No USB Functionality

I just bought my tmo s2 from craigslist and everything works fine except my computer will not pick up my phone in no other mode than just charge. I have installed all the samsung drivers (im not new to samsung i have owned many samsung phones) and also kies but when i connect my phone my computer just tells me "Unrecognized Device". I need help i dont want to be stuck on a stock phone. I dont know if flashing another rom will fix the problem with my phone. I beleive that the problem has to do with maybe a bad flash from the previous owner. Please Help!! I NEED EXPERT HELP!

Does your phone detect that it's connected to a computer? (A USB symbol should show up in your notification bar when it is)
When you plug in the phone do 2 disk drives show up in "My Computer" on your comp?

yeah if you arent getting the usb symbol like the person above me described it could possibly be a hardware problem

Someone else had this problem and I read for you to use a toothbrush and brush your charger port it worked for the other few people

No, my phone will charge but it will not detect that its connected to a computer. There's supposed to be an icon on the status bar but its not there

Use a tooth brush and scrub the USB port. Had the exact problem when I bought mine from CL
Sent from Samsung Galaxy SIV

This is a known issue with this device. I bought mine from T-Mobile and the USB went out about two months after without any rough handling or damage to the phone.
If you've double checked the drivers you have installed there are a few other options you can try.
First, try switching cables. Whether you're using the one that came with your phone, or another, just try switching them out.
Switch computers. Sometimes a different computer will cause the device to attempt to install the drivers, thereby "waking up" the USB option.
Try dialing *#7284# A menu will (should) open. Under USB there will be two choices: modem and PDA. If modem is chosen click PDA, if PDA is ticked, then tick modem and then tick PDA again. You can either hit home or back out of the menu.
You can try the toothbrush, or a can of compressed air (like what you clean your keyboard with).
Others have had success with these things, unfortunately I did not. I eventually had mine replaced under warranty. I understand you may not have that option if these fixes don't work for you. I wonder if Samsung might be able to offer you a different, or discounted, solution?
Good luck.
Also, forgot to add you can try switching back and forth between USB debugging.

I know it is not a fix, but if you learn to use ADB and use wireless ADB on your phone and an app like Android commander, you can copy files to your phone ...
Or there are Wi-Fi file apps that actually run a web server on your phone that let's you copy files ...
Might get you by until you can part with it to get it fixed ...
Or there is the 'ol get an adapter for the sd card, and copy files that way ..
Just some suggestions ...
But Yeah should have that fixed ......
Also , have you tried forcing the drivers to install on the "Unrecognized Device"? Sometimes windows gets stubborn and once unrecognized it never will be until you force the drivers ....

Cannot transfer files via usb...major pain in the butt!!

I have tried all options, to get my files to transfer using my usb cable, to my computer. I can't download a file to the device, nor can I copy/paste files to and from it, either. I have tried multiple cables, and even when it shows the phone is connected, I still cannot do a thing other than copy small files to it. This is a MAJOR problem, as I do not want to use AirDroid...it doesn't see every file I want to transfer...and something so simple as ancient usb file transfers are not working with this phone. My SGS2 worked just fine...but any help that you can give me would be appreciated. And yes, I have googled the hell out of the inquiry...just none that seem to fix my issues. :good:

what happens when "it doesnt work".
what operating system is your computer? windows I'll guess? Does it show in my computer? can you browse the files on the phone? Or do you get a message from the OS? whats the message it gives you??...
many important facts missing from your request for help....

Windows 7 64-bit...It DOES show in MY COMPUTER...yes, I CAN browse the files, yet I cannot move them, nor can I download or copy to the folders. There are also times where I get the Hardware Id Missing error, even after installing Kies or uninstalling it. Sometimes it shows up as USB Mass Storage Device in device manager, other times it shows up as Samsung I-747.

Out of curiosity, have you tried a different cable? I had a similar problem on my phone. I'd try to upload a file to the phone, even a small one, and it would go very slowly and eventually time out. I tried another usb cable and it worked fine.

Yep. Tried 3 cables total! Same result! This is definitely annoying! Thank you, though!

