In this thread you can post your requests for Lenovo ThinkPad T450s, T460, T470, T480.

If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, or already upgraded Display and after that can't adjust screen brightnessthen 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.

Hi!

Yes, you can send me (via PM) your bios dump which was made using any SPI programmer, or upload it to any fileserver ( for example https://www.sendspace.com/  )  and send me the link.

Hi Klem,

 

I just bought a t450 and was curious about what hidden features this unlock gives us? I understand the benefits in the whitelist and seeing that the M.2 2242 drives are so pricey I think a high-speed 4g card might be the best upgrade option instead of storage.

 

Thanks in advance
