Revert to normal recovery mode from CWM recovery mode I am using Micromax Canvas 2.2.

I wanted to install a custom ROM on it, so I backed up the the original ROM (normally, without using CWM recovery). After that, I installed CWM recovery mode on it. Then, I wiped my data &amp; cache and installed a custom ROM, but I forgot to backup the previous ROM using CWM! Now, when I wanted to restore the previous ROM, it is impossible!

The previous backup is a .backup file &amp; CWM can't restore it. I have to restore it via normal recovery mode, but whenever I turn on recovery mode, CWM mode automatically comes there! How to restore my previous ROM?
Just flash stock recovery.img file through Mobile uncle tools.
But in case you want your stock rom back, this will not be helpful to you.
You will have to flash stock firmware through mtk droid tools.
