    Galaxy A90 5G SM-A908B Firmware help?

    Hi Guys a little help would be very much appreciated .
    I have a Galaxy A90 5G SM-A908B received as an upgrade from O2 and my Vodafone SIM does work in it but the WIFI CALLING feature is missing.
    I have had a look through the forum to see if anybody else has upgraded their firmware on the Galaxy A90 5G and it looks like I might be the first.
    There is no coverage from any network at my home so I use a Sure Signal from Vodafone which is not an ideal solution as Vodafone no longer support them.
    I want to run Vodafone UK firmware on my A90 5G to be able use WIFI CALLING on the Vodafone UK network at home and I have down loaded Smart Switch and the A908BXXU4BTI3_A908BOVF4BTH1_VOD.zip which I hope is the correct firmware files.
    Does anybody know if the A908BXXU4BTI3_A908BOVF4BTH1_VOD.zip will give me access to the WIFI CALLING feature?
    When downloading firmware to the phone is it neccessary to have the SIM in or does it not matter?
    I think I have attached a screen shot of the firmware currently on the Phone if that helps

    Thank you for any help
    Mike

    Hi there

    It's the correct file

    I'm not sure WiFi-calling will work when flashing that file...

    When you do: flash AP BL CP & CSC_OVF (NOT HOME_CSC) with Odin 3.14.x. Your device will reset afterwards. Your SIM-card must be IN your device while flashing.

    Do you have a Vodafone SIM-card?

    Yes I have had a Vodafone UK SIM-card for many years.
