USB of LG O1 not getting Detected by PC - Optimus One, P500, V General

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...

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.

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.

USB Trouble - Need Serious Help

Please take the time to read this:I flashed and installed SkyRaider a couple days ago and I noticed when I connected to my PC that my PC started recognizing it as HTC Phone (or something of the like). This apparently really screwed up my drivers on my computer because I installed iKReaM and now I can't even get into disk drive mode...it doesn't ask what connection type I want anymore and my computer just says "USB Device Not Recognized". I tried uninstalling the HTC Driver Installer but that didn't do anything either. This is not good as I ran into the same problem when trying to root my friends Samsung Fascinate and never go the problem fixed. Anyways...my phone worked perfect before and SkyRaider evidently messed it up pretty good...to say I am pissed is an understatement. If you need any more info please let me know.
Please link me to the newest HTC Drivers as well, it would be much appreciated.
If no one can help I will have to do a clean install of windows 7, which is not an enjoyable experience

You will have to buy the pro version to push files. That would be your easy solution.
You can always use recovery to get into usb mode as well.

I can't get into recovery anymore using usb mode, computer doesn't recognize the device so no way to use it...and I would use the Wifi app instead of using a usb cable? I see what you mean by easy but I don't wanna avoid the problem...I have a brand new $1600 Alienware so I would like to have it fixed lol...if need be I may just have to do a clean install
I know this isn't your actual problem but just for the record, AirDroid lets you control your phone and push files to it with a web browser and wifi for free.
(I tried linking it but I guess I haven't made enough posts to include links yet, easy to find by searching the Market tho)
You might check under Settings/ Connect to PC to make sure the Ask Me option is turned on.

When you plug your phone into your computer does the phone start to charge?
If so restart the computer and plug the phone into a different usb port. Check device manager and see if you have it listed in your usb devices, or you have an ! over a usb. Most of the time this ends up being an issue with the computer it is being hooked to, not the phone. The computer isn't launching the driver correctly to show the phone that it is connected to a computer, and not just a wall outlet.
Even when I've had this issue, which is random I have still been able to use recovery usb to manage it. Make sure when your in recovery you mount the sdcard before enabling the usb.

1st make sure which one is the problem, is it from the phone or from the pc. have u try to put the cable in other usb port on your pc?
Try to re-flash your rom once again. If that is not working too, reboot your phone in cwm. make sure the cable is connected between your phone and the pc, then select mount and usb in cwm. select mount usb. see if this working for you.
<-----If i helped u
Thanks for your answer but I've already tried all those options... I'm deseperate now. :/

Does it charge when the USB cable is plugged in? E.g. does the phone state that it is recharging?
If in Windows, check if the device manager (Start Button > Right-click on Computer > Properties > Device Manager) still detects 'something' on the USB port, if you see a yellow exclamation mark, perhaps reinstall the drivers for your phone. (Flashtool comes with drivers IIRC). In any case, it might be worth a try to run SEUS with the phone disconnected, then it'll offer a 'repair' option, after which you must select your type of phone and connect it, hopefully the tool does not rely on the same driver. This would flash stock rom and stock kernel to your phone.
Should this fail, if your battery and WiFi still work, perhaps you can engineer a solution that downloads a new ROM over WiFi. You could upload it to your Google drive and download through the app or just use the internet browser. Then use a file manager like Root Explorer to move the files to the correct location on the SD-Card. Boot it into CWM and flash the new ROM and see if it helps.
Is the stock SE cable???, have you tried with another cable???
I have the same problem with the SE cable, my phone don't connect correctly with my PC, it disconnects automatically or never work...
Actually I'm using a Samsung cable for use the phone with my PC and works perfectly.
Actually u can try to take out the memory card and used card reader to other ROM beside that u used one. Then flash it. see how it going.

[Q] conecting via USB

Hi, I need advice, today I made the root SGS2 and when you want to load custom ROM so I need to get to the phone memory. But since I can not root galaxy connect to it via usb to pc not know what to do? I tried to reinstall the drivers remove kies etc.. nothing ..
Thank you all for your advice.
What?
Aha ..
Sorry for my bad English.
so, again
Today I made a root on my Samsung galaxy s2.
Since then we can not connect the phone to the computer via usb cable.
Because I want to insert a custom ROM, you need to connect to the PC.
Therefore I would like to ask you whether you know what happened? Why can not I connect to PC via USB cable while before we root via usb cable worked.
I tried reinstalling drivers but still nothing.

Don't know about the whole pc-thing, but you can download roms directly to your phone.
And btw, opening two of the same topics is not the way to let people answer your questions faster. Next time just open one thread.

Well if you want to go into usb mode...settings> (under wireless) go into more settings>usb utilities>connect to pc
Then connect your phone to the computer and remember to keep usb debugging off..
Or you can simply take your data in a mmc via card reader and put it into your internal from the mmc...

