Make sure your phone is rooted. Copy the recovery.img file to the root of sdcard. Download terminal emulator on android ur android from market(its a free app). Open terminal emulator and run the followin command :
flash_image recovery /sdcard/recovery.img
Then reboot the device if it doesn't do it automatically...
Well my device is totally blocked, can't reboot into recovery at all tried every possible thing. I'm planning to buy a new phone... Budget 10K any nice phone?
