QUANTUM7+/TABTRONICS ( RK3066/JB 4.1.1) – ROOT

Just to share the experience. This is what worked for me...

All the CREDITS and THANKS go to the “digitalhigh” – for the post below (and the guys in the chain..):

1. Android SDK Manager (used the following versions)

Android SDK Tools - Rev. 21.1

Android SDK Platform Tools - Rev. 16.0.2

2. Modify File (as explained in the original post):

C:\Users\<YOUR-PC-USER>\.android\adb_usb.ini

- add a line:

0x2207​

3. Install USB driver Win 32/64 respectively - they are attached in the original post above.

!Note:

ignore

PushThese.zip, attached in the original post – not required – as the “adb shell” gets the root on device straight away. Also, the “Superuser.apk” and the “su” in this attached .zip are not compatible with JB 4.1.1, that is installed on the device. The “Busybox” is also already installed on this device. You can download and update this later from “Google Play”... Hence, just do not use this .zip related step.

4. Download “Superuser-3.2-RC3-arm-signed”

Download the following “Superuser-3.2-RC3-arm-signed” package from location:

http://downloads.noshufou.netdna-cdn.com/superuser/Superuser-3.2-RC3-arm-signed.zip

Unzip and copy “Superuser.apk” and “su” to the“adb” directory:

C:\Program Files\Android\android-sdk\platform-tools\

5. Tablet to PC:

“Developer options” → “USB debugging” → [v]

Connect Tablet to PC. Kick off the USB driver installation (if not yet done in Step 3).

From the Win command line:

cd C:\Program Files\Android\android-sdk\platform-tools\
adb devices

The device should respond as 0123456789ABCDEF, or something similar to this.

6. This is the “Step 15” of the original post with the "busybox" push skipped, just the small changes specific to the device:

adb shell
# mount -o remount,rw -t rfs /dev/block/st19 /system
# exit
adb push su /system/bin
adb install Superuser.apk
adb shell
[B]# chmod 4755 /system/bin/su[/B]
# mount -o remount,ro -t rfs /dev/block/st19 /system
# exit
adb reboot

7. Once your QUANTUM7+ rebooted you should have the “Superuser” app installed.

8. Install “Terminal Emulator” app from the “Google Play” and try to $ su. You should see the “Superuser” app permissions request etc., etc...

9. Update “Busybox” from the “Google Play” to the latest version.

10. I would suggest you to do the full nandroid backup as soon as you have rooted your device. You can look at this link or details (if interested in):

http://tips4droid.com/make-nandroid-backups-on-android-without-booting-into-recovery/

11. Just one more thing to say – by coupling 2 CPU cores, switching Governors to “interactive”, the I/O Scheduler to “noop” and extending the SD cache buffer to 4096, you device should easily outplay TF201 on the “Quadrant Standard” benchmark test.

Good luck!