Hard to tell. Check the device manager. You may need to manually select the driver that the device uses. Also, try another computer.

I am not sure, but have you tried connecting directly to the pc at backside usb? the usb on motherboard? well the symptoms are exactly same when you put on front usb port on pc.
I hope you are using original cable. Sometimes bad and lengthy cables do loss signals and this happens. Voltage passes but not the data making it undetectable. feedback.

Phone not detected by windows 7 help!

Hi guys,
I'm new to this forum. I've got a Samsung i777 on android 2.3.6 kernel 2.6.35.7 build number gingerbread.uckk6
I've recently bought this phone off ebay
My phone does not get detected by windows 7 or Macbook. I've tried changing the USB flex cable with I9100 v2.3 but still no luck.
When I connect USB port it beeps and shows mtp-initialization/mtp-connected on the phone but it is not shown on windows. It says USB cannot recognise the device. I've got a s3 and ideos x3 both of them are detected.
I've installed kies 3 on my laptop.
I had to swtich off the wifi on the phone because it consumes a lot of battery, I think it is because of the android version I'm using!
I want to root the phone and unlock it!!
Any help is appreciated!

I'm guessing the problem is the Samsung drivers you have installed for the s3. Try uninstalling those and installing the correct drivers for s2.

Did you install another ROM? It might help to Wipe system, Data, ETC! it appears to be a software problem. Or at least my guess is the ROM your using.
The Galaxy phones all use the same USB drivers whether it's an S2, S3, S4, etc., so if the installed drivers were working for your S3, it's unlikely to be a driver issue.
Can you boot it into download mode? If you happen to have a USB jig, that's the easiest. Otherwise, power off the phone, unplug the USB cable, hold Vol +/Vol-, then plug in the USB cable. It should go into ODIN download mode. See if Windows detects the phone that way. If so, it very well could be something weird with the OS installed (although it appears to be stock).
If you can get into download mode, you can flash a stock kernel to make sure you are starting fresh. A good file repository is found here. I recommend the stock UCKH7 image I777_UCKH7_OCD_No_BL.7z (you'll also get root).
And yes, the UCKK6 release had a serious bug related to the wifi that could drain your battery. Best to go with UCKH7.
You could also download an app that allows you to enter download mode.

I was able to boot to download mode by holding the vol +/- key and then plugging in the USB cable but there is no movement from the computer it doesn't make a sound nor does it detect. I tried restarting the phone then I get a notification on windows that USB device not recognised!

Are you saying to get a balloon notification in the tray that says the USB device is not recognized? A possible reason for that is a faulty USB cable or USB port (funny enough, I actually got that message last night when I was playing around with my Captivate, and switching USB ports made it work). I know you said you've tried other computers an another USB cable, but that's about my only idea. Maybe there's some debris inside the connector that's messing up the connection.
When you say you changed the "USB flex cable", are you talking about the internal connector and board inside the phone? If so, perhaps the I777 connector board is actually a little different than the I9100 board and causing a compatibility issue.
The bug in UCKK6 related to wifi didn't affect everybody, but it definitely affected a lot of people (based upon reports here).

If you have an SD card, you can download another ROM on that SD card from your computer and then you can install custom recovery (CWM) and then install the ROM from SD card.

First ill run you through the problem I had. Just for reference did you use Mr. Cooks script before flashing Cyanogenmod 11? One of his scripts for cleaning before flashing, actually deletes a certain file, not to keen on which one. What it results in though is not being able to flash OF ROMS and some certain custom ROMS! So id recommend alliance's ROM! As for the "Getting the ROM on your device, you could put the ROM on your SD though recovery "Mount and storage/Mount mass storage/" or just use a micro sd card adapter and move it on there that way.
Thanks for your reply. Would you mind sending me the link on how to do that step by step as mentioned I'm new to Samsung phones and also this forum.

What state is your phone currently in? Is it still not detected by the computer? You are still on 2.3.6, correct?
If it's still not being detected by your computer, I'm not sure if you can flash anything needed using the stock recovery. I know that when I flashed stock JB, I was able to boot into stock recovery and directly apply the standard CWM update file here. It will give boot into a temporary CWM that should allow you to flash other ZIP files (like a ROM), although I had trouble doing that (so I ended up flashing the AJK_v4.9_NoSwap.zip kernel using the MobileOdin android app, which gave a permanent CWM recovery).
I'm not sure if this same process works with the 2.3.6 recovery. However, in order to get the stock recovery to see the internal SD card, I had to run adb shell commands to mount the partition (meaning I had to have a working connection from the computer).
Solved!!!
HI Guys,
Many many thanks for all your responses!
I have changed the USB flex cable again to an older version v2.2 and my phone is currently being detected by kies! So relieved thanks a lot for all your help..now the rooting begins!!:laugh:
