[Q] LG G2 USB Not Recognized

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.

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 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?

Updating Yotaphone 2 YD201 ME Build

Dear all, I'm new here and just got my yotaphone 2 today, bought it locally from UAE, i beleive that the build ME refers to Middle East, got an android version of 4.4.3 YD201 model.
I thought that YD201 models are OTA updatable versions but seems not
Please can you guide me in a simple way how to update to lollipop? Noting that I've never flashed or done this before
Thank you so much..
https://forum.xda-developers.com/yo...grade-yotaphone-2yd206-running-4-4-4-t3506293
You can follow this guide fully but you don't need to flash HK first, so you just flash RU 5.0.0 firmware directly.

Thank you so much.. Totally appreciate that.. But I don't know if it really matters as the tools relates to YD206 while I have YD201.. Should I proceed ?
By the tools do you mean YotaphoneFlasher? It works on both 201 and 206 since it's from official.
Thank you again.. OK I'm all set everything is ready but the only thing that's keeping me is drivers installation... Somehow the Google drive coming with the flasher is not being installed. I tried all ways possible, I.e. right click on the INF file and install but I get error message, and also tried to install it from device manager but couldn't. Can you please help with this? Thanks again
Btw I'm using Windows 7

my dear friend, i managed to update the driver, thanks to you, but it seems that when i power off the phone and enter the "downloading " mode on the phone screen then connect it to the computer it seems the phone is not being connected.. i used the flasher chosed option 1 "flash the cellphone" then i get the message "waiting for device" on the flasher..
i had a screenshot just to show that i have done everything i should (i guess) .. i.e. copied the firmware.. etc,,,
mindyou, i think the problem is that when i conncet the phone to usb it goes under other devices/Android which is not being recognized..
you are the best and thank you for your help again and again!
Weird. Do you've already install both drivers and restart your computer?
If yes, how about try to plug another usb port?
I got both ADB and Qualm drivers installed.. but nothing happening! I tried the 3 usb ports already..
I don't know how to solve this.. I think I need to try it on another computer .. maybe it'll work out!
Your driver not properly install. Try reboot pc, enable usb debugging at phone, plug in usb. See if there is any changes at device manager.
There is yellow triangle. So it mean.. Oh.. Oo..
If stilk not ok. Plug out usb from pc. At device manager, unsinstall both yellow triangle. Plug in back usb. So it will detect device and windows trying to install it.
If you have Windows 10 you have to disable signature driver verification, entering in the advanced boot menu of windows. After that the .inf driver will install.
I got the update at last and it's working beautifully smooth I downloaded universal driver from adbdriver.com and it worked perfectly. Thank you all guys for your help and efforts

Samsung A5 (A-510M) PC does not recognize "failed to find /misc partition"

Hello:
First of all, excuse me, I'm using a translator because my English is not very good. I was using a custom rom and wanted to back to stock so I flashed the correct firmware for my model (A-510M ARO NOUGAT) via ODIN. The process ended and had no errors. When I turned on the phone and connected it to my pc and it does not recognize it, it only charges the battery. I tried to format from the recovery and it shows the message "failed to find / misc partition"
- I tried with other USB cables.
- I tested it with other USB ports.
- I've updated Samsung drivers.
- I tried the secret menu and it does not work.
- does not recognize the download mode either
- I can not use ODIN to reinstall the firmware.
- Samsung Kies does not recognize the phone.
- Does not recognize ADB mode
The truth is that I am desperate and I do not know what to do. I can not reinstall the firmware if the PC does not recognize it. If anyone knows a possible solution I am very grateful.
thanks to all
i came across your situation long ago. it is the pc that doesn't recognize your phone. try with different pc. also you can try to format using settings>backup & reset menu. I ended up resetting my pc in order to recognize my phone.

No worries. We don't have misc partition so it's normal.
FRP lock won't reset on firmware flash. You need to enter your google account on boot.
To disable frp lock before factory reset next time, either remove your google account from your phone, or disable screen lock before reset.
You can't flash new firmware from download mode if you are in frp lock.
