Hi I bought a secondhand iPhone 7 and is iCloud locked and, the guy that sold it to me is no answering my emails. My question is can I use a chip programmer to write or erase the information on the nand and unlock the iCloud ID? My friend has a nand programmer for iPhone 7/7p. What are the steps to unlock iCloud with a ic programmer?

Nope. The device identity is written into several chips, including the baseband. There is no way to rewrite these encrypted information, even if you could bu swapping out chips, the equipment and spare parts would cost more than a new phone.

Is it the same for an iphone6
