Hi I just got my Galaxy S4 unlocked and it seemed fine, then I went to connect it to the computer on Vista and normally it opens up a box asking if I wish to add pics, videos etc, a box appears on the phone asking if I wana charge or connect phone. Even if it doesnt come up you can find it manually threw my computer.

Now I got it unlocked I cant find it connected to the PC, Its not in my computer and when I went to system devices, and it comes up as Device Unknown, and says

! CDC Serial
! SAMSUNG_Android
! SAMSUNG_Android
! SAMSUNG_Android



I dont know whats wrong I cant connect the Phone what is wrong how do I sort this thankx

Whoever unlocked it broke something. SIM unlocking has absolutely nothing to do with connecting to the computer. It's like not having oil in your engine gave you a flat tire - there's no connection between them.

Hi thankx I dont think its physical more software related, I had no idea unlocking was harmeful to samsung galaxy as it as on iphones
It also doesnt let me do software update for phones (does let me update apps) after the unlocking too.
