I'm sorry to say, but than there is nothing we can use. If there is no valid MAC addresses out of the Xiaomi poll stored by at this offset, we are not going to use this offset.

Feel free to rewrite your factory partition on your own and apply the missing pieces for your board but is nothing that we are going to support by default.
