I am trying to connect via USB to my PC, not having much luck. I've tried several micro USB cables, and tried plugging them into every USB port on my PC.
When I plug in, and view "Devices and Printers" in Windows 7 32-bit, I can see a total of 6 LG devices show up:
LG Android Phone
LGE p999DW USB Device
LG Android (modem)
LG Android (NMEA)
LG Android (Serial)
Android Sooner Single ADB Interface
But literally every second some of them fall off the list and some reappear, sometimes they are all present for 1 second, sometimes none of them are present, and every combination in between.
I have no ideas left here. Uninstalled the LG driver from control panel, and reinstalled. Tried brushing out the USB port on the phone, as well as the old NES 8-bit blow method, no luck. Lots of cables tried all of which have worked in the past, no luck. Anyone have any thoughts?
Put the phone in apx mode by taking out the battery, holding vol +/-, plugging in the phone and waiting until the driver is ready.
Apx mode won't reconnect if dropped. .. I would guess a bad USB connector if the problem exists.
Also if the PC is overclocked turn that off. It messes with USB.

sound like a connection problem, either with the cable or your physical port on the computer
So it's connecting fine in APX mode, it stays connected in Devices & Printers. But I can't run the LG Mobile Support Tool from there, I've got to boot into Android. As soon as I boot into Android and connect USB, it's dropping the various device profiles in and out of Devices & Printers ever second.
Does it seems odd that I get a good solid connection in APX mode, but not when connecting with Android booted? Seems if the problem was with the USB connector on the phone, it would be an issue all the time.
Any other suggestions? I've tried going back to stock recovery and stock ROM, same issue. I'm really just trying to get the baseband update.

So you can safely say that the connector is good and cable its good. This suggests a software problem... either in Android or PC.
You can try the cleanup batch tool but I doubt it would solve the issue. Does not hurt to try though.

Are all of your Lg Drivers up to date?
No luck there either. Seems like a hardware problem, but it works fine in APX, only cutting in and out once Android boots.
I've been having the exact same issue.

Great, we've got strength in numbers!
So I've tried everything. I've flashed to stock recovery and OS, uninstalled the LG driver and reinstalled, multiple USB cables, different machines, USB debugging on/off, and every combination of things I can think of.
Sucks if if it's a hardware issue. Out of warranty period and I don't want to pay $130 or whatever the insurance deductible is for something so small... but I can't get 2.3.4 loaded without getting USB connected.
I'd be sure it's a USB connection problem, if I didn't get a smooth steady connection in APX mode. I've used NVFlash several times without issue.
Yeah I've only noticed it since i got the 2.3.4 update.
I've tried all my usb ports, and it will pop-up.
Last night i finally got it to let me decide to turn usb mass storage on but when I opened my computer nothing was showing up.
Just got a replacement g2x today after a long battle with my old one's usb port. When i was troubleshooting, I found that vmware and blackberry drivers can cause conflicts.
Try plugging in the phone and removing the drivers for all the LG devices you see in device manager.
btw... brand new replacement phone, if i move it the slightest bit while connected windows will play the disconnect/reconnect sound. I think LH just screwed up in the port design...
There's a funky greenish sticker around the usb port on this new one. Not sure what thats all about... cant tell if this is a refurb either.
Finally got mine to stop. I did a system restore on my laptop and it was good
@captmorganz the green sticker was on both my originals, and to check for the refurbished or not there is a code on the back under the battery by the screws that shows p999dw for original and something close but another letter at the end for refurbished, can't think right now since I've been at work for about 15 hours doing nothing and drinking coffee for the past 5 haha, excuse the rant.

Hello, I have a Samsung focus that use to work fibe connecting to PC but off recent whenever I plug it in windows 7 says USB is not recognize.
I've tried everything from resetting the phone to refatting the computer nothing helps. I have a feeling its the phone because same problem on other computers, anyone had to problem and cured it?

or it might be a problem with your usb cable that came with the phone. if u can, try getting another one and using that (they go for very cheap on ebay). Have u *unlocked your device lately?
I've tried many different USB cables none works for me. I got the phone almost 2months now already unlocked. Live in UK and its a ATT branded phone so I'm abit screwed.

Have you tried the microsoft answers forum (answers.microsoft.com)? They have some solution wizards in one of the stickies near the top.
Did anyone ever find an answer to this? I've had my focus since Nov last year and it's worked fine for me aside from some odd, and random nonsense.
I went to go connect my phone to my laptop the other day and realized it didn't see my phone. When I plug it in, the phone chimes and shows it's getting power, but both my laptops show nothing being installed, Zune doesn't load, and if I load it, shows nothing connected. Nothing appears in the device manager either. I get no error message.
the cord shows no damage, and it's been plugged into my wall outlet for awhile. I guess i'm going to see about getting another cable tomorrow and try it that way?
Was wondering if anyone else has had a problem with the cable going bad suddenly, or if something else could be to blame? I've been reading here, MS's site and anywhere else I can, and I find things ranging from error message, drivers not installing and other things. I just know it worked fine a few weeks ago, but now...nothing.
Had the same issue. My 4th USB cable did the trick. I wanted to throw it out the window

