Hello, i just installed the latest version of the rom, coming from samsung stock firmware, for the FU variant.
Everything during installation went good, but i can't get nor wifi or cellular data to work.
Does there's a specific fix for this? Or maybe i forgot to flash something first, like a kernel or samsung firmware?

FIXED: For the cellular data bug, just reboot the phone. It will disappear by itself.
For the wifi, i needed to flash the latest stock samsung firmware via Odin first, and just then flash the Rom. That fixed it.
I would recommend you try this .
i run it at my main phone .
works fine with no bugs .
it was updated 2 months ago and its still in developement .

Pretty Good ROM
First of all welcome :), second the message "set warranty Bit kernel" is not dangerous, so, that's why u can't get rid off
And third you can change it through substratum theme app. It'll be able change the actually theme and icons as well would be fantastic if u try VALERIE Theme for substratum app
By the way this ROM is discontinued and if u want something new or a" potato fresh" @vl_w made an unofficial ROM lineage os 15.1 for our devices :laugh: but it is still a beta .. Or change for lineage os 14.1 made for vl_w but edited by my friend @Deno_developer. He changed the boot animation instead of the boring lineage boot animation and Google pixel icons .. Try it :) I thought that it was fantastic rom
