[Upgrading, Modifying and Unlocking] NiTrOwow:
In this guide i will show you how to root a JXD S18 03-xxxx device.

This method was tested on the following device:

OS: Android 4.1.1

Kernel: 3.0.36+ Feb 2

Soc: Rk2926

Model: S18-03-201304-4GB-00727

Root:

0. Download files.zip(from here) extract it and open it in explorer.

1. Connect your device to your computer (micro-usb)

2. Unmount all storage devices (TF/SD card, onboard TF/SD, etc..)

3. Enable USB Debugging (Under settings > Options for developers > Enable USB Debugging)

4. Open ''AdbDriverInstaller.exe'' and install the universal ADB driver

5. Automated process for rooting the device ''ROOT ME.bat'' Press any key and just wait and let the tablet reboot.

6. Manual root:

adb shell
mount -o remount,rw -t rfs /dev/block/st19 /system
exit
adb push busybox /system/bin
adb push su /system/bin
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

And now you have root.

Make sure to update su(super user) after rooting. Because it is outdated.

You can either use adb push for this or you can use the Google Play store to download the latest bin.

If you have any issues while rooting please try:

adb kill-server

adb devices

And see if the devices is listed after killing the server.

If it is not than u may have another soc (older version does have other rockchip and the adb driver wont work properly).

This guide is for the latest version as if 1st May 2013: S18-03-XXXX (4.9.2013)

If you still have no output from adb devices you can try one more thing!

By editing android_winusb.inf in C:\Windows\System23\Drivestore\Filerepository\android_winusb.inf_amd64_neutral_<random_chars>

You will see two of those folders.

Open it with a text editor like notepad++ or notepad make sure you have nt authority rights

android_winusb.inf:

;------------------------------------NTx86------------------------------------
[Google.NTx86];
For loopback testing

And add this after the first space of declaring hardware ids;

%SingleAdbInterface% = USB_Install, USB\VID_2207&PID_0010
%CompositeAdbInterface% = USB_Install, USB\VID_2207&PID_0010&MI_01
%SingleAdbInterface% = USB_Install, USB\VID_2207&PID_0010
%CompositeAdbInterface% = USB_Install, USB\VID_2207&PID_0010&MI_01
