So heres the thing.
I flashed some firmware on my phone (did it 100 times no problem) but i got fail in odin.
I said ok nothing is wrong i can fix it. but to my suprise Odin wont recognise my phone. I get a message that the Usb is unknown.
Now beacuse i reinstalled my drivers i think that the computer needs a first time plug of another galaxy s to install the driver from the phone is that correct? (Cause my phone can only go to download mode)
so all i need to do is to get another galaxy s plug it in and let the computer recognise it for the first time. and than use my broken phone phone and it will work?
what firmware was it ,if it was ics sometimes you lose usb connections and odin wont recoqnise the phone

@Topic started i have the same problem and have a similar thread.

I used this one
Problem solved here. I hope this solution helps you
I've tried so much, seriously SO MUCH. At the end it turns out it was my usb cable. i ripped my old usb cable apart for making me go ape ****.
lesson? No matter how many times you install, change ports, etc. Always be sure to try a new usb cabel. If you don't have a second one, i'd suggest you go buy a second one, it's worth a try. The whole time it wasn't working it was my stupid usb cable, changed it and in an instance i was ready to roll.
Wish you good luck!
Hi, to all.
I'm not sure i am the only one who has this problem on i9000,(i suppose not),
in any case i haven't found any thread related for our phone.So i thought it would be a good idea to start one,and if others have same problem, post here, so we can gather as much info we can.And maybe find a solution.
ANY HELP IS VERY APPRECIATED.
From what I've read on forum it's defined as: ''when a phone perfectly works but it is unable to make its usb micro port work in any way''.(Except charging).To precise, i mean make phone visible in download mode or able to enter in download mode,usb drivers install, transferring files to/from computer to internal memory and sdcard.
The only threads i found are for HTC devices,with no clear solution.
User Bejda gently gave me a link on a French forum with a similar problem.
It has alot of interesting info and personal opinions about the problem.
http://galaxys-team.fr/viewtopic.php?f=6&t=20841
Another link is this one referring to a program that can unbrick and make functional the usb port.
http://galaxys-team.fr/viewtopic.php?f=6&t=22257
POSSIBLE SOLUTIONS:
1)GOOGLE DRIVERS (As i use cm7) --Didnt work in my case
2)Other cm7 version or other kernel from CWM --Didnt work in my case
3)Other pc usb port --Didnt work in my case
4)Other pc or format --Didnt work in my case
5)Other usb cable --Didnt work in my case
6)Mobile Odin --Cant use that to put stock firmware as i need to repartition and pit, and these options are disabled.Can they be enabled??
7)Clean Usb port/Check if it is ok --Didnt work in my case
8)Use Jig -- Didn't work either.
9)Use the program from the above forum??
10)Heimdall --Finds uknown device with 0000 ids etc,and fails to install device.Does work.Tried latest version.
11)Tried toggling BT--Didnt work.
12)Having the phone connected to notebook and then turning the notebook on -- Didnt work in my case
12)APPLYING CM9 ICS! -- YES THIS SOLVED MY PROBLEM!!USB DISCS WORKING SO AS ODIN ON DL MODE!!!!!THANK GOD!
Can't think something more..
About my case:
The phone works perfect but i cant manage my pc to 'see' my phone.Charging works.
The 2 discs of the phone
or even odin cant be seen.I tried different pc's,usb ports,usb drivers/controllers,cables,download or not mode,usb debbugging on/off , samsung and google drivers.
Other cm7 versions or kernel versions.Formatting the pc also.Whereas my friends phone on pc works perfectly,mine 8 out of 10 times is not recognised ,or found as uknown device.
Discs (internal and sd) also not shown on my computer.
On 3-4 days of trying i only managed to get it shown for 1 minute(only discs) ,didnt have time to try odin,as it disconnected (without me touching anything).After that it did the same before(not recognized etc).
I also dissembled my phone and i can say usb port seems perfect.
I was thinking if i manage to make odin work i can repartion and (update bootloader????) also put stock firmware/kernel that may fix it ,or not???
Or at least with stock i can try samsung's warranty.
Anyway for now i use My phone Explorer (via wifi) that can access eveything (contacts,sms,calendar,both disks on root folders etc,and its free)
because ftp apks dont work for me.
I ran into the same problem a few weeks ago, tested it all that you write about, but eventually I gave up and sent it to Samsung, they changed the circuit board on the warranty and now it's on its way back from service.
I said I tried to update the phone in Kies and that something went wrong ....
If you have a custom ROM on your phone, see if you can "destroy the software" so that they can not get into the phone and find that you have broken the warranty.
Thanks for your answer.
Well,you were on custom firmware/kernel?
I don't know if this can be done as i am on cm7 and i use a non stock kernel.
if you are on a custom rom you could try odin for mobile to flash a stock rom and send it to samsung (if you are still under waranty) for repairs/checks

Hi,thanks for the answer.
As i said odin cant be used because phone is not recognised by the pc in any way
For me toggling bluetooth helpt ...
I had same issues, repaired by replacing micro usb port.

Even when i enter in download mode with Jig,i cant make Odin see it in anyway/or install drivers.
Tried also BT toggling as stated,but nothing.

