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:
Code:
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 Because it is outdated.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.

CWM-recovery
Download: http://files.androtab.info/rockchip/...S18-03_CWM.zip

From adb root shell
1. extract flash_image and recovery.img from CWM.zip
2. put flash_image and recovery.img into device, e.g.
adb push flash_image /dev/
adb push recovery.img /dev/
3. enter root shell (adb shell)
4. flash recovery.img into recovery partition with flash_image, e.g.
chmod 755 /dev/flash_image
/dev/flash_image recovery /dev/recovery.img

Read this when you have any issues
CWM installation problems, please try another method if this doesn't work for you.
Link: http://androtab.info/clockworkmod/rockchip/install/

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\andr oid_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:
Code:
;------------------------------------NTx86------------------------------------
[Google.NTx86];
For loopback testing
And add this after the first space of declaring hardware ids;
Code:
%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

Tested and working on the following devices:

Audiosonic T-17B 7" tablet (Kmart webshop version) ✓
S18-03-XXXX (4.9.2013) ✓
S18-03-201302 (4gb-00905) ✓

S18-02-XXXX (x.x.2012) ?

Thumbs up How about S18-02-xxxx ?
I got myself a S18-02-xxxx, The ADB drivers behave oddly for this gadget. The driver installs, but SuperOneClick can't locate the device.

It does have SuperUser installed, but only the .apk file, not the permissions required to run it.

Think you can setup something?

Can you get access to adb shell and what os are you running? Modified adb doesn't seem to work properly on windows 8 you need to change this in order to make it work for windows 8 i think (at least you can try).
Start -> Run -> Type: "gpedit.msc" (Without quotes) -> Computer Configuration -> Administrative Templates -> Windows Components -> Application Compatibility -> Turn off Application Compatibility Engine <- Disable this

It might be the S18-02-xxxx. Model 02 has another soc i think, can you download a app in the play store for me? Type in: "Cpu info", download and install -> "CPU / RAM / DEVICE Identifier". And tell me what soc you have in it. Because the older versions may have a a9 amlogic 8726-m3l soc in it.

Please try that and verify if that worked for you or if you get adb shell access. Thanks,
and sorry for the late reply.

Just wanted to confirm I have successfully rooted my Audiosonic T-17B &" tablet (AUS KMart version) using your guide!

Although I'll note that the BAT file didn't succeed for some reason. Manually following the commands worked fine though, but I didn't bother with CWM as yet.

EDIT: Figured it out. It's the 'exit' commands you've stuck in there, it terminates the whole batch command instead of just restarting ADB. Can you edit that and re-upload the zipfile?

Seems like a bug.. in the forum software handling the bbcode..

Just remove the <br /> at the end of the url and it works.


And my content does not even include <br /> == space/enter ...



FYI. PROBLEM IS SENT TO FORUM ADMIN.
