Dear Emly Dinesh,
I have used your firmware update for a machine that had the AR3011 and it worked very well.
I have a Lenovo Thinkpad twist that has a Broadcom 43228 which is a combo containing the BCM20702A0. I have taken your updater and modified it to add a vendor ID of 0x0a5c (2652 decimal) and a product ID of 0x21f3 (8691 decimal). However, this is not working.
I may still be making a mistake. Can you let me know if there are any kexts I should remove while I add your updater? I didn't need to do it when I did the AR3011 but maybe you have some suggestions.
Thanks for your help.
