Smile [Q] huawei y300 local.prop help please.

Hi, im new here, sort pf starting out with the small amount of knowledge that i have.

So ive rooted said phone without gaining the bootloader unluck code from
Huawei themselves, that said, the root was successfull.

I heard of a trick to edit the local.prop file to gain higher data speed etc.by editing hsdpa, hsupa etc, i used it on my old phone
And it worked great, the trouble im having this time is that i cant find the local.prop file.

So i set some permissions and created one, to no avail, the file created but was empty.

Any help to find the file would be greatly appreciated.

Thanks in advance