I think you have a legitimate phone issue sir; sounds like you're due for a replacement. The folks on Verizon are having to replace there's left and right. I think samsung let their quality control slip on this one.

Wow, really!? I was wondering what was up!!! NOTHING worked correctly, mounting wise, ever since I got it! Thank you!

Hmmm did you back up imei? If you did by going to qualcomm settings by dialing a number in your dialer you have to reenable the default for the computer to recognize your phone. That's what worked for me

Why would I ever back up my IMEI? What is the point of that? I don't recall ever using any program to do that or that did that! What number did you type? Thank you!

Because earlier lots of people lost their imei from flashing stuff. So imei backup tools were made. If you never have done that youre fine. Might be something else like reinstalling drivers

Your not using any Custom ROMS or custom kernels? I had that issue with my S3 and I was using a kernel on stock touchwiz and couldn't mount. I had to use a micro sd adapter for the computer to change softwares on my micro sd card then flash it on my phone.

[Q] How to enable USB mass storage for INTERNAL SD CARD?

I need to use Recuva on my T-Mobile S 3. I can't because it won't read it unless it has a drive letter.
Please someone create an app that will do this!
For the internal storage of course!

As far as I am aware people have been and are continuing to work on this. No ones figured out a way yet though. Only how to mount external storage has been done.
Sorry.

When I first got mine, everyone is saying USB mass storage is done for. As in it's a Samsung thing not a developers thing.

What do you mean by "it shows" You have a t-mobile SGS3 and it gives you the option for mass storage for the INTERNAL storage?
This means windows sees the device with a DRIVE LETTER assigned?

I got mine to work 1 time when I first got the phone and was able to copy all my music over, but haven't been able to duplicate success since

Can someone tell me what u mean by internal storage is it the 16 gbs that come with the phone? I connected my phone to pc and it shows the device and lets me copy my music over. Inm running windows 8 btw. However when I connect my phone with usb in my car it keeps saying unsupported anyone know how I can make my car read my music or is that related to the internal memory problem u guys are talking about

[Q] interesting usb mounting problem

so, this morning i was trying to transfer files from my computer to my phone, and the connection randomly dropped. i received a notification
that my "samsung device hardware ids" are unrecognizable or something to that effect, and then nothing would transfer to my phone in any capacity..
i continually get an error saying "cannot transfer files, the device is not responding or has been unplugged"
(added a pic of the dialog window)
i toggled the mount as camera PTP option and back to MTP, which sometimes fixes it, same problem.
i thought it may have been the ROM i was on, (i had just flashed it) so i restored a backup (2 different ones actually), same problem.
thought it was my computer (windows 7) freaking out, so i rebooted. same problem, (although after the reboot, the invalid samsung hardware ids notification stopped appearing)
updated and rolled back drivers, same problem.
resorted to kies, thinking it would update or something, no dice.
it's weird because, my computer can see all my files, and so can kies. but i can't transfer anything in or out..
i honestly have no idea how i triggered this, i was simply transferring files like i always do. (and i am using the cable the phone came with)
i don't really want to odin back to stock just yet. considering i have no means of backing up what's on my phone to my computer, and there are things on there i haven't had a chance to back up...
any advice, or ideas i haven't tried, anything at all will help.
(i also did a search for my problem and didn't find any pertinent info to this specific problem, unless i overlooked something.. in which case, i'm sorry for the duplicate question )

My first recommendation would be to reinstall the drivers from Samsung's website. Then try another computer. All else fails, ODIN back to stock and try that. If that doesnt work, take laptop into T-Mobile and show them that its not working. Might be a hardware fault

hopefully it's not a hardware problem.. but i d/led the drivers from the samsung website, rebooted both my compy and my phone, same problem.. so i guess next step is to odin back... bummer.. and i would take my computer to them to show it not working.. except my computer is a rather large desktop rig... heh.. but thank you for your reply and advice. i'll update when i odin back, i suppose..

well... i guess i figured out the problem... upon odin-ing back to stock and trying transferring stuff again, it worked...
although, i must mention that i also found that one of the files i was trying to transfer had gotten corrupted somehow.. and was causing most of the errors, (a hurt-pride way to say, the corrupted file WAS the problem)... so.. basically caused a lot of problems myself, and came to the conclusion that it was operator error. thanks for the advise i got though. sorry for the inconvenience and the time spent reading and replying

Glad you got it figured out, but just for the future try sgs3 Easy UMS. Search it here on xda. Its an app that mounts external sdcard as UMS.
Also you could try a wireless transfer program like SwiFTP. I never transfer files via usb cable anymore.

