By the way, this post was very old. Now I have resolved the issue after googling. Obviously one must have root privileges to install a custom recovery. Luckily Huawei Bootloader is unlocked so no need to worry about it. I had used FRAMA ROOT apk in order to root my Y511-U30. You can find its thread on XDA. For installing a CWM recovery I used its CWM img file in a Chinese apk called Mobile Uncle Tools. With that aok you can easily install flash CWM recovery and flash custom Roms which are many which you can find over internet.
If anybody needs any help regarding Y511-U30, please send a PM to me.
