Folks.. Now you can root your HoneyComb 3.1 in the same way of rooting, how you use to root before. This is done in a little different way.. and is revealed by a XDA member, “|OP|”. It’s for Acer’s Iconia and is working fine.. Enable USB debuggimg and then follow the steps mentioned below to root 3.1 Iconia

  1. As we told it’s different, goto Settings>Application & Enable “Unknown Sources”
  2. Asusually copy the .apk attached file to your device
  3. Install  .apk file and run it
  4. Hit Root

After that your SuperUser comes to home screen and you are rooted.
