Hi!

Yes, you can post here or send me your bios dump, or upload your file bios dump into any fileserver and post the link.

In Lenovo ThinkPad T450s, any modified bios can be flash using hardware SPI programmer only, exactly the same as described in the first post of this thread.

So, for creating backup (dump) of bios you need to use hardware SPI programmer only.

Ok, thanks. Here is the link to the bios dump:

yup, the BIOS that I uploaded to Mega I took it out of my laptop with the SPI programmer but as I modify it so that I only make the whitelist of the screen?

Ok. Have you replaced your original LCD with another and then lost the brightness control?

Hi Klem. Can you help me with T550 BIOS? I think there is some CRC error. I've tried to remove password, and failed...

Last time you helped me with T440s and it worked with some help from my friend.

 

This is oryginal T550 taken with CH341A.
