It's not recognized when the phone is on? Seeing as you posted this topic using your phone I assume so lol. Have you tried restarting your computer?
You can download the correct drivers here.

Make sure you are using the oem usb cable. I had the same problem, changed cables and it worked
some cheap cables are for charging ... bt headsets and other stuff the data cables dont connect, its just for power.

You gotta make sure that your usb port is directly connected to your motherboard (usually back of your computer).
same usb port that has always worked. ive tried them all by now anyway

Duno what happened but I'm glad it worked out for you
I'm having the same problem with my captivate after flashing REDROM. It won't recognize it if I have USB debugging turned on...
i have a theory... were you on a GB or other i9000 based rom/kernel???
well, im still having a problem getting my computer to recognize the phone, i have to mess with it for a a while to get it to work. i really want to flash anew 2.3.3 rom but without being able to get everything working right im stuck in 2.1
is this a problem with my cord or the connection on my phone? or something weird with my phone after flashing it a lot. its currently back to odin stock, i have been trying to master clear it with no luck

continiuum miui and cyanogen mod are the only things ive tried to flash
well it looks like i'm done. my phone will not show up on my computer and its currently bricked, although i have no issue getting it to download mode i cant do anything with it. unless someone knows some magic, looks like im downgrading to my gf's 4 year old busted up BB
Guys, this problem while connecting to the PC body is stupidly charging .... Even in the download mode Odin does not see a body that could be? Connect other Cappy-all OK.

it must be a powered usb hub, on my buddies laptop only 1 out of 4 usb ports saw his phone.
if you can get into download mode you arent bricked.
try installing i9000 drivers, or try another computer.
I came up with this a while back. Could very well be the same issue.
Let me start by saying I'm flash happy, and everyone that knows me personally, tells me to just quit jacking with my phone. NOT A CHANCE! I'm on my 3rd Cappy and shouldn't have ever exchange it again. I only had to in the beginning, because I was a newbie and had not know enough, but to get me in trouble.
I presume that this should work on all Windows OS's. I personally am running Vista Enterprise x86.
My symptoms:
Plug in phone to the usb and it there was about a 15% chance off being able to mount to usb, and Windows recognizing as a mass storage device. I tried un-installing drivers and re-installing and it would work some of the time, until the point came when parts of the driver install would fail. Then to the point when it was just completely unrecognizable. I thought I had it fixed because it seemed intermittent. In the middle of flashing to stock, something interrupted communication between the pc and my phone. Restarted the phone and attempted the flash again. Got a little farther and froze again. I had to use another pc that I had never connected my phone to before and I was able to use my jig to trigger download mode, because no buttons combinations would allow it into download mode.
This got me thinking that it was specific to my pc and not my cable or my phone.
My resolution:
I went straight to the registry and went to find. I deleted every entry that came up for "i897" and "i9000" excluding what was listed in the system volume information, as I didn't have permissions to remove any keys. I didn't keep count, but I probably deleted 300-400 registry keys that pointed to my phone. It seems as if with each developers rom that I had flashed, there was an entry for a different device. Don't quote me on that, because it is just my personal consensus. I also un-installed the samsung drivers, the unknown device driver, kies software, and anything associated with samsung. I noticed that next to all of the i9000 instances, the hex key for me started with 1000ee. So I also searched for the first part of that key trying to ensure that all instances of the device. Lastly, I deleted the samsung folder from program files.
I installed the samsung drivers package commonly listed in all of the other threads for x86 operating systems. I plugged in my phone and watched as each and every driver installed successfully. Keep in mind different drivers are installed depending on if you have usb debugging on/off, and the options for if the preferences on you phone are set to media, storage, or kies. I have multiple usb ports, however testing has shown me that, for me and my setup, I can plug into the port that I used when installing the drivers the final time, I am able to connect consistently. Earlier today, I tried to plug into a different usb port and it was an unknown device. I am led to believe, this is because I didn't un-install the unknown device on this particular port.
If you intend to work in the registry, please remember to always back it up first. You can always restore.
Hopefully my findings can help you as they did me. Happy flashing and I would like to thank the community for the dedication to assisting each other and the developers, for making flashing, better than crack cocaine. Flashing rom's doesn't make you twitch near as much as a crackhead.
Well since you can't use your phone you should sell it to me

Hi,
I currently encounter a problem with my Optimus 2X.
I can use my usb port to load the phone but when I plug it in a computer (I tried with several computers running XP / seven / ubuntu ... and several cables). But my phone doesn't seems to be recognized by the computers.
I'm running 2.6.32.45 cyanogenmod. I wanted to go back to the original rom but my backup seems corrupted
Does anywone knows how I can go back to the original rom ? (hopping it will fix my usb issue ....)
regards.
Uninstall the old drivers, and download v3.6 from lg's site it has fixed this issue. =P

