    EVR to BTU?

    Hi, I need some advice, can I replace my firmware from EVR- G920FXXU3QJF-G920FEVR3QOJF to BTU-G920FXXU3COI9-G920FBTU3COJ1 my phone is locked to EE uk, and I have an unlock code for it. Do I have to unlock it before re-flashing.

    If you have an unlock code then unlock before installing the BTU firmware.
    You do realise that by installing BTU firmware you will lose voice calls over LTE (VoLTE)

    Also may be a problem as the BTU is a downgrade and so your EVR bootloader may block it.
    If so, you will need the BTU PIT file to flash the firmware.
