Lenovo ThinkPad T440p / T440s/ T540 unlocked BIOS menu / wlan / wi-fi whitelist mod

Recommended Posts

No, it hasn't since I sent the dump filled with only FF. It booted fine before.

 

I just tried again. When I connect it to power, the power button lights up and blinks every once in a while. Nothing else. Nothing happens when I press it.

Check again if you have assembled and connected everything correctly. If everything is correct, but the laptop still does not boot, it means that you somehow damaged your original stock BIOS dump. In this case, there is no point to unlocking it, because it is damaged.

I'm getting some fan spin, but that's about it.

 

Would you know if there is any way to fix the issue, besides replacing the chip or system?

Hello Klem.

I am a bit confused.
My T440P has a 1.18 BIOS, that has the whitelist.

I have found that the T440S has the 2.36 BIOS without the whitelist. 
And someone posted a "guide" on Reddit, saying that the 2.36 BIOS has no whitelist also in the T440P.

But this guy didnt reply anything and disappeared.

 

So, here my doubts, that hopefully you can clear.

- do you know if the T440P v 2.36 BIOS has the whitelist?

- (if NO) having the 1.18 BIOS, do i need to use the programmer to flash the modded BIOS? Or is just possible to update the BIOS as a standard operation?

- (if NO) what would be the best way to do? I mean, do i have to upgrade to the latest BIOS, share the file, you mod it and i flash with the programmer?
Or is there a better BIOS than others?

 

Thansk for your attention.

Yes of course, all original stock bios versions include whitelist.

Yes, in any case you need to use hardware SPI programmer. It doesn't related with bios versions.

It's at your discretion. And yes, I can unlock any bios version, but to prepare your bios dump, you need to use hardware SPI programmer. Read the first post of this thread.

Hi Klem,

 

Have a T540P and I've had some success with upgrading the BIOS. The advanced option is now there but the whitelist removal didn't work. Any advice would be helpful.

      Hi everyone, I have a problem. I need to unlock the bios settings because I only have basic functions and I need to increase the memory of VRam. Sorry if I posted a post not in this topic.

      In this thread you can post your requests for Lenovo ThinkPad X240.
      If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden advanced menus and settings in bios setup menu, or upgrade to new display (with brightness control), then you can post your request in this thread.
      Important!
      For creating your personal bios dump and to flash your bios mod, you must use any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip!
       
      Just dump your Bios using any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip, then post it in this thread or upload it to any fileserver and send me the link.
