What you will need is Bin4ary's One Touch Root App
. This app will get you only partial root via the ADB Shell. My guess is the ADB exploit he uses does work to get basic root access for ADB, but some incompatibility prevents proper installation of su & SuperUser.apk. What we're going to do is finish the job manually.
First run Bin4ary's app and use the Normal Method. Be sure to ignore all errors. After your tablet reboots move su and Superuser.apk from Bin4ry's app folder to the root of the Internal SDCard. Next you will need ADB. If you don't have it you can get it either from Bin4ary's app folder you found su & superuser.apk in or you can install the Android SDK. At the command prompt enter the following:
At this point you should see a # sign indicating root privileges. If you do enter the following commands.
mv /system/xbin/su /system/xbin/osu
cp /sdcard/su /system/xbin
chmod 6755 /system/xbin/su
The use Astro or your favorite file manager to navigate to /sdcard and install SuperUser.apk then reboot your tablet. From here on you should have full root on your tablet. Credit should definitely goto Bin4ry for his work on his One Touch Root App for getting us half way there.
The Nextbook 8 (NX008HD8G) is a $99 tablet available from Walmart. It sports a AMLogic AML8726-MX SoC (1.5Ghz dualcore Cortex-A9 w/400mhz dualcore Malli400 GPU), 1 Gb of DDR3 RAM, 8" display, and 8Gb internal storage. Its a nice little budget tablet for those who don't need a Nexus 7 or greater performance rated tablet. Not too long ago I discovered how to root it and apparently I'm the first to do it as far as I can tell. Now here's how.
