Hey Guys,

I need some help, I think I came to the right forum [Image: smile.gif] I'm trying to install a new network card in a Lenovo G50-45. It tells me that it's unauthorized.
Could you help me with whitelisting my bios? I've uploaded a backup from my current bios. If you need anything else than please let me know since this is my first time.

Thanks in advance!

Ok, I have been trying this for a week or two now. I have my bios dumps. I have the clips and everything is in working order but I can not get my G50-45 to boot after flashing any sort of modded bios. I've tried my own and also had some very patient helpers as well. I will post my dumps, and
post the modded version I have. Maybe someone who knows more then I will know what is going on.

Here is the modded version as I mentioned. Now it is worth noting that my hardware and software do work because I can flash back to stock and it work fine.

Thanks All,
if you did everything right, it's RSA signed bios, it cannot be modified in any way.

Greetings!
I am trying to install Intel 3160 wlan card in my Lenovo G50-45 80E3 with AMD A8-6410 CPU.
I made a bios dump using Raspberry Pi3 and clips.
After that I modified the file by following this guide
https://medium.com/@p0358/removing-wlan-...033a5a5e5a
But with the modified bios my laptop does not start, just a blank screen.
Fortunately I was able to flash the original file back and laptop booted up.
If I understand correctly, I need to sign the bios in some way.
I couldn't find the TCPABIOS string in the file.
How to do it? Thanks in advance!
