[Q] Cyanogenmod 10.2 MTP Driver Problem

Whenever I plug in my phone, the computer won't recognize MTP, but it will recognize PTP. I have installed the LG Driver, but when I check the device manager it says code 28 and no driver installed. I tried to install the Google driver, but that doesn't work neither.

Tried it. Doesn't work, but thanks.

Found the solution.
1. delete every driver that's related to LGOG by going to device manager
2. install LG united driver: http://www.lg.com/us/support-mobile/lg-LS970
2. follow this thread: http://forum.xda-developers.com/showthread.php?t=2130399
3. go to device manager and search for other devices and find MTP
4. update the driver by the list of driver installed on your computer
5. find LGE Android MTP Device under portable device
6. restart your computer
This worked for me but might not work for you.

MTP device not showing

Hi, I just flashed the 4.4 official image from google. Still on stock recovery.
I do plan to install custom recovery to flash some custom rom now.
However, when I try to plug my tablet in laptop (windows 7 64bit), all i hear is that ding sound, hover over the usb devices i would see nexus 7, but it is not showing in the Windows Explorer.
PTP would show, but MTP wouldnt, with or without usb debugging enabled.
I tried to update my usb driver from google via SDK, i uninstalled first before upgrading so its a clean install, however i am still stuck here.
Any other solution?

If you have Wugfrest Root Kit, in there Click Full Driver Installation Guide - Automatic + Manual and follow his instruction.
Or you can uninstall the driver and update the driver yourself to a specific location on your computer. (this method i used) I run Win 7, and it would detect Nexus 7 but fail, when it told me to update driver i went to the folder where i put the drivers. Eventually you will find the right driver. Its a pain in butt to get the drivers to work sometimes.

MTP is not working after connecting to PC

Once I installed the USB Mass Storage enabler zip on stock Lollipop, now whatever rom I flash (be it stock or custom), MTP is not working, though the PC detects the phone when it is connected through the usb.
Please help...

Driver is not installed duly

Employ USB driver tool by googling this would resolve your agony.

Thanks for your reply, but drivers are already installed.
When I'm connecting to a different laptop running Windows 10 (where drivers are not installed), there the MTP is working normally.
But not in my laptop running Windows 7.

Uninstall the drivers on the laptop with Win 7 and reboot the laptop, thereafter reinstall the drivers using the tool stated above for MTP . Occasionally the drivers are not installed duly (i.e. Device manager may not indicate the exclamation (We may presume the drivers are appropriately loaded,when in fact the contrary usually occurs) mark or error for the driver) but the transfer of data will be precluded.
Uninstall and reinstall the drivers for Win 7 laptop for resolution.
Thank you

Filetransfer over USB does not work any more, only in recovery. Lineage 14.1

I can no longer transfer files from my phone to my computer over USB.
If I boot into recovery I can transfer files just fine and the computer recognize my phone, but in Lineage it does not work.
I choose "transfer files" in the drop down menu, nothing.
I activated ADB, did not help.
If I plug and unplug my USB I hear the USB connected sound in Windows. But there is no phone showing up and I cannot access it to transfer files.
In device manager I see the phone under USB connections, looks fine.
One thing looks faulty though.
In device manager "Portable devices"
"MTP"
It says
"Reinstall the drivers for this device. (Code 18)"
I have reinstalled drivers many times, but it always end up like that.
What to do?
It always worked fine before until I updated Lineage in June last summer, after that USB file transfer never worked unless phone was in Recovery mode.

Your best bet is to post this question within the following Official LineageOS thread for your device.

Good Luck!

This thread is not the newest, but maybe this helps anyone: I had the same thing when I flashed the wrong version of vendor/firmware for my Pocophone F1. Also Wifi wasn't working. The newest version fixed all of this.

Try this workaround:
Open the Developer Options
Tap on Default USB Configuration (or something like that)
Choose USB File Transfer
---
Whilst transferring files, don't let the screen switch off, keep it awake, i.e. with youtube.

Yeah, this is a dirty workaround, but the only alternative I've found so far is to activate the USB debugging option (developer mode) to transfer my files with the "adb push" command.

It would be really good if u upload logs, people can't read your mind, finding errors based on description is really hard.

Even if this post is old, this is my solution. I post it now because someone could need it every time in future, because wanting to re-use an old phone with lineageOS.
it's quite simple,
1) I've just search on Internet for the following words "lge android net MTP" (my phone is LG, so change the first word with your phone's brand)
2) I've downloaded the Win10 driver from LG and installed it
3) when looking at devices manager (Win+Pause shortcut), the warning device has disappear)
Hope to help somebody with that

Even now there are people trying to solve the mystery and solve the USB file transfer issue.
My solution to the problem was very simple, the second I shut off the USB debugging mode in developer tools it magically appeared on my PC.
I have the s3 mini GT-I8190N running the android 7.1.2 Pie-Nougat version

Fix USB file transfer for LineageOS 17
Go to Developer Option > Default USB Configuration > File Transfer

I flashed Lineage OS 17.1 onto an LG G5 and have the same problem.
Plug in the usb to my computer and the device does not pop up in "This PC". Windows does give the sound of something being plugged in.
Changing to usb file transfer doesn't work. Turning off usb debugging mode doesnt work.
Uninstalling the LG drivers doesnt work.

As regards the attaching of files, you have to have a minimum number of posts to be able to do that.
As regards the USB, be a little more specific like what you are trying to do, which ROM you are running, whether you are rooted, what happens when you connect the phone to PC etc which will enable the members to help you.

There could be several reasons for this, but lets start with the basics.
Have you tried a different cable?
Have you selected File Transfer (MTP) from usb options?

I get a windows sound like its connecting then in the bottom right where the time is next to that is a root sign then I get a pop up saying exactly.....The last USB device you connected to this computer malfunctioned and Windows does not recognize it. Recommendation.. Try reconnecting the device. If Windows still does not recognize it, your device may not be working properly. When I go to the Device Manager/Control Panel it doesnt do anything. I've tried to add adb to the path but maybe added it to wrong path now it won't come on. If there is a work around maybe to re-add to right path. Device Manager was fine before I added adb and added path as per internet search. Device Manager before would say something like error 39. I've tried MTP that doesn't get it to open up either.

I cant even root for the life of me now, Im on 8.0, I'm trying to just root the phone and to start the computer has to recognize it I understand but it won't, with my Oneplus 2 was fine,(I'm thinking maybe phone doesnt have the drivers built in to the file system, you know when you plug in and turn on MTP it shows the drivers app for Windows?) the only thing it errors plugging in.

On my son's pc running windows 10, I didn't have any issues connecting my OP3 to it and viewing files, nor did I have to install any drivers, same for Windows 7.
Hook phone to pc via usb cable.
Pull down notification bar and select "File Transfer" from usb options or go to Settings and search USB and select USB Preferences > File Transfer.
Browse phone from Window's file manager.
If still having issues, you can try and install Oneplus USB drivers, reboot pc and see if the phone can be recognized.

For some reason it's working now don't know what the problem was or even if it was something I did. Either way it's fixed.

If you are running Win 10, you will have to disable driver signing before the correct drivers are installed. May be that was your issue.
