This short video shows how you can use Mobile Uncle Tools app to flash a custom recovery (or the stock one) on any Mediatek Android device.
Extract this file and replace the recovery.img in it with the recovery.img you want to flash. Copy the recovery.img and recoverytools.apk to the root of your phone/tablet's sdcard.

Note: By default, the zip file I linked above contains the recovery.img file for Karbonn A12+. Flashing this recovery.img on Karbonn A12+ will install clockworkmod recovery on it.
