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.
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.
How to to it:
Just new to this forum I would like to ask if it is possible to remove the whitelist protection of my Lenovo Thinkpad Yoga 260 notebook.
So I can mount my own WWAN SIerra wireless card to the Yoga.
I think I have all the tools (SPI prgrammer and so).
Dump of BIOS is attached.
Correction: max file size is 1MB, so it is NOT attached, but I have it available of course.
I would love to have my BIOS modded to disable the wireless whitelist.
I tried to do it myself (dump BIOS from chip, disassemble, locate the reference to the error message "Unauthorized Wireless network card is plugged in..." memory address and modify the condition in the binary file so not to "land" in the infinite loop) but I couldn't dig to anything meaningful I could easily change.
