I have an extended waranty that offers premium service, if they can't fix my phone in 5 business days they refund me the full price I paid when I got the phone.
So I need a way to damage my phone but it has to look like the phone was broken under normal usage.
Can I hardbrick it beyond repair? So they can't do anything to the phone unless they change the motherboard other something like that. There has to be no trace what so ever of root, twrp and so on. My knox is 0x1. Thanks!
