[Q] MTP not working after jelly bean update - T-Mobile, Samsung Galaxy SIII

Hi, So I have the sg3 T999V with Wind and I updated to jelly bean via kies today.
So I did lose root and cmw
but I used the root66 way of rooting it after the upgrade and it worked.
However, after the upgrade I encounter the MTP device not working problem.
I first unchecked usb debugging mode and it worked for a brief moment but then proceeded to not being recognized by my computer again
I have windows 7 32bit
So this is what I tried:
1) regedit described on this forum - did not work, and there was no upperfilters under EEC5AD98-8080-425f-922A-DABF3DE3F69A
2) reinstall kies,driver under my computer-manager, and kies troubleshooting - always returned with MTP not installed correctly
3) factory reset one where I signed into google account right away when prompt and another left it till later, the instance where i signed in later worked until i restored system-app data with titanium backup
4) Tried all the ports on my laptop- non of which worked
5) made sure I used the usb cable that came with the phone
So I am out of ideas and having tried most of the methods suggested on the forum I don't have a next step
the reset worked well till I backed up with titanium so perhaps it is a system setting that is preventing the mtp?
Please help I use my sg3 as a music player for my long commutes and losing the MTP function would be major. :crying:

I have this issue on and off with my S3. It tells me my Device ID is missing. What I do is the following:
1. Download the S3 Toolkit software http://forum.xda-developers.com/showthread.php?t=1746682 and extract
2. Go to the directory you put the toolkit in and look for the drivers folder. There are two (maybe 3) files there. The USB drivers, and an application. Right click on the application, and run as administrator.
3. Make sure phone is NOT plugged in
4. Look for all Samsung related files. You may have USB component, USB modem, CAC Driver, MTP Driver, ADB driver, And a T999 Driver. highlight and click the recycle bin next to teh X on the menu bar.
5. Plug phone in, and let it recognize the components again.
6. After it is complete, it may work, or you may have to plug it in one more time for it to recognize T999 or MTP again.
7. If it doesn't work, start again, sometimes it takes a few times.
I do notice that with the Universal Naked drivers I don't have any issues, but then I can't connect to Kies. Also curious to see if your Device ID is also missing, this is the first column in the application you are running. Mine are, which I think is part of the problem, but not sure why they vanished, or how to get them back.

I don't have a solution for your windoze problem
but if I understand correctly, you need to transfer files from pc to phone
you have wifi?
both pc and phone using same wifi?
on pc.. open sharing to LAN
get ES File Explorer (or similar) from the play store
in ES, switch from Local to LAN shares
tap New.. then Scan ... your pc should show
tap it and hold, edit login parameters as necessary
tada ... now you can move files from pc to sdcard or ext sd card, no prob .. Local to LAN or vice versa
tip: I opened the 5GHz band on My dual band router and have My SGS3 connect on that band ... this achieves speeds up to 150Mbps between pc and phone instead of usual max of 65Mbps on 2.4GHz band
another file transfer method ... Dropbox
drop files on pc into Dropbox, pick them up in the Dropbox app.. or vice versa
however this will use your internet .. and whatever your monthly limit is ... twice!
once to transfer from pc/phone to Dropbox server... second time back from Dropbox server to phone/pc
the first method using wifi LAN doesn't use your internet, not limit, at all

Having weird troubles trying to connect the phone by usb

I have installed and reinstalled the samsung windows drivers about four times.
My phone has not yet been activated and I'm not sure I'm going to attach it to service for the foreseeable future instead of possibly using it as an ipod touch with a keyboard.
I have connected the phone to my laptop one time. I feel asleep with the phone searching for drivers (the drivers had already been installed but the status bar message said it was searching anyway) and when I woke up it seemed fully connected. I was able to cwm3 root the phone but bricked it I think by putting an ext4 filesystem on without moving immediately to an ext4 rom.
I've restored it to stock and through wifi updated it over the air to ec05
Ever since then I have never been able to connect using any of the usb ports, trying two different usb cables, the oem and a generic micro-usb cable and using either windows vista or ubuntu on this computer.
Clockworkmod reports that the phone is not connected and I am not able to see the phone as a hard drive when I set it to mass transfer mode.
In download mode, odin is able to communicate with the phone reliably.
I've repeatedly tried all ##8778# settings and I've set debugging mode off and on. Device manager shows that the phone is connected to port COM7.
Is it possible that the activation program is preventing the USB connection? I would think not because the activation status has not changed since the one time it did connect, but I'm at a total loss for any explanation.
My next step is to try another computer but I don't have one handy.
Is it possible to root a phone only through odin, or to put a file onto the sd card that can root without the use of the computer?

