[Android General] u.k-f:
Hallo!

I want to to show you how I gained root-access to a Point of View Protab 2.5xxl Tablet.

I only tell you what I did with my device, without any warranty. If you do the same to your device, you do anything on your own risk. Doing these things might end up in a damaged device. When you are not sure what you are doing, do NOT the same to your device. I do not promise anything, I just tell you what I did

I needed a Windows 7 PC whit an installed java JDK 1.7 (If I would not have this, I would download it from java.oracle.com)

The main problem hereby is not the process of the rooting itself, but getting ADB able USB Drivers.

First step

: I download the Android 4.1 firmware from the vendors webpage:

http://downloads.pointofview-online...XXL/TAB-PROTAB25XXL-Android 4.1_201212011.zip

Then I extracted the zip-file and followed the Instructions to update my Device.

Second Step

: I download the Android SDK from here:

dl.google.com/android/installer_r21.0.1-windows.exe

I installed the Android sdk on my Win7 Computer by doubleclicking on the installer_r21.0.1-windows.exe and startet the Android SDK Manager.

I took some time to load a ist of available packages, and the I could select

Tools->Android SDK Plattform-tools

Extras->Android Support Library

Extras->Gogle USB Drivers

and I pressed the button 'Install 3 Packages'

A Dialog opened and I checked 'Accept All' and pressed the Button 'Install'. I waited to complete...

Third Step

: I checked in the Settings of my Protab:

Security->Allow install from external sources

Developer->USB Debugging

I connected my Protab via USB to my PC and opened the Device Manager.

I selected my device which was marked with a yellow warning sign. With a right-click on it I got the context menu and choose 'Properties'.

In the 'Details' tab i selected the Property 'Hardware Ids' where I found the values VID_18D1 and PID_0003

Fourth Step

: I opend Windows Explorer and navigated to the folder:

C:\Program Files (x86)\Android\android-sdk\extras\google\usb_driver

I opened the file 'android_winusb.inf whit my texteditor and copied the lines

%SingleAdbInterface% = USB_Install, USB\VID_18D1&PID_4E21

%CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_4E22&MI_01

and changed the copy to those values:

%SingleAdbInterface% = USB_Install, USB\VID_18D1&PID_0003

%CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_0003&MI_01

So it matched the values I found in the properties of my device.

I saved the changed file.

Fifth Step

:

In the Device Manager I right clicked on my device and choose 'Update Driver'. In the Driver dialog I selected to 'Browse my computer for driver software' and pressed Next. At the point 'Search for driver software in this location:' I navigated to this folder:

C:\Program Files (x86)\Android\android-sdk\extras\google\usb_driver.

I choose to install this driver software even it is not signed.

After this step my Device was correctly recognized by windows.

Sixth Step

: Now I followed the Instructions from Bin4ry to root my device:

I choose option '1 Normal', followed the instructions and after this, my tab was rooted...

I hope it was interesting for you to here what I did...

If you do the same, you do it on your own risk! I do not recommend you to do the same

Kind regards, Uwe
