I HAVE AN X240 CARBON, I need a bios menu unlock and whitelist removal,
i have a discrete tpm 1.2 and intel ppt option in the bios, i have disabled the option but i am aware this makes the modding procedure more complex.
i have attached a copy of a bios dump created with a tl 866 pro programmer, i removed the chip and did 4 dumps and all married up with the same md5 hash.
I want to unlock BIOS hidden options in order to change DVMT-prealloc. My model: Thinkpad X240 BIOS versions: GIET86WW 2.36 File: https://www.dropbox.com/s/32uppf9fk3hqk5...l.bin?dl=0 MD5: 5ED182A1D67484EF9DA0D8F94B5D6883 I know that this laptop's bios chip is rewrite protected so i have already bought SPI-programmer+SOIC8 clip to dump the flashable BIOS file. And i have already changed the whitelist mac address in order to use broadcom wifi card. Some bugs after this, for example i cannot press enter to go into setup( it will be blackscreen and soon boot into OS), only f1 or f12 works. This bug doesn't annoy me, just don't know why, because i only change the mac address The uploaded BIOS is also dumped from SPI-programmer so i wish the modded bios can be flashable, too. I cannot completely remove whitelist due to my poor skill, delete LenovoWmaPolicyDxe.efi will cause blackscreen and cannot go into BIOS. That's not so important, but i will appreciate it if you can get it done too
Thanks in advance!
I've got the same laptop as you and just flashed my bios as well and im facing the same thing. Just black screen upon boot, can't get it to post. What's the solution?
