Modified BIOS 480 Code 43

[Lerrcey]

When I modify the BIOS of a RX 480 Sapphire Nitro OC+ I get a code 43.
Regardless of what I change or how little I change it will always Code 43 the modified BIOS.
I tried reinstalling the drivers with the modified BIOS on but it will not recognise it.

I am a little bit stumped.

The card still displays a picture through it even though it's not detected?

Stock / Backup works fine.

Anyone got any suggestions?

Cheers

Use drivers 16.11.5

Yes the last driver relive blocks the modified bios,