Thanks. I'm on ec05 now, so I'm OK with that. I'd like to root either with or without resolving the usb connection issue.
Is that possible at all?

While it isn't JUST a root that you are doing, as stated by budderocks, you can flash the pre-rooted EC05 tar file through Odin, although it will require you to reinstall any apps you currently have. This will start you out with either a stock(ish) setup, with root already included (not sure about Clockwork though), or you can use the one modified for the ext4 filesystem with CWM 3.0.0.6 included which will convert it to ext4 the first time you boot into recovery.

I have been through this myself and came short of beating my head against a wall before reading that it "may" be a cable issue.
Well, after tyring everything else, (because it couldn't be something as simple as changing to a different cable, right??!!) I pulled out an old cable from my Blackberry days and BAM - my laptop searched for and loaded the needed drivers and sees my phone everytime I plug it in now. I have also used a cable from a friends phone (not a Blackberry) and my laptop still sees the phone so I'm not advocating for Blackberry cables specifically.
Bottom line is - the Samsung cable is a piece of crap. It may work for a day or a month, but it will soon (for 98% of Epic owners) become nothing more than a charging cable before long.
Try using a different cable (not a Samsung model ) and see if that works. If so, then ODIN/one-clicks become your best friend(s)!!
Hope this helps!

[Q] How do you transfer data from the phone to computer via USB Cable

I have no option for usb data transfer. Just MTP and PTP. When trying to drag and drop I get "Calculating the time required to copy the files". It copies nothing.
Airdroid, wifi explorer, kies doesnt transfer a damn thing.
ANY HELP IS APPRECIATED!
Make sure that your drivers have been installed properly, first off (I think this is a big problem for a lot of ppl). And on the phone, in Settings > Storage > Menu > Computer Connection > "Media device (MTP)" is checked. (I also believe unchecking "USB Debugging" in Developer options can help, too).
If your drivers are set up, you should get a prompt (assuming you're on Windows 7) to "open folder and view files" and you'll get an Explorer window. Just drag/drop files on the device.
You can also use a WiFi FTP transfer app (I wanna say AirDroid is a popular one?). Some prefer it this way.
How can you tell if the drivers have been installed properly?
I can drag and drop one file at a time but nothing more

If you plug your phone in and don't get an error. And in device manager it should show up as "Galaxy Nexus" or "Samsung Galaxy Nexus".

Sounds like a possible issue with your setup. I just recently re-installed a fresh 32bit Windows 7 install on my MacBookPro, and without any driver tweaking or anything I was able to connect and drag/drop files back and forth.
I do have issues with my desktop and plan on wiping it.

MTP can be finnicky but there's no technical reason why it can't work just fine (as I said it works perfectly for me and others here).
Have you tried something like AirDroid (linked above)? Or if you're just sitting on WiFi you can always just upload to DropBox (Google Drive) and download on the phone/PC.
airdroid hasnt worked for me. I'm not positive but I think there are certain files that won't transfer via cloud.

Should be able to transfer anything. Don't see any restrictions to it.
Is your Kies properly Installed?
Hi,
If your Samsung Kies was properly installed (means took quite time for installing Driver for Samsung devices). Your phone should be detected once connected via USB cable. Some devices may have different situations. Exp. file transfer in SamsungGalaxyTab10.1 will not display exact time for file transfer Window. Once device connected via USB cable, and Your device's Name Pops Up in your window, means it's successful. Transfer shd not be problem.
Sometimes, Phone may not the cause, perhaps ur Pc/laptop might limited capability for Kies Support.
If your case is different, perhaps you can uninstalled and reinstalled it in control panel. Uninstalling Kies will not remove ur Phone's Driver data. Hope this Helps.
Sincerely,
whitefang
**** takes forever to transfer via usb. is this a known issue on the nexus or just me? I have never had a phone with issues in transfering data. I'll give a clous service a try again. I appreciate your help

