I brought a K30 Pro with china rom, when I insert my sim(4G) in it. It can show the 5G
And I flash eu ROM on next day, my sim can't show 5G. Then I flash back to china rom, it also can't show 5G.
I am not sure the K30 pro is losing the 5G during the flash rom. But my sim was also 4G plan. NOT 5G. The ISP was still building the 5G.
How can I make sure the K30 pro 5G function was working normal?
Thanks!
