Note 10 5G Korean Import - No 5G signal in UK

[Allografter]

Hi everyone. I've recently imported the Note 10 5G from Korea (SM-N971N) and for the life of me I cannot get 5G reception on the phone despite a 5G ready SIM card and being in a 5G area. I've tried various hidden menu access to the bands on the phone and it supports n78 so should pick up all UK networks but still can't get it to receive a 5G signal. The phone is 5G capable but I wonder whether the antenna is locked. Anyone know how I can get the 5G signal to be received? Thanks in advance.

Hi,
You will need to change ur settings. CCS

What do you mean? Do you mean change the CSC with Odin?

[Aklima]

Yes.

Can you be more specific? To which CSC? The current CSC is KOO, which is the unbranded Korean CSC whilst all the other available CSCs for this model are also all Korean and are carrier branded. There is no global CSC for this phone. Thanks.

You need to change your csc to BTU (UK Unbranded)

[RuthlessAfro24]

And that requires using a tool called samkey

It's not possible as this device / firmware only supports Korean CSCs.

I didn't think so and in any case the model number SM-N971N isn't supported by SamKEY.

Do you know why the 5G antenna isn't working in the UK and is there anything I can do about it?