Thank's a lot it works perfectly !
I now encounter a new problem, when I try to update my phone using the LG software, it stops at about 30% (looks like it's impossible to connect the phone with the software).
Edit -> I've found an old stock rom and installed it on my phone : everything works perfectly thanks a lot !!!
Guys
I'm running CM Nightlies and I can no longer connect my phone to any pc via USB.
Some have said I would have to flash phone back to an original rom in order to fix then flash CM back over it?
Is this really only way as worried will lose all my internal drive stuff.
You can try to change your drivers it works very well !
If you wan to save your stuff without using USB you can use FTP thrue à WIFI to send stuff on your PC.
I got the same problem since about 4 months. When connecting the phone to the computer, no usb icon appears on the notification bar, also there is nothing happening in the device manager on the computer. Charging always works.
This is still confirmed after using different computers, different usb cables, different usb ports, and 4 different versions of the drivers (up to the most recent 3.6 drivers) even it should still show something even with no drivers. This also occurs in "software update" mode.
Also I tried different ways of plugging in the cable on the phone side (slow, fast, with pressure up/down/side).
This is with CM7, CM9alpha, and just for test also with MIUI.
The odd thing is, in this time span, it randomly worked about 4 times in these 4 months. Last time was just after I updated to CM9 alpha it worked the first time I plugged it in (was surprised with that), but it stopped working too.
For me it seems it's something with the usb chip set in the phone.
The problem here is, returning the phone for RMA will cause problems with CM on the phone, as they probably will say it's because of a custom rom, and there is no (easy) way to get stock rom with branding back on the phone (the only one maybe with a nandroid backup of stock from someone else?).
I'm having the same trouble as dedors. Absolutely no USB data connection. Can't get anything going in nvflash, smart flash, recovery, or when running normally. I've tried uninstall and reinstall the drivers, multiple cables, multiple computers, multiple OS including win7 xp and Ubuntu. USB debugging enabled, disabled, wiping the SD cards, trying with no external sd card. The only glimmer I've seen of it working was when I plugged it into my old XP laptop before and it prompted the computer to install a driver for the webcam that I'd mistakenly uninstalled. I tried cleaning out the USB port in case it had a bunch of lint stuck in it and the cable just wasn't sitting properly.
I don't know at what point it stopped working but it has had no serious abuse that could cause any physical damage.
Oddly it still charges just fine.
Can't return for RMA as it's running Cyanogen 9 and I've no easy way to get it back to stock. I also had this problem on Cyanogen 7. I could probably flash a stock rom onto the phone but I wouldn't be able to nvflash the original recovery.
A lot of people seem to have had USB trouble with this phone.
Happy to provide any logs that may help the diagnosis though you may have to explain how I can acquire them as I only know basic flashing.
Sorry for the lengthy first post, trying to be thorough.
Thanks in advance for any help offered.
I can't think of any solution to your problem (in my opinion it seems like a faulty USB port, it seems to be "popular"), but I can suggest you a workaround... it's actually the workaround I've been using cuz I also have trouble with USB... get an SD card and a USB to SD card adapter...
Or that ftp/wireless trick that was mentioned above, I actually don't know how to do this but I would definitely like to
Yeah that does seem to be the case. At least I can still flash roms and so on. So long as it lasts me the rest of the year I don't mind grabbing a new one then.
Anyone who knows about logs for trouble shooting, can you suggest a way that I might try to diagnose the problem. If I can be sure the port is stuffed and nothing I can do will fix it I'm ok with that but I'd like to know whether I should keep looking for solutions or give up on it.
Cheers.
Hello,
I've got a new issue with my phone updating CM10 and today it's impossible to boot.
I've tried to plug it on my computer in order to flash it but got the same probleme as the first post : nothing happened when plugged on my computers.
Does anyone got this 3.6 drivers somewhere ? seems that the new ones from LG didn't works ....
I have the same problem
I how bought my phone (LG P990), 6 months old, used. I come home and try to connect it to the computer and it won't be recognized. Somehow I manage over that code 1809 # * 990 # to enter the menu and play with the ports I was able to connect to the computer and do the official update to 2.3.4. over LG software.Once again, this comp will not recognize phone (only charging), but using code 1809 # * 990 # and tampering on port settings it was able to connect to the computer.
Now after some time do stupidity and Root my mobile phone(SuperOneClick) and install clockwork-5.0.0.3 and via zip CyanogenMod 9. I tried all the ways that exist but pc does not recognize the phone anymore. After some time, the official ICS update is coming, and now that you can not connect the comp how to update mobile phone. I do a recovery back to the official Android 2.3.4 (I had to change the partitions, 2.3.4 and ICS use different sized partitions) and I run a mobile phone that is again official 2.3.4 and try entering the menu (1809 # * 990 #) by tampering with ports settings I tried to make comp to recognize the phone but to no avail. I tried to change the usb cable, use a different USB port on comp but nothing, no response just recharging.
After googling I managed to find recovery from ICS V28g and I managed to install it to have a functional phone. I contacted 2 service both refused to accept phone because rooted. I tried all the tricks without battery holding vol + and - to enter into APX mode, nothing then Power and vol - S / W mode that worked but comp ga would not recognize until now even that does not work (appears LG logo and when S / W should appear then goes off) and all the other tricks that I found on the internet, reinstall the drivers, I do not know what else.
Oh yeah and I noticed entering the settings on mobu System Settings / About Phone / Software Information / Baseband version - unknown

