I posted on here for assistance with removing the whitelist from my x1 carbon 2014 (2nd gen), and was contact via PM by a user here, who offered some assistance for a small fee, which I accepted.
I dumped the bios he returned using a raspberry pi, and it booted up and had indeed removed the whitelist, however due to a TPM security issue it now had 5 loud beeps, and a long delay on every boot, which I didn't like.
The user recommended I disable the security chip, the shut down, remove the cmos battery, boot to windows, then shutdown, reconnect the cmos battery, and it should all be fixed, however once i reconnected the cmos battery, the laptop will now not boot.
The power light flashes 3 times, and then it shuts off,
If I remove the cmos battery I can boot, with a message that there is no system time, and most tellingly
"bad CRC of security settings in EFI variable"
And of course i lose the time each reboot.
I tried flashing back the old bios, but the result is the same.
Is there any solution to this?? Or is this laptop bricked?
Many thanks for any help.
