0x05 TPM error in read-only firmware on Samsung Cromebook XE

Postby jaroslavpsenicka » Sun Feb 08, 2015 5:45 pm

Hi all,

I've got the "0x05 TPM error in read-only firmware" on my Samsung Cromebook XE303C12, it looks like the TPM chip is dead and does not communicate. Is there a chance to bypass the chip, e.g. b flushing a custom firmware (and using Linux, because the ChromeOS requires secure boot)?

If so, is nv-U-Boot the correct firmware?

If not, is it possible to (unsolder and) replace the chip? I understand the chip holds the security key, so, it should be pre-programmed first?

Thank you,

Jaroslav
