[Q] USB Problems

I am running CM7 and just recently started having some USB problems. I plug in my USB and shows connected in the notification bar but when I click the notification to enable USB mass storage, the mass storage screen pops up for a moment and the disappears.
I have tried wiping data, using different USB cords and everything but no luck. Today I went to odin back to stock to fix but odin couldn't find my epic at all. The phone runs fine except for that. What is wrong? How could I fix it?

Did you try checking (turning on) USB debugging?
This Epic post as brought to you via Tapatalk

Just tried it with and without. Neither worked.

Anything else possible?

Uninstall ur drivers and reinstall them. Also u may have to do a factory reset. But try the drivers first.

The drivers you are given for odin? Or something else?

No...www.samsung.com/support. Click on sprint, then d700, then software, and all the way to the right is a little file folder...click on it...that will download the drivers.

Ya. I tried that and it didn't work. By factory reset do you mean flash back to stock? I could get odin to work either and I'm on MTD.
Its weird because at times it seems like its the software when at other times it seems like its the hardware. I'm pretty sure its the phone side but I could be wrong. It still charges fine through USB.

ohhh...your on MTD... i'm seeing that, that is such a headache to deal with. well i have no knowledge of that yet, sorry.

[Q] SAMSUNG Mobile MTP Device: Failed!!

My Samsung Galaxy S2X was working fine after the ICS update, but since two days I,m unable to connect the phone to my laptop. It tries to install the software automatically and after a while it give out an error saying that Samsung Mobile MTP Device failed. Earlier, the phone directly gave the option in the notification bar to connect as an USB storage but now it shows up Connected as a Media device.
I've tried every option available, from deleting files with 16 characters to re-installing Kies and the USB drivers. I tried connecting the phone to different computers but the problem still persists.
Another issue after the update was that the Bluetooth transfer rate is very slow with ~30kbps transfer rate which earlier in GB was 3Mbps+.
I'm wondering if its got something to do with the new ICS update or am I the only one with this issue? The device is on stock ICS and is not rooted.
Thanks for any HELP...
EDIT:
Solved the problem by doing a factory reset.

Download the drivers from official Samsung website. The phone is SGH-T989

@alphadog32
No luck with installing the drivers. I've re-installed the drives available on Samsung's website.

Delete ALL the drivers for Samsung phones. And re-install them. But delete them ALL

Same God damn problem for me (what the hell.... ???) currently uninstalling Kies and Samsung drivers, downloaded the one on samsung webpage, will give update after re install
Update -*> Uninstalled everything, re installed still didnt work, updated Kies, still didnt work
I tryed the debug USB mode still didnt work
i Tryed differents usb cables
Tryed Differents usb connections
Still doesnt work !!
I dont know if theres any issues with the fact that I have a non-legit Windows 7 tho...
If anyone else got any ideas please share

Uninstalled the divers, deleted registry entries and re installed the drivers.Hate to say that it still won't work.

Which system? Windows or android? and what do you mean by "restoring"? Factory settings?
I have been having the same problem for 2 months now. I don't know what's wrong. I have tried EVERYTHING! Nothing works!
I even installed the drivers while the phone is turned off, turned on with debug mode and when battery is taken off while connected: the OMAP4430 drivers: and still it didn't work, lol. I don't know what the hell is wrong with that f***er, lol? It won't give in!
I removed all Kies with all drivers many times, like 6 or 7 times, connected the phone to pc while it's off then turned the pc on, changed cable, usb port, tried different computers, tried this *#7284# thing, etc... The only thing i didn't try is black magic and voodoo! Or maybe i should try hypnosis? Or electric DC shock?
Anyway, if you have found a solution, please let me know

Wow...2 months is quite some time. Please do a factory reset on your Android by going to settings-> backup and reset-> factory data reset.
Your phone should reset back to factory settings and you're good to go.