Hi,
I've found an old 3.6 driver, but nothing works even with it ... I think I must change my phone -_-
Ok guys I'm a noob around here. I've had my P990 for about 7 months and I'm ready to throw it against the wall:crying: I've been searching for info on this type of fault and I read that it happens pretty often. I really didn't have the need to plug my phone to my computer, so I never did, until about two days ago I decided I was bored with my stock phone and decided to install the latest version of android, so I downloaded the LG IV suite. Installed it, I'm following the directions, connect my phone and bam, NOTHING I kept getting an error on the LG suite, can't find phone, check connection and try again. At this time I also notices that my phone was charging through the USB cable. So my basic troubleshooting techniques kicked in, and performed the basic steps:
-Made sure Mass storage only box is checked
-Switched USB cable
-Re-installed the driver
-Downloaded the latest driver from LG website
-Downloaded drivers recommended by XDA
-Tried two other computers with two different OS
So none of this worked:crying:
After monkeying around for a couple of hours with my phone, I read somewhere on this forum to take out the battery, connect to USB cable to your computer, hold down the power and volume down buttons at the same time, this would put my phone in some mode, I don't know what that mode is, but decided to do it. My phone powers up, then I see the green android little man with a white box and an arrow coming out of the box. Ok, finish doing it's thing and then it reboots. I go into my phone and find that everything has been erased and the phone was back to it's original state when I received it over the mail.
Since my phone is back to stock, I decided to go the root road. Downloaded SuperOneClick, installed it connect my phone via USB and I'm back to step one. I get nothing!!! So then I decide to go the root flash road. So I downloaded the z4root adk file and put in the flash, pop the flash in my phone and nothing. Can't see my flash card on my phone (never used an SD card on my phone and decided to buy one for this instance). Kept reading on-line and found that I need a file manager application, so I installed Linda Manager on phone, opened the z4root adk file and installed on my phone. So now I'm getting very excited and I'm giggling like a school girl because I'm starting to see light at the end of the tunnel. So I run the z4root application and go with permanent selection, the application start the root, then BAMMMMMMM. The application just stops and my phone takes me to my home page. I decide to restart the z4root application and I can't get the app to run. I re-booted my phone, restarted the app, and keep getting stuck. The app stops and I can't never successfully get a root. I'm out of ideas, I've going at it with my phone for two day and reading on the net.
The two thing I want to accomplish is to be able to use my phone via the USB cable and to root my phone. Can you guys point me in the right direction. At this point I'm willing to try anything on my phone since everything got erased.
by the way here's is what stock I'm running on my phone:
Android version: 2.2.2
Baseband version: 1035.21_20110725
Kernel version: 2.6.32.9
Built number: FRG83G
LGE version: LGP990-V10d
My computer is running Windows Vista, I also tried a Window 7 and a Windows XP computer and still nothing for the USB.
I would appreciate any help guys, throw me a bone over here:laugh:
Same thing happened to my friend. No USB detection (the phone was charging through usb but nothing showed up on the pc). He tried everything then he called me (I have o2x too) , i tried everything you did too. His pc detected my o2x , but when he connected his (on the same cable) ... nothing .
Finally he remembered the phone had warranty and took it to tech suppport. First they reflashed it , but when he tried it home ... nothing . He took it to support again , they kept it for about 10 days and told him they had to change the motherboard.
Phone works now.
He was on stock froyo too , Vodafone Romania version.

Sorry for the bump, but I got some update.
when dialing the above mentioned 1809#*990# in the Port menu, switching from default AP USB to AP/CP UART gave me life signs.
After switching to AP UART I linked the Unknown device driver to lgusbdiag.inf located in C:/ProgramFiles(x86)/LG United Mobile Driver.
Suddenly it started installing it and is now recognized as: LGE Platform Android USB Device.
Once disconnected I lose USB again, I'm able to recreate the first steps though even in default AP USB mode by now.
The only thing I need USB for is for flashing a custom recovery but the only thing I don't have is ADB somehow : / Clockwork telling me: device not found.
Any help on this one?

