I have been searching for about a week now and still can't figure this problem out. I bought this phone used about a month ago and I haven't tried to connect it to my pc until just recently. I am wanting to root and unlock my phone but I can't connect to pc using usb cord although it will charge it.

I am on GB 2.3.6 vuvkj6, stock.

I have tried 4 different usb cords, 4 different pc/laptops and all usb ports. I have also installed and uninstalled several usb drivers with no luck.

My phone can only get into download mode using a jig. Even in download mode, I can't connect to pc. I have tried using Heimdall, Odin, and kies but it just does not connect.

If I can use a jig to get it into dl mode, does that mean the phones usb port is fine?

I just want to be able to connect with pc. Is it possible to flash using my sdcard? I am thinking maybe the phone is missing something to pick up the usb signal or something.

I am lost, any help would be appreciated.

Maybe, I think it's a phone issue.

Do you still have a warranty?

I bought this phone used, so no warranty. If the jig works, does that mean the usb port is ok?

Does the phone charge when plugged in? Have you tried to go ahead and flash even though it says not recognized?

Yes the phone does charge when plugged in. I can't flash using Heimdall or Odin. Any other way of flashing?

I have also put the phone into debug mode with no luck.

Have you done a factory reset?

I am not sure what made it work for me. But what I did was "clear memory" on ram. I don't remember how I got onto that screen but I clicked on ram and clear memory.

I then pushed the usb into the pc a few times really fast until pc showed somethnig other than "usb device not recognized". Pc then started to show device connected.

if you are using windows i have found that sometimes the usb ports u used for the phone get stuck to the driver that was there in the first place. So what I do to fix this is go into device manager from the control panel and then uninstall the drivers for the specific port that I am trying to use. While keeping my phone unplugged from the computer I then reinstall the samsung drivers, restart my computer and then try to plug my phone in. 90% of the time that has been what works for me.

Ok, I figured out the problem. It has nothing to do with the drivers or clearing ram memory. My problem is the actual micro usb connection. If is a little loose from side to side and when I push it to one side, it connects no problem.

My phone is out of warranty. At least now I know the problem. It was extremely frustrating trying to figure it out.
