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!!

Hi!

Yes of course this thread is still active. When you create your dump, you can post it here with your request.

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!

      I have a iBuypower CZ-17 laptop, with a 2012 AMI BIOS that has E1762 as the version, which I believe means I have an MSI G70 motherboard. It has a 675MX GPU, but it's not useable in Windows 10 despite being "seen" in the device manager. I believe an updated, unlocked BIOS would fix my issue and have located the thread on this site with the BIOS I need.

      First of all, am I right? Will this fresh BIOS make my laptop that originally ran Windows 8 work with this old GPU?

      And second, I created this account, will wait 24 hours and made this post. Is that enough to allow me to download the file, or do I need to post elsewhere?

      Thanks!

      A part of my BIOS got corrupted that controls my laptops backlights. Other methods like the Gary Key fix did not work for me because I do not get any light up during post. i followed this guide  that says I need to extract and use the 6MB portion of an 8MB bios dump, only AFUWIN tells me "Error, ROM file size does not match existing BIOS size which is because my laptop BIOS size is only 5.87MB.  I don't need to flash the whole BIOS, I only need to flash a portion of it. 
       
      I've searched everywhere online for a dump of my laptop model but non exist that I know of.

      I fiddled around with modding my laptops BIOS to unlock XMP profiles and hopefully seeing if optimus could be disabled. After flashing my modded bios and trying it out, I noticed that my keyboards backlight no longer turns on. I was unaware it requires an official BIOS to function. They backlights wont turn on unless ASUS ATK package is installed but now it seems it also needs an official BIOS?
       
      The modded ROM and tool I used if anyone has any experience with this and doesn't mind telling me what to enable/disable, or anything else i can do to re-enable them

      To install the unlocked bios, I prepared and booted a freedos usb. I start the installation by typing flash.bat but every time I get the following error: Error 28: Protected Range Registers are currently set by BIOS, preventing flash Access. Please contact the target System BIOS vendor for an option to disable Protected Range Registers.
      How can i solve this problem ?
