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.

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.

Anyone has an idea how to fix this problem?
same problem
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?
Hi, I have strange problem with my OP2. Since some time when I connect my OP2 to PC it's only connected in charging mode. I've tried different methods to solve it: tried different cables, tried different computer, event wiped data & cache but nothing seems to work. It seems that it might have something with OOS 3.1 or eventually there is some hardware issue with my phone. Currently I'm on stock OOS 3.1 without root and on stock recovery. Is there any way to root my phone without possibility to connect it to PC in ADB/Fastboot mode? Or what else can I try to make phone to connect to PC in different mode than charging?

Connect your device in fastboot mode to your pc and go to device manager in your pc you will see a device listed as Kedacom USB device. Uninstall and delete the driver. Remove your device and connect it again.

No I haven't found anything new. After update to 3.5.5 still same situation. I think this is some kind of hardware malfunction. Have you ever used charging cable other than shipped with phone? I think maybe using other cable damaged something with usb port in phone...
My phone is Xiaomi. My phone recently have been infected by viruses that destroyed some important apps like: Play Store, Google Play Services and etc. I turned it off and then, wiped all data of it. The first configuration is actually broken in the step "Connect in the MI Account", so i tried use fastboot to activate USB Debug and define home as the default and press home button through ADB. But in the first step... My computer not found it.
My Xiaomi is Redmi-2014819. I need a answer most fast possible.
Lg G6 with the same issues. Fast charge went crazy and think this has blown something inside. Only normal charging works.
No ADB, fastboot, download mode. Can't even connect to laptop or Mac to transfer files.
Had charger replaced but it's the phone I think.
Gonna replace charge port but don't think this will fix issue.
Anyone had any luck?

Have you tried a different cord? If its not the cord the inspect the port on your phone to make sure no lint or crud is physically blocking some pins. Do you have developer options enabled? Maybe something got changed in there. Its never happened to me so these are just guesses. Maybe somebody smarter can help.

Mine gives a notification that the phone is charging when I connect to computer but if I click the notification it gives me the option to transfer files instead. You do have USB Debugging enabled on the Developers Menu, correct?
Hello guys
I have the same problem on my phone i tried everything i found on google and other forums, and the last option that i couldn't do is to send my phone to replace the usb port, but i have no warranty as i bought it already used. It's a shame that no one can find a solution here especially that the other forums at least tried to fix for some people but not here on xda which is the first in the world.

I've even changed my USB port and daughterboard twice. I am stumped. I got 3 laptops 2 running 10 and one running Ubuntu and mAid along with a tower running xp. I fix unfixable phones and resell them. I've tried EVERYTHING. I know this is an old thread but Any help would be appreciated.
Hi,
since one of the latest Oxygen OS updates, my OnePlus 5 is not able to connect to any PC anymore as long as USB-Debugging is enabled. It's not showing up in Device-Manager nor lsusb on multiple PCs, I've tried rebooting multiple times, safe mode, clearing settings data, but nothing seems to have changed it's behavior - when turning on USB Debugging, all USB connections seem to get lost, including data and charging. A curious thing I noticed is that the Android-System notification that lets you switch USB modes sticks around when unplugging in this state, even after disabling debugging again, until the phone is restarted.
Is this a common issue? I haven't been able to find anything about it on XDA or on their official product forums which seem to be pretty dead, but it's a pretty big problem for me since I need this phone for app development.
Thanks!

I'm running the current stable Oxygen OS 5.1.5(ONEPLUS A500_23_180808), unrooted. I'll try installing the new beta, since fastboot mode still gets recognized by PCs.
Ok, so beta 19 didn't change anything about it - still the same issue and behavior when unplugging. Not sure what else to do other than trying to wipe it, which would be pretty annoying
I have the same problem and I can not solve it neither with usb debuginc or mtp and I see that Oneplus is not bothering att all about this problem. I need to transfer some data from my computer to my phone and I am stucked. I am thinking sending to warranty or sell it! I was a big fun but now........

I've tried this a few times, the options in that pop-up don't have any effect whatsoever after enabling USB debugging and unplugging/plugging the phone back in. Also tried changing the default setting, which doesn't seem to have any effect either though.
Same for me. No effect att all. I don't lnpw what to do. I have a lot of files in storage and I can not root my phone and try another Rom.
Help!!!
I have done all the possibel combinations.

Really strange... OOS 5.1.5 and OB19 and before.
Never had any issues and also others not report such issues
my nexus 6 will only charge no data transfer and pc wont recognize it. When i connect it to the pc it goes staright to charge mode and the usb trident symbol doesnt ever appear. In developer options usb configure is stuck in "charge mode" only. Ive tried different roms from pie to mm . i reinstalled bootloader and radio, tried twrp back ups and still the same. Had new charging port put in phone thinking that was the problem but didnt help. Ive searched google but couldnt find anything. Any Ideas, really appreciate it thx
When I installed stock rom which was android 7.1 it changed phone back to encrypted. Now i have to format internal drive in order to install a pie rom. Does anyone think that formatting internal drive might fix problem with not being able to do anything but charge phone from usb port, because if that doesnt fix it there would be no way for me to put any rom on my internal drive to install it.. Does anyone have any suggestions

Just to double check that adb devices shows your serial #. If not, it may be a driver issue.
Computer doesn’t see it, when I enter adb devices it doesn’t show up. Nothing shows up in device manager either: Also when I enter fast boot on the phone “power lower volume button” it says “connect usb data cable” I’ve trued numerous cables that work fine on my other phone. So it’s not the cable. After I plug them into phone it still says connect usb data cable.
I also have a thumb drive with a micro usb connecter that used to work on the phone. Now the phone doesn’t see it when you plug it in to the phone. But it works on my other phone so it’s not the thumb drive

It sounds like a driver problem. Is it a windows PC? Have you tried installing the Google USB driver? I've had similar issues, and reinstalling the driver(s) has worked for me.
It’s windows 10 and I reinstalled driver, other thing is in my car when I plug it in to the usb slot for android auto, it doesn’t show up in my car either and it used too.
It’s like the phone is stuck in charge only mode and I can’t get it out of that

When you connect your other phone to your PC, does its serial # show up in adb devices? If so, I'm out of suggestions.
1 more thing.. Have you enabled USB debugging in Developer Options?
Other phones shows up and in devolpers options in “usb configuration” you can set it to mtp but when you hit enter it goes back to charge only. I was on” aiop 14.0 rom” when it happened but it was working fine on that rom , then one day android auto kept saying connect usb, so when I got home I tried to plug it into pc and nothing. So I replaced charging port thinking that was problem but it didn’t help. Flashed other roms and even went back to stock, reflashed bootloader nothing helped. I was hoping someone here had seen this before cause I googled it and nothing like this could I find

Forget USB configuration for a minute. In developer options, under debugging, USB debugging needs to be enabled.
usb debugging is enable also. even tried turning it off and back on again, didnt help.
you know when you connect phone to pc and you normally see the usb trident symbol on your phone, well when i connect it to the pc i dont see that symbol it just goes straight to charging but even charging i should still see the usb symbol and i dont,
