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
Sent from my LG-P990
Even if the coputer act like there is nothing plugged ? On several computer I used the phone wasen't recognized as a plugged peripheral (even a usb key).
I had the same problem, v3.5 of lg united driver was cqusing it , when I updated it got fixed just uninstall reboot and install 3.6 worked for a few more peps

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 folks, I know some of you are going to jump straight down my throat, but please, back off and stick to the friendly forums that this used to be where anyone would help anyone.
the story so far is that I once loved my Nexus One, I've had it since launch, I have ran Cynogen Mod 7 for a couple of years, I have had MUI roms running, I have played with various kernels, updated radio, upgraded hardware, all was going wonderfully.
the one thing I could never get was full SU!! Heck knows why!!
I then started getting random problems and downloaded the original google frf83 software and flashed the phone via update.zip using amon-ra recovery.
I thought all was well after this, as my phone received 3 OTA updates and now my phone is on...
Android 2.3.6
Baseband 32.41.00.32U_5.08.00.04
Kernel 2.6.35.7-59465-g42bad32 ([email protected] #1)
Build GRK394
I noticed that in the Status (settings) it was displaying my old sim card number, which is not the number for the sim in the phone now. his I thought was odd and that something had gone wrong.
So as most of us would do, I went to boot AmonRa recovery and it wasnt available, it had been overwritten with the default recovery; ok lets just ADB and reflash it, I hadnt used ADB for a couple of years because I did everything through AmonRa's awesome recovery!!
So off I go, install the SDK, all the appropriate packs including the USB driver, just like I did when I originally flashed the phone with the recovery image!
But an old problem came back that I hadnt even been bothered about because I always put stuff on SDcard via a card reader!!
I have had consistent problems with my nexus one for some time now in regards to the USB drivers, no matter what I do the phone will not install and I believe it could be some conflict in the device.
I am running Vista Ultimate (fully registered) and no matter what I do I cannot get the Nexus One to install. It will only display as unknown device, which is absolutely useless.
I have browsed every post and tried everything I have found, and yet nothing is working. I have used devmgmt, I have tried the roll backs, I have tried to install every driver available to get it working. I have uninstalled the device, updated drivers after fresh install attempts, I have even formatted my laptop thinking it may have had a corrupt OS and bought Vista Ultimate.
I am not a complete noob and I have been around these forums for some years, but I never thought I would have to cry out like a 4ucking Noob with such a seemingly simple problem, but it is not simple, I have done everything I can possibly find!!
I must get the USB working in order to get the recovery back, I can access my phones default recovery but it will not work when trying various roms as update.zip!!
I have tried the terminal commands on the phone to install the recovery.img but I do not have SU access and the phone point blank refuses.
I have attempted to change and remove the recovery files reffered that are causing the revert to default recovery, but shock.. I cannot delete because of insufficient permissions. I cannot ADB because the USB driver refuses to install.
So if I cannot change the files due to permissions, I cannot ADB because of USB, I cannot get to Ra's recovery because of bootfiles, I cannot use default recovery to update.zip... I am absolutely losing my mind and I'm going nuts browsing the forums for the second week running, yes I am now on day 12 of trying to fix this problem and at a complete loss...
Can someone please help??
I will even allow remote access to pc because I am that desperate to resurrect my beloved Nexus One.
I also have a Galaxy I9000 without 3 button download mode but that is an entirely different story!!
Please just someone, come to an oldskoolers rescue, and yes PAYMENT will be given to the knight in shiny armour!!
You could try on another computer which doesn't run Vista

Or just use fastboot instead of adb...
His Nexus One isn't recognized by the computer, so that won't help unfortunately. Also, I've never heard of build GRK394..

