This BIOS has a "BIOS Back Flash" option which can be enabled/disabled (default is disabled). The description reads "Allow BIOS to be back leveled to a previous version." Does that help?
So far I see no way in BIOS to utilize this "BIOS Back Flash" feature.
I will try the test posted above with the option enabled, just to see what happens...
FYI: I tried the TESTBACK.exe with the BackFlash option enabled and same result as SpidrJeru had. I guess this means we know how to read the BIOS image but not write back a patched version.
I would eventually like to eliminate locked MSR (PmPatch) and remove (or change) the WiFi whitelist.
I 'd like to replace the 7260 N Wifi card with an Atheros AR5BHB116 card.

find BIOS update for IdeaPad U330, but I'm not sure that BIOS from u330 compatible with u430p. Does anyone know how to check compatibility?

Look README to update. Please post results.
Unfortunately, flashing not finished due error:
Error 280: Failed to disable write protection for the BIOS space!
This error show twice - once after start flashing and second after I press enter after first error.
I try to enable or disable "Backflash bios" function, but flashing not sensitive to this changes

Maybe ... this mod can be flashed with HW programmer only.
sad but I haven't hw programmer
There is a chance that it will change if Lenovo published bios update for my model?
I 'd like to replace the 7260 N Wifi card with an 7260AC card.

Can be done by force flashing by recovery
