Bro's I have a galaxy s3 32gb gt i9300 with stock 4.1.2. When I connect the phone to my laptop via usb (laptop is also Samsung) I hear a beep sound on the cellphone and it begins to charge. However, I see no options and no usb connected 3 pin symbol in the panel of phone and nor is there any other option like mount cellphone etc. I do have latest version of Kies installed on my laptop but even that shows no device connected. Please help guys I have spent a bunch of hrs trying to figure out how to get it going but eventually had to register on this forum for help :silly:
Tried a different cable? Usb uses fewer pins to charge than to connect to a pc. Perhaps the cable is damaged (or usb socket).

Much thanks for the quick reply.... No I don't think the port or the usb is damaged. Further, I'm using the stock usb cable provided with the phone. Any other suggestions?

And yes tried different usb cable, plugged it to different pc's, manually downloaded drivers from Samsung but still the dawn thing doesn't work
Edit: just now tried connecting a different cellphone using s3's usb cable on the same usb port and that works fine. So I guess that confirms both the cable and the port are fine
By port, I meant the one on your s3...
Check its clear. If it is, factory reset. If its still a problem, send for repair

I'm sorry for my quick scan on the thread if I miss something.
Maybe you should try go into recovery and mount USB in there to see what happens or try download mode as well (in this case, with download mode you can see whether USB works or not, if it works then means maybe problem with ROM, so you don't have to send to repair because software issue is not really a issue here, and if it doesn't, then download flash won't start so won't affect on your warranty for flash counts )

I had this problem before with a new brand cable, i just solved the problem buyin a usn charger for Cielo cards.
amazing.
Solved
I tried everything possible....
uninstall drivers. reboot laptop. install drivers. reboot laptop. plug in phone. no sucess.
put phone in download mode and plugged in. no success.
tried on different laptop running Windows 8 and Windows XP. Still no success.
Then i read about this somewhere...
said uninstall drivers. reboot laptop. install drivers. reboot. make sure USB debugging is OFF. Plug in phone. Switch ON USB debugging. Laptop should now detect the phone. But that didnt happen either. No success again.
Also read....
Go to phone dialer.... dial *#7284# to access PhoneUtil > "Qualcomm USB Settings" > set it to "MTP + ADB" .... phone will reboot. Then connect via USB and everything will be ok.
Unfortunately....
dialing *#7284# to access PhoneUtil did not show me Qualcomm USB setting.
It gave me 2 options:
UART> Modem or PDA (here Modem was selected for me by default)
and
USB> Modem or PDA (here Modem was selected for me by default)
I left UART as Modem itself.... but changed USB to PDA. Then click "SAVE and RESET" button.
My phone then rebooted. Once my phone rebooted and i was on lock screen/home screen.... i connected the USB to my phone and voila... my laptop detected my phone as GT-i9300 and show both my SDcard and extCard :good:
Give it a shot and lemme know....
I have same problem. I tried 3 diferent usb cables, two original, 3 computers and nothing. I used MTP few days ago and now nothing in options, just cahrge. I tried factory reset, clean cache, usb debuging on/of, in download mode too... Reinstaled Kies and drivers. I cleaned usb but still nothing. I tried secret code but not have option ADB+MTP. Any help? Sory for my english

Does #*7284# give you the following:
------—-—-------------
UART
-Modem <--- selected by default
-PDA
USB
-modem
-PDA <--- selected by default
???
If under USB, modem is selected by default, then change and select PDA.
Leave UART value to remain as modem itself. No charge here
Or worse comes to worse...
While keeping phone connected to laptop, enable USB debugging and see what happens.

OK...
So at the moment your PhoneUtil settings are UART>Modem and USB>PDA right? Leave it at this setting.
Now with the phone connected to you computer... Go to device manager and Uninstall any Samsung drivers that u would see in Device Manager (Windows). If you see anything like adb drivers then also Uninstall. If you have any other phone drivers (Nexus, LG etc), Uninstall those as well. Also from Control Panel>Uninstall a Program, Uninstall any USB drivers programs that u would see in the list.
Once u are certain you have Uninstalled all phone & adb USB drivers. Also Uninstall Kies completely. You might also need to disable Windows auto driver installer. Reboot ur laptop / computer.
Once computer reboots... Google for Samsung USB drivers for mobile phone. The version I used was v1.5.27. You can try with any version. Some people have had the best luck with v1.4.60. Install the drivers and reboot the system again.
Switch off ur phone. And go to download mode.
Then connect ur phone to the computer via USB cable and see what happens? Look in Device Manager again and see what is showing. Also try using a USB 2.0 port for best results.
Once done... Unplug the phone... Get out of download mode.... (u can simply put the battery out of the phone)... Or long press the power button... Let the phone restart. Plug the phone again to the computer and see what happens?

Oh and make sure USB debugging is Off when doing the above. USB debugging should always be Off... At least till ur pc detects ur phone.
Have the drivers installed on ur system before u are troubleshooting.

I'm facing same problem..
I have Korean version of S3 SHV-E210S..
Android version 4.1.2
Baseband version I9300ZCLK2
I've installed samsung usb driver, kies, and even adb driver installer..
But it doesn't help me at all..
Then i go to his thread, i tried to dial *#7284#, but nothing happen..
I've put it in download mode too..
And my pc can't detect my phone..
Please help me..
Sorry for my bad english..
Please read post # 12.
These are the only things I can suggest.
If all fails then your only option would be to download "Airdroid" from Play store.
It will not solve your issue but will let you transfer files to your phone at least

Did you download and install "Samsung USB drivers for mobile phones"? Any version should work. Make sure u install the drivers and reboot your machine.

while saving after selecting SUB -> PDA, phone should boot automatically.

Hello,
I recently installed Cyanogenmod on my phone using the CM Installer. Now my phone is having issues connecting to the PC. I want to try and troubleshoot the problem by turning off ( or on???) USB Debugging.
I push the Build Number 7 times. It brings up Developer Options. I go there but USB Debugging is not listed as an option. Other options are there such as...
- Android debugging
- USB debugging notify
- ADB over network
... etc.etc.
Does anyone know what happened?
Kind Regards
Cheers

What version of cyanogenmod have you installed on your phone (I knows it's install version, but have you updated yet?) What does android debugging say?
Today I've noticed that usb debugging automatically switch off after closing the developer options page. I enable it and if I go back it switchs off. If I enable it with phone connected all is right but if I unconnect phone from pc it switchs off. There is no way to keep the options enabled. Any tip ?
Thanks
EDIT: if in developer options you reset all settings that usb debug remain enabled until reboot. But if you reboot it's disabled again...
This phone is incredibly mad.... Enabling usb debug with phone connected and rebooting via adb, unplugging cable during boot, the option remain enable if you DON'T open developer options screen. If you do it it disables again.
I don't have words......

Enable the 'allow debugging in charge only mode' and it should fix the problem

You're great !!! All is ok now. Thanks a lot
I have Eedmi note 4 and my USB debugging(Security settings) keeps turning off when i come back from developer settings. My USB debugging is ON but below this there is another option called " USB debugging(Security settings)" which is used for simulating input via usb , and this option keeps turning off.
Is there an option to fix this issue, im on android 7.0 with miui 10.2.3.0 global stable ui.
