First of all I am a big-Noob.
My LG optimus one P-500 is in stock ROM.
My Problem :-
Earlier USB was working fine but now
when I plug it in to the AC Adapter it charges OK but when I plug it in to the USB after that it only charges and neither the Phone nor the PC recognizes the USB data connection.
I have tried
1) Power off the phone and remove the battery for a couple of seconds and power it back up, after doing this the USB does not connects. Not even recognised by PC or Phone
2) Device manager also does not detect anything.
3) Uninstalled modem driver and reinstalled USB driver but no result.
Please help
Thanks in advance
Cheers
Request again
Dear mates
I have really very high respect for the forum so please help me out.
ThanQ
Cheers
This happened to me twice before. I had to send it to LG's Service Center because I saw no way of fixing it since the computer wouldnt know what to do with it...
If you have custom recovery installed, you might be able to flash an original ROM over it. This wasn't an option for me before and it seemed like the only way to fix my phone. Don't take my word for it though. Try for the service center first if possible...
Did you try going to settings and choosing Mass Storage only?
Also, change the USB port of the cable with which you connect your phone (plug the cable in another one - try this with all ports if it doesn't work the first time)...
Before going to any service, do a backup and Factory Reset your device, then try again...
Oh, and disable LG modem from Device Manager after installing the USB drivers.
USB not getting detected
I am trying in choosing Mass Storage only.
"Also, change the USB port of the cable with which you connect your phone (plug the cable in another one - try this with all ports if it doesn't work the first time)..."
Not helping either
Disabled LG modem from Device Manager after installing the USB drivers.
No use
Before going to any service, do a backup and Factory Reset your device, then try again...
I will try this definitely but going to service means 3-4 days without phone . really very scary .
thanks mate
anymore help
Okay , I did face this problem before and I did about hundreds of advice from my friends but this is the step that works.
I discovered that this happens when you do crazy **** on your sd card with applications such as titanium backup or root explorer. Curiousity kills the cat.
Firstly you need:
1) Usb Card Reader [Of course which suits with your sdcard]
2) Computer
Firstly, you want to dismount the sdcard from your phone and mount it to the USB Card Reader.
Connect the Usb Card Reader to your Computer.
You should be able to gain entry to the sdcard
Next,clear everything on your sd card then place your sd card on your phone back and do a factory reset. If you don't do a factory reset then you must do it all over again if you decided to connect the usb to the phone. After reset-ing the phone , try to connect your phone to the computer. Congratulations.
Note: This works for me but it doesn't meant that it will work for you , but I think that this is worth the try.

Ur phone charges through usb that means your phone usb port/usb cable is ok. Do this :
Uninstall the drivers, restart the pc and try connecting the phone again. Remember not to install the drivers again. Win7 save a dump of old drivers and i think it will auto detect it. Post results here.

Got exactly the same situation with USB(on different PCs) and also Emergency mode on every reboot(taking battery out for about an hour helps).
Did SD wipe though not sure about factory reset afterwards, gotta try it one more time...

I have tried uninstalling driver and just plugging in with USB but still neither PC nor phone detects USB connection.
I have tried it on Win7, Win Vista and WinXP.
respected mates please help me.
I am on transfer in June so don't want to take chance with Service centre as of Now.

Are you sure you are having the latest driver?
try this:
Code:
csmg.lgmobile.com:9002/client/app/B2CAppSetup.exe
install it,
(you may have to choose language from the last tab, 1st or 2nd option)
and choose P500 from "driver installation"
I didnt experience this issue but if i cant help im sorry.

Try another cable.

None of the above methods worked on mine as well - same results on different cable(pc/os).
Will try to flash rooted original firmware via custom recovery, del custome recovery and root and send it to service.
Hi guys,
I have a problem that's fairly common but I can't get it right
I can't install new drivers for my SGS2, my pc/laptop don't recognize it anymore.
I have flashed an ICS rom before so I also tried the Nexus S drivers, no success.
I have tried to work with Android SDK manager but since my laptop can't find my phone, it won't find it as an adb device.
I managed to get back on 2.3.3 via CWM manager but my USB jig also doesn't work anymore.
I have tried everything regarding Kies and new drivers so I'm pretty much out of hope... Anyone with suggestions?
You could use mobile odin, also if you flash back to ics you can reset counter with triangleaway and then flash back to gb

Problem is that I can't flash back the old bootloader..
I think the logical step would be to try another PC, given you've tried everything else & nothing has worked.
You could also maybe try Heimdall (search for it on here).
Also, if you haven't tried different USB cables (in particular the one that came with the phone), give that a shot. Also make sure you're connecting the phone to a powered/mainboard USB port & not a hub port. Also, try toggling USB debugging in your phone settings.
That's about all I got. Try these things if you haven't already, but definitely try another PC.

I have tried different ports with different cables, different pc also won't install the drivers.
Usb debugging on/off doesn't work either.
Going to try heimdall today but it has something to do with my phone since I flashed so many files before with my pc and with my laptop.
Will post after I tried.
Yeah it sounds like a phone issue given you have been able to flash firmware with that PC previously. Good luck with Heimdall, fingers crossed for you.

