Macbook Pro A1502 13 EMC2678 820-3476-A EFI unlock

Hi, I managed to remove the EFI lock following this tutorial but upon OSX install it is now asking me for a 6 digit passcode.
i think this macbook is tied to an iCloud account.

how can i bypass this ? am I missing a step or is this iCloud locked motherboard that can't be unlocked?

Procedures:
detached EFI chip with hot air
Firmware dump using - EZP2010 SPI programmer
verified firmware - ok
executed scan-n-patch.pl
programmed firmware back to EFI chip

Holding Command + R
no longer shows pad lock
select WIFI to begin restore MAC OSX
asking for a 6 digit pin to unlock to proceed with install
