Hi . My LG L70 D325 is working fine on it's official factory rom(KitKat) and it's on. but i have DBI Fatal Err problem so no download mode and i can't flash factory rom .
but when i connect it to any computer with windows 7 or windows 10 in MTP mode or other modes nothing appears in device manager or windows explorer .it just charge the phone. even when i turn of device and press volume up and connect it to computer i see fatal err but no drive show in explorer to fix it.. i have installed LG Mobile Drivers and LG PC Suite.
i enabled developer option but still not working.
i used to connect it to computer and it worked but recently it's not .
i tried many different usb cables . cables that work for other phones but not on my phone.
i tried it on two different laptops. on windows 7 and 10 and ubuntu.

Odd that it was fine previously but not now. Something obviously has changed. Could possibly be some random update to either your LG or your PC created some kind of USB glitch. That's in a way something out of your control so looking at what is, have you tried a different USB cable? If your PC has version 2.x and 3.x USB ports, have you tried using a different port? If you're plugging your LG into a USB hub, try plugging it directly into a USB port instead. And this is a bit of long shot but if you have other external USB devices plugged in try temporarily removing them (well, not your mouse or keyboard) just in case there's some kind of weird device driver conflict.
A more obvious suggestion, in case you haven't already, is of course be sure to restart both your PC and your LG.

Phone is not rooted right now.
and it doesn't have custom recovery.
yes i tried many different cables that works fine on other phones.
 
Ok because you can't flash a custom rom without root which is what you stated when you say "flash a rom". You can try and flash a firmware update which is in a way a factory rom, but that's correct terminology.

Have you tried @svim 's suggestions?

i tried deleting drivers. i tried my friend's laptop . i installed windows7 . tried on windows 7 and 10. even installed ubuntu and tried on it !. i downloaded all necessary files ,programs and drivers. LG Flash tools , LG Mobile Driver ,LG PC Suite.
i flash factory rom many times in past. i completely know the process. but now phone not appearing on pc to do that
 
it could also be that your phone is just really old now and all support for it has stopped. other than that i don't know what else you can do other than to do a factory reset.

factory reset working fine and i did it many times.

thanks for your respond.take care.
 
Keep in mind that a Factory Reset and flashing firmware are software-only solutions, they cannot solve hardware-based problems. Also stop wasting time trying different drivers and other such utilities, that's all software. And given you've tried different computers that are running completely different operating systems that's a dead end too. At this point, there's most likely to be some kind of USB-hardware related problem with your phone. Again, software can't fix that.

It's an eight year old phone, really dated as far as smartphones in general so it is not too surprising if some internal component does fail. Although it could be something as simple as cleaning the metal contacts inside the USB port. There are two dedicated solely for data transfer and two dedicated solely for power transfer. In your instance perhaps one or both of the metal contacts for data have just built up some grimy corrosion over the years.

But a phone this old isn't going to remain functional forever so work on this as challenging project but don't get too fixated.
