Huawei P9 Wi-fi and Bluetooth Problem (NOT A SOLUTION)

My Huawei p9 worked great for about a month after I purchased it, but then suddently wifi and bluetooth became inaccessible. I contacted the retailer that sold the phone to me, and, after advising me to factory reset my P9 and do troubleshooting (neither resolved the issue), they concluded that it could be a hardware malfunction and told me to send the phone for repairs to them. Judging from the new scratches on my phone, it seems like they disassembled it and probably changed the internal wiring or the antenna. After all, wifi and bluetooth function very similarly and most likely even use the same external antenna in the phone!

iPhone 6 WiFi & Bluetooth Antenna Rep... - that's probably how my Huawei got fixed. I'm pretty sure that you can do something similar to this with Huawei P9, but I would not risk it.
