[REQUEST] Lenovo IdeaPad U330, U430 & U530 (7CCNxxWW) Whitelist Removal

[RehabMan]

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.

-My laptop: Lenovo Ideapad U430p (Model name: 20269)

-Bios type: LENOVO 7CCN26WW, 06.09.2013


- Bios download link: BIOS updates not yet published by Lenovo. I 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?

- Intel 7260N card (original): PCI\VEN_8086&DEV_08B2&SUBSYS_42628086&REV_73\0C8BFDFFFFB710C900

I get BIOS backup by TESTBACK.exe, as described in this topic: http://www.bios-mods.com/forum/Thread-RE...s-7CCN26WW

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?

Can be done by force flashing by recovery
Need a full BIOS backup to mod and reflash tought
another option is external EEPROM programmer

Edit:

Also, have you guys tried prr2 utility to bypass write protection in BIOS region?
