Hi everyone,
i'm having difficulties to connect my sgs2 to a pc.
i have tried it on 3 different machines (win7 64, win7 64, winxp 32) with the same problem:
I works fine when i first connect the phone in download mode. But as soon as i disconnect the cable i can't connect it again. Windows sais that it doesn't recognize the device and that's it. The device manager shows an "Unknown Device" under USB-Controller. And i am not even able to install drivers by manually pointing windows to a file.
as already sais, i have tried that on 3 different machines. I have tried installing driver via kies and via the driver file that is available here in the forums. i have also tried different usb ports.
Any ideas?
Goddchen
EDIT: Maybe this is an important information: the phone connects fine as long as it is running (can be found via adb, logcat is working, etc...) it only makes problem when in download mode...
I had exactly the same issue yesterday on my Windows 7 box. In the end I connected the phone in normal (not download) mode. Into device manager and uninstalled the drivers through there.
Then I uninstalled Kies and reconnected the phone, I allowed Windows to search windows update to find drivers (not that it did as it couldn't find any and reverted to the local ones. Then disconnect the phone, re-install Kies, run the install drivers from the tools menu, close Kies. Run up Odin and the connect the phone in Download mode, low and behold 2 minutes later after a lengthy installation process the phone was picked up.
I tried a number of things but for some reason this specific order seemed to sort it.
Hey,
thanks for you hints. But they didn't work for me.
I found the problem: believe it or not, it was THE CABLE. I went and got another cable and this one is working fine all the time. The other one doesn't... Very strange...
I installed the drivers for the phone (v3.0.0.007 & v3.0.0.017), rebooted PC since it wasn't working when I plugged the phone in, then plugged in phone which worked (couple devices showed up in device manager), fired up ADB which I already had installed for my OG Droid & Nook Color, "adb devices" returns nothing. Replug phone in, select HTC Sync for the method, verified USB Debugging was showing up, "adb devices" - still nothing. Now in Device Manager, I don't have any HTC Android devices like I saw a minute ago. Now I just have "Unknown device" and it won't accept the USB drivers from C:\Program Files (x86)\HTC\HTC Driver\Driver Files\Win7_x64. When I plug in the phone, it no longer prompts me what I want to do on the phone, it just connects USB Debugging and nothing else - no disk drive, no HTC Sync, no nothing. Rebooted PC & phone, same deal when I plug in the phone - it just has an "unknown device" and doesn't let me choose HTC Sync or anything. I made sure the check box is still checked for "ask me" under settings -> connect to PC.
I am reinstalling drivers now and am not going to install the full HTC Sync package. Maybe that'll work better. So far, it appears that the drivers and/or HTC Sync software are crap.
Unplugged phone
Uninstalled all 3 HTC pieces in appwiz.cpl
Installed v3.0.0.007 drivers
Plugged phone in
Got message about failing to install hardware
Device manager now shows: Other devices - Android Phone
It did this the first time I tried installing stuff and a reboot of the PC fixed it, so I'm rebooting...brb!
No luck still. Trying some more stuff. If anyone out there has any ideas, let me know. My phone still won't prompt me for action when I plug in the USB.
Uninstalled HTC USB drivers (v3.0.0.007)
Installed HTC Sync package, including HTC USB drivers v3.0.0.017 & USB BMP drivers
Plugged in phone - same problem
Running out of ideas. Might do factory reset on phone. Might try another PC.
OK I think I figured it out. You have to turn off USB Debugging. As soon as I did that, my PC found new hardware and the phone displayed the expected prompt. It mounted an E: drive and wanted to load TL-bootstrap.exe, which I didn't do.
When I go to the debugging options, it shows as already on even though I just disabled it. I uncheck it and recheck and it goes back to broken state - PC shows an unusable "Android Phone" under Other Devices.
Hmm...now what?
Had to go to a meeting, so I did a factory reset on my phone and set it to not sync, so it should be just like it was when I first got it from Verizon.
Without USB debugging turned on, the phone appears to connect to my PC properly, but HTC Sync says "no device connected" and the phone says "Unable to find HTC Sync on your PC. Please make sure that HTC Sync is installed and opened blah blah blah".
