I can not vouch for other methods but I have rooted this tablet with SuperOneClick ver. 2.1.1. If you leave "Exploit" on "auto" and click "root" you will be pleasantly surprised. Took me two tries, but if you turn on usb debugging in settings and leave the screen timeout on 30min your golden. Happy rooting.... I'm also uploading a google apps zip file. I unzipped it and installed all the files in the corresponding places to get a working Android Market. I used Android Commander to move the files & install apk's. *NOTE* You need to install the apps in the "/sysem/app" folder in this order...
After... Restart, Connect to wifi, and launch Market. You will be prompted to sign in to google. Then you will see Market License blah blah blah...
*Use the attached zip not the one at the following link* But use this link as a guide if you need it... http://forum.xda-developers.com/showthread.php?t=827209
*Zip File Link*
****THIS METHOD WORKED FOR MY IMPRESSION 10 MODEL # i10-50, but UNTESTED by me on other models****
***EDIT*** Sorry guys... you were unlucky because I forgot something crucial.... THE DARN ADB DRIVER.... You will need to go into the device manager and right click the "Android" device with exclamation mark & click update driver. Search for the driver and point the installer to this folder should work on 32 & 64 bit if my edits are correct... Tested on 64 bit Windows 7.
Also when you install those "/system/app" files above use Android Commanders "Installer" and install them one at a time in the order above. AND AFTER YOU RESTART USE LAUNCHER AND NOT SETUP OR YOU CAN'T ACTIVATE YOUR WIFI.
