Wifi problem (hardware)

Hi all

I own a Thl T11 phone that doesnt have wifi anymore

I tried different roms but i cant turn wifi On anymore unless i press really hard on back cover.

Can someone please tell me where is the wifi chip on this mtk6592 phone ?
Picture 1 & 2 are similar but i removed mt6605 chip which seem to do nfc ...

OK guys,.. I went for the oven trick.
Like my pizza: 400F for 15 min wrapped in aluminium foil
And I'm writing this msg from my working phone now...
Hope it will last. I only suggest this in last resort and remove everything you can before you "bake" a board