The only hardware that appears in device manager is a pair of "HTC Android Phone USB Device" in the Disk Drives section, as well as a 3rd one under DVD/CD-ROM Drives.
Since HTC Sync isn't working, I guess the drivers are completely failing. I hate crappy drivers. Might have to just mess with my phone from a different PC.
Now USB Debugging won't load at all. I toggle it on and off, disconnect and reconnect USB cable, toggle it again.....nothing happens. Seems to be going downhill quickly.
Uninstalled all HTC software again, including a WModem one that I didn't see before (could be leftover from rooting the wife's Incredible).
Plugged phone in to see what it does - pretty much the same as when all the HTC software is installed. That is, 3 drives mount when USB Debugging is turned off. Turning debugging on is working now, but there is no driver installed on my PC. However, it doesn't matter if I install drivers, it still won't use them.
Does anyone know if there is a special driver for Win7 64-bit?
I have Windows 7 x64 Pro at the office and home, and am using the drivers from HTCDriver3.0.0.007.exe just fine. Try doing a hard power cycle on the phone (power off, then on -- or yank the battery) and restart your computer. Use a USB port that is on the back of your motherboard or from a trustworthy powered USB hub (undervoltage will cause you all kinds of grief). Try another cable. Use charge-only mode, not HTC Sync.
Sorry for the spam earlier. Ya, it was just my laptop. My home PC is Win7 x64 as well and it works fine. Wireless tether is workin'. Loving the Rezound!
REPLY:ADB not seeing the device
yeahh i got so scared because ADB would not recognize my Rezound after Re-Flashing the Stock Rom because for some reason my phone suddenly kept re-booting over and over non stop.. so anyways.. i found a fix. well it worked for me at least. i re-installed the HTC drivers and then on the phone i turned "USB Debugging" On. then i plugged the phone to the computer, opened up CMD and when typing
"cd c:\android-sdk-windows\platform-tools\ ENTER"
"adb devices ENTER" it came back as
List of devices attached
HT19YS204824 device
Before it would say error. it worked for me. hopefully this is at least of some help
Need a little help here. I cannot get my phone to connect to my computer, I'm running Windows 7. I have kies installed and have also downloaded the drivers directly from the Samsung site, but still cannot connect. When I plug in, it says installing drivers, but then gives me an error.
If I go to Device Manager, I see SAMSUNG Mobile MTP Device but with the yellow exclamation mark. Under driver details it shows the correct driver installed, but has a Code 10 Error. "The Device cannot be started".
I've rebooted comp, rebooted phone, toggled USB debugging, uninstalled and reinstalled drivers, tried 2 different USB cables, and nothing is working. Anyone have any ideas?
I didn't have to do everything you listed to get it to work, but I did have to run the installer (T-Mobile_T999_GSIII_Samsung_USB_Driver_v1_4_6_0.exe) twice to get it to work.. it failed the first time.
I just unplugged and then plugged cable back in, ran the installer and installed again over old drivers.
You can also try going into Device Manager, right-click on the phone and "Update Driver Software" manually... installer extracts all drivers to the C:\Program Files\SAMSUNG\USB Drivers folder.
Still no luck. It installs the Samsung USB modem drivers fine and shows the phone correctly, but fails on the MTP Driver section.
Just for future reference for anyone that comes across this while searching. I did get this fixed. I tried a couple more usb cables and a friends computer with the same issues.
What I ended up doing was a factory reset on the phone. Plugged phone in after first boot and mtp drivers installed right away.
I plug my phone into a USB port.
The first time I did so, an AutoPlay window pops up prompting me to run LGAutoRun.exe. I click to do so.
The LG United Drivers are installed onto my computer great.
But then an AutoPlay window pops up prompting me to run LGAutoRun.exe. I click to do so.
My computer attempts to install MTP USB Driver, but fails. According to Windows, the device is unplugged.
The AutoPlay window reappears. Repeat from the beginning of the paragraph.
What have I done to deserve such trouble, LG?!?!
Apparently the drivers installed directly from phone are not enough. In any case, I was observing similar behaviour *until* I installed LG PC Suite (which you should have been prompted to do too). It's stupid, it sucks but again, it's LG.
Install the LG drivers first. After that, when you plug your phone, it will be recognised as an mtp device.
Have you got Windows Media Player installed?