I get the exact same symptom, as soon as I change from AP USB to AP/CP UART, my battery icon on my phone goes to charging, without the being plugged in
Well I'm pretty tired of monkeying around with this phone, but I really like phone and really don't want to change model. So I decided to order a brand new one:laugh:
I should be getting it within the next two week, hopefully that doesn't give me the same problem
I'll keep you guys updated.
Help??
A very good friend of us noobs toying with our O2x's are Paul O'Brien.
I could not get any other flashing tool to root my O2X other than his. Here is link to his guide:
modaco.com/topic/335474-25-mar-nvflash-stock-rom-release-v10b-dated-1300166062-15032011/#entry1645587
He also has the tool to completely restore your O2X back to factory standards, and in the O2X forum here you will find all the different stock roms, you need to get your phone back to these factory standards and restore your warranty.
After you flashed your phone and get ready to try all the marvellous ROMs, waiting on the other side, I can only recommend to purchase the PRO version of Clock Work Mod, it really brings out the fun in rooting your phone.
Seeing your description of your troubles, I think you have softwareproblems, more than hardware problems, so a complete flash and maybe restore, will likely solve many if not all of your problems.
Best regards
Mike
And dont forget to show your support to the developers, they do a marvellous job for us!!!
Thanks mike,
I followed the link you provided and did a lot of reading. So decided to try that method. No luck with that, my computer doesn't detect APX mode while holding down both volume keys. I tried it like 10 times every time holding the keys at different intervals. I even tried it on my wife's laptop running windows 7, didn't work either.
I did find a lot of good info on the link you posted.
Thanks, just waiting on my new O2x to come in the mail.
Possible solution
Some days ago, I also had a problem connecting my LG Optimus 2X to my PC (Windows 7).
I solved my problem using this instructions I found in the G2X forum, by conspirator_boff user (http://forum.xda-developers.com/showpost.php?p=15899923&postcount=10)
Similar issue. This worked for me on Win 7.
Uninstall the LG Drivers and reinstall the G2x 2.2 package from LG.COM /us/support/mc-support/mobile-phone-support.jsp (I can't post links)
Plug the phone in and go to Device Manager. There should be a USB Composite Device that is not properly installed. Right click it and select Update Driver Software.
Select 'Browse my computer', then 'Let me pick'. Choose have disk, and browse to where the LG Drivers are installed. Likely C:\Program Files\LG Electronics\LG United Mobile Driver\ and select lgbus9x.inf.
Then pick LGE Android Platform Composite USB Device from the list of drivers. Should be the top option. Hit next.
I let it sit for a minute while the drivers installed. Some things registered in device manager right away, the LGE USB Modem for one. But, the drives didn't. Unplugged the phone, plugged it back in, and the drives popped up under Portable Devices.

I think it's an issue from the newest LG Drivers because when I first tried to connect it a year ago I had no problems.
Hope it helps.

Good luck and I hope your new phone will behave properly.
Remember Paul also has tools for bringing your phone back to factory standards, so you keep your warranty.:good:
Enough said, good luck and remember our O2X is probably one of the easiest phones to try out different ROMs at and I have never enjoyed this little gadget as much as after I flashed it!!:

Fixed
Sorry guys for the late update.
I received my new P990 about two weeks ago. As soon I pluged the phone into my computer it started installing the drivers and I was able to use my phone via the USB cable. Another thing I noticed, on this new phone when I pluged the USB cable, I noticed it went in nice and firm, on my old phone the cable seemed to be a little loose. Anyway it was definately a hardware issue with my phone. I'm pretty happy with 2x.
Ok Guys, I started this thread because last weekend I had an interesting issue with my O2X. From one day to another, whenever I connected my phone to the computer it only charged, I had no USB connection. I’m not yet quite sure why it happened, the last thing I did to my phone was install CM10 nightly of 31 October 2012, and then I changed the default baseband I had (725) to the one GetRil was telling me to install (LGP990AT-00-V20l-EUR-XX-OCT-20-2011 0_CP) (this baseband didn’t fixed the strange noises of in call) two days after that I got the no USB bug, at first I thought it was software related, then after lots of reading and trying different cables and computers I thought it was hardware related, but then I saw an interesting chance of fixing it, and it did in my case
Credit goes to Kohos, I manage to have USB fixed temporary thanks to his post on modaco.com
I’M NOT TELLING THAT CM10 CAUSE THIS BUG, IT JUST HAPPENED TO ME WHILE USING THIS ROM
Specs
Phone: Optimus 2x (p990H made in south Korea)
Rom: CM10 Oct 31 2012 (when got the bug) now CM7 nightly 15 July 2012
Kernel: Symbiosis 2.6.32.59 v1.2
Carrier: Telcel
Country: México
Ril: 0725 (V10d, Europe)
BB: 1035.21_20110725
CWM: 5.0.2.0 (no touch version)
To solve this issue you need to have a stock ROM that can be flashed by CWM. Can be the rom, or a backup of the stock rom (If you don’t have one send me a PM), I didn’t tried stock-based ROM so those may or may not work; I’m not sure but rather use an original stock ROM. You also need to be able to enter CWM recovery, and have LGE drivers up to date.
For this method I used a stock nandroid backup.
I’ll describe step by step all I did to solve this issue so you can give it a shot:
1. If you have a flashable stock rom you may skip this step and go to step 3, if what you have is a nand backup you need to make your partitions back from EXT4 to EXT3 (this is the format that stock rom uses) so need to download the tool R2 found on the first post here:
http://forum.xda-developers.com/showthread.php?t=1021549
put it on your external SD card along with the backup of the stock rom
2. Reboot to enter CWM recovery and install the tool R2 (NOTE: this will erase all information of the internal memory)
3. Install or flash your stock rom or backup (In case you're using my backup, keep in mind, my file IS NOT a flashable rom, it is a backup, so trying to use the option "flash zip from external sd card" WON'T work, what you need to do is unzip the file and put it on sdcard/clockworkmod/bakcup, then on the recovery, you have to use the option "restore from external sd card", that way it should work, keep in mind that if you change the name of the file it will give md5 error for the name won't match the backup's md5)
4. Reboot and start the phone, once it is all loaded, on the phone app dial: 1809#*990# this will take you to the service (hidden) menu (If it doesn’t take you automatically to the service menu (without clicking dial) you’ll need another ROM or backup)
5. In this menu you’ll need to scroll to the option: Module Test > USB Mode Selection, in there make sure the option LG Android USB is selected
6. Then go back to the root of the hidden menu, and go to Port settings, there you’ll see several options, the ones we’re interested in are: AP USB, CP USB, AP UART, CP UART, the default should be AP USB, you can start playing with those options. (While doing this, you might want to play with your computer device manager scanning for hardware changes, that might help detecting the USB)
The recommendation is to select CP UART, wait, if your problem is not hardware related, it should popup a message of new unknown device, or LGE Platfrom Android USB device. If your USB show some life signal, then you’re almost done, if not, keep playing with the four options until you see some life signal.
What I did was select CP UART, click Ok, wait, AP UART, click OK, wait, CP USB, click OK, wait, AP USB, click OK, I waited here about 1 min, and then on the computer device manager I scanned for hardware changes, and suddenly my computer started installing all drivers again, this last option is the one that must keep selected even with reboot of the phone.
7. Once you get all done, reboot the phone and connect it to USB to see if it is recognized again, if not, repeat steps 4 to 6
8. Ok, If everything went fine, you should now have USB connection, now I would recommend you flash your Stock Rom, so everything that might cause this bug gets fixed (if you don’t do this, you might get the bug back eventually). To do so you might need to turn off your phone and plug it to your computer while clicking PWR and VOl- at the same time, if your computer doesn’t recognize your phone, use the device manager and scan for hardware changes, this should reinstall the driver needed to make this happen.
9. Finally I restored my last nandroid backup through cwm
I did this on Monday, and two days later I had no USB connection again, I repeated this steps and I had USB detection once more, today it happended again, and repeated the steps so I’m pretty sure this fix should work every time.
NOTE: This is a temporary fix, I've been trying to identify why the bug keeps comming back
Hope this help you all get over this serious bug :laugh:

