Hello,
I want to disable the WWAN whitelist on my X270.
I have dumped the original BIOS firmware, applied this patch: https://github.com/digmorepaka/thinkpad-...hes_v7.txt
(full copy in attachments)

with
flashed the patched firmware, got the Advanced Menu with overclocking and all other stuff, but the WWAN whitelist is still in force - the laptop does not boot and shows error "1802: unauthorized network card" with a 3rd party card. If I put the original WWAN card the laptop boots normally.
If you know how to correctly disable the WWAN whitelist on X270 then please share.
Also there is another small issue - the laptop complains about incorrect time/date and wants me to adjust it but I could not find where to change the time/date in the patched BIOS. It is not on the 2nd tab as it was in the original BIOS (as far as I remember) and I wasn't able to find it anywhere else, could you advise how do I change the time/date?
