[REQUEST] Lenovo IdeaPad S400 (6DCNxxWW) Whitelist Removal

[Fred34]

First thinks for your help, it was usefull (not the link but your files)
I've finaly manage to downgrade my Bios with your files and a backup found on this thread that never be OK before.
If it can help authers, I had to modify a value in my bios : desactivate "Bios backup" (I don't remember exactly the terms, but only one in the bios with those 2 words)
I don't solve my problem of black screen : I suppose it's due to the EC Version that haven't changed : 6DEC96WW(V8.09).
So I search the file to downgrade EC version but not found yet. It seem's that this file should be about 8Mb...
I don't know if it's possible to backup EC firmware from an other lapetop (S400u model 6312 in my case)
If I find, I'll post the solution but If someone can help me....

Hi friend,
the EC Image is not possible to backup normaly only using an SPI PGM HW and desoldering Chip from MoBo !
So We have to check a way to use Original to Reflash It and force Reflash All !
Actualy there are too much Protections and Reverse is not easy to find a way to bypass all controls.
In Original Bios You'll find to files 1st for Bios 2nd fo EC, but We cannot modify them to reflash as there are
checksum and signature to lock modifies, so using Intel FPT We can bypass them.
For Lenovo IdeaPad S400U there isn't any original Update Bios File !!!
That file can be used but only by SPI PGM.
