Hello
I had some trouble with a bricked SGS for about 3 weeks ago but got it on the run again with some flashing help.
Now i have this strange problem. If i turn it off or if it just goes black out, which it has begun to do after i flashed it, then it can't turn on, it just show the sun looking loading icon and then a empty battery icon and then turns off.
I can't load recovery mode with the combo, but i can make the download mode combo work.
But if i connect the phone with the charger/usb i recognize it and show that it charging up. Now it boot and shows the Galaxy I9000 model no. image.
Had tried flashing newer versions From XXJPO -> XXJPY -> XWJS3 and both with and without pre-partition and it still occur.
Now the question: Does any of you experienced people know this problem and can it be fixed somehow ?
Thank you in advance
First i would liik to charge phone for 24 hours and also check with another battery .

The battery don't seem to be defected. Once the phone is booted with a cable connected, it goes without problems. It just will not boot without a charging signal.
Bump - Still actual
Try using Block 2 Odin method here to go back first to Eclair and if that works test phone then upgrade to Froyo .

That happened to me a while back and I couldn't find a fix for it. Ended up doing the above and it resolved it.

i agree wiv the suggetions frnds given.galaxy is hard to brick.i did all sort of unusual things an even uptodate lol.don worri m8 jus flash to older stock and hard reset.check the connectivity pins,to b clean even the battri pins.somtimes its best u format ur eternal xd on pc an format.and giving another hard rest makes things better.i had once formated my int sd on pc and the phone had emptied,then i flashed and things worked fine.personally sticking to stock rom is better if u dont wan troubles,cause every custom rom has som drawback an needs a lil knownledge to tweak it up.check kies if ur on it,i recomend download the recovery driver in it.hope u get some help.cheeeerzzzz
Same here...
Hello everyone,
I too have the same issue as stated in the first post.
I even had issue sometimes that when boot up.
The USB notification icon wouldnt turn off even if i wasn't connected.
Some threads suggested that I clean the USB port, which i did and nothing changed, even if it looked a little bit dirty in there (Hard to say since it is really small).
Now the USB port looks just as new but same issue: I cant power on the unit witout having it connected with a power cord.
Also, when offline in download mode, Odin detect the unit and I can flash my device (Which I did yesterday by flashing UGJH2 re-partition and UGJL2 not re-partition) but when boot up, I can't make it to sync up with the computer. No sync possible (Also now I'm not rooted anymore).
The unit is under warranty but since it is unlocked with a tool that needed rooting to lock back, abviously I would need to be rooted again but to do it, I need to be able to sync it with my PC (No cant do here).
I have some engineer at work that offered me to check it out for me, they think it is related with the USB port, but I'm worried about the warranty seal. I found how to disasemble it but does anybody knows where it could be located on the I9000M from bell (Vibrant)? Does it have one?
Anybody have any better suggestion or a second opinion, please?
Its my 3rd Galaxy S from Bell and Samsung is now the last company I would think when buying a new mobile.
EDIT: Did the Block 2 Method and now it doesnt even want to boot at all (Did the JPY_JPY_JPY.tar part), now it shows the loading sign even faster and the battery doesnt even show it self at all.
Hello again people!
Got my friend engineers to open the phone and they didnt find anything that would cause my issue (Also no warranty label...).
Does anybody knows how to root a Galaxy S with Froyo without a PC?
I want to return my phone to Bell Canada under warranty but my phone is unlocked and I want to lock it back before sending it back and I need to be rooted to do so...
Thanks for your help!
I got the same problem here. Could someone tell me more on this. What is this Block 2 ODIN method?
this problem can be caused by water or sweat that got inside the case of your sgs.
the biggest hole in the case is micro-usb port) i think condensation accumulated there and locked some contacts.
try to disassemble the phone and carefully clean and dry it.
this helped me.
Hey folks. I'm hoping to get through this in one piece, with one walkthrough.
I recently messed up in flashing a Rom to my Captivate. It cleared the phone of firmware and left me with the AT&T splash screen.
I bought a jig, and am now at the "Downloading..." screen and am trying to take this slowly to ensure a properly functioning phone (I've been without for two weeks now).
I've read through the sticky post [link]http://forum.xda-developers.com/showthread.php?t=884364[/link] and have most of the downloads. The Odin link is dead, and I don't have the proper version (I used a version I later found out was bad).
What I'm hoping for is to get someone to show me where the proper version of Odin is, and maybe give me a quick guide to doing this for a Rogers Galaxy S Captivate.
I hope I'm not coming off as lazy, but I tried this solo, and it went awry. Thanks for any help in advance.
This is the link for Odin. http://forum.xda-developers.com/showthread.php?t=731989
You want to Open Odin, then use the jig to put the phone in download mode, connect usb to your computer and wait until odin recognizes your phone. Click Start and sit back and wait. You should then be able to put whatever rom you want on the sd card and flash
Okay. I got the proper download, and used Odin. It reported success.
I haven't unplugged the phone from the computer yet, but it's also not showing as a drive on my computer. I'm at the stage where I'm supposed to root the phone after using Odin and before flashing.
Should I unplug the phone, or is that going to send me back to square one?

