Is there a simple way to create cwm update.zip file from OTA update.app?

Not a "simple" way. It's a bit involved.

You have to dump the system.img from the update.app, mount it, zip the contents, a custom META-INF and the boot.img.

Thanks, Dazz. How do we dump system.img? Are there any tutorials for that, I couldn't find any. Is there a literature for android programming that I could dload? Thanks again for making this phone better with your work.

update.app is Huawei's custom file format and it is completely undocumented. That said, I use a script to split the file up in the correct way.
