Could you please be so kind and help me to clear the WLAN whitelist and unlock the advanced menu in Lenovo T540p? It has two BIOS chips, 64Mbit and 32 Mbit. Both dumps are available here:

Hope they're fine.

Hi!

What BIOS did you try to flash? After which BIOS did your laptop stop turning on?

¡Hola!

¿Qué BIOS intentaste actualizar? ¿Después de qué BIOS dejó de encender tu computadora portátil?

I tried to flash the 8mb and 4mb one, it left the 8 and 4mb files of my bios, I would appreciate it if you could help me with this.

If you read both your BIOSes

correctly, without errors, then when you flash them back (correctly, without errors), your laptop should turn on and work without problems.
