Huawei p8max BT / Wifi / FM

I have looked around Sydney for anyone who can repair my p8max. I keep getting referred to their China phone numbers and website. I tried sending an email but that was weeks ago so I'm not expecting for a reply anymore.

The local Huawei official service centre said they are not capable of fixing this particular model since this is not available locally. Furthermore, I am predicting I will be charged a gold mine since this is not under warranty anymore as I bought this used from Ebay.

So that is the reason why I want to attempt to fix this myself.

The problem is with the Bluetooth, Wifi and FM radio functions. They all stopped working suddenly a few weeks back. I already tried flashing different ROMs hoping it was just a software problem. But no, none of the ROMs fixed the problem so I'm now certain it is hardware related.

The full product name is Huawei p8max (DAV-703L)
