I have problems connecting my OB via USB. First , i've tried 2 no-named micro usb cables but they would only charge my phone . The PC doesn't respond ( no sounds , no connections). I installed and reinstalled LG OB drivers from the official website on 3 different laptops. Now , a friend of mine gave me his Optimus p500 original Usb cable. Same result , the phone is only charging. I really dont know what to do. My phone wont recognize the USB connection and neither the PC won't recognize it.
Suggestions ?
PS : stock rom 2.3.4 v20q and i tried factory reset too.
For my OB i use the cable from my SEVivaz and its work fine, and I use another cable from an Samsung perfectly work too. What rom u use stock or cwf, coz u can make hard reset if cannot use your cable then try again to go in recovery mode

i have the stock GB 2.3.4 v20q . I tried 3 different cables and 3 different laptops but neither the phone or the laptops recognize it. The phone is only charging...... I cannot do any data transfer between the phone and the PC.
I saw the same with my OB. I tried different cables and different PCs. My phone even did not charge properly, most often it only charged when I turned it off completely (sometimes even this did not help, removing / inserting battery helped in this case). Sometimes it charged very slowly but it did show it is charging - just like it did not recognize it has been plugged in. In this situations the whole phone became very hot.
I send the OB to the warranty, they replaced the usb port. This did not help, then I send it to warranty again, they replaced the board, since then everything is fine.

USB cable or usb drivers on PC .
Two weeks old i would have gone back to the seller .
jje
It might be a driver problem. I had the very same issue when I have bought my Galaxy S, and there was a funny trick to resolve the problem: pull your USB cable into another hole. It helped me when I have had my connecting problem.
I hope I could help you!

its NOT a DRIVER PROBLEM, becouse when it works, it work on all PC's, when it doesnt WORK, it doesnt TO ALL PC's.
There are 2 answeres, THE PHONE, or USB CABLE. I DONT THINK ABOUT USB, but CAN BE....
Did you install Kies? If not you may be missing some drivers, although your PC should recognise your phone as an external drive even without drivers.
I would take it back under warranty.

It's possibly due to condensation on micro USB port of your mobile. Try cleaning it with rubbing alcohol and keeping your phone under the sun or in dehumidifier.

abhjit could be right but if you check on all custom rom threads people are having problems with usb connection
the latest ics releases of samsung ( even JB i believe, not sure tho ) have this problem plus full root problem,
Remove driver in windows then use usb it should auto load correct driver

Just clean it as is. You might be able to see the problem, but you will need a good magnifying glass or loop to see it.
I took some photos I found on the web of a dirty port and colored in the contamination I found on mine.

I have the exact same problem. My device doesn't get recognised by windows 7. It doesn't ask me if I want to use the phone as a pendrive. When plugged in, it only charges the phone. Sometimes the phone does not even realise that it has been plugged in at all. I dont think that its a problem with the pins because I have tried using an OTG and been able to connect to an external hard drive and copy files. Also I have been able to use PC Odin and flash a stock rom using a usb cable. This makes me think that all the pins are fine, and that its a software problem. Something has got glitched and not getting un-glitched lol!
Current Rom is the here

one thing you can try.. is to completely uninstall KIES off and remove all samsung usb drivers off your computer. When I say completely uninstall Kies, I mean totally removing it, from your system registry files and including Samsung folders that you can find in Program files or in program files x86..
After that, restart your computer and reinstall Kies and/or all samsung adb /usb drivers again.
Don't forget as well to plug your usb cable at the back of your PC since mostly USB ports coming from the back of it has strong usb signals than the ones at the front.
Hope this helps.
Don't forget to hit me up a 'Thank' if I've helped you some way or the other.
Cheers!

isolate the issue first...get another usb cable, and if you have another computer (aside from the one your normally using at), try to plug your phone on that computer and see if that pc will detect your phone.
If not still, then that's the time you can already consider that your phone might be the one having the issue.

Well I guess, that would prove the point that it could be your phone that might be having the issue bud. After all, you tried different options already but still came up with the same issue.
I'd suggest you may need to take your phone to SSC and have them check it.
thank you all for your support friends ...i have been able to repair it...i opened the cell phone thoroughly cleaned the usb module and reattached the connection cables after detaching and voila...thank God... :laugh:

Hi, I am using LG P970 and am on stock V20g firmware.
I do not have root access.
The problem is the micro usb port is facing issues and i can use it only for charging and absolutely nothing else.
I some how wanna root my phone.
The warranty period is complete so i cannot go to the srevice centre for a free replacement.
Is there any way.
There was a way initially with Gingerbreak but that used to work only with Froyo.
Please help me root my phone.
I cannot connect my phone to PC via Data cable

