Hi,

I have previously tried to unlock my BIO on my T450s, but was only partially successful.

I was able to remove the display whitelist, but I'm still unable to remove the network card restrictions

Would you be able to help?

Thanks

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.

      I've been scouring the internet in search of anything regarding an updated bios for my Clevo P170SM. I have found many mentions of Prema Bios mods on various websites, but good luck trying to find actual download links. They all seem to vanish or have dead links. Wayback Machine doesn't help either and I was only able to find stock Clevo bios as early as 2015 via the WayBack Machine. If anybody has an updates Prema Bios or some other unlocked bios file for the P170SM, that would be fantastic! Otherwise, I might have to consider paying over $100 to Eurocom for their unlocked bios.
