It is a magic sequence to enable access to the flash controller registers, to prevent errant code writes to flash, it doesn't alter Read/Write protection on the array.

Yes, is there a reason why you have to ask this same question in four threads?

Suggest you review the IAP (In Application Programming) examples for your part. Build yourself a small loader that uses your specific type of 'Air' to transfer the data, and erase and write blocks of flash with this new data.