PC data transfer issues

I have upgraded to an S3 from having a Vibrant for years. I rooted and flashed several OS's to my Vibrant in those years without an issue ever. I have been trying to get files transferred to my S3 from my computer for 2 weeks now. The computer has the drivers installed correctly. It is recognized by name when I plug it in (it comes up as SGH-T999, Kies will recognize it too). whenever i try to transfer ANYTHING it stops in the middle of the transfer. just sits there with no further progress to be achieved. This is insanely frustrating. I am unable to root this thing because of the inability to actually transfer.
Things I have tried:
Uninstalling/reinstalling Kies multiple times
Uninstalling all USB device drivers multiple times
Reinstalling drivers through Kies and through Samsung's website multiple times
Factory reset on the phone multiple times (****ing aggravating btw)
Using my old Vibrant cable
Changing between MTP and camera mode... several times
Yelling at it
I have been trying to research how to fix this garbage for weeks now. there is no concrete way to remedy this problem that i have found. every thread about this is littered with the usual "uninstall your driver and reinstall it" nonsense that is the most generic response to anything tech related ever.
What I can tell you is that my phone is definitely getting recognized by anything that can do so. Odin, Kies, My computer, etc etc... it appears that the issue lies in the actual data transfer. As I mentioned, transfers initiate but will lock up mid-process and just hang there infinitely. Same goes with Odin when I try to get it to flash into CWM recovery.
Please, help. any time spent trying to fix this issue is greatly appreciated.

Are you uding the usb cable thst came with the phone?
Have you tried different cables? Or on another computer?
Im guessing your not rooted then?
Try installing the drivers ONLY. get them here:
http://forum.xda-developers.com/showthread.php?t=1728605
Uninstall previous versions of everything first.
What version odin are you using? Use 3.07 from above post if you're not already.
Also try this app
http://forum.xda-developers.com/showthread.php?t=1711009
If you are rooted try SwiFTP or another wireless transfer app.
Sorry to mention drivers again but if you're relying on kies to do that for you it could be the issue.

Since you've tried everything else might as well follow this guide and install the drivers through the toolkit.
http://forum.xda-developers.com/showthread.php?p=28175575
I'd also run windows update and check if there's a new bios/drivers for your mobo and usb controller.
If you plug another "foreign" usb device does it install fine?

May not have any bearing whatsoever here but do you have usb debugging checked? And I think I mentioned it in the other post but try a different computer if possible.
You said that this happens when using odin too? As in you start the flash with Odin but it doesn't complete? Or it wont even start? Does it give you any message?
When plugged in in download mode, does Odin show your COM port in the upper left?
Plug in the phone and open device manager. Does it show any errors or anything?

I recommend an app called airdroid. I had issues transferring stuff to and from my Mac and haven't had any problems since I started using the program. Besides it's wireless so I don't have to worry about the wires being a problem

everything else works fine from my 6 USB ports (2 USB 3.0 ports as well). The tool kit solution still needs Odin to root. The problem is not detecting the device. it is the transferring of data. Data transfers begin but that's about it. Odin gets to "firmware update start" and then "boot.img" and just hangs there forever. no change. nothing else.
Is there a wireless way to do this? I have purchased Rom Manager but since i can't achieve root it is just useless now. The phone is brand new from the Tmobile store. Not once has it been dropped (to put into perspective how careful i am with my devices, I managed to drop my Vibrant once in ~3 years, which caused no damage, what a great phone that was). I have not been able to read about this same issue anywhere else either...generally its an issue with the PC not recognizing the device but when someone gets it to link up correctly, it works. this is the opposite.
thank you for your ideas so far.

Odin shows the "0:COM" like it should, which means it is able to read that the device is there, it just is unable to do anything after "boot.img", everything that is needed for this to work via the toolkit method is checked (USB debug and unknown sources).

I just got the s3 and had transfer issues too. Turns out my s2 drivers wasn't perfect for it even though it recognizes the device. I used the s3 drivers instead and that helped things a bit with accessing my phone's storage. So i ended up formatting my internal storage and that seems to do the trick for me.
If that doesn't work and odin still gets stuck then try different usb ports also try different wires

Try connecting without the external sdcard in.
What build are you currently on. Since you haven't roited or anything im assuming you're still on either UVALEM or UVALG1. If so try initiating the software update. It should download the ota thatll take you up to UVALH2. Maybe that'll help.

Did you do that through terminal? doesn't the single partition mean that it would wipe everything?

