@hungry4cheese Would you please tell what is the model number, is it A2005?

I downloaded the picture of Step 12, the picture clearly shows it is QCA6164 (with 1T1R) rather than 6174.

However, I run software tool lspci, pci vendir-id / device-id is : 168c:003e which means qca6174. qca6164's device-id is 0041 (not 003e). This contradicts with the picture.

My oneplus 2 is A2001. Wikipedia says there is A2003 and A2005 too. I am not sure if this picture is taken from A2005 or Oneplus uses different chips in their different shipment.