Ok, guys I told you I would make some test to make sure the bug won't come back or identify the problem, what I've found so far is that the problem might be caused by the wall charger (but might not the the only reason), If I'm not wrong, the LG stock charger has output of 5.2V - 650mA DC and I've been using a motorola charger (5.1V - 850mA DC output).
Four days ago I started charging my phone only with my computer (usb port has output of 5V - 500mA) and I've had no trouble at all, the bug hadn't come back, today I charged my phone with the wall charger and the bug immediately came back, so for now that's my theory, the wall charger, stock or not, might fail and deliver more current that the O2X need so it mess the phone, I'm going to make fix on my charger to prove my theory, (I have no money for a new charger xD, but I'm studying electronics) if it fix it, I'll let you know, but you can try and charge your O2X with your computer for a day or two to help me prove my theory or prove me wrong
UPDATE:
It's been some time since I last posted here, I've been busy with my finals, but have had some time to make some tests to my phone. On my last update I told you that I had a theory about the bug, well, so far I can tell you that the wall charger indeed have something to do with the bug, but its not the cause of it, I've been using my wall charger letting my phone connected all-night long and the bug seems to happen again, but letting my phone connected to the PC for a while allows the USB sync and debugging again, so I'm not sure why it happens, I'm about to finish my finals so I'll try to make some tests once I'm done, hope this giude help you
UPDATE:
Well, as I was testing my theory, I go back to zero, this is because, my phone, doesn't have the bug anymore, so I have no chance to keep testing solutions for it, the conclusion I got with this is that the wall charger doesn't create the bug, maybe it triggers it, but not always nor on every device because, I haven't sopped using the same wall charger and the bug haven't returned, the last thing I did was, use my computer to charge my phone for three days, always letting it charge to 100% (unless I have to move from the computer) and the bug didn't happened, then, on a rush I had to use the wall charger, the bug appeared instantly, and then keep charging it with the same charger, two days after that, the bug dissappeared, I made no rom change, nor baseband, nor ril, nor anything, just like that it disappeared, so, I have no way to keep testing, if it ever comes back, I'll make some tests again, but for now, I have nothing to work with, hope this thread help you to get over this bug, at least, for a while, I'll be reading this thread in case you have some trouble with the instructions or so, cheers
UPDATE:
Ok, so I deleted long ago the last backup you told me was not working, and since I went to CM10 from Pengus I haven't had the no USB bug, so, one person asked me for the backup, I just made a new one, (this one is 204 MB on zip, read step 3) and uploaded it to 4Shared and Dropbox, so, remember to read and follow the instructions as they are, hope this time you can restore this backup, and one more thing, this backup was made just after installing it on the phone, so it doesn't have even a gmail account, you have to put yours and update market if you need something from there, ps. dont mind the date of the name of the file, it is innacurate, cheers
I don't have any stock ROM backup that I can flash via CWM, can I use this instead?

