idk full wipe after update? Didnt have this problem on mine

First restart your Pc then explore device management and see how your Pc read and recognize your device. Just check with right mouse and at list you can try to update manually the drivers from computer then choose MTP USB device and after the right drivers installed before.
How did you update nougat, with OTA or manually?
You should reset your device bakup & restore and try to connect again your phone , in case you installed manually nougat.
Lgup didn't recognizeize your devise maybe Lgup with Uppercut does!.

Try this... In Device Manager right click the yellow triangle and choose update driver. In the new window that opens up click on "browse my computer for driver software". After that click on "Let me pick from a list..." and in the following window you should have an option MTP USB Device. Click on that then on next. You should have everything working now. Good luck!

[Q] Help me, i cant connect X10i with my PC (Win7 pro 64bit)

i downloaded SE PC companion, but i cant connect to my PC to updrage Android 2.1,

Incorrect. You shouldn't mount the Phone for flashing. There you need to be in Flash Mode (Pressing the back button while powering on the device).
I'll go for the obvious, have you tried reinstalling PC companion? If is says device not recognised it could either be damaged (phone or usb port) or the drivers haven't installed properly (more likely).
So try a different usb port and go though the steps on PC companion and connect the phone only when it tells you to and it should install the drivers correctly or try going though the repair phone procedure without the phone connected (gives instructions). Think it installed different drivers for flashing.
same problem do you find solution
try this
try to download a driver named SEMC_Signed on your pc
after that connect your mobile
before you install this driver go to Mycomputer right click choose Manage then from the new screen choose device manager after that choose Universal Serial Bus, Uninstall any driver related to SE
Hope it works with you as it works with me
i dont know hoe to upload the file SEMC_Signed here
I've got the very same problem, although a bit more advanced. It started out this way then the phone stopped being able to charge too.
It's the USB port and something to do with the solder joints not being very good/strong enough to the main board and pulling off, especially on earlier models of the phone.
It seems to be a very common problem too with the only options being repair to the port and mainboard or replacement of the phone.
I'm awaiting my new phone right now.

Problems with MTP USB Device

I plug my phone into a USB port.
The first time I did so, an AutoPlay window pops up prompting me to run LGAutoRun.exe. I click to do so.
The LG United Drivers are installed onto my computer great.
But then an AutoPlay window pops up prompting me to run LGAutoRun.exe. I click to do so.
My computer attempts to install MTP USB Driver, but fails. According to Windows, the device is unplugged.
The AutoPlay window reappears. Repeat from the beginning of the paragraph.
What have I done to deserve such trouble, LG?!?!
Apparently the drivers installed directly from phone are not enough. In any case, I was observing similar behaviour *until* I installed LG PC Suite (which you should have been prompted to do too). It's stupid, it sucks but again, it's LG.
Install the LG drivers first. After that, when you plug your phone, it will be recognised as an mtp device.
Have you got Windows Media Player installed?

I do. Same problems.
Plug the phone, go to device manager in windows and uninstall the driver for the phone( or whatever shows up with the yellow triangle). Then unplug the phone and connect it back again. It should work. If not, uninstall the lg drivers and clean every trace of them and start from the begining.

Tried uninstalling the LG U2 USB Driver, then disconnected and reconnected phone. Same problem. LG U2 USB Driver was installed but MTP USB still shows up as unplugged.
Then uninstalled LG PC Suite and LG United Mobile Driver, reinstalled LG PC Suite and reconnected phone. Problem still occurs. I run LGAutoRun.exe and United Mobile Drivers are installed. Same problem. MTP USB shows up as "device unplugged" and phone keeps disconnecting and reconnecting to computer, saying drivers were not properly installed due to MTP USB being unplugged.
Interesting to note the phone is listed as a CD-ROM drive.

Install the software from the CD image. It will load the correct driver. After this re-connect the device and the CD image will show up for a few seconds and disappear. After this the storage will show up. That is how it worked on my device.

I have already tried what you said as I posted before. The LG United Mobile driver gets installed but the MTP USB Driver does not get installed due to the device being unplugged according to Windows, even though I have yet to disconnect the phone from the computer. The phone still says "Connected as an installer".
The phone is recognized as an F: Drive by Windows but LGE Mobile but keeps disconnecting and reconnecting every 20 seconds or so.
I am going to have to upload a video to YouTube to make things crystal clear.