I did sent to rma, but I have done for my friend, because he was out of warranty, not so difficult if you have proper soldering tools. Well its not cheap to get them, Im working with pc's motherboards, and soldering components is my job.

i hope you understood that i was referring to this
i had this problem so many times even with my ex-galaxy spica.
My solution is very weird/unimaginable : One day, my spica remained plugged in my pc portable turned off. When i booted my pc portable,in my bios screen, my phone said it was connected in USB. It was the better day of my life
Precision : my pc portable is very old ( compaq presario R3200 )
From that momment, every USBrick was just matter of time

sorry i read too fast.Problem remains also even with Mobile Odin.
I am on modified kernel and cm7.
If i try to use mobile odin to put stock firmware kernel i will soft brick my phone as i need to repartition and pit,and these options on mobile odin are disabled

Repair to a shop or samsung?
Claimed warranty or not?
i've got this problem to, you've probably got a faulty usb port, look into the port and see if you can find all the copper connectors, just today i tried a brand new usb cable, an that works!!!
only... it works 1 time, the first time the copper connectors aren't pushed into the cable, just look at an used cable and see what i mean, the connectors in the middle are pushed in....
what i think is that if you use a set of tweezers to pull them 1-2 mm out, (so they are lined up with the outer connectors) you can make contact again, make sure you're already in debugging mode, if you have used the cable you have to do it again..
btw, i havent tried the tweezers, i had a noever used cable laying around, but it's probably the same idea, so the same effect.... please reply if it worked or not...
btw^2 you're getting the "unknown usb device" error are you not?
Sorry for being late.These days i was ill
Yes maybe i have a faulty port.
But i can't claim warranty because i have glitch kernel and cm7 kang .
I just want to try 1st everything else possible , before a repair.
Also i don't like alot the fact that i will stay without my phone.
I will also try these days to keep it plugged on my turned off notebook (as oxmoss said)
and also try cm9 with cm9 kernel (as Dopedangel said).
Only sometimes (like 1 out of 10) it gives me unknown usb or usb malfunctioned,and (like 2 out of 1000!) it found the phone correctly.
These days , some times if i try to 'move' the cable near the phone it finds the uknown device
but i cant do nothing more. And sometimes i also hear the sound of the speakers getting 'stacked' when connect the usb..
So it must be the usb...
But the pins seem perfect.Also the ones inside the motherboard...
I tried with tweezers but nothing,as everything seems ok...
Anyway for now i use My phone Explorer (via wifi) that can access eveything (contacts,sms,calendar,both disks on root folders etc,and its free)
because ftp apks dont work for me.
Anyway i will try the above solutions and update these days the thread.
Thanks again
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
Sent from my LG-P990
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!!:

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.
Hi, firts of all sorry for my english.
My sister give to me a BLU R1 HD 2GB RAM/16 ROM, it come without Amazon ads (so i think its OEM version). Its running BLU_R001UU_V21_GENERIC.
She told me that one day just not was recognized by PC to transfer files,photos, music. I make a wipe from recovery and still the problem no USB detection at all just charging, no sounds like new USB device was conected, no device on Device Manager.( i do this on diferents PC Windows 10, Windows 8, and Linux Elementary OS , Deeping OS)
I enable Developer Options and change MTP/PTP/Only Charge option and nothing happened; I opened the device to check the pins on the USB connector and check continuity and all seem like be perfect.
I thing that may be when was update to the last software something happen and lost USB recoginition, I want to Root the device and change Recovery but i see that the steps need connect the R1 HD to PC and make some things throw ADB console.
My question is: can i downgrade the original rom from SDcard in the actual Recovery.. to try recover the USB functions. or may be its something wrong on any internal chip that no make the USB conection.
Ty.

I enable Developer Options and change MTP/PTP/Only Charge option and nothing happened; I opened the device to check the pins on the USB connector and check continuity and all seem like be perfect.
I thing that may be when was update to the last software something happen and lost USB recoginition, I want to Root the device and change Recovery but i see that the steps need connect the R1 HD to PC and make some things throw ADB console.
My question is: can i downgrade the original rom from SDcard in the actual Recovery.. to try recover the USB functions. or may be its something wrong on any internal chip that no make the USB conection.

I have not seen any other reports of usb dying after OtA update. You say you tried with different PC, what about using different usb cable?
But more bad news for your plans. If you have official v21 update, then you are not rootable anyway.

I have the exact same issue... and it happened just after an OTA Update. After that it showed it was charging only when the phone was shut down.
No USB recognition whatsoever. PC/Mac. Tried several cables.... All USB modes... Factory Reset... Nothing made it work.
I contacted BLU with the issue. As soon as I have an answer (If ever) I will let you know.
If any of you know anything about this please share it here.
Oddly enough, After a cache wipe and factory reset, I have no ads on the lock screen. The app is running on the background but nothing shows up.

I think if we can downgrade to a official rom under the actual recovery maybe that fix the USB. But all methods are under USB connection to PC.

As far as I know downgrading is not possible without making the phone unusable. If by any chance that is possible maybe an update from an SD Card can work.
