My Samsung GS3 has stopped giving me the notification that I connected to my PC. It still charges, but I can't access my files. It's been happening for a few months. When I cable up, after a second, it chimes audibly (pong-ping), but the pitch fork icon for USB never shows, there is no notification, the PC never does anything. Drop box works, Wi-Fi works, NFC works, Phone works. Samsung model SCH-I535 running Android 4.1.1 on Verizon. I have not rooted, or ROM’ed but this may take me past that brink.

I've tried::
Numerous PCs and USB cables
USB debugging (& Stay awake & Unknown sources) checked and unchecked
Unmounted & remounted SD card
Asking the PC to look for new hardware
Removed and re-installed PC drivers both from Verizon
(Verizon_Wireless_I535_GSIII_Samsung_USB_Driver_v1_4_6_0.exe)
& from “Samsung GS3 Int ToolKit”
(SGS3_International_ToolKit_v6.0.exe)
:: but nothing has fixed it.

Please don’t tell me to use a Wi-Fi app, Kies, All Share Cast, or S Beam. I want my phone USB fixed.

Does the phone show any notification? Sorry, wasn't sure if you meant the pc doesn't show any notifications in your post. Only other thing I could think of is a full reset after deleting all traces of Samsung and Verizon software from your pc.

The only response to USB cabling up was the audio "bell" from the phone. There was no response AT ALL on the PC and the notification window did not change. No USB symbol either.

However, thanks to another forum , I have the solution , as follows:
1. Remove phone from PC and remove battery to shut off phone.
2. Plug USB cable into PC.
3. Plug USB cable (other end) into phone.
4. Put battery back in and boot phone but…
5. As the phone boots, hold down Volume up and down.
6. This should reboot phone into download mode.
7. PC should install some drivers at this point.

Phone was in safe mode, but another reboot changed that.
Their must be some magic in that old silk hat you found. Opps, sorry, wrong song.

Thanks;

Try a different usb cable and also try downloading the drivers from Samsung website.

Sent from my SCH-I535 using Android Central Forums

Try connecting and disconnecting the cable several times. I have to do that sometimes.

Although I did not say so in my 1st post, I also tried Samsung direct download.