To be honest I don't see a big difference to my post you probably found while searching except that your version is waaaaay more to read.

when dialing the above mentioned 1809#*990# in the Port menu, switching from default AP USB to AP/CP UART gave me life signs.
After switching to AP UART I linked the Unknown device driver to lgusbdiag.inf located in C:/ProgramFiles(x86)/LG United Mobile Driver.
Suddenly it started installing it and is now recognized as: LGE Platform Android USB Device.
Once disconnected I lose USB again, I'm able to recreate the first steps though even in default AP USB mode by now.

But that aside I hope you realize that this is not a solving fix at all. All it does is giving people who got a fresh device the chance to flash a custom recovery. That's all. It won't work with any CM ROM and even Stock based ROMs.
Unless you have an early Froyo version flashed you will also have no ADB and it won't be recognized during the NVFlash process rendering it pretty much useless.
Having seen dozens of people having this particular problem where all the super obvious stuff like other cables, other pcs, other drivers etc. did not work, sending it to repair was the only fix I heard of solving this problem to date.
Of course I'm very curious on how you are going to identify the problem. Good luck.

I'm extremely sorry, there's one think I missed, give you credit (fixing that right away), I actually found your post on modaco.com, and tried to access to the hidden menu from CM7 with no success, fortunately, I do have an early froyo backup that can be flashed through CWM, the only thing is that is the Telcel stock rom (I don't know if this can work with other O2X devices, I think there should not be problem at all)
About ADB, it work in full with the latest drivers installed and scanning for hardware changes on the computer device manager, It even work entering the S/W update service on the phone (to install a stock rom)
I know that many people have had this issue, I spent a lot of time reading forums and stuff about it, the only post that actually helped me, was yours, so, credit is yours, I did this post to show people what I excactly did (that's why is a lot to read, but I wanted to make it as easy as possible to follow up)
To identify the problem is a long and slow task, so, I'll be making some tests and let you know what I found, right now I have no much time, 'cuz I'm about to start my final exams, so I'll be busy, but as soon as I finish I'll be more dedicated to it, I'll be making hardware and software tests but can't promise anything yet

I tried to use that ROM, but couldn't manage to download it (I think it was removed, if you want to give it a shot try to find another flashable stock rom or backup, if not, give me some hours to clean my bakcup and upload it somewhere to let you use it, (it is mexico's telcel stock rom, but it should work)
Well Thanks ocr66 for this wonderfull news. I have the issue with usb connection from long time and i will give a try to your fix. You can post a stock rom here or a link to a rom that works??? In order to instal this fix i could lose the root??? Thank you 4 all!

It all depends on what you install, if you manage to install stock rom through CWM or another recovery, yes you will loose root, but will have usb connection so you can root again, later today I'll upload my own froyo stock backup (it's mexican stock for telcel carrier, i think it should work out of méxico, maybe could cause network trouble on other countries, but its just a posibility, the important thing is that you be able to access the hidden menu), this backup I'll upload can be installed through cwm and its already rooted, so its like installing any custom rom, you'll keep your recovery and root
Remember, this is a temporary fix yet 'cuz I still get the bug comming back, maybe its because I am restoring my last working cwm backup, the only thing I haven't tried is clean all, install stock, root, install custom rom, and download again everything, maybe the bug is caused by something on that last cwm backup
I'll let you know as soon as I upload my bakcup
cheers
Well thank you! How i have this issue from one year i learned to live with her, but i could not live without root. So if i will instal a stock rom without root i will be unable to correct the usb connection i will get stuck with stock rom and no root. Will be the end of my phone. In am interesed to gain the usb connection for change the bb, i supose i can be something wrong with my bb 1035.21_20110725 and gingerbread. You can check to change the bb to see if you get again losing usb connection. Cheers and thank you 4 all.
got this after CM10 install
I've only had my phone for 1 day from new and already got this problem.
Rooted with superoneclick
Installed CWM v5.x
Installed CM10 Nightly Nov 13th
Now no USB mode, only charging.
baseband: v10e
RIL: CM10 1106
EDIT UPDATE: Well its working for me again now, I think in my case it was because I was using Linux and CM10.
By going to Settings/Storage then pressing menu button and selecting 'USB computer connection' I was able to change the 'Connect as' option from MTP to Mass storage and it now works.
@tiktok1 Lucky you!!!
@ocr66 Any news about this bug???

