Hi

I have an S3 i9305 lte that was originally on T-Mobile. I rooted the device and since then I cannot connect to any PC. I have used over 20 different USB leads in different ports and still not connecting. I get nothing on the screen to identify my phone is connected so I cannot change it to or from camera mode. I have tried USB debugging on and off, tried to connect to Kies and now have installed the official 4.1.2 that was downloaded from a reliable source. My phone says it's not rooted now but I am still unable to connect my phone to my PC. I am coming to a point where I am just going to sell it and get another phone.

Can anyone give me any advice please as its doing my nut in!

Thanks

Have you tried on another computer? i had similar problem with my desktop, no matter what i did it wouldn't recognise my phone. tried on my lptop and it recognised straight away. the point is you have to illiminate the pc is not the problem...

When I rooted mine I forgot to do this and had the same symptoms...

Restore USB Settings after Backup / Restore:

•Dial *#7284# on your phone to access PhoneUtil and select 'Qualcomm USB settings' at the bottom.

Now select 'MTP + ADB' and press 'OK' to return to the previous screen.

Now press your 'Back' key to exit PhoneUtil.

Your phone is now back to default USB operation.

You absolute star! I was about to take it to the repair shop where they quoted me £50 to fix it! I bet they get this kind of thing all the time and mugs like me pay it!

Cheers mate,

Your more than welcome, as you are no longer rooted may I suggest this..

I upgraded today in 13 mins and it now sings.

It's a lot easier and only requires one file
