[REQUEST] Lenovo X220 (8DETxxWW) Whitelist Removal

[Jonaldinho]

I tried this Bios and I still get the error, is there something I'm missing? X220 4286-CTO 8DET76WW (1.46)
I did the white list only version. If it was successfully install would there be any way to tell other then not getting an 1802 Error?
I was trying to use the same card that was in the machine just from a different manufacturer Intel N6205, I also tried a N6230 with no luck. Multiple 1802 errors.

No need to whitelist, I just saw post up for 1.46 bios.

With my X220 previously on official Bios 1.46, I always receive the error

"Verifying BIOS Fail! Reflashing"

when flashing ** Lenovo X220 v1.46 Modified Bios (full-blown) ** under Windows 7.

Computer not bricked, modified bios seems to work, but there must be some binary mismatch...

Any ideas what might be the reason, and what is not working ?

I got the same message several times and I started the search to find the solution with another computer but when I come back to the x220
the process finished and I can not find whether the process completed successfully.
I started with Lenovo v1.46 and currently it is showing the same version number, but I can see the Advanced tab.
I do not remember Lenovo v1.46 had a Advanced tab?
How can I check the update process has completed well or not?

Hi all

I have an X220 with latest OEM bios 1.46 8DET76WW and me_cleaned with small -s parameter. All is working fine, Intel ME disappeared, but there is however a slight but reproducable delay in boot compared to OEM bios without me_cleaner applied. It's like a 7 extra seconds needed to have the stock lenovo OEM bios image appearing. I am quite confident the stock bios is waiting on some feedback of the disabled Intel ME. Did anyone look into these delayed boot times when me_cleaner is applied on stock bios? Would be nice if we could patch the OEM bios to get rid of the delayed boot time.

Will do some research myself this week and flash all bios versions to see if the delayed boot times are consistent for all previous bios versions.

Where is the time / date? It can not be seen after the item of Advanced has increased.

Thought I was going crazy!!! Date Time is nowhere to be seen after flashing this modded BIOS.  What's up w/ that???? anyone?

for the record i too was getting verifying bios fail reflashing message.

Thank you to @ValdikSS and all the other contributors.

Say I don't care about Spectre mitigation, just maximum performance: going through the stock BIOS changelog, 1.43 was the last version not to include any Spectre-related fixes, and that's the one I've been considering to flash.

I understand the modified BIOS version 1.43 and 1.46 (the newest) is basically the same patches reapplied to different stock BIOS versions with minor changes. One such change, mentioned in #381, is the Video BIOS, which was version 2119 up to and including 1.43, and version 2089 from then on, since the higher version was found to be unstable on Linux. Since I'll be using this laptop with Windows only, am I correct to assume that the higher version is otherwise preferable?

Were there any other changes to be aware of (bug fixes) between the two versions of the modified BIOS? Which version is the best to use if Spectre vulnerabilities are not a concern? Thank you for the clarification.
