Phone doesnt recognize usb connection - LG Optimus 2x

Hello! I have a big problem. I'm trying to install a new baseband on my o2x but I just can't connect it to my computer. The phone starts charging when i plug the usb to the computer but I just can't enable usb mass storage (the menu never pops up, it only charges). The computer of course does not recognize the phone either. I tried plugging in my old HTC legend and the usb mount worked flawlessly. I'm currently running the MiUI pre release (celebration 2.0) on my o2x but I tried the latest cm nightly aswell as Slick2g-v4 and the problem remained. I installed the LG united drivers, rebooted both phone and computer but still no luck.. Any ideas?
I'm greatful for any help (already seriously considering throwing my phone in a nearby lake and getting a SII -.-)

if youd read the miui thread at development, there is a problem with mass usb connection, usually if your coming from cm, your ext sd is not linked correctly, _extsd something folder from internal, thats why your phone does not recognize your sd card, hence it cant mount

@droweed: Hey Even i'm facing the same problem on Optimus 2x CM7
I understand that the SD is not linked directly dats y its not getting detected..
So can u tell me what can be done or atleast point me in the right direction

Alright : / but shouldn't the phone be able to mount the internal sd at least?

I need stock 2.1 for Captivate

I can get into download mode, recovery mode etc. but since froyo update and one click root/sideloader - no computer recognizes the phone...
no beep - on the pc, no trying to install drivers... it's like its not there, but captivate beeps and knows usb cord is in...
What up? I want to go back to 2.1
Is there another way - like copying the 2.1 files to a micro sd and moving to the root and doing a restore or something?
Help - got to take phone back!

Read the OP in its entirety. You may be able to get by just loading the drivers, but if that fails, you can flash back to stock 2.1 with Odin using the instructions he's listed.
Odin requires connectivity. Drivers installed and worked when I flashed 2.2 - but now its like the phone is not there at all.

Just to cover the bases... are you using the usb cord that came with the phone? I've found that my Captivate won't be recognized if I connect with my wife's HTC cord.
Do you have the SDK tools? If so run and ADB devices command from a command line and let us know if the device shows up.
Reboot the phone and pc before doing this. Make sure the phone is in USB debugging mode also.
isn't there a way to just get the .pkg or update.zip or something that you can put on the micro sd card?
can you flash roms from the card? internal or external?

my samsung cord stopped working 2 weeks after i got the phone, i use my nexus one cord, and while im here at my moms ive been using her bb torch cord, both work perfect.
also a quick note....make sure you don't have any other usb storage devices plugged into your computer....i noticed i would occasionally have this issue if another usb external was plugged in....try another computer also to see if it reads
i have tried on numerous machines

If i am not mistaken there is not a way to return to stock without being connected to a pc. It is odd that no pc will see the phone. Really sounds like a driver issue. Could also be the cord as it has been seen in a few cases that nothing short of the stock cable works, have not had that issue myself but have had no pc see the phone and it turned out to be that I didnt have debugging mode checked and had to reinstall the drivers but then had no issuses.
I ran into this moving from one rom to another. What made it finally work was after selecting your usb mode after the cable is plugged in, I dragged down the notifications and one was click here to mount phone. After I did that it connected up just fine. I was starting to panic as at that point I was on stock eclair, z4root was not findable in the market and it wouldn't let me sideload it from my external sd card. Actually I still had to copy the root.zip from one click root onto my internal and rename it update.zip (essentially what one click root does) and boot into recovery and apply it. Once it was rooted, I was out of the forest, but got nervous.

A little bug wich needs to b solved....
Well Re-installation of another ROM worked for me..
Or Search for this app "Dual Mount SD" or sumthing from da market..install it..
Had the same problem until today, I turned on USB Debugging and it started to work again.
USB only charging
I have completely the same problem. USB on pc still isn't making any sound, only charges the device. Tried to turn on and off usb debugging but nothing.
Had everything ok on nightly 91 but I've switched to 99. Tried to flash back to 91 but the problem persists now.
Anybody with solution for this?
I also have the same problem. My computer only detect the phone as connected but the drive doesn't show. I'm currently using CM7 Nightly 99.. Is there already a fix for this??
in the setting choose unmount sd and quick again check back mount sd. it call typical USB connected screen. there you can choose mass storage like you know from stock rom. this worked for me.
i wasnt able to solve how to connect phone with cm7 to lg pc suite and transfer my contacts to phone. that was reason, because i returned to original rom

Cannot connect to pc

Hey guys,
I have a problem with my Optimus 2x. Recently it couln't read anything from my sd card, every file got corrupted suddenly. I had to format the card again. Now I cant connect phone to any pc, it says that windows wasn't able to install drivers. I've tried it on 3 computers, I even wiped and changed rom from CM7 to MIUI to try. Nothing.
No difference whether I have sdcard in the phone or not.
Any help please?
Okay, after installing drivers from LG it works... and I though usb mass storage should work anyways...

Computer won't recognise O2X in APX-mode

Hi, i'm trying to root my stock LG Optimus 2X v20d Gingerbread with this: http://forum.xda-developers.com/showthread.php?t=1327599
I'm unable to connect to the computer in APX-mode. I tried connecting to the CPU at the front and the back (port on the motherboard) and whenever i tried to connect my Optimus 2X, nothing happens when i pressed both vol up+down when connecting to computer. I've been disconnecting and connecting the USB device over and over again but to no avail. Tried switching out the USB cables also did not work. No prompt to install the drivers appeared. I'm also unable to find any APX-related devices in Device Manager.
I have tried to list hidden devices in Device Manager to check if there's any APX-related drivers too, but still, to no avail.
I'm really out of ideas here. Can anyone help?
[EDIT] To add-on, i previously used MIUI before reverting back to stock froyo and then upgraded to stock gingerbread via LG's update tool. The reason is, my computer won't detect my MIUI in USB storage mode, but i remember that my MIUI'd Optimus 2X did connect to the computer as APX-mode before.
Did you remove the battery first? Won't work unless you do.

