I learned how to do this from here but it deserves to be in Android SE.
I did this from a Linux PC with adb
ADB installed. It may be possible from a Windows PC with adb
ADB installed but I could never get the tablet to connect as an installer over USB on Windows.
Turns out it was dead simple, really, it came rooted. Here’s how I installed Superuser on it so I can use apps that use root.
- download superuser.zip
- unzip superuser.zip
- adb root (to run adb as root user on the tablet)
- adb remount
- adb push Superuser.apk /system/app/
- adb push armeabi/su /system/xbin/su
- adb shell chmod 6755 /system/xbin/su
- adb shell ln -s /system/xbin/su /system/bin/su
- wget https://github.com/koush/Superuser/raw/master/init.superuser.rc
- adb push init.superuser.rc /
- Download superuser.zip
- Unzip
superuser.zip
adb root
(to run adb as root user on the tablet)
adb remount
adb push Superuser.apk /system/app/
adb push armeabi/su /system/xbin/su
adb shell chmod 6755 /system/xbin/su
adb shell ln -s /system/xbin/su /system/bin/su
wget https://github.com/koush/Superuser/raw/master/init.superuser.rc
adb push init.superuser.rc /