I tried two different versions of the LG United Mobile Driver, versions 3.7.2 and 3.8.1 on my computer. Same problems.

I do. Same problems.
Plug the phone, go to device manager in windows and uninstall the driver for the phone( or whatever shows up with the yellow triangle). Then unplug the phone and connect it back again. It should work. If not, uninstall the lg drivers and clean every trace of them and start from the begining.

Tried uninstalling the LG U2 USB Driver, then disconnected and reconnected phone. Same problem. LG U2 USB Driver was installed but MTP USB still shows up as unplugged.
Then uninstalled LG PC Suite and LG United Mobile Driver, reinstalled LG PC Suite and reconnected phone. Problem still occurs. I run LGAutoRun.exe and United Mobile Drivers are installed. Same problem. MTP USB shows up as "device unplugged" and phone keeps disconnecting and reconnecting to computer, saying drivers were not properly installed due to MTP USB being unplugged.
Interesting to note the phone is listed as a CD-ROM drive.

Install the software from the CD image. It will load the correct driver. After this re-connect the device and the CD image will show up for a few seconds and disappear. After this the storage will show up. That is how it worked on my device.

I have already tried what you said as I posted before. The LG United Mobile driver gets installed but the MTP USB Driver does not get installed due to the device being unplugged according to Windows, even though I have yet to disconnect the phone from the computer. The phone still says "Connected as an installer".
The phone is recognized as an F: Drive by Windows but LGE Mobile but keeps disconnecting and reconnecting every 20 seconds or so.
I am going to have to upload a video to YouTube to make things crystal clear.

Try a different USB port or cable. My P769 would not work on my USB 3 ports, but was happy on the USB 2 port. I had already installed the drivers and LG PC Suite and it picked up each mode just fine.
Plugging the phone into USB 2.0 makes the phone show up in portable devices, but LG Suite fails to identify the phone. I tried using both LGE Android Net MTP USB Device and MTP USB Device but they both fail. I have LG United Drivers and LG Suite installed already.
got thesame problem here mate..i search all over here and google the driver but still cant find any solution..this is so frustrating to fix this issue,,got install and uninstall the pc suite and driver many times but still cant get the solution..so what could be the fix????
no one can suggest..someone told me that maybe its causing the broken data cable but i have 3 cables now..
everytime i intend to install the MTP driver thing my pc always failed to do so,,saying that the filename,directory name or syntax label is incorrect..but i manually direct the search to lg driver folder but same error occurs..or there still other alternative apps that can transfer files without removing my sd to my phone,or atleast transfer files over the wifi..??
Any fix for this one? Already tried uninstalling, installing LG drivers, removed and reinserted SD card and everything. But still to no avail. It installs everything successfully EXCEPT USB MTP device which is the one I needed the most. Any solutions? Thanks!

You must be on 64 bit windows. Not even on 64bit, Still try this...
1) Uninstall LG Drivers, LG PC Suite and anything you see named LG. Restart PC.
2) Install latest LG Driver from this post (step 4)
3) Install Optional MTP Driver from this post (step 4)
4) Open Windows Device Manager (just to watch whats happening.)
5) Disconnect Internet (To avoid stupid online WDM drivers)
6) Connect phone with Usb and let drivers install automatically. Give it some time to install drivers keeping watch on Device Manager window.
7) Keep changing USB connect modes to all modes one-by-one on Phone and let drivers install.
You should see MTP drivers installed now. If this does not help, cant think of anything else. If this works, press THANKS button
EDIT: Connect USB at backside of pc, directly to USB on pc motherboard.

Thanks for taking the time to answer me mate. Already tried literally everything on what you just said above. Still no. I tried it on my brother's old vista laptop. One connect and it worked instantly! Lol.

This works on XP x86
Need:
1. LG USB cable that came with the phone,
2. Media Player 10/11 preinstalled,
3. your LG Driver,
3. LG Phone,
4. and Media Transfer Protocol Porting Kit (mtppk12.exe)
1. with phone disconnected install Media Transfer Protocol Porting Kit
2. when asked to restart the PC, go ahead and restart
3. open device manager, connect phone to PC
4. install driver and watch LGE Android MTP disappear
5. be sure to toggle between Charge and MTP on the phone to install all drivers
this also works for HTC MTP
Hi,
After the most recent update (OTA), when I connect my phone to my PC, regardless of what mode I have the USB set for on the phone, I can no longer connect
to my phone.
It worked flawlessly before.
The Huawei HiSuite also cannot connect (although I don't norm ally use that anyway).
I have tried reinstalling ADB and also HiSuite to no avail.
One thing I do notice is that there was a HDB driver missing. When I rebooted my PC it has now changed to 'USB Composite device' but shows the error
Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)
{Bad Image}
%hs is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0x
I've tried to automatically install a driver, again no joy. (Because the device is not recognised, it just says it could not a find a suitable driver).
If I uninstall the device and then plug my phone back in we then start with the HDB device (for which there is no driver according to MS), which upon reboot becomes the 'USB Composite device' again.
So, anyone know how I can fix this? I'd like access to my phone through my PC if possible.
TIA (Thanks in Advance)
I know it's obvious, but have you tried a different usb port.

Yes. Front and back of PC as well through a hub.
It makes a sound like it connects, then I get a popup on my phone "Charge only / Transfer files / Transfer photos" and regardless of which one I select, it then disconnects.
Somewhat annoying. It worked okay before latest update.
I've even reinstalled ADB, even though I'm fairly certain this has nothing to do with it.
Thanks for your reply anyway!
[Solved]
I managed to solve this by plugging in my Honor 9. On the device manager page in Windows take a look at the 'USB Composite Device' item and selecting with an exclamation mark against it and right click it and select"Uninstall device" from the menu. When it asks to remove the driver, select yes. Unplug your phone. Reboot your PC. Upon plugging your phone back in, your device will be re-detected and Windows will install the driver correctly.