I don't know much about electricity, but every device I can remember having with a removable charger: instructions said Plug power cord into Device FIRST, then Plug into Power Source. Could leaving cord plugged into power source, thus reversing above instruction, cause a problem with the cord?
Used Nvflash to root a while back ago. Worked flawlessly.
Started having problems where the TF was not connecting up to the PC (both laptop and desktop). No problems charging. I know there's something going on cause when I plug the TF into the USB port, the screen comes on. When I unplug it the screen comes on.
Thought it possibly was the the ROM (Prime 1.7). Wiped caches and re-installed. Nothing. Wiped data & caches and re-installed Prime 1.7 from scratch. Nothing. Wiped data & caches and installed Prime 1.6. Nothing.
Everything works fine other than I cannot get the TF connected (detected) on the PC and I cannot get into APX mode. I'm sure they're related. Did a search for not being able to get into APX mode and found a couple but no help.
I can get into recovery and see the tf in adb. Don't know what else I should be looking at.
[Update]
Just got the TF back from Asus. Missed it sooo much.
The ticket inside said they couldn't find any problems with it.
By the time the TF was off to Asus, I got my extra charger and cable. Tried the new usb cable and bam, device found. Most likely I was in APX mode but due to the cable, would have never known. The odd thing is the cable charges both the TF and the dock perfectly. All that for a f-n cable.
Now I'm fighting with Asus to replace my cable.
I hope this finds its way into others having the same issue.
Are you trying with a Linux machine or Windows?
Make sur you have all the required drivers installed for windows. APX requires additional ones....
On linux you will not see the device automatically when in APX but you can execute the nvflash script
Unfortunately I only have Windows machines.
When I press Volume Up + Power, I get nothing. It doesn't detect there's an APX device in my device manager for me to even install the drivers.
Also tired Volume Up + Volume Down + Power and nothing
Went back to total stock and I still can't get into APX mode and can't connect to the PC.
Talked to Asus support and they're stumped. Was told they had to research and get back to me.

This just happened to me. I booted HC then went to applications. Disabled/re-enabled USB debugging, then I went to device manager on windows and clicked "Scan for Hardware changes". It worked after that.
Tried that method as well.
Sent it off to Asus on a RMA. Crossing my fingers
Sent from my HTC Glacier using XDA Premium App
So this just randomly happens to me the day before I am supposed to sell it to someone. I went to nvflash it back to stock and noticed this issue. You said you restored it back to stock before you sent the RMA in, how did you go about doing so? I'd like to get it fixed so I can sell a functional unit.
Thanks
I'm also facing the same problem with my pc/laptop not detecting the TF101. The service center is of no help and they just give me the usual answers - try other pc, check the cable etc.
Moreover, I cannot go into recovery mode even with all the necessary drivers installed. Only a green droid with an exclamation mark.
I've no problem rooting the tf on older firmware. Wondering if the bootloader is locked.
I think it sounds like the usb cable as the op said it fixed his issue. I'm looking around for one to test on.

Im on prime 1.7 and just experienced difficulty connecting, but can still charge. I just started the troubleshooting and found this thread. Disappointed, yet happy that its probably only the cable.
Well do you get any response from your computer? Anything, like a sound? a error installing drivers? a unknown device? Are you using the docking keyboard? Also this may not be the case but make sure you dont have a USB hub or anything extra on it. You can also try connecting it to the computer and open device manager and click scan for hardware changes. See if something new comes up. I have a couple more extensive ways of testing but let me know if this helps.

I recently tried to flash to different rom and got stuck in the Asus screen. And now I can't do anything with the tablet. It only shows as unknown devices on my pc. Any thought what happened and how to fixed it? I'm really appreciate your help
Okay, to make it short, I've brought home a Samsung Infuse for testing. It's not even a day yet and it's showing one hell of a problem already. Firstly, I can't install the right drivers for it. I've used Kies and tried downloading every drivers I can find but no, the phone won't even connect as mass storage. I tried going into download mode by holding the volume keys and insert the usb cable but it only gets in download mode once every 20 tries or so, the other times it just boots right into the OS. In the rare cases of successful download mode, Odin won't recognize the phone. I used SGH-i997-UCKJ4-One-Click and finally it said the phone is connected, but intructed me to install the right drivers. So I did exactly as it said but the whole process of reinstalling drivers just repeats. I put the cm7 and mosaic ROMs in the phone using wifi and flashed them, here I met another problem, the phone keeps getting into car mode. I disabled it, and the phone changed orientation although I tried disabling it back and forth. I'm raging at it here, does anybody know about these problems or should I throw the infuse at the seller's face?

sounds like an issue with the usb port not the drivers.
try cleaning it, or you may need to send it to samsung for repair. if you dont want to do that then i'd make you an offer on it, but you might be insulted at what id pay for a "broken" device.
Something I ran in to as well, I ended up using the ports on the back of my PC.
Something else too ... I ended up using a Blackberry USB cable.
Hope this helps

