  1. Great site, thank you. I have been bequeathed a Samsung S8 which is most probably network locked. It has been flashed with a custom ROM and I need to flash with stock ROM. I want to change carrier – will the flashing unlock the phone? If not will I need to install stock firmware for the original carrier (Telstra I think) – unlock – and then install firmware for preferred carrier?
    Hope this makes sense.
