Here I give you a 100% working root method if you using linux:

If you try this, you do that on your own risk!!!

1.) Download android-tools-adb (Android Debug Bridge CLI) from the respositories or google

2.) Now download the ARM-zip from http://androidsu.com/superuser/

3.) Unpack the zip-file and copy the files "su" and "Superuser.apk" into your /home folder

4.) Download busybox from http://forum.xda-developers.com/attachment.php?attachmentid=624175&d=1307984755 and unpack the file

5.) IMPORTANT: Delete now all files and folders from the unpacked Superoneklick, you just need the busybox. In this folder is also a "su" and "Superuser.apk". DONT USE THEM.

6.) Now connect the tablet with your computer and ignore the posibility to use it as a mass storage. Just push the back-button and set the tablet in a debugging-mode.

7.) Open a terminal on your computer and follow the code line by line without sudo!

• adb devices
• adb root
• adb remount
• adb shell mv /system/bin/su /system/bin/su.old
• adb shell ln -s /system/xbin/su /system/bin/su
• abd shell
• # mount -o remount,rw -t rfs /dev/block/st19 /system
• # exit
• adb push busybox /system/bin
• adb push su /system/bin
• adb push Superuser.apk /system/app/
• adb shell
• # chmod 4755 /system/bin/busybox
• # chmod 4755 /system/bin/su
• # mount -o remount,ro -t rfs /dev/block/st19 /system
• # exit
• adb reboot

Now you have a rooted device. Good luck!
