I did the whitelist removal and unlocked the advanced settings as well.
Since Intel WIFI wasn't possible at the time I got mine I had no other choice. In order to apply a modified Bios you need to disassemble the Notebook (the Bios Rom Chips are near the CPU on the top side of the Board) and use an external SPI Flash programmer to flash the modified Rom. After flashing the ROM I was able to replace the build in Intel WIFI Card with an DW1550 (Broadcom WIFI/BT Combo Card).
where can I find modified rom. do you still have griven