Nope, heimdall can't recognize my phone either.
Running out of ideas here.
I guess there isn't an option to flash the old bootloader other than Odin huh?
Unfortunately Mobile Odin can't flash bootloaders yet, so Odin (and probably Heimdall) are your only options. Either way you're going to need USB.

My PC recently stopped working properly it connects but always fails flashing via Odin, I managed to set up Odin etc on GF laptop so at least I can use Odin if needed. Could you not try restoring your PC to earlier date and see if that works or uninstall everything to do with phone, kies, Odin adb etc and do a fresh install of everything

My phone doesn't connect at all.
I have tried uninstalling everything including drivers and such via USBDeview.
The problem lies with the phone itself I think, not my pc.
I think I have found the problem.
I think my USB port from my phone is broken.
I will try to reset my binary counter with Triangleaway, then flash back original firmware without root and then send it for repair to the Vodafone shop!
Hope this works

I have the same problem. I came from CM9 and now I cannot connect my phone to the PC. I am using CheckRom V6.
Do you think it has to do with the bootloader? Or might the usb port be broken as well?

Yeah I think that it has to do with the bootloader, but a broken usb port is also a common problem.
I still have warranty so I will just let Vodafone repair it.
If my pc still doesn't recognize it after that, then I'm screwed.

Ok but if it is a bootloader problem, we should not be the only ones having that problem.

Correct, I have searched the whole internet and there are some others with the same problem with the bootloader, but they can connect their phone and install the drivers I guess. I have tried everything regarding new drivers and such so I reckon that my usb port is broken.

I'm on Cyanogen Mod 9.1.0 with stock kernel!
Sorry for the bad english friends!
Does the phone charge when connected via USB?
If not: your USB connector might be broken.
If yes: did you change anything on the phone since it last worked?
The phone charge with USB cable and even with the original charger.
The connector is working with other phones. I thing something is broken...not software issue i think.

The only way is to send it to Samsung, but i'm on CM 9 and since the phone is not recognized in download mode, i should flash the original firmware with mobile odin, am i right? It will be all right for the warranty?

Try any of these combinations:
1. Ensure you have kies is up to date.
2. In Device Manager - uninstall driver (!) & then reinstall.
3. In Control Panel - click on troubleshoot, hardware and sound, configure a device.
Option 2 worked for me.

its either bad cable, bad usb port on your computer, or your computer thinks it has the right driver and no further action is required.

Well, I have this experience while flashing my friend's phone and here what I've done:
-reboot my computer
-connect the phone, kill all kies related process (I'm using Windows) and start odin. If odin recognise your phone at this point, you are good to go else you might want to reinstall usb drivers.
-use full wipe odin files I found from internet (I got from the pirate bay with search key ics full wipe)
-got few files in that folder. Hope you know their function. Or you can ask here.
Hope this helps.
edit: you also can try to plug into different usb port that have different usb controller

If Odin adds and removes quickly, this looks like your USB cable is dead, try flashing with another - Genuine- one
I had a similar issue while flashing my former SGS1: flashing process interrupted suddenly at 50%
A similar kind of thing happened to my phone as well when I was upgrading to 4.0.4 from gingerbread via Kies. The installation got stuck when the phone was in the download mode and I had no other option than to disconnect. But yours got stuck while using Odin. I would suggest you to flash the firmware again. I hope your phone goes into download mode now. As for the drivers, uninstall everything related to samsung from your PC and then reinstall it. DO NOT UPGRADE SAMSUNG KIES IF IT ASKS YOU TO DO SO! AS I TOLD YOU A SIMILAR THING HAPPENED TO MY PHONE. MY PC COULD'NT RECOGNIZE IT AND I REINSTALLED EVEYTHING AND IT FINALLY SHOWED SOME SIGN. MAKE SURE YOUR ANTIVIRUS IS FULLY DEACTIVATED WHILE YOU EXECUTE THE FLASHING OPERATION!

first of all, while your phone is disconnected from USB cable, can you enter download mode?if no, then try to find someone that have JIG. else, as leech4 said, this might caused by your USB cable. OR might caused by your USB port of your PC. as i said earlier, try to repair your USB driver (not sammy USB driver, but your PC's usb driver). flash using ODIN, and kill kies services from task manager as kies will conflict with ODIN later. here i give you LSJ link(thanks to ApriliaM3) in case you don't have. extract the zip and use all the PDA, PHONE and CSC file. you can even use PIT to re-partition your system. (tested and proven to be working). good luck mate.:good:

Wow, I suspect this kind of brick or what so ever others called it. I've read some where, and they talking about JIG. If what they mean is the same like what I understood from my electronic knowledge, then you have to find someone that have JIG to do further troubleshooting directly from your board, not via usb. Well, I'm just saying. You might want to seek for other solution first since it's your device.
