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?
