Hi happened to me too.
Type *#7284#, so you'll enter PhoneUtil and be sure both the "UART" and the "USB" are set on PDA!

Help!
I rooted my Galaxy 3 and since then i can only connect and transfer data between my phone and my computer by allowing USB debug mode. It used to work without a driver installed on my pc (only data transfer mode like with a pendrive), but now my laptop (which doesn't have Kies on it) doesn't recognize it. I tried it with my TV and it said "unsupported USB device". It used to work as a pendrive but now nothing recognizes it:---( Please help:-C

Hi to all!
I have a similar problem pls help. I haven't had this before. When I connect to the computer (USB) the phone screen is just blinking with a message INITIALIZATION, and can't connect. Not even in developer mode. And I also tried this *#7284#. Still the same not working. I'll appreciate your help.

Neo
Hi! There is no notification bar on the phone screen, because it's blinking. Or you mean this notification should be on the computer?
Thank you in advance!

What he is trying to say, is wich is the default action when you connect the USB.
Example: every time that you connect the USB the phone gets into Kies mode, or Mass Storage.
My G3 is configured to ask what to do...

Hello,im having updating problems..!

<PLEASE READ WELL>
So,i have a galaxy s GT-i9000T and it seems there is no way of updating it! i can only put it on download mode trough ADB(dont know if that has to do with anything,just pointing it out since a lot of people cant use 3 button combo) and ive installed samsung drivers,kies,android sdk,java sdk and when i connect the phone to my pc in download mode it displays ''unrecognized device'' odin doesnt detect it and kies gets stuck at 0% while in download mode im supposing neither of my <<two different computers with 3 usb ports each>> seem to recognize it im on echlair 2.1 update 1 and i am very frustrated.
any help is apreciated!
PS:sorry for long post!1!!!

Check your drivers mate.
Sounds like a driver issue. Unless your phone's USB port or something is broken.

uninstalled kies and installed HTC and samsung driver for mobile phones and still no luck,i can transfer data/files from my phone to my computer so i dont think the usb is the problem :/

Have you tried manually installing drivers in device manager?

First try a normal installation of this package:
http://forum.xda-developers.com/showthread.php?t=728929
(pick the one for your OS, 32bit or 64bit - I don't know which one you got )
If that fails too, go into device manager, find the "unrecognized device", right click on it and click "Update driver software.." or something like that.
Then choose that you have driver files for this device and point to the folder where you extracted the package and let it search for the proper file.

i already had it installed...no luck! FML ):

Well, I don't know..
Can't think of anything else without actually seeing what's going on..
Maybe I could try helping you using some remote administration software, like teamviewer, but that requires that you trust me so.. ehh.
I also read on another topic that this could also be some usb malfunction (hardware issue).
Plus you said you used 2 PC's and many USB ports so.. don't know.

odin recognizes my phone while on with usb debugging on...

so it has to be drivers issue.
but I can't really help without seeing.
try playing around with the manual way again, pick some other options etc.
i'm off to bed. good luck

Is this when in "download mode"?

this happened to me before. Go and buy a new charger and see if that works. Also have all of your apps closed maybe that will work

In the diagnostics mode that opens up, enter *#7284# in the phone dialer.

I changed and tried 3 of them but it didnt work.

PC cant recognize
I have been struggling with this issue as well.
Simple solution i found (and after reading about million posts on web as well)... ORIGINAL CABLE seems to solve the issue. I saw it posted even on one Korean forum. Seems simple enough, use original data cable that came with phone and that seems to be it. wierd

Totally agreeing with PP
PP is correct in suggesting the original data cable being used.
I had the same issue, the pc would not recognize the phone. The fix for me was to connect to the usb ports on the back of my pc. They were the only ones that let the phone connect to zune.

Btw, for these issues with USB only working on the back of the comp the culprit is either the motherboard (drivers or other) or the PSU (not enough power).

Enderpsp could be right.... Mine was the USB port, I had to plug it in a different port and it started working... Just keep trying, make sure you don't have any USB options about power management in your computer's bios

[Q] Help needed!

Ok so here's the thing. This morning when I woke up I dropped my phone on the floor and the battery flew out.Initially I thought it was nothing but later it started rebooting without any good reason. I tried restarting, it would stay on for a bit then it would go down again. I am(was) running CyanogenMod 7 on a Samsung Galaxy SI. I want to reflash it with Odin as it won't start anymore.At first it would just boot loop but now it won't even get past the first logo. The tricky part is that my PC won't recognize it , all I get is Unknown Device code 43 yada yada BS! I tried alot of drivers, I tried the have disk method with the usb driver from SDK Tools , nothing worked ! Please, give me some suggestions about what I should try more because honestly this is beyond my expertise in this domain.

code 43, has more to do with Hardware, its about your cable and PC ...so check cable, try switch to another USB port
Microsoft engineers answer
I suggest that you connect the Controller to a different USB port and check if you have the same issue.
If this does not work, you can try to uninstall and reinstall the USB controller.
To remove and reinstall all USB controllers, follow these steps:
1. Click Start, type Device manager and open device manager.
2. Right-click every device under the Universal Serial Bus controllers node, and then click Uninstall to remove them one at a time.
3. Restart the computer, and then reinstall the USB controllers.
Disable and enable the USB device:
1. Click on start and type devmgmt.msc.
2. Right click on the caution sign on the USB.
3. Select disable and reboot the computer.
4. Enable the device after reboot.
Also make sure that you download and install the latest version of Software for this. Here is a link you can follow to download the Software:

try and borrow another original samsung USB cable to test first, this is a major culprit, as numerous people including myself have experienced
what happens is one of the pins on the micro usb plug of rolls in and gets broken , also check your USB slot a good cleaning with a brush and alcohol would be good fro the connection ( do it when you have removed battery)

