there is two way to solve it

***************************************************************************
The first way is for installing factory ROM

try to change your recovery version

download this version of recovery:
http://www.mediafire.com/download/n3zl9i8i764hu6y/recovery.img
install and reboot


if you don't know,how to change it, do the following:

download the ADB Folder from here:
http://www.mediafire.com/download/qyd9oimyo1q6yyd/.android.rar

extract it to c:
after that,you must have this folder c:\.android

copy the "recovery.img" that is downloaded from first link to the .android folder and do the following

1- go to c:\.android and press shift and right click and select "open command prompt from here"

command prompt will shown. after that use this commands:

2- C:\Android>adb devices
this message should be shown:
List of devices attached
Micromax-A56 device

3-C:\Android>fastboot devices
this message should be shown:
COOLPADA7019 fastboot

4-C:\Android>fastboot erase recovery
this message should be shown:
erasing 'recovery'... OKAY [ 0.109s]
finished. total time: 0.156s

5-C:\Android>fastboot flash recovery recovery.img
this message should be shown:
sending 'recovery' (4436 KB)... OKAY [ 0.406s]
writing 'recovery'... OKAY [ 0.813s] finished.
total time: 1.219s

6-C:\Android>fastboot reboot
this message should be shown:
rebooting... finished. total time: 0.016s


while rebooting press +volume key to enter installed recovery and install the original version of micromax a57 from zip file from SDcard. like this one:
