Default How to make boot.img or flashable zip file from a firmware zip file

Good day everyone!

I got a 201hw from Softbank.
It's basically an ascend p1 lte (Huawei). It is not a 9202L but a 9201L btw

I'm pretty tired of the stock rom. The phone will block all 3g network whenever i change the sim..

The only firmware i could download from Huawei is this

HUAWEI Ascend P1 LTE Open Source(U9201L,IcecreamSandwich,kernel-3.0.8)


And that thing is not flashable, when i tried to view it with winrar, what i got is in the attachment

So what can i do with it ? How can i make a boot.img or a flashable zip from it?

And yes i'm a completely newbie!

Thanks in advance!