Yes i did. I took out everything (battery, sdcard, simcard).
but i remember that my MIUI'd Optimus 2X did connect to the computer as APX-mode before.

This should mean that the APX-driver already is installed, so in theory you should be able to skip step 2.
If however there's no "NVIDIA USB Boot-recovery driver for Mobile devices"-device visible then indeed APX-mode is not recognized.
Just to make sure you can try to do it on another computer and see if that registers an unknown device. If it does not, then well, something is broken.
Problem solved, rooted!
Woah, i nearly gave up until i decided to gave one last try to root this phone today. It worked!
Turns out that the connecting at the front works too (well, at least for me). This time, i only took out the battery (left the simcard/sdcard) in the phone and connected the USB cable to the O2X, and a pop up on APX appeared!

LG Optimus black P970 USB Bricked

Please can someone help me, I have an LG P970 but the USB port seems to be bricked. The phone charges when connected to the computer but nothing else. When connecting the phone to the computer, the computer does not see the phone and the phone does not come up with any usb connection mode.
For this reason I rooted my phone and updated it to the latest version of Zeus rom, but this didn't fix the problem. The phone still just charges on the computer but that's all it does.
I think the phone USB drivers are faulty or need resetting. Is there any software APK I can download to fix my phone.
Thanks for any help.

lol.Man.You reboot intro recovery -> mount and storage -mount usb(you don't unmount).
You must have the phone conected to pc via usb.Then you will able to acces your sd card
To me it seems more like a driver issue more than your phone usb not working, try installing the latest drivers as DaemonOnx said

The problem is that when I go into '>> mounts and storage' the only option available to me is - unmount. There is no 'mount usb option'
By default I select unmount - to which as you say nothing happens.
Happy to try further options if you have any?
Edit - reread OP, response invalid

You most likely have problem with your pc LG drivers.
Download drivers by finding the link for LG driver on this page: http://forum.xda-developers.com/showthread.php?t=1448803
Install the drivers and try connecting and it will work

Hi thanks for this. However, the link to the usb drivers is broken. I have installed the usb drivers from the lg website and I know they work fine because I have now tried connect a friend's LG optimus black to my computer and the computer and phone both recognise each other. So I know it's not the usb cable or usb drivers on the PC. I have also installed the LG usb drivers on my laptop and spare computer, however again I have the same problem - phone only charges.
When this problem initially occured about a year ago I sent the phone back to LG and they did some sort of software refresh, which solved the connection problem for a few months, but then things went back to the way they were. I then thought it may be a PC issue so I downloaded drivers and connected my phone to the laptop and everything worked well. However, again, a few weeks later, things reverted back to the same problem. The phone only charges on both PC and laptop now.
Hope you can understand my frustration.

LG service center? you've pretty much tried all I would've
Last time I took the phone there, I was told it might have been the phone port software corrupted. Whatever that mean. If I can't find a fix to this I will need to somehow unroot the phone and try to get it back in its unrooted state to LG (not sure if that is possible) else they probably won't fix it.
I'll keep looking,
thanks for your help.
You are using the the proper usb cord. I know I have a couple. The one will charge only.
Yes I am using original cables, I have three of them. They all work on my Friend's OB but not on mine. I am convinced it's a phone software issue. This has happened with three different computers - when you first install LG software on the computer, the phone connects okay for a few weeks and then loses connection, and I can never get it connected again.
When LG refreshed the phone software for me the phone worked properly for a little while and then reverted back to charging mode only.
I need a way of reinstalling the USB software or port software onto the phone itself via some type of APK if such a thing exists.
Maybe a developer here can develop one???
hey man
if you have disabled the "android platform usb modem" in peripherals manager, enable it first (phone must be plugged)

this means it must be the result of an intervention by a third party thing, by yourself, or another program. If you have a kind of a software which manages ports or consumption (on phone as well as on Win), uninstall them, then uninstall all LG drivers, reboot, then reinstall them. if that doesn't solve your issue, you may have to reinstall windows. that's radical, but it should do it
Try connecting the usb while doing pressure between the LG logo on screen and the back of the phone, like squeezing something . I had this issue and it was an internal connector issue....
Check if you hear the "tada" sound in windows or any message about a new device.

Hi, thanks for this, I'm not sure what you mean by "disabled the "android platform usb modem" in peripherals manager". I am using XP. I have had a look to see if there is any software remotely associated with port consumption etc and have uninstalled these and also reinstalled LG drivers. But situation is still the same.
Please note: I have an LG GT540 and this connects fine to the computer. I have also connected another LG optimus black and this also connects fine to the computer. On the basis of deduction, it must be a phone issue, somehow interacts with the computer fine and then fails after a little while. Also I haven't installed anything on the phone itself which might manage consumption or port. The computer has a usb host controller but not sure that means anything useful.
I do agree and have feeling that if I reinstall windows I bet the phone would start working again, possibly again for a few months. This means I reinstall windows on my pc and laptop and hope it all resolves without actually getting to the bottom of the problem.
What I need is another laptop to try this on. If I try another computer or laptop and it recognises the phone. What do I make of everything??? Any ideas.
ps also tried holding pinching usb lg cable as suggested but nothing different.
Thanks for all your efforts.
Further update to this, I installed LG drivers on a fresh dell laptop. Again nothing happened, the phone only charges. I am even more convinced that phone software is corrupt. How do I reinitialise phone USB software?? If there is such a thing.