Yea not an issue with infuse but the USB port. My laptop connects to it if I use the secondary or tertiary USB ports.

people read the whole post. his issue is not limited to computer connectivity. the phone goes into car mode on its own. car mode is triggered by a simple resistor in the car dock. different resistor values will put the phone in the different dock modes, Adam outler had a bunch on information on USB standards when he made his own captivate car mount. what is going on is most likely that a piece of semi conducive material is trapped in USB port on the phone or the port is otherwise damaged on the phone. there could also be some physical issue or calibration issue with the chip that controls the USB. I have seen similar issues on my own phone and seen atleast one post with issues identical to mine.
the seller sold it for a reason.
hello I have a doubt I can do as root, I infuse without odin or Heimdall, as my pc does not recognize my phone in download mode only gives me the error: Windows does not recognize the usb device, and try to install drivers kies , kies mini and samsung usb drivers

- Phone found on
- I have version 2.3.6 uclb3 stock

with another PC if it is recognized but I have no access to another for now
Oddly enough I just acquired a Samsung Infuse 4G this morning, and I've gone through 4 USB cables (that work perfectly with a number of other devices, all tested one by one this morning just to prove it to myself), I've gone through dozens of USB ports across 4 computers (3 laptops and 1 desktop), and no matter what I try to do and how many times I install/uninstall/reinstall either Kies/Kies mini/the USB drivers all by themselves, I cannot get any response from Windows (or even Linux) with respect to this Infuse and I gotta say I'm a bit peeved about it (not at anyone here, or Samsung, but at the person that sold it to me - my fault there for not checking it out completely).
It'll charge fine off the microUSB port, it'll even recognize that it's been plugged into a computer and ask what mode would I like (Kies firmware upgrade, Media, USB storage) and regardless of what I do in any respect, still nothing. Windows never recognizes it at all - there's no error message about not being able to use a device, it just doesn't "see" it ever no matter what's attempted - the classic "ba-donk" sound when attaching a USB device is never heard from any computer I've plugged this phone into, nor detached it from.
What pisses me off the most is the device is at pure factory stock condition, running Froyo 2.2.1 and I can't get it to update over the air to Gingerbread 2.3.6 in any respect - it'll connect with the AT&T servers but then it says "Your device is up to date" which obviously is not correct.
So I'm stuck with a device that's not allowing me to get it off the most basic stock build - if I could just get it to Android 2.3.6 I'd be much happier with it but, I don't see it happening and I have no idea how to proceed.
Don't want to try and dump it off on someone else now even though that would be pretty easy to do off craigslist, probably get $125 for it in no time flat.
Any suggestions as to how I can make it somewhat useful past that dreaded Froyo 2.2.1 would be greatly appreciated.
It's pure stock, not rooted, but it is unlocked as it works with a T-Mobile SIM installed when I tried it. Guess there's just no potential way to force it to update to 2.3.6... dagnabbit.
EDIT:
And no, download mode, recovery, nothing works outside of the OS either, the phone goes into Download mode obviously without issues but attaching the USB cable does nothing, it's just not visible to the computer in any respect. Seems a bit odd but whatever, guess it's just dead for USB data transfer at this point.

Did you ever find a solution for rooting your Infuse? I'm having the EXACT same issues with mine and would love to root it and move on.
I had the issue had to take it out of debug mode to get it to recognize even then only heimdall would recognize it in download mode

I don't want to get burn in on my phone, but I tried for 6 hours today to get this rooted and it was just one problem after another, most of which I see have barely happened to anyone. Between driver errors, installing driver errors, unauthorized adb errors, some strange error with a missing key or something, and it saying it's waiting for a device when attempting to run the boot image, I had to give up because everyone around me was getting annoyed by how much time I spent on it. A simple guide of maybe five things I had to do turned into a huge rabbit hole, it even resulted in my phone inconspicuously seeming as though it's bricked for a few hours for some reason.
So my question is, is there anything I can do? I'm a gamer, and I have OCD to boot, so when I see those damn icons burnt into my screen when playing something, it's gonna kill me. Is Tasker an option? Man, this was much easier on IOS, surprisingly.

Oh, sorry about that. Windows 10 Home. It's a couple years old now. An Acer Aspire 5. It has been giving me driver troubles for a long time, which would explain why it's made it so difficult to root.
The "waiting for device" is symptomatic of a missing driver.
There's a number of threads on installing drivers/connecting to PC in https://forum.xda-developers.com/f/oneplus-8t-guides-news-discussion.11585/
I even write one of them with lots of screenshots.
If none of them work then I suggest you have issues with your PC or, if you can't see your phone at all using MTP, your physical contention between the phone and PC.
Have you tried using a different USB port and USB cable? It's possible the port/usb cable is damaged and causing issues. swap both with a different USB Cable, make sure it's a thicker cable and not a cheap one. if you're using the C to C cable that comes with the phone, try using a USB C to USB A adapter.
Download full android SDK. Works for me every time.
