Hello everybody!

Sorry for my bad english, this is google translate :(

I have Lenovo x240:

 

  1. Many thanks to Klem. He removed the WWAN and WLAN whitelist in my x240 bios.
  2. I replaced WLAN: old ac7260 with new ac8265 - super !!! I wanted to put ax210, but unfortunately it haven't a drivers for Windows 7, for Windows 10 only.
  3. Replaced WWAN: old em7345 with new em7455 - problem:
  • when turning on or restarting the x240, a sound signal and an error appear:

2101: Detection error on SSD1 (M.2)
Press Esc to continue

 

  • after pressing ESC, Windows boots, em7455 works fine !!!

In interface m.2, the bus is configured using the output pins of the plug-in modules. See Product Technical Specification em7345, em7455, ssd-disk:

Spoiler

 

em7345:
CONFIG_3 (01) - (GND in default module configuration)
CONFIG_0 (21) - (NC in default module configuration)
CONFIG_2 (75) - (GND in default module configuration)
CONFIG_1 (69) - (GND in default module configuration)

em7455:
CONFIG_3 (01) - (NC in default module configuration)
CONFIG_0 (21) - (GND in default module configuration)
CONFIG_2 (75) - (GND in default module configuration)
CONFIG_1 (69) - (NC in default module configuration)

SSD-disk:
CONFIG pins are set by the SSD to inform the host if the drive wishes to use the SATA or PCIe signaling scheme. SSD-SATA pull pin 1, pin 21, pin 69, pin 75 to Ground.

 


To eliminate the sound signal and the appearance of an error, it is necessary to glue or paint over with varnish 21 pins of em7455.

I can't find switch option from TPM 1.2 to 2.0 in Secure Chip Tab. I have installed Windows 11 on original Bios, some time ago, but on UNLOCKED I just can't find this option. I checked ME CONFIGURATION, but this way made changes doesn't save. I put orginal BIOS again, and BETA version works fine. Regards

Hi!

Ok. I checked your file bios dump, unfortunately it's not correct. You need to read your bios dump from your bios chip again, may be multiple times and compare in any hex editor (for example HxD), all dumps should be identical.

If you will meet with some problems with read bios dump from your bios chip, then try to use different software version.

All software versions for Ch341A programmer I placed into this link:  https://files.fm/u/7t7pbeehq

I recommend you use software AsProgrammer_1.4.1

      In this thread you can post your requests for Lenovo ThinkPad L440.
      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.
