MTP Device Installation Error

Hello
For the past week, I have been having a MTP driver error. I have tried using using kies but the same thing happens. I've been able to connect and install the MTP driver successfully before but now it doesn't seem to work. I looked into regedit.exe for Upperfilters but I couldn't find it. I also tried updating my Windows Media Player but it is already updated. I am currently using the GOLDENEYE 2.0 rom by iB4STiD. I have looked up everywhere and tried mostly every possible solution - if there are anymore - and still no sign of fixing this driver problem. From reinstalling windows to reinstalling drivers, still no go. I've tried USB debugging on and off but the same result for the past 10000000000times. I am willing to try new solutions if there are any. My phone is a Samsung Galaxy S4 SGH - i337. I appreciate any help that would be provided to fix this MTP driver error. Thanks

Have you tried the rear USB ports on your computer? Mine occasionally fails with both my S4 (Any rom) and my Galaxy Tab 2 if I use the front ports on the computer. Additionally, stupid question but have you tried restarting both the phone and the computer? Does it connect and work on another computer?
Also: Do you have a SD card in your phone? Sometimes if a SD card was having filesystem issues and I tried to plug it in to my PC, I would get random errors in device manager for MTP devices. Took the card out it would work. Formatted card and put back in, would work fine. (MTP service on the phone freaked out and crashed when it tried to read corrupt SD card).
I finally fix it by restoring back to factory stock http://forum.xda-developers.com/showthread.php?t=2261573 . My cables and usb ports were fine, I guess it was just a corrupted rom. Thanks anyways
thanks guys. your posts helped me to fix

[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!
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.

Sirs, I flashed the baseband (https://www.androidfilehost.com/?w=files&flid=12880) then it got working back.
solved for me
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?

Have you tried a different cord? If its not the cord the inspect the port on your phone to make sure no lint or crud is physically blocking some pins. Do you have developer options enabled? Maybe something got changed in there. Its never happened to me so these are just guesses. Maybe somebody smarter can help.

Mine gives a notification that the phone is charging when I connect to computer but if I click the notification it gives me the option to transfer files instead. You do have USB Debugging enabled on the Developers Menu, correct?
Hello guys
I have the same problem on my phone i tried everything i found on google and other forums, and the last option that i couldn't do is to send my phone to replace the usb port, but i have no warranty as i bought it already used. It's a shame that no one can find a solution here especially that the other forums at least tried to fix for some people but not here on xda which is the first in the world.

Oneplus 5 Hard Bricked

I need help with my phone as it is hard bricked. My phone doesn't react to anything except when I plug in my laptop.
So far I already tried to use multiples MSMDownloadTools, multiple times. The first time I tried I got the status-completed but my phone didn't reboot. I've tried again happening the same situation, after that, I've started to receive errno 258.
I already updated Qualcomm port, put my windows in test mode, installed OnePlus Drivers, changed ports on my pc and tried on another laptop. Right now I'm desperate... nothing seems to work and I can't get past through that error...
Any ideas on how can I recover my phone?
thanks

cannot connect to pc at all

hello I'm really hoping somebody can help me because I'm not getting answers anywhere I've halfway through a course to learn mobile tech repairs and I'm completely stuck on a Samsung SM g925a when trying to remove the FRP. I have written my class instructors and I'm not getting any response. I've downloaded all the drivers from Samsung I've updated them all but however it is not allowing me to connect the device to my PC so I can get it into odin to flash combination files. When I plug the device in to my windows 10 pc I receive a pop up saying the last USB device you connected to this computer malfunctioned and windows does not recognize it and then in device manager when I open it it shows as unknown USB device device descriptor request failed. I tried to download the drivers again reinstalled and updated them and that didn't work. I changed all my cords tried it on every Cord I had and it didn't work, yet these cords recognized other devices I had. I also uninstalled the USB driver and then I ran the hardware troubleshooter still got nothing and then I also disabled fast startup none of this has worked. I also have spent countless hours researching on line and I'm just not getting any answers and I get the same troubleshooting ideas I've already tried however I did come across a program USB debugger r but I don't know if I had just downloaded it wrong or had the wrong firmware files but it wasn't working for me I thought maybe that would help me to connect to PC. I'm still learning and only halfway through the course but it seems like this is such an easy issue that I just can't seem to figure out is there anybody out there willing to help me figure this out please I'm sure something simple Im missing or forgetting but I've been dedicated to this phone and I sure can't figure it out it's stopping me right at the gate. Thanks in advance