If you used that Odin 1 click you will have the AT&T version, it will work but you will have the AT&T boot up screen. After it is finished your phone should reboot by itself. If it didn't try pulling the battery and then turn it back on.
Driver Installation Issue at Fault?
Okay, so I'm starting to wonder what's going on with the communication between my phone and my computer. I have the drivers, but when I try to install them (64 bit, for a dual-core, right?), it claims to fail.
I think maybe that this is the reason I can't get the computer to recognize the drive. Also, when plugged in last time, it said it failed to install drivers again. Even when the phone was operational, I had issues with that.
So . . . I'm wondering if maybe I solve that and the issue becomes seamless. Any thoughts on this would be appreciated, as it seems I'm stuck until I get the phone to register. Even Odin won't see it now, although I've already passed that step. F-Bomb.
Did you get the drivers right from samsung web site if not thats why they wont install i had same thing when i got my cappy.
I got drivers from.samsung.com installed em worked perfect sence. i kept the download saved had to install em a few times over the last 9 or so months. Only because of all the dam software hardware i run. Good luck

Just because it's a dual core processor in the computer doesn't mean you have a 64 bit OS.
You might want to know what version of windows you have...just a thought.
Okay . . . I can't seem to resolve this driver problem, nor can I move forward in the previous issue of getting my phone back to a functional state.
I can't imagine what I'm doing wrong that everyone else managed to avoid. Could I maybe request some one-on-one time with an experienced Rogers user? Just to recall the exact steps they took in order to successfully UNSCREW their phone.
Again, I appreciate all the help. Every post is making progress. I'm just frustrated at my ineptness with solid state installations.
I'm still not able to install the drivers or get my computer to register the phone as a drive. I did a bit more reading, but I've found nothing but different driver links. Has anyone else had this installation failure?
I have had driver problems before...try plugging up phone; on computer control panel, device managment , go to were it has device (just click then till se something about samsung) then uninstall drivers, next unplug phone, reinstall drivers that are on design gears (developer) thread for odin one click, next plug up phone sbf it will say new hardware and install drivers then see if that works... Ps if need to just pm me and I will get back to you to try and help

Try it again, however this time plug your USB cable into the USB port in the back of the computer.
Drivers were installed properly with Toolbox. Thanks for the help
ok first off I have searched and have yet to find a sollution. So if there is one please flame me and point me to it.
Problem : I have 2 computers, both win 7 x64 pro. my desktop does not detect any cell phone, my friends droid 1 or my samsung captivate..... Both have all the drivers installed. That is a small problem because i have a laptop that does ( DID)
Big problem : phone having problems, me flash captivate and flash fail ( i think i used odin 2.2 flasher which for some reason doesnt want to work, i tryed it a few times before... but anyways so I'm in download mode and now the computer wont detect my phone, just like my desktop, I get the UNKNOWN USB device or the usb device did not install correctly blah blah blah malfunction... SO now I'm able to get into DL mode but thats it.... so where is the fix for this? Please help . its so strange that no changes were made and it goes from having worked for months to not working at all suddenly...
Again neither odin v 2.1 or v 2.2 ( as in froyo and eclar) will detect phone nor will the hemdol program or what evs.... so i can not boot past download mode. Please help .
the answers are out there... itll just take a bit of reading... however sounds like there are program incompatibilities somewhere not allowing your drivers to install especially after you said drivers did not install blah blah. Also try changing usb ports when you plug it in and go through and check to make sure all you usb drivers and ports are functioning properly. Furthermore check to ensure your charging port isnt loose and or pins bent or broken same with your cable.
try this as well... says right click and run odin in admin etc.