Try a different USB port or cable. My P769 would not work on my USB 3 ports, but was happy on the USB 2 port. I had already installed the drivers and LG PC Suite and it picked up each mode just fine.
Plugging the phone into USB 2.0 makes the phone show up in portable devices, but LG Suite fails to identify the phone. I tried using both LGE Android Net MTP USB Device and MTP USB Device but they both fail. I have LG United Drivers and LG Suite installed already.
got thesame problem here mate..i search all over here and google the driver but still cant find any solution..this is so frustrating to fix this issue,,got install and uninstall the pc suite and driver many times but still cant get the solution..so what could be the fix????
no one can suggest..someone told me that maybe its causing the broken data cable but i have 3 cables now..
everytime i intend to install the MTP driver thing my pc always failed to do so,,saying that the filename,directory name or syntax label is incorrect..but i manually direct the search to lg driver folder but same error occurs..or there still other alternative apps that can transfer files without removing my sd to my phone,or atleast transfer files over the wifi..??
Any fix for this one? Already tried uninstalling, installing LG drivers, removed and reinserted SD card and everything. But still to no avail. It installs everything successfully EXCEPT USB MTP device which is the one I needed the most. Any solutions? Thanks!

You must be on 64 bit windows. Not even on 64bit, Still try this...
1) Uninstall LG Drivers, LG PC Suite and anything you see named LG. Restart PC.
2) Install latest LG Driver from this post (step 4)
3) Install Optional MTP Driver from this post (step 4)
4) Open Windows Device Manager (just to watch whats happening.)
5) Disconnect Internet (To avoid stupid online WDM drivers)
6) Connect phone with Usb and let drivers install automatically. Give it some time to install drivers keeping watch on Device Manager window.
7) Keep changing USB connect modes to all modes one-by-one on Phone and let drivers install.
You should see MTP drivers installed now. If this does not help, cant think of anything else. If this works, press THANKS button
EDIT: Connect USB at backside of pc, directly to USB on pc motherboard.

Ah, you're trying to use the TOT method. Some people, including me, have lots of trouble with one method but not the other. I suggest trying the KDZ method and the 10B_01 KDZ file.
Do you have the Verizon-specific LG drivers v2.20 (in the filename, not the driver version in Device Manager)? Once the drivers are installed, plug the phone in, check Device Manager and wait until all drivers are installed - all phone related devices in the manager no longer show up as no driver installed.
Then put the phone in download mode and let it install more drivers if necessary. This could take a few minutes or 10+ minutes. It usually takes quite a while for me.
After the drivers are all installed with the phone connected, reboot the computer. Even with the drivers recognizing the phone, people have found that things won't behave correctly with the LG Flash Tools until they reboot the computer after installing the drivers.

P780 8G ROW dead, only red light on charging.

My phone is on version S124. It is dead right now. Only red light shows when connected to charger and it turns of after some time.
This problem happened before also, I took it to Lenovo service center, they did something and my phone was back on. It is out of warranty, I had to pay for servicing. This has happened again, how can I fix it at my home?
I have SP flash tools, S124 ROM and Windows 7 PC.
Thanks.

Hi stympy!
I tried that exact thing at first. The problem is it does not recognize my phone on connecting via USB cable. Drivers were correctly installed as I could successfully flash firmware few days before. Now when I connect it to PC via USB cable, it does not show up in device manger, nor is it recognized by SP flash tool (stuck at Searching). Red LED turns on connecting to USB on PC/Power. I have tried all USB ports on my PC and also tried different USB cables.
I have also tried the "plug-in then reset via button on back" method. Not working.
Any idea what's going on?

Hi. Try this:
Uninstall curent drivers.
Reboot computer or laptop.
After reboot open device manager window
Look om ports area on device manager
Plug the phone now
Something with MTK69XX should appear.
If this appear you are on the good track.
If not tell me and we look for something else!

OK, tried this. When I plug in a device, like my printer, or my other android phone, Device manager window automatically refreshes device list. This does not happen when I plug-in my p780.
