Hi guys,
I have a massive problem.
I recently updated to 4.3 rooted etc, after a few days of not using my nexus 7 on the pc I wanted to flash a new rom.
Now my N7 is only shown as an "Unknown Device" in my Device Manager.
I tried to deinstall Drivers, install, everything, I tried every possibilty in Wug's toolkit, nothing worked. I also tried it on another Notebook where i have never connected any mobile device, same message and i'm not able to install the drivers.
I also tried several ports and cables(the original one included)
Here is the message:http://i.imgur.com/tgxOeZQ.jpg
Translation: The optimal driver software for your device is already installed.
After this I flashed back to 4.2.2 (downloaded the rom on my N7) while performing a normal factory reset, I can't wipe everything because then I am not able to flash anything.
So after flashing to 4.2.2 my N7 was shown as a portable device in my device-manager. I then turned on USB-Debugging to stock+unroot, it was then shown again as a Unknown device, in both modes, USB-Debugging turned Off and On.
So now my question, is there a solution to this? I searched for possibilites to get back to stock without USB but most of them were a bit sketchy or had dead links. Please help me (sorry for my bad english)
Edit:
I just the cable of my old Motorola Defy, and it randomly connects and disconnects(still shown as unknown), so basically I think it is possible that my USB plug is broken(it takes about 6 hours to load the battery which I think might be as well a reason for a broken USB plug).
But to send it back to Google I need to Stock Unroot first so here my problem is again!
greetings
Trying to connect my LG G2 to my Acer Aspire V laptop and I cant get anything out of it. I've installed the drivers from LG's website, I've tried installing LG pc suite(works via wifi. The phone thinks its connected via usb but the software doesn't see it). I've also tried manually selecting various LG drivers and it still won't come up. My laptop is windows 8. On my windows 7 desktop the first time I plugged it in it came up like a usb drive and connected perfectly to LG Suite.
Any suggestions? I am with bell.
bump~~~~~~~
bump............
Other than trying to completely deinstall all drivers, software, and then installing PC Suite again, I don't think there is a lot you can do.
Does Windows give any sort of notification about Device problems, or failing to install drivers?
Hi, background is this..
I have a D802-10C G2 that i rooted the stock 4.2.2 rom a while back using the post chinese method. Easy enough, all worked fine. no complaints. A couple of weeks ago i got offered the OTA 4.4 update, this failed due to the root. I then removed the root using the feature in super su. that seems to have worked as no apps or file managers etc could get root access. However, the OTA still wont work.
Now my problem is my phone will no longer be recognized by any operating system, on multiple computers. I have tried many ADB drivers, Windows 7 wont even detect the device, i've used every PC connect mode, USB debugging. However always the same result, it's as if i'm plugging in a blank usb cable into the computer. Nothing at all.
The only thing that does happen when i connect the phone to a computer is the phone starts to trickle charge. There is nothing detected in Device Manager in Windows 7 I've tried connecting in download mode, nothing. I've tried the LG support tool, PC sync. Nothing.
WiFi does connect to the PC suite fine BTW and other than that the phone is working perfectly. I've also tried connecting multiple usb cables on multiple ports.
I haven't been able to find a single case of the same problem in the week or so i've been looking. Hoping someone can help, i'm thinking i may have soft bricked my phone. I really do not think this is a driver issue.
Any help would be great. cheers

YOu can try checking the device manager or use other USB port on your phone.

The problem is not like the usual ones you will see about "computer not being able to see device" I don't think it's a driver or software issue, or if it is it's unlike any i have found in the weeks i've been searching the net for a solution. Here's why....
When i connect the phone to Windows 7 and 8 ( on 3 different computers) No hardware is detected, nothing in the Device Manager, no yellow question marks indicating 'Unknown Hardware'. Nothing, all it does is start trickle charging.
Now even with no ADB, or any driver at all installed, the computer should still detect the phone. Mine does not.
The same thing happens using OSX and Linux Mint 16 (again multiple computers) No devices or mounted or volumes shown at all. Linux terminal command "$ lsusb" does not list my hardware.
This is why i'm pretty much convinced that there is something wrong with the USB port on the phone. Because, if Linux can't see it then surely it's a hardware problem right?
The only other thing i can think of is, i have messed up the phones firmware while trying to unroot it? but only because the timing of all this is just too uncanny.
I think i'll have to suck it up and admit defeat here. Funny thing is the phone works perfectly and charges fine.
Stuck on 4.2 , with no ADB functionality. Perhaps i'll sell it cheap to someone who doesn't care.
Cheers for the reply mate.
Same problem here!
Only my G2 is not rooted, it is still on factory OS and recently updated to 4.4.2.
I have tried on several computers, different ports and no help.
On the first connection to a PC not connected before windows reports "USB device not recognized" problem.
After that every time I connect the phone to the same computer the phone itself only recognizes that it is using USB charging mode, it does not recognize the computer connection (known by the USB ison on android system tray) even with "Ask upon connection option checked".
Even when I manualy change the Android mode in Settings --> PC Connection from MTP to PTP or even LG software, nothing happens.
Definetly there seems to be a problem with the phone, but I don't beleive it's a software but a firmware problem.
Please help if anyone knows what to do.
same thing happened after installing T-mobile rom thrugh twrp. but my device boots into fastboot and i tryed falshing :
laf.img, boot.img, aboot.img, recovery.img, laf.img
but after reboot my LS980 dissapear from device manager and stucked on LG logo.
Dont know what to do now.
I'm no expert, but given there are a lot of them here and none have weighed in on this with any ideas for a fix, i'm going to assume it's a hardware problem.
Anyone else agree? Hardware problem not software?
Cheers
I guess that you already wiped everything right? Apart from that, i'll suggest you to go to some tech supp and ask them if they can verify that each pin of the micro usb is properly working.
Sorry for my english, hope it helps!
Sent from my LG-D802 using XDA Free mobile app
I will try to check the connector although i dont think that it is a hardware issue.
BTW I can enter the download mode after flashing the mentioned partitions and i can also enter the stock LG recovery but when i do the factory reset it keeps showing Factory reset processing ... for ever
It has happened to me the same thing :crying:, and is a problem with the boot.img, if by chance your G2 version 4.4.2 and the the 4.2.2 boot.img, goodbye.
The only solution is to take it to repair a service official, there will change you the card, with the consequent change of IMEI.quent change of IMEI.