I just wanted to send my phone to support with same problem - only loading battery, no usb debugging or mass storage connection.
But i found out, that my connector at phone was just dirty (much dust) so i cleaned it with some piece of plastic (carefully).
The dust was at the bottom, not at the pins itself, it prevented the cable from slipping in enough to connect to the shorter data pins. (check with a flashlight).
Maybe thats also your problem...
Had the same problem in mine. Used those air sprays that clean keyboards AND!!! a tooth stick After that - everything was working again.
And from now on, I ALWAYS close the cap of the micro USB port
There is also could be a problem with USB controller. Make sure you connect device to USB2, not to USB3.
So this seems to be the same problem lot of people are facing and solving it by various means... Here is a list of things I have tried, but still not working -
1. connect to PC after selecting "connect to pc" in settings > more > usb connection
2. revert to stock rom and stock kernel using mobile odin and try to do (1)
3. restore nandroid from 2 months ago when it was working
4. cleaning with qtip (dry)
5. tried usb switcher app
6. tried newest jb 4.1.2 from eyebee's thread.
Any thing that I left out other than service center?
Usb Fix
I fixed two other Notes and a SII by this simple method:
Look into the microusb connector on your phone, and see if the pin in the middle is centered. If not, bend it straight (Carefully!).
Yes, I know it sounds stupid, but it seems people just slam the usb connector into the slot, bending it down... This causes the phone to charge but not to see the usb connection.
Hope this helps.

Tried to bend it towards top, didn't workout...

By default its placed a bit down and forcefully bending it may damage the usb port and then you cant even charge it
Thankfully its still charging...

Hmm.. Something new you taught me, but didn't work.. Am I supposed to go "into" that mount usb storage screen and connect after I am in that "if you leave this page, we'll unmount" screen or before entering that screen?
Edit -
Never mind, tried both, both failed to work. I assume if it was working, I would have heard a beep from my laptop at least.. It didn't find any new device in both cases.
try using new cable. or borrow your friend's cable see if its working. its the basic to check thing but many forgotten.

Tried in office today.. No cable works... Tried 3 cables, one aftermarket one, one is of note's, one from nokia 5800 xpress music...
Didn't workout. All charges. No storage
you installed stock rom.. but didnt work..... so then it is not the firmware
you tried diff cable....but didnt work.. so then it is not the cable.
so then it must be your phone..
can it connect to mtp?
this may sound funny but it worked for me. take out the battery and the sd card. leave it out for a couple minutes. then reboot

You might be on to something here - It says Charging (USB) even if connected to wall socket! Should it say (AC)?

yes I am. even though the phone when normally booted won't be recognized by pc, but when in download mode, it usually does as I have had the same problem but that happens to me since I enabled the mass storage mode and then neither worked. mtp or mass storage.
when connected to charger, it shows ac and when connected to pc it shows usb

I have the same problem here with my n7000.
Its happened after flashing ics roms. N7000's have some kind of faulty chips which causes emmc brick bug. But the issue we're having is a USB Brick.
Flashed many kernels & roms etc. but still no signs of life :crying:
Different cables & pcs, no luck..
As we are able to use mobile odin only, i flashed stock GB and sent for warranty. I always avoided to trigger binary counter so it was easy for me.
However, results were disappointing. Technician guy said that usb port is working and there is connection between both devices but something blocks usb connection. There were some unremovable files which shouldnt be there and they couldnt delete it as the section was read only accessible.
ADB isnt functioning too..
I guess the only possible way is to find a tech guy capable of replacing emmc to solve the issue from source..
Please let me know if there are any updates from your side.

hey try software called StickMount Pro... worked for me
Hello. I have been using S4 for few months now and had it rooted. It is an amazing phone and work perfectly well
Recently all of sudden, when I put my cable in for charging, my phone wont detect it. Nothing happened on the screen (no "charging sign written", no lightning sign at the top right corner). But if you just leave it as it is, the phone will be charge to full.
Same with the USB as well. I had no problem of connecting my phone to my PC via USB before. But now my PC cant detect my phone anymore even with KIES.
Both of these problems turn out at the same time. Initially I assume something might be wrong with the usb port of my phone or something hardware related.
Weird enough, when I try connecting the phone to my PC in Odin Mode, the PC can detect my phone.
I had tried unroot my phone with a stock firmware and the problem is still persist. Had google around and find no solutions.
Anyone had any idea to work around this problem? It is really troublesome to not be able to connect my phone to my PC
Do you have the latest drivers installed? Have you tried a different cable? A different USB port?

try un-installing the device drivers from pc. then reinstall again.
did that too. not working.
I dont think the problem is the pc driver. As I mentioned before. when I go into odin mode. it can detect my phone.
And its not only usb that cannot be detected.
Had problem with the charging too as what I mentioned above even when I charge using a power source directly