It's a known "issue" that people have really funky PC setups and have issues installing drivers. It's not inherently a technological problem with MTP or the Galaxy Nexus. As I said before, it's just a bit more finnicky than USB Mass Storage (UMS), which is used on most other phones.
I'll keep referring to the fact that on a bare Windows 7 install, with no previously installed drivers, I was able to plug in my Galaxy Nexus, auto-install drivers, and xfer files back/forth without a hiccup... that'll give you an idea for where the problem lies

Like martonikaj said, you should be able to transfer everything wirelessly. It's probably your fastest bet.
I either do that, or use ADB. While it's not as fast, I find it to be more stable than MTP (but that could be just me).
I assume download files as a zip and then open them on the pc? I assume all I would have to transfer would be titanium backup since it contains all app and system data. I know some of my questions might seem silly but i want to make sure i dont loose any data.
I've tried downloading the samsung drivers on 3 different pc with 3 different operating systems and cant get the drivers to properly load. I'm a little upset with Samsung at the moment. I never had a problem wit HTC or Moto phones.
you can use Alt Mounter app on mac & windows
go to goole & search it
then download AltMounter.apk & install it to your phone
then download altmounter for windows & install it to your pc
after that run altmounter in your pc & also run altmounter in your phone
after that plug the usb cable . the phone storage shows up in a window
this is verys simple & i like it
you can use it if you have problems with MTP
I'll give it a shot, thanks!