Make sure the drivers you are using are the same ones that are in my comment (version).
What are you trying to flash through Odin? If the permissions of the files inside the tar file are not correct, the transfer will hang, and do nothing but give a timeout message after a couple minutes. I learned this the hard way.
In summary:
Use a different USB cable.
Download drivers, Odin, and CWM from my signature. After uninstalling the old drivers manually through devman (be sure to delete them during uninstall), reinstall them from the package you downloaded. Then use Odin to flash CWM. All three of these packages are tested and known to be 100% working. Please don't ignore this step. If I can't verify the validity of your installation sources, I can't rule this out for troubleshooting purposes.
If this doesn't work, it is most likely your computer. Are there any BIOS firmware updates that improve USB compatibility, or USB controller driver updates? The USB 3.0 isn't natively supported on =< Win7, so those are third party drivers. But I will assume you are connected to a USB 2.0 port.

None of that worked. I did find a BIOS upgrade for my mobo that i didnt know was released, flashed it, and transfers still hang. i tried everything from your sig to no avail. i DON'T have access to another computer... BUT i do have Ubutnu running on my comp in conjunction with Win 7 Ultimate 64. can't seem to find too much on non-international S3 stuff for linux.
this has consumed my entire day and i am so frustrated.

Try in safe mode? This sounds really frustrating. I gave up when this happened with my mac. I think someone said it already but I always recommend Airdroid. It's just simpler.

so let me get this straight... you plugged the phone in, right clicked on it in a browser window, clicked on format, selected yes to the "hey, this is going to erase everything on the device" warning pop up, and you were able to transfer files no problem after that? no adverse side effects came from this? it sounds like it would brick the phone...

make sure you're using the factory cable for the device.
try another USB port, preferably a port directly connected to the computers motherboard.
delete the current USB drivers for your phone on the computer. reboot it. in task manager, stop any kies background processes. reinstall drivers. reboot and see if that takes.

Did you make a nandroid of the previous rom ? Flash back to that . Flashing any rom made for the NA version of the Galaxy s3 will NOT brick your phone. NO physical damage will happen in any way.
Yes check the cord to make sure its not that....samsung phones are picky....even with the same cord.
Fast charge is usually in the kernel settings menu. It will be something you would had to enable, I've never seen it come enabled on a rom. What kernel are you on ? I don't think you see that setting on TW based rom's anyway ( I assume you are on SoA right now?)
Have you tried to do a complete wipe and flash another rom ?

I restored the Sons of Android ROM (nandroid) that was still on my external SD card and that didnt fix it.
I just did a complete wipe (Cache, Davlik Cache, System, Factory Reset, and Internal Memory), then installed the Wicked ROM with the stock kernel. It still doesnt work.

I used Mobile Odin to flash back completely to stock, and the usb still would not connect. I do not know what else to do. I will have to remove the SD Card and use a card reader for now. I can flash back to stock when if I want to take it in and get it fixed or replaced.

did u already try another cable, I had over 5 cables that suddenly stopped working for no reason, only charges but it doesn't connect to the pc..
so try another cable is my suggestion.

[Q] UPDATED**** (SOLVED)No Data...and no USB to PC...now what? :(

UPDATED**** 1-23-2014
The USB issue was due to the port malfunctioning. I ordered a replacement part via Ebay for about 7 bucks and fixed it. Now I have PC access. As far as in updating the firmware...after 12 failed attempts via AT&T I just manually did it via Odin and now it is updated. Thanks for everyone trying to help me out. Hated it was a hardware issue and not just a tech/Soft problem :/
The past week I have noticed my Note 2 charging slower than normal. Sometimes randomly disconnecting and connecting when plugged into the ac adaptor. I figured it could have been the cable or the adaptor itself...so I replaced it. It seemed to work...but then it was acting buggy again. Then...lastnight I noticed when I was wanting to transfer a few file from my laptop to the phone...it would charge the phone but would not allow it to connect to the file system at all. I scoured the net for solutions and tried just about everything I could find...as well as the more simpler options as try a different cable...but nothing worked. I also tried it on 2 other laptops...no luck.
My phone was rooted...but never used a custom rom and so I decided to just unroot and do a clean slate in case there was something that borked. Everything went smooth...but now, after doing the unroot and factory reset...the usb still charges...but no connection at all. I went through all the settings and set them as they should and nada. On top of that while I do have my phone service...I have no data at all. I have called att and they were no help. Samsung passed me off to android customer service and they were no help. So now what can I do?
Problems:
-No mobile data available
-No USB to PC file transfer ability (kies air works...but not usb to pc)
-I also cannot update past 4.1.1. The updater says I can check again in 24 hours....lol

