I do not usually like to do things this way but I think you can find your EXACT model on ebay and someone can send you chip to replace it with. Get the chip and read it or email the sender to only give you the bin file and put it here so we can verify it for you. Then you can flash it to the mac.

Guys, stop please...
I did modified firmware with file attached to the FIRST messages message of this topic. This message posted by 'mrkktw' he is done from the forum perhaps his problem was solved. BUT firmware was from other MBA not form robin's. I was inattentive, and this is my mistake.
Robin, do you have a firmware backup EXACTLY from your MBA?

OK you can buy it on eBay, just pay $28 for it HERE . You can email the seller to ONLY send you the file and he will do so. Put a copy of the file here when you get it.
