Dead NAND -- repair options

Hi. I have a working iphone 6s logic board with a dead NAND chip. I have a replacement chip, and a programmer. However I understand I need to pre-program some information into the new NAND (mac id, bt id, etc) for the phone to work again.

1) What is the minimal set of info I need to preprogram into new NAND ?

2) How can I extract the serial number or IMEI number from a logic board with dead NAND to look these up? Or alternatively get it's MAC and BT addresses?

first what programmer do you have?

if you are using JCPro1000s the old NAND you can read and save the info from the old NAND, then for the new NAND you can write the information that you save in the programmer.

if it happens that you just change it without writing the old info you cannot activate in. it will show "Unable to activate"