What rom are you on? CM7 MIUI?
Well huge problem... for some reason the phone wont charge now so now i cant even get in DL mode and before that i couldnt for the life of me no matter what i read find a fix for the USB issue. idk what the **** it is but its really annoying.... I was using OFFICAL 2.2 and was trying to reflash it and try it again or flash 2.1 because i was getting random restarts. then the flash failed for some reason first time ever I think ( i seriously have flashed about a dozen times since ive had my phone over 9 months, So i know alot and have read alot, have a jig and all that jazz) so i know what im doing... I just got my phone back from samsung about a month ago they fixed a random button pressing problem, and now the turning off on a Stock rom ( plus firefly prior, why i went back to stock) made me paranoid, plus i use it as a clock for work so i cant have it turn off randomly at all. So what am I to do? I possibly can use my friends battery for a bit or my womans... but im thinking maybe this has less to do with computer now and possibly that my phone fried or something that i should send it in to samsung for warranty repair...since obviously if it was restarting on a new 2.2 instalation obviously there were probably some problems...
I read a similar story of this randomly happening to another experienced user on google, and he sent it in to samsung and they just sent him a new phone... my AT&T warrianty is long gone on my refurb but i still got 3 months left with samsung... idk why it isnt even charging on wall outlet or computer...
what to do?
Did the phone go "dead" after a failed firmware flash? Or it literally just all of a sudden won't charge? If it was truly random then it's a hardware problem all the way and most likely an issue with the USB port or a trace routed through it. Only 2 lines control charging and the Captivate is notorious for a pretty solid port from my findings.
Well I left my phone in the wall for hours and I guess it does charge so its not completely dead. Now just the issue of reflashing stock on there... so getting the USB to work in my computer. I take it the USB in the phone isnt dead or the JIG wouldnt work... I just want to know if the Random shut off is hardware related or a bad flash / rom? Anyone know what has less problems? 2.1 or 2.2? I dont think my keyboard is in 2.1 so i dont think i could take it... but i just want a working phone with my gingerbread keyboard <3 I just dont want it to turn off on me...
and now randomly odin's will still not detect, but heimdol will, but it fails about 18% into factoryrfs or what evs. And Yes I have used it before and yes I am following all directions. WTF this is blowing my mind... and yes repartition is selected
Are you using an OEM Samsung Cable? Don't use knock off cable for anything more than charging...
just fyi if u rooted ur phone and samsung checks the programing to find out and trouble shoot it will void your warranty and youll have to pay for it... so um maybe try spending the 50 and go with a refurb thru insurance.
Yes I'm using stock cable...
ANd its not rooted, its not ANYTHING since there is no OS on the phone so no way to see anything to void anything...
now most things ( on different computers) will detect the phone and all odin and heimdol but they will both fail at the beginning of any flash... Its like nothing can be pushed through the phone.... ?

It doesn't necessarily screw with it. Heimdall installs a custom WinLIB USB driver to operate with Samsung Composite USB devices. This driver is used for Samsung Download mode which ODIN doesn't recognize. To switch back to using ODIN, you just need to go into device manager and uninstall the device and be sure to DELETE DRIVER FOR THE DEVICE. Then just plug the phone back in when in DL mode and the Samsung driver will be re-installed. However, this is really beginning to sound more like a hardware problem. I emailed you back and would be happy to put a final diagnosis or repair on the devil 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 should be getting it within the next two week, hopefully that doesn't give me the same problem

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:

This is my last froyo teclel stock backup

Disclaimer: Even though I'm sure it will work, try it at you own risk, I'm not responsable for any bad behavior or damage that could happen to your phone
UPDATE:
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.

Lucky you! I was to in DM 1.7 but when i was in hidden menu i chosing another port, don´t want to save the settings. Anyway congrats!
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
