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.

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.

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?
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.
Hi XDA members. I need your assistance.
My phone has been acting up lately. Plugged in to my laptop using the type C cable that came together with the phone and the message USB device not recognized pop-ed up. Tried re-updating the drivers @ Device Manager, but still, the problem persist. Tried changing laptop and still, the problem persist!
Before this, I can easily transfer my stuffs from my lappy to my phone and vice versa. But now, even the status bar menu option to choose "Charging/Transfer file/etc" isn't appearing..
@ Device Manager, under the Universal Serial Bus controllers tab, it's written there "Unknown USB Device (Device Descriptor Request Failed) .
My mi a1 is rooted and is on Jan update btw. Wanted to unroot & flash stock fastboot image to update to Feb update, but if I can't even connect to the pic, how am I suppose to use the MiFlash Tool?
Please help.. Feeling so restless now :crying:
Edit : Tried every method I've read in the internet, from updating drivers, unplugging power source, uninstall and re-install drivers. The only thing that I have not tried is changing cable. If it works after using a new cable, then please kindly ignore this thread/remove it please moderator. At the same time, wondering if root process has got anything to do with this..
Edit : Found the issue. It is the cable all along! Changed to a new cable and everything works fine.
Just had the exact same issue here, found your post, changed cables and everything is fine again. Thanks
Same issue with Mi A1
Hi,
I'm facing the same issue. My Mi A1 is not recognied on laptop running Windows 7 64-bit. Earlier it used to work without any problem.
My Mi A1 is running on Android 9 with Sept 2019 updates and it is not rooted.
I've tried changing cable and with developer options on and off. Nothing working.
Any suggestions to overcome this issue.
Best,
1. it happens when you had faulty cable.
2. your phone's usb port is faulty
first replace your cable if problem persist clean your phone's usb port and if both not worked repalce your phone's usb charging port
I'm happy that you already solved the issue, but for future reference:
1) If it has already worked on that PC, probably the cable is not a data cable but a charge-only cable (~faulty USB cable, but not really)
2) If it has never worked it's possibile that is a driver problem, use this tool to install ADB, Fastboot and Drivers: https://forum.xda-developers.com/showthread.php?t=2588979
3) Unlikely, but possible, you entered the network Diagnostic Mode. Just turn off debug/restart the phone.
i have the same issue. I also tested on other PCs. I have laptop with w7 x64, it also doesn't work on w10 x64 too. When i connect A1 to pc, nothing happens in the device manager. The phone is just charging. I have debugging as on and default configuration usb as transfer files. Version os - 10.0.0.12 with unlocked bootloader and root.
The cable is good because in the previous month it worked on it. Please help me with this.
I have same problem. My phone memory is full and I have to transfer files to free it up. Some one please help. I wonder if this has to do with the security update done recently.
same problem here, recognizes nothing, only the load works...

Check your socket - usbc, I had a damaged socket, I gave it back for warranty and changed it. I was just charging the battery.

How about hard resetting the device, will it work
This must be a generic flaw with the Mi A1 as mine is doing exactly the same. I suspect it's the USB-C port itself as it's got steadily worse over the months. I have an Outlook task to remind me to backup my phone using FreeFileSync. Everything is backed up anyway to the cloud but I do like to keep a copy of the high resolution photos as Google reduces quality with the free unlimited photo storage option.
It's charging fine so not too worried. Just need a different way to transfer the photos off the phone. I do have access to a business OneDrive account.
Working in IT, I'm not the world's biggest fan of the USB-C port. It's not as robust as the old USB-A port.
Hi, I really need help. three months ago, some weeks after my Mi 9T overheated on sun (don't know if that has some relation to the issue), it suddenly stopped charging while on, unless I rebooted or turned off. Also, it had difficulties to transfer files to PC and connect to a flash drive by OTG.
Then, I took it to a guy and he said I needed to replace the charging port, and so I did. But only now, after a serious issue. I was changing my rom from MiRoom (MIUI 12) to Evolution X, since the MiRoom's developer ended the rom's support. But It didn't work, It boots into Fastboot mode. I tried to connect to PC and OTG, on recovery mode, but neither worked. The PC doesn't recognize my phone, and the OTG flash drive isn't recognized by the phone.
I bought the charging connector online and paid that guy to replace it. The port feels better, the connector feels way steadier when pluged in, but I still can't know if it charges while on and file transfer to PC or OTG is still not working. So, I'm stuck on recovery mode, in a rom that doesn't boot and a USB port that doesn't work properly. If anyone has a clue of what part I might take to replace or a repair, or maybe a software solution, if that's the case, I would be really thankful.
