Default [HELP] Stock Recovery of Huawei Ascend Y511-U30

I have installed CWM recovery over my stock recovery. Now I want to revert to stock recovery but I am not able to find appropriate stock recovery for my Huawei Ascend Y511-U30 device. I want to flash stock firmware which I have downloaded from Huawei Russia website but my CWM recovery is not recognizing it and update fails. Any suggestions?

Can anybody help me?
