Change CSC

[Anonymous User]

Hello,

I am a UK resident. I bought a Note 20 Ultra 5G, as a grey import, from Singapore.

My device is dual-SIM, and I believe the UK version is also dual-SIM.

Is there a way I can change the CSC of my device and get a UK firmware build onto it?

Thank you in advance.

No since Android 11 with the latest security it is not possible anymore! Means that he still has the security earlier then January 2021!

Doesn't matter with which dialler you try, it all depends which security you have, When you have the security earlier January 2021 then it works!

When you know someone from Samsung and works on the server with firmwares then they can change it when they want, don't know what price they will charge because needs to be done beside the books because it is not allowed normally!

Download SamFW tool and put it on your laptop/PC and you can unlock FRP and change CSC to BTU without wiping your device.