Install the drivers for fastboot already Jeez and then read How to use android for dummies.
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.
So about two nights ago I noticed my phone wasn't taking a charge and eventually died. Once the phone was powered off it charges fine but turn it on and no more charging or connect to PC. So I've been searching for a solution since then as this would seem to be a software issue but nothing I have done has made a bit of difference. Now I want to bring the device back to 100% stock to either start fresh or make an exchange with T-Mobile.
Every way to restore to stock required fastboot & adb which obviously I cannot do since I cannot connect to PC. Please share any insights or at the very least steer me in the direction of the light. Thanks

First, if you can boot into android, download a zip of your stock from your phone and flash it through recovery. If you can't do that, see if you have another micro usb cable, try connecting it to your phone and pc and see if that works. If not, cycle through your boot modes connected to pc (bootlader, android -if possible-, and recovery). Do you hear any sounds from your pc that indicate something is connected to it? Especially important for recovery to stock. If you hear a sound when you boot into recovery, you can flash the stock RUU or zip to get your phone back to stock. Next, disconnect phone from your pc, uninstall htc sync and all drivers for the phone. Reconnect the phone to your pc after that, and if it boots to android, it should reinstall sync and drivers automatically. Aside from this, the only other thing I can think of would be an exchange due to faulty usb. Hope this helps. I've included a couple of links to your stock RUU and zip (I'm assuming your T-mobile US). I hope this helps. -Mike
T-Mobile stock nandroid zip (Note: You need CWM for this)
T-Mobile stock RUU (It's an .exe you run with the phone connected to pc in recovery. Scroll to the bottom for the download. You need stock recovery for this)
I hope this helps.

One more thing: You got lucky no one flamed you for posting a question in the general thread. Next time you should post a question in the Q&A thread. Not everyone is as nice as me around here.
hi. i'm having the same issue on att variant... reported in depth here:
http://forum.xda-developers.com/showthread.php?t=2408656&nocache=1
Basically, I have posted this exact same problem here months ago, but with not a lot of help. I came here to get help and I intend of leaving with a bit of some. Basically, I rooted my HTC One, turned S-On, and finally installed Cyanogen Mod. Everything was working for the most part. I remember being able to attach my phone to my PC and being able to transfer files over to my phone. Recently that has been working out so well. I try to transfer files from my PC to my phone, such as music/videos/etc, but my phone doesn't show up. I can go to device manager and see my HTC One under other devices with the caution triangle, so basically my device is read to be connected to my PC but is lacking the drivers to use it. Like I said before, I have posted this problem on other forums before, and I have been sent the link to the drivers. I've installed HTC drivers, USB drivers, HTC One Sync, and so much more, but none of that has worked. All that happens is that my phone will connect to my PC, charge, be noticed by the PC but is completely unusable from PC to phone. On the phones side, it's 100% okay. No problems other than the simple nightly bugs, but I know it's the ROM version I am using. I reverted to the last known stable Cyanogen Mod, and the one previous to that. That hasn't fixed the problem as well. I'm running out of idea's and I'm just looking for some help. If you can help, rather then posting a link for drivers and thinking I'm retarded, please do so. I will appreciate it to the fullest. As for that, that is all I have to say. Please help, and all help is appreciated.

Ok,
I think the best thing we can to in this case is the classic troubleshooting.
Try different USB Cables, slots on your PC, DON'T connect it to a USB HUB (I think you already know that.. I just mentioned it to ensure that)
Make a backup and flash the stock Sense ROM
If you can get a connection to your PC .. Cyanogen causes this issue
That was to determine wheter it's your phone or your computer that causes this issue. Pretty basic.
Uninstall your drivers from the device manager interface
Uninstall everything that is related to your HTC One(HTCSync, maybe Kies or other programs like this, Every driver)
Now, make a registry clean to reinstall everything on a clean way
Use Wise Registry Cleaner
Proceed a computer reboot
Now, download the latest version of HTC Sync
Install it with every driver component.
Then uninstall HTC Sync WITHOUT the drivers
Plug in your phone and wait until other drivers are installed
If that's done, try if the connection works
