I have an HP Pavilion dv4-1431us running InsydeH2O BIOS F.66 Rev. 3.5 (extracted from sp48847.exe). The main BIOS file is 30F7F665.FD.I’m trying to install a Realtek RTL8188CE WiFi card (HP P/N 639967-001, SPS 640926-001, PCI ID VEN_10EC & DEV_8176).I followed the classic whitelist removal guide (the one with EZH2O / WinHex / debug + changing 75 to EB) and also tried the modern UEFITool method:
Any help would be greatly appreciated. Thank you!
- Searched the full .FD for the 104-U string (31 00 30 00 34 00 2d 00 55 and the shortened 31 00 30 00 34 00) → not found.
- Extracted all 9 PE32 modules with UEFITool 0.28.0.
- Searched every extracted .bin for my card ID (10 EC 81 76), common Broadcom IDs (14 E4), Atheros (16 8C), and other Realtek (10 EC) → nothing found.
- Re-upload the TTAV134 mod for these exact files, or
- Mod my 30F7F665.FD to remove the WLAN whitelist (and preferably WWAN too)?
Any help would be greatly appreciated. Thank you!
