[Android Software/Hacking General [Developers Only]] mickrick:
There are a lot of conflicting methods for rooting the Star N9500 on the web so this is my attempt to explain exactly what to do to root the Star N9500/MTK 6859 phones.

You will need:

PdaNe+t for pc (NOT Win8) or mac

Motochopper exploit

Optional for custom rom with android 4.2.2 and cwm recovery Many thanks to Petrucco and freedgt over at http://www.patrucco.com for the rom and assistance with installing and testing.

Flashtool

USB Vcom Driver

Rooting Method:

Download Motochopper exploit and extract to your location of choice.

Connect your phone to your pc by usb cable and turn it on

Navigate to the location of the motochopper exploit

Double-click "run.bat"

When it says "press any key to continue", do just that

If it stalls at "device found", start device manager and right-click a few times to bring up the menu with "scan for hardware changes" and click it

It should then install the drivers for your phone and the exploit should finish.

When it says "Press Enter to reboot and exit" do it

Your phone will now reboot and be rooted. Install SuperSU and a root checker from Google Play. Run the root checker and it should show the phone is rooted and you have Super User access.

Flash custom rom with cwm

This custom rom is really just the stock rom but upgrades to android 4.2.2 with a few added feature and tweaks. The camera app gives a lot more quality options and the gps locks on much faster. Installing it now gives you clockwork mod recovery (vol up + power) instead of just factory mode (vol down + power). You will need to check your lcd panel type before flashing as there are 2 types. Make a note - write it down!

Flashing Method (may remove root)

Download and install PdaNet+

Download and extract Star N9500 STOCK ROOT CWM 4.2.2 rom

Download and extract SP_Flash_Tool_v3.1308.0.125.rar

Download and extract usb vcom driver

Power your phone off and remove the battery for a few seconds

Replace the battery and leave the phone off

Navigate to where you extracted SP_Flash_Tool_v3.1308.0.125

Double-click Flash_Tool.exe

Click the "scatter-loading" button, navigate to where you extracted Star_N9500_STOCK_ROOT_CWM_4.2.2.rar (/Star N9500 STOCK 4.2.2/)

USE NORMAL SCATTER FOR LCD DRIVER LT050ANKP019A

USE SCATTER2 FOR LCD DRIVER 1-RX_499NT_598A

Press F9 or click the Download button. Do NOT click upgrade as this will semi-brick your phone!

Do NOT click upgrade as this will semi-brick your phone!

Do NOT click upgrade as this will semi-brick your phone!

Connect your phone to your pc by usb

Run PdaNet+ and install the usb vcom drivers

The phone will be detected and the flash will install:

A red bar will fill, followed by a purple bar, then yellow and finally a green circle showing the flash has been successful.

Exit the application and remove the battery from your phone for a few seconds

Replace the battery and hold the power button while holding vol up button

The blue android will appear - keep holding

The cwm recovery screen will appear with the recovery options. Release the buttons.

You navigate the options using vol up/down and select using the power button

After flashing this rom you may lose root access (I did), so download and install SuperSU from play store and check if still rooted. If not run the rooting instructions again to have a fully rooted N9500 with cwm recovery. ***UPDATE*** 4.2.2 rom leaves superuser intact.

If you're not sure how to use this guide, get someone else to do it for you. If there's anything I got wrong or missed out, let me know.
