Recently one of my friends bought one of these tablets. When I
saw the tablet for the first time, I found myself playing with it
around 3 hours. Everything works perfectly on the tablet and it is
really responsive. I tried to connect to proxy servers and that was
the beginning of the story. The proxy app on the tablet that starts
with Psi...n tried to find servers. After finding servers for
connecting, an strange error occured:
Can not initailize service Interface.
and whole device mode did not work. I switched to browser only
and that worked perfect. But whole device mode did not worked
at all.
I digged the log and found out this line after the previous
error:
checking for root access: root access
denied.
After some googling I found that if the App is designed to
switch to iptables mode (for rooted 4+ devices) when it detects a
failure to configure the VPN Service. As mentioed in this topic on the google group,
when "Whole device mode For Android 4 +" fails, it is supposed to
automatically switch to "Whole device mode for Rooted Android".
After that, I googled again and found out that there are some
ROMs that required modules for some VPNs are not included in them.
It seems that the ROM on this tablet is like them! It's interesting
that there is a reository of these modules and an installer(
tun.ko installer) that based of the device specification,
download and installed requierd modules from the repository.
Unfortunately, the installer needs root access to work on the
device and I have no root access on this device yet!
When I found out that the proxy app is programmed to
automatically switch to "Whole device mode for Rooted Android" then
I decided to just root the device and let the App switch to
the "Whole device mode for Rooted Android" without furthur
installing missed VPN modules.
Rooting X-Vision tablet XL10 - 700G
Based on my revious experiences on rooting android 2.3 devices,
I searched google to find a way of rooting the device without
installing custom recovery. The Android version on tablet was 4.2.2
and I start googling with rooting
Android 4.2.2. All of them needs to unlock the bootloader
and adding custom recovery. One of my challenges was how to boot to recovery
mode on the tablet. I tried all combinations of the keys on the
device and no sucess. The device booted to recovery mode but no
menue apeared.
I continued seraching but these time based on the Rockchip base
board specifications. After a lot of not working solutions for
other tablets that was based on this rockchip based board, I
suddnely found the download section of
rockchip site.
In the middle of the page I found RK3066/RK3188 ROOT
Softwares. TPSarky Von Droid was one of them. The other one
is Moborobo versie 2.1, a nice app that tries to find drivers
of android devices and automatically connects to them. You can also
find Rockchip usb drives on the download section too.
Here is how to root the device (Please USE IT AT YOUR OWN RISK)
:
On Tablet do the followings:
1. Adjust Sleep settings:
- Settings->Display open sleep setting.
- Set sleep to at least ten minutes.
2. Enabling USB connection type (PNP, Mass storage and ...)
- Settings->storage->click on Three dots in
upper right of Settings window title field
- Select USB computer connection Dropdown menu .
- Select "Mass Storage" check box
- back out of storage settings
3. Enable installing of applications from unknown sources
- Browse down in Settings and select Security
- In Security Settings, Select Unknown sources, to give
the Android device permission to install software from
sources not specifically sanctioned by Google and the
Android Consortium. This ensures that the Root utility,
Tp-Sparky-Root.bat will have the necessary access rights
to root the u30gt. If you have any qualms about
unsanctioned files on your tablet or device, you will want to
uncheck this selection after the rooting process is
complete.
4. Enabling Debug mode:
- scroll down in settings and select {} Developer Options,
if not there, go to (i)about tablet.
- In Developer Options, select USB debugging.
5. Close settings, and any other open apps.
6. Goto the main android desktop, to ensure good
clean reboots.
7. Using a micro USB to std USB cable, connect the
tablet to PC (plug it in usb ort not host port on the table),
you'll get a "connecting to usb" in notifications area in
Android, and a usb icon in the notification area. You Do Not
want to select "Connect to Pc to Transfer Files", in the
notification menu, just plug in the cable and let it be.
On PC:
1. Download
RKBatchTool_u30.zip, the 1.5 version, from Rockchip download
section and unzip in a directory. Rk-batch-tool 1.5
has u30gt drivers, browse the Rk-batch tool's dir for the u30
drivers for your PC OS. Right click on the rockusb.inf and
chose Install, to install the driver. ( You can also fing the poper
driver based on you OS version on the download page
too).
2. Verify that you have a rockchip_usb USB Device under
disk drives in Device Manager. Control
Panel->System->Hardware-> Device Manager->Disk
Drives->rockchip_usb USB Device.
3. Download
TPSarky-VonDroid from Rockchip download
section and unzip in a directory.
4. Run, double click on, adb.exe first. It opens up a
dos command window, runs a dos executable that launches
adb server and connects to the tablet. It opens and closes
so fast you won't hardly see it. If you Do Not run
adb.exe. first, Tp-Sparky-Root.bat will not communicate with
the U30gt, and your root will fail.
5. Now run, double click on,
Tp-Sparky-Root.bat. Tp-Sparky-Root.bat will Immediately reboot
the tablet.
6. When the X-Vision XL10 reboots, hit space key as
instructed. Tp-Sparky-Root.bat will reboot the tablet,
again.
7. Press the space key as instructed, again. The command
line
will show
uid=0<root> gid=0<root>
if you have a successful root.
8. Press the space key as instructed, again. The
command informs you the tablet root has been remounted, there
are a couple of errors relating to SuperSU, I presume SuperSu
was Not included in the tpsarky zip file, or is in the wrong
place for the batch file to find it, but you can download
SuperSU from GooglePlayStore. The Utility notifies you
that Tp-Sparky-Root.bat is completing the root.
11. The tablet will reboot one last time.
I found this instruction for using Tp-Sparky-Root to root
a RK3066 based gadget named U30gt on the xda-developers site.
As mentioned there, it works for other RK3066/RK3188 based
devices.
After the rooting I installed
SuperSU from (finding the apk on the net) and granting
the root access for all apps needed.
Finally, I started the proxy app again and it switched to
the "Whole device mode for Rooted Android" and worked
perfectly in "Whole device mode".
