I just realized that it is possible to do it with CH341A, reading with MX25U25635F. Thanks to the comments above ...

[B]Hello, I have a[/B] [B]Lenovo ThinkPad L15 Gen 3
type 21C7-001FMX s/n - pw-032x94

I need some help, what do I need to reprogramming this type of bios with? Correct me if I am wrong, but I have the CH341A but it does not support it.
