My Galaxy S2 decided that he would connect to PC anymore.

The things that I tried:

  1. with 3 cables.
  2. on 4 computers.
  3. cache partition clean.
  4. restore to factory defaults.
  5. clean the micro USB port with tooth brush.
  6. restarts, shut downs and battery removes (about 20 times).
  7. external SD card and SIM remove.

What more can I do?

I've looked on other forums to see if others are experiencing the same thing and found some but no one else mentioned having upgraded via Kies Air. I have tried plugging in to different computers and used different cables. I don't know if the update is a factor, but it seems so to me due to the timing of my –  user30557 Mar 19 '13 at 18:49
