After using rooted devices since I switched to android. I took rooting Qmobile A2 as a challenge. I did this for my self and now sharing it for other users of Qmobile Noir A2 getting desperate for root access, here it comes

I take no responsibility whatsoever comes to you. However, I have personally tested this on my QMobile Noir A2 with following specs:

Hardware : MT6575
Model : A2
Build number : ALPS.GB2.MP.V2.2
Build date UTC : 20120621-045853
Android version : 2.3.6
Baseband version: MAUI.11AMD.W11.50.SP.V14, 2012/04/20 13:54
Kernel version : 2.6.35.7 (wuhai@SW3-Server) (gcc version 4.4.3 (GCC) ) #1 Thu Jun 21 11:55:57 HKT 2012

Before you proceed, make sure that you have MTK6575 and your recovery partition has the same start address and size. Otherwise the recoveries here won't work for you. The recovery partition address starts from 0x0980000 and has a size of 0x00500000 (5 MB). You can check yours using MTKDriod tools or by typing "cat /proc/mtd" in terminal (or using ADB shell).

Note: In this guide a few of the stuff has MTK6573 string, but this doesn't mean that it will also work for MTK6573. I intentionally put MTK6573 for a reason.

In order to root you QMobile Noir A2 (MTK6575), follow these steps.
1) Getting things ready
a) Extract "Noir_A2_Root_Package.7z" all parts (1, 2 and 3)
b) Copy "CWM-SuperSU-v1.04.zip" to your sdcard.
c) Install drivers from "MT65x3 USB VCOM drivers" folder.
2) Install CWM recovery
a) Turn off your mobile (remove battery)
b) Open SP Flash tool, click "Scatter-loading" and select file "MT6573_Android_scatter.txt".
c) Make sure ONLY "RECOVERY" is checked in partition and "recovery(CWM).img" file is selected.
d) Press "Download" button, and quickly connect your phone using a usb cable (first insert battery, if removed in step 2-a). It will start flashing the recovery. Once it is done, you will see a notification and a Green Circle.
3) Gain root access
a) Boot into recovery by holding "volume +" and "volume -" and pressing the power key.
b) Select "recovery mode" from the options. You SHOULD see recovery menu in a while showing "CWM v5.5.0.4 for Android 2.3.x" on top.
Here, it is recommended that you backup your entire system to sdcard. So that you have something to come back to, incase you mess up.
c) In recovery menu, select "install zip from sdcard" -> "choose zip from sdcard" and select "CWM-SuperSU-v1.04.zip" file from sdcard, go for YES option. Wait for the flash to complete.
d) Now select "reboot system now" option. Wait for the phone to reboot to normal mode.
YOU SHOULD NOW HAVE A ROOTED PHONE with SuperSU app installed, if you followed the steps correctly.

*In case you were unable to boot, restore your system from the backup (if you created any).
**If you want to go back to stock recovery, flash "recovery(Stock).img" using SP Flash tool.

To backup, go to recovery select "backup and restore" -> "backup".
To restore, go to recovery select "backup and restore" -> "restore".

I am not really the creator of this method, I just connected some pieces to get a working method. Most of the guide was extracted from various sources, considering the fact that QMobile Noir A2 and Fly IQ245+ are identical at hardware and lower-software level, just branded and boxed. I wanted to post links to the references but it is not allowed.

Update: CWM recovery 6.0.2.7 thanks to mega_man for contribution.

Here are the screenshots of the Rooted QMobile A2. I have superuser app instead of SuperSU. With the above root procedure you will get SuperSU

There is unroot option in SuperSU app. Moreover if one creates system backup in recovery, before installing CWM-SuperSU-v1.04.zip, he can restore original system partition from recovery later.

@hasan1987
Well this is the only QMobile device I got like a week ago, So, Don't expect me to know much about QMobile smartphones.
Though I have a little background of HTC and Samsung Android devices

@hammyboy
I generated scatter file from ur firmware info and what i got is that the start address (0x980000) and size is same. Partition wise your phone is good to go. If your Kernel version matches, then there shouldn't be a problem at all.

Were you unable to root with other methods?
