But is 4G LTE possible in the T420 with Modified Bios?

#1 Post by A1Giorgio » Tue Sep 20, 2022 9:34 am

Greetings,
I have a T420, I modified the Bios, with this "T420_bios_1.52_NWL_ADV_0xE2_AES-NI_RAM_VBIOS_SIGN" thus removing the white list. In fact I have installed an unsupported wifi card and it works great !.

Now the only thing that makes me prope towards the T440p is the fact that I can't get any 4G LTE card to work !, I don't want to use the phone or external cards. I've tried 3 but none of them work. Beeps and the system does not boot.

Yet there is no white list in the bios installed! Why?

I also leave you the link of the post where I found the BIOS.

It's a mystery, I haven't found anyone that runs 4G LTE in the T420

I'm sorry for my english
