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

Recommended Posts

In this thread you can post your requests for Lenovo ThinkPad T440p / T440s / T540p.

If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, then you can post your request in this thread.

Important!

For creating bios backup and to flash 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.

Hello Klem!

I recently acquired a Lenovo T440P, and would appreciate if you could help me get the WLAN whitelist removed, as well as the Advanced Menu unlocked.

I used a SPI programmer CH341A to dump my BIOS from W25Q32FV chip.

The dump i sent you via PM.

Thanks, and I appreciate any help!

Hi, Klem!

I used my ch341a_spi to dump my bios from my W25Q32.V chip in my T440p. I just sent you the BIOS dump via pm. Would you be able to modify it to get both the unlocked BIOS menu added and the WLAN whiteless removed?

Thank you!

Hi,

 

I have Lenovo T440P, It has been locked with Supervisor password on BIOS chip winbond 25Q32FVSIQ (1414). Is there a way to remove the password, so that i can enable Wireless LAN in BIOS setup.

 

Thanks,

Karthik sha

Hi!

No, unfortunately unlocked bios can't help you with Supervisor password.

Hi, I've got the SPI programmer and tried to dump the bios, but the clip was constantly 'sliding' off of the chip.. I'd assume there's enough space to get a grip without removing the whole base cover, but right now I am not sure if the issue is with my fatty fingers or do I really need to disassemble it to get the clear access to the mobo?

Hi!

Unfortunately, I can't remotely help you connect the SOIC8 clip to the BIOS chip. If you can't connect, and you see that something prevents you connect, you can try to disassemble the laptop.

Was rather thinking that someone who dumped it would chime in and tell whether they had to remove the bottom base or not :) Thanks, will tear it apart tonight and will get back to you when I have the dump. Thanks! 

 

OK I was able to dump the bios, send you a PM.

Hi guys & modder,

 

I am about to buy SPI programmer and test clip to flash my bios. I am doing this to enable my laptop to install egpu.

My lenovo t440p is the one with core i5-4200u.

 

Just checking if the thread is still active (if there is any reply after my post :p)

 

I'll attach the dump later.

 

Thanks!!

Hello, did anyone have any issues using flashrom via linux seems... ch341a_spi is supported https://www.flashrom.org/Supported_hardware#Supported_chipsets

 

Curious if all these cheap ch341 programmers are all the same, and behave the same for flashrom to pickup the usb device correctly.

 

I also found this debian based program https://github.com/setarcos/ch341prog - but if the more widely used flashrom works, may as well use that.

Hello Support,
 
I have a T440p Lenovo laptop, and forgotten the BIOS Super password, please can you advise if BIOS password can be removed?
 
What will be the procedure, will it require opening the laptop motherboard etc or just through software programming?
Can I do it myself if you provide steps and instructions?
How much will the service cost and how much time will it take to unlock the laptop?
 
Thanking in advance for your response.

Hi, I'd like to upgrade my wifi card and access the hidden bios settings.

 

I have uploaded a bios dump here: https://www.dropbox.com/s/kqkkap4vcptze6o/t440p.zip?dl=0

 

I've upgraded the CPU to a 4810MQ already and plan on installing OS X. Please advise if there are any other BIOS tweaks you would recommend.  Thank you so much for your help!

      Hello everyone, it is 2020 and i've been looking literally EVERYWHERE for a modded vBios for an Asus G751jy (980m 4gb) to unlock voltage control above 25mV, can someone help me?

      Hi,
      In this thread you can post your requests for AMD-V unlock on ACER E5-553G and same laptops with AMD CPU's, for example Acer Aspire E15, Acer Aspire E5-523G, Acer Aspire E1-522, Acer Aspire E1-420, Acer Aspire E5-421, Acer Aspire V5-123, and etc.
       
      Now we can unlock  AMD-V function for virtualization support. In general, this method described in the article on this link: http://www.geektech.co.nz/how-to-unlock-...enovo-y700
      This way requires Windows as a system because  some tool works only in Windows.
       
      Download this tool: https://drive.google.com/file/d/0B4NHIBM...RtQXM/view
      Extract the archive H2OUVE.rar directly on the Desktop and copy the H2OUVE folder directly on the disk C:\
      Then run the Command prompt as Administrator and execute these commands:
      cd  \
       
      cd  H2OUVE
       
      H2OUVE.exe   -gv   vars.txt

      After each command press the Enter button.
      After that, you'll have the file "vars.txt" in H2OUVE folder.
      Post here this file "vars.txt" or upload it to any fileserver and  send me the link.

      For reference, here's the EFI-table with available settings for this notebook: https://drive.google.com/open?id=0B4NHIB...WI4LW14bE0
      And here's the setting that needs to be changed:
      0x1C40B             Setting: SVM support, Variable: 0xEE {05 91 54 02 55 02 54 00 34 12 EE 00 00 10 00 01 00}
      0x1C41C                 Option: Disabled, Value: 0x0 (default) {09 07 27 00 10 00 00}
      0x1C423                 Option: Enabled, Value: 0x1 {09 07 28 00 00 00 01}
