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!

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.

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?
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.
Hey everyone,
recently I got a YU Yureka (bought it 2nd hand), and it was all working very well. I installed a custom theme pack and was enjoying the phone for hardly one day. Things started to go wrong when I thought to root my phone. So I plugged my phone into the PC. But the phone wouldn't show. I tried different cable and different ports but couldn't get it to work. It won't even show in the device manager. No android device or No other troubleshoot devices were found in device manager. I tried unplugging and re-plugging while device manager is on screen, and I didn't noticed it refreshing or detecting the device in anyway. I also tried enabling USB debugging and tried to turn it on and off but still no luck. The phone is charging when connected to PC but its not detecting as a device. When I selected USB connection mode in Settings>Storage, it says 'USB is now disconnected'. So I thought I would do a simple restart and see if fixes the problem then came the worst. My phone is now kind of soft bricked. I said that I installed a theme pack before, and I think that was the problem. The theme had replaced my bootlogo so that might have been the problem. So I wiped my device in recovey mode and restarted. Now my phone is not turning on, Its stuck at CYANOGEN screen. The Worse Case Scenario - I can't even flash stock rom cause my phone isn't connecting to PC not even in Fastboot. I'm totally screwed.
Well I don't know if its a hardware issue. and if someone had this issue earlier and solved it, please share your solution kindly..
Thank you

Fixed. It was a hardware problem. Phone is working perfect now
what is real problem i can't say , but if you want to detect your phone by windows automatically ,
shut down your system , unplug power of your computer from main board / turn off ups > unplug ups from main switch > wait 2 minutes .> now in phone developer options > enable android debugging > restart phone > connect phone to pc with usb cable and now plug your computer power in main switch > start your computer that's all
Install windows media feture pack in the computer

I really hope you found a solution. Ive been looking an answer for this annoying problem for 6 months!
Ive read almost 50 threads in differents forums about this problem but no solution at all.
- Tried changing charging port. Cost me a few dollars but no solution.
- Tried USB debugging on and off from developers menu.
- Did MTP+ADB option in *#*#0808#* menu.
- Turned Low Battery Dump "on" in *#*#0808#* menu.
- Tried 10 or more different original Samsung cables.
- Upgraded PC USB drivers.
None of them worked for me.
Hope you have made a progress.