Actually yes, I've managed to identify what's triggering the bug at least in my phone, so might be the same for others as well, see the second post
BTW, did you tried already the fix? did you used my stock froyo backup?, if it didn't work, I can make another and upload it
Hi. Looks like I have the same problem with USB as you. Your theory about the wall charger might be correct. Here's my situation:
So, I've got my phone two days ago, bought used, came with a general Sony Ericsson USB charger. It says it outs 850mA at 5.0V (confirmed with a multimeter). The phone is on stock Android 2.2.2, isn't rooted yet. The guy from who I got the phone says that he suffered too with this kind of problem, however he got it working after 2 weeks without the use of the hidden menu. This means, that in those 2 weeks, he might have used a PC or a laptop to charge the phone. I tried the hidden menu port settings, however the only "working" mode is AP UART, but it is not recognizable by the PC, even if I try to link the LG drivers manually. Cycling through the modes did not help. I'll try to charge the phone with my PC, and see if that dose anything.
Details of the phone:
Firmware version: 2.2.2
Baseband: 1035.21_20110218
Kernel: 2.6.32.9-dirty
Build: FRG83G
LGE Version: LGEP990-V10b
Wow. All i can say is wow! Gosh! Just dunno how grateful I am stumbling upon this thread! Kudos to you sir,you just ended my 2 month long frustration about my phone not being able to communicate to my PC. was getting ready to send the phone for service then I read this. I had flashed every GB ROM imaginable from the dev thread with no luck. I am running carburano DM 1.7 now,all I did was to go to the hidden menu,switched one port setting,wait,then voila! PC recognized my phone! Again thanks,great respect to you,and Superskill.
Hi, this is my post to thebgeneral board by accident, didnt even read there was a qanda section lol
It didn't work on my gfs phone unfortunately, notvsure what was wrong.
Maybe I should try stock Rom instead of modded, how long are you guys waiting for the phone to show up?
I downloaded a stock Rom that had been modded.
So I could be sure that I would have cwm in case anything went wrong.
Rom loaded and was able to get into the secret menu.
I will say that under USB connection type there was misspelling where it said:
LG USB adnroid
Not sure if that would affect it.
I selected that item.
Then went to port.
Selected the different options in ordered and waited about 10 seconds on each turn, then pressed find any changes in device manager unplugged and plugged the USB.
Then tried in different orders but with not luck.
Took the battery out and tried holing the vol up down the plugging in USB but to no avail.
Then pressed power and vol down.
The phone tuned on and showed LG sign then switched off.
I tried pressing check any changes as the LG sign came on but nothing.
Then tried nvflash as the LG sign came on but nvflash showed no connection.
Very weird, definitely dead but still charges, doesn't make sense.
Oh well
Ordered an atrix with work and play kit for 68 quid, has a broken digitizer which will cost 20 pound, on average, off ebay.
Thanks for the help though.
May take the 2x apart when new phone comes and see if there's any physical damage on te board.

No luck...
I've used my PC for charging for a week now, still no USB connectivity. I think this might be a hardware issue with me as the phone sometimes says it's charging, but it's actually in my hands with no cable attached. I managed to root the stock 2.2.2 firmware with GingerBreak and installed CM7 with RomManager with a downloaded ZIP on the SD card. Thanks for the tips anyways.

Hello, I'm sorry it took me a while to answer, I've been busy with my finals, did you tired the tutorial I posted? the hidden menu modification? I know that you let your phone charging for a while with your pc, actually, it should've worked but, maybe the problem on your phone actually is something else, 'cuz I haven't had that issue that the phone says it is charging but its not connected to the charger, my brother told me that he have had that same issue but with other phone, he changed the wall charger and that "fixed" it, but I think if you haven't tried the tutorial, give it a shot, try changing to CP UART if your phone's usb is working as it should, your computer should detect a new unknown device, if not, myabe your phone is hardware damaged, hope you can fix your phone soon
cheers

What I did on my phone is exactly what I posted, if your computer haven't detected your phone on CP UART I doubt rebooting will make a change, anyways the most important thing to see if your usb is damaged or not is to try on the hidden menu the option CP UART it almost instantly detect the device, but, not everytime, I once waited there 20 min, so, give it a shot if you want, the stock rom I posted (on second post) is Mexico's Telcel stock rom, rooted, it doesn't delete your cwm recovery nor root, you can give it a try if you want, but read the instructions 'cuz you have to restore the ext3 format of your phone's partition to make it work (it stays on boot loop if you don't restore ext3 format), if the backup doesn't work, let me know to upload a new backup, hope you can fix it

