Phone not getting recognized by PC

Hey all,
Of late, whenever I try connecting my GALAXY 3 to the PC using USB, nothing happens. USB-Debugging is off. And it's supposed to ask me everytime I connect. But lately, nothing happens when I connect it. It does charge though however. And I do get the "Device Connected" sound. But that's about it.
Anybody faced a similar problem? Anybody know the solution to it? Will a reflash of the ROM do the trick? I currently use Kyrillos' ROM

I checked with another PC as well, it's not getting detected. I'm on Windows 7 Professional.

i had also faced a similar problem.
SOLUTION THAT WORKED FOR ME-go to settings -> privacy and do factory reset.
also go in recovery and there also select the third option wipe data factory reset...
after this the pc detected me...
hope this works for you..
dont forget to press the thanks button if it worked...

if you are using some 3rd party laucher........switch back to twlauncer (android launcher) and try.......

check whether you have phone drivers installed or not.....
if not install kies once...

How will I get my data back then?

Try this:
Make sure that the USB cable is not connected from phone to PC.
On the mobile, dial *#7284#
An app called 'PhoneUtil' will open up.
Under USB section, make sure that 'PDA' is selected. If its already selected, then select 'modem' and then again select 'PDA'.
Once done, press 'back' to exit the app
Now Plug the USB cable again. It should work now.

Seems a common enough problem, happened to me as well. The only way I fixed it was a factory reset (tried the phone util thing and it didn't work for me). To save your data I recommend you use a backup app such as my backup root. To do this you will need to root your phone which you can do easily with z4root which you can get here: tiny.cc/z4Root. It will only soft root your phone (temporary root only lasts till you turn your phone off) so it is easily reversable and no chance of brick.

[Q] USB device not recognized

I've flashed my i9505 many times. I can't remember exactly what I've done, but now the situation is very weird.
1. I can go into Download mode. But Odin doesn't recognise it. Kies doesn't recognise it either. The error message on the bottom right corner of the screen says "USB device not recognized. Your usb device has malfunctioned." I've tried re-install the USB driver, use the original USB cable, even tried it on another PC with no luck. I suspect the very low level USB driver in the phone has corrupted because possibly I flash something wrong in the past.
2. I can go into Recovery mode and flash new ROMs in zip format from there.
3. I can use my phone normally, e.g. make phone call, SMS, WiFi......My computer can recognize my phone as usual when I am in Android.
Any thoughts? Helps are appreciated.

Hello,
Uninstall any previous installed of Samsung USB drivers, clean your Windows registry through CCleaner (not needed but highly suggested) then download and install latest Samsung USB drivers
Now download mode will be recognized on PC
Inviato dal mio GT-I9505

There is an easier way. If you are using windows, go into control panel-> Devices-> Right Click on your phone-> there should be a Driver Details-> Go details I think it is-> Uninstall driver-> Have the box ticked-> Uninstall-> Unplug then replug the cable in and it should work.

I've tried to re-install the driver. I even tried to connect the phone to another PC where the driver had never been installed before. Nope.... it doesn't work. Actually, I've searched around in Google for long time. The most likely reason is the usb piece of Android code is corrupted. Well, maybe not android, it should be the lower layer of Linux. I previously installed dual boot system follow this link and I screw it up when I tried to upgrade the primary OS:

You said that in Android USB connection works.
The download mode depends on bootloader, that can't be touched in any way by Android, even you can't touch the bootloader.
It's also write-protected, you can only upgrade it through Odin or through an official OTA update, when flashed you can't downgrade and can't write on its partition if not through JTAG

Sorry mate, I am still stuck in Odin. Since I can flash new ROM via recovery mode and everything else still works, I give up.

Reinstall ubs host driver (Not the cellphone one)
Use another cable.
Put your Phone in MTP mode in the options above when asking just charge or transfer pictures MTP or Mass Storage.

Tap on the "Charging mode" notification when your USB is connected and you'll get a pop-up that let's you select MTP mode.
Alternatively you can go to Device Manager and look for any error icons (think they're yellow triangles - been a while since I used a PC). Right click and uninstall all the offending ones, the disconnect and reconnect your device via USB.

In a lot of MM roms, you have to go in to developer options and select MTP under 'MTP configuration' in there. Even if it's selected already, tap it again and it should pop up asking what to do when device is connected on the pc. $5 says that does the trick. Easy but surprisingly tough one. One other problem I'm running into lately with the new windows 10 is that it has driver signing enabled by default and often rejects the driver you install or just doesn't use it even if it's installed. So if the driver is the problem (or more accurately windows 10 is refusing to acknowledge the installed driver), you might need to disable driver signing enforcement. Here's a link how to do that: http://www.howtogeek.com/167723/how...8.1-so-that-you-can-install-unsigned-drivers/

I did flash stock mm and that's when this started happening, I flashed stock mm because I was having issues with turbo charge on a ROM I was using. But flashing back to stock mm didn't help and now I can't even connect my phone to my PC..

Broken digitizer Nexus 4, trying to control phone from PC

Hi there, the title explains most of it, I'm trying to control the phone with k.janku1's control tool, here : http://forum.xda-developers.com/showthread.php?t=2786395
The phone has USB debugging enabled, is in MTP mode and ADB will find the device fine when I'm in recovery but when I reboot the device ADB won't find the device when it's turned on. I don't know if I'm being stupid or not! I also have all the drivers installed etc

I can't get Vysor to detect the device, I have USB debudding enabled but I'm not able to use the device at all as the digitizer is broken

Ah, I've just read Vysor's troubleshooting guide, it says to be on PTP but I'm on MTP
Is there a known way to change to PTP from MTP with a broken digitizer? I can still see everything on the screen as it's just the digitizer thats broken so I can use recovery via using the volume buttons & power button

There is no problem with MTP, only changing the mode may help to detect some devices. If you are on Windows I strongly suggest you to download latest USB drivers. Eventually check your setup with another android phone.

What about drivers? Trying new cable? If you flashed some ROM, kernel could be bugged - not allowing connection with PC. In your case I would reflash stock newest ROM. In my case the newest ROM (8.1) is good for me. Everything works good and connecting to PC too.

Did you install drivers for your phone? As far as I know, it must be done for every connected phone manually. What do you see in device manager when you connect your phone while it's on and in fastboot mode?