Ok...so I fixed one issue already. Found a solution to the mobile data network issue. It would appear that due to the factory reset...it lost all of the APN info for linking with at&t. I found how to restore it here: http://forums.att.com/t5/Android-Di...-Phone-APN-Settings/td-p/3467513#.Ustjil8e-Co

To fix the USB connection to your computer
You need to connect USB. Then, in dialer, dial *#7284#
Go to Qualcomm settings
Select MTP+ADB
Done."

Tried that...before I unrooted and even after unrooting. Still doesn't work

Try installing Samsung Kies on your computer and updating your drivers.
Or try a different cord it might be a bad cord.

Have you tried putting the phone into download mode amd see if it will read your phone that way?

Didn't think about trying that. I just attempted though and no luck either
This is irritating because ever since I unrooted and restored to original fw the usb charge works perfectly fine...no longer cutting in and out like it used too. But just cannot connect to the PC via USB for file transfers. Kies works fine doing that...but USB is no long an option

Have you tried uninstalling the old USB drivers for it then reinstalling them?

Yes...no luck

So I did a factory reset again just in case...still the same issues. USB will charge...but no connect. Kies and PC will not see it. Only kies air works. On top of that I have now attempted to update the firmware via at&t through settings and it fails EVERY time. It downloads 100% and after reboot and goes into at&t installation it always fails at 24 or 25%. 5 times in a row...for 5 days is ridiculous. Any more ideas?
At this stage I wish I could re-root it and then flash the original stock rom again to make sure that it didn't bork the first time. But I cant I'm assuming because I need to be able to connect via USB. Am I wrong? Am I wasting my time?

Since USB is charging. Can you check under device manager, what name it is showing for your device? May be you are missing drivers therefore your phone is not recognized by PC.

It doesn't show anything. The only thing that stops the phone charging when I disable or uninstall is what is labeled Renesas electronics USB 3.o root hub and host controller. 2 separate items. BUT...its not plugged into a 3.0 port anyway...even though in the past it has worked fine...for over a year no less. I have uninstalled that item...as well as uninstall the Samsung drivers before...rebooted while phone is NOT plugged in...re-installed the Samsung drivers...then plugged the phone back in and it still doesn't work. Still charges...and the item comes back...but no usb to pc file exploring capabilities. Same for other computers too. Have tried another computer as well...one that my phone has never plugged into. It charges...but no connectivity. The computers just don't even see it for some reason.

Is there a way I can root the phone without USB to pc support? I'm hoping to try and update it once rooted with ODIN.

You don't need root access to flash a stock rom. I was having usb-charging issues, and a return to stock 4.1.1 cured the issue. I replaced the USB board but that didn't fix it. So, stock would be my advice.
You could put the stock package on your SD card using an adaptor and your PC. But I don't know if you have a custom recovery.

My only thing is I have no usb to pc file sharing capabilities unless I use Kies Air. Otherwise I cannot. I have tried now 8 times so far to update the phone and I cannot. It downloads fine...but upon rebooting to install it fails everytime at 24 to 25%. All I want to do is update the phone. It is a simple as that.

Take your SD card out of your phone.
Put it in an adapter.
Put that in a PC with an SD card slot.
Copy the stock ROM to the SD card.
Remove the SD card from the PC and adaptor, then insert it in your phone.
Boot into recovery and flash the ROM.

When you say boot into recovery...are you talking about where I load rom from sd card...adb or something like that? And...can I do this for 4.3? I have 4.1.1 already. I was trying to update to 4.1.2 to see if it will fix the usb issue as well as the updating issue. But if I just had the 4.1.2 and flashed it would that do the same thing as updating?
