Hi,
I replaced the TPM 1.2 module of my T440p by a TPM 2.0 module, but it fails to boot with 4 cycles of 4 beep meaning there's a problem with the security chip. I made sure to use a TPM which also uses the LPC interface, with the same PIN's at the same location :
The original TPM : https://static6.arrow.com/aropdfconversi...94dm00.pdf
The new one : https://www.infineon.com/dgdl/Infineon-d...d1d3054feb
Could you help me circumvent this boot error ? If possible, a Wifi whitelist and an unlocked advanced menu would be awesome.

Thanks a lot !
