing is directly related to MTP Initializer or not but the issue i'm facing is I'm not able to access the subdirectory and file system of my phone in PC. At initial When I connect my mobile to PC I was able to access the files and at that time MTP initializer message never appeared as notification but from few days ago whenever i connect my mobile to PC i'm getting notification of MTP initializer to my mobile and I'm not able to access subdirectories and files(music, video, photo) present in mobile although the root folders are appearing.
I thought this might be an MTP issue so posting this in this thread. Please help me how can I access(Copy/past/delete to/from PC) my all files.
firstSmartPhoneUser,
Try to access your files using USB mass storage. Go to Settings-Wireless and network-USB utilities, and click "Connect storage to PC" button. Then connect USB cable and tap "Connect USB storage". If that doesn't help, you can try to connect wirelessly with "Kies air" app, or something else, like MyPhoneExplorer (this app needs to be installed both on the phone and on PC).

I used odin to flash 2.3.6 firmware in download mode and it installed successfully, i wanted my mobile to connect to external storage device(i.e. pen drive) so i made a cable myself and also attache charger power source to that cable(hoping it would work.e. mount & read pendrive) ..After that my mobile wouldn't cnnect to my comp or laptop via usb data cable....it would charge but a usb data connection was not possible .. And finally after trying various methods i think it now is a hardware malfunction(becoz of me) and it should be given to a service center..
Rest all is working fine i can flash diff roms , camera ,wifi all working now using pacman rom so i thought service center would charge me more if i gave my mobile as it is.. they could easily charge more for seeing other rom installed So i wanted stock rom flashable by CWM..
So anyone's help is appreciated.. thanks...

what I understand from your posts is that your phone is perfectly fine but there is a problem with your pc and data cable.
Check with some other data cable,and re-install the samsung drivers for "device not recognized" error.
Use other usb port to check whether its a problem in your pc.

i never saw any such option on any rom yet!
whenever you connect with usb to a PC you get USB connected notification..click on it and enable mass storage.
never saw MTP & PTP in usb connections.
Which rom are you using?
If its 4.+ then try this

In Device Manager in Universal Serial Bus Controllers i uninstalled everything from ASMedia XHCi controllers to USB Root hub... all of them, then clicked scan for hardware changes then i connected my device to computer, then clicked the app USB mass storage for ics and JB ....on computer the elements(USb Root hub, etc.) reinstalled and there it detected my device as unknown device,,,,then for 5-10 sec a message flashed
something like this ,,...". I.I.I.I.I.I.I.I.I Ata mass storage " then it stopped showing not installed...
Using Pacman rom ..does have mtp,ptp,mass storage options..( when i tick any one of the three options it force closes)...
I googled over net on connectivity issue and will need sum time to format c drive and then try again...:fingers-crossed:
I wonder once in odin multi downloader i ticked the debug option only then i clicked delete driver option which may have caused the problem.......
Finally problem solved...replacing charging IC ( as the repairman said) solved comp connection problem then flashed stock rom....

yes to all :/

If ur rooted install multirom and install cm13 as secondary os.. then connect to ur pc while ur in cm13 it will detect the driver after that unstall cm 13 and connect as u do normally
like if worked
hey i found away around it thx though!
How did you fix the problem?
"hey i found away around it thx though!"
But why in the name of all that's holy would you ask the question and then not share the answer for others who regularly have the same problem? Keeping info to yourself is the best way of maintaining your "zero thanks" status...
oh sorry for not sharing what i did to solve the problem! here is what i did!
1. connect phone to pc
2. unlock
3. swipe down and touch the notification that says "usb for charging touch for more options"
4. select the option you want
easy
