@knubbze - Thank you so much for uploading the packages! I am traveling now and using the laptop for work, so I will have to wait until I get back home at the end of July to try updating the BIOS. I am going to try to replicate what you did to maximize the likelihood of success:

1. Update the BIOS to official Lenovo BIOS version 1.3 (6kuj12uc.iso)
2. Use WinFlash64 to flash BIOS with TRIM mod
3. Use WinFlash64 to flash BIOS with TRIM and Whitelist mod

Does that look right?

All the links I've found are dead.
I know there are a couple 1.3 BIOS out there with the whitelist removed but does anyone still have it?

Thanks

I have the files backed up on my NAS - I will try to dig them out over the weekend and re-upload them. In case I forget (likely), please remind me ;)
