Full, Permanent Root for Acer Iconia Tab A100 on ICS
It has taken a while for the development community to come up with full, permanent root for the Iconia Tab, but now it’s there. In collaboration with vdsirotkin from 4PDA.ru, XDA member ZeroNull recently unveiled his one-click root utility which allows for functions many users have been long been waiting for, such as read/write permission. The script can be run either from a Windows or Linux computer, and looking at the instructions, it seems to be a pretty painless process.
The feedback is great. Almost all users have achieved root without any issues, and according to ZeroNull, “no errors were found while testing.” It is important to note that this root works only when your Tab is updated to Android Ice Cream Sandwich. You can find the script and details in the root thread.
