@DarkWorld - Sorry I lost your thread until now!! Verified Boot is enabled at PCH (Intel Boot Guard), but it looks like maybe DXE BIOS volume is not protected - If you have programmer we can test edit if you want.

@cryptopsy - See above, do you have flash programmer? If not, it's huge risk of not being able to recover from brick if boot guard does cover the volume we want to edit. It doesn't look like it, but I can't be 100% sure (99.9% sure though)

If you both want to try anyway, watch this thread and see if we get past the locks stopping us from writing back via FPT, then if so we can try.
Unlocking 280 write protection in X1 Carbon Gen 3 for NVMe support


* Edit - I checked around to see if anyone flashing mod BIOS on these, and I see whitelist and unlocked menu BIOS here, so boot guard does not cover the regions we need to edit as I suspected

BUT, if we can't get past the locks you will need flash programmer + SOIC8 test clip

@Lost_N_BIOS : Hi there! I am new here on the forum and to BIOS modding, but hope you can help me.

I also got X1C3 and did the biosreg.bin. Please find it here:
... error ... need more posts to add links. Can I send you a PN please?

Intel ME Version is 10.0 and the Boot Guard is enabled.


What are the next steps I should take to get my laptop to support NVME?
Thanks in advance!

Whoops, I completely forgot I made a thread on this!

Thanks for taking a look at it, but unfortunately this laptop is currently OOS with a smashed screen, otherwise I'd have taken up that offer :P

@ag4189 - Sorry for the delay, I just replied to you PM as well!

Once I see your BIOS region, I will either tell you we can't mod, or I will give you new info to dump a certain volume not covered by boot guard (if you are lucky)
I looked at DarkWorld's dump, and it looks like we can do NVME insert, but I'll have to have you do dump differently since we can't write entire BIOS region.
Here, make new dump with this command and send me this file too, along with the biosreg.bin I asked you to reupload in PM
FPTw.exe -a 0xA00000 -l 0x3F0000 -d DXEVOL.bin

@DarkWorld - Find cheap screen on ebay, order from china and wait, then you can fix easy

Thanks for your reply and welcome back! I hope you are well recovered. :)

I have done the second dump. I will send you a PN with the link, because I still can't post any here.
-----------------

Okay, strangely enough I can't send PNs anymore. :(

@ag4189 - You're welcome!!
Maybe some glitch, about the PM's? I got your PM, checking now.
Here, flash this back via >> FPTw.exe -a 0xA00000 -l 0x3F0000 -d DXEVOLNVME.bin
http://s000.tinyupload.com/index.php?fil...239711467392973

If you see any red or "Size" error, DO NOT Reboot, take a screenshot showing command entered and error, then flash back in your original DXEVOL.bin

Then follow instructions at step #4 in the "Installation of the OS onto NVME" section of this guide
[Guide] How to get full NVMe support for all Systems with an AMI UEFI BIOS

I have a X1 Carbon 3rd (20BS), too.

While looking for a way to mod the BIOS to add support for NVME SSD, Google brought this thread to me. I am expecting a hero find a correct way to add support for NVME. Please, if possible, finish this mod. Thanx.

BTW, Several years ago, I bought one IPS panel from China to replace the old TN panel. It's not hard (I can't say very easy) to replace the LCD panel.
