Hi all,
I was disappointed to find that my new Micromax Canvas 2 A110 (then having Android ICS) was not supporting Malayalam. Then I heard the good news, Micromax released Jelly Bean update for it. Hoping that it would satisfy my need, I rushed to the service centre and upgraded my phone to Jelly Bean. DAMN!!, still no Malayalam. I was afraid to root my phone, because it will void my warranty. Then, out of desperate need, I decided to root. Here are the steps I followed. Before proceeding, read this twice - ROOTING WILL VOID YOUR WARRANTY. I AM NOT RESPONSIBLE FOR ANY DAMAGE OCCURRED TO YOUR DEVICE DUE TO ROOTING.

I have used Windows XP.

1. Get the drivers from here - http://www.micromaxinfo.com/download.ashx?section=mobile-A110&file=A110-Drivers.rar and install it.
2. Download ClockWorkMode Recovery image from here - http://www.mediafire.com/download.php?aak733itivap95w and rename it to recovery.img
3. Download Flash Tools from here - http://d-h.st/t5c
4. Extract Flash_Tools.rar
5. Go to the folder named SP_Flash_Tool_v3.1220.01 and run Flash_tool.exe
6. Click the button Scatter Loading. In the dialog box appeared, select the file named MT6577_Android_scatter_emmc.txt which is present inside the directory scatter file under the folder you just extracted.
7. Uncheck all other options except RECOVERY
8. Click on the checkbox RECOVERY. A dialog window will open. Select the previously downloaded and renamed recovery.img
9. Power off your phone and connect it to your PC. If a prompt appears for installing drivers, do it.
10. Remove your phone from PC. Remove the battery from the phone.
11. Click on the button named Download.
12. Connect your phone (with battery removed). If a prompt appears (again) for installing drivers, do it.
13. A green circle will appear showing the status of download. If download OK appears, remove your phone.
14. Let out a deep breath and say Hurray, you have installed ClockWorkMode on your phone. Now you can proceed to rooting. (Yes, we haven;t yet started it... )
15. Download Super User Binaries from here - http://download.chainfire.eu/310/SuperSU-v1.04.zip
16. DO NOT UNZIP THEM
17. Copy them to the root directory of your SD Card (of course after powering on your phone)
18. Power off your phone.
19. Press the Volume UP + Volume DOWN + Power buttons simultaneously to boot your phone.
20. Select Recovery Mode using the Volume UP and DOWN Buttons. (Touch won't work)
21. You'll reach CWM Menu. Here also touch won;t work. UP/DOWN for navigation and Power for selecting
22. Select the option Install zip from SD Card and select the .zip file you have moved to the root directory
23. If you see Installation complete, let out another deep breath.
24. Reboot your phone (normally, without pressing Volume Buttons) and have your fingers crossed.
25. If your phone boots fine, jump, dance and scream like hell as you have now successfully rooted your phone.

Now installing Malayalam fonts.

1. Install ES File Explorer from Google Play Store
2. Open it and click settings
3. Select Root Explorer. It will ask for Super User permissions, grant them.
4. On the navigation pane, click the / button to go to the root directory.
5. Go to system/etc/ and take backups of the files system_fonts.xml & fallback_fonts.xml to somewhere safe.
6. Download this file - http://goo.gl/mPx8u and unzip it.
7. Copy the files system_fonts.xml & fallback_fonts.xml from the extracted folder to system/etc and replace the existing files
8. Copy the file Kaumudi-Sans.ttf file to system/fonts folder.
9. Reboot your phone and again keep your fingers crossed.
10. Check if you can read malayalam. If yes, say HURRAY!!!
