I chose OnePlusNote Nord N10 5g from the list. Is there a step-by-step guide on how this works? So many different comments, help, cross-references.... Then what is LineageOS ?? do I need this ?? The most important question is how do I root this thing?? Downloading version 10 requires Windows, but I don't have the option because I have Linux. I had Windows decades ago... I have no idea how this will continue, please help me out. Otherwise I'll sell the thing again and it'll be a trip!