Hi there, honored experts!
Today I got my precious Optimus Speed bricked, after I successfully restored a recent nandroid backup.
I've been happily running paranoid android for the last months, and often updated the phone with the help of goo.im manager. Today I did a full factory-reset after the CWM upgrade-process, to get rid of the old "disappearing keyboard"-bug. I backed up all my apps and data with superbackup and titanium-backup, and even created an online nandroid-backup (freshly updated nandroid-scripts and patch for my device).
After the reset I had issues to restore everything, since ti-backup often got stuck in batch-restore-processes. Because I couldn't stop the stuck process, it required me to soft-reboot the device a few times. And in the end, it failed to boot.
So I went into CWM, and restored my nandroid-backup. This went fine, and no errors were reported. But after soft-rebooting it, it only showed the LG-Logo-Screen, and nothing else happened. So I tried to get back into CWM - with no luck .
I've tried every possible key-combination I could find, and the only mode I can bring my device into is "S/W Upgrade". In this mode it is recognized by my laptop (running Linux), but rustys recovery fails, because nvflash reports:
Code:
sh ./flash-recovery-ext.sh
Nvflash started
USB device not found
even though lsusb shows:
Code:
# lsusb
Bus 001 Device 017: ID 1004:6000 LG Electronics, Inc. KU330/KU990/VX4400/VX6000
I'm fresh out of ideas - maybe one of you can help me out? Otherwise the only thing I could try now is to turn it back in where I bought it.
I'm no expert at these matters,but I can tell you from my experience because I bricked mine P990 two times and was able to bring it back to life.
In both instances I used Smartflash, found V30a ICS ROM for it and flashed it over it, and it came back to life.
But when you do this,you will have ICS bootloader and you won't be able to install PA or CM since they work on the old bootloader.
Or you can flash it to the stock Gingerbread ROM https://hotfile.com/dl/168874678/8ea13eb/NVFlash_LGP990_V20Q_EuroOpen.7z.html
And I would recommend reinstalling nv flash drivers before,just in case the error is on your computer. http://www.mediafire.com/?cdgwwgkdozht8pw
Also, try All in one kit, http://forum.xda-developers.com/showthread.php?t=2020737 maybe it will help you. I repaired my bricked phone with it a lot of times. Its very easy to use as everything is explained there.
Jasper_bin
this device is 99% unbrickable
just go ahead with the AIOT by SPYROSK (this guy is a silent killer with amazing skills)....link in my signature
it works like a magic....real magic if you read the opening post and do it properly
Thanks
Hi Obersoldat,
I'm currently on the new BL - PA has a spin for the old, and one for the new BL. Is smartflash a windows-binary? Since I currently have no access to a windows-machine :-/.
Hi Make1 and Sreeprajay,
thanks for your recommendation. I'll also hit that thanks button if it helps me solve this, but first I've got two questions:
1st: As said above, I currently have no access to a windows-machine. Therefore I wanted to try working this out with nvflash on Linux. AFAIK this should be possible, even though there would be no nice menu-system. The question is if there's a difference due to the special drivers on windows which are mentioned everywhere? I ask that, because I've successfully rooted my buddies TP-Tablet on Linux with adb, and without any special drivers (which were said to be mandatory on windows).
2nd: What am I aiming for in Spyrosks AIOT? Instantly I'd think option 2B (Change Recovery with NVFlash) might help me. As in ProgMaqs Full-Brick-Repair. Then I'd look into the batch-Scripts, and simply manually execute the needed Steps.
Ok, so I dug up my old windows-tower from the attic, soldered a power-cord that I was missing, and fired it up. Took me more than 2 hours - thats what I meant with "no access to a windows-machine".
I ran Spyrosks AIOT, but no luck . The only possible ways to save this phone, are IMHO the nvflash based methods. But nvflash on windows reports the same error: "USB device not found".
Yes - I installed the driver out of the AOIT - but it seems that it cannot be activated for my phone. I think it's not in the right state to be recognized as a device that would need that driver, so windows won't activate it.
Attached is a screenshot of how the phone appears in my Device-Manager when connected in "S/W Upgrade"-mode.
Do you still think this phone can be saved somehow? I had high hopes as I read that this phone is nearly unbrickable
Come on, please someone help me. I'm not trying to be lazy here, or have someone else do the searching/thinking for me. I just can't figure out how to solve this - propably due to a lack of experience.
I don't think this is a simple problem - but there must be a reason why that phone is said to be 99% unbrickable. I hope I'm not the other 1% in this case.
Anyone?
I would have known what to do if the pc recognized your phone when you've installed drivers because almost exact problem happened to me few days ago.
Okay, now I will suggest random things well, I'm just trying to help :/
I suppose cwm isn't working?
Then about S/W Upgrade mode, have you installed APX drivers? Because when you connect phone in S/W upgrade mode with APX drivers installed then Device manager shows no errors.
You also mentioned that you restored a backup so it means you have latest backup of your system which you wanted to use. Tell me if I'm not correct. Then full wipe of your phone will fix everything, you will just flash a new rom, do the rooting stuff again and then you can restore your backup again.
maybe its because you are on linus, try restoring a STOCK GB KDZ if you are on the old layout, if you are in the new layout use a official LG smartflash, try that on windows and use AIO Toolkit !
Hey, thanks a lot! Actually the last Tip did the Trick!
After I downloaded and installed the full LG phone suite, I was able to restore the phone with the official LG support-tool. During the installation of the PC-Suite one or two new drivers were installed, which then lead to the phone beeing correctly recognized by the Windows 7 on the PC.
So to sum that up, and clarify the questions I brought up earlier:
Can the windows Drivers do more than what the native ones on Linux?
Absolutely yes! Only the drivers which came with the PC-Suite made my PC recognize the P990, which it didn't do before. Propably even the special drivers which come with Spyrosks AIOT depend on them (correct me if thats not true).
Can I restore my bricked phone with only Spyrosks AIOT?
In my case that did not work. Even after installing the PC-Suite and its drivers (including the support-tool drivers) the nvflash based methods in spyrosks AIOT did not find my device, which was connected over USB. But LGs support-tool did, and revived the device .
Hope that helps other people in my situation. The legendary unbrickability of this thing is proven once again
Thanks to all of you (Yesyesyes - I'll hit that button right away!)
