Karbonn A12+ All Things

Flipkart delivered my Karbonn A12+ three days back. The phone is a masterpiece to say the least. But looking at the development end of the phone, there is almost no dev support for the Karbonn A12+. Sensing that, I am starting this thread to spark some development for this device.

If you are unsure about buying this handset, here is a Detailed Review of Karbonn A12+. I have covered almost everything in the review, if you want to know anything else about the phone, do let me know.

If it doesn't work in first try, try again, worked for me with the exact same steps being repeated in the second try.

Clockworkmod Recovery:
I have successfully ported Clockworkmod Recovery for our Karbonn A12+ with the help of MTK Droid Tools. I have created a special zip file to help you through the process. The files in the zip are pretty self explanatory but if you need detailed instructions, refer this guide.

Stock ROM
Thanks to chukzde, here is the cwm flashable zip of the stock rom.

Here is MT6572 Scatter file for you to use while flashing any stuff using SP Flash Tool.
Please note that old versions of SP Flash Tool will throw an error like failed to initialize on this scatter file. This file works fine with the latest version of SP Flash Tool (latest according to what I could find on the internet).

Sound Mod:
Rooted A12+ (and other device) users can use Viper Sound Mod to improve the sound quality of the phone speaker or any headset you use with it. I have shared my experience of the Viper Sound Mod on the Karbonn A12+ here.

Key Combinations:

Press and hold Volume Down + Power Button to get into Factory Mode. Selecting the only option with some english in it will factory reset your Karbonn A12+

Press and hold Volume Up + Power Button to get to a menu. In this menu, use Volume Up to scroll and Volume Down to select. From this menu, you can go to Fastboot Mode, Recovery Mode or boot normally.

Additionally, the ID: COM box in Odin will turn blue with the COM port number indicating successful connection

Troubleshoot issues

Sometimes the device does not boot into Recovery Mode and root the device. If this happens, then perform the entire procedure again. If it still does not install root, ensure Auto Reboot checkbox in Odin is not checked. Then after flashing the root package, pull out the battery and boot the phone into Recovery mode by selecting Volume Up, Home andPower buttons together. This will start the install process.
