Bios Mods -The Best BIOS Update and Modification Source

Hello Everyone,

  I wanted to upgrade my Dell Vostro 3446 WLAN card to a 5GHz card QCA9733. I brought it from aliexpress the card is ok, working on another laptop but it is not detected in my Vostro 3446. I don't know if my laptop has a WLAN whitelist embedded into it's BIOS. I backed up the BIOS using AMI-AFUWIN and also downloaded exe bios update then extract the BIOS it using "3446a15.exe /writeromfile" to 3446a15.rom. Then extracted the whole BIOS using Andy's Phoenix/Dell/EFI SLIC Mod Tool v2.58. Then everything is extracted into TEMP folder I opened up every single .BIOS file with WinHex and searched for PCIe VID and PID but no luck. I used these hex values:

BIOS DUMP: Download From Google Drive / [attachment=19636]

One strange thing I've tried. I read on a Reddit forum that if we put the card into the laptop after the laptop completely booted into the Operating System, the card might work. Guess what it is working but every reboot or a fresh start the WiFi card is gone and black listed by BIOS.



I have CH341 Programmer, I will post all the necessary files with detail in WLAN-Whitelist-Request forum on this website.

PLEASE HELP ME!!!