MTP bug?

Trying to pull everything off my internal SD from my t999 to place into my t999L, and if I attempt to copy more than one folder, I see a never ending "calculating time required to copy". Ive tried 2 different computers running win7 32bit. One was just recently reformatted too.... Drivers are installed because I just flashed twrp to my t999L
Running vanilla root box latest nightly

It's fussy, that's for sure. The particular driver you are using could make a difference. I don't use MTP much because it's more trouble than it's worth, but the drivers in my signature were working alright, the first link.
I just use FTP now (FTPDroidPro+FileZilla). Never any problems. The only time I would want MTP is for copying several GB of data. But since I back up often (and upload pictures to Dropbox), this situation rarely happens.

That's just it though, I'm attempting to pull about 10gb worth of data. I'll try your drivers, the 1.5 one. I will report back. those apps though, are they both for android or are they windows applications?

FTPDroidPro is the FTP server that sits on the phone. Do not remember if there is a free version, but probably, since, well.... Pro. FileZilla is the client and I think it's open source. Either way, it's free.
My router is terrible, and I can still transfer 4MB/s. With a nice router, I'm sure it's faster than USB 2.0. FTPDroidPro also has support for root access. That is incredibly useful.

The only thing I can think of is that this is either a 4.2.2 issue or related to Vanilla Rootbox exclusively. Just tried your driver and still the same issue. Guess I have no other choice is to try your app combo and see what happens. This is most frustrating, as my music and pictures are stuck on my old sgs3 and would rather not live without them

In case there isn't a free version of Aerowinders, this is what I use, and it does have a free counterpart if you just want to try it our way.

If you need any help setting up, let me know.
There's probably nothing wrong with your phone or the computer. I've had tons of issues, too. One more thing you could try would be to make sure those drivers are fully uninstalled (through device manager also), and install the old 1.4.6.0 ones. These old ones probably won't work with your LTE version, though. Just another thought. I personally think FTPing is the better solution. It's faster than digging out the cable, for me.

Never had an issue with MTP until today. Honestly I kinda grew to like it more than the old UMS method, as the phone was still usable. Just installed ftpdroid and filezilla now, trying to see if I can get this working, let alone access the internal storage.

Alright, so far, I will give this a 4 out of 5 stars. only 4 because I'm not quite familliar with the interface and it is pretty intimidating. I do however LOVE that I can simply resume the transfer process should my phone reboots, which it did, so I don't have to start all over. Pretty sexy.
If you have some kind of guide or easy way of explaining this, I'd love to see/hear it. appears it's about 2.5mb/s, which is the average speed of my data plan for my ISP, so Idk if it goes off the router or my upload/download speed limit.
@DocHoliday77, I will look into your method, but if you could explain it a bit to me that would be great. I know little to nothing about FTP.

Super simple. Make sure you're on wifi.
Open the app and start the server.
Open Explorer on your computer and in the address/path bar enter exactly what it says in the app.
Ftp://192.168.x.x:2121
Enter pw.
That's it.

You could also transfer the files to a MicroSD Card or USB Thumbdrive (via OTG) and then do the same on the new phone.

OTG is USB On-The-Go, aka USB Host mode. You can plug in USB devices into your phone and use them directly. I was suggesting to plug a a thumbdrive into your OTG cable into your phone and copy the files to it using ES File Explorer or similar.

Ah ok I think I understand. Well I tried the ftp method yesterday and pretty sure I pulled everything I needed off of it. Slowly migrating to the new device. Don't need orphan data and such.
Using mtp on the new device seems to work well, though haven't tried to pull anything off it, just push. Will test later tonight. Perhaps getting this refurb'd device was smart in the long run besides just LTE? Funny how things work...