[GUIDE] Troubleshoot MTP Driver Installation Failed

This is a comprehensive guide for troubleshooting the 'MTP Driver Installation Failed' problem on Windows 7
specifically for the GT-I9300, but also applies to other phones (except the part about Samsung and Kies).
This guide combines all the tips and tricks found around the web that have had results in resolving this issue.
If at any point you're fed up with the problem, keep in mind that there are free apps like USB Mass Storage Enabler
that enable UMS mode on your phone instead of MTP mode.
First of all try removing the battery for 3 minutes and restarting the phone and trying then (if you haven't already).
Ok lets start.
For troubleshooting purposes,
1. Remove your Sim and Memory Card.
2. Always use the USB ports at the BACK panel of the PC
rather than the front panel and the original USB cable provided by your manufacturer.
3. Download and install the latest version of Samsung Kies
and make sure to check the 'install USB driver' at the end.
Try the following to pinpoint the source of the issue:
1. Ensure that you have USB Debugging switched off. If it is on,
switch it off, reboot your phone and try to reconnect.
2. Try a different USB port at the back panel of your PC.
3. Try a different USB cable.
4. Uninstall Kies and USB Drivers. Open up USBDeview
(in the SGS Toolkit or from the web) and uninstall all drivers that say
'Samsung' or 'GT-I9300'.
Reboot and reinstall Kies and USB Drivers and try to reconnect.
You can find USB Deview here:
http://www.majorgeeks.com/files/details/usbdeview.html
Ok so none of this worked for you. Lets try finding the source of the problem i.e. either your phone or windows.
- Make a nandroid backup of your current apps/settings. Copy this backup,
megawipe and your Nandroid backup of your STOCK ROM to an external SD card.
Boot into recovery and flash megawipe. DO NOT reboot the phone. Restore the stock
ROM from your external SD Card. Do a data wipe/factory reset, wipe cache and wipe dalvik cache. Reboot and plug in the phone to see if it works.
Megawipe can be found here:
http://forum.xda-developers.com/showthread.php?t=1832326
If it works, then it's a problem with your ROM or its settings.
If it doesn't, it's most likely a Windows issue as we've excluded everything else that it could be.
Its my phone!
- Boot into CWM and flash megawipe. Flash your preferred ROM/gapps from scratch as per the developer's
instructions. DO NOT flash backups. As soon as you're past the welcome settings pages, connect the
USB cable and see if it works.
If it doesn't then your ROM has a problem with MTP mode and you need to contact your ROM developer about it.
If it does, then it's a problem with your settings. Use the stock nandroid from here on:
Its my settings!
1. Make sure that you have USB Debugging Disabled.
2. If you use apps like Gemini App Manager or System Tuner that disable apps on certain events,
make sure you didn't disable anything related to USB connectivity.
3. Try to restore system apps like media storage or anything else that might have been
necessary for your phone to work correctly.
3. Start from scratch. Install programs and settings one by one and figure out when
it no longer connects to your pc to find the culprit.
It's Windows!
1. Download and extract the latest MTP Driver from here:
http://drivers.softpedia.com/dyn-search.php?search_term=SAMSUNG+Mobile+MTP+Device+Driver&x=0&y=0
With your phone connected, go to Control Panel>Device Manager>Portable Devices
Double click the MTP Driver and go to the Driver tab. Click 'Update Driver'. Now click
'Browse my computer for driver software'>Let me pick from a list of device drivers on my computer>Have Disk
and browse to the folder you extracted the drivers to. Hit OK>Next.
See if it installs
2. Open Start>Run>Regedit and browse to
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\
Browse to these two folders and delete the registry keys called 'UpperFilters' and 'LowerFilters':
{36FC9E60-C465-11CF-8056-444553540000}
{EEC5AD98-8080-425F-922A-DABF3DE3F69A}
Reboot your system and try to reconnect.
If the keys don't exist, create them and delete them:
-Right click>New>MultiStringValue>UpperFilters
-Double click the key and enter any random value
-Connect your phone now and let the install fail
-Disconnect the phone and delete the key you created
-Reconnect the phone
2. Uninstall Kies and drivers with USBDeview. Install the MTP Driver from here, reboot and try to reconnect:
http://www.microsoft.com/en-us/download/details.aspx?id=19153
3. Install the latest Windows Media Player from Microsoft. If you don't like it, you can always remove it when you're done. Reboot after install and connect your phone to see if it worked.
4. Try an OLDER version of the Samsung USB drivers from below. Uninstall all the current drivers with usbdeview and then install these. If you know of a date when your usb connected just fine, use a driver closer to that date:
http://drivers.softpedia.com/dyn-search.php?search_term=Samsung+USB+Driver+for+Mobile+Phones&x=0&y=0
5. MAKE SURE YOU HAVE NO VIRUSES OR TROJANS ON YOUR SYSTEM AS THIS CAN
COMPROMISE SECURITY!
Open Start>Run>cmd and type this into the command prompt:
net localgroup Administrators "local service" /add
Reboot, and reconnect your device and see if it works.
5. Do a clean install of windows, install the motherboard and video card drivers, then install Kies and USB Drivers. See if the phone connects.
If not, update using Windows update and try again. Don't install any other programs
until this step is complete.
Thats the end of the guide. If you've tried all of these steps and failed, then it's a good idea
to just give up and use one of the many alternatives.
Use UMS Enabler or simply connect your sd card to your pc directly rather than from the phone.
You can even do wireless transfers using ES-File Explorer or Samba filesharing.
Hope this helps!
None of those worked to me. i tried using drivecleanup, reinstalling wmp, installing kies, debug mode, removing upperfilters but everytime went back to the same error. What worked to me was:
- download file from that post http://forum.xda-developers.com/showpost.php?p=37042201&postcount=28;
- extract files from that package to some folder (;
- delete all wpdmtp* from \windows\system32;
- plug phone (it will give an error installing drivers);
- go to control panel -> system -> device manager;
- right click on mtp and poitn to the folder of extracted files;
after that, windows was able to install mtp properly.
Thanks to user Israelleite for the download.
Driver for Redmi note 11 MTP Failed on Windows 11 x64 = Test this _Link_DownLoad

Is there a fix for the MCP connection fail thing?

