[REQUEST] Lenovo B5400 (J7ETxxWW) Whitelist Removal

[brunob]

Hi there, same system as Dzacho above, but I would like the wifi card whitelist to be removed.

Name: Lenovo B5400
Manufacturer: Lenovo
Model: 20278
BIOS: J7ET63WW (v2.08)

BIOS backup (Universal BIOS Backup Toolkit 2.0 + NEW_BACKUP_FPT): https://www.sendspace.com/file/87la7h

But FPT 9.5 gives a test write error, so I'm not sure whether I can flash via SW or need a SPI programmer.

"Error 28: Protected Range Registers are currently set by BIOS, preventing flash access."

Thanks for your help.