Sirs, I flashed the baseband (https://www.androidfilehost.com/?w=files&flid=12880) then it got working back.
solved for me
I have some kinds of that problem, let try:
Settings -> General -> PC Connection -> Select USB connection method -> Media device (MTP) (or whatever)
Got this same issue after flashing cloudy g3 rom. Then later flashing dirty unicorns, which requires jelly bean baseband. But even restoring g3 and 24a baseband, still doesn't work. No pc tethering and no on the go usb. My usb port is basically charge only.

I have a LG G2 . recently updated from vs98027a to vs98039a 5.0 lollipop. Since the update my computer won't recognize my device in download mode and I don't have superuser ppermissions. Help plz
I also have the same problem.
It happened when I tried to backup info through LG PC Suite: the phone disconnected during the process, and now it's not recognized by any PC (http://forum.xda-developers.com/lg-g2/help/lg-g2-recognized-windows-backup-t3155323).
Also found a description of the same problem here: https://www.reddit.com/r/lgg2/comments/2urpnw/lg_g2_usb_only_charging_not_recognized_by_pc/ - no solutions, too.
Did anyone manage to fix this?
Okay. Hi guys.
I'm having some horrible USB connection problems and I've no idea whether they are hardware/software. I'm leaning towards the former.
About a month ago I noticed while plugged into my charger, my phone wasn't charging. Wiggling the cable did little, if anything to help. But it only happened that one day, and after a few beeps and boops of connections coming and going, it had seemed to have fixed itself.
Yesterday I decided to upgrade from XtreStoLite KitKat to XtreStoLite Lollipop. I made a bit of a mess of it and accidentally wiped my entire OS/cache/data before even putting the ROM on the sdcard directory. Fortunately I had already upgraded the modem/bootloader and was able to sideload the ROM.
I say I was able to sideload the ROM successfully, but this is really where the issues started to resurface. The first dozen or so times I tried to sideload I got "ADB not recognized" errors in CMD. I tried all sorts of USB driver re-installations, and installing google USB drivers from the Android SDK etc and nothing was working. Lots of beeps and boops of drivers installing and USB connections being made. In a last ditch attempt, I went back to CMD and once again typed "sideload adb rom.exe" and by some random miracle it worked. But that was the LAST time. I tried again later and got the same error as previously.
Anyway... new ROM installed. I ran through the set-up process and plugged my phone in to transfer over the add-on pack so I could re-activate Samsung Kies connections in order to restore my apps/photos etc.
*B-beep-b-b-b-eep-boop-b-beep* The phone was wildly connecting and disconnecting. I unplug it, blow into the USB connector - try to see any bent pins, but can't see anything. After a few tries I get it to connect long enough for me to transfer the file. Kies reinstalled. Throughout this WHOLE process there has been FAR too many disconnects.
If I DO get my phone to connect - Kies is stuck eternally on "connecting". I have a feeling MTP mode is just broken - as NOTHING shows up in My Computer when in that mode. Odin 3.09 no longer sees my phone at all, and when I connect in Camera mode NONE of the .zip files I placed in the sdcard directory show in Windows at all. But they ARE there, as I can still install from .zip in recovery.
The phone seems to work fine. But I want to restore my Kies backup, add/remove the .zips in the main sdcard directory, and see my phone in Odin.
Please help me. I am scared.
Guys could anyone help me?
My phone is Samsung A8 variant A800i non-rooted and already 6.0.1.
Eversince I upgraded to MM thru ODIN I am encountering an error in my OTG as in it won't read any disk... the only resort to make the otg work again is to reflash my phone. However during the most recent otg failure, a "USBsettings has stopped" was shown. I factory reset my phone but still this notification appears everytime I start my phone. So when I decided to reflash my phone, I was shocked that my laptop only charges my phone. It can't even detect my files thru mtp connection.
I tried the following and my laptop still can't detect my phone:
1. At the Developers Option I tried to switch the USB Configuration from MTP to Charging to MTP and various other switching, while connected and unconnected to laptop.
2. Dialled *#0808# to reset USBsettings but I am only getting "USBsettings" has stopped.
3. I reinstalled the USBsettings.apk from the system folder (via total commander).
4. I have installed USBsettings.apk taken from another phone.
By the way before I tried the above methods I have already eliminated the cable and pc problems since using the same cable and laptop, I can connect my other samsung phone thru mtp and is detected by odin. I have also tried various other desktop on Windows 7 and 10 but still the same problem: these only charges my phone.
Moreover, there is no abnormality in my charging time eversince this happened.
Hope someone could help me make this work again.
Thank You.