Hi,
I'm having some issues where the MTP driver fails to load. Tried all the obvious stuff and did a lot of reading of forums and stuff but can't find a fix. Could anyone help me to fix it please?
Here's what hardware I have and what I've tried so far:
Tab Pro 8.4 16gb wifi UK model, rooted.
Connected via cable to Dell XPS 17, latest USB drivers installed, win 7 x64.
First of all, I enabled USB debugging and windows installed drivers for all except MTP.
Tried installing the Samsung driver package, same problem. Uninstalled at present.
Installed kies, didn't work, wouldn't even connect to the device. Uninstalled.
Followed the instructions on the wiki but the suite software installs the driver succesfully but then windows won't accept the driver. Tried the workarounds in the wiki but still no luck.
Tried rebooting the tablet and leaving the cable connected.
Tried wiping the cache.
Tried restarting both the tablet and laptop after reinstalling software and drivers, still no luck.
Found several workarounds on my travels, one was a command line for windows to add to usergroup ( it's on the laptop downstairs, will add it to the post tomorrow).
One post said to change a registry entry...really? Tried that, and another registry trick, but still no.
Using the same laptop, I had similar problems trying to flash a custom rom onto an s4, but the CM installer worked first time. I've done a fresh install of win 7 since then.
Can anyone shed any light on this for me please? Is there any kind of workaround? Running out of ideas!
Thanks
Fixed this, well, kind of. Here's a quick rundown of what I did, for people like me who are struggling with connection problems.
I thought I had tried everything, was going to dump the whole thing and then remembered that I'd fixed some previous USB problems (sound card) by doing a clean boot.
First, remove Kies.
The only other thing that is required are the samsung mobile drivers from their website. I tried with and without and this would only work with them installed.
Restart your tablet, make sure MTP is selected.
You can find out how to do a clean boot for you version of windows here.
Leave your device connected via USB cable. Once you have clean booted into windows, windows will attempt to install the drivers from windows update, let it do this. It can take a minute or two to complete. You should then see a green tick in the notification area rather than the dreaded red cross.
If, for some reason, the driver doesn't install first time, you can unplug and then plug back in the USB cable and this should do the trick.
What I did find, is that the connection wasn't consistent, I could restart either my laptop or tablet and then it wouldn't connect, so I'd have to go through the above process again to get it to connect.
Doing this allowed me to flash the Clockworkmod recovery with odin 3.09, but for whatever reason, I was still unable to use the recommended Eimdall suite to flash cyanogenmod.
In the end, I downloaded the CM11 zip file to my tablet (via http) and then used ES file manager to move it to the SDCard root and then clockworkmod picked it up from there.
Also, once CM was installed, there were no connection problems at all, as far as I can see.
Hopefully this will help others in the same predicament.

Dead SM-605??

Hi All, sorry this is a fairly long post.
i recently "Upgraded" my SM-P605 to Android 9 and it has been working fine.
i have, however, been experiencing connectivity issue with file transfer via USB.
i have tried several cables (3 Genuine) including a brand new "Generic" cable and keep getting the "device descriptor request failed" error.
i have also tried multiple PC's, loaded all recommended Samsung drivers and finally relented and replaced the USB port in the tablet itself, which still did not fix the problem.
Convinced after all of this it must be software related, i then decided to re-install and earlier version of Android which i copied over to the Tablets internal memory.
i logged into TWRP and wiped the tablet ready to reinstall Android 7. and when i tried it says the zip file is corrupted.
i now have a tablet that wont load the zip file i have, wont read from an SD card in the tablet or OTG (via TWRP) and is unable to connect to a PC via a usb cable..
if anyone could offer any suggestions i would be extremely grateful as i dont want to "Dump" this tablet as i use it daily for work..
Why it does not read the SD card? I would expect that should work and should be the safest bet here...
-Maybe the zip file really is corrupt, which can be easily told by unpacking via pc.
-If the tablet can still charge the battery usb is most likely okay.
-Sdcards can fail by becoming read-only. Most easy to tell by unsuccessfully trying to format them in the tablet or pc , but e. g. under Windows you seemingly can successfully delete and copy stuff, everything as it should even after forced refresh via F5. But after reinserting the card or rebooting the previous state is back.
-ADB has been enabled in developer settings? Then you normally get a notification where you can modify usb mode. Charge-only won't work, but most of the rest should do (Dcim/mtp/msp...) .
-And all the time Windows has to recognize the device via PnP and auto-install drivers for the current usb mode. Besides the aforementioned storage drivers for flashing and communication a modem driver and virtual COM ports must be auto-installed.
In this department i had lots of trouble with a phone based on an old TI OMAP SoC under any Windows newer than seven. Only Download mode invoked on the phone itself was still working and only zseful to restore stock rom, while in the more flexible Fastboot mode the phone wasn't recognized by Windows.
Samsung devices seem to support Fastboot only, but call it Download mode.
To come to an end, if everything fails i'd recommend to install stock rom in "download recovery" (Fastboot?) mode via Kies. If this also fails try to put the P605 manually into Download mode (Power and Volume minus or plus), no need to press home button, as often advised. After this, work your way back to Twrp, custom rom and root.

Try connecting the tablet to a Windows 7 PC/laptop, making sure it's on an Administrator account (so it can autoload/download needed stuff). Not Windows 10 or even 8.1, but Windows 7.
I had the same problem a while back ago; if your attempt with this method succeeds then report back; I had an unconfirmed hypothesis about this issue.
