Hi all.

So I manage to port this ported rom to my device.

Ported because it was originally ported to the "Star N9500" by Olidan

So all credits to him/her. Donate link is to Olidan account as the work is not mine.

The ROM is to be installed from CWM recovery following instructions provided below.

And I quote the work done:







Lenovo OS Rom port


This is the version to install from CWM recovery






Links to everything that is required for proper installation can be found in the following paragraphs.




Features of the Lenovo OS Rom


This is not a Lenovo-style Rom … this is a real porting from Lenovo S820!

The ROM is very beautiful and functional… testing only a few things I found it very smoother and faster, and now one of the most performance that I worked on.
I left with all the original functions Lenovo, including Supercamera and Supergallery Lenovo … 13 MP of perfection,
a definition never seen before, razor-sharp images and autofocus perfect!




I adopted a kernel modified by me to make the Rom even more powerful.

The Rom is multilingual.


Follows a list of the main features of the Lenovo OS Rom:

*  Root

*   Deodex

*  Kernel (boot.img) modified with real support init.d

*  Zipalign at every boot

*  Sqlite optimization at every boot

*  Very smooth, with no lag

*  Absolutely full app in the system, it was not removed anything from the original version

*  Extremely stable

*  Gapps already installed

*  Optimized to the maximum

*  New Boot Animation

*  New Logo initial

*  Build.prop optimized

*  Gps.conf optimized

*  Scripts and Tweaks listed in the following section




Scripts & Tweaks


After careful selection and long and patient work, in order to adapt to this device and delete all the conflicts I could insert different and will list only the main ones:

*  Adrenaline Engine

*  Loopy Smothness

*  Geeky Engine

*  Net-Fork

*  Supremacy

*  VelocityTweaks

*  SlaidyBoost

*  BeatsAudio

*  CosmisTweak LightSpeed




Introduction to the installation of the Lenovo OS Rom


You may have already downloaded the zip file from the link above and copied the zip file in SD card.
Restart your device in Cwm recovery and make a backup of your device.

Then always from Cwm perform a full wipe:
->  Wipe data / factory reset

->  Wipe cache partition

->  Advanced ->  Wipe Dalvik Cache

->  Advanced ->  Wipe Battery Stats

->  Mounts and storage ->  format system

You are ready to install the Lenovo OS Rom from Cwm with the usual:
->  Install zip from sdcard.

Will start the installation process with the touch controls.

At the end of this at the request of the installer confirm that you want to reboot into CWM recovery, and from here again:

->  Wipe cache partition

->  Advanced ->  Wipe Dalvik Cache

Reboot. Upon reboot follow the wizard to set up the language and the basic settings of the phone and then run a new reboot (there are some services that to start, needs a second reboot). And now enjoy!!


Only bug for now (that I found) is that google maps wont work.

And some parts of menus wont change from english, despite that its working like a charm and very stable for my GT99.


※Please make a backup of your device before installing or updating ROM

    In order for google maps to work you need to first unnistall it with Titanio Backup or any other app with root permissions.

    Then use Root Explorer and go to: Root->System->Framework->delete:   com.google.android.maps


    Leave Root explorer and go to play store and download and install google maps, should work fine now.

    Enjoy this awesome rom…