Got another USB cable still nothing... It's very weird, it's like nothing I heard off or read on the forums... Is there any method of connecting to the mobile using SDK manager ? I'm not really familiar to working with the SDK manager.

was your cable an original samsung cable, IF not, many common cable do not work, due to pin configurations
For ADB, you still need connection with USB cable

Here's another thing I could try. If I go to Device Manager - Right Click on Unknown Device - Update Driver Software - Browse I can choose from a list of Samsung Drivers... The question is , which one do I have to choose for my Galaxy S ? Maybe it will work like this

that was the solution given in my first post, have you not tried them all yet? samsung drivers were also attached on it and what PC software do you use XP or ?

In that link it requires your phone to be working and able to go in USB mass storage mode or debugging mode ... My phone can only stay in download mode . I use windows 7 x64 version .

I think you have misunderstood it, there are many solutions mentioned there in, cause I am the one who wrote it ..your option was to try them all to see which one solved it
for win 7 . download this driver http://www.4shared.com/zip/0LQRmsMm/usb_driver.html and give it a go, if the other failed

Tried everything from your guide...even from the microsoft sites...Still can't get my device to be recognized...If I use the Usb driver you sent it won't let me use them even if I manually choose it for my device. Don't really know what to do more honestly other than throw it away and get another phone

http://cagnazzo.name/drupal/vista_corrupted_driverstore
Try the above, then install the Samsung drivers and then connect your device.

problem is, its not the phone but its either, the micro USB slot or cable or your PC, if you have another USB cable and a lap top or a friends PC might be able to resolve your problem

[HELP] USB not working

Hi, I am posting here because I'm having a very annoying issue with my Galaxy S4
When trying to connect it to the PC via USB, nothing happens, it does start charging, but I can't transfer files (or flash through Odin for example)
It did work untill 2 days ago, I rooted it, it kept working, then it suddenly stopped
I have now tried many solutions, wich are:
Hard Reset in both ways
Reinstalling Drivers on PC
Trying different USB ports
Trying different PC's
Trying different cables
Wiping and reinstalling ALL USB Drivers on PC
Formatting my PC (Windows 7 x64)
USB Debugging both activated and deactivated
I have also tried to access *#7284#, but the "Qualcomm USB Setting" option is missing, could that be the issue?
If so, how can I restore it?
(I have tried changing it to Official status while keeping the root to update it to the last version, but it was already at the last version)
My device is currently Rooted
Device info:
Model number: GT-I9505
Android version: 4.2.2
Baseband version: I9505XXUAMDM
Kernel version: 3.4.0-431985
se:[email protected] #1
Build number: JDQ39.I9505XXUAMDE
Status: Custom
Please help me, I'm truly desperate

I think the easiest option is to try another PC just to eliminate the PC. I know you have done the format/reinstall but it's worth eliminating it.
I've had a right headache trying to update the firmware on mine and while my W8 laptop won't do it (Kies won't even show current firmware), my work W7 got a step further but still did not do it. It was only once I got into work did it work.
It could be something as sinister as the Windows firewall blocking it so check this - W7 will automatically enable it ...if you have another one installed on top, it could be that blocking it

Dude, this will sound stupid but I am on XP and my S4 connected fine with a friends Windows 7 box but my PC did exactly what you are saying.
I searched and tried installing Kies and USB drivers etc ... but nothing worked.
After hours of searching the internet I found the answer here on XDA (as always)
The answer which worked for me was......
HERE's THE SOLUTION:
1. Go to the Registry Editor (Start --> Run --> "regedit" --> [ENTER])
2. Search the following key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\
3. If you click one of the few subkeys in class (e.g. {4D36E965-E325-11CE-BFC1-08002BE10318}) you'll find the string value (Standard) on the right side with a value (e.g. DVD/CD-ROM-Drives)
4. You have to find the value "Portable Devices" on the string value (Standard) (In my case {EEC5AD98-8080-425f-922A-DABF3DE3F69A}, but I don't know if they are called always the same.
5. Once found, you see a string value called UpperFilters --> DELETE IT!
6. Finished! Now your Samsung Mobile MTP Device should be recognized and even installed correctly right away. (The name of the device changed to GT-I9100 (Devicemanager) in my case...)

Damn. sorry. guess its XP only.
Ok.. Have you got Allow USB debugging set on in Developer options?
Activate Developer options:
Open Settings on your Android phone or tablet.
Scroll down to About and tap it.
Now tap Build number seven times.
After tapping the Build Number 7 times, you will see a message “You are now a developer!” If you have a Galaxy S4 or any other Samsung Galaxy device with Android 4.2, the message reads as follows- “Developer mode has been enabled”.
Return to the main Settings menu and now you’ll be able to see Developer Options.

if so ... try this: (posted by rohan999)
So here is the cure. First connect your phone to your pc. Now right click my computer and select manage. Go to device manager and expand the universal serial bus controllers tab. Now you should see something like unknown device with a yellow exclamation mark. Right click it and select uninstall. Now reconnect your phone and try it.
Now again check in device manager after installation. It should look like the one in the attachment.
